In addition to numerous new and upgraded packages and modules, this release has the following highlights: + +- Installation on UEFI systems is now supported. See [](#sec-installation) for details. + +- Systemd has been updated to version 212, which has [numerous improvements](http://cgit.freedesktop.org/systemd/systemd/plain/NEWS?id=v212). NixOS now automatically starts systemd user instances when you log in. You can define global user units through the `systemd.unit.*` options. + +- NixOS is now based on Glibc 2.19 and GCC 4.8. + +- The default Linux kernel has been updated to 3.12. + +- KDE has been updated to 4.12. + +- GNOME 3.10 experimental support has been added. + +- Nix has been updated to 1.7 ([details](https://nixos.org/nix/manual/#ssec-relnotes-1.7)). + +- NixOS now supports fully declarative management of users and groups. If you set `users.mutableUsers` to `false`, then the contents of `/etc/passwd` and `/etc/group` will be [congruent](https://www.usenix.org/legacy/event/lisa02/tech/full_papers/traugott/traugott_html/) to your NixOS configuration. For instance, if you remove a user from `users.extraUsers` and run `nixos-rebuild`, the user account will cease to exist. Also, imperative commands for managing users and groups, such as `useradd`, are no longer available. If `users.mutableUsers` is `true` (the default), then behaviour is unchanged from NixOS 13.10. + +- NixOS now has basic container support, meaning you can easily run a NixOS instance as a container in a NixOS host system. These containers are suitable for testing and experimentation but not production use, since they're not fully isolated from the host. See [](#ch-containers) for details. + +- Systemd units provided by packages can now be overridden from the NixOS configuration. For instance, if a package `foo` provides systemd units, you can say: + + ```nix + { + systemd.packages = [ pkgs.foo ]; + } + ``` + + to enable those units. You can then set or override unit options in the usual way, e.g. + + ```nix + { + systemd.services.foo.wantedBy = [ "multi-user.target" ]; + systemd.services.foo.serviceConfig.MemoryLimit = "512M"; + } + ``` + + When upgrading from a previous release, please be aware of the following incompatible changes: + +- Nixpkgs no longer exposes unfree packages by default. If your NixOS configuration requires unfree packages from Nixpkgs, you need to enable support for them explicitly by setting: + + ```nix + { + nixpkgs.config.allowUnfree = true; + } + ``` + + Otherwise, you get an error message such as: + + ```ShellSession + error: package ‘nvidia-x11-331.49-3.12.17’ in ‘…/nvidia-x11/default.nix:56’ + has an unfree license, refusing to evaluate + ``` + +- The Adobe Flash player is no longer enabled by default in the Firefox and Chromium wrappers. To enable it, you must set: + + ```nix + { + nixpkgs.config.allowUnfree = true; + nixpkgs.config.firefox.enableAdobeFlash = true; # for Firefox + nixpkgs.config.chromium.enableAdobeFlash = true; # for Chromium + } + ``` + +- The firewall is now enabled by default. If you don't want this, you need to disable it explicitly: + + ```nix + { + networking.firewall.enable = false; + } + ``` + +- The option `boot.loader.grub.memtest86` has been renamed to `boot.loader.grub.memtest86.enable`. + +- The `mysql55` service has been merged into the `mysql` service, which no longer sets a default for the option `services.mysql.package`. + +- Package variants are now differentiated by suffixing the name, rather than the version. For instance, `sqlite-3.8.4.3-interactive` is now called `sqlite-interactive-3.8.4.3`. This ensures that `nix-env -i sqlite` is unambiguous, and that `nix-env -u` won't "upgrade" `sqlite` to `sqlite-interactive` or vice versa. Notably, this change affects the Firefox wrapper (which provides plugins), as it is now called `firefox-wrapper`. So when using `nix-env`, you should do `nix-env -e firefox; nix-env -i firefox-wrapper` if you want to keep using the wrapper. This change does not affect declarative package management, since attribute names like `pkgs.firefoxWrapper` were already unambiguous. + +- The symlink `/etc/ca-bundle.crt` is gone. Programs should instead use the environment variable `OPENSSL_X509_CERT_FILE` (which points to `/etc/ssl/certs/ca-bundle.crt`). diff --git a/nixos/doc/manual/release-notes/rl-1412.section.md b/nixos/doc/manual/release-notes/rl-1412.section.md new file mode 100644 index 00000000000..683f1e45f09 --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-1412.section.md @@ -0,0 +1,171 @@ +# Release 14.12 ("Caterpillar", 2014/12/30) {#sec-release-14.12} + +In addition to numerous new and upgraded packages, this release has the following highlights: + +- Systemd has been updated to version 217, which has numerous [improvements.](http://lists.freedesktop.org/archives/systemd-devel/2014-October/024662.html) + +- [Nix has been updated to 1.8.](https://www.mail-archive.com/nix-dev@lists.science.uu.nl/msg13957.html) + +- NixOS is now based on Glibc 2.20. + +- KDE has been updated to 4.14. + +- The default Linux kernel has been updated to 3.14. + +- If `users.mutableUsers` is enabled (the default), changes made to the declaration of a user or group will be correctly realised when running `nixos-rebuild`.

The line `imports = [ <nixpkgs/nixos/modules/programs/virtualbox.nix> ]` is no longer necessary, use `services.virtualboxHost.enable = true` instead. + + Also, hardening mode is now enabled by default, which means that unless you want to use USB support, you no longer need to be a member of the `vboxusers` group. + +- Chromium has been updated to 39.0.2171.65. `enablePepperPDF` is now enabled by default. `chromium*Wrapper` packages no longer exist, because upstream removed NSAPI support. `chromium-stable` has been renamed to `chromium`. + +- Python packaging documentation is now part of nixpkgs manual. To override the python packages available to a custom python you now use `pkgs.pythonFull.buildEnv.override` instead of `pkgs.pythonFull.override`. + +- `boot.resumeDevice = "8:6"` is no longer supported. Most users will want to leave it undefined, which takes the swap partitions automatically. There is an evaluation assertion to ensure that the string starts with a slash. + +- The system-wide default timezone for NixOS installations changed from `CET` to `UTC`.

Detailed instructions on how to use that infrastructure can be found in the [User\'s Guide to the Haskell Infrastructure](https://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell-infrastructure). Users migrating from an earlier release may find helpful information below, in the list of backwards-incompatible changes. Furthermore, we distribute 51(!) additional Haskell package sets that provide every single [LTS Haskell](http://www.stackage.org/) release since version 0.0 as well as the most recent [Stackage Nightly](http://www.stackage.org/) snapshot. The announcement [\"Full Stackage Support in Nixpkgs\"](https://nixos.org/nix-dev/2015-September/018138.html) gives additional details. + +- Nix has been updated to version 1.10, which among other improvements enables cryptographic signatures on binary caches for improved security. + +- You can now keep your NixOS system up to date automatically by setting + +```nix +{ + system.autoUpgrade.enable = true; +} +``` + +This will cause the system to periodically check for updates in your current channel and run `nixos-rebuild`. + +- This release is based on Glibc 2.21, GCC 4.9 and Linux 3.18. + +- GNOME has been upgraded to 3.16. + +- Xfce has been upgraded to 4.12. + +- KDE 5 has been upgraded to KDE Frameworks 5.10, Plasma 5.3.2 and Applications 15.04.3.

NixOps sets the state version of existing deployments automatically. + +- `cron` is no longer enabled by default, unless you have a non-empty `services.cron.systemCronJobs`. To force `cron` to be enabled, set `services.cron.enable = true`. + +- Nix now requires binary caches to be cryptographically signed. If you have unsigned binary caches that you want to continue to use, you should set `nix.requireSignedBinaryCaches = false`. + +- Steam now doesn\'t need root rights to work. Instead of using `*-steam-chrootenv`, you should now just run `steam`. `steamChrootEnv` package was renamed to `steam`, and old `steam` package \-- to `steamOriginal`. + +- CMPlayer has been renamed to bomi upstream. Package `cmplayer` was accordingly renamed to `bomi` + +- Atom Shell has been renamed to Electron upstream. Package `atom-shell` was accordingly renamed to `electron` + +- Elm is not released on Hackage anymore. You should now use `elmPackages.elm` which contains the latest Elm platform. + +- The CUPS printing service has been updated to version `2.0.2`. Furthermore its systemd service has been renamed to `cups.service`. + + Local printers are no longer shared or advertised by default. This behavior can be changed by enabling `services.printing.defaultShared` or `services.printing.browsing` respectively. + +- The VirtualBox host and guest options have been named more consistently. They can now found in `virtualisation.virtualbox.host.*` instead of `services.virtualboxHost.*` and `virtualisation.virtualbox.guest.*` instead of `services.virtualboxGuest.*`. + + Also, there now is support for the `vboxsf` file system using the `fileSystems` configuration attribute. An example of how this can be used in a configuration: + +```nix +{ + fileSystems."/shiny" = { + device = "myshinysharedfolder"; + fsType = "vboxsf"; + }; +} +``` + +- \"`nix-env -qa`\" no longer discovers Haskell packages by name. The only packages visible in the global scope are `ghc`, `cabal-install`, and `stack`, but all other packages are hidden. The reason for this inconvenience is the sheer size of the Haskell package set. Name-based lookups are expensive, and most `nix-env -qa` operations would become much slower if we\'d add the entire Hackage database into the top level attribute set. Instead, the list of Haskell packages can be displayed by running: + +```ShellSession +nix-env -f "<nixpkgs>" -qaP -A haskellPackages +``` + +Executable programs written in Haskell can be installed with: + +```ShellSession +nix-env -f "<nixpkgs>" -iA haskellPackages.pandoc +``` + +Installing Haskell _libraries_ this way, however, is no longer supported. See the next item for more details. + +- Previous versions of NixOS came with a feature called `ghc-wrapper`, a small script that allowed GHC to transparently pick up on libraries installed in the user\'s profile. This feature has been deprecated; `ghc-wrapper` was removed from the distribution. The proper way to register Haskell libraries with the compiler now is the `haskellPackages.ghcWithPackages` function. The [User\'s Guide to the Haskell Infrastructure](https://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell-infrastructure) provides more information about this subject. + +- All Haskell builds that have been generated with version 1.x of the `cabal2nix` utility are now invalid and need to be re-generated with a current version of `cabal2nix` to function. The most recent version of this tool can be installed by running `nix-env -i cabal2nix`. + +- The `haskellPackages` set in Nixpkgs used to have a function attribute called `extension` that users could override in their `~/.nixpkgs/config.nix` files to configure additional attributes, etc. That function still exists, but it\'s now called `overrides`. + +- The OpenBLAS library has been updated to version `0.2.14`. Support for the `x86_64-darwin` platform was added. Dynamic architecture detection was enabled; OpenBLAS now selects microarchitecture-optimized routines at runtime, so optimal performance is achieved without the need to rebuild OpenBLAS locally. OpenBLAS has replaced ATLAS in most packages which use an optimized BLAS or LAPACK implementation. + +- The `phpfpm` is now using the default PHP version (`pkgs.php`) instead of PHP 5.4 (`pkgs.php54`). + +- The `locate` service no longer indexes the Nix store by default, preventing packages with potentially numerous versions from cluttering the output. Indexing the store can be activated by setting `services.locate.includeStore = true`. + +- The Nix expression search path (`NIX_PATH`) no longer contains `/etc/nixos/nixpkgs` by default. You can override `NIX_PATH` by setting `nix.nixPath`. + +- Python 2.6 has been marked as broken (as it no longer receives security updates from upstream). + +- Any use of module arguments such as `pkgs` to access library functions, or to define `imports` attributes will now lead to an infinite loop at the time of the evaluation. + + In case of an infinite loop, use the `--show-trace` command line argument and read the line just above the error message. + + ```ShellSession + $ nixos-rebuild build --show-trace + … + while evaluating the module argument `pkgs' in "/etc/nixos/my-module.nix": + infinite recursion encountered + ``` + + Any use of `pkgs.lib`, should be replaced by `lib`, after adding it as argument of the module. The following module + + ```nix + { config, pkgs, ... }: + + with pkgs.lib; + + { + options = { + foo = mkOption { … }; + }; + config = mkIf config.foo { … }; + } + ``` + + should be modified to look like: + + ```nix + { config, pkgs, lib, ... }: + + with lib; + + { + options = { + foo = mkOption { option declaration }; + }; + config = mkIf config.foo { option definition }; + } + ``` + + When `pkgs` is used to download other projects to import their modules, and only in such cases, it should be replaced by `(import <nixpkgs> {})`. The following module + + ```nix + { config, pkgs, ... }: + + let + myProject = pkgs.fetchurl { + src = url; + sha256 = hash; + }; + in + + { + imports = [ "${myProject}/module.nix" ]; + } + ``` + + should be modified to look like: + + ```nix + { config, pkgs, ... }: + + let + myProject = (import <nixpkgs> {}).fetchurl { + src = url; + sha256 = hash; + }; + in + + { + imports = [ "${myProject}/module.nix" ]; + } + ``` + +Other notable improvements: + +- The nixos and nixpkgs channels were unified, so one _can_ use `nix-env -iA nixos.bash` instead of `nix-env -iA nixos.pkgs.bash`. See [the commit](https://github.com/NixOS/nixpkgs/commit/2cd7c1f198) for details. + +- Users running an SSH server who worry about the quality of their `/etc/ssh/moduli` file with respect to the [vulnerabilities discovered in the Diffie-Hellman key exchange](https://stribika.github.io/2015/01/04/secure-secure-shell.html) can now replace OpenSSH\'s default version with one they generated themselves using the new `services.openssh.moduliFile` option. + +- A newly packaged TeX Live 2015 is provided in `pkgs.texlive`, split into 6500 nix packages. For basic user documentation see [the source](https://github.com/NixOS/nixpkgs/blob/release-15.09/pkgs/tools/typesetting/tex/texlive/default.nix#L1). Beware of [an issue](https://github.com/NixOS/nixpkgs/issues/9757) when installing a too large package set. The plan is to deprecate and maybe delete the original TeX packages until the next release. + +- `buildEnv.env` on all Python interpreters is now available for nix-shell interoperability. diff --git a/nixos/doc/manual/release-notes/rl-1603.section.md b/nixos/doc/manual/release-notes/rl-1603.section.md new file mode 100644 index 00000000000..dce879ec16d --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-1603.section.md @@ -0,0 +1,282 @@ +# Release 16.03 ("Emu", 2016/03/31) {#sec-release-16.03} + +In addition to numerous new and upgraded packages, this release has the following highlights: + +- Systemd 229, bringing [numerous improvements](https://github.com/systemd/systemd/blob/v229/NEWS) over 217. + +- Linux 4.4 (was 3.18). + +- GCC 5.3 (was 4.9).

An ongoing project, the goal of exact reproducibility is to allow binaries to be verified independently (e.g., a user might only trust binaries that appear in three independent binary caches). + +- Perl 5.22. + +The following new services were added since the last release: + +- `services/monitoring/longview.nix` + +- `hardware/video/webcam/facetimehd.nix` + +- `i18n/input-method/default.nix` + +- `i18n/input-method/fcitx.nix` + +- `i18n/input-method/ibus.nix` + +- `i18n/input-method/nabi.nix` + +- `i18n/input-method/uim.nix` + +- `programs/fish.nix` + +- `security/acme.nix` + +- `security/audit.nix` + +- `security/oath.nix` + +- `services/hardware/irqbalance.nix` + +- `services/mail/dspam.nix` + +- `services/mail/opendkim.nix` + +- `services/mail/postsrsd.nix` + +- `services/mail/rspamd.nix` + +- `services/mail/rmilter.nix` + +- `services/misc/autofs.nix` + +- `services/misc/bepasty.nix` + +- `services/misc/calibre-server.nix` + +- `services/misc/cfdyndns.nix` + +- `services/misc/gammu-smsd.nix` + +- `services/misc/mathics.nix` + +- `services/misc/matrix-synapse.nix` + +- `services/misc/octoprint.nix` + +- `services/monitoring/hdaps.nix` + +- `services/monitoring/heapster.nix` + +- `services/monitoring/longview.nix` + +- `services/network-filesystems/netatalk.nix` + +- `services/network-filesystems/xtreemfs.nix` + +- `services/networking/autossh.nix` + +- `services/networking/dnschain.nix` + +- `services/networking/gale.nix` + +- `services/networking/miniupnpd.nix` + +- `services/networking/namecoind.nix` + +- `services/networking/ostinato.nix` + +- `services/networking/pdnsd.nix` + +- `services/networking/shairport-sync.nix` + +- `services/networking/supplicant.nix` + +- `services/search/kibana.nix` + +- `services/security/haka.nix` + +- `services/security/physlock.nix` + +- `services/web-apps/pump.io.nix` + +- `services/x11/hardware/libinput.nix` + +- `services/x11/window-managers/windowlab.nix` + +- `system/boot/initrd-network.nix` + +- `system/boot/initrd-ssh.nix` + +- `system/boot/loader/loader.nix` + +- `system/boot/networkd.nix` + +- `system/boot/resolved.nix` + +- `virtualisation/lxd.nix` + +- `virtualisation/rkt.nix` + +When upgrading from a previous release, please be aware of the following incompatible changes: + +- We no longer produce graphical ISO images and VirtualBox images for `i686-linux`. A minimal ISO image is still provided. + +- Firefox and similar browsers are now _wrapped by default_. The package and attribute names are plain `firefox` or `midori`, etc. Backward-compatibility attributes were set up, but note that `nix-env -u` will _not_ update your current `firefox-with-plugins`; you have to uninstall it and install `firefox` instead. + +- `wmiiSnap` has been replaced with `wmii_hg`, but `services.xserver.windowManager.wmii.enable` has been updated respectively so this only affects you if you have explicitly installed `wmiiSnap`. + +- `jobs` NixOS option has been removed. It served as compatibility layer between Upstart jobs and SystemD services. All services have been rewritten to use `systemd.services` + +- `wmiimenu` is removed, as it has been removed by the developers upstream. Use `wimenu` from the `wmii-hg` package. + +- Gitit is no longer automatically added to the module list in NixOS and as such there will not be any manual entries for it. You will need to add an import statement to your NixOS configuration in order to use it, e.g. + + ```nix + { + imports = [ <nixpkgs/nixos/modules/services/misc/gitit.nix> ]; + } + ``` + + will include the Gitit service configuration options. + +- `nginx` does not accept flags for enabling and disabling modules anymore. Instead it accepts `modules` argument, which is a list of modules to be built in. All modules now reside in `nginxModules` set. Example configuration: + + ```nix + nginx.override { + modules = [ nginxModules.rtmp nginxModules.dav nginxModules.moreheaders ]; + } + ``` + +- `s3sync` is removed, as it hasn\'t been developed by upstream for 4 years and only runs with ruby 1.8. For an actively-developer alternative look at `tarsnap` and others. + +- `ruby_1_8` has been removed as it\'s not supported from upstream anymore and probably contains security issues. + +- `tidy-html5` package is removed. Upstream only provided `(lib)tidy5` during development, and now they went back to `(lib)tidy` to work as a drop-in replacement of the original package that has been unmaintained for years. You can (still) use the `html-tidy` package, which got updated to a stable release from this new upstream. + +- `extraDeviceOptions` argument is removed from `bumblebee` package. Instead there are now two separate arguments: `extraNvidiaDeviceOptions` and `extraNouveauDeviceOptions` for setting extra X11 options for nvidia and nouveau drivers, respectively. + +- The `Ctrl+Alt+Backspace` key combination no longer kills the X server by default. There\'s a new option `services.xserver.enableCtrlAltBackspace` allowing to enable the combination again. + +- `emacsPackagesNg` now contains all packages from the ELPA, MELPA, and MELPA Stable repositories. + +- Data directory for Postfix MTA server is moved from `/var/postfix` to `/var/lib/postfix`. Old configurations are migrated automatically. `service.postfix` module has also received many improvements, such as correct directories\' access rights, new `aliasFiles` and `mapFiles` options and more. + +- Filesystem options should now be configured as a list of strings, not a comma-separated string. The old style will continue to work, but print a warning, until the 16.09 release. An example of the new style: + + ```nix + { + fileSystems."/example" = { + device = "/dev/sdc"; + fsType = "btrfs"; + options = [ "noatime" "compress=lzo" "space_cache" "autodefrag" ]; + }; + } + ``` + +- CUPS, installed by `services.printing` module, now has its data directory in `/var/lib/cups`. Old configurations from `/etc/cups` are moved there automatically, but there might be problems. Also configuration options `services.printing.cupsdConf` and `services.printing.cupsdFilesConf` were removed because they had been allowing one to override configuration variables required for CUPS to work at all on NixOS. For most use cases, `services.printing.extraConf` and new option `services.printing.extraFilesConf` should be enough; if you encounter a situation when they are not, please file a bug. + + There are also Gutenprint improvements; in particular, a new option `services.printing.gutenprint` is added to enable automatic updating of Gutenprint PPMs; it\'s greatly recommended to enable it instead of adding `gutenprint` to the `drivers` list. + +- `services.xserver.vaapiDrivers` has been removed. Use `hardware.opengl.extraPackages{,32}` instead. You can also specify VDPAU drivers there. + +- `programs.ibus` moved to `i18n.inputMethod.ibus`. The option `programs.ibus.plugins` changed to `i18n.inputMethod.ibus.engines` and the option to enable ibus changed from `programs.ibus.enable` to `i18n.inputMethod.enabled`. `i18n.inputMethod.enabled` should be set to the used input method name, `"ibus"` for ibus. An example of the new style: + + ```nix + { + i18n.inputMethod.enabled = "ibus"; + i18n.inputMethod.ibus.engines = with pkgs.ibus-engines; [ anthy mozc ]; + } + ``` + + That is equivalent to the old version: + + ```nix + { + programs.ibus.enable = true; + programs.ibus.plugins = with pkgs; [ ibus-anthy mozc ]; + } + ``` + +- `services.udev.extraRules` option now writes rules to `99-local.rules` instead of `10-local.rules`. This makes all the user rules apply after others, so their results wouldn\'t be overriden by anything else. + +- Large parts of the `services.gitlab` module has been been rewritten. There are new configuration options available. The `stateDir` option was renamned to `statePath` and the `satellitesDir` option was removed. Please review the currently available options. + +- The option `services.nsd.zones.<name>.data` no longer interpret the dollar sign (\$) as a shell variable, as such it should not be escaped anymore. Thus the following zone data: + + ```dns-zone + $ORIGIN example.com. + $TTL 1800 + @ IN SOA ns1.vpn.nbp.name. admin.example.com. ( + + ``` + + Should modified to look like the actual file expected by nsd: + + ```dns-zone + $ORIGIN example.com. + $TTL 1800 + @ IN SOA ns1.vpn.nbp.name. admin.example.com. ( + + ``` + +- `service.syncthing.dataDir` options now has to point to exact folder where syncthing is writing to. Example configuration should look something like: + + ```nix + { + services.syncthing = { + enable = true; + dataDir = "/home/somebody/.syncthing"; + user = "somebody"; + }; + } + ``` + +- `networking.firewall.allowPing` is now enabled by default. Users are encouraged to configure an appropriate rate limit for their machines using the Kernel interface at `/proc/sys/net/ipv4/icmp_ratelimit` and `/proc/sys/net/ipv6/icmp/ratelimit` or using the firewall itself, i.e. by setting the NixOS option `networking.firewall.pingLimit`. + +- Systems with some broadcom cards used to result into a generated config that is no longer accepted. If you get errors like + + ```ShellSession + error: path ‘/nix/store/*-broadcom-sta-*’ does not exist and cannot be created + ``` + + you should either re-run `nixos-generate-config` or manually replace `"${config.boot.kernelPackages.broadcom_sta}"` by `config.boot.kernelPackages.broadcom_sta` in your `/etc/nixos/hardware-configuration.nix`. More discussion is on [ the github issue](https://github.com/NixOS/nixpkgs/pull/12595). + +- The `services.xserver.startGnuPGAgent` option has been removed. GnuPG 2.1.x changed the way the gpg-agent works, and that new approach no longer requires (or even supports) the \"start everything as a child of the agent\" scheme we\'ve implemented in NixOS for older versions. To configure the gpg-agent for your X session, add the following code to `~/.bashrc` or some file that's sourced when your shell is started: + + ```shell + GPG_TTY=$(tty) + export GPG_TTY + ``` + + If you want to use gpg-agent for SSH, too, add the following to your session initialization (e.g. `displayManager.sessionCommands`) + + ```shell + gpg-connect-agent /bye + unset SSH_AGENT_PID + export SSH_AUTH_SOCK="''${HOME}/.gnupg/S.gpg-agent.ssh" + ``` + + and make sure that + + ```conf + enable-ssh-support + ``` + + is included in your `~/.gnupg/gpg-agent.conf`. You will need to use `ssh-add` to re-add your ssh keys. If gpg's automatic transformation of the private keys to the new format fails, you will need to re-import your private keyring as well: + + ```ShellSession + gpg --import ~/.gnupg/secring.gpg + ``` + + The `gpg-agent(1)` man page has more details about this subject, i.e. in the \"EXAMPLES\" section. + +Other notable improvements: + +- `ejabberd` module is brought back and now works on NixOS. + +- Input method support was improved. New NixOS modules (fcitx, nabi and uim), fcitx engines (chewing, hangul, m17n, mozc and table-other) and ibus engines (hangul and m17n) have been added. diff --git a/nixos/doc/manual/release-notes/rl-1609.section.md b/nixos/doc/manual/release-notes/rl-1609.section.md new file mode 100644 index 00000000000..075f0cf52cd --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-1609.section.md @@ -0,0 +1,73 @@ +# Release 16.09 ("Flounder", 2016/09/30) {#sec-release-16.09} + +In addition to numerous new and upgraded packages, this release has the following highlights: + +- Many NixOS configurations and Nix packages now use significantly less disk space, thanks to the [extensive work on closure size reduction](https://github.com/NixOS/nixpkgs/issues/7117). For example, the closure size of a minimal NixOS container went down from \~424 MiB in 16.03 to \~212 MiB in 16.09, while the closure size of Firefox went from \~651 MiB to \~259 MiB. + +- To improve security, packages are now [built using various hardening features](https://github.com/NixOS/nixpkgs/pull/12895). See the Nixpkgs manual for more information. + +- Support for PXE netboot. See [](#sec-booting-from-pxe) for documentation. + +- X.org server 1.18. If you use the `ati_unfree` driver, 1.17 is still used due to an ABI incompatibility. + +- This release is based on Glibc 2.24, GCC 5.4.0 and systemd 231.

This may require changes to any custom packages to make them build again; see the relevant chapter in the Nixpkgs manual for more information. (Additional caveat to packagers: some packaging conventions related to multiple-output packages [were changed](https://github.com/NixOS/nixpkgs/pull/14766) late (August 2016) in the release cycle and differ from the initial introduction of multiple outputs.) + +- Previous versions of Nixpkgs had support for all versions of the LTS Haskell package set. That support has been dropped. The previously provided `haskell.packages.lts-x_y` package sets still exist in name to aviod breaking user code, but these package sets don\'t actually contain the versions mandated by the corresponding LTS release. Instead, our package set it loosely based on the latest available LTS release, i.e. LTS 7.x at the time of this writing. New releases of NixOS and Nixpkgs will drop those old names entirely. [The motivation for this change](https://nixos.org/nix-dev/2016-June/020585.html) has been discussed at length on the `nix-dev` mailing list and in [Github issue \#14897](https://github.com/NixOS/nixpkgs/issues/14897). Development strategies for Haskell hackers who want to rely on Nix and NixOS have been described in [another nix-dev article](https://nixos.org/nix-dev/2016-June/020642.html). + +- Shell aliases for systemd sub-commands [were dropped](https://github.com/NixOS/nixpkgs/pull/15598): `start`, `stop`, `restart`, `status`. + +- Redis now binds to 127.0.0.1 only instead of listening to all network interfaces. This is the default behavior of Redis 3.2 + +- `/var/empty` is now immutable. Activation script runs `chattr +i` to forbid any modifications inside the folder. See [ the pull request](https://github.com/NixOS/nixpkgs/pull/18365) for what bugs this caused. + +- Gitlab\'s maintainance script `gitlab-runner` was removed and split up into the more clearer `gitlab-run` and `gitlab-rake` scripts, because `gitlab-runner` is a component of Gitlab CI. + +- `services.xserver.libinput.accelProfile` default changed from `flat` to `adaptive`, as per [ official documentation](https://wayland.freedesktop.org/libinput/doc/latest/group__config.html#gad63796972347f318b180e322e35cee79). + +- `fonts.fontconfig.ultimate.rendering` was removed because our presets were obsolete for some time. New presets are hardcoded into FreeType; you can select a preset via `fonts.fontconfig.ultimate.preset`. You can customize those presets via ordinary environment variables, using `environment.variables`. + +- The `audit` service is no longer enabled by default. Use `security.audit.enable = true` to explicitly enable it. + +- `pkgs.linuxPackages.virtualbox` now contains only the kernel modules instead of the VirtualBox user space binaries. If you want to reference the user space binaries, you have to use the new `pkgs.virtualbox` instead. + +- `goPackages` was replaced with separated Go applications in appropriate `nixpkgs` categories. Each Go package uses its own dependency set. There\'s also a new `go2nix` tool introduced to generate a Go package definition from its Go source automatically. + +- `services.mongodb.extraConfig` configuration format was changed to YAML. + +- PHP has been upgraded to 7.0 + +Other notable improvements: + +- Revamped grsecurity/PaX support. There is now only a single general-purpose distribution kernel and the configuration interface has been streamlined. Desktop users should be able to simply set + + ```nix + { + security.grsecurity.enable = true; + } + ``` + + to get a reasonably secure system without having to sacrifice too much functionality. + +- Special filesystems, like `/proc`, `/run` and others, now have the same mount options as recommended by systemd and are unified across different places in NixOS. Mount options are updated during `nixos-rebuild switch` if possible. One benefit from this is improved security --- most such filesystems are now mounted with `noexec`, `nodev` and/or `nosuid` options. + +- The reverse path filter was interfering with DHCPv4 server operation in the past. An exception for DHCPv4 and a new option to log packets that were dropped due to the reverse path filter was added (`networking.firewall.logReversePathDrops`) for easier debugging. + +- Containers configuration within `containers.<name>.config` is [now properly typed and checked](https://github.com/NixOS/nixpkgs/pull/17365). In particular, partial configurations are merged correctly. + +- The directory container setuid wrapper programs, `/var/setuid-wrappers`, [is now updated atomically to prevent failures if the switch to a new configuration is interrupted.](https://github.com/NixOS/nixpkgs/pull/18124) + +- `services.xserver.startGnuPGAgent` has been removed due to GnuPG 2.1.x bump. See [ how to achieve similar behavior](https://github.com/NixOS/nixpkgs/commit/5391882ebd781149e213e8817fba6ac3c503740c).

See `lib.trivial.extends` for what those parameters represent. + +- `ansible` now defaults to ansible version 2 as version 1 has been removed due to a serious [ vulnerability](https://www.computest.nl/advisories/CT-2017-0109_Ansible.txt) unpatched by upstream. + +- `gnome` alias has been removed along with `gtk`, `gtkmm` and several others. Now you need to use versioned attributes, like `gnome3`. + +- The attribute name of the Radicale daemon has been changed from `pythonPackages.radicale` to `radicale`. + +- The `stripHash` bash function in `stdenv` changed according to its documentation; it now outputs the stripped name to `stdout` instead of putting it in the variable `strippedName`. + +- PHP now scans for extra configuration .ini files in /etc/php.d instead of /etc. This prevents accidentally loading non-PHP .ini files that may be in /etc. + +- Two lone top-level dict dbs moved into `dictdDBs`. This affects: `dictdWordnet` which is now at `dictdDBs.wordnet` and `dictdWiktionary` which is now at `dictdDBs.wiktionary` + +- Parsoid service now uses YAML configuration format. `service.parsoid.interwikis` is now called `service.parsoid.wikis` and is a list of either API URLs or attribute sets as specified in parsoid\'s documentation. + +- `Ntpd` was replaced by `systemd-timesyncd` as the default service to synchronize system time with a remote NTP server. The old behavior can be restored by setting `services.ntp.enable` to `true`. Upstream time servers for all NTP implementations are now configured using `networking.timeServers`. + +- `service.nylon` is now declared using named instances. As an example: + + ```nix + { + services.nylon = { + enable = true; + acceptInterface = "br0"; + bindInterface = "tun1"; + port = 5912; + }; + } + ``` + + should be replaced with: + + ```nix + { + services.nylon.myvpn = { + enable = true; + acceptInterface = "br0"; + bindInterface = "tun1"; + port = 5912; + }; + } + ``` + + this enables you to declare a SOCKS proxy for each uplink. + +- `overridePackages` function no longer exists. It is replaced by [ overlays](https://nixos.org/nixpkgs/manual/#sec-overlays-install). For example, the following code: + + ```nix + let + pkgs = import <nixpkgs> {}; + in + pkgs.overridePackages (self: super: ...) + ``` + + should be replaced by: + + ```nix + let + pkgs = import <nixpkgs> {}; + in + import pkgs.path { overlays = [(self: super: ...)]; } + ``` + +- Autoloading connection tracking helpers is now disabled by default. This default was also changed in the Linux kernel and is considered insecure if not configured properly in your firewall. If you need connection tracking helpers (i.e. for active FTP) please enable `networking.firewall.autoLoadConntrackHelpers` and tune `networking.firewall.connectionTrackingModules` to suit your needs. + +- `local_recipient_maps` is not set to empty value by Postfix service. It\'s an insecure default as stated by Postfix documentation. Those who want to retain this setting need to set it via `services.postfix.extraConfig`. + +- Iputils no longer provide ping6 and traceroute6. The functionality of these tools has been integrated into ping and traceroute respectively. To enforce an address family the new flags `-4` and `-6` have been added. One notable incompatibility is that specifying an interface (for link-local IPv6 for instance) is no longer done with the `-I` flag, but by encoding the interface into the address (`ping fe80::1%eth0`). + +- The socket handling of the `services.rmilter` module has been fixed and refactored. As rmilter doesn\'t support binding to more than one socket, the options `bindUnixSockets` and `bindInetSockets` have been replaced by `services.rmilter.bindSocket.*`. The default is still a unix socket in `/run/rmilter/rmilter.sock`. Refer to the options documentation for more information. + +- The `fetch*` functions no longer support md5, please use sha256 instead. + +- The dnscrypt-proxy module interface has been streamlined around the `extraArgs` option. Where possible, legacy option declarations are mapped to `extraArgs` but will emit warnings. The `resolverList` has been outright removed: to use an unlisted resolver, use the `customResolver` option. + +- torbrowser now stores local state under `~/.local/share/tor-browser` by default. Any browser profile data from the old location, `~/.torbrowser4`, must be migrated manually. + +- The ihaskell, monetdb, offlineimap and sitecopy services have been removed. + +## Other Notable Changes {#sec-release-17.03-notable-changes} + +- Module type system have a new extensible option types feature that allow to extend certain types, such as enum, through multiple option declarations of the same option across multiple modules. + +- `jre` now defaults to GTK UI by default. This improves visual consistency and makes Java follow system font style, improving the situation on HighDPI displays. This has a cost of increased closure size; for server and other headless workloads it\'s recommended to use `jre_headless`. + +- Python 2.6 interpreter and package set have been removed. + +- The Python 2.7 interpreter does not use modules anymore. Instead, all CPython interpreters now include the whole standard library except for \`tkinter\`, which is available in the Python package set. + +- Python 2.7, 3.5 and 3.6 are now built deterministically and 3.4 mostly. Minor modifications had to be made to the interpreters in order to generate deterministic bytecode. This has security implications and is relevant for those using Python in a `nix-shell`. See the Nixpkgs manual for details. + +- The Python package sets now use a fixed-point combinator and the sets are available as attributes of the interpreters. + +- The Python function `buildPythonPackage` has been improved and can be used to build from Setuptools source, Flit source, and precompiled Wheels. + +- When adding new or updating current Python libraries, the expressions should be put in separate files in `pkgs/development/python-modules` and called from `python-packages.nix`. + +- The dnscrypt-proxy service supports synchronizing the list of public resolvers without working DNS resolution. This fixes issues caused by the resolver list becoming outdated. It also improves the viability of DNSCrypt only configurations. + +- Containers using bridged networking no longer lose their connection after changes to the host networking. + +- ZFS supports pool auto scrubbing. + +- The bind DNS utilities (e.g. dig) have been split into their own output and are now also available in `pkgs.dnsutils` and it is no longer necessary to pull in all of `bind` to use them. + +- Per-user configuration was moved from `~/.nixpkgs` to `~/.config/nixpkgs`. The former is still valid for `config.nix` for backwards compatibility. diff --git a/nixos/doc/manual/release-notes/rl-1709.section.md b/nixos/doc/manual/release-notes/rl-1709.section.md new file mode 100644 index 00000000000..e5af22721b0 --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-1709.section.md @@ -0,0 +1,316 @@ +# Release 17.09 ("Hummingbird", 2017/09/??) {#sec-release-17.09} + +## Highlights {#sec-release-17.09-highlights} + +In addition to numerous new and upgraded packages, this release has the following highlights: + +- The GNOME version is now 3.24. KDE Plasma was upgraded to 5.10, KDE Applications to 17.08.1 and KDE Frameworks to 5.37. + +- The user handling now keeps track of deallocated UIDs/GIDs. When a user or group is revived, this allows it to be allocated the UID/GID it had before. A consequence is that UIDs and GIDs are no longer reused. + +- The module option `services.xserver.xrandrHeads` now causes the first head specified in this list to be set as the primary head. Apart from that, it\'s now possible to also set additional options by using an attribute set, for example: + + ```nix + { services.xserver.xrandrHeads = [ + "HDMI-0" + { + output = "DVI-0"; + primary = true; + monitorConfig = '' + Option "Rotate" "right" + ''; + } + ]; + } + ``` + + This will set the `DVI-0` output to be the primary head, even though `HDMI-0` is the first head in the list. + +- The handling of SSL in the `services.nginx` module has been cleaned up, renaming the misnamed `enableSSL` to `onlySSL` which reflects its original intention. This is not to be used with the already existing `forceSSL` which creates a second non-SSL virtual host redirecting to the SSL virtual host. This by chance had worked earlier due to specific implementation details. In case you had specified both please remove the `enableSSL` option to keep the previous behaviour. + + Another `addSSL` option has been introduced to configure both a non-SSL virtual host and an SSL virtual host with the same configuration. + + Options to configure `resolver` options and `upstream` blocks have been introduced. See their information for further details. + + The `port` option has been replaced by a more generic `listen` option which makes it possible to specify multiple addresses, ports and SSL configs dependant on the new SSL handling mentioned above. + +## New Services {#sec-release-17.09-new-services} + +The following new services were added since the last release: + +- `config/fonts/fontconfig-penultimate.nix` + +- `config/fonts/fontconfig-ultimate.nix` + +- `config/terminfo.nix` + +- `hardware/sensor/iio.nix` + +- `hardware/nitrokey.nix` + +- `hardware/raid/hpsa.nix` + +- `programs/browserpass.nix` + +- `programs/gnupg.nix` + +- `programs/qt5ct.nix` + +- `programs/slock.nix` + +- `programs/thefuck.nix` + +- `security/auditd.nix` + +- `security/lock-kernel-modules.nix` + +- `service-managers/docker.nix` + +- `service-managers/trivial.nix` + +- `services/admin/salt/master.nix` + +- `services/admin/salt/minion.nix` + +- `services/audio/slimserver.nix` + +- `services/cluster/kubernetes/default.nix` + +- `services/cluster/kubernetes/dns.nix` + +- `services/cluster/kubernetes/dashboard.nix` + +- `services/continuous-integration/hail.nix` + +- `services/databases/clickhouse.nix` + +- `services/databases/postage.nix` + +- `services/desktops/gnome3/gnome-disks.nix` + +- `services/desktops/gnome3/gpaste.nix` + +- `services/logging/SystemdJournal2Gelf.nix` + +- `services/logging/heartbeat.nix` + +- `services/logging/journalwatch.nix` + +- `services/logging/syslogd.nix` + +- `services/mail/mailhog.nix` + +- `services/mail/nullmailer.nix` + +- `services/misc/airsonic.nix` + +- `services/misc/autorandr.nix` + +- `services/misc/exhibitor.nix` + +- `services/misc/fstrim.nix` + +- `services/misc/gollum.nix` + +- `services/misc/irkerd.nix` + +- `services/misc/jackett.nix` + +- `services/misc/radarr.nix` + +- `services/misc/snapper.nix` + +- `services/monitoring/osquery.nix` + +- `services/monitoring/prometheus/collectd-exporter.nix` + +- `services/monitoring/prometheus/fritzbox-exporter.nix` + +- `services/network-filesystems/kbfs.nix` + +- `services/networking/dnscache.nix` + +- `services/networking/fireqos.nix` + +- `services/networking/iwd.nix` + +- `services/networking/keepalived/default.nix` + +- `services/networking/keybase.nix` + +- `services/networking/lldpd.nix` + +- `services/networking/matterbridge.nix` + +- `services/networking/squid.nix` + +- `services/networking/tinydns.nix` + +- `services/networking/xrdp.nix` + +- `services/security/shibboleth-sp.nix` + +- `services/security/sks.nix` + +- `services/security/sshguard.nix` + +- `services/security/torify.nix` + +- `services/security/usbguard.nix` + +- `services/security/vault.nix` + +- `services/system/earlyoom.nix` + +- `services/system/saslauthd.nix` + +- `services/web-apps/nexus.nix` + +- `services/web-apps/pgpkeyserver-lite.nix` + +- `services/web-apps/piwik.nix` + +- `services/web-servers/lighttpd/collectd.nix` + +- `services/web-servers/minio.nix` + +- `services/x11/display-managers/xpra.nix` + +- `services/x11/xautolock.nix` + +- `tasks/filesystems/bcachefs.nix` + +- `tasks/powertop.nix` + +## Backward Incompatibilities {#sec-release-17.09-incompatibilities} + +When upgrading from a previous release, please be aware of the following incompatible changes: + +- **In an Qemu-based virtualization environment, the network interface names changed from i.e. `enp0s3` to `ens3`.** + + This is due to a kernel configuration change. The new naming is consistent with those of other Linux distributions with systemd. See [\#29197](https://github.com/NixOS/nixpkgs/issues/29197) for more information. + + A machine is affected if the `virt-what` tool either returns `qemu` or `kvm` _and_ has interface names used in any part of its NixOS configuration, in particular if a static network configuration with `networking.interfaces` is used. + + Before rebooting affected machines, please ensure: + + - Change the interface names in your NixOS configuration. The first interface will be called `ens3`, the second one `ens8` and starting from there incremented by 1. + + - After changing the interface names, rebuild your system with `nixos-rebuild boot` to activate the new configuration after a reboot. If you switch to the new configuration right away you might lose network connectivity! If using `nixops`, deploy with `nixops deploy --force-reboot`. + +- The following changes apply if the `stateVersion` is changed to 17.09 or higher. For `stateVersion = "17.03"` or lower the old behavior is preserved. + + - The `postgres` default version was changed from 9.5 to 9.6. + + - The `postgres` superuser name has changed from `root` to `postgres` to more closely follow what other Linux distributions are doing. + + - The `postgres` default `dataDir` has changed from `/var/db/postgres` to `/var/lib/postgresql/$psqlSchema` where \$psqlSchema is 9.6 for example. + + - The `mysql` default `dataDir` has changed from `/var/mysql` to `/var/lib/mysql`. + + - Radicale\'s default package has changed from 1.x to 2.x. Instructions to migrate can be found [ here ](http://radicale.org/1to2/). It is also possible to use the newer version by setting the `package` to `radicale2`, which is done automatically when `stateVersion` is 17.09 or higher. The `extraArgs` option has been added to allow passing the data migration arguments specified in the instructions; see the `radicale.nix` NixOS test for an example migration. + +- The `aiccu` package was removed. This is due to SixXS [ sunsetting](https://www.sixxs.net/main/) its IPv6 tunnel. + +- The `fanctl` package and `fan` module have been removed due to the developers not upstreaming their iproute2 patches and lagging with compatibility to recent iproute2 versions. + +- Top-level `idea` package collection was renamed. All JetBrains IDEs are now at `jetbrains`. + +- `flexget`\'s state database cannot be upgraded to its new internal format, requiring removal of any existing `db-config.sqlite` which will be automatically recreated. + +- The `ipfs` service now doesn\'t ignore the `dataDir` option anymore. If you\'ve ever set this option to anything other than the default you\'ll have to either unset it (so the default gets used) or migrate the old data manually with + + ```ShellSession + dataDir=<valueOfDataDir> + mv /var/lib/ipfs/.ipfs/* $dataDir + rmdir /var/lib/ipfs/.ipfs + ``` + +- The `caddy` service was previously using an extra `.caddy` directory in the data directory specified with the `dataDir` option. The contents of the `.caddy` directory are now expected to be in the `dataDir`. + +- The `ssh-agent` user service is not started by default anymore. Use `programs.ssh.startAgent` to enable it if needed. There is also a new `programs.gnupg.agent` module that creates a `gpg-agent` user service. It can also serve as a SSH agent if `enableSSHSupport` is set. + +- The `services.tinc.networks.<name>.listenAddress` option had a misleading name that did not correspond to its behavior. It now correctly defines the ip to listen for incoming connections on. To keep the previous behaviour, use `services.tinc.networks.<name>.bindToAddress` instead. Refer to the description of the options for more details. + +- `tlsdate` package and module were removed. This is due to the project being dead and not building with openssl 1.1. + +- `wvdial` package and module were removed. This is due to the project being dead and not building with openssl 1.1. + +- `cc-wrapper`\'s setup-hook now exports a number of environment variables corresponding to binutils binaries, (e.g. `LD`, `STRIP`, `RANLIB`, etc). This is done to prevent packages\' build systems guessing, which is harder to predict, especially when cross-compiling. However, some packages have broken due to this---their build systems either not supporting, or claiming to support without adequate testing, taking such environment variables as parameters. + +- `services.firefox.syncserver` now runs by default as a non-root user. To accomodate this change, the default sqlite database location has also been changed. Migration should work automatically. Refer to the description of the options for more details. + +- The `compiz` window manager and package was removed. The system support had been broken for several years. + +- Touchpad support should now be enabled through `libinput` as `synaptics` is now deprecated. See the option `services.xserver.libinput.enable`. + +- grsecurity/PaX support has been dropped, following upstream\'s decision to cease free support. See [ upstream\'s announcement](https://grsecurity.net/passing_the_baton.php) for more information. No complete replacement for grsecurity/PaX is available presently. + +- `services.mysql` now has declarative configuration of databases and users with the `ensureDatabases` and `ensureUsers` options. + + These options will never delete existing databases and users, especially not when the value of the options are changed. + + The MySQL users will be identified using [ Unix socket authentication](https://mariadb.com/kb/en/library/authentication-plugin-unix-socket/). This authenticates the Unix user with the same name only, and that without the need for a password. + + If you have previously created a MySQL `root` user _with a password_, you will need to add `root` user for unix socket authentication before using the new options. This can be done by running the following SQL script: + + ```SQL + CREATE USER 'root'@'%' IDENTIFIED BY ''; + GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION; + FLUSH PRIVILEGES; + + -- Optionally, delete the password-authenticated user: + -- DROP USER 'root'@'localhost'; + ``` + +- `services.mysqlBackup` now works by default without any user setup, including for users other than `mysql`. + + By default, the `mysql` user is no longer the user which performs the backup. Instead a system account `mysqlbackup` is used. + + The `mysqlBackup` service is also now using systemd timers instead of `cron`. + + Therefore, the `services.mysqlBackup.period` option no longer exists, and has been replaced with `services.mysqlBackup.calendar`, which is in the format of [systemd.time(7)](https://www.freedesktop.org/software/systemd/man/systemd.time.html#Calendar%20Events). + + If you expect to be sent an e-mail when the backup fails, consider using a script which monitors the systemd journal for errors. Regretfully, at present there is no built-in functionality for this. + + You can check that backups still work by running `systemctl start mysql-backup` then `systemctl status mysql-backup`. + +- Templated systemd services e.g `container@name` are now handled currectly when switching to a new configuration, resulting in them being reloaded. + +- Steam: the `newStdcpp` parameter was removed and should not be needed anymore. + +- Redis has been updated to version 4 which mandates a cluster mass-restart, due to changes in the network handling, in order to ensure compatibility with networks NATing traffic. + +## Other Notable Changes {#sec-release-17.09-notable-changes} + +- Modules can now be disabled by using [ disabledModules](https://nixos.org/nixpkgs/manual/#sec-replace-modules), allowing another to take it\'s place. This can be used to import a set of modules from another channel while keeping the rest of the system on a stable release. + +- Updated to FreeType 2.7.1, including a new TrueType engine. The new engine replaces the Infinality engine which was the default in NixOS. The default font rendering settings are now provided by fontconfig-penultimate, replacing fontconfig-ultimate; the new defaults are less invasive and provide rendering that is more consistent with other systems and hopefully with each font designer\'s intent. Some system-wide configuration has been removed from the Fontconfig NixOS module where user Fontconfig settings are available. + +- ZFS/SPL have been updated to 0.7.0, `zfsUnstable, splUnstable` have therefore been removed. + +- The `time.timeZone` option now allows the value `null` in addition to timezone strings. This value allows changing the timezone of a system imperatively using `timedatectl set-timezone`. The default timezone is still UTC. + +- Nixpkgs overlays may now be specified with a file as well as a directory. The value of `<nixpkgs-overlays>` may be a file, and `~/.config/nixpkgs/overlays.nix` can be used instead of the `~/.config/nixpkgs/overlays` directory. + + See the overlays chapter of the Nixpkgs manual for more details. + +- Definitions for `/etc/hosts` can now be specified declaratively with `networking.hosts`. + +- Two new options have been added to the installer loader, in addition to the default having changed. The kernel log verbosity has been lowered to the upstream default for the default options, in order to not spam the console when e.g. joining a network. + + This therefore leads to adding a new `debug` option to set the log level to the previous verbose mode, to make debugging easier, but still accessible easily. + + Additionally a `copytoram` option has been added, which makes it possible to remove the install medium after booting. This allows tethering from your phone after booting from it. + +- `services.gitlab-runner.configOptions` has been added to specify the configuration of gitlab-runners declaratively. + +- `services.jenkins.plugins` has been added to install plugins easily, this can be generated with jenkinsPlugins2nix. + +- `services.postfix.config` has been added to specify the main.cf with NixOS options. Additionally other options have been added to the postfix module and has been improved further. + +- The GitLab package and module have been updated to the latest 10.0 release. + +- The `systemd-boot` boot loader now lists the NixOS version, kernel version and build date of all bootable generations. + +- The dnscrypt-proxy service now defaults to using a random upstream resolver, selected from the list of public non-logging resolvers with DNSSEC support. Existing configurations can be migrated to this mode of operation by omitting the `services.dnscrypt-proxy.resolverName` option or setting it to `"random"`. diff --git a/nixos/doc/manual/release-notes/rl-1803.section.md b/nixos/doc/manual/release-notes/rl-1803.section.md new file mode 100644 index 00000000000..e4e46798104 --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-1803.section.md @@ -0,0 +1,284 @@ +# Release 18.03 ("Impala", 2018/04/04) {#sec-release-18.03} + +## Highlights {#sec-release-18.03-highlights} + +In addition to numerous new and upgraded packages, this release has the following highlights: + +- End of support is planned for end of October 2018, handing over to 18.09. + +- Platform support: x86_64-linux and x86_64-darwin since release time (the latter isn\'t NixOS, really).

This was already true for string-valued options in the previous release, but not for list-valued options. If you need to pass literal dollar signs through Postfix, double them. + +- The `postage` package (for web-based PostgreSQL administration) has been renamed to `pgmanage`. The corresponding module has also been renamed. To migrate please rename all `services.postage` options to `services.pgmanage`. + +- Package attributes starting with a digit have been prefixed with an underscore sign.

To re-enable support, add `PubkeyAcceptedKeyTypes +ssh-dss` to the end of your `services.openssh.extraConfig`. + + After updating the keys to be stronger, anyone still on a pre-17.03 version is safe to jump to 17.03, as vetted [here](https://search.nix.gsc.io/?q=stateVersion). + +- The `openssh` package now includes Kerberos support by default; the `openssh_with_kerberos` package is now a deprecated alias. If you do not want Kerberos support, you can do `openssh.override { withKerberos = false; }`. Note, this also applies to the `openssh_hpn` package. + +- `cc-wrapper` has been split in two; there is now also a `bintools-wrapper`. The most commonly used files in `nix-support` are now split between the two wrappers. Some commonly used ones, like `nix-support/dynamic-linker`, are duplicated for backwards compatability, even though they rightly belong only in `bintools-wrapper`. Other more obscure ones are just moved. + +- The propagation logic has been changed. The new logic, along with new types of dependencies that go with, is thoroughly documented in the \"Specifying dependencies\" section of the \"Standard Environment\" chapter of the nixpkgs manual. The old logic isn\'t but is easy to describe: dependencies were propagated as the same type of dependency no matter what. In practice, that means that many `propagatedNativeBuildInputs` should instead be `propagatedBuildInputs`. Thankfully, that was and is the least used type of dependency. Also, it means that some `propagatedBuildInputs` should instead be `depsTargetTargetPropagated`. Other types dependencies should be unaffected. + +- `lib.addPassthru drv passthru` is removed. Use `lib.extendDerivation true passthru drv` instead. + +- The `memcached` service no longer accept dynamic socket paths via `services.memcached.socket`. Unix sockets can be still enabled by `services.memcached.enableUnixSocket` and will be accessible at `/run/memcached/memcached.sock`. + +- The `hardware.amdHybridGraphics.disable` option was removed for lack of a maintainer. If you still need this module, you may wish to include a copy of it from an older version of nixos in your imports. + +- The merging of config options for `services.postfix.config` was buggy. Previously, if other options in the Postfix module like `services.postfix.useSrs` were set and the user set config options that were also set by such options, the resulting config wouldn\'t include all options that were needed. They are now merged correctly. If config options need to be overridden, `lib.mkForce` or `lib.mkOverride` can be used. + +- The following changes apply if the `stateVersion` is changed to 18.03 or higher. For `stateVersion = "17.09"` or lower the old behavior is preserved. + + - `matrix-synapse` uses postgresql by default instead of sqlite. Migration instructions can be found [ here ](https://github.com/matrix-org/synapse/blob/master/docs/postgres.rst#porting-from-sqlite). + +- The `jid` package has been removed, due to maintenance overhead of a go package having non-versioned dependencies. + +- When using `services.xserver.libinput` (enabled by default in GNOME), it now handles all input devices, not just touchpads. As a result, you might need to re-evaluate any custom Xorg configuration. In particular, `Option "XkbRules" "base"` may result in broken keyboard layout. + +- The `attic` package was removed. A maintained fork called [Borg](https://www.borgbackup.org/) should be used instead. Migration instructions can be found [here](http://borgbackup.readthedocs.io/en/stable/usage/upgrade.html#attic-and-borg-0-xx-to-borg-1-x). + +- The Piwik analytics software was renamed to Matomo: + + - The package `pkgs.piwik` was renamed to `pkgs.matomo`. + + - The service `services.piwik` was renamed to `services.matomo`. + + - The data directory `/var/lib/piwik` was renamed to `/var/lib/matomo`. All files will be moved automatically on first startup, but you might need to adjust your backup scripts. + + - The default `serverName` for the nginx configuration changed from `piwik.${config.networking.hostName}` to `matomo.${config.networking.hostName}.${config.networking.domain}` if `config.networking.domain` is set, `matomo.${config.networking.hostName}` if it is not set. If you change your `serverName`, remember you\'ll need to update the `trustedHosts[]` array in `/var/lib/matomo/config/config.ini.php` as well. + + - The `piwik` user was renamed to `matomo`. The service will adjust ownership automatically for files in the data directory. If you use unix socket authentication, remember to give the new `matomo` user access to the database and to change the `username` to `matomo` in the `[database]` section of `/var/lib/matomo/config/config.ini.php`. + + - If you named your database \`piwik\`, you might want to rename it to \`matomo\` to keep things clean, but this is neither enforced nor required. + +- `nodejs-4_x` is end-of-life. `nodejs-4_x`, `nodejs-slim-4_x` and `nodePackages_4_x` are removed. + +- The `pump.io` NixOS module was removed. It is now maintained as an [external module](https://github.com/rvl/pump.io-nixos). + +- The Prosody XMPP server has received a major update. The following modules were renamed: + + - `services.prosody.modules.httpserver` is now `services.prosody.modules.http_files` + + - `services.prosody.modules.console` is now `services.prosody.modules.admin_telnet` + + Many new modules are now core modules, most notably `services.prosody.modules.carbons` and `services.prosody.modules.mam`. + + The better-performing `libevent` backend is now enabled by default. + + `withCommunityModules` now passes through the modules to `services.prosody.extraModules`. Use `withOnlyInstalledCommunityModules` for modules that should not be enabled directly, e.g `lib_ldap`. + +- All prometheus exporter modules are now defined as submodules. The exporters are configured using `services.prometheus.exporters`. + +## Other Notable Changes {#sec-release-18.03-notable-changes} + +- ZNC option `services.znc.mutable` now defaults to `true`. That means that old configuration is not overwritten by default when update to the znc options are made. + +- The option `networking.wireless.networks.<name>.auth` has been added for wireless networks with WPA-Enterprise authentication. There is also a new `extraConfig` option to directly configure `wpa_supplicant` and `hidden` to connect to hidden networks. + +- In the module `networking.interfaces.<name>` the following options have been removed: + + - `ipAddress` + + - `ipv6Address` + + - `prefixLength` + + - `ipv6PrefixLength` + + - `subnetMask` + + To assign static addresses to an interface the options `ipv4.addresses` and `ipv6.addresses` should be used instead. The options `ip4` and `ip6` have been renamed to `ipv4.addresses` `ipv6.addresses` respectively. The new options `ipv4.routes` and `ipv6.routes` have been added to set up static routing. + +- The option `services.logstash.listenAddress` is now `127.0.0.1` by default. Previously the default behaviour was to listen on all interfaces. + +- `services.btrfs.autoScrub` has been added, to periodically check btrfs filesystems for data corruption. If there\'s a correct copy available, it will automatically repair corrupted blocks. + +- `displayManager.lightdm.greeters.gtk.clock-format.` has been added, the clock format string (as expected by strftime, e.g. `%H:%M`) to use with the lightdm gtk greeter panel. + + If set to null the default clock format is used. + +- `displayManager.lightdm.greeters.gtk.indicators` has been added, a list of allowed indicator modules to use with the lightdm gtk greeter panel. + + Built-in indicators include `~a11y`, `~language`, `~session`, `~power`, `~clock`, `~host`, `~spacer`. Unity indicators can be represented by short name (e.g. `sound`, `power`), service file name, or absolute path. + + If set to `null` the default indicators are used. + + In order to have the previous default configuration add + + ```nix + { + services.xserver.displayManager.lightdm.greeters.gtk.indicators = [ + "~host" "~spacer" + "~clock" "~spacer" + "~session" + "~language" + "~a11y" + "~power" + ]; + } + ``` + + to your `configuration.nix`. + +- The NixOS test driver supports user services declared by `systemd.user.services`. The methods `waitForUnit`, `getUnitInfo`, `startJob` and `stopJob` provide an optional `$user` argument for that purpose. + +- Enabling bash completion on NixOS, `programs.bash.enableCompletion`, will now also enable completion for the Nix command line tools by installing the [nix-bash-completions](https://github.com/hedning/nix-bash-completions) package. diff --git a/nixos/doc/manual/release-notes/rl-1809.section.md b/nixos/doc/manual/release-notes/rl-1809.section.md new file mode 100644 index 00000000000..3443db37c97 --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-1809.section.md @@ -0,0 +1,332 @@ +# Release 18.09 ("Jellyfish", 2018/10/05) {#sec-release-18.09} + +## Highlights {#sec-release-18.09-highlights} + +In addition to numerous new and upgraded packages, this release has the following notable updates: + +- End of support is planned for end of April 2019, handing over to 19.03. + +- Platform support: x86_64-linux and x86_64-darwin as always. Support for aarch64-linux is as with the previous releases, not equivalent to the x86-64-linux release, but with efforts to reach parity. + +- Nix has been updated to 2.1; see its [release notes](https://nixos.org/nix/manual/#ssec-relnotes-2.1). + +- Core versions: linux: 4.14 LTS (unchanged), glibc: 2.26 → 2.27, gcc: 7 (unchanged), systemd: 237 → 239. + +- Desktop version changes: gnome: 3.26 → 3.28, (KDE) plasma-desktop: 5.12 → 5.13. + +Notable changes and additions for 18.09 include: + +- Support for wrapping binaries using `firejail` has been added through `programs.firejail.wrappedBinaries`. + + For example + + ```nix + { + programs.firejail = { + enable = true; + wrappedBinaries = { + firefox = "${lib.getBin pkgs.firefox}/bin/firefox"; + mpv = "${lib.getBin pkgs.mpv}/bin/mpv"; + }; + }; + } + ``` + + This will place `firefox` and `mpv` binaries in the global path wrapped by firejail. + +- User channels are now in the default `NIX_PATH`, allowing users to use their personal `nix-channel` defined channels in `nix-build` and `nix-shell` commands, as well as in imports like `import <mychannel>`. + + For example + + ```ShellSession + $ nix-channel --add https://nixos.org/channels/nixpkgs-unstable nixpkgsunstable + $ nix-channel --update + $ nix-build '<nixpkgsunstable>' -A gitFull + $ nix run -f '<nixpkgsunstable>' gitFull + $ nix-instantiate -E '(import <nixpkgsunstable> {}).gitFull' + ``` + +## New Services {#sec-release-18.09-new-services} + +A curated selection of new services that were added since the last release: + +- The `services.cassandra` module has been reworked and was rewritten from scratch. The service has succeeding tests for the versions 2.1, 2.2, 3.0 and 3.11 of [Apache Cassandra](https://cassandra.apache.org/). + +- There is a new `services.foundationdb` module for deploying [FoundationDB](https://www.foundationdb.org) clusters. + +- When enabled the `iproute2` will copy the files expected by ip route (e.g., `rt_tables`) in `/etc/iproute2`. This allows to write aliases for routing tables for instance. + +- `services.strongswan-swanctl` is a modern replacement for `services.strongswan`. You can use either one of them to setup IPsec VPNs but not both at the same time. + + `services.strongswan-swanctl` uses the [swanctl](https://wiki.strongswan.org/projects/strongswan/wiki/swanctl) command which uses the modern [vici](https://github.com/strongswan/strongswan/blob/master/src/libcharon/plugins/vici/README.md) _Versatile IKE Configuration Interface_. The deprecated `ipsec` command used in `services.strongswan` is using the legacy [stroke configuration interface](https://github.com/strongswan/strongswan/blob/master/README_LEGACY.md). + +- The new `services.elasticsearch-curator` service periodically curates or manages, your Elasticsearch indices and snapshots. + +Every new services: + +- `./config/xdg/autostart.nix` + +- `./config/xdg/icons.nix` + +- `./config/xdg/menus.nix` + +- `./config/xdg/mime.nix` + +- `./hardware/brightnessctl.nix` + +- `./hardware/onlykey.nix` + +- `./hardware/video/uvcvideo/default.nix` + +- `./misc/documentation.nix` + +- `./programs/firejail.nix` + +- `./programs/iftop.nix` + +- `./programs/sedutil.nix` + +- `./programs/singularity.nix` + +- `./programs/xss-lock.nix` + +- `./programs/zsh/zsh-autosuggestions.nix` + +- `./services/admin/oxidized.nix` + +- `./services/backup/duplicati.nix` + +- `./services/backup/restic.nix` + +- `./services/backup/restic-rest-server.nix` + +- `./services/cluster/hadoop/default.nix` + +- `./services/databases/aerospike.nix` + +- `./services/databases/monetdb.nix` + +- `./services/desktops/bamf.nix` + +- `./services/desktops/flatpak.nix` + +- `./services/desktops/zeitgeist.nix` + +- `./services/development/bloop.nix` + +- `./services/development/jupyter/default.nix` + +- `./services/hardware/lcd.nix` + +- `./services/hardware/undervolt.nix` + +- `./services/misc/clipmenu.nix` + +- `./services/misc/gitweb.nix` + +- `./services/misc/serviio.nix` + +- `./services/misc/safeeyes.nix` + +- `./services/misc/sysprof.nix` + +- `./services/misc/weechat.nix` + +- `./services/monitoring/datadog-agent.nix` + +- `./services/monitoring/incron.nix` + +- `./services/networking/dnsdist.nix` + +- `./services/networking/freeradius.nix` + +- `./services/networking/hans.nix` + +- `./services/networking/morty.nix` + +- `./services/networking/ndppd.nix` + +- `./services/networking/ocserv.nix` + +- `./services/networking/owamp.nix` + +- `./services/networking/quagga.nix` + +- `./services/networking/shadowsocks.nix` + +- `./services/networking/stubby.nix` + +- `./services/networking/zeronet.nix` + +- `./services/security/certmgr.nix` + +- `./services/security/cfssl.nix` + +- `./services/security/oauth2_proxy_nginx.nix` + +- `./services/web-apps/virtlyst.nix` + +- `./services/web-apps/youtrack.nix` + +- `./services/web-servers/hitch/default.nix` + +- `./services/web-servers/hydron.nix` + +- `./services/web-servers/meguca.nix` + +- `./services/web-servers/nginx/gitweb.nix` + +- `./virtualisation/kvmgt.nix` + +- `./virtualisation/qemu-guest-agent.nix` + +## Backward Incompatibilities {#sec-release-18.09-incompatibilities} + +When upgrading from a previous release, please be aware of the following incompatible changes: + +- Some licenses that were incorrectly not marked as unfree now are.

(See above.) + +- `lib.strict` is removed. Use `builtins.seq` instead. + +- The `clementine` package points now to the free derivation. `clementineFree` is removed now and `clementineUnfree` points to the package which is bundled with the unfree `libspotify` package. + +- The `netcat` package is now taken directly from OpenBSD\'s `libressl`, instead of relying on Debian\'s fork. The new version should be very close to the old version, but there are some minor differences. Importantly, flags like -b, -q, -C, and -Z are no longer accepted by the nc command. + +- The `services.docker-registry.extraConfig` object doesn\'t contain environment variables anymore. Instead it needs to provide an object structure that can be mapped onto the YAML configuration defined in [the `docker/distribution` docs](https://github.com/docker/distribution/blob/v2.6.2/docs/configuration.md). + +- `gnucash` has changed from version 2.4 to 3.x. If you\'ve been using `gnucash` (version 2.4) instead of `gnucash26` (version 2.6) you must open your Gnucash data file(s) with `gnucash26` and then save them to upgrade the file format. Then you may use your data file(s) with Gnucash 3.x. See the upgrade [documentation](https://wiki.gnucash.org/wiki/FAQ#Using_Different_Versions.2C_Up_And_Downgrade). Gnucash 2.4 is still available under the attribute `gnucash24`. + +- `services.munge` now runs as user (and group) `munge` instead of root. Make sure the key file is accessible to the daemon. + +- `dockerTools.buildImage` now uses `null` as default value for `tag`, which indicates that the nix output hash will be used as tag. + +- The ELK stack: `elasticsearch`, `logstash` and `kibana` has been upgraded from 2.\* to 6.3.\*. The 2.\* versions have been [unsupported since last year](https://www.elastic.co/support/eol) so they have been removed. You can still use the 5.\* versions under the names `elasticsearch5`, `logstash5` and `kibana5`. + + The elastic beats: `filebeat`, `heartbeat`, `metricbeat` and `packetbeat` have had the same treatment: they now target 6.3.\* as well. The 5.\* versions are available under the names: `filebeat5`, `heartbeat5`, `metricbeat5` and `packetbeat5` + + The ELK-6.3 stack now comes with [X-Pack by default](https://www.elastic.co/products/x-pack/open). Since X-Pack is licensed under the [Elastic License](https://github.com/elastic/elasticsearch/blob/master/licenses/ELASTIC-LICENSE.txt) the ELK packages now have an unfree license. To use them you need to specify `allowUnfree = true;` in your nixpkgs configuration. + + Fortunately there is also a free variant of the ELK stack without X-Pack. The packages are available under the names: `elasticsearch-oss`, `logstash-oss` and `kibana-oss`. + +- Options `boot.initrd.luks.devices.name.yubikey.ramfsMountPoint` `boot.initrd.luks.devices.name.yubikey.storage.mountPoint` were removed. `luksroot.nix` module never supported more than one YubiKey at a time anyway, hence those options never had any effect. You should be able to remove them from your config without any issues. + +- `stdenv.system` and `system` in nixpkgs now refer to the host platform instead of the build platform. For native builds this is not change, let alone a breaking one. For cross builds, it is a breaking change, and `stdenv.buildPlatform.system` can be used instead for the old behavior. They should be using that anyways for clarity. + +- Groups `kvm` and `render` are introduced now, as systemd requires them. + +## Other Notable Changes {#sec-release-18.09-notable-changes} + +- `dockerTools.pullImage` relies on image digest instead of image tag to download the image. The `sha256` of a pulled image has to be updated. + +- `lib.attrNamesToStr` has been deprecated. Use more specific concatenation (`lib.concat(Map)StringsSep`) instead. + +- `lib.addErrorContextToAttrs` has been deprecated. Use `builtins.addErrorContext` directly. + +- `lib.showVal` has been deprecated. Use `lib.traceSeqN` instead. + +- `lib.traceXMLVal` has been deprecated. Use `lib.traceValFn builtins.toXml` instead. + +- `lib.traceXMLValMarked` has been deprecated. Use `lib.traceValFn (x: str + builtins.toXML x)` instead. + +- The `pkgs` argument to NixOS modules can now be set directly using `nixpkgs.pkgs`. Previously, only the `system`, `config` and `overlays` arguments could be used to influence `pkgs`. + +- A NixOS system can now be constructed more easily based on a preexisting invocation of Nixpkgs. For example: + + ```nix + { + inherit (pkgs.nixos { + boot.loader.grub.enable = false; + fileSystems."/".device = "/dev/xvda1"; + }) toplevel kernel initialRamdisk manual; + } + ``` + + This benefits evaluation performance, lets you write Nixpkgs packages that depend on NixOS images and is consistent with a deployment architecture that would be centered around Nixpkgs overlays. + +- `lib.traceValIfNot` has been deprecated. Use `if/then/else` and `lib.traceValSeq` instead. + +- `lib.traceCallXml` has been deprecated. Please complain if you use the function regularly. + +- The attribute `lib.nixpkgsVersion` has been deprecated in favor of `lib.version`. Please refer to the discussion in [NixOS/nixpkgs\#39416](https://github.com/NixOS/nixpkgs/pull/39416#discussion_r183845745) for further reference. + +- `lib.recursiveUpdateUntil` was not acting according to its specification. It has been fixed to act according to the docstring, and a test has been added. + +- The module for `security.dhparams` has two new options now: + + `security.dhparams.stateless` + + : Puts the generated Diffie-Hellman parameters into the Nix store instead of managing them in a stateful manner in `/var/lib/dhparams`. + + `security.dhparams.defaultBitSize` + + : The default bit size to use for the generated Diffie-Hellman parameters. + + ::: {.note} + The path to the actual generated parameter files should now be queried using `config.security.dhparams.params.name.path` because it might be either in the Nix store or in a directory configured by `security.dhparams.path`. + ::: + + ::: {.note} + **For developers:** + + Module implementers should not set a specific bit size in order to let users configure it by themselves if they want to have a different bit size than the default (2048). + + An example usage of this would be: + + ```nix + { config, ... }: + + { + security.dhparams.params.myservice = {}; + environment.etc."myservice.conf".text = '' + dhparams = ${config.security.dhparams.params.myservice.path} + ''; + } + ``` + + ::: + +- `networking.networkmanager.useDnsmasq` has been deprecated. Use `networking.networkmanager.dns` instead. + +- The Kubernetes package has been bumped to major version 1.11. Please consult the [release notes](https://github.com/kubernetes/kubernetes/blob/release-1.11/CHANGELOG-1.11.md) for details on new features and api changes. + +- The option `services.kubernetes.apiserver.admissionControl` was renamed to `services.kubernetes.apiserver.enableAdmissionPlugins`. + +- Recommended way to access the Kubernetes Dashboard is via HTTPS (TLS) Therefore; public service port for the dashboard has changed to 443 (container port 8443) and scheme to https. + +- The option `services.kubernetes.apiserver.address` was renamed to `services.kubernetes.apiserver.bindAddress`. Note that the default value has changed from 127.0.0.1 to 0.0.0.0. + +- The option `services.kubernetes.apiserver.publicAddress` was not used and thus has been removed. + +- The option `services.kubernetes.addons.dashboard.enableRBAC` was renamed to `services.kubernetes.addons.dashboard.rbac.enable`. + +- The Kubernetes Dashboard now has only minimal RBAC permissions by default. If dashboard cluster-admin rights are desired, set `services.kubernetes.addons.dashboard.rbac.clusterAdmin` to true. On existing clusters, in order for the revocation of privileges to take effect, the current ClusterRoleBinding for kubernetes-dashboard must be manually removed: `kubectl delete clusterrolebinding kubernetes-dashboard` + +- The `programs.screen` module provides allows to configure `/etc/screenrc`, however the module behaved fairly counterintuitive as the config exists, but the package wasn\'t available. Since 18.09 `pkgs.screen` will be added to `environment.systemPackages`. + +- The module `services.networking.hostapd` now uses WPA2 by default. + +- `s6Dns`, `s6Networking`, `s6LinuxUtils` and `s6PortableUtils` renamed to `s6-dns`, `s6-networking`, `s6-linux-utils` and `s6-portable-utils` respectively. + +- The module option `nix.useSandbox` is now defaulted to `true`. + +- The config activation script of `nixos-rebuild` now [reloads](https://www.freedesktop.org/software/systemd/man/systemctl.html#Manager%20Lifecycle%20Commands) all user units for each authenticated user. + +- The default display manager is now LightDM. To use SLiM set `services.xserver.displayManager.slim.enable` to `true`. + +- NixOS option descriptions are now automatically broken up into individual paragraphs if the text contains two consecutive newlines, so it\'s no longer necessary to use `</para><para>` to start a new paragraph. + +- Top-level `buildPlatform`, `hostPlatform`, and `targetPlatform` in Nixpkgs are deprecated. Please use their equivalents in `stdenv` instead: `stdenv.buildPlatform`, `stdenv.hostPlatform`, and `stdenv.targetPlatform`. diff --git a/nixos/doc/manual/release-notes/rl-1903.section.md b/nixos/doc/manual/release-notes/rl-1903.section.md new file mode 100644 index 00000000000..7637a70c1bf --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-1903.section.md @@ -0,0 +1,214 @@ +# Release 19.03 ("Koi", 2019/04/11) {#sec-release-19.03} + +## Highlights {#sec-release-19.03-highlights} + +In addition to numerous new and upgraded packages, this release has the following highlights: + +- End of support is planned for end of October 2019, handing over to 19.09. + +- The default Python 3 interpreter is now CPython 3.7 instead of CPython 3.6. + +- Added the Pantheon desktop environment. It can be enabled through `services.xserver.desktopManager.pantheon.enable`. + + ::: {.note} + By default, `services.xserver.desktopManager.pantheon` enables LightDM as a display manager, as pantheon\'s screen locking implementation relies on it. + Because of that it is recommended to leave LightDM enabled. If you\'d like to disable it anyway, set `services.xserver.displayManager.lightdm.enable` to `false` and enable your preferred display manager. + ::: + + Also note that Pantheon\'s LightDM greeter is not enabled by default, because it has numerous issues in NixOS and isn\'t optimal for use here yet. + +- A major refactoring of the Kubernetes module has been completed. Refactorings primarily focus on decoupling components and enhancing security. Two-way TLS and RBAC has been enabled by default for all components, which slightly changes the way the module is configured. See: [](#sec-kubernetes) for details. + +- There is now a set of `confinement` options for `systemd.services`, which allows to restrict services into a chroot 2 ed environment that only contains the store paths from the runtime closure of the service. + +## New Services {#sec-release-19.03-new-services} + +The following new services were added since the last release: + +- `./programs/nm-applet.nix` + +- There is a new `security.googleOsLogin` module for using [OS Login](https://cloud.google.com/compute/docs/instances/managing-instance-access) to manage SSH access to Google Compute Engine instances, which supersedes the imperative and broken `google-accounts-daemon` used in `nixos/modules/virtualisation/google-compute-config.nix`. + +- `./services/misc/beanstalkd.nix` + +- There is a new `services.cockroachdb` module for running CockroachDB databases. NixOS now ships with CockroachDB 2.1.x as well, available on `x86_64-linux` and `aarch64-linux`. + +- `./security/duosec.nix` + +- The [PAM module for Duo Security](https://duo.com/docs/duounix) has been enabled for use. One can configure it using the `security.duosec` options along with the corresponding PAM option in `security.pam.services.<name?>.duoSecurity.enable`. + +## Backward Incompatibilities {#sec-release-19.03-incompatibilities} + +When upgrading from a previous release, please be aware of the following incompatible changes: + +- The minimum version of Nix required to evaluate Nixpkgs is now 2.0. + + - For users of NixOS 18.03 and 19.03, NixOS defaults to Nix 2.0, but supports using Nix 1.11 by setting `nix.package = pkgs.nix1;`. If this option is set to a Nix 1.11 package, you will need to either unset the option or upgrade it to Nix 2.0. + + - For users of NixOS 17.09, you will first need to upgrade Nix by setting `nix.package = pkgs.nixStable2;` and run `nixos-rebuild switch` as the `root` user. + + - For users of a daemon-less Nix installation on Linux or macOS, you can upgrade Nix by running `curl -L https://nixos.org/nix/install | sh`, or prior to doing a channel update, running `nix-env -iA nix`. If you have already run a channel update and Nix is no longer able to evaluate Nixpkgs, the error message printed should provide adequate directions for upgrading Nix. + + - For users of the Nix daemon on macOS, you can upgrade Nix by running `sudo -i sh -c 'nix-channel --update && nix-env -iA nixpkgs.nix'; sudo launchctl stop org.nixos.nix-daemon; sudo launchctl start org.nixos.nix-daemon`. + +- The `buildPythonPackage` function now sets `strictDeps = true` to help distinguish between native and non-native dependencies in order to improve cross-compilation compatibility. Note however that this may break user expressions. + +- The `buildPythonPackage` function now sets `LANG = C.UTF-8` to enable Unicode support. The `glibcLocales` package is no longer needed as a build input. + +- The Syncthing state and configuration data has been moved from `services.syncthing.dataDir` to the newly defined `services.syncthing.configDir`, which default to `/var/lib/syncthing/.config/syncthing`. This change makes possible to share synced directories using ACLs without Syncthing resetting the permission on every start. + +- The `ntp` module now has sane default restrictions. If you\'re relying on the previous defaults, which permitted all queries and commands from all firewall-permitted sources, you can set `services.ntp.restrictDefault` and `services.ntp.restrictSource` to `[]`. + +- Package `rabbitmq_server` is renamed to `rabbitmq-server`. + +- The `light` module no longer uses setuid binaries, but udev rules. As a consequence users of that module have to belong to the `video` group in order to use the executable (i.e. `users.users.yourusername.extraGroups = ["video"];`). + +- Buildbot now supports Python 3 and its packages have been moved to `pythonPackages`. The options `services.buildbot-master.package` and `services.buildbot-worker.package` can be used to select the Python 2 or 3 version of the package. + +- Options `services.znc.confOptions.networks.name.userName` and `services.znc.confOptions.networks.name.modulePackages` were removed. They were never used for anything and can therefore safely be removed. + +- Package `wasm` has been renamed `proglodyte-wasm`. The package `wasm` will be pointed to `ocamlPackages.wasm` in 19.09, so make sure to update your configuration if you want to keep `proglodyte-wasm` + +- When the `nixpkgs.pkgs` option is set, NixOS will no longer ignore the `nixpkgs.overlays` option. The old behavior can be recovered by setting `nixpkgs.overlays = lib.mkForce [];`. + +- OpenSMTPD has been upgraded to version 6.4.0p1. This release makes backwards-incompatible changes to the configuration file format. See `man smtpd.conf` for more information on the new file format. + +- The versioned `postgresql` have been renamed to use underscore number seperators. For example, `postgresql96` has been renamed to `postgresql_9_6`. + +- Package `consul-ui` and passthrough `consul.ui` have been removed. The package `consul` now uses upstream releases that vendor the UI into the binary. See [\#48714](https://github.com/NixOS/nixpkgs/pull/48714#issuecomment-433454834) for details. + +- Slurm introduces the new option `services.slurm.stateSaveLocation`, which is now set to `/var/spool/slurm` by default (instead of `/var/spool`). Make sure to move all files to the new directory or to set the option accordingly. + + The slurmctld now runs as user `slurm` instead of `root`. If you want to keep slurmctld running as `root`, set `services.slurm.user = root`. + + The options `services.slurm.nodeName` and `services.slurm.partitionName` are now sets of strings to correctly reflect that fact that each of these options can occour more than once in the configuration. + +- The `solr` package has been upgraded from 4.10.3 to 7.5.0 and has undergone some major changes. The `services.solr` module has been updated to reflect these changes. Please review http://lucene.apache.org/solr/ carefully before upgrading. + +- Package `ckb` is renamed to `ckb-next`, and options `hardware.ckb.*` are renamed to `hardware.ckb-next.*`. + +- The option `services.xserver.displayManager.job.logToFile` which was previously set to `true` when using the display managers `lightdm`, `sddm` or `xpra` has been reset to the default value (`false`). + +- Network interface indiscriminate NixOS firewall options (`networking.firewall.allow*`) are now preserved when also setting interface specific rules such as `networking.firewall.interfaces.en0.allow*`. These rules continue to use the pseudo device \"default\" (`networking.firewall.interfaces.default.*`), and assigning to this pseudo device will override the (`networking.firewall.allow*`) options. + +- The `nscd` service now disables all caching of `passwd` and `group` databases by default. This was interferring with the correct functioning of the `libnss_systemd.so` module which is used by `systemd` to manage uids and usernames in the presence of `DynamicUser=` in systemd services. This was already the default behaviour in presence of `services.sssd.enable = true` because nscd caching would interfere with `sssd` in unpredictable ways as well. Because we\'re using nscd not for caching, but for convincing glibc to find NSS modules in the nix store instead of an absolute path, we have decided to disable caching globally now, as it\'s usually not the behaviour the user wants and can lead to surprising behaviour. Furthermore, negative caching of host lookups is also disabled now by default. This should fix the issue of dns lookups failing in the presence of an unreliable network. + + If the old behaviour is desired, this can be restored by setting the `services.nscd.config` option with the desired caching parameters. + + ```nix + { + services.nscd.config = + '' + server-user nscd + threads 1 + paranoia no + debug-level 0 + + enable-cache passwd yes + positive-time-to-live passwd 600 + negative-time-to-live passwd 20 + suggested-size passwd 211 + check-files passwd yes + persistent passwd no + shared passwd yes + + enable-cache group yes + positive-time-to-live group 3600 + negative-time-to-live group 60 + suggested-size group 211 + check-files group yes + persistent group no + shared group yes + + enable-cache hosts yes + positive-time-to-live hosts 600 + negative-time-to-live hosts 5 + suggested-size hosts 211 + check-files hosts yes + persistent hosts no + shared hosts yes + ''; + } + ``` + + See [\#50316](https://github.com/NixOS/nixpkgs/pull/50316) for details. + +- GitLab Shell previously used the nix store paths for the `gitlab-shell` command in its `authorized_keys` file, which might stop working after garbage collection. To circumvent that, we regenerated that file on each startup. As `gitlab-shell` has now been changed to use `/var/run/current-system/sw/bin/gitlab-shell`, this is not necessary anymore, but there might be leftover lines with a nix store path. Regenerate the `authorized_keys` file via `sudo -u git -H gitlab-rake gitlab:shell:setup` in that case. + +- The `pam_unix` account module is now loaded with its control field set to `required` instead of `sufficient`, so that later PAM account modules that might do more extensive checks are being executed. Previously, the whole account module verification was exited prematurely in case a nss module provided the account name to `pam_unix`. The LDAP and SSSD NixOS modules already add their NSS modules when enabled. In case your setup breaks due to some later PAM account module previosuly shadowed, or failing NSS lookups, please file a bug. You can get back the old behaviour by manually setting `security.pam.services.<name?>.text`. + +- The `pam_unix` password module is now loaded with its control field set to `sufficient` instead of `required`, so that password managed only by later PAM password modules are being executed. Previously, for example, changing an LDAP account\'s password through PAM was not possible: the whole password module verification was exited prematurely by `pam_unix`, preventing `pam_ldap` to manage the password as it should. + +- `fish` has been upgraded to 3.0. It comes with a number of improvements and backwards incompatible changes. See the `fish` [release notes](https://github.com/fish-shell/fish-shell/releases/tag/3.0.0) for more information. + +- The ibus-table input method has had a change in config format, which causes all previous settings to be lost. See [this commit message](https://github.com/mike-fabian/ibus-table/commit/f9195f877c5212fef0dfa446acb328c45ba5852b) for details. + +- NixOS module system type `types.optionSet` and `lib.mkOption` argument `options` are deprecated. Use `types.submodule` instead. ([\#54637](https://github.com/NixOS/nixpkgs/pull/54637)) + +- `matrix-synapse` has been updated to version 0.99. It will [no longer generate a self-signed certificate on first launch](https://github.com/matrix-org/synapse/pull/4509) and will be [the last version to accept self-signed certificates](https://matrix.org/blog/2019/02/05/synapse-0-99-0/). As such, it is now recommended to use a proper certificate verified by a root CA (for example Let\'s Encrypt). The new [manual chapter on Matrix](#module-services-matrix) contains a working example of using nginx as a reverse proxy in front of `matrix-synapse`, using Let\'s Encrypt certificates. + +- `mailutils` now works by default when `sendmail` is not in a setuid wrapper. As a consequence, the `sendmailPath` argument, having lost its main use, has been removed. + +- `graylog` has been upgraded from version 2.\* to 3.\*. Some setups making use of extraConfig (especially those exposing Graylog via reverse proxies) need to be updated as upstream removed/replaced some settings. See [Upgrading Graylog](http://docs.graylog.org/en/3.0/pages/upgrade/graylog-3.0.html#simplified-http-interface-configuration) for details. + +- The option `users.ldap.bind.password` was renamed to `users.ldap.bind.passwordFile`, and needs to be readable by the `nslcd` user. Same applies to the new `users.ldap.daemon.rootpwmodpwFile` option. + +- `nodejs-6_x` is end-of-life. `nodejs-6_x`, `nodejs-slim-6_x` and `nodePackages_6_x` are removed. + +## Other Notable Changes {#sec-release-19.03-notable-changes} + +- The `services.matomo` module gained the option `services.matomo.package` which determines the used Matomo version. + + The Matomo module now also comes with the systemd service `matomo-archive-processing.service` and a timer that automatically triggers archive processing every hour. This means that you can safely [ disable browser triggers for Matomo archiving ](https://matomo.org/docs/setup-auto-archiving/#disable-browser-triggers-for-matomo-archiving-and-limit-matomo-reports-to-updating-every-hour) at `Administration > System > General Settings`. + + Additionally, you can enable to [ delete old visitor logs ](https://matomo.org/docs/privacy/#step-2-delete-old-visitors-logs) at `Administration > System > Privacy`, but make sure that you run `systemctl start matomo-archive-processing.service` at least once without errors if you have already collected data before, so that the reports get archived before the source data gets deleted. + +- `composableDerivation` along with supporting library functions has been removed. + +- The deprecated `truecrypt` package has been removed and `truecrypt` attribute is now an alias for `veracrypt`. VeraCrypt is backward-compatible with TrueCrypt volumes. Note that `cryptsetup` also supports loading TrueCrypt volumes. + +- The Kubernetes DNS addons, kube-dns, has been replaced with CoreDNS. This change is made in accordance with Kubernetes making CoreDNS the official default starting from [Kubernetes v1.11](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.11.md#sig-cluster-lifecycle). Please beware that upgrading DNS-addon on existing clusters might induce minor downtime while the DNS-addon terminates and re-initializes. Also note that the DNS-service now runs with 2 pod replicas by default. The desired number of replicas can be configured using: `services.kubernetes.addons.dns.replicas`. + +- The quassel-webserver package and module was removed from nixpkgs due to the lack of maintainers. + +- The manual gained a [ new chapter on self-hosting `matrix-synapse` and `riot-web` ](#module-services-matrix), the most prevalent server and client implementations for the [Matrix](https://matrix.org/) federated communication network. + +- The astah-community package was removed from nixpkgs due to it being discontinued and the downloads not being available anymore. + +- The httpd service now saves log files with a .log file extension by default for easier integration with the logrotate service. + +- The owncloud server packages and httpd subservice module were removed from nixpkgs due to the lack of maintainers. + +- It is possible now to uze ZRAM devices as general purpose ephemeral block devices, not only as swap. Using more than 1 device as ZRAM swap is no longer recommended, but is still possible by setting `zramSwap.swapDevices` explicitly. + + ZRAM algorithm can be changed now. + + Changes to ZRAM algorithm are applied during `nixos-rebuild switch`, so make sure you have enough swap space on disk to survive ZRAM device rebuild. Alternatively, use `nixos-rebuild boot; reboot`. + +- Flat volumes are now disabled by default in `hardware.pulseaudio`. This has been done to prevent applications, which are unaware of this feature, setting their volumes to 100% on startup causing harm to your audio hardware and potentially your ears. + + ::: {.note} + With this change application specific volumes are relative to the master volume which can be adjusted independently, whereas before they were absolute; meaning that in effect, it scaled the device-volume with the volume of the loudest application. + ::: + +- The [`ndppd`](https://github.com/DanielAdolfsson/ndppd) module now supports [all config options](options.html#opt-services.ndppd.enable) provided by the current upstream version as service options. Additionally the `ndppd` package doesn\'t contain the systemd unit configuration from upstream anymore, the unit is completely configured by the NixOS module now. + +- New installs of NixOS will default to the Redmine 4.x series unless otherwise specified in `services.redmine.package` while existing installs of NixOS will default to the Redmine 3.x series. + +- The [Grafana module](options.html#opt-services.grafana.enable) now supports declarative [datasource and dashboard](http://docs.grafana.org/administration/provisioning/) provisioning. + +- The use of insecure ports on kubernetes has been deprecated. Thus options: `services.kubernetes.apiserver.port` and `services.kubernetes.controllerManager.port` has been renamed to `.insecurePort`, and default of both options has changed to 0 (disabled). + +- Note that the default value of `services.kubernetes.apiserver.bindAddress` has changed from 127.0.0.1 to 0.0.0.0, allowing the apiserver to be accessible from outside the master node itself. If the apiserver insecurePort is enabled, it is strongly recommended to only bind on the loopback interface. See: `services.kubernetes.apiserver.insecurebindAddress`. + +- The option `services.kubernetes.apiserver.allowPrivileged` and `services.kubernetes.kubelet.allowPrivileged` now defaults to false. Disallowing privileged containers on the cluster. + +- The kubernetes module does no longer add the kubernetes package to `environment.systemPackages` implicitly. + +- The `intel` driver has been removed from the default list of [X.org video drivers](options.html#opt-services.xserver.videoDrivers). The `modesetting` driver should take over automatically, it is better maintained upstream and has less problems with advanced X11 features. This can lead to a change in the output names used by `xrandr`. Some performance regressions on some GPU models might happen. Some OpenCL and VA-API applications might also break (Beignet seems to provide OpenCL support with `modesetting` driver, too). Kernel mode setting API does not support backlight control, so `xbacklight` tool will not work; backlight level can be controlled directly via `/sys/` or with `brightnessctl`. Users who need this functionality more than multi-output XRandR are advised to add \`intel\` to \`videoDrivers\` and report an issue (or provide additional details in an existing one) + +- Openmpi has been updated to version 4.0.0, which removes some deprecated MPI-1 symbols. This may break some older applications that still rely on those symbols. An upgrade guide can be found [here](https://www.open-mpi.org/faq/?category=mpi-removed). + + The nginx package now relies on OpenSSL 1.1 and supports TLS 1.3 by default. You can set the protocols used by the nginx service using [services.nginx.sslProtocols](options.html#opt-services.nginx.sslProtocols). + +- A new subcommand `nixos-rebuild edit` was added. diff --git a/nixos/doc/manual/release-notes/rl-1909.section.md b/nixos/doc/manual/release-notes/rl-1909.section.md new file mode 100644 index 00000000000..572f1bf5a25 --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-1909.section.md @@ -0,0 +1,313 @@ +# Release 19.09 ("Loris", 2019/10/09) {#sec-release-19.09} + +## Highlights {#sec-release-19.09-highlights} + +In addition to numerous new and upgraded packages, this release has the following highlights: + +- End of support is planned for end of April 2020, handing over to 20.03. + +- Nix has been updated to 2.3; see its [release notes](https://nixos.org/nix/manual/#ssec-relnotes-2.3). + +- Core version changes: + + systemd: 239 -\> 243 + + gcc: 7 -\> 8 + + glibc: 2.27 (unchanged) + + linux: 4.19 LTS (unchanged) + + openssl: 1.0 -\> 1.1 + +- Desktop version changes: + + plasma5: 5.14 -\> 5.16 + + gnome3: 3.30 -\> 3.32 + +- PHP now defaults to PHP 7.3, updated from 7.2. + +- PHP 7.1 is no longer supported due to upstream not supporting this version for the entire lifecycle of the 19.09 release. + +- The binfmt module is now easier to use. Additional systems can be added through `boot.binfmt.emulatedSystems`. For instance, `boot.binfmt.emulatedSystems = [ "wasm32-wasi" "x86_64-windows" "aarch64-linux" ];` will set up binfmt interpreters for each of those listed systems. + +- The installer now uses a less privileged `nixos` user whereas before we logged in as root. To gain root privileges use `sudo -i` without a password. + +- We\'ve updated to Xfce 4.14, which brings a new module `services.xserver.desktopManager.xfce4-14`. If you\'d like to upgrade, please switch from the `services.xserver.desktopManager.xfce` module as it will be deprecated in a future release. They\'re incompatibilities with the current Xfce module; it doesn\'t support `thunarPlugins` and it isn\'t recommended to use `services.xserver.desktopManager.xfce` and `services.xserver.desktopManager.xfce4-14` simultaneously or to downgrade from Xfce 4.14 after upgrading. + +- The GNOME 3 desktop manager module sports an interface to enable/disable core services, applications, and optional GNOME packages like games. + + - `services.gnome3.core-os-services.enable` + + - `services.gnome3.core-shell.enable` + + - `services.gnome3.core-utilities.enable` + + - `services.gnome3.games.enable` + + With these options we hope to give users finer grained control over their systems. Prior to this change you\'d either have to manually disable options or use `environment.gnome3.excludePackages` which only excluded the optional applications. `environment.gnome3.excludePackages` is now unguarded, it can exclude any package installed with `environment.systemPackages` in the GNOME 3 module. + +- Orthogonal to the previous changes to the GNOME 3 desktop manager module, we\'ve updated all default services and applications to match as close as possible to a default reference GNOME 3 experience. + + **The following changes were enacted in `services.gnome3.core-utilities.enable`** + + - `accerciser` + + - `dconf-editor` + + - `evolution` + + - `gnome-documents` + + - `gnome-nettool` + + - `gnome-power-manager` + + - `gnome-todo` + + - `gnome-tweaks` + + - `gnome-usage` + + - `gucharmap` + + - `nautilus-sendto` + + - `vinagre` + + - `cheese` + + - `geary` + + **The following changes were enacted in `services.gnome3.core-shell.enable`** + + - `gnome-color-manager` + + - `orca` + + - `services.avahi.enable` + +## New Services {#sec-release-19.09-new-services} + +The following new services were added since the last release: + +- `./programs/dwm-status.nix` + +- The new `hardware.printers` module allows to declaratively configure CUPS printers via the `ensurePrinters` and `ensureDefaultPrinter` options. `ensurePrinters` will never delete existing printers, but will make sure that the given printers are configured as declared. + +- There is a new [services.system-config-printer.enable](options.html#opt-services.system-config-printer.enable) and [programs.system-config-printer.enable](options.html#opt-programs.system-config-printer.enable) module for the program of the same name. If you previously had `system-config-printer` enabled through some other means you should migrate to using one of these modules. + + - `services.xserver.desktopManager.plasma5` + + - `services.xserver.desktopManager.gnome3` + + - `services.xserver.desktopManager.pantheon` + + - `services.xserver.desktopManager.mate` Note Mate uses `programs.system-config-printer` as it doesn\'t use it as a service, but its graphical interface directly. + +- [services.blueman.enable](options.html#opt-services.blueman.enable) has been added. If you previously had blueman installed via `environment.systemPackages` please migrate to using the NixOS module, as this would result in an insufficiently configured blueman. + +## Backward Incompatibilities {#sec-release-19.09-incompatibilities} + +When upgrading from a previous release, please be aware of the following incompatible changes: + +- Buildbot no longer supports Python 2, as support was dropped upstream in version 2.0.0. Configurations may need to be modified to make them compatible with Python 3. + +- PostgreSQL now uses `/run/postgresql` as its socket directory instead of `/tmp`. So if you run an application like eg. Nextcloud, where you need to use the Unix socket path as the database host name, you need to change it accordingly. + +- PostgreSQL 9.4 is scheduled EOL during the 19.09 life cycle and has been removed. + +- The options `services.prometheus.alertmanager.user` and `services.prometheus.alertmanager.group` have been removed because the alertmanager service is now using systemd\'s [ DynamicUser mechanism](http://0pointer.net/blog/dynamic-users-with-systemd.html) which obviates these options. + +- The NetworkManager systemd unit was renamed back from network-manager.service to NetworkManager.service for better compatibility with other applications expecting this name. The same applies to ModemManager where modem-manager.service is now called ModemManager.service again. + +- The `services.nzbget.configFile` and `services.nzbget.openFirewall` options were removed as they are managed internally by the nzbget. The `services.nzbget.dataDir` option hadn\'t actually been used by the module for some time and so was removed as cleanup. + +- The `services.mysql.pidDir` option was removed, as it was only used by the wordpress apache-httpd service to wait for mysql to have started up. This can be accomplished by either describing a dependency on mysql.service (preferred) or waiting for the (hardcoded) `/run/mysqld/mysql.sock` file to appear. + +- The `services.emby.enable` module has been removed, see `services.jellyfin.enable` instead for a free software fork of Emby. See the Jellyfin documentation: [ Migrating from Emby to Jellyfin ](https://jellyfin.readthedocs.io/en/latest/administrator-docs/migrate-from-emby/) + +- IPv6 Privacy Extensions are now enabled by default for undeclared interfaces. The previous behaviour was quite misleading --- even though the default value for `networking.interfaces.*.preferTempAddress` was `true`, undeclared interfaces would not prefer temporary addresses. Now, interfaces not mentioned in the config will prefer temporary addresses. EUI64 addresses can still be set as preferred by explicitly setting the option to `false` for the interface in question. + +- Since Bittorrent Sync was superseded by Resilio Sync in 2016, the `bittorrentSync`, `bittorrentSync14`, and `bittorrentSync16` packages have been removed in favor of `resilio-sync`. + + The corresponding module, `services.btsync` has been replaced by the `services.resilio` module. + +- The httpd service no longer attempts to start the postgresql service. If you have come to depend on this behaviour then you can preserve the behavior with the following configuration: `systemd.services.httpd.after = [ "postgresql.service" ];` + + The option `services.httpd.extraSubservices` has been marked as deprecated. You may still use this feature, but it will be removed in a future release of NixOS. You are encouraged to convert any httpd subservices you may have written to a full NixOS module. + + Most of the httpd subservices packaged with NixOS have been replaced with full NixOS modules including LimeSurvey, WordPress, and Zabbix. These modules can be enabled using the `services.limesurvey.enable`, `services.mediawiki.enable`, `services.wordpress.enable`, and `services.zabbixWeb.enable` options. + +- The option `systemd.network.networks.<name>.routes.*.routeConfig.GatewayOnlink` was renamed to `systemd.network.networks.<name>.routes.*.routeConfig.GatewayOnLink` (capital `L`). This follows [ upstreams renaming ](https://github.com/systemd/systemd/commit/9cb8c5593443d24c19e40bfd4fc06d672f8c554c) of the setting. + +- As of this release the NixOps feature `autoLuks` is deprecated. It no longer works with our systemd version without manual intervention. + + Whenever the usage of the module is detected the evaluation will fail with a message explaining why and how to deal with the situation. + + A new knob named `nixops.enableDeprecatedAutoLuks` has been introduced to disable the eval failure and to acknowledge the notice was received and read. If you plan on using the feature please note that it might break with subsequent updates. + + Make sure you set the `_netdev` option for each of the file systems referring to block devices provided by the autoLuks module. Not doing this might render the system in a state where it doesn\'t boot anymore. + + If you are actively using the `autoLuks` module please let us know in [issue \#62211](https://github.com/NixOS/nixpkgs/issues/62211). + +- The setopt declarations will be evaluated at the end of `/etc/zshrc`, so any code in [programs.zsh.interactiveShellInit](options.html#opt-programs.zsh.interactiveShellInit), [programs.zsh.loginShellInit](options.html#opt-programs.zsh.loginShellInit) and [programs.zsh.promptInit](options.html#opt-programs.zsh.promptInit) may break if it relies on those options being set. + +- The `prometheus-nginx-exporter` package now uses the offical exporter provided by NGINX Inc. Its metrics are differently structured and are incompatible to the old ones. For information about the metrics, have a look at the [official repo](https://github.com/nginxinc/nginx-prometheus-exporter). + +- The `shibboleth-sp` package has been updated to version 3. It is largely backward compatible, for further information refer to the [release notes](https://wiki.shibboleth.net/confluence/display/SP3/ReleaseNotes) and [upgrade guide](https://wiki.shibboleth.net/confluence/display/SP3/UpgradingFromV2). + + Nodejs 8 is scheduled EOL under the lifetime of 19.09 and has been dropped. + +- By default, prometheus exporters are now run with `DynamicUser` enabled. Exporters that need a real user, now run under a seperate user and group which follow the pattern `<exporter-name>-exporter`, instead of the previous default `nobody` and `nogroup`. Only some exporters are affected by the latter, namely the exporters `dovecot`, `node`, `postfix` and `varnish`. + +- The `ibus-qt` package is not installed by default anymore when [i18n.inputMethod.enabled](options.html#opt-i18n.inputMethod.enabled) is set to `ibus`. If IBus support in Qt 4.x applications is required, add the `ibus-qt` package to your [environment.systemPackages](options.html#opt-environment.systemPackages) manually. + +- The CUPS Printing service now uses socket-based activation by default, only starting when needed. The previous behavior can be restored by setting `services.cups.startWhenNeeded` to `false`. + +- The `services.systemhealth` module has been removed from nixpkgs due to lack of maintainer. + +- The `services.mantisbt` module has been removed from nixpkgs due to lack of maintainer. + +- Squid 3 has been removed and the `squid` derivation now refers to Squid 4. + +- The `services.pdns-recursor.extraConfig` option has been replaced by `services.pdns-recursor.settings`. The new option allows setting extra configuration while being better type-checked and mergeable. + +- No service depends on `keys.target` anymore which is a systemd target that indicates if all [NixOps keys](https://nixos.org/nixops/manual/#idm140737322342384) were successfully uploaded. Instead, `<key-name>-key.service` should be used to define a dependency of a key in a service. The full issue behind the `keys.target` dependency is described at [NixOS/nixpkgs\#67265](https://github.com/NixOS/nixpkgs/issues/67265). + + The following services are affected by this: + + - [`services.dovecot2`](options.html#opt-services.dovecot2.enable) + + - [`services.nsd`](options.html#opt-services.nsd.enable) + + - [`services.softether`](options.html#opt-services.softether.enable) + + - [`services.strongswan`](options.html#opt-services.strongswan.enable) + + - [`services.strongswan-swanctl`](options.html#opt-services.strongswan-swanctl.enable) + + - [`services.httpd`](options.html#opt-services.httpd.enable) + +- The `security.acme.directory` option has been replaced by a read-only `security.acme.certs.<cert>.directory` option for each certificate you define. This will be a subdirectory of `/var/lib/acme`. You can use this read-only option to figure out where the certificates are stored for a specific certificate. For example, the `services.nginx.virtualhosts.<name>.enableACME` option will use this directory option to find the certs for the virtual host. + + `security.acme.preDelay` and `security.acme.activationDelay` options have been removed. To execute a service before certificates are provisioned or renewed add a `RequiredBy=acme-${cert}.service` to any service. + + Furthermore, the acme module will not automatically add a dependency on `lighttpd.service` anymore. If you are using certficates provided by letsencrypt for lighttpd, then you should depend on the certificate service `acme-${cert}.service>` manually. + + For nginx, the dependencies are still automatically managed when `services.nginx.virtualhosts.<name>.enableACME` is enabled just like before. What changed is that nginx now directly depends on the specific certificates that it needs, instead of depending on the catch-all `acme-certificates.target`. This target unit was also removed from the codebase. This will mean nginx will no longer depend on certificates it isn\'t explicitly managing and fixes a bug with certificate renewal ordering racing with nginx restarting which could lead to nginx getting in a broken state as described at [NixOS/nixpkgs\#60180](https://github.com/NixOS/nixpkgs/issues/60180). + +- The old deprecated `emacs` package sets have been dropped. What used to be called `emacsPackagesNg` is now simply called `emacsPackages`. + +- `services.xserver.desktopManager.xterm` is now disabled by default if `stateVersion` is 19.09 or higher. Previously the xterm desktopManager was enabled when xserver was enabled, but it isn\'t useful for all people so it didn\'t make sense to have any desktopManager enabled default. + +- The WeeChat plugin `pkgs.weechatScripts.weechat-xmpp` has been removed as it doesn\'t receive any updates from upstream and depends on outdated Python2-based modules. + +- Old unsupported versions (`logstash5`, `kibana5`, `filebeat5`, `heartbeat5`, `metricbeat5`, `packetbeat5`) of the ELK-stack and Elastic beats have been removed. + +- For NixOS 19.03, both Prometheus 1 and 2 were available to allow for a seamless transition from version 1 to 2 with existing setups. Because Prometheus 1 is no longer developed, it was removed. Prometheus 2 is now configured with `services.prometheus`. + +- Citrix Receiver (`citrix_receiver`) has been dropped in favor of Citrix Workspace (`citrix_workspace`). + +- The `services.gitlab` module has had its literal secret options (`services.gitlab.smtp.password`, `services.gitlab.databasePassword`, `services.gitlab.initialRootPassword`, `services.gitlab.secrets.secret`, `services.gitlab.secrets.db`, `services.gitlab.secrets.otp` and `services.gitlab.secrets.jws`) replaced by file-based versions (`services.gitlab.smtp.passwordFile`, `services.gitlab.databasePasswordFile`, `services.gitlab.initialRootPasswordFile`, `services.gitlab.secrets.secretFile`, `services.gitlab.secrets.dbFile`, `services.gitlab.secrets.otpFile` and `services.gitlab.secrets.jwsFile`). This was done so that secrets aren\'t stored in the world-readable nix store, but means that for each option you\'ll have to create a file with the same exact string, add \"File\" to the end of the option name, and change the definition to a string pointing to the corresponding file; e.g. `services.gitlab.databasePassword = "supersecurepassword"` becomes `services.gitlab.databasePasswordFile = "/path/to/secret_file"` where the file `secret_file` contains the string `supersecurepassword`. + + The state path (`services.gitlab.statePath`) now has the following restriction: no parent directory can be owned by any other user than `root` or the user specified in `services.gitlab.user`; i.e. if `services.gitlab.statePath` is set to `/var/lib/gitlab/state`, `gitlab` and all parent directories must be owned by either `root` or the user specified in `services.gitlab.user`. + +- The `networking.useDHCP` option is unsupported in combination with `networking.useNetworkd` in anticipation of defaulting to it. It has to be set to `false` and enabled per interface with `networking.interfaces.<name>.useDHCP = true;` + +- The Twitter client `corebird` has been dropped as [it is discontinued and does not work against the new Twitter API](https://www.patreon.com/posts/corebirds-future-18921328). Please use the fork `cawbird` instead which has been adapted to the API changes and is still maintained. + +- The `nodejs-11_x` package has been removed as it\'s EOLed by upstream. + +- Because of the systemd upgrade, systemd-timesyncd will no longer work if `system.stateVersion` is not set correctly. When upgrading from NixOS 19.03, please make sure that `system.stateVersion` is set to `"19.03"`, or lower if the installation dates back to an earlier version of NixOS. + +- Due to the short lifetime of non-LTS kernel releases package attributes like `linux_5_1`, `linux_5_2` and `linux_5_3` have been removed to discourage dependence on specific non-LTS kernel versions in stable NixOS releases. Going forward, versioned attributes like `linux_4_9` will exist for LTS versions only. Please use `linux_latest` or `linux_testing` if you depend on non-LTS releases. Keep in mind that `linux_latest` and `linux_testing` will change versions under the hood during the lifetime of a stable release and might include breaking changes. + +- Because of the systemd upgrade, some network interfaces might change their name. For details see [ upstream docs](https://www.freedesktop.org/software/systemd/man/systemd.net-naming-scheme.html#History) or [ our ticket](https://github.com/NixOS/nixpkgs/issues/71086). + +## Other Notable Changes {#sec-release-19.09-notable-changes} + +- The `documentation` module gained an option named `documentation.nixos.includeAllModules` which makes the generated configuration.nix 5 manual page include all options from all NixOS modules included in a given `configuration.nix` configuration file. Currently, it is set to `false` by default as enabling it frequently prevents evaluation. But the plan is to eventually have it set to `true` by default. Please set it to `true` now in your `configuration.nix` and fix all the bugs it uncovers. + +- The `vlc` package gained support for Chromecast streaming, enabled by default. TCP port 8010 must be open for it to work, so something like `networking.firewall.allowedTCPPorts = [ 8010 ];` may be required in your configuration. Also consider enabling [ Accelerated Video Playback](https://nixos.wiki/wiki/Accelerated_Video_Playback) for better transcoding performance. + +- The following changes apply if the `stateVersion` is changed to 19.09 or higher. For `stateVersion = "19.03"` or lower the old behavior is preserved. + + - `solr.package` defaults to `pkgs.solr_8`. + +- The `hunspellDicts.fr-any` dictionary now ships with `fr_FR.{aff,dic}` which is linked to `fr-toutesvariantes.{aff,dic}`. + +- The `mysql` service now runs as `mysql` user. Previously, systemd did execute it as root, and mysql dropped privileges itself. This includes `ExecStartPre=` and `ExecStartPost=` phases. To accomplish that, runtime and data directory setup was delegated to RuntimeDirectory and tmpfiles. + +- With the upgrade to systemd version 242 the `systemd-timesyncd` service is no longer using `DynamicUser=yes`. In order for the upgrade to work we rely on an activation script to move the state from the old to the new directory. The older directory (prior `19.09`) was `/var/lib/private/systemd/timesync`. + + As long as the `system.config.stateVersion` is below `19.09` the state folder will migrated to its proper location (`/var/lib/systemd/timesync`), if required. + +- The package `avahi` is now built to look up service definitions from `/etc/avahi/services` instead of its output directory in the nix store. Accordingly the module `avahi` now supports custom service definitions via `services.avahi.extraServiceFiles`, which are then placed in the aforementioned directory. See avahi.service5 for more information on custom service definitions. + +- Since version 0.1.19, `cargo-vendor` honors package includes that are specified in the `Cargo.toml` file of Rust crates. `rustPlatform.buildRustPackage` uses `cargo-vendor` to collect and build dependent crates. Since this change in `cargo-vendor` changes the set of vendored files for most Rust packages, the hash that use used to verify the dependencies, `cargoSha256`, also changes. + + The `cargoSha256` hashes of all in-tree derivations that use `buildRustPackage` have been updated to reflect this change. However, third-party derivations that use `buildRustPackage` may have to be updated as well. + +- The `consul` package was upgraded past version `1.5`, so its deprecated legacy UI is no longer available. + +- The default resample-method for PulseAudio has been changed from the upstream default `speex-float-1` to `speex-float-5`. Be aware that low-powered ARM-based and MIPS-based boards will struggle with this so you\'ll need to set `hardware.pulseaudio.daemon.config.resample-method` back to `speex-float-1`. + +- The `phabricator` package and associated `httpd.extraSubservice`, as well as the `phd` service have been removed from nixpkgs due to lack of maintainer. + +- The `mercurial` `httpd.extraSubservice` has been removed from nixpkgs due to lack of maintainer. + +- The `trac` `httpd.extraSubservice` has been removed from nixpkgs because it was unmaintained. + +- The `foswiki` package and associated `httpd.extraSubservice` have been removed from nixpkgs due to lack of maintainer. + +- The `tomcat-connector` `httpd.extraSubservice` has been removed from nixpkgs. + +- It\'s now possible to change configuration in [services.nextcloud](options.html#opt-services.nextcloud.enable) after the initial deploy since all config parameters are persisted in an additional config file generated by the module. Previously core configuration like database parameters were set using their imperative installer after creating `/var/lib/nextcloud`. + +- There exists now `lib.forEach`, which is like `map`, but with arguments flipped. When mapping function body spans many lines (or has nested `map`s), it is often hard to follow which list is modified. + + Previous solution to this problem was either to use `lib.flip map` idiom or extract that anonymous mapping function to a named one. Both can still be used but `lib.forEach` is preferred over `lib.flip map`. + + The `/etc/sysctl.d/nixos.conf` file containing all the options set via [boot.kernel.sysctl](options.html#opt-boot.kernel.sysctl) was moved to `/etc/sysctl.d/60-nixos.conf`, as sysctl.d5 recommends prefixing all filenames in `/etc/sysctl.d` with a two-digit number and a dash to simplify the ordering of the files. + +- We now install the sysctl snippets shipped with systemd. + + - Loose reverse path filtering + + - Source route filtering + + - `fq_codel` as a packet scheduler (this helps to fight bufferbloat) + + This also configures the kernel to pass core dumps to `systemd-coredump`, and restricts the SysRq key combinations to the sync command only. These sysctl snippets can be found in `/etc/sysctl.d/50-*.conf`, and overridden via [boot.kernel.sysctl](options.html#opt-boot.kernel.sysctl) (which will place the parameters in `/etc/sysctl.d/60-nixos.conf`). + +- Core dumps are now processed by `systemd-coredump` by default. `systemd-coredump` behaviour can still be modified via `systemd.coredump.extraConfig`. To stick to the old behaviour (having the kernel dump to a file called `core` in the working directory), without piping it through `systemd-coredump`, set `systemd.coredump.enable` to `false`. + +- `systemd.packages` option now also supports generators and shutdown scripts. Old `systemd.generator-packages` option has been removed. + +- The `rmilter` package was removed with associated module and options due deprecation by upstream developer. Use `rspamd` in proxy mode instead. + +- systemd cgroup accounting via the [systemd.enableCgroupAccounting](options.html#opt-systemd.enableCgroupAccounting) option is now enabled by default. It now also enables the more recent Block IO and IP accounting features. + +- We no longer enable custom font rendering settings with `fonts.fontconfig.penultimate.enable` by default. The defaults from fontconfig are sufficient. + +- The `crashplan` package and the `crashplan` service have been removed from nixpkgs due to crashplan shutting down the service, while the `crashplansb` package and `crashplan-small-business` service have been removed from nixpkgs due to lack of maintainer. + + The [redis module](options.html#opt-services.redis.enable) was hardcoded to use the `redis` user, `/run/redis` as runtime directory and `/var/lib/redis` as state directory. Note that the NixOS module for Redis now disables kernel support for Transparent Huge Pages (THP), because this features causes major performance problems for Redis, e.g. (https://redis.io/topics/latency). + +- Using `fonts.enableDefaultFonts` adds a default emoji font `noto-fonts-emoji`. + + - `services.xserver.enable` + + - `programs.sway.enable` + + - `programs.way-cooler.enable` + + - `services.xrdp.enable` + +- The `altcoins` categorization of packages has been removed. You now access these packages at the top level, ie. `nix-shell -p dogecoin` instead of `nix-shell -p altcoins.dogecoin`, etc. + +- Ceph has been upgraded to v14.2.1. See the [release notes](https://ceph.com/releases/v14-2-0-nautilus-released/) for details. The mgr dashboard as well as osds backed by loop-devices is no longer explicitly supported by the package and module. Note: There\'s been some issues with python-cherrypy, which is used by the dashboard and prometheus mgr modules (and possibly others), hence 0000-dont-check-cherrypy-version.patch. + +- `pkgs.weechat` is now compiled against `pkgs.python3`. Weechat also recommends [to use Python3 in their docs.](https://weechat.org/scripts/python3/) diff --git a/nixos/doc/manual/release-notes/rl-2003.section.md b/nixos/doc/manual/release-notes/rl-2003.section.md new file mode 100644 index 00000000000..b92c7f6634c --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-2003.section.md @@ -0,0 +1,507 @@ +# Release 20.03 ("Markhor", 2020.04/20) {#sec-release-20.03} + +## Highlights {#sec-release-20.03-highlights} + +In addition to numerous new and upgraded packages, this release has the following highlights: + +- Support is planned until the end of October 2020, handing over to 20.09. + +- Core version changes: + + gcc: 8.3.0 -\> 9.2.0 + + glibc: 2.27 -\> 2.30 + + linux: 4.19 -\> 5.4 + + mesa: 19.1.5 -\> 19.3.3 + + openssl: 1.0.2u -\> 1.1.1d + +- Desktop version changes: + + plasma5: 5.16.5 -\> 5.17.5 + + kdeApplications: 19.08.2 -\> 19.12.3 + + gnome3: 3.32 -\> 3.34 + + pantheon: 5.0 -\> 5.1.3 + +- Linux kernel is updated to branch 5.4 by default (from 4.19). + +- Grub is updated to 2.04, adding support for booting from F2FS filesystems and Btrfs volumes using zstd compression. Note that some users have been unable to boot after upgrading to 2.04 - for more information, please see [this discussion](https://github.com/NixOS/nixpkgs/issues/61718#issuecomment-617618503). + +- Postgresql for NixOS service now defaults to v11. + +- The graphical installer image starts the graphical session automatically. Before you\'d be greeted by a tty and asked to enter `systemctl start display-manager`. It is now possible to disable the display-manager from running by selecting the `Disable display-manager` quirk in the boot menu. + +- GNOME 3 has been upgraded to 3.34. Please take a look at their [Release Notes](https://help.gnome.org/misc/release-notes/3.34) for details. + +- If you enable the Pantheon Desktop Manager via [services.xserver.desktopManager.pantheon.enable](options.html#opt-services.xserver.desktopManager.pantheon.enable), we now default to also use [ Pantheon\'s newly designed greeter ](https://blog.elementary.io/say-hello-to-the-new-greeter/). Contrary to NixOS\'s usual update policy, Pantheon will receive updates during the cycle of NixOS 20.03 when backwards compatible. + +- By default zfs pools will now be trimmed on a weekly basis. Trimming is only done on supported devices (i.e. NVME or SSDs) and should improve throughput and lifetime of these devices. It is controlled by the `services.zfs.trim.enable` varname. The zfs scrub service (`services.zfs.autoScrub.enable`) and the zfs autosnapshot service (`services.zfs.autoSnapshot.enable`) are now only enabled if zfs is set in `config.boot.initrd.supportedFilesystems` or `config.boot.supportedFilesystems`. These lists will automatically contain zfs as soon as any zfs mountpoint is configured in `fileSystems`. + +- `nixos-option` has been rewritten in C++, speeding it up, improving correctness, and adding a `-r` option which prints all options and their values recursively. + +- `services.xserver.desktopManager.default` and `services.xserver.windowManager.default` options were replaced by a single [services.xserver.displayManager.defaultSession](options.html#opt-services.xserver.displayManager.defaultSession) option to improve support for upstream session files. If you used something like: + + ```nix + { + services.xserver.desktopManager.default = "xfce"; + services.xserver.windowManager.default = "icewm"; + } + ``` + + you should change it to: + + ```nix + { + services.xserver.displayManager.defaultSession = "xfce+icewm"; + } + ``` + +- The testing driver implementation in NixOS is now in Python `make-test-python.nix`. This was done by Jacek Galowicz ([\@tfc](https://github.com/tfc)), and with the collaboration of Julian Stecklina ([\@blitz](https://github.com/blitz)) and Jana Traue ([\@jtraue](https://github.com/jtraue)). All documentation has been updated to use this testing driver, and a vast majority of the 286 tests in NixOS were ported to python driver. In 20.09 the Perl driver implementation, `make-test.nix`, is slated for removal. This should give users of the NixOS integration framework a transitory period to rewrite their tests to use the Python implementation. Users of the Perl driver will see this warning everytime they use it: + + ```ShellSession + $ warning: Perl VM tests are deprecated and will be removed for 20.09. + Please update your tests to use the python test driver. + See https://github.com/NixOS/nixpkgs/pull/71684 for details. + ``` + + API compatibility is planned to be kept for at least the next release with the perl driver. + +## New Services {#sec-release-20.03-new-services} + +The following new services were added since the last release: + +- The kubernetes kube-proxy now supports a new hostname configuration `services.kubernetes.proxy.hostname` which has to be set if the hostname of the node should be non default. + +- UPower\'s configuration is now managed by NixOS and can be customized via `services.upower`. + +- To use Geary you should enable [programs.geary.enable](options.html#opt-programs.geary.enable) instead of just adding it to [environment.systemPackages](options.html#opt-environment.systemPackages). It was created so Geary could function properly outside of GNOME. + +- `./config/console.nix` + +- `./hardware/brillo.nix` + +- `./hardware/tuxedo-keyboard.nix` + +- `./programs/bandwhich.nix` + +- `./programs/bash-my-aws.nix` + +- `./programs/liboping.nix` + +- `./programs/traceroute.nix` + +- `./services/backup/sanoid.nix` + +- `./services/backup/syncoid.nix` + +- `./services/backup/zfs-replication.nix` + +- `./services/continuous-integration/buildkite-agents.nix` + +- `./services/databases/victoriametrics.nix` + +- `./services/desktops/gnome3/gnome-initial-setup.nix` + +- `./services/desktops/neard.nix` + +- `./services/games/openarena.nix` + +- `./services/hardware/fancontrol.nix` + +- `./services/mail/sympa.nix` + +- `./services/misc/freeswitch.nix` + +- `./services/misc/mame.nix` + +- `./services/monitoring/do-agent.nix` + +- `./services/monitoring/prometheus/xmpp-alerts.nix` + +- `./services/network-filesystems/orangefs/server.nix` + +- `./services/network-filesystems/orangefs/client.nix` + +- `./services/networking/3proxy.nix` + +- `./services/networking/corerad.nix` + +- `./services/networking/go-shadowsocks2.nix` + +- `./services/networking/ntp/openntpd.nix` + +- `./services/networking/shorewall.nix` + +- `./services/networking/shorewall6.nix` + +- `./services/networking/spacecookie.nix` + +- `./services/networking/trickster.nix` + +- `./services/networking/v2ray.nix` + +- `./services/networking/xandikos.nix` + +- `./services/networking/yggdrasil.nix` + +- `./services/web-apps/dokuwiki.nix` + +- `./services/web-apps/gotify-server.nix` + +- `./services/web-apps/grocy.nix` + +- `./services/web-apps/ihatemoney` + +- `./services/web-apps/moinmoin.nix` + +- `./services/web-apps/trac.nix` + +- `./services/web-apps/trilium.nix` + +- `./services/web-apps/shiori.nix` + +- `./services/web-servers/ttyd.nix` + +- `./services/x11/picom.nix` + +- `./services/x11/hardware/digimend.nix` + +- `./services/x11/imwheel.nix` + +- `./virtualisation/cri-o.nix` + +## Backward Incompatibilities {#sec-release-20.03-incompatibilities} + +When upgrading from a previous release, please be aware of the following incompatible changes: + +- The dhcpcd package [ does not request IPv4 addresses for tap and bridge interfaces anymore by default](https://roy.marples.name/archives/dhcpcd-discuss/0002621.html). In order to still get an address on a bridge interface, one has to disable `networking.useDHCP` and explicitly enable `networking.interfaces.<name>.useDHCP` on every interface, that should get an address via DHCP. This way, dhcpcd is configured in an explicit way about which interface to run on. + +- GnuPG is now built without support for a graphical passphrase entry by default. Please enable the `gpg-agent` user service via the NixOS option `programs.gnupg.agent.enable`. Note that upstream recommends using `gpg-agent` and will spawn a `gpg-agent` on the first invocation of GnuPG anyway. + +- The `dynamicHosts` option has been removed from the [NetworkManager](options.html#opt-networking.networkmanager.enable) module. Allowing (multiple) regular users to override host entries affecting the whole system opens up a huge attack vector. There seem to be very rare cases where this might be useful. Consider setting system-wide host entries using [networking.hosts](options.html#opt-networking.hosts), provide them via the DNS server in your network, or use [environment.etc](options.html#opt-environment.etc) to add a file into `/etc/NetworkManager/dnsmasq.d` reconfiguring `hostsdir`. + +- The `99-main.network` file was removed. Matching all network interfaces caused many breakages, see [\#18962](https://github.com/NixOS/nixpkgs/pull/18962) and [\#71106](https://github.com/NixOS/nixpkgs/pull/71106). + + We already don\'t support the global [networking.useDHCP](options.html#opt-networking.useDHCP), [networking.defaultGateway](options.html#opt-networking.defaultGateway) and [networking.defaultGateway6](options.html#opt-networking.defaultGateway6) options if [networking.useNetworkd](options.html#opt-networking.useNetworkd) is enabled, but direct users to configure the per-device [networking.interfaces.\<name\>....](options.html#opt-networking.interfaces) options. + +- The stdenv now runs all bash with `set -u`, to catch the use of undefined variables. Before, it itself used `set -u` but was careful to unset it so other packages\' code ran as before. Now, all bash code is held to the same high standard, and the rather complex stateful manipulation of the options can be discarded. + +- The SLIM Display Manager has been removed, as it has been unmaintained since 2013. Consider migrating to a different display manager such as LightDM (current default in NixOS), SDDM, GDM, or using the startx module which uses Xinitrc. + +- The Way Cooler wayland compositor has been removed, as the project has been officially canceled. There are no more `way-cooler` attribute and `programs.way-cooler` options. + +- The BEAM package set has been deleted. You will only find there the different interpreters. You should now use the different build tools coming with the languages with sandbox mode disabled. + +- There is now only one Xfce package-set and module. This means that attributes `xfce4-14` and `xfceUnstable` all now point to the latest Xfce 4.14 packages. And in the future NixOS releases will be the latest released version of Xfce available at the time of the release\'s development (if viable). + +- The [phpfpm](options.html#opt-services.phpfpm.pools) module now sets `PrivateTmp=true` in its systemd units for better process isolation. If you rely on `/tmp` being shared with other services, explicitly override this by setting `serviceConfig.PrivateTmp` to `false` for each phpfpm unit. + +- KDE's old multimedia framework Phonon no longer supports Qt 4. For that reason, Plasma desktop also does not have `enableQt4Support` option any more. + +- The BeeGFS module has been removed. + +- The osquery module has been removed. + +- Going forward, `~/bin` in the users home directory will no longer be in `PATH` by default. If you depend on this you should set the option `environment.homeBinInPath` to `true`. The aforementioned option was added this release. + +- The `buildRustCrate` infrastructure now produces `lib` outputs in addition to the `out` output. This has led to drastically reduced closure sizes for some rust crates since development dependencies are now in the `lib` output. + +- Pango was upgraded to 1.44, which no longer uses freetype for font loading. This means that type1 and bitmap fonts are no longer supported in applications relying on Pango for font rendering (notably, GTK application). See [ upstream issue](https://gitlab.gnome.org/GNOME/pango/issues/386) for more information. + +- The `roundcube` module has been hardened. + + - The password of the database is not written world readable in the store any more. If `database.host` is set to `localhost`, then a unix user of the same name as the database will be created and PostreSQL peer authentication will be used, removing the need for a password. Otherwise, a password is still needed and can be provided with the new option `database.passwordFile`, which should be set to the path of a file containing the password and readable by the user `nginx` only. The `database.password` option is insecure and deprecated. Usage of this option will print a warning. + + - A random `des_key` is set by default in the configuration of roundcube, instead of using the hardcoded and insecure default. To ensure a clean migration, all users will be logged out when you upgrade to this release. + +- The packages `openobex` and `obexftp` are no longer installed when enabling Bluetooth via `hardware.bluetooth.enable`. + +- The `dump1090` derivation has been changed to use FlightAware\'s dump1090 as its upstream. However, this version does not have an internal webserver anymore. The assets in the `share/dump1090` directory of the derivation can be used in conjunction with an external webserver to replace this functionality. + +- The fourStore and fourStoreEndpoint modules have been removed. + +- Polkit no longer has the user of uid 0 (root) as an admin identity. We now follow the upstream default of only having every member of the wheel group admin privileged. Before it was root and members of wheel. The positive outcome of this is pkexec GUI popups or terminal prompts will no longer require the user to choose between two essentially equivalent choices (whether to perform the action as themselves with wheel permissions, or as the root user). + +- NixOS containers no longer build NixOS manual by default. This saves evaluation time, especially if there are many declarative containers defined. Note that this is already done when `<nixos/modules/profiles/minimal.nix>` module is included in container config. + +- The `kresd` services deprecates the `interfaces` option in favor of the `listenPlain` option which requires full [systemd.socket compatible](https://www.freedesktop.org/software/systemd/man/systemd.socket.html#ListenStream=) declaration which always include a port. + +- Virtual console options have been reorganized and can be found under a single top-level attribute: `console`. The full set of changes is as follows: + + - `i18n.consoleFont` renamed to [console.font](options.html#opt-console.font) + + - `i18n.consoleKeyMap` renamed to [console.keyMap](options.html#opt-console.keyMap) + + - `i18n.consoleColors` renamed to [console.colors](options.html#opt-console.colors) + + - `i18n.consolePackages` renamed to [console.packages](options.html#opt-console.packages) + + - `i18n.consoleUseXkbConfig` renamed to [console.useXkbConfig](options.html#opt-console.useXkbConfig) + + - `boot.earlyVconsoleSetup` renamed to [console.earlySetup](options.html#opt-console.earlySetup) + + - `boot.extraTTYs` renamed to `console.extraTTYs`. + +- The [awstats](options.html#opt-services.awstats.enable) module has been rewritten to serve stats via static html pages, updated on a timer, over [nginx](options.html#opt-services.nginx.virtualHosts), instead of dynamic cgi pages over [apache](options.html#opt-services.httpd.enable). + + Minor changes will be required to migrate existing configurations. Details of the required changes can seen by looking through the [awstats](options.html#opt-services.awstats.enable) module. + +- The httpd module no longer provides options to support serving web content without defining a virtual host. As a result of this the [services.httpd.logPerVirtualHost](options.html#opt-services.httpd.logPerVirtualHost) option now defaults to `true` instead of `false`. Please update your configuration to make use of [services.httpd.virtualHosts](options.html#opt-services.httpd.virtualHosts). + + The [services.httpd.virtualHosts.\<name\>](options.html#opt-services.httpd.virtualHosts) option has changed type from a list of submodules to an attribute set of submodules, better matching [services.nginx.virtualHosts.\<name\>](options.html#opt-services.nginx.virtualHosts). + + This change comes with the addition of the following options which mimic the functionality of their `nginx` counterparts: [services.httpd.virtualHosts.\<name\>.addSSL](options.html#opt-services.httpd.virtualHosts), [services.httpd.virtualHosts.\<name\>.forceSSL](options.html#opt-services.httpd.virtualHosts), [services.httpd.virtualHosts.\<name\>.onlySSL](options.html#opt-services.httpd.virtualHosts), [services.httpd.virtualHosts.\<name\>.enableACME](options.html#opt-services.httpd.virtualHosts), [services.httpd.virtualHosts.\<name\>.acmeRoot](options.html#opt-services.httpd.virtualHosts), and [services.httpd.virtualHosts.\<name\>.useACMEHost](options.html#opt-services.httpd.virtualHosts). + +- For NixOS configuration options, the `loaOf` type has been deprecated and will be removed in a future release. In nixpkgs, options of this type will be changed to `attrsOf` instead. If you were using one of these in your configuration, you will see a warning suggesting what changes will be required. + + For example, [users.users](options.html#opt-users.users) is a `loaOf` option that is commonly used as follows: + + ```nix + { + users.users = + [ { name = "me"; + description = "My personal user."; + isNormalUser = true; + } + ]; + } + ``` + + This should be rewritten by removing the list and using the value of `name` as the name of the attribute set: + + ```nix + { + users.users.me = + { description = "My personal user."; + isNormalUser = true; + }; + } + ``` + + For more information on this change have look at these links: [issue \#1800](https://github.com/NixOS/nixpkgs/issues/1800), [PR \#63103](https://github.com/NixOS/nixpkgs/pull/63103). + +- For NixOS modules, the types `types.submodule` and `types.submoduleWith` now support paths as allowed values, similar to how `imports` supports paths. Because of this, if you have a module that defines an option of type `either (submodule ...) path`, it will break since a path is now treated as the first type instead of the second. To fix this, change the type to `either path (submodule ...)`. + +- The [Buildkite Agent](options.html#opt-services.buildkite-agents) module and corresponding packages have been updated to 3.x, and to support multiple instances of the agent running at the same time. This means you will have to rename `services.buildkite-agent` to `services.buildkite-agents.<name>`. Furthermore, the following options have been changed: + + - `services.buildkite-agent.meta-data` has been renamed to [services.buildkite-agents.\<name\>.tags](options.html#opt-services.buildkite-agents), to match upstreams naming for 3.x. Its type has also changed - it now accepts an attrset of strings. + + - The`services.buildkite-agent.openssh.publicKeyPath` option has been removed, as it\'s not necessary to deploy public keys to clone private repositories. + + - `services.buildkite-agent.openssh.privateKeyPath` has been renamed to [buildkite-agents.\<name\>.privateSshKeyPath](options.html#opt-services.buildkite-agents), as the whole `openssh` now only contained that single option. + + - [services.buildkite-agents.\<name\>.shell](options.html#opt-services.buildkite-agents) has been introduced, allowing to specify a custom shell to be used. + +- The `citrix_workspace_19_3_0` package has been removed as it will be EOLed within the lifespan of 20.03. For further information, please refer to the [support and maintenance information](https://www.citrix.com/de-de/support/product-lifecycle/milestones/receiver.html) from upstream. + +- The `gcc5` and `gfortran5` packages have been removed. + +- The `services.xserver.displayManager.auto` module has been removed. It was only intended for use in internal NixOS tests, and gave the false impression of it being a special display manager when it\'s actually LightDM. Please use the `services.xserver.displayManager.lightdm.autoLogin` options instead, or any other display manager in NixOS as they all support auto-login. If you used this module specifically because it permitted root auto-login you can override the lightdm-autologin pam module like: + + ```nix + { + security.pam.services.lightdm-autologin.text = lib.mkForce '' + auth requisite pam_nologin.so + auth required pam_succeed_if.so quiet + auth required pam_permit.so + + account include lightdm + + password include lightdm + + session include lightdm + ''; + } + ``` + + The difference is the: + + ``` + auth required pam_succeed_if.so quiet + ``` + + line, where default it\'s: + + ``` + auth required pam_succeed_if.so uid >= 1000 quiet + ``` + + not permitting users with uid\'s below 1000 (like root). All other display managers in NixOS are configured like this. + +- There have been lots of improvements to the Mailman module. As a result, + + - The `services.mailman.hyperkittyBaseUrl` option has been renamed to [services.mailman.hyperkitty.baseUrl](options.html#opt-services.mailman.hyperkitty.baseUrl). + + - The `services.mailman.hyperkittyApiKey` option has been removed. This is because having an option for the Hyperkitty API key meant that the API key would be stored in the world-readable Nix store, which was a security vulnerability. A new Hyperkitty API key will be generated the first time the new Hyperkitty service is run, and it will then be persisted outside of the Nix store. To continue using Hyperkitty, you must set [services.mailman.hyperkitty.enable](options.html#opt-services.mailman.hyperkitty.enable) to `true`. + + - Additionally, some Postfix configuration must now be set manually instead of automatically by the Mailman module: + + ```nix + { + services.postfix.relayDomains = [ "hash:/var/lib/mailman/data/postfix_domains" ]; + services.postfix.config.transport_maps = [ "hash:/var/lib/mailman/data/postfix_lmtp" ]; + services.postfix.config.local_recipient_maps = [ "hash:/var/lib/mailman/data/postfix_lmtp" ]; + } + ``` + + This is because some users may want to include other values in these lists as well, and this was not possible if they were set automatically by the Mailman module. It would not have been possible to just concatenate values from multiple modules each setting the values they needed, because the order of elements in the list is significant. + +- The LLVM versions 3.5, 3.9 and 4 (including the corresponding CLang versions) have been dropped. + +- The `networking.interfaces.*.preferTempAddress` option has been replaced by `networking.interfaces.*.tempAddress`. The new option allows better control of the IPv6 temporary addresses, including completely disabling them for interfaces where they are not needed. + +- Rspamd was updated to version 2.2. Read [ the upstream migration notes](https://rspamd.com/doc/migration.html#migration-to-rspamd-20) carefully. Please be especially aware that some modules were removed and the default Bayes backend is now Redis. + +- The `*psu` versions of oraclejdk8 have been removed as they aren\'t provided by upstream anymore. + +- The `services.dnscrypt-proxy` module has been removed as it used the deprecated version of dnscrypt-proxy. We\'ve added [services.dnscrypt-proxy2.enable](options.html#opt-services.dnscrypt-proxy2.enable) to use the supported version. This module supports configuration via the Nix attribute set [services.dnscrypt-proxy2.settings](options.html#opt-services.dnscrypt-proxy2.settings), or by passing a TOML configuration file via [services.dnscrypt-proxy2.configFile](options.html#opt-services.dnscrypt-proxy2.configFile). + + ```nix + { + # Example configuration: + services.dnscrypt-proxy2.enable = true; + services.dnscrypt-proxy2.settings = { + listen_addresses = [ "127.0.0.1:43" ]; + sources.public-resolvers = { + urls = [ "https://download.dnscrypt.info/resolvers-list/v2/public-resolvers.md" ]; + cache_file = "public-resolvers.md"; + minisign_key = "RWQf6LRCGA9i53mlYecO4IzT51TGPpvWucNSCh1CBM0QTaLn73Y7GFO3"; + refresh_delay = 72; + }; + }; + + services.dnsmasq.enable = true; + services.dnsmasq.servers = [ "127.0.0.1#43" ]; + } + ``` + +- `qesteidutil` has been deprecated in favor of `qdigidoc`. + +- sqldeveloper_18 has been removed as it\'s not maintained anymore, sqldeveloper has been updated to version `19.4`. Please note that this means that this means that the oraclejdk is now required. For further information please read the [release notes](https://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/sqldev-relnotes-194-5908846.html). + +- Haskell `env` and `shellFor` dev shell environments now organize dependencies the same way as regular builds. In particular, rather than receiving all the different lists of dependencies mashed together as one big list, and then partitioning into Haskell and non-Hakell dependencies, they work from the original many different dependency parameters and don\'t need to algorithmically partition anything. + + This means that if you incorrectly categorize a dependency, e.g. non-Haskell library dependency as a `buildDepends` or run-time Haskell dependency as a `setupDepends`, whereas things would have worked before they may not work now. + +- The gcc-snapshot-package has been removed. It\'s marked as broken for \>2 years and used to point to a fairly old snapshot from the gcc7-branch. + +- The nixos-build-vms8 -script now uses the python test-driver. + +- The riot-web package now accepts configuration overrides as an attribute set instead of a string. A formerly used JSON configuration can be converted to an attribute set with `builtins.fromJSON`. + + The new default configuration also disables automatic guest account registration and analytics to improve privacy. The previous behavior can be restored by setting `config.riot-web.conf = { disable_guests = false; piwik = true; }`. + +- Stand-alone usage of `Upower` now requires `services.upower.enable` instead of just installing into [environment.systemPackages](options.html#opt-environment.systemPackages). + +- nextcloud has been updated to `v18.0.2`. This means that users from NixOS 19.09 can\'t upgrade directly since you can only move one version forward and 19.09 uses `v16.0.8`. + + To provide a safe upgrade-path and to circumvent similar issues in the future, the following measures were taken: + + - The pkgs.nextcloud-attribute has been removed and replaced with versioned attributes (currently pkgs.nextcloud17 and pkgs.nextcloud18). With this change major-releases can be backported without breaking stuff and to make upgrade-paths easier. + + - Existing setups will be detected using [system.stateVersion](options.html#opt-system.stateVersion): by default, nextcloud17 will be used, but will raise a warning which notes that after that deploy it\'s recommended to update to the latest stable version (nextcloud18) by declaring the newly introduced setting [services.nextcloud.package](options.html#opt-services.nextcloud.package). + + - Users with an overlay (e.g. to use nextcloud at version `v18` on `19.09`) will get an evaluation error by default. This is done to ensure that our [package](options.html#opt-services.nextcloud.package)-option doesn\'t select an older version by accident. It\'s recommended to use pkgs.nextcloud18 or to set [package](options.html#opt-services.nextcloud.package) to pkgs.nextcloud explicitly. + + ::: {.warning} + Please note that if you\'re coming from `19.03` or older, you have to manually upgrade to `19.09` first to upgrade your server to Nextcloud v16. + ::: + +- Hydra has gained a massive performance improvement due to [some database schema changes](https://github.com/NixOS/hydra/pull/710) by adding several IDs and better indexing. However, it\'s necessary to upgrade Hydra in multiple steps: + + - At first, an older version of Hydra needs to be deployed which adds those (nullable) columns. When having set [stateVersion ](options.html#opt-system.stateVersion) to a value older than `20.03`, this package will be selected by default from the module when upgrading. Otherwise, the package can be deployed using the following config: + + ```nix + { pkgs, ... }: { + services.hydra.package = pkgs.hydra-migration; + } + ``` + +- Automatically fill the newly added ID columns on the server by running the following command: + + ```ShellSession + $ hydra-backfill-ids + ``` + ::: {.warning} + Please note that this process can take a while depending on your database-size! + ::: + +- Deploy a newer version of Hydra to activate the DB optimizations. This can be done by using hydra-unstable. This package already includes [flake-support](https://github.com/nixos/rfcs/pull/49) and is therefore compiled against pkgs.nixFlakes. + + ::: {.warning} + If your [stateVersion](options.html#opt-system.stateVersion) is set to `20.03` or greater, hydra-unstable will be used automatically! This will break your setup if you didn\'t run the migration. + ::: + + Please note that Hydra is currently not available with nixStable as this doesn\'t compile anymore. + + ::: {.warning} + pkgs.hydra has been removed to ensure a graceful database-migration using the dedicated package-attributes. If you still have pkgs.hydra defined in e.g. an overlay, an assertion error will be thrown. To circumvent this, you need to set [services.hydra.package](options.html#opt-services.hydra.package) to pkgs.hydra explicitly and make sure you know what you\'re doing! + ::: + +- The TokuDB storage engine will be disabled in mariadb 10.5. It is recommended to switch to RocksDB. See also [TokuDB](https://mariadb.com/kb/en/tokudb/). + +## Other Notable Changes {#sec-release-20.03-notable-changes} + +- SD images are now compressed by default using `bzip2`. + +- The nginx web server previously started its master process as root privileged, then ran worker processes as a less privileged identity user (the `nginx` user). This was changed to start all of nginx as a less privileged user (defined by `services.nginx.user` and `services.nginx.group`). As a consequence, all files that are needed for nginx to run (included configuration fragments, SSL certificates and keys, etc.) must now be readable by this less privileged user/group. + + To continue to use the old approach, you can configure: + + ```nix + { + services.nginx.appendConfig = let cfg = config.services.nginx; in ''user ${cfg.user} ${cfg.group};''; + systemd.services.nginx.serviceConfig.User = lib.mkForce "root"; + } + ``` + +- OpenSSH has been upgraded from 7.9 to 8.1, improving security and adding features but with potential incompatibilities. Consult the [ release announcement](https://www.openssh.com/txt/release-8.1) for more information. + +- `PRETTY_NAME` in `/etc/os-release` now uses the short rather than full version string. + +- The ACME module has switched from simp-le to [lego](https://github.com/go-acme/lego) which allows us to support DNS-01 challenges and wildcard certificates. The following options have been added: [security.acme.acceptTerms](options.html#opt-security.acme.acceptTerms), [security.acme.certs.\<name\>.dnsProvider](options.html#opt-security.acme.certs), [security.acme.certs.\<name\>.credentialsFile](options.html#opt-security.acme.certs), [security.acme.certs.\<name\>.dnsPropagationCheck](options.html#opt-security.acme.certs). As well as this, the options `security.acme.acceptTerms` and either `security.acme.email` or `security.acme.certs.<name>.email` must be set in order to use the ACME module. Certificates will be regenerated on activation, no account or certificate will be migrated from simp-le. In particular private keys will not be preserved. However, the credentials for simp-le are preserved and thus it is possible to roll back to previous versions without breaking certificate generation. Note also that in contrary to simp-le a new private key is recreated at each renewal by default, which can have consequences if you embed your public key in apps. + +- It is now possible to unlock LUKS-Encrypted file systems using a FIDO2 token via `boot.initrd.luks.fido2Support`. + +- Predictably named network interfaces get renamed in stage-1. This means that it is possible to use the proper interface name for e.g. Dropbear setups. + + For further reference, please read [\#68953](https://github.com/NixOS/nixpkgs/pull/68953) or the corresponding [discourse thread](https://discourse.nixos.org/t/predictable-network-interface-names-in-initrd/4055). + +- The matrix-synapse-package has been updated to [v1.11.1](https://github.com/matrix-org/synapse/releases/tag/v1.11.1). Due to [stricter requirements](https://github.com/matrix-org/synapse/releases/tag/v1.10.0rc1) for database configuration when using postgresql, the automated database setup of the module has been removed to avoid any further edge-cases. + + matrix-synapse expects `postgresql`-databases to have the options `LC_COLLATE` and `LC_CTYPE` set to [`'C'`](https://www.postgresql.org/docs/12/locale.html) which basically instructs `postgresql` to ignore any locale-based preferences. + + Depending on your setup, you need to incorporate one of the following changes in your setup to upgrade to 20.03: + + - If you use `sqlite3` you don\'t need to do anything. + + - If you use `postgresql` on a different server, you don\'t need to change anything as well since this module was never designed to configure remote databases. + + - If you use `postgresql` and configured your synapse initially on `19.09` or older, you simply need to enable postgresql-support explicitly: + + ```nix + { ... }: { + services.matrix-synapse = { + enable = true; + /* and all the other config you've defined here */ + }; + services.postgresql.enable = true; + } + ``` + +- If you deploy a fresh matrix-synapse, you need to configure the database yourself (e.g. by using the [services.postgresql.initialScript](options.html#opt-services.postgresql.initialScript) option). An example for this can be found in the [documentation of the Matrix module](#module-services-matrix). + +- If you initially deployed your matrix-synapse on `nixos-unstable` _after_ the `19.09`-release, your database is misconfigured due to a regression in NixOS. For now, matrix-synapse will startup with a warning, but it\'s recommended to reconfigure the database to set the values `LC_COLLATE` and `LC_CTYPE` to [`'C'`](https://www.postgresql.org/docs/12/locale.html). + +- The [systemd.network.links](options.html#opt-systemd.network.links) option is now respected even when [systemd-networkd](options.html#opt-systemd.network.enable) is disabled. This mirrors the behaviour of systemd - It\'s udev that parses `.link` files, not `systemd-networkd`. + +- mongodb has been updated to version `3.4.24`. + + ::: {.warning} + Please note that mongodb has been relicensed under their own [` sspl`](https://www.mongodb.com/licensing/server-side-public-license/faq)-license. Since it\'s not entirely free and not OSI-approved, it\'s listed as non-free. This means that Hydra doesn\'t provide prebuilt mongodb-packages and needs to be built locally. + ::: diff --git a/nixos/doc/manual/release-notes/rl-2009.section.md b/nixos/doc/manual/release-notes/rl-2009.section.md new file mode 100644 index 00000000000..79be2a56a54 --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-2009.section.md @@ -0,0 +1,747 @@ +# Release 20.09 ("Nightingale", 2020.10/27) {#sec-release-20.09} + +Support is planned until the end of June 2021, handing over to 21.05.

If you have `AuthorizedKeysCommand` in your [services.openssh.extraConfig](options.html#opt-services.openssh.extraConfig) you should make use of these new options instead. + + - There is a new module for Podman (`virtualisation.podman`), a drop-in replacement for the Docker command line. + + - The new `virtualisation.containers` module manages configuration shared by the CRI-O and Podman modules. + + - Declarative Docker containers are renamed from `docker-containers` to `virtualisation.oci-containers.containers`. This is to make it possible to use `podman` instead of `docker`. + + - The new option [documentation.man.generateCaches](options.html#opt-documentation.man.generateCaches) has been added to automatically generate the `man-db` caches, which are needed by utilities like `whatis` and `apropos`. The caches are generated during the build of the NixOS configuration: since this can be expensive when a large number of packages are installed, the feature is disabled by default. + + - `services.postfix.sslCACert` was replaced by `services.postfix.tlsTrustedAuthorities` which now defaults to system certificate authorities. + + - The various documented workarounds to use steam have been converted to a module. `programs.steam.enable` enables steam, controller support and the workarounds. + + - Support for built-in LCDs in various pieces of Logitech hardware (keyboards and USB speakers). `hardware.logitech.lcd.enable` enables support for all hardware supported by the [g15daemon project](https://sourceforge.net/projects/g15daemon/). + + - The GRUB module gained support for basic password protection, which allows to restrict non-default entries in the boot menu to one or more users. The users and passwords are defined via the option `boot.loader.grub.users`. Note: Password support is only available in GRUB version 2. + +- NixOS module changes: + + - The NixOS module system now supports freeform modules as a mix between `types.attrsOf` and `types.submodule`. These allow you to explicitly declare a subset of options while still permitting definitions without an associated option. See [](#sec-freeform-modules) for how to use them. + + - Following its deprecation in 20.03, the Perl NixOS test driver has been removed. All remaining tests have been ported to the Python test framework. Code outside nixpkgs using `make-test.nix` or `testing.nix` needs to be ported to `make-test-python.nix` and `testing-python.nix` respectively. + + - Subordinate GID and UID mappings are now set up automatically for all normal users.

Before you upgrade, it would be best to take a backup of your database. For MariaDB Galera Cluster, see [Upgrading from MariaDB 10.3 to MariaDB 10.4 with Galera Cluster](https://mariadb.com/kb/en/upgrading-from-mariadb-103-to-mariadb-104-with-galera-cluster/) instead. Before doing the upgrade read [Incompatible Changes Between 10.3 and 10.4](https://mariadb.com/kb/en/upgrading-from-mariadb-103-to-mariadb-104/#incompatible-changes-between-103-and-104). After the upgrade you will need to run `mysql_upgrade`. MariaDB 10.4 introduces a number of changes to the authentication process, intended to make things easier and more intuitive. See [Authentication from MariaDB 10.4](https://mariadb.com/kb/en/authentication-from-mariadb-104/). unix_socket auth plugin does not use a password, and uses the connecting user\'s UID instead. When a new MariaDB data directory is initialized, two MariaDB users are created and can be used with new unix_socket auth plugin, as well as traditional mysql_native_password plugin: root\@localhost and mysql\@localhost. To actually use the traditional mysql_native_password plugin method, one must run the following: + + ```nix + { + services.mysql.initialScript = pkgs.writeText "mariadb-init.sql" '' + ALTER USER root@localhost IDENTIFIED VIA mysql_native_password USING PASSWORD("verysecret"); + ''; + } + ``` + + When MariaDB data directory is just upgraded (not initialized), the users are not created or modified. + +- MySQL server is now started with additional systemd sandbox/hardening options for better security. The PrivateTmp, ProtectHome, and ProtectSystem options may be problematic when MySQL is attempting to read from or write to your filesystem anywhere outside of its own state directory, for example when calling `LOAD DATA INFILE or SELECT * INTO OUTFILE`. In this scenario a variant of the following may be required: - allow MySQL to read from /home and /tmp directories when using `LOAD DATA INFILE` + + ```nix + { + systemd.services.mysql.serviceConfig.ProtectHome = lib.mkForce "read-only"; + } + ``` + + \- allow MySQL to write to custom folder `/var/data` when using `SELECT * INTO OUTFILE`, assuming the mysql user has write access to `/var/data` + + ```nix + { + systemd.services.mysql.serviceConfig.ReadWritePaths = [ "/var/data" ]; + } + ``` + + The MySQL service no longer runs its `systemd` service startup script as `root` anymore. A dedicated non `root` super user account is required for operation. This means users with an existing MySQL or MariaDB database server are required to run the following SQL statements as a super admin user before upgrading: + + ```SQL + CREATE USER IF NOT EXISTS 'mysql'@'localhost' identified with unix_socket; + GRANT ALL PRIVILEGES ON *.* TO 'mysql'@'localhost' WITH GRANT OPTION; + ``` + + If you use MySQL instead of MariaDB please replace `unix_socket` with `auth_socket`. If you have changed the value of [services.mysql.user](options.html#opt-services.mysql.user) from the default of `mysql` to a different user please change `'mysql'@'localhost'` to the corresponding user instead. + +- Zabbix now defaults to 5.0, updated from 4.4. Please carefully read through [the upgrade guide](https://www.zabbix.com/documentation/current/manual/installation/upgrade/sources) and apply any changes required. Be sure to take special note of the section on [enabling extended range of numeric (float) values](https://www.zabbix.com/documentation/current/manual/installation/upgrade_notes_500#enabling_extended_range_of_numeric_float_values) as you will need to apply this database migration manually. + + If you are using Zabbix Server with a MySQL or MariaDB database you should note that using a character set of `utf8` and a collate of `utf8_bin` has become mandatory with this release. See the upstream [issue](https://support.zabbix.com/browse/ZBX-17357) for further discussion. Before upgrading you should check the character set and collation used by your database and ensure they are correct: + + ```SQL + SELECT + default_character_set_name, + default_collation_name + FROM + information_schema.schemata + WHERE + schema_name = 'zabbix'; + ``` + + If these values are not correct you should take a backup of your database and convert the character set and collation as required. Here is an [example](https://www.zabbix.com/forum/zabbix-help/396573-reinstall-after-upgrade?p=396891#post396891) of how to do so, taken from the Zabbix forums: + + ```SQL + ALTER DATABASE `zabbix` DEFAULT CHARACTER SET utf8 COLLATE utf8_bin; + + -- the following will produce a list of SQL commands you should subsequently execute + SELECT CONCAT("ALTER TABLE ", TABLE_NAME," CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;") AS ExecuteTheString + FROM information_schema.`COLUMNS` + WHERE table_schema = "zabbix" AND COLLATION_NAME = "utf8_general_ci"; + ``` + +- maxx package removed along with `services.xserver.desktopManager.maxx` module. Please migrate to cdesktopenv and `services.xserver.desktopManager.cde` module. + +- The [matrix-synapse](options.html#opt-services.matrix-synapse.enable) module no longer includes optional dependencies by default, they have to be added through the [plugins](options.html#opt-services.matrix-synapse.plugins) option. + +- `buildGoModule` now internally creates a vendor directory in the source tree for downloaded modules instead of using go\'s [module proxy protocol](https://golang.org/cmd/go/#hdr-Module_proxy_protocol). This storage format is simpler and therefore less likely to break with future versions of go. As a result `buildGoModule` switched from `modSha256` to the `vendorSha256` attribute to pin fetched version data. + +- Grafana is now built without support for phantomjs by default. Phantomjs support has been [deprecated in Grafana](https://grafana.com/docs/grafana/latest/guides/whats-new-in-v6-4/) and the phantomjs project is [currently unmaintained](https://github.com/ariya/phantomjs/issues/15344#issue-302015362). It can still be enabled by providing `phantomJsSupport = true` to the package instantiation: + + ```nix + { + services.grafana.package = pkgs.grafana.overrideAttrs (oldAttrs: rec { + phantomJsSupport = true; + }); + } + ``` + +- The [supybot](options.html#opt-services.supybot.enable) module now uses `/var/lib/supybot` as its default [stateDir](options.html#opt-services.supybot.stateDir) path if `stateVersion` is 20.09 or higher. It also enables a number of [systemd sandboxing options](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Sandboxing) which may possibly interfere with some plugins. If this is the case you can disable the options through attributes in `systemd.services.supybot.serviceConfig`. + +- The `security.duosec.skey` option, which stored a secret in the nix store, has been replaced by a new [security.duosec.secretKeyFile](options.html#opt-security.duosec.secretKeyFile) option for better security. + + `security.duosec.ikey` has been renamed to [security.duosec.integrationKey](options.html#opt-security.duosec.integrationKey). + +- `vmware` has been removed from the `services.x11.videoDrivers` defaults. For VMWare guests set `virtualisation.vmware.guest.enable` to `true` which will include the appropriate drivers. + +- The initrd SSH support now uses OpenSSH rather than Dropbear to allow the use of Ed25519 keys and other OpenSSH-specific functionality. Host keys must now be in the OpenSSH format, and at least one pre-generated key must be specified. + + If you used the `boot.initrd.network.ssh.host*Key` options, you\'ll get an error explaining how to convert your host keys and migrate to the new `boot.initrd.network.ssh.hostKeys` option. Otherwise, if you don\'t have any host keys set, you\'ll need to generate some; see the `hostKeys` option documentation for instructions. + +- Since this release there\'s an easy way to customize your PHP install to get a much smaller base PHP with only wanted extensions enabled. See the following snippet installing a smaller PHP with the extensions `imagick`, `opcache`, `pdo` and `pdo_mysql` loaded: + + ```nix + { + environment.systemPackages = [ + (pkgs.php.withExtensions + ({ all, ... }: with all; [ + imagick + opcache + pdo + pdo_mysql + ]) + ) + ]; + } + ``` + + The default `php` attribute hasn\'t lost any extensions. The `opcache` extension has been added. All upstream PHP extensions are available under php.extensions.\<name?\>. + + All PHP `config` flags have been removed for the following reasons: + +- The updated `php` attribute is now easily customizable to your liking by using `php.withExtensions` or `php.buildEnv` instead of writing config files or changing configure flags. + +- The remaining configuration flags can now be set directly on the `php` attribute. For example, instead of + + ```nix + { + php.override { + config.php.embed = true; + config.php.apxs2 = false; + } + } + ``` + + you should now write + + ```nix + { + php.override { + embedSupport = true; + apxs2Support = false; + } + } + ``` + +- The ACME module has been overhauled for simplicity and maintainability. Cert generation now implicitly uses the `acme` user, and the `security.acme.certs._name_.user` option has been removed. Instead, certificate access from other services is now managed through group permissions. The module no longer runs lego twice under certain conditions, and will correctly renew certificates if their configuration is changed. Services which reload nginx and httpd after certificate renewal are now properly configured too so you no longer have to do this manually if you are using HTTPS enabled virtual hosts. A mechanism for regenerating certs on demand has also been added and documented. + +- Gollum received a major update to version 5.x and you may have to change some links in your wiki when migrating from gollum 4.x. More information can be found [here](https://github.com/gollum/gollum/wiki/5.0-release-notes#migrating-your-wiki). + +- Deluge 2.x was added and is used as default for new NixOS installations where stateVersion is \>= 20.09. If you are upgrading from a previous NixOS version, you can set `service.deluge.package = pkgs.deluge-2_x` to upgrade to Deluge 2.x and migrate the state to the new format. Be aware that backwards state migrations are not supported by Deluge. + +- Nginx web server now starting with additional sandbox/hardening options. By default, write access to `/var/log/nginx` and `/var/cache/nginx` is allowed. To allow writing to other folders, use `systemd.services.nginx.serviceConfig.ReadWritePaths` + + ```nix + { + systemd.services.nginx.serviceConfig.ReadWritePaths = [ "/var/www" ]; + } + ``` + + Nginx is also started with the systemd option `ProtectHome = mkDefault true;` which forbids it to read anything from `/home`, `/root` and `/run/user` (see [ProtectHome docs](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#ProtectHome=) for details). If you require serving files from home directories, you may choose to set e.g. + + ```nix + { + systemd.services.nginx.serviceConfig.ProtectHome = "read-only"; + } + ``` + +- The NixOS options `nesting.clone` and `nesting.children` have been deleted, and replaced with named [specialisation](options.html#opt-specialisation) configurations. + + Replace a `nesting.clone` entry with: + + ```nix + { + specialisation.example-sub-configuration = { + configuration = { + ... + }; + }; + ``` + + Replace a `nesting.children` entry with: + + ```nix + { + specialisation.example-sub-configuration = { + inheritParentConfig = false; + configuration = { + ... + }; + }; + ``` + + To switch to a specialised configuration at runtime you need to run: + + ```ShellSession + $ sudo /run/current-system/specialisation/example-sub-configuration/bin/switch-to-configuration test + ``` + + Before you would have used: + + ```ShellSession + $ sudo /run/current-system/fine-tune/child-1/bin/switch-to-configuration test + ``` + +- The Nginx log directory has been moved to `/var/log/nginx`, the cache directory to `/var/cache/nginx`. The option `services.nginx.stateDir` has been removed. + +- The httpd web server previously started its main process as root privileged, then ran worker processes as a less privileged identity user. This was changed to start all of httpd as a less privileged user (defined by [services.httpd.user](options.html#opt-services.httpd.user) and [services.httpd.group](options.html#opt-services.httpd.group)). As a consequence, all files that are needed for httpd to run (included configuration fragments, SSL certificates and keys, etc.) must now be readable by this less privileged user/group. + + The default value for [services.httpd.mpm](options.html#opt-services.httpd.mpm) has been changed from `prefork` to `event`. Along with this change the default value for [services.httpd.virtualHosts.\<name\>.http2](options.html#opt-services.httpd.virtualHosts) has been set to `true`. + +- The `systemd-networkd` option `systemd.network.networks.<name>.dhcp.CriticalConnection` has been removed following upstream systemd\'s deprecation of the same. It is recommended to use `systemd.network.networks.<name>.networkConfig.KeepConfiguration` instead. See systemd.network 5 for details. + +- The `systemd-networkd` option `systemd.network.networks._name_.dhcpConfig` has been renamed to [systemd.network.networks._name_.dhcpV4Config](options.html#opt-systemd.network.networks._name_.dhcpV4Config) following upstream systemd\'s documentation change. See systemd.network 5 for details. + +- In the `picom` module, several options that accepted floating point numbers encoded as strings (for example [services.picom.activeOpacity](options.html#opt-services.picom.activeOpacity)) have been changed to the (relatively) new native `float` type. To migrate your configuration simply remove the quotes around the numbers. + +- When using `buildBazelPackage` from Nixpkgs, `flat` hash mode is now used for dependencies instead of `recursive`. This is to better allow using hashed mirrors where needed. As a result, these hashes will have changed. + +- The syntax of the PostgreSQL configuration file is now checked at build time. If your configuration includes a file inaccessible inside the build sandbox, set `services.postgresql.checkConfig` to `false`. + +- The rkt module has been removed, it was archived by upstream. + +- The [Bazaar](https://bazaar.canonical.com) VCS is unmaintained and, as consequence of the Python 2 EOL, the packages `bazaar` and `bazaarTools` were removed. Breezy, the backward compatible fork of Bazaar (see the [announcement](https://www.jelmer.uk/breezy-intro.html)), was packaged as `breezy` and can be used instead. + + Regarding Nixpkgs, `fetchbzr`, `nix-prefetch-bzr` and Bazaar support in Hydra will continue to work through Breezy. + +- In addition to the hostname, the fully qualified domain name (FQDN), which consists of `${networking.hostName}` and `${networking.domain}` is now added to `/etc/hosts`, to allow local FQDN resolution, as used by the `hostname --fqdn` command and other applications that try to determine the FQDN. These new entries take precedence over entries from the DNS which could cause regressions in some very specific setups. Additionally the hostname is now resolved to `127.0.0.2` instead of `127.0.1.1` to be consistent with what `nss-myhostname` (from systemd) returns. The old behaviour can e.g. be restored by using `networking.hosts = lib.mkForce { "127.0.1.1" = [ config.networking.hostName ]; };`. + +- The hostname (`networking.hostName`) must now be a valid DNS label (see RFC 1035, RFC 1123) and as such must not contain the domain part. This means that the hostname must start with a letter or digit, end with a letter or digit, and have as interior characters only letters, digits, and hyphen. The maximum length is 63 characters. Additionally it is recommended to only use lower-case characters. If (e.g. for legacy reasons) a FQDN is required as the Linux kernel network node hostname (`uname --nodename`) the option `boot.kernel.sysctl."kernel.hostname"` can be used as a workaround (but be aware of the 64 character limit). + +- The GRUB specific option `boot.loader.grub.extraInitrd` has been replaced with the generic option `boot.initrd.secrets`. This option creates a secondary initrd from the specified files, rather than using a manually created initrd file. Due to an existing bug with `boot.loader.grub.extraInitrd`, it is not possible to directly boot an older generation that used that option. It is still possible to rollback to that generation if the required initrd file has not been deleted. + +- The [DNSChain](https://github.com/okTurtles/dnschain) package and NixOS module have been removed from Nixpkgs as the software is unmaintained and can\'t be built. For more information see issue [\#89205](https://github.com/NixOS/nixpkgs/issues/89205). + +- In the `resilio` module, [services.resilio.httpListenAddr](options.html#opt-services.resilio.httpListenAddr) has been changed to listen to `[::1]` instead of `0.0.0.0`. + +- `sslh` has been updated to version `1.21`. The `ssl` probe must be renamed to `tls` in [services.sslh.appendConfig](options.html#opt-services.sslh.appendConfig). + +- Users of [OpenAFS 1.6](http://openafs.org) must upgrade their services to OpenAFS 1.8! In this release, the OpenAFS package version 1.6.24 is marked broken but can be used during transition to OpenAFS 1.8.x. Use the options `services.openafsClient.packages.module`, `services.openafsClient.packages.programs` and `services.openafsServer.package` to select a different OpenAFS package. OpenAFS 1.6 will be removed in the next release. The package `openafs` and the service options will then silently point to the OpenAFS 1.8 release. + + See also the OpenAFS [Administrator Guide](http://docs.openafs.org/AdminGuide/index.html) for instructions. Beware of the following when updating servers: + + - The storage format of the server key has changed and the key must be converted before running the new release. + + - When updating multiple database servers, turn off the database servers from the highest IP down to the lowest with resting periods in between. Start up in reverse order. Do not concurrently run database servers working with different OpenAFS releases! + + - Update servers first, then clients. + +- Radicale\'s default package has changed from 2.x to 3.x. An upgrade checklist can be found [here](https://github.com/Kozea/Radicale/blob/3.0.x/NEWS.md#upgrade-checklist). You can use the newer version in the NixOS service by setting the `package` to `radicale3`, which is done automatically if `stateVersion` is 20.09 or higher. + +- `udpt` experienced a complete rewrite from C++ to rust. The configuration format changed from ini to toml. The new configuration documentation can be found at [the official website](https://naim94a.github.io/udpt/config.html) and example configuration is packaged in `${udpt}/share/udpt/udpt.toml`. + +- We now have a unified [services.xserver.displayManager.autoLogin](options.html#opt-services.xserver.displayManager.autoLogin) option interface to be used for every display-manager in NixOS. + +- The `bitcoind` module has changed to multi-instance, using submodules. Therefore, it is now mandatory to name each instance. To use this new multi-instance config with an existing bitcoind data directory and user, you have to adjust the original config, e.g.: + + ```nix + { + services.bitcoind = { + enable = true; + extraConfig = "..."; + ... + }; + } + ``` + + To something similar: + + ```nix + { + services.bitcoind.mainnet = { + enable = true; + dataDir = "/var/lib/bitcoind"; + user = "bitcoin"; + extraConfig = "..."; + ... + }; + } + ``` + + The key settings are: + + - `dataDir` - to continue using the same data directory. + + - `user` - to continue using the same user so that bitcoind maintains access to its files. + +- Graylog introduced a change in the LDAP server certificate validation behaviour for version 3.3.3 which might break existing setups. When updating Graylog from a version before 3.3.3 make sure to check the Graylog [release info](https://www.graylog.org/post/announcing-graylog-v3-3-3) for information on how to avoid the issue. + +- The `dokuwiki` module has changed to multi-instance, using submodules. Therefore, it is now mandatory to name each instance. Moreover, forcing SSL by default has been dropped, so `nginx.forceSSL` and `nginx.enableACME` are no longer set to `true`. To continue using your service with the original SSL settings, you have to adjust the original config, e.g.: + + ```nix + { + services.dokuwiki = { + enable = true; + ... + }; + } + ``` + + To something similar: + + ```nix + { + services.dokuwiki."mywiki" = { + enable = true; + nginx = { + forceSSL = true; + enableACME = true; + }; + ... + }; + } + ``` + + The base package has also been upgraded to the 2020-07-29 \"Hogfather\" release. Plugins might be incompatible or require upgrading. + +- The [services.postgresql.dataDir](options.html#opt-services.postgresql.dataDir) option is now set to `"/var/lib/postgresql/${cfg.package.psqlSchema}"` regardless of your [system.stateVersion](options.html#opt-system.stateVersion). Users with an existing postgresql install that have a [system.stateVersion](options.html#opt-system.stateVersion) of `17.03` or below should double check what the value of their [services.postgresql.dataDir](options.html#opt-services.postgresql.dataDir) option is (`/var/db/postgresql`) and then explicitly set this value to maintain compatibility: + + ```nix + { + services.postgresql.dataDir = "/var/db/postgresql"; + } + ``` + + The postgresql module now expects there to be a database super user account called `postgres` regardless of your [system.stateVersion](options.html#opt-system.stateVersion). Users with an existing postgresql install that have a [system.stateVersion](options.html#opt-system.stateVersion) of `17.03` or below should run the following SQL statements as a database super admin user before upgrading: + + ```SQL + CREATE ROLE postgres LOGIN SUPERUSER; + ``` + +- The USBGuard module now removes options and instead hardcodes values for `IPCAccessControlFiles`, `ruleFiles`, and `auditFilePath`. Audit logs can be found in the journal. + +- The NixOS module system now evaluates option definitions more strictly, allowing it to detect a larger set of problems. As a result, what previously evaluated may not do so anymore. See [the PR that changed this](https://github.com/NixOS/nixpkgs/pull/82743#issuecomment-674520472) for more info. + +- For NixOS configuration options, the type `loaOf`, after its initial deprecation in release 20.03, has been removed. In NixOS and Nixpkgs options using this type have been converted to `attrsOf`. For more information on this change have look at these links: [issue \#1800](https://github.com/NixOS/nixpkgs/issues/1800), [PR \#63103](https://github.com/NixOS/nixpkgs/pull/63103). + +- `config.systemd.services.${name}.path` now returns a list of paths instead of a colon-separated string. + +- Caddy module now uses Caddy v2 by default. Caddy v1 can still be used by setting [services.caddy.package](options.html#opt-services.caddy.package) to `pkgs.caddy1`. + + New option [services.caddy.adapter](options.html#opt-services.caddy.adapter) has been added. + +- The [jellyfin](options.html#opt-services.jellyfin.enable) module will use and stay on the Jellyfin version `10.5.5` if `stateVersion` is lower than `20.09`. This is because significant changes were made to the database schema, and it is highly recommended to backup your instance before upgrading. After making your backup, you can upgrade to the latest version either by setting your `stateVersion` to `20.09` or higher, or set the `services.jellyfin.package` to `pkgs.jellyfin`. If you do not wish to upgrade Jellyfin, but want to change your `stateVersion`, you can set the value of `services.jellyfin.package` to `pkgs.jellyfin_10_5`. + +- The `security.rngd` service is now disabled by default. This choice was made because there\'s krngd in the linux kernel space making it (for most usecases) functionally redundent. + +- The `hardware.nvidia.optimus_prime.enable` service has been renamed to `hardware.nvidia.prime.sync.enable` and has many new enhancements. Related nvidia prime settings may have also changed. + +- The package nextcloud17 has been removed and nextcloud18 was marked as insecure since both of them will [ will be EOL (end of life) within the lifetime of 20.09](https://docs.nextcloud.com/server/19/admin_manual/release_schedule.html). + + It\'s necessary to upgrade to nextcloud19: + + - From nextcloud17, you have to upgrade to nextcloud18 first as Nextcloud doesn\'t allow going multiple major revisions forward in a single upgrade. This is possible by setting [services.nextcloud.package](options.html#opt-services.nextcloud.package) to nextcloud18. + + - From nextcloud18, it\'s possible to directly upgrade to nextcloud19 by setting [services.nextcloud.package](options.html#opt-services.nextcloud.package) to nextcloud19. + +- The GNOME desktop manager no longer default installs gnome3.epiphany. It was chosen to do this as it has a usability breaking issue (see issue [\#98819](https://github.com/NixOS/nixpkgs/issues/98819)) that makes it unsuitable to be a default app. + + ::: {.note} + Issue [\#98819](https://github.com/NixOS/nixpkgs/issues/98819) is now fixed and gnome3.epiphany is once again installed by default. + ::: + +- If you want to manage the configuration of wpa_supplicant outside of NixOS you must ensure that none of [networking.wireless.networks](options.html#opt-networking.wireless.networks), [networking.wireless.extraConfig](options.html#opt-networking.wireless.extraConfig) or [networking.wireless.userControlled.enable](options.html#opt-networking.wireless.userControlled.enable) is being used or `true`. Using any of those options will cause wpa_supplicant to be started with a NixOS generated configuration file instead of your own. + +## Other Notable Changes {#sec-release-20.09-notable-changes} + +- SD images are now compressed by default using `zstd`. The compression for ISO images has also been changed to `zstd`, but ISO images are still not compressed by default. + +- `services.journald.rateLimitBurst` was updated from `1000` to `10000` to follow the new upstream systemd default. + +- The notmuch package moves its emacs-related binaries and emacs lisp files to a separate output. They\'re not part of the default `out` output anymore - if you relied on the `notmuch-emacs-mua` binary or the emacs lisp files, access them via the `notmuch.emacs` output. + +- Device tree overlay support was improved in [\#79370](https://github.com/NixOS/nixpkgs/pull/79370) and now uses [hardware.deviceTree.kernelPackage](options.html#opt-hardware.deviceTree.kernelPackage) instead of `hardware.deviceTree.base`. [hardware.deviceTree.overlays](options.html#opt-hardware.deviceTree.overlays) configuration was extended to support `.dts` files with symbols. Device trees can now be filtered by setting [hardware.deviceTree.filter](options.html#opt-hardware.deviceTree.filter) option. + +- The default output of `buildGoPackage` is now `$out` instead of `$bin`. + +- `buildGoModule` `doCheck` now defaults to `true`. + +- Packages built using `buildRustPackage` now use `release` mode for the `checkPhase` by default. + + Please note that Rust packages utilizing a custom build/install procedure (e.g. by using a `Makefile`) or test suites that rely on the structure of the `target/` directory may break due to those assumptions. For further information, please read the Rust section in the Nixpkgs manual. + +- The cc- and binutils-wrapper\'s \"infix salt\" and `_BUILD_` and `_TARGET_` user infixes have been replaced with with a \"suffix salt\" and suffixes and `_FOR_BUILD` and `_FOR_TARGET`. This matches the autotools convention for env vars which standard for these things, making interfacing with other tools easier. + +- Additional Git documentation (HTML and text files) is now available via the `git-doc` package. + +- Default algorithm for ZRAM swap was changed to `zstd`. + +- The installer now enables sshd by default. This improves installation on headless machines especially ARM single-board-computer. To login through ssh, either a password or an ssh key must be set for the root user or the nixos user. + +- The scripted networking system now uses `.link` files in `/etc/systemd/network` to configure mac address and link MTU, instead of the sometimes buggy `network-link-*` units, which have been removed. Bringing the interface up has been moved to the beginning of the `network-addresses-*` unit. Note this doesn\'t require `systemd-networkd` - it\'s udev that parses `.link` files. Extra care needs to be taken in the presence of [legacy udev rules](https://wiki.debian.org/NetworkInterfaceNames#THE_.22PERSISTENT_NAMES.22_SCHEME) to rename interfaces, as MAC Address and MTU defined in these options can only match on the original link name. In such cases, you most likely want to create a `10-*.link` file through [systemd.network.links](options.html#opt-systemd.network.links) and set both name and MAC Address / MTU there. + +- Grafana received a major update to version 7.x. A plugin is now needed for image rendering support, and plugins must now be signed by default. More information can be found [in the Grafana documentation](https://grafana.com/docs/grafana/latest/installation/upgrading/#upgrading-to-v7-0). + +- The `hardware.u2f` module, which was installing udev rules was removed, as udev gained native support to handle FIDO security tokens. + +- The `services.transmission` module was enhanced with the new options: [services.transmission.credentialsFile](options.html#opt-services.transmission.credentialsFile), [services.transmission.openFirewall](options.html#opt-services.transmission.openFirewall), and [services.transmission.performanceNetParameters](options.html#opt-services.transmission.performanceNetParameters). + + `transmission-daemon` is now started with additional systemd sandbox/hardening options for better security. Please [report](https://github.com/NixOS/nixpkgs/issues) any use case where this is not working well. In particular, the `RootDirectory` option newly set forbids uploading or downloading a torrent outside of the default directory configured at [settings.download-dir](options.html#opt-services.transmission.settings). If you really need Transmission to access other directories, you must include those directories into the `BindPaths` of the service: + + ```nix + { + systemd.services.transmission.serviceConfig.BindPaths = [ "/path/to/alternative/download-dir" ]; + } + ``` + + Also, connection to the RPC (Remote Procedure Call) of `transmission-daemon` is now only available on the local network interface by default. Use: + + ```nix + { + services.transmission.settings.rpc-bind-address = "0.0.0.0"; + } + ``` + + to get the previous behavior of listening on all network interfaces. + +- With this release `systemd-networkd` (when enabled through [networking.useNetworkd](options.html#opt-networking.useNetworkd)) has it\'s netlink socket created through a `systemd.socket` unit. This gives us control over socket buffer sizes and other parameters. For larger setups where networkd has to create a lot of (virtual) devices the default buffer size (currently 128MB) is not enough. + + On a machine with \>100 virtual interfaces (e.g., wireguard tunnels, VLANs, ...), that all have to be brought up during system startup, the receive buffer size will spike for a brief period. Eventually some of the message will be dropped since there is not enough (permitted) buffer space available. + + By having `systemd-networkd` start with a netlink socket created by `systemd` we can configure the `ReceiveBufferSize=` parameter in the socket options (i.e. `systemd.sockets.systemd-networkd.socketOptions.ReceiveBufferSize`) without recompiling `systemd-networkd`. + + Since the actual memory requirements depend on hardware, timing, exact configurations etc. it isn\'t currently possible to infer a good default from within the NixOS module system. Administrators are advised to monitor the logs of `systemd-networkd` for `rtnl: kernel receive buffer overrun` spam and increase the memory limit as they see fit. + + Note: Increasing the `ReceiveBufferSize=` doesn\'t allocate any memory. It just increases the upper bound on the kernel side. The memory allocation depends on the amount of messages that are queued on the kernel side of the netlink socket. + +- Specifying [mailboxes](options.html#opt-services.dovecot2.mailboxes) in the dovecot2 module as a list is deprecated and will break eval in 21.05. Instead, an attribute-set should be specified where the `name` should be the key of the attribute. + + This means that a configuration like this + + ```nix + { + services.dovecot2.mailboxes = [ + { name = "Junk"; + auto = "create"; + } + ]; + } + ``` + + should now look like this: + + ```nix + { + services.dovecot2.mailboxes = { + Junk.auto = "create"; + }; + } + ``` + +- netbeans was upgraded to 12.0 and now defaults to OpenJDK 11. This might cause problems if your projects depend on packages that were removed in Java 11. + +- nextcloud has been updated to [v19](https://nextcloud.com/blog/nextcloud-hub-brings-productivity-to-home-office/). + + If you have an existing installation, please make sure that you\'re on nextcloud18 before upgrading to nextcloud19 since Nextcloud doesn\'t support upgrades across multiple major versions. + +- The `nixos-run-vms` script now deletes the previous run machines states on test startup. You can use the `--keep-vm-state` flag to match the previous behaviour and keep the same VM state between different test runs. + +- The [nix.buildMachines](options.html#opt-nix.buildMachines) option is now type-checked. There are no functional changes, however this may require updating some configurations to use correct types for all attributes. + +- The `fontconfig` module stopped generating config and cache files for fontconfig 2.10.x, the `/etc/fonts/fonts.conf` now belongs to the latest fontconfig, just like on other Linux distributions, and we will [no longer](https://github.com/NixOS/nixpkgs/pull/95358) be versioning the config directories. + + Fontconfig 2.10.x was removed from Nixpkgs since it hasn't been used in any Nixpkgs package for years now. + +- Nginx module `nginxModules.fastcgi-cache-purge` renamed to official name `nginxModules.cache-purge`. Nginx module `nginxModules.ngx_aws_auth` renamed to official name `nginxModules.aws-auth`. + +- The option `defaultPackages` was added. It installs the packages perl, rsync and strace for now. They were added unconditionally to `systemPackages` before, but are not strictly necessary for a minimal NixOS install. You can set it to an empty list to have a more minimal system. Be aware that some functionality might still have an impure dependency on those packages, so things might break. + +- The `undervolt` option no longer needs to apply its settings every 30s. If they still become undone, open an issue and restore the previous behaviour using `undervolt.useTimer`. + +- Agda has been heavily reworked. + + - `agda.mkDerivation` has been heavily changed and is now located at agdaPackages.mkDerivation. + + - New top-level packages agda and `agda.withPackages` have been added, the second of which sets up agda with access to chosen libraries. + + - All agda libraries now live under `agdaPackages`. + + - Many broken libraries have been removed. + + See the [new documentation](https://nixos.org/nixpkgs/manual/#agda) for more information. + +- The `deepin` package set has been removed from nixpkgs. It was a work in progress to package the [Deepin Desktop Environment (DDE)](https://www.deepin.org/en/dde/), including libraries, tools and applications, and it was still missing a service to launch the desktop environment. It has shown to no longer be a feasible goal due to reasons discussed in [issue \#94870](https://github.com/NixOS/nixpkgs/issues/94870). The package `netease-cloud-music` has also been removed, as it depends on libraries from deepin. + +- The `opendkim` module now uses systemd sandboxing features to limit the exposure of the system towards the opendkim service. + +- Kubernetes has been upgraded to 1.19.1, which also means that the golang version to build it has been bumped to 1.15. This may have consequences for your existing clusters and their certificates. Please consider [ the release notes for Kubernetes 1.19 carefully ](https://relnotes.k8s.io/?markdown=93264) before upgrading. + +- For AMD GPUs, Vulkan can now be used by adding `amdvlk` to `hardware.opengl.extraPackages`. + +- Similarly, still for AMD GPUs, the ROCm OpenCL stack can now be used by adding `rocm-opencl-icd` to `hardware.opengl.extraPackages`. + +## Contributions {#sec-release-20.09-contributions} + +I, Jonathan Ringer, would like to thank the following individuals for their work on nixpkgs.

Builds with optimizations enabled are not reproducible. Optimizations can now be enabled with an option. + +- The linux_latest kernel was updated to the 5.13 series. It currently is not officially supported for use with the zfs filesystem. If you use zfs, you should use a different kernel version (either the LTS kernel, or track a specific one). + +## New Services {#sec-release-21.05-new-services} + +The following new services were added since the last release: + +- [GNURadio](https://www.gnuradio.org/) 3.8 and 3.9 were [finally](https://github.com/NixOS/nixpkgs/issues/82263) packaged, along with a rewrite to the Nix expressions, allowing users to override the features upstream supports selecting to compile or not to. Additionally, the attribute `gnuradio` (3.9), `gnuradio3_8` and `gnuradio3_7` now point to an externally wrapped by default derivations, that allow you to also add \`extraPythonPackages\` to the Python interpreter used by GNURadio. Missing environmental variables needed for operational GUI were also added ([\#75478](https://github.com/NixOS/nixpkgs/issues/75478)). + +- [Keycloak](https://www.keycloak.org/), an open source identity and access management server with support for [OpenID Connect](https://openid.net/connect/), [OAUTH 2.0](https://oauth.net/2/) and [SAML 2.0](https://en.wikipedia.org/wiki/SAML_2.0). + + See the [Keycloak section of the NixOS manual](#module-services-keycloak) for more information. + +- [services.samba-wsdd.enable](options.html#opt-services.samba-wsdd.enable) Web Services Dynamic Discovery host daemon + +- [Discourse](https://www.discourse.org/), a modern and open source discussion platform. + + See the [Discourse section of the NixOS manual](#module-services-discourse) for more information. + +- [services.nebula.networks](options.html#opt-services.nebula.networks) [Nebula VPN](https://github.com/slackhq/nebula) + +## Backward Incompatibilities {#sec-release-21.05-incompatibilities} + +When upgrading from a previous release, please be aware of the following incompatible changes: + +- GNOME desktop environment was upgraded to 40, see the release notes for [40.0](https://help.gnome.org/misc/release-notes/40.0/) and [3.38](https://help.gnome.org/misc/release-notes/3.38/). The `gnome3` attribute set has been renamed to `gnome` and so have been the NixOS options. + +- If you are using `services.udev.extraRules` to assign custom names to network interfaces, this may stop working due to a change in the initialisation of dhcpcd and systemd networkd. To avoid this, either move them to `services.udev.initrdRules` or see the new [Assigning custom names](#sec-custom-ifnames) section of the NixOS manual for an example using networkd links. + +- The `security.hideProcessInformation` module has been removed. It was broken since the switch to cgroups-v2. + +- The `linuxPackages.ati_drivers_x11` kernel modules have been removed. The drivers only supported kernels prior to 4.2, and thus have become obsolete. + +- The `systemConfig` kernel parameter is no longer added to boot loader entries. It has been unused since September 2010, but if do have a system generation from that era, you will now be unable to boot into them. + +- `systemd-journal2gelf` no longer parses json and expects the receiving system to handle it. How to achieve this with Graylog is described in this [GitHub issue](https://github.com/parse-nl/SystemdJournal2Gelf/issues/10). + +- If the `services.dbus` module is enabled, then the user D-Bus session is now always socket activated. The associated options `services.dbus.socketActivated` and `services.xserver.startDbusSession` have therefore been removed and you will receive a warning if they are present in your configuration. This change makes the user D-Bus session available also for non-graphical logins. + +- The `networking.wireless.iwd` module now installs the upstream-provided 80-iwd.link file, which sets the NamePolicy= for all wlan devices to \"keep kernel\", to avoid race conditions between iwd and networkd. If you don\'t want this, you can set `systemd.network.links."80-iwd" = lib.mkForce {}`. + +- `rubyMinimal` was removed due to being unused and unusable. The default ruby interpreter includes JIT support, which makes it reference it\'s compiler. Since JIT support is probably needed by some Gems, it was decided to enable this feature with all cc references by default, and allow to build a Ruby derivation without references to cc, by setting `jitSupport = false;` in an overlay. See [\#90151](https://github.com/NixOS/nixpkgs/pull/90151) for more info. + +- Setting `services.openssh.authorizedKeysFiles` now also affects which keys `security.pam.enableSSHAgentAuth` will use. WARNING: If you are using these options in combination do make sure that any key paths you use are present in `services.openssh.authorizedKeysFiles`! + +- The option `fonts.enableFontDir` has been renamed to [fonts.fontDir.enable](options.html#opt-fonts.fontDir.enable). The path of font directory has also been changed to `/run/current-system/sw/share/X11/fonts`, for consistency with other X11 resources. + +- A number of options have been renamed in the kicad interface. `oceSupport` has been renamed to `withOCE`, `withOCCT` has been renamed to `withOCC`, `ngspiceSupport` has been renamed to `withNgspice`, and `scriptingSupport` has been renamed to `withScripting`. Additionally, `kicad/base.nix` no longer provides default argument values since these are provided by `kicad/default.nix`. + +- The socket for the `pdns-recursor` module was moved from `/var/lib/pdns-recursor` to `/run/pdns-recursor` to match upstream. + +- Paperwork was updated to version 2. The on-disk format slightly changed, and it is not possible to downgrade from Paperwork 2 back to Paperwork 1.3. Back your documents up before upgrading. See [this thread](https://forum.openpaper.work/t/paperwork-2-0/112/5) for more details. + +- PowerDNS has been updated from `4.2.x` to `4.3.x`. Please be sure to review the [Upgrade Notes](https://doc.powerdns.com/authoritative/upgrading.html#x-to-4-3-0) provided by upstream before upgrading. Worth specifically noting is that the service now runs entirely as a dedicated `pdns` user, instead of starting as `root` and dropping privileges, as well as the default `socket-dir` location changing from `/var/lib/powerdns` to `/run/pdns`. + +- The `mediatomb` service is now using by default the new and maintained fork `gerbera` package instead of the unmaintained `mediatomb` package. If you want to keep the old behavior, you must declare it with: + + ```nix + { + services.mediatomb.package = pkgs.mediatomb; + } + ``` + + One new option `openFirewall` has been introduced which defaults to false. If you relied on the service declaration to add the firewall rules itself before, you should now declare it with: + + ```nix + { + services.mediatomb.openFirewall = true; + } + ``` + +- xfsprogs was update from 4.19 to 5.11. It now enables reflink support by default on filesystem creation. Support for reflinks was added with an experimental status to kernel 4.9 and deemed stable in kernel 4.16. If you want to be able to mount XFS filesystems created with this release of xfsprogs on kernel releases older than those, you need to format them with `mkfs.xfs -m reflink=0`. + +- The uWSGI server is now built with POSIX capabilities. As a consequence, root is no longer required in emperor mode and the service defaults to running as the unprivileged `uwsgi` user. Any additional capability can be added via the new option [services.uwsgi.capabilities](options.html#opt-services.uwsgi.capabilities). The previous behaviour can be restored by setting: + + ```nix + { + services.uwsgi.user = "root"; + services.uwsgi.group = "root"; + services.uwsgi.instance = + { + uid = "uwsgi"; + gid = "uwsgi"; + }; + } + ``` + + Another incompatibility from the previous release is that vassals running under a different user or group need to use `immediate-{uid,gid}` instead of the usual `uid,gid` options. + +- btc1 has been abandoned upstream, and removed. + +- cpp_ethereum (aleth) has been abandoned upstream, and removed. + +- riak-cs package removed along with `services.riak-cs` module. + +- stanchion package removed along with `services.stanchion` module. + +- mutt has been updated to a new major version (2.x), which comes with some backward incompatible changes that are described in the [release notes for Mutt 2.0](http://www.mutt.org/relnotes/2.0/). + +- `vim` and `neovim` switched to Python 3, dropping all Python 2 support. + +- [networking.wireguard.interfaces.\<name\>.generatePrivateKeyFile](options.html#opt-networking.wireguard.interfaces), which is off by default, had a `chmod` race condition fixed. As an aside, the parent directory\'s permissions were widened, and the key files were made owner-writable. This only affects newly created keys. However, if the exact permissions are important for your setup, read [\#121294](https://github.com/NixOS/nixpkgs/pull/121294). + +- [boot.zfs.forceImportAll](options.html#opt-boot.zfs.forceImportAll) previously did nothing, but has been fixed. However its default has been changed to `false` to preserve the existing default behaviour. If you have this explicitly set to `true`, please note that your non-root pools will now be forcibly imported. + +- openafs now points to openafs_1_8, which is the new stable release. OpenAFS 1.6 was removed. + +- The WireGuard module gained a new option `networking.wireguard.interfaces.<name>.peers.*.dynamicEndpointRefreshSeconds` that implements refreshing the IP of DNS-based endpoints periodically (which WireGuard itself [cannot do](https://lists.zx2c4.com/pipermail/wireguard/2017-November/002028.html)). + +- MariaDB has been updated to 10.5. Before you upgrade, it would be best to take a backup of your database and read [ Incompatible Changes Between 10.4 and 10.5](https://mariadb.com/kb/en/upgrading-from-mariadb-104-to-mariadb-105/#incompatible-changes-between-104-and-105). After the upgrade you will need to run `mysql_upgrade`. + +- The TokuDB storage engine dropped in mariadb 10.5 and removed in mariadb 10.6. It is recommended to switch to RocksDB. See also [TokuDB](https://mariadb.com/kb/en/tokudb/) and [MDEV-19780: Remove the TokuDB storage engine](https://jira.mariadb.org/browse/MDEV-19780). + +- The `openldap` module now has support for OLC-style configuration, users of the `configDir` option may wish to migrate. If you continue to use `configDir`, ensure that `olcPidFile` is set to `/run/slapd/slapd.pid`. + + As a result, `extraConfig` and `extraDatabaseConfig` are removed. To help with migration, you can convert your `slapd.conf` file to OLC configuration with the following script (find the location of this configuration file by running `systemctl status openldap`, it is the `-f` option. + + ```ShellSession + $ TMPDIR=$(mktemp -d) + $ slaptest -f /path/to/slapd.conf -F $TMPDIR + $ slapcat -F $TMPDIR -n0 -H 'ldap:///???(!(objectClass=olcSchemaConfig))' + ``` + + This will dump your current configuration in LDIF format, which should be straightforward to convert into Nix settings. This does not show your schema configuration, as this is unnecessarily verbose for users of the default schemas and `slaptest` is buggy with schemas directly in the config file. + +- Amazon EC2 and OpenStack Compute (nova) images now re-fetch instance meta data and user data from the instance metadata service (IMDS) on each boot. For example: stopping an EC2 instance, changing its user data, and restarting the instance will now cause it to fetch and apply the new user data. + + ::: {.warning} + Specifically, `/etc/ec2-metadata` is re-populated on each boot. Some NixOS scripts that read from this directory are guarded to only run if the files they want to manipulate do not already exist, and so will not re-apply their changes if the IMDS response changes. Examples: `root`\'s SSH key is only added if `/root/.ssh/authorized_keys` does not exist, and SSH host keys are only set from user data if they do not exist in `/etc/ssh`. + ::: + +- The `rspamd` services is now sandboxed. It is run as a dynamic user instead of root, so secrets and other files may have to be moved or their permissions may have to be fixed. The sockets are now located in `/run/rspamd` instead of `/run`. + +- Enabling the Tor client no longer silently also enables and configures Privoxy, and the `services.tor.client.privoxy.enable` option has been removed. To enable Privoxy, and to configure it to use Tor\'s faster port, use the following configuration: + + ```nix + { + opt-services.privoxy.enable = true; + opt-services.privoxy.enableTor = true; + } + ``` + +- The `services.tor` module has a new exhaustively typed [services.tor.settings](options.html#opt-services.tor.settings) option following RFC 0042; backward compatibility with old options has been preserved when aliasing was possible. The corresponding systemd service has been hardened, but there is a chance that the service still requires more permissions, so please report any related trouble on the bugtracker. Onion services v3 are now supported in [services.tor.relay.onionServices](options.html#opt-services.tor.relay.onionServices). A new [services.tor.openFirewall](options.html#opt-services.tor.openFirewall) option as been introduced for allowing connections on all the TCP ports configured. + +- The options `services.slurm.dbdserver.storagePass` and `services.slurm.dbdserver.configFile` have been removed. Use `services.slurm.dbdserver.storagePassFile` instead to provide the database password. Extra config options can be given via the option `services.slurm.dbdserver.extraConfig`. The actual configuration file is created on the fly on startup of the service. This avoids that the password gets exposed in the nix store. + +- The `wafHook` hook does not wrap Python anymore. Packages depending on `wafHook` need to include any Python into their `nativeBuildInputs`. + +- Starting with version 1.7.0, the project formerly named `CodiMD` is now named `HedgeDoc`. New installations will no longer use the old name for users, state directories and such, this needs to be considered when moving state to a more recent NixOS installation. Based on [system.stateVersion](options.html#opt-system.stateVersion), existing installations will continue to work. + +- The fish-foreign-env package has been replaced with fishPlugins.foreign-env, in which the fish functions have been relocated to the `vendor_functions.d` directory to be loaded automatically. + +- The prometheus json exporter is now managed by the prometheus community. Together with additional features some backwards incompatibilities were introduced. Most importantly the exporter no longer accepts a fixed command-line parameter to specify the URL of the endpoint serving JSON. It now expects this URL to be passed as an URL parameter, when scraping the exporter\'s `/probe` endpoint. In the prometheus scrape configuration the scrape target might look like this: + + ``` + http://some.json-exporter.host:7979/probe?target=https://example.com/some/json/endpoint + ``` + + Existing configuration for the exporter needs to be updated, but can partially be re-used. Documentation is available in the upstream repository and a small example for NixOS is available in the corresponding NixOS test. + + These changes also affect [services.prometheus.exporters.rspamd.enable](options.html#opt-services.prometheus.exporters.rspamd.enable), which is just a preconfigured instance of the json exporter. + + For more information, take a look at the [ official documentation](https://github.com/prometheus-community/json_exporter) of the json_exporter. + +- Androidenv was updated, removing the `includeDocs` and `lldbVersions` arguments. Docs only covered a single version of the Android SDK, LLDB is now bundled with the NDK, and both are no longer available to download from the Android package repositories. Additionally, since the package lists have been updated, some older versions of Android packages may not be bundled. If you depend on older versions of Android packages, we recommend overriding the repo. + + Android packages are now loaded from a repo.json file created by parsing Android repo XML files. The arguments `repoJson` and `repoXmls` have been added to allow overriding the built-in androidenv repo.json with your own. Additionally, license files are now written to allow compatibility with Gradle-based tools, and the `extraLicenses` argument has been added to accept more SDK licenses if your project requires it. See the androidenv documentation for more details. + +- The attribute `mpi` is now consistently used to provide a default, system-wide MPI implementation. The default implementation is openmpi, which has been used before by all derivations affects by this change. Note that all packages that have used `mpi ? null` in the input for optional MPI builds, have been changed to the boolean input paramater `useMpi` to enable building with MPI. Building all packages with `mpich` instead of the default `openmpi` can now be achived like this: + + ```nix + self: super: + { + mpi = super.mpich; + } + ``` + +- The Searx module has been updated with the ability to configure the service declaratively and uWSGI integration. The option `services.searx.configFile` has been renamed to [services.searx.settingsFile](options.html#opt-services.searx.settingsFile) for consistency with the new [services.searx.settings](options.html#opt-services.searx.settings). In addition, the `searx` uid and gid reservations have been removed since they were not necessary: the service is now running with a dynamically allocated uid. + +- The libinput module has been updated with the ability to configure mouse and touchpad settings separately. The options in `services.xserver.libinput` have been renamed to `services.xserver.libinput.touchpad`, while there is a new `services.xserver.libinput.mouse` for mouse related configuration. + + Since touchpad options no longer apply to all devices, you may want to replicate your touchpad configuration in mouse section. + +- ALSA OSS emulation (`sound.enableOSSEmulation`) is now disabled by default. + +- Thinkfan as been updated to `1.2.x`, which comes with a new YAML based configuration format. For this reason, several NixOS options of the thinkfan module have been changed to non-backward compatible types. In addition, a new [services.thinkfan.settings](options.html#opt-services.thinkfan.settings) option has been added. + + Please read the [ thinkfan documentation](https://github.com/vmatare/thinkfan#readme) before updating. + +- Adobe Flash Player support has been dropped from the tree. In particular, the following packages no longer support it: + + - chromium + + - firefox + + - qt48 + + - qt5.qtwebkit + + Additionally, packages flashplayer and hal-flash were removed along with the `services.flashpolicyd` module. + +- The `security.rngd` module has been removed. It was disabled by default in 20.09 as it was functionally redundant with krngd in the linux kernel. It is not necessary for any device that the kernel recognises as an hardware RNG, as it will automatically run the krngd task to periodically collect random data from the device and mix it into the kernel\'s RNG. + + The default SMTP port for GitLab has been changed to `25` from its previous default of `465`. If you depended on this default, you should now set the [services.gitlab.smtp.port](options.html#opt-services.gitlab.smtp.port) option. + +- The default version of ImageMagick has been updated from 6 to 7. You can use imagemagick6, imagemagick6_light, and imagemagick6Big if you need the older version. + +- [services.xserver.videoDrivers](options.html#opt-services.xserver.videoDrivers) no longer uses the deprecated `cirrus` and `vesa` device dependent X drivers by default. It also enables both `amdgpu` and `nouveau` drivers by default now. + +- The `kindlegen` package is gone, because it is no longer supported or hosted by Amazon. Sadly, its replacement, Kindle Previewer, has no Linux support. However, there are other ways to generate MOBI files. See [the discussion](https://github.com/NixOS/nixpkgs/issues/96439) for more info. + +- The apacheKafka packages are now built with version-matched JREs. Versions 2.6 and above, the ones that recommend it, use jdk11, while versions below remain on jdk8. The NixOS service has been adjusted to start the service using the same version as the package, adjustable with the new [services.apache-kafka.jre](options.html#opt-services.apache-kafka.jre) option. Furthermore, the default list of [services.apache-kafka.jvmOptions](options.html#opt-services.apache-kafka.jvmOptions) have been removed. You should set your own according to the [upstream documentation](https://kafka.apache.org/documentation/#java) for your Kafka version. + +- The kodi package has been modified to allow concise addon management. Consider the following configuration from previous releases of NixOS to install kodi, including the kodiPackages.inputstream-adaptive and kodiPackages.vfs-sftp addons: + + ```nix + { + environment.systemPackages = [ + pkgs.kodi + ]; + + nixpkgs.config.kodi = { + enableInputStreamAdaptive = true; + enableVFSSFTP = true; + }; + } + ``` + + All Kodi `config` flags have been removed, and as a result the above configuration should now be written as: + + ```nix + { + environment.systemPackages = [ + (pkgs.kodi.withPackages (p: with p; [ + inputstream-adaptive + vfs-sftp + ])) + ]; + } + ``` + +- `environment.defaultPackages` now includes the nano package. If pkgs.nano is not added to the list, make sure another editor is installed and the `EDITOR` environment variable is set to it. Environment variables can be set using `environment.variables`. + +- `services.minio.dataDir` changed type to a list of paths, required for specifiyng multiple data directories for using with erasure coding. Currently, the service doesn\'t enforce nor checks the correct number of paths to correspond to minio requirements. + +- All CUDA toolkit versions prior to CUDA 10 have been removed. + +- The kbdKeymaps package was removed since dvp and neo are now included in kbd. If you want to use the Programmer Dvorak Keyboard Layout, you have to use `dvorak-programmer` in `console.keyMap` now instead of `dvp`. In `services.xserver.xkbVariant` it\'s still `dvp`. + +- The babeld service is now being run as an unprivileged user. To achieve that the module configures `skip-kernel-setup true` and takes care of setting forwarding and rp_filter sysctls by itself as well as for each interface in `services.babeld.interfaces`. + +- The `services.zigbee2mqtt.config` option has been renamed to `services.zigbee2mqtt.settings` and now follows [RFC 0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md). + + The yadm dotfile manager has been updated from 2.x to 3.x, which has new (XDG) default locations for some data/state files. Most yadm commands will fail and print a legacy path warning (which describes how to upgrade/migrate your repository). If you have scripts, daemons, scheduled jobs, shell profiles, etc. that invoke yadm, expect them to fail or misbehave until you perform this migration and prepare accordingly. + +- Instead of determining `services.radicale.package` automatically based on `system.stateVersion`, the latest version is always used because old versions are not officially supported. + + Furthermore, Radicale\'s systemd unit was hardened which might break some deployments. In particular, a non-default `filesystem_folder` has to be added to `systemd.services.radicale.serviceConfig.ReadWritePaths` if the deprecated `services.radicale.config` is used. + +- In the `security.acme` module, use of `--reuse-key` parameter for Lego has been removed. It was introduced for HKPK, but this security feature is now deprecated. It is a better security practice to rotate key pairs instead of always keeping the same. If you need to keep this parameter, you can add it back using `extraLegoRenewFlags` as an option for the appropriate certificate. + +## Other Notable Changes {#sec-release-21.05-notable-changes} + +- `stdenv.lib` has been deprecated and will break eval in 21.11. Please use `pkgs.lib` instead. See [\#108938](https://github.com/NixOS/nixpkgs/issues/108938) for details. + +- [GNURadio](https://www.gnuradio.org/) has a `pkgs` attribute set, and there\'s a `gnuradio.callPackage` function that extends `pkgs` with a `mkDerivation`, and a `mkDerivationWith`, like Qt5. Now all `gnuradio.pkgs` are defined with `gnuradio.callPackage` and some packages that depend on gnuradio are defined with this as well. + +- [Privoxy](https://www.privoxy.org/) has been updated to version 3.0.32 (See [announcement](https://lists.privoxy.org/pipermail/privoxy-announce/2021-February/000007.html)). Compared to the previous release, Privoxy has gained support for HTTPS inspection (still experimental), Brotli decompression, several new filters and lots of bug fixes, including security ones. In addition, the package is now built with compression and external filters support, which were previously disabled. + + Regarding the NixOS module, new options for HTTPS inspection have been added and `services.privoxy.extraConfig` has been replaced by the new [services.privoxy.settings](options.html#opt-services.privoxy.settings) (See [RFC 0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md) for the motivation). + +- [Kodi](https://kodi.tv/) has been updated to version 19.1 \"Matrix\". See the [announcement](https://kodi.tv/article/kodi-19-0-matrix-release) for further details. + +- The `services.packagekit.backend` option has been removed as it only supported a single setting which would always be the default. Instead new [RFC 0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md) compliant [services.packagekit.settings](options.html#opt-services.packagekit.settings) and [services.packagekit.vendorSettings](options.html#opt-services.packagekit.vendorSettings) options have been introduced. + +- [Nginx](https://nginx.org) has been updated to stable version 1.20.0. Now nginx uses the zlib-ng library by default. + +- KDE Gear (formerly KDE Applications) is upgraded to 21.04, see its [release notes](https://kde.org/announcements/gear/21.04/) for details. + + The `kdeApplications` package set is now `kdeGear`, in keeping with the new name. The old name remains for compatibility, but it is deprecated. + +- [Libreswan](https://libreswan.org/) has been updated to version 4.4. The package now includes example configurations and manual pages by default. The NixOS module has been changed to use the upstream systemd units and write the configuration in the `/etc/ipsec.d/ ` directory. In addition, two new options have been added to specify connection policies ([services.libreswan.policies](options.html#opt-services.libreswan.policies)) and disable send/receive redirects ([services.libreswan.disableRedirects](options.html#opt-services.libreswan.disableRedirects)). + +- The Mailman NixOS module (`services.mailman`) has a new option [services.mailman.enablePostfix](options.html#opt-services.mailman.enablePostfix), defaulting to true, that controls integration with Postfix. + + If this option is disabled, default MTA config becomes not set and you should set the options in `services.mailman.settings.mta` according to the desired configuration as described in [Mailman documentation](https://mailman.readthedocs.io/en/latest/src/mailman/docs/mta.html). + +- The default-version of `nextcloud` is nextcloud21. Please note that it\'s _not_ possible to upgrade `nextcloud` across multiple major versions! This means that it\'s e.g. not possible to upgrade from nextcloud18 to nextcloud20 in a single deploy and most `20.09` users will have to upgrade to nextcloud20 first. + + The package can be manually upgraded by setting [services.nextcloud.package](options.html#opt-services.nextcloud.package) to nextcloud21. + +- The setting [services.redis.bind](options.html#opt-services.redis.bind) defaults to `127.0.0.1` now, making Redis listen on the loopback interface only, and not all public network interfaces. + +- NixOS now emits a deprecation warning if systemd\'s `StartLimitInterval` setting is used in a `serviceConfig` section instead of in a `unitConfig`; that setting is deprecated and now undocumented for the service section by systemd upstream, but still effective and somewhat buggy there, which can be confusing. See [\#45785](https://github.com/NixOS/nixpkgs/issues/45785) for details. + + All services should use [systemd.services._name_.startLimitIntervalSec](options.html#opt-systemd.services._name_.startLimitIntervalSec) or `StartLimitIntervalSec` in [systemd.services._name_.unitConfig](options.html#opt-systemd.services._name_.unitConfig) instead. + +- The `mediatomb` service declares new options. It also adapts existing options so the configuration generation is now lazy. The existing option `customCfg` (defaults to false), when enabled, stops the service configuration generation completely. It then expects the users to provide their own correct configuration at the right location (whereas the configuration was generated and not used at all before). The new option `transcodingOption` (defaults to no) allows a generated configuration. It makes the mediatomb service pulls the necessary runtime dependencies in the nix store (whereas it was generated with hardcoded values before). The new option `mediaDirectories` allows the users to declare autoscan media directories from their nixos configuration: + + ```nix + { + services.mediatomb.mediaDirectories = [ + { path = "/var/lib/mediatomb/pictures"; recursive = false; hidden-files = false; } + { path = "/var/lib/mediatomb/audio"; recursive = true; hidden-files = false; } + ]; + } + ``` + +- The Unbound DNS resolver service (`services.unbound`) has been refactored to allow reloading, control sockets and to fix startup ordering issues. + + It is now possible to enable a local UNIX control socket for unbound by setting the [services.unbound.localControlSocketPath](options.html#opt-services.unbound.localControlSocketPath) option. + + Previously we just applied a very minimal set of restrictions and trusted unbound to properly drop root privs and capabilities. + + As of this we are (for the most part) just using the upstream example unit file for unbound. The main difference is that we start unbound as `unbound` user with the required capabilities instead of letting unbound do the chroot & uid/gid changes. + + The upstream unit configuration this is based on is a lot stricter with all kinds of permissions then our previous variant. It also came with the default of having the `Type` set to `notify`, therefore we are now also using the `unbound-with-systemd` package here. Unbound will start up, read the configuration files and start listening on the configured ports before systemd will declare the unit `active (running)`. This will likely help with startup order and the occasional race condition during system activation where the DNS service is started but not yet ready to answer queries. Services depending on `nss-lookup.target` or `unbound.service` are now be able to use unbound when those targets have been reached. + + Additionally to the much stricter runtime environment the `/dev/urandom` mount lines we previously had in the code (that randomly failed during the stop-phase) have been removed as systemd will take care of those for us. + + The `preStart` script is now only required if we enabled the trust anchor updates (which are still enabled by default). + + Another benefit of the refactoring is that we can now issue reloads via either `pkill -HUP unbound` and `systemctl reload unbound` to reload the running configuration without taking the daemon offline. A prerequisite of this was that unbound configuration is available on a well known path on the file system. We are using the path `/etc/unbound/unbound.conf` as that is the default in the CLI tooling which in turn enables us to use `unbound-control` without passing a custom configuration location. + + The module has also been reworked to be [RFC 0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md) compliant. As such, `sevices.unbound.extraConfig` has been removed and replaced by [services.unbound.settings](options.html#opt-services.unbound.settings). `services.unbound.interfaces` has been renamed to `services.unbound.settings.server.interface`. + + `services.unbound.forwardAddresses` and `services.unbound.allowedAccess` have also been changed to use the new settings interface. You can follow the instructions when executing `nixos-rebuild` to upgrade your configuration to use the new interface. + +- The `services.dnscrypt-proxy2` module now takes the upstream\'s example configuration and updates it with the user\'s settings. An option has been added to restore the old behaviour if you prefer to declare the configuration from scratch. + +- NixOS now defaults to the unified cgroup hierarchy (cgroupsv2). See the [Fedora Article for 31](https://www.redhat.com/sysadmin/fedora-31-control-group-v2) for details on why this is desirable, and how it impacts containers. + + If you want to run containers with a runtime that does not yet support cgroupsv2, you can switch back to the old behaviour by setting [systemd.enableUnifiedCgroupHierarchy](options.html#opt-systemd.enableUnifiedCgroupHierarchy) = `false`; and rebooting. + +- PulseAudio was upgraded to 14.0, with changes to the handling of default sinks. See its [release notes](https://www.freedesktop.org/wiki/Software/PulseAudio/Notes/14.0/). + +- GNOME users may wish to delete their `~/.config/pulse` due to the changes to stream routing logic. See [PulseAudio bug 832](https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/832) for more information. + +- The zookeeper package does not provide `zooInspector.sh` anymore, as that \"contrib\" has been dropped from upstream releases. + +- In the ACME module, the data used to build the hash for the account directory has changed to accomodate new features to reduce account rate limit issues. This will trigger new account creation on the first rebuild following this update. No issues are expected to arise from this, thanks to the new account creation handling. + +- [users.users._name_.createHome](options.html#opt-users.users._name_.createHome) now always ensures home directory permissions to be `0700`. Permissions had previously been ignored for already existing home directories, possibly leaving them readable by others. The option\'s description was incorrect regarding ownership management and has been simplified greatly. + +- When defining a new user, one of [users.users._name_.isNormalUser](options.html#opt-users.users._name_.isNormalUser) and [users.users._name_.isSystemUser](options.html#opt-users.users._name_.isSystemUser) is now required. This is to prevent accidentally giving a UID above 1000 to system users, which could have unexpected consequences, like running user activation scripts for system users. Note that users defined with an explicit UID below 500 are exempted from this check, as [users.users._name_.isSystemUser](options.html#opt-users.users._name_.isSystemUser) has no effect for those. + +- The `security.apparmor` module, for the [AppArmor](https://gitlab.com/apparmor/apparmor/-/wikis/Documentation) Mandatory Access Control system, has been substantialy improved along with related tools, so that module maintainers can now more easily write AppArmor profiles for NixOS. The most notable change on the user-side is the new option [security.apparmor.policies](options.html#opt-security.apparmor.policies), replacing the previous `profiles` option to provide a way to disable a profile and to select whether to confine in enforce mode (default) or in complain mode (see `journalctl -b --grep apparmor`). Security-minded users may also want to enable [security.apparmor.killUnconfinedConfinables](options.html#opt-security.apparmor.killUnconfinedConfinables), at the cost of having some of their processes killed when updating to a NixOS version introducing new AppArmor profiles. + +- The GNOME desktop manager once again installs gnome.epiphany by default. + +- NixOS now generates empty `/etc/netgroup`. `/etc/netgroup` defines network-wide groups and may affect to setups using NIS. + +- Platforms, like `stdenv.hostPlatform`, no longer have a `platform` attribute. It has been (mostly) flattened away: + + - `platform.gcc` is now `gcc` + + - `platform.kernel*` is now `linux-kernel.*` + + Additionally, `platform.kernelArch` moved to the top level as `linuxArch` to match the other `*Arch` variables. + + The `platform` grouping of these things never meant anything, and was just a historial/implementation artifact that was overdue removal. + +- `services.restic` now uses a dedicated cache directory for every backup defined in `services.restic.backups`. The old global cache directory, `/root/.cache/restic`, is now unused and can be removed to free up disk space. + +- `isync`: The `isync` compatibility wrapper was removed and the Master/Slave terminology has been deprecated and should be replaced with Far/Near in the configuration file. + +- The nix-gc service now accepts randomizedDelaySec (default: 0) and persistent (default: true) parameters. By default nix-gc will now run immediately if it would have been triggered at least once during the time when the timer was inactive. + +- The `rustPlatform.buildRustPackage` function is split into several hooks: cargoSetupHook to set up vendoring for Cargo-based projects, cargoBuildHook to build a project using Cargo, cargoInstallHook to install a project using Cargo, and cargoCheckHook to run tests in Cargo-based projects. With this change, mixed-language projects can use the relevant hooks within builders other than `buildRustPackage`. However, these changes also required several API changes to `buildRustPackage` itself: + + - The `target` argument was removed. Instead, `buildRustPackage` will always use the same target as the C/C++ compiler that is used. + + - The `cargoParallelTestThreads` argument was removed. Parallel tests are now disabled through `dontUseCargoParallelTests`. + +- The `rustPlatform.maturinBuildHook` hook was added. This hook can be used with `buildPythonPackage` to build Python packages that are written in Rust and use Maturin as their build tool. + +- Kubernetes has [deprecated docker](https://kubernetes.io/blog/2020/12/02/dont-panic-kubernetes-and-docker/) as container runtime. As a consequence, the Kubernetes module now has support for configuration of custom remote container runtimes and enables containerd by default. Note that containerd is more strict regarding container image OCI-compliance. As an example, images with CMD or ENTRYPOINT defined as strings (not lists) will fail on containerd, while working fine on docker. Please test your setup and container images with containerd prior to upgrading. + +- The GitLab module now has support for automatic backups. A schedule can be set with the [services.gitlab.backup.startAt](options.html#opt-services.gitlab.backup.startAt) option. + +- Prior to this release, systemd would also read system units from an undocumented `/etc/systemd-mutable/system` path. This path has been dropped from the defaults. That path (or others) can be re-enabled by adding it to the [boot.extraSystemdUnitPaths](options.html#opt-boot.extraSystemdUnitPaths) list. + +- PostgreSQL 9.5 is scheduled EOL during the 21.05 life cycle and has been removed. + +- [Xfce4](https://www.xfce.org/) relies on GIO/GVfs for userspace virtual filesystem access in applications like [thunar](https://docs.xfce.org/xfce/thunar/) and [gigolo](https://docs.xfce.org/apps/gigolo/). For that to work, the gvfs nixos service is enabled by default, and it can be configured with the specific package that provides GVfs. Until now Xfce4 was setting it to use a lighter version of GVfs (without support for samba). To avoid conflicts with other desktop environments this setting has been dropped. Users that still want it should add the following to their system configuration: + + ```nix + { + services.gvfs.package = pkgs.gvfs.override { samba = null; }; + } + ``` + +- The newly enabled `systemd-pstore.service` now automatically evacuates crashdumps and panic logs from the persistent storage to `/var/lib/systemd/pstore`. This prevents NVRAM from filling up, which ensures the latest diagnostic data is always stored and alleviates problems with writing new boot configurations. + +- Nixpkgs now contains [automatically packaged GNOME Shell extensions](https://github.com/NixOS/nixpkgs/pull/118232) from the [GNOME Extensions](https://extensions.gnome.org/) portal. You can find them, filed by their UUID, under `gnome38Extensions` attribute for GNOME 3.38 and under `gnome40Extensions` for GNOME 40. Finally, the `gnomeExtensions` attribute contains extensions for the latest GNOME Shell version in Nixpkgs, listed under a more human-friendly name. The unqualified attribute scope also contains manually packaged extensions. Note that the automatically packaged extensions are provided for convenience and are not checked or guaranteed to work. + +- Erlang/OTP versions older than R21 got dropped. We also dropped the cuter package, as it was purely an example of how to build a package. We also dropped `lfe_1_2` as it could not build with R21+. Moving forward, we expect to only support 3 yearly releases of OTP. diff --git a/nixos/doc/manual/release-notes/rl-2111.section.md b/nixos/doc/manual/release-notes/rl-2111.section.md new file mode 100644 index 00000000000..310d32cfdd7 --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-2111.section.md @@ -0,0 +1,575 @@ +# Release 21.11 (“Porcupine”, 2021/11/30) {#sec-release-21.11} + +- Support is planned until the end of June 2022, handing over to 22.05. + +## Highlights {#sec-release-21.11-highlights} + +In addition to numerous new and upgraded packages, this release has the following highlights: + +- Nix has been updated to version 2.4, reference its [release notes](https://discourse.nixos.org/t/nix-2-4-released/15822) for more information on what has changed. The previous version of Nix, 2.3.16, remains available for the time being in the `nix_2_3` package. + +- `iptables` is now using `nf_tables` under the hood, by using `iptables-nft`, + similar to [Debian](https://wiki.debian.org/nftables#Current_status) and + [Fedora](https://fedoraproject.org/wiki/Changes/iptables-nft-default). + This means, `ip[6]tables`, `arptables` and `ebtables` commands will actually + show rules from some specific tables in the `nf_tables` kernel subsystem. + In case you're migrating from an older release without rebooting, there might + be cases where you end up with iptable rules configured both in the legacy + `iptables` kernel backend, as well as in the `nf_tables` backend. + This can lead to confusing firewall behaviour.

This breaking change was necessitated by a race condition causing tests to fail or hang. + It applies to all methods that invoke commands on the nodes, including `execute`, `succeed`, `fail`, `wait_until_succeeds`, `wait_until_fails`. + +- The `services.wakeonlan` option was removed, and replaced with `networking.interfaces.<name>.wakeOnLan`. + +- The `security.wrappers` option now requires to always specify an owner, group and whether the setuid/setgid bit should be set. + This is motivated by the fact that before NixOS 21.11, specifying either setuid or setgid but not owner/group resulted in wrappers owned by nobody/nogroup, which is unsafe. + +- Since `iptables` now uses `nf_tables` backend and `ipset` doesn't support it, some applications (ferm, shorewall, firehol) may have limited functionality. + +- The `paperless` module and package have been removed. All users should migrate to the + successor `paperless-ng` instead. The Paperless project [has been + archived](https://github.com/the-paperless-project/paperless/commit/9b0063c9731f7c5f65b1852cb8caff97f5e40ba4) + and advises all users to use `paperless-ng` instead. + + Users can use the `services.paperless-ng` module as a replacement while noting the following incompatibilities: + + - `services.paperless.ocrLanguages` has no replacement.

See [this Discourse post](https://community.tt-rss.org/t/rip-config-php-hello-classes-config-php/4337) in the tt-rss forums for more details. + +- The following Visual Studio Code extensions were renamed to keep the naming convention uniform. + + - `bbenoist.Nix` -> `bbenoist.nix` + - `CoenraadS.bracket-pair-colorizer` -> `coenraads.bracket-pair-colorizer` + - `golang.Go` -> `golang.go` + +- `services.uptimed` now uses `/var/lib/uptimed` as its stateDirectory instead of `/var/spool/uptimed`. Make sure to move all files to the new directory. + +- Deprecated package aliases in `emacs.pkgs.*` have been removed. These aliases were remnants of the old Emacs package infrastructure. We now use exact upstream names wherever possible. + +- `programs.neovim.runtime` switched to a `linkFarm` internally, making it impossible to use wildcards in the `source` argument. + +- The `openrazer` and `openrazer-daemon` packages as well as the `hardware.openrazer` module now require users to be members of the `openrazer` group instead of `plugdev`. With this change, users no longer need be granted the entire set of `plugdev` group permissions, which can include permissions other than those required by `openrazer`. This is desirable from a security point of view. The setting [`harware.openrazer.users`](options.html#opt-services.hardware.openrazer.users) can be used to add users to the `openrazer` group. + +- The fontconfig service's dpi option has been removed. + Fontconfig should use Xft settings by default so there's no need to override one value in multiple places. + The user can set DPI via ~/.Xresources properly, or at the system level per monitor, or as a last resort at the system level with `services.xserver.dpi`. + +- The `yambar` package has been split into `yambar` and `yambar-wayland`, corresponding to the xorg and wayland backend respectively. Please switch to `yambar-wayland` if you are on wayland. + +- The `services.minio` module gained an additional option `consoleAddress`, that + configures the address and port the web UI is listening, it defaults to `:9001`. + To be able to access the web UI this port needs to be opened in the firewall. + +- The `varnish` package was upgraded from 6.3.x to 7.x. `varnish60` for the last LTS release is also still available. + +- The `kubernetes` package was upgraded to 1.22. The `kubernetes.apiserver.kubeletHttps` option was removed and HTTPS is always used. + +- The attribute `linuxPackages_latest_hardened` was dropped because the hardened patches + lag behind the upstream kernel which made version bumps harder. If you want to use + a hardened kernel, please pin it explicitly with a versioned attribute such as + `linuxPackages_5_10_hardened`. + +- The `nomad` package now defaults to a 1.1.x release instead of 1.0.x + +- If `exfat` is included in `boot.supportedFilesystems` and when using kernel 5.7 + or later, the `exfatprogs` user-space utilities are used instead of `exfat`. + +- The `todoman` package was upgraded from 3.9.0 to 4.0.0. This introduces breaking changes in the [configuration file](https://todoman.readthedocs.io/en/stable/configure.html#configuration-file) format. + +- The `datadog-agent`, `datadog-integrations-core` and `datadog-process-agent` packages + were upgraded from 6.11.2 to 7.30.2, git-2018-09-18 to 7.30.1 and 6.11.1 to 7.30.2, + respectively. As a result `services.datadog-agent` has had breaking changes to the + configuration file. For details, see the [upstream changelog](https://github.com/DataDog/datadog-agent/blob/main/CHANGELOG.rst). + +- `opencv2` no longer includes the non-free libraries by default, and consequently `pfstools` no longer includes OpenCV support by default. Both packages now support an `enableUnfree` option to re-enable this functionality. +- `services.xserver.displayManager.defaultSession = "plasma5"` does not work anymore, instead use either `"plasma"` for the Plasma X11 session or `"plasmawayland"` for the Plasma Wayland sesison. + +- `boot.kernelParams` now only accepts one command line parameter per string. This change is aimed to reduce common mistakes like "param = 12", which would be parsed as 3 parameters. + +- `nix.daemonNiceLevel` and `nix.daemonIONiceLevel` have been removed in favour of the new options [`nix.daemonCPUSchedPolicy`](options.html#opt-nix.daemonCPUSchedPolicy), [`nix.daemonIOSchedClass`](options.html#opt-nix.daemonIOSchedClass) and [`nix.daemonIOSchedPriority`](options.html#opt-nix.daemonIOSchedPriority). Please refer to the options documentation and the `sched(7)` and `ioprio_set(2)` man pages for guidance on how to use them. + +- The `coursier` package's binary was renamed from `coursier` to `cs`. Completions which haven't worked for a while should now work with the renamed binary. To keep using `coursier`, you can create a shell alias. + +- The `services.mosquitto` module has been rewritten to support multiple listeners and per-listener configuration. + Module configurations from previous releases will no longer work and must be updated. + +- The `fluidsynth_1` attribute has been removed, as this legacy version is no longer needed in nixpkgs. The actively maintained 2.x series is available as `fluidsynth` unchanged. + +- Nextcloud 20 (`pkgs.nextcloud20`) has been dropped because it was EOLed by upstream in 2021-10. + +- The `virtualisation.pathsInNixDB` option was renamed + [`virtualisation.additionalPaths`](options.html#opt-virtualisation.additionalPaths). + +- The `services.ddclient.password` option was removed, and replaced with `services.ddclient.passwordFile`. + +- The default GNAT version has been changed: The `gnat` attribute now points to `gnat11` + instead of `gnat9`. + +- `retroArchCores` has been removed. This means that using `nixpkgs.config.retroarch` to customize RetroArch cores is not supported anymore. Instead, use package overrides, for example: `retroarch.override { cores = with libretro; [ citra snes9x ]; };`. Also, `retroarchFull` derivation is available for those who want to have all RetroArch cores available. + +- The Linux kernel for security reasons now restricts access to BPF syscalls via `BPF_UNPRIV_DEFAULT_OFF=y`. Unprivileged access can be reenabled via the `kernel.unprivileged_bpf_disabled` sysctl knob. + +- `/usr` will always be included in the initial ramdisk. See the `fileSystems.<name>.neededForBoot` option. + If any files exist under `/usr` (which is not typical for NixOS), they will be included in the initial ramdisk, increasing its size to a possibly problematic extent. + +## Other Notable Changes {#sec-release-21.11-notable-changes} + + +- The linux kernel package infrastructure was moved out of `all-packages.nix`, and restructured. Linux related functions and attributes now live under the `pkgs.linuxKernel` attribute set. + In particular the versioned `linuxPackages_*` package sets (such as `linuxPackages_5_4`) and kernels from `pkgs` were moved there and now live under `pkgs.linuxKernel.packages.*`. The unversioned ones (such as `linuxPackages_latest`) remain untouched. + +- In NixOS virtual machines (QEMU), the `virtualisation` module has been updated with new options: + - [`forwardPorts`](options.html#opt-virtualisation.forwardPorts) to configure IPv4 port forwarding, + - [`sharedDirectories`](options.html#opt-virtualisation.sharedDirectories) to set up shared host directories, + - [`resolution`](options.html#opt-virtualisation.resolution) to set the screen resolution, + - [`useNixStoreImage`](options.html#opt-virtualisation.useNixStoreImage) to use a disk image for the Nix store instead of 9P. + + In addition, the default [`msize`](options.html#opt-virtualisation.msize) parameter in 9P filesystems (including /nix/store and all shared directories) has been increased to 16K for improved performance. + +- The setting [`services.openssh.logLevel`](options.html#opt-services.openssh.logLevel) `"VERBOSE"` `"INFO"`. This brings NixOS in line with upstream and other Linux distributions, and reduces log spam on servers due to bruteforcing botnets. + + However, if [`services.fail2ban.enable`](options.html#opt-services.fail2ban.enable) is `true`, the `fail2ban` will override the verbosity to `"VERBOSE"`, so that `fail2ban` can observe the failed login attempts from the SSH logs. + +- The [`services.xserver.extraLayouts`](options.html#opt-services.xserver.extraLayouts) no longer cause additional rebuilds when a layout is added or modified. + +- Sway: The terminal emulator `rxvt-unicode` is no longer installed by default via `programs.sway.extraPackages`. The current default configuration uses `alacritty` (and soon `foot`) so this is only an issue when using a customized configuration and not installing `rxvt-unicode` explicitly. + +- `python3` now defaults to Python 3.9. Python 3.9 introduces many deprecation warnings, please look at the [What's New In Python 3.9 post](https://docs.python.org/3/whatsnew/3.9.html) for more information. + +- `qtile` hase been updated from '0.16.0' to '0.18.0', please check [qtile changelog](https://github.com/qtile/qtile/blob/master/CHANGELOG) for changes. + +- The `claws-mail` package now references the new GTK+ 3 release branch, major version 4. To use the GTK+ 2 releases, one can install the `claws-mail-gtk2` package. + +- The wordpress module provides a new interface which allows to use different webservers with the new option [`services.wordpress.webserver`](options.html#opt-services.wordpress.webserver). Currently `httpd`, `caddy` and `nginx` are supported. The definitions of wordpress sites should now be set in [`services.wordpress.sites`](options.html#opt-services.wordpress.sites). + + Sites definitions that use the old interface are automatically migrated in the new option. This backward compatibility will be removed in 22.05. + +- The dokuwiki module provides a new interface which allows to use different webservers with the new option [`services.dokuwiki.webserver`](options.html#opt-services.dokuwiki.webserver). Currently `caddy` and `nginx` are supported. The definitions of dokuwiki sites should now be set in [`services.dokuwiki.sites`](options.html#opt-services.dokuwiki.sites). + + Sites definitions that use the old interface are automatically migrated in the new option. This backward compatibility will be removed in 22.05. + +- The order of NSS (host) modules has been brought in line with upstream + recommendations: + + - The `myhostname` module is placed before the `resolve` (optional) and `dns` + entries, but after `file` (to allow overriding via `/etc/hosts` / + `networking.extraHosts`, and prevent ISPs with catchall-DNS resolvers from + hijacking `.localhost` domains) + - The `mymachines` module, which provides hostname resolution for local + containers (registered with `systemd-machined`) is placed to the front, to + make sure its mappings are preferred over other resolvers. + - If systemd-networkd is enabled, the `resolve` module is placed before + `files` and `myhostname`, as it provides the same logic internally, with + caching. + - The `mdns(_minimal)` module has been updated to the new priorities. + + If you use your own NSS host modules, make sure to update your priorities + according to these rules: + + - NSS modules which should be queried before `resolved` DNS resolution should + use mkBefore. + - NSS modules which should be queried after `resolved`, `files` and + `myhostname`, but before `dns` should use the default priority + - NSS modules which should come after `dns` should use mkAfter. + +- The [networking.wireless](options.html#opt-networking.wireless.enable) module (based on wpa_supplicant) has been heavily reworked, solving a number of issues and adding useful features: + - The automatic discovery of wireless interfaces at boot has been made reliable again (issues [#101963](https://github.com/NixOS/nixpkgs/issues/101963), [#23196](https://github.com/NixOS/nixpkgs/issues/23196)). + - WPA3 and Fast BSS Transition (802.11r) are now enabled by default for all networks. + - Secrets like pre-shared keys and passwords can now be handled safely, meaning without including them in a world-readable file (`wpa_supplicant.conf` under /nix/store). + This is achieved by storing the secrets in a secured [environmentFile](options.html#opt-networking.wireless.environmentFile) and referring to them though environment variables that are expanded inside the configuration. + - With multiple interfaces declared, independent wpa_supplicant daemons are started, one for each interface (the services are named `wpa_supplicant-wlan0`, `wpa_supplicant-wlan1`, etc.). + - The generated `wpa_supplicant.conf` file is now formatted for easier reading. + - A new [scanOnLowSignal](options.html#opt-networking.wireless.scanOnLowSignal) option has been added to facilitate fast roaming between access points (enabled by default). + - A new [networks.<name>.authProtocols](options.html#opt-networking.wireless.networks._name_.authProtocols) option has been added to change the authentication protocols used when connecting to a network. + +- The [networking.wireless.iwd](options.html#opt-networking.wireless.iwd.enable) module has a new [networking.wireless.iwd.settings](options.html#opt-networking.wireless.iwd.settings) option. + +- The [services.smokeping.host](options.html#opt-services.smokeping.host) option was added and defaulted to `localhost`. Before, `smokeping` listened to all interfaces by default. NixOS defaults generally aim to provide non-Internet-exposed defaults for databases and internal monitoring tools, see e.g. [#100192](https://github.com/NixOS/nixpkgs/issues/100192). Further, the systemd service for `smokeping` got reworked defaults for increased operational stability, see [PR #144127](https://github.com/NixOS/nixpkgs/pull/144127) for details. + +- The [services.syncoid.enable](options.html#opt-services.syncoid.enable) module now properly drops ZFS permissions after usage. Before it delegated permissions to whole pools instead of datasets and didn't clean up after execution. You can manually look this up for your pools by running `zfs allow your-pool-name` and use `zfs unallow syncoid your-pool-name` to clean this up. + +- Zfs: `latestCompatibleLinuxPackages` is now exported on the zfs package. One can use `boot.kernelPackages = config.boot.zfs.package.latestCompatibleLinuxPackages;` to always track the latest compatible kernel with a given version of zfs. + +- Nginx will use the value of `sslTrustedCertificate` if provided for a virtual host, even if `enableACME` is set. This is useful for providers not using the same certificate to sign OCSP responses and server certificates. + +- `lib.formats.yaml`'s `generate` will not generate JSON anymore, but instead use more of the YAML-specific syntax. + +- MariaDB was upgraded from 10.5.x to 10.6.x. Please read the [upstream release notes](https://mariadb.com/kb/en/changes-improvements-in-mariadb-106/) for changes and upgrade instructions. + +- The MariaDB C client library, also known as libmysqlclient or mariadb-connector-c, was upgraded from 3.1.x to 3.2.x. While this should hopefully not have any impact, this upgrade comes with some changes to default behavior, so you might want to review the [upstream release notes](https://mariadb.com/kb/en/changes-and-improvements-in-mariadb-connector-c-32/). + +- GNOME desktop environment now enables `QGnomePlatform` as the Qt platform theme, which should avoid crashes when opening file chooser dialogs in Qt apps by using XDG desktop portal. Additionally, it will make the apps fit better visually. + +- `rofi` has been updated from '1.6.1' to '1.7.0', one important thing is the removal of the old xresources based configuration setup. Read more [in rofi's changelog](https://github.com/davatorium/rofi/blob/cb12e6fc058f4a0f4f/Changelog#L1). + +- ipfs now defaults to not listening on you local network. This setting was change as server providers won't accept port scanning on their private network. If you have several ipfs instances running on a network you own, feel free to change the setting `ipfs.localDiscovery = true;`. localDiscovery enables different instances to discover each other and share data. + +- `lua` and `luajit` interpreters have been patched to avoid looking into /usr/lib + directories, thus increasing the purity of the build. + +- Three new options, [xdg.mime.addedAssociations](#opt-xdg.mime.addedAssociations), [xdg.mime.defaultApplications](#opt-xdg.mime.defaultApplications), and [xdg.mime.removedAssociations](#opt-xdg.mime.removedAssociations) have been added to the [xdg.mime](#opt-xdg.mime.enable) module to allow the configuration of `/etc/xdg/mimeapps.list`. + +- Kopia was upgraded from 0.8.x to 0.9.x. Please read the [upstream release notes](https://github.com/kopia/kopia/releases/tag/v0.9.0) for changes and upgrade instructions. + +- The `systemd.network` module has gained support for the FooOverUDP link type. + +- The `networking` module has a new `networking.fooOverUDP` option to configure Foo-over-UDP encapsulations. + +- `networking.sits` now supports Foo-over-UDP encapsulation. + +- The `virtualisation.libvirtd` module has been refactored and updated with new options: + - `virtualisation.libvirtd.qemu*` options (e.g.: `virtualisation.libvirtd.qemuRunAsRoot`) were moved to [`virtualisation.libvirtd.qemu`](options.html#opt-virtualisation.libvirtd.qemu) submodule, + - software TPM1/TPM2 support (e.g.: Windows 11 guests) ([`virtualisation.libvirtd.qemu.swtpm`](options.html#opt-virtualisation.libvirtd.qemu.swtpm)), + - custom OVMF package (e.g.: `pkgs.OVMFFull` with HTTP, CSM and Secure Boot support) ([`virtualisation.libvirtd.qemu.ovmf.package`](options.html#opt-virtualisation.libvirtd.qemu.ovmf.package)). + +- The `cawbird` Twitter client now uses its own API keys to count as different application than upstream builds. This is done to evade application-level rate limiting. While existing accounts continue to work, users may want to remove and re-register their account in the client to enjoy a better user experience and benefit from this change. + +- A new option `services.prometheus.enableReload` has been added which can be enabled to reload the prometheus service when its config file changes instead of restarting. + +- The option `services.prometheus.environmentFile` has been removed since it was causing [issues](https://github.com/NixOS/nixpkgs/issues/126083) and Prometheus now has native support for secret files, i.e. `basic_auth.password_file` and `authorization.credentials_file`. + +- Dokuwiki now supports caddy! However + - the nginx option has been removed, in the new configuration, please use the `dokuwiki.webserver = "nginx"` instead. + - The "${hostname}" option has been deprecated, please use `dokuwiki.sites = [ "${hostname}" ]` instead + +- The [services.unifi](options.html#opt-services.unifi.enable) module has been reworked, solving a number of issues. This leads to several user facing changes: + - The `services.unifi.dataDir` option is removed and the data is now always located under `/var/lib/unifi/data`. This is done to make better use of systemd state direcotiry and thus making the service restart more reliable. + - The unifi logs can now be found under: `/var/log/unifi` instead of `/var/lib/unifi/logs`. + - The unifi run directory can now be found under: `/run/unifi` instead of `/var/lib/unifi/run`. + +- `security.pam.services.<name>.makeHomeDir` now uses `umask=0077` instead of `umask=0022` when creating the home directory. + +- Loki has had another release. Some default values have been changed for the configuration and some configuration options have been renamed. For more details, please check [the upgrade guide](https://grafana.com/docs/loki/latest/upgrading/#240). + +- `julia` now refers to `julia-stable` instead of `julia-lts`. In practice this means it has been upgraded from `1.0.4` to `1.5.4`. + +- RetroArch has been upgraded from version `1.8.5` to `1.9.13.2`. Since the previous release was quite old, if you're having issues after the upgrade, please delete your `$XDG_CONFIG_HOME/retroarch/retroarch.cfg` file. + +- hydrus has been upgraded from version `438` to `463`. Since upgrading between releases this old is advised against, be sure to have a backup of your data before upgrading. For details, see [the hydrus manual](https://hydrusnetwork.github.io/hydrus/help/getting_started_installing.html#big_updates). + +- More jdk and jre versions are now exposed via `java-packages.compiler`. diff --git a/nixos/doc/manual/release-notes/rl-2205.section.md b/nixos/doc/manual/release-notes/rl-2205.section.md new file mode 100644 index 00000000000..37ff778dd9b --- /dev/null +++ b/nixos/doc/manual/release-notes/rl-2205.section.md @@ -0,0 +1,582 @@ +# Release 22.05 (“Quokka”, 2022.05/??) {#sec-release-22.05} + +In addition to numerous new and upgraded packages, this release has the following highlights: + +- Support is planned until the end of December 2022, handing over to 22.11. + +## Highlights {#sec-release-22.05-highlights} + +- `security.acme.defaults` has been added to simplify configuring + settings for many certificates at once.

Additionally, the `withLLVM` parameter has been renamed to + `useLLVM`. So instead of `(ghc.withPackages (p: [])).override { withLLVM = true; }`, + one needs to use `(ghc.withPackages.override { useLLVM = true; }) (p: [])`. + +- The `home-assistant` module now requires users that don't want their + configuration to be managed declaratively to set + `services.home-assistant.config = null;`. This is required + due to the way default settings are handled with the new settings style. + + Additionally the default list of `extraComponents` now includes the minimal + dependencies to successfully complete the [onboarding](https://www.home-assistant.io/getting-started/onboarding/) + procedure. + +- `pkgs.emacsPackages.orgPackages` is removed because org elpa is deprecated. + The packages in the top level of `pkgs.emacsPackages`, such as org and + org-contrib, refer to the ones in `pkgs.emacsPackages.elpaPackages` and + `pkgs.emacsPackages.nongnuPackages` where the new versions will release. + +- `services.kubernetes.addons.dashboard` was removed due to it being an outdated version. + +- `services.kubernetes.scheduler.{port,address}` now set `--secure-port` and `--bind-address` instead of `--port` and `--address`, since the former have been deprecated and are no longer functional in kubernetes>=1.23. Ensure that you are not relying on the insecure behaviour before upgrading. + +- `services.k3s.enable` no longer implies `systemd.enableUnifiedCgroupHierarchy = false`, and will default to the 'systemd' cgroup driver when using `services.k3s.docker = true`. + This change may require a reboot to take effect, and k3s may not be able to run if the boot cgroup hierarchy does not match its configuration. + The previous behavior may be retained by explicitly setting `systemd.enableUnifiedCgroupHierarchy = false` in your configuration. + +- `fonts.fonts` no longer includes ancient bitmap fonts when both `config.services.xserver.enable` and `config.nixpkgs.config.allowUnfree` are enabled. + If you still want these fonts, use: + + ```nix + { + fonts.fonts = [ + pkgs.xorg.fontbhlucidatypewriter100dpi + pkgs.xorg.fontbhlucidatypewriter75dpi + pkgs.xorg.fontbh100dpi + ]; + } + ``` + +- The DHCP server (`services.dhcpd4`, `services.dhcpd6`) has been hardened. + The service is now using the systemd's `DynamicUser` mechanism to run as an unprivileged dynamically-allocated user with limited capabilities. + The dhcpd state files are now always stored in `/var/lib/dhcpd{4,6}` and the `services.dhcpd4.stateDir` and `service.dhcpd6.stateDir` options have been removed. + If you were depending on root privileges or set{uid,gid,cap} binaries in dhcpd shell hooks, you may give dhcpd more capabilities with e.g. `systemd.services.dhcpd6.serviceConfig.AmbientCapabilities`. + +- The `mailpile` email webclient (`services.mailpile`) has been removed due to its reliance on python2. + +- The `matrix-synapse` service (`services.matrix-synapse`) has been converted to use the `settings` option defined in RFC42. + This means that options that are part of your `homeserver.yaml` configuration, and that were specified at the top-level of the + module (`services.matrix-synapse`) now need to be moved into `services.matrix-synapse.settings`. And while not all options you + may use are defined in there, they are still supported, because you can set arbitrary values in this freeform type. + + The `listeners.*.bind_address` option was renamed to `bind_addresses` in order to match the upstream `homeserver.yaml` option + name. It is now also a list of strings instead of a string. + + An example to make the required migration clearer: + + Before: + ```nix + { + services.matrix-synapse = { + enable = true; + + server_name = "example.com"; + public_baseurl = "https://example.com:8448"; + + enable_registration = false; + registration_shared_secret = "xohshaeyui8jic7uutuDogahkee3aehuaf6ei3Xouz4iicie5thie6nohNahceut"; + macaroon_secret_key = "xoo8eder9seivukaiPh1cheikohquuw8Yooreid0The4aifahth3Ou0aiShaiz4l"; + + tls_certificate_path = "/var/lib/acme/example.com/fullchain.pem"; + tls_certificate_path = "/var/lib/acme/example.com/fullchain.pem"; + + listeners = [ { + port = 8448; + bind_address = ""; + type = "http"; + tls = true; + resources = [ { + names = [ "client" ]; + compress = true; + } { + names = [ "federation" ]; + compress = false; + } ]; + } ]; + + }; + } + ``` + + After: + ```nix + { + services.matrix-synapse = { + enable = true; + + # this attribute set holds all values that go into your homeserver.yaml configuration + # See https://github.com/matrix-org/synapse/blob/develop/docs/sample_config.yaml for + # possible values. + settings = { + server_name = "example.com"; + public_baseurl = "https://example.com:8448"; + + enable_registration = false; + # pass `registration_shared_secret` and `macaroon_secret_key` via `extraConfigFiles` instead + + tls_certificate_path = "/var/lib/acme/example.com/fullchain.pem"; + tls_certificate_path = "/var/lib/acme/example.com/fullchain.pem"; + + listeners = [ { + port = 8448; + bind_addresses = [ + "::" + "0.0.0.0" + ]; + type = "http"; + tls = true; + resources = [ { + names = [ "client" ]; + compress = true; + } { + names = [ "federation" ]; + compress = false; + } ]; + } ]; + }; + + extraConfigFiles = [ + /run/keys/matrix-synapse/secrets.yaml + ]; + }; + } + ``` + + The secrets in your original config should be migrated into a YAML file that is included via `extraConfigFiles`. + + Additionally a few option defaults have been synced up with upstream default values, for example the `max_upload_size` grew from `10M` to `50M`. For the same reason, the default + `media_store_path` was changed from `${dataDir}/media` to `${dataDir}/media_store` if `system.stateVersion` is at least `22.05`. Files will need to be manually moved to the new + location if the `stateVersion` is updated. + +- The MoinMoin wiki engine (`services.moinmoin`) has been removed, because Python 2 is being retired from nixpkgs. + +- Services in the `hadoop` module previously set `openFirewall` to true by default. + This has now been changed to false. Node definitions for multi-node clusters would need + `openFirewall = true;` to be added to to hadoop services when upgrading from NixOS 21.11. + +- `services.hadoop.yarn.nodemanager` now uses cgroup-based CPU limit enforcement by default. + Additionally, the option `useCGroups` was added to nodemanagers as an easy way to switch + back to the old behavior. + +- The `wafHook` hook now honors `NIX_BUILD_CORES` when `enableParallelBuilding` is not set explicitly. Packages can restore the old behaviour by setting `enableParallelBuilding=false`. + +- `pkgs.claws-mail-gtk2`, representing Claws Mail's older release version three, was removed in order to get rid of Python 2. + Please switch to `claws-mail`, which is Claws Mail's latest release based on GTK+3 and Python 3. + +- The `writers.writePython2` and corresponding `writers.writePython2Bin` convenience functions to create executable Python 2 scripts in the store were removed in preparation of removal of the Python 2 interpreter. + Scripts have to be converted to Python 3 for use with `writers.writePython3` or `writers.writePyPy2` needs to be used. + +- `buildGoModule` was updated to use `go_1_17`, third party derivations that specify >= go 1.17 in the main `go.mod` will need to regenerate their `vendorSha256` hash. + +- The `gnome-passwordsafe` package updated to [version 6.x](https://gitlab.gnome.org/World/secrets/-/tags/6.0) and renamed to `gnome-secrets`. + +- If you previously used `/etc/docker/daemon.json`, you need to incorporate the changes into the new option `virtualisation.docker.daemon.settings`. + +- Ntopng (`services.ntopng`) is updated to 5.2.1 and uses a separate Redis instance if `system.stateVersion` is at least `22.05`. Existing setups shouldn't be affected. + +- The backward compatibility in `services.wordpress` to configure sites with + the old interface has been removed. Please use `services.wordpress.sites` + instead. + +- The backward compatibility in `services.dokuwiki` to configure sites with the + old interface has been removed. Please use `services.dokuwiki.sites` instead. + +- opensmtpd-extras is no longer build with python2 scripting support due to python2 deprecation in nixpkgs + +- `services.miniflux.adminCredentialFiles` is now required, instead of defaulting to `admin` and `password`. + +- The `autorestic` package has been upgraded from 1.3.0 to 1.5.0 which introduces breaking changes in config file, check [their migration guide](https://autorestic.vercel.app/migration/1.4_1.5) for more details. + +- For `pkgs.python3.pkgs.ipython`, its direct dependency `pkgs.python3.pkgs.matplotlib-inline` + (which is really an adapter to integrate matplotlib in ipython if it is installed) does + not depend on `pkgs.python3.pkgs.matplotlib` anymore. + This is closer to a non-Nix install of ipython. + This has the added benefit to reduce the closure size of `ipython` from ~400MB to ~160MB + (including ~100MB for python itself). + +- `documentation.man` has been refactored to support choosing a man implementation other than GNU's `man-db`. For this, `documentation.man.manualPages` has been renamed to `documentation.man.man-db.manualPages`. If you want to use the new alternative man implementation `mandoc`, add `documentation.man = { enable = true; man-db.enable = false; mandoc.enable = true; }` to your configuration. + +- Normal users (with `isNormalUser = true`) which have non-empty `subUidRanges` or `subGidRanges` set no longer have additional implicit ranges allocated. To enable automatic allocation back set `autoSubUidGidRange = true`. + +- `idris2` now requires `--package` when using packages `contrib` and `network`, while previously these idris2 packages were automatically loaded. + +- The iputils package, which is installed by default, no longer provides the + legacy tools `tftpd` and `traceroute6`. More tools (`ninfod`, `rarpd`, and + `rdisc`) are going to be removed in the next release. See + [upstream's release notes](https://github.com/iputils/iputils/releases/tag/20211215) + for more details and available replacements. + +- `services.thelounge.private` was removed in favor of `services.thelounge.public`, to follow with upstream changes. + +- `pkgs.docbookrx` was removed since it's unmaintained + +- `pkgs._7zz` is now correctly licensed as LGPL3+ and BSD3 with optional unfree unRAR licensed code + +- `tilp2` was removed together with its module + +- The F-PROT antivirus (`fprot` package) and its service module were removed because it + reached [end-of-life](https://kb.cyren.com/av-support/index.php?/Knowledgebase/Article/View/434/0/end-of-sale--end-of-life-for-f-prot-and-csam). + +- `bird1` and its modules `services.bird` as well as `services.bird6` have been removed. Upgrade to `services.bird2`. + +- The options `networking.interfaces.<name>.ipv4.routes` and `networking.interfaces.<name>.ipv6.routes` are no longer ignored when using networkd instead of the default scripted network backend by setting `networking.useNetworkd` to `true`. + +- MultiMC has been replaced with the fork PolyMC due to upstream developers being hostile to 3rd party package maintainers. PolyMC removes all MultiMC branding and is aimed at providing proper 3rd party packages like the one contained in Nixpkgs. This change affects the data folder where game instances and other save and configuration files are stored. Users with existing installations should rename `~/.local/share/multimc` to `~/.local/share/polymc`. The main config file's path has also moved from `~/.local/share/multimc/multimc.cfg` to `~/.local/share/polymc/polymc.cfg`. + +- `systemd-nspawn@.service` settings have been reverted to the default systemd behaviour. User namespaces are now activated by default. If you want to keep running nspawn containers without user namespaces you need to set `systemd.nspawn.<name>.execConfig.PrivateUsers = false` + +- The Tor SOCKS proxy is now actually disabled if `services.tor.client.enable` is set to `false` (the default). If you are using this functionality but didn't change the setting or set it to `false`, you now need to set it to `true`. + +- The terraform 0.12 compatibility has been removed and the `terraform.withPlugins` and `terraform-providers.mkProvider` implementations simplified. Providers now need to be stored under +`$out/libexec/terraform-providers/<registry>/<owner>/<name>/<version>/<os>_<arch>/terraform-provider-<name>_v<version>` (which mkProvider does). + + This breaks back-compat so it's not possible to mix-and-match with previous versions of nixpkgs. In exchange, it now becomes possible to use the providers from [nixpkgs-terraform-providers-bin](https://github.com/numtide/nixpkgs-terraform-providers-bin) directly. + +- The `dendrite` package has been upgraded from 0.5.1 to + [0.6.5](https://github.com/matrix-org/dendrite/releases/tag/v0.6.5). Instances + configured with split sqlite databases, which has been the default + in NixOS, require merging of the federation sender and signing key + databases. See upstream [release + notes](https://github.com/matrix-org/dendrite/releases/tag/v0.6.0) + on version 0.6.0 for details on database changes. + +- The existing `pkgs.opentelemetry-collector` has been moved to + `pkgs.opentelemetry-collector-contrib` to match the actual source being the + "contrib" edition. `pkgs.opentelemetry-collector` is now the actual core + release of opentelemetry-collector. If you use the community contributions + you should change the package you refer to. If you don't need them update your + commands from `otelcontribcol` to `otelcorecol` and enjoy a 7x smaller binary. + +- `pkgs.pgadmin` now refers to `pkgs.pgadmin4`. + If you still need pgadmin3, use `pkgs.pgadmin3`. + +- `pkgs.noto-fonts-cjk` is now deprecated in favor of `pkgs.noto-fonts-cjk-sans` + and `pkgs.noto-fonts-cjk-serif` because they each have different release + schedules. To maintain compatibility with prior releases of Nixpkgs, + `pkgs.noto-fonts-cjk` is currently an alias of `pkgs.noto-fonts-cjk-sans` and + doesn't include serif fonts. + +- `pkgs.epgstation` has been upgraded from v1 to v2, resulting in incompatible + changes in the database scheme and configuration format. + +- Some top-level settings under [services.epgstation](#opt-services.epgstation.enable) + is now deprecated because it was redudant due to the same options being + present in [services.epgstation.settings](#opt-services.epgstation.settings). + +- The option `services.epgstation.basicAuth` was removed because basic + authentication support was dropped by upstream. + +- The option [services.epgstation.database.passwordFile](#opt-services.epgstation.database.passwordFile) + no longer has a default value. Make sure to set this option explicitly before + upgrading. Change the database password if necessary. + +- The [services.epgstation.settings](#opt-services.epgstation.settings) + option now expects options for `config.yml` in EPGStation v2. + +- Existing data for the [services.epgstation](#opt-services.epgstation.enable) + module would have to be backed up prior to the upgrade. To back up exising + data to `/tmp/epgstation.bak`, run + `sudo -u epgstation epgstation run backup /tmp/epgstation.bak`. + To import that data after to the upgrade, run + `sudo -u epgstation epgstation run v1migrate /tmp/epgstation.bak` + +- `switch-to-configuration` (the script that is run when running `nixos-rebuild switch` for example) has been reworked + * The interface that allows activation scripts to restart units has been streamlined. Restarting and reloading is now done by a single file `/run/nixos/activation-restart-list` that honors `restartIfChanged` and `reloadIfChanged` of the units. + * Preferring to reload instead of restarting can still be achieved using `/run/nixos/activation-reload-list`. + * The script now uses a proper ini-file parser to parse systemd units. Some values are now only searched in one section instead of in the entire unit. This is only relevant for units that don't use the NixOS systemd moule. + * `RefuseManualStop`, `X-OnlyManualStart`, `X-StopOnRemoval`, `X-StopOnReconfiguration` are only searched in the `[Unit]` section + * `X-ReloadIfChanged`, `X-RestartIfChanged`, `X-StopIfChanged` are only searched in the `[Service]` section + +- The `services.bookstack.cacheDir` option has been removed, since the + cache directory is now handled by systemd. + +- The `services.bookstack.extraConfig` option has been replaced by + `services.bookstack.config` which implements a + [settings-style](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md) + configuration. + +- `lib.assertMsg` and `lib.assertOneOf` no longer return `false` if the passed condition is `false`, `throw`ing the given error message instead (which makes the resulting error message less cluttered). This will not impact the behaviour of code using these functions as intended, namely as top-level wrapper for `assert` conditions. + +- The `vpnc` package has been changed to use GnuTLS instead of OpenSSL by default for licensing reasons. + +- `pkgs.vimPlugins.onedark-nvim` now refers to [navarasu/onedark.nvim](https://github.com/navarasu/onedark.nvim) + (formerly refers to [olimorris/onedarkpro.nvim](https://github.com/olimorris/onedarkpro.nvim)). + +- `services.pipewire.enable` will default to enabling the WirePlumber session manager instead of pipewire-media-session. + pipewire-media-session is deprecated by upstream and not recommended, but can still be manually enabled by setting + `services.pipewire.media-session.enable` to `true` and `services.pipewire.wireplumber.enable` to `false`. + +- `pkgs.makeDesktopItem` has been refactored to provide a more idiomatic API. Specifically: + - All valid options as of FDO Desktop Entry specification version 1.4 can now be passed in as explicit arguments + - `exec` can now be null, for entries that are not of type Application + - `mimeType` argument is renamed to `mimeTypes` for consistency + - `mimeTypes`, `categories`, `implements`, `keywords`, `onlyShowIn` and `notShowIn` take lists of strings instead of one string with semicolon separators + - `extraDesktopEntries` renamed to `extraConfig` for consistency + - Actions should now be provided as an attrset `actions`, the `Actions` line will be autogenerated. + - `extraEntries` is removed. + - Additional validation is added both at eval time and at build time. + + See the `vscode` package for a more detailed example. + +<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. --> + +## Other Notable Changes {#sec-release-22.05-notable-changes} + +- The option [services.redis.servers](#opt-services.redis.servers) was added + to support per-application `redis-server` which is more secure since Redis databases + are only mere key prefixes without any configuration or ACL of their own. + Backward-compatibility is preserved by mapping old `services.redis.settings` + to `services.redis.servers."".settings`, but you are strongly encouraged + to name each `redis-server` instance after the application using it, + instead of keeping that nameless one. + Except for the nameless `services.redis.servers.""` + still accessible at `127.0.0.1:6379`, + and to the members of the Unix group `redis` + through the Unix socket `/run/redis/redis.sock`, + all other `services.redis.servers.${serverName}` + are only accessible by default + to the members of the Unix group `redis-${serverName}` + through the Unix socket `/run/redis-${serverName}/redis.sock`. + +- The option [virtualisation.vmVariant](#opt-virtualisation.vmVariant) was added + to allow users to make changes to the `nixos-rebuild build-vm` configuration + that do not apply to their normal system. + + The `config.system.build.vm` attribute now always exists and defaults to the + value from `vmVariant`. Configurations that import the `virtualisation/qemu-vm.nix` + module themselves will override this value, such that `vmVariant` is not used. + + Similarly [virtualisation.vmVariantWithBootloader](#opt-virtualisation.vmVariantWithBootLoader) was added. + +- The configuration portion of the `nix-daemon` module has been reworked and exposed as [nix.settings](options.html#opt-nix-settings): + * Legacy options have been mapped to the corresponding options under under [nix.settings](options.html#opt-nix.settings) but may be deprecated in the future. + * [nix.buildMachines.publicHostKey](options.html#opt-nix.buildMachines.publicHostKey) has been added. + +- The `writers.writePyPy2`/`writers.writePyPy3` and corresponding `writers.writePyPy2Bin`/`writers.writePyPy3Bin` convenience functions to create executable Python 2/3 scripts using the PyPy interpreter were added. + +- Some improvements have been made to the `hadoop` module: + - A `gatewayRole` option has been added, for deploying hadoop cluster configuration files to a node that does not have any active services + - Support for older versions of hadoop have been added to the module + - Overriding and extending site XML files has been made easier + +- If you are using Wayland you can choose to use the Ozone Wayland support + in Chrome and several Electron apps by setting the environment variable + `NIXOS_OZONE_WL=1` (for example via + `environment.sessionVariables.NIXOS_OZONE_WL = "1"`). + This is not enabled by default because Ozone Wayland is + still under heavy development and behavior is not always flawless. + Furthermore, not all Electron apps use the latest Electron versions. + +- The `influxdb2` package was split into `influxdb2-server` and + `influxdb2-cli`, matching the split that took place upstream. A + combined `influxdb2` package is still provided in this release for + backwards compatibilty, but will be removed at a later date. + +- The `unifi` package was switched from `unifi6` to `unifi7`. + Direct downgrades from Unifi 7 to Unifi 6 are not possible and require restoring from a backup made by Unifi 6. + +- `programs.zsh.autosuggestions.strategy` now takes a list of strings instead of a string. + +- The `services.unifi.openPorts` option default value of `true` is now deprecated and will be changed to `false` in 22.11. + Configurations using this default will print a warning when rebuilt. + +- `security.acme` certificates will now correctly check for CA + revokation before reaching their minimum age. + +- Removing domains from `security.acme.certs._name_.extraDomainNames` + will now correctly remove those domains during rebuild/renew. + +- MariaDB is now offered in several versions, not just the newest one. + So if you have a need for running MariaDB 10.4 for example, you can now just set `services.mysql.package = pkgs.mariadb_104;`. + In general, it is recommended to run the newest version, to get the newest features, while sticking with an LTS version will most likely provide a more stable experience. + Sometimes software is also incompatible with the newest version of MariaDB. + +- The option + [programs.ssh.enableAskPassword](#opt-programs.ssh.enableAskPassword) was + added, decoupling the setting of `SSH_ASKPASS` from + `services.xserver.enable`. This allows easy usage in non-X11 environments, + e.g. Wayland. + +- [programs.ssh.knownHosts](#opt-programs.ssh.knownHosts) has gained an `extraHostNames` + option to replace `hostNames`. `hostNames` is deprecated, but still available for now. + +- The `services.stubby` module was converted to a [settings-style](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md) configuration. + +- The option `services.duplicati.dataDir` has been added to allow changing the location of duplicati's files. + +- The options `boot.extraModprobeConfig` and `boot.blacklistedKernelModules` now also take effect in the initrd by copying the file `/etc/modprobe.d/nixos.conf` into the initrd. + +- `nixos-generate-config` now puts the dhcp configuration in `hardware-configuration.nix` instead of `configuration.nix`. + +- ORY Kratos was updated to version 0.8.3-alpha.1.pre.0, which introduces some breaking changes: + - If you are relying on the SQLite images, update your Docker Pull commands as follows: + - `docker pull oryd/kratos:{version}` + - Additionally, all passwords now have to be at least 8 characters long. + - For more details, see: + - [Release Notes for v0.8.1-alpha-1](https://github.com/ory/kratos/releases/tag/v0.8.1-alpha.1) + - [Release Notes for v0.8.2-alpha-1](https://github.com/ory/kratos/releases/tag/v0.8.2-alpha.1) + +- `fetchFromSourcehut` now allows fetching repositories recursively + using `fetchgit` or `fetchhg` if the argument `fetchSubmodules` + is set to `true`. + +- The `element-desktop` package now has an `useKeytar` option (defaults to `true`), + which allows disabling `keytar` and in turn `libsecret` usage + (which binds to native credential managers / keychain libraries). + +- The option `services.thelounge.plugins` has been added to allow installing plugins for The Lounge. Plugins can be found in `pkgs.theLoungePlugins.plugins` and `pkgs.theLoungePlugins.themes`. + +- The option `services.xserver.videoDriver = [ "nvidia" ];` will now also install [nvidia VA-API drivers](https://github.com/elFarto/nvidia-vaapi-driver) by default. + +- The `firmwareLinuxNonfree` package has been renamed to `linux-firmware`. + +- It is now possible to specify wordlists to include as handy to access environment variables using the `config.environment.wordlist` configuration options. + +- The `services.mbpfan` module was converted to a [RFC 0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md) configuration. + +- The default value for `programs.spacefm.settings.graphical_su` got unset. It previously pointed to `gksu` which has been removed. + +- A new module was added for the [Starship](https://starship.rs/) shell prompt, + providing the options `programs.starship.enable` and `programs.starship.settings`. + +- The [Dino](https://dino.im) XMPP client was updated to 0.3, adding support for audio and video calls. + +- `services.mattermost.plugins` has been added to allow the declarative installation of Mattermost plugins. + Plugins are automatically repackaged using autoPatchelf. + +- `services.logrotate.enable` now defaults to true if any rotate path has + been defined, and some paths have been added by default. + +- The `zrepl` package has been updated from 0.4.0 to 0.5: + + - The RPC protocol version was bumped; all zrepl daemons in a setup must be updated and restarted before replication can resume. + - A bug involving encrypt-on-receive has been fixed. Read the [zrepl documentation](https://zrepl.github.io/configuration/sendrecvoptions.html#job-recv-options-placeholder) and check the output of `zfs get -r encryption,zrepl:placeholder PATH_TO_ROOTFS` on the receiver. + +- Renamed option `services.openssh.challengeResponseAuthentication` to `services.openssh.kbdInteractiveAuthentication`. + Reason is that the old name has been deprecated upstream. + Using the old option name will still work, but produce a warning. + +- The `pomerium-cli` command has been moved out of the `pomerium` package into + the `pomerium-cli` package, following upstream's repository split. If you are + using the `pomerium-cli` command, you should now install the `pomerium-cli` + package. + +- The option + [services.networking.networkmanager.enableFccUnlock](#opt-networking.networkmanager.enableFccUnlock) + was added to support FCC unlock procedures. Since release 1.18.4, the ModemManager + daemon no longer automatically performs the FCC unlock procedure by default. See + [the docs](https://modemmanager.org/docs/modemmanager/fcc-unlock/) for more details. + +- `programs.tmux` has a new option `plugins` that accepts a list of packages from the `tmuxPlugins` group. The specified packages are added to the system and loaded by `tmux`. + +- The polkit service, available at `security.polkit.enable`, is now disabled by default. It will automatically be enabled through services and desktop environments as needed. + +- The `hadoop` package has added support for `aarch64-linux` and `aarch64-darwin` as of 3.3.1 ([#158613](https://github.com/NixOS/nixpkgs/pull/158613)). + +- The `R` package now builds again on `aarch64-darwin` ([#158992](https://github.com/NixOS/nixpkgs/pull/158992)). + +- The `spark3` package has been updated from 3.1.2 to 3.2.1 ([#160075](https://github.com/NixOS/nixpkgs/pull/160075)): + + - Testing has been enabled for `aarch64-linux` in addition to `x86_64-linux`. + - The `spark3` package is now usable on `aarch64-darwin` as a result of [#158613](https://github.com/NixOS/nixpkgs/pull/158613) and [#158992](https://github.com/NixOS/nixpkgs/pull/158992). + +<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. --> |
