* buildLinux: take and propagate extraMakeFlagsBernardo Meurer2021-07-12
| | | | | | | This is just for practicity, as it allows users of buildLinux to pass along extra flags they need in the kernel's make invocation. This makes, for example, supporting LLVM _much_ easier, and could enable us in the future to provide clang-built kernels.
* linuxManualConfig: patch all shebangs in scripts/Bernardo Meurer2021-07-12
| | | | | | | | | | | | There are many scripts in `scripts/` which may be called by the build, depending on how the user chooses to configure the kernel. For example, `scripts/jobserver-exec` is called whenever the kernel is being built with LLVM tooling, and without this patch that build will fail due to the broken shebang. This patch makes us fix _all_ scripts, as well as add a dependency on python3Minimal, since a lot of the aforementioned scripts are written in Python3 instead of shell.
* linuxManualConfig: don't mangle `--build-id`Bernardo Meurer2021-07-10
| | | | | | | | | | | | | | | | In order to have our linux builds be reproducible we patch the `Makefile` to use `--build-id=none` as opposed to the default `--build-id=sha1`. The way we've been doing this, however, caused the flag to be mangled, and being set to `--build-id=none=sha1`. While bfd seems to parse this normally, lld will loudly complain that the flag does not exist: ``` linux> LD .tmp_vmlinux.kallsyms1 linux> ld.lld: error: unknown --build-id style: none=sha1 ``` With this change the flag is now correctly set to `--build-id=none`.

* linux: remove xen_dom0 feature entirelyAlyssa Ross2021-04-05
| | | | | | | Xen is now enabled unconditionally on kernels that support it, so the xen_dom0 feature doesn't do anything. The isXen attribute will now produce a deprecation warning and unconditionally return true. Passing in a custom value for isXen is no longer supported.

| | | | | | | This is a stdenv-rebuild, and should not be merged into master This reverts commit 8929989614589ee3acd070a6409b2b9700c92d65.
* lib: Clean up how linux and gcc config is specifiedJohn Ericson2021-01-21
| | | | | | | | | | | | | | | | The `platform` field is pointless nesting: it's just stuff that happens to be defined together, and that should be an implementation detail. This instead makes `linux-kernel` and `gcc` top level fields in platform configs. They join `rustc` there [all are optional], which was put there and not in `platform` in anticipation of a change like this. `linux-kernel.arch` in particular also becomes `linuxArch`, to match the other `*Arch`es. The next step after is this to combine the *specific* machines from `lib.systems.platforms` with `lib.systems.examples`, keeping just the "multiplatform" ones for defaulting.

* linux: omit build id (#106648)Arnout Engelen2020-12-23
| | | | | | | | Don't include an ​NT_GNU_BUILD_ID (that is randomly generated at build time). This improves the kernel reproducibility: when also disabling the MOUDLE_SIG and SECURITY_LOCKDOWN_LSM options the build is bit-by-bit reproducible.

* linux: do not depend on systemd indirectlyArian van Putten2020-04-28
| | | | | | | | | | | | | | | | | | | | | | utillinux depends on systemd because: * uuidd supports socket activation * lslogins can show recent journal entries * fstrim comes with a service file (and we use this in NixOS) * logger can write journal entries (See https://www.openembedded.org/pipermail/openembedded-core/2015-February/102069.html) systemd doesn't depend on utillinux but on utillinuxMinimal which is a version of utillinux without these features to avoid cyclic dependencies. With this change, the linux kernel (of which i don't fully understand why it would depend on util-linux in the first place, but this was added in https://github.com/NixOS/nixpkgs/pull/32137/files without too much explanation) depends on the minimal version of util-linux too. This makes it that every time we change build flags in systemd the linux kernel doesn't have to wastefully rebuild.

| | | | | | | | | | Go beyond the obvious setup hooks now, with a bit of sed, with a skipped case: - cc-wrapper's `dontlink`, because it already is handled. Also, in nix files escaping was manually added. EMP

* linux_5_2, linux_5_3: fixing nondeterminismDima2019-10-05
| | | | | | | | | | | | | | | | | | | | | | | | In 5.2 kernel a new mechanism was introduced which embeds the kernel headers in the kernel image and exposes them in procfs for simplified use by userland tools. It was introduced in https://github.com/torvalds/linux/commit/43d8ce9d65a54846d378545770991e65838981e0 and later modified a bit in https://github.com/torvalds/linux/commit/f7b101d33046a837c2aa4526cef28a3c785d7af2 The archive containing the header files had nondeterminism through the header files metadata - specifically `mtime`, but I also decided to normalize some other aspects just in case. In our default setup we currently compile this as a module, so to expose the headers to test the functionality `kheaders` needs to be loaded. See https://lkml.org/lkml/2019/10/4/1036 and https://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git/commit/?h=fixes&id=2cc99c9cdc8fde5e92e34f9655829449cebd3e00 I commented out the documentation part of the patch to make it cleanly apply to 5.2 and 5.3, see remark in the patch itself.

* linux_testing (5.2.0-rc1): fix build, include 'cpio' in nativeBuildInputsAustin Seipp2019-05-21
| | | | | | | | | | | | | | | | | | 81d4e65891f92e8e72c244da663c83c1e40dc919 automatically bumped linux_testing to 5.2.0-rc1, but the 5.2 merge window included a new feature adding compressed headers for compiled kernels into /proc/kheaders.tar.xz See https://github.com/torvalds/linux/commit/43d8ce9d65a54846d378545770991e65838981e0 This feature requires 'cpio' to now be included in nativeBuildInputs since it's used to construct that archive. This wasn't caught by Hydra since we turn off build of linuxPackages, but ideally we should at least build the kernel in the future (linux_testing itself.)

* treewide: disable pie in more placesMatthew Bauer2018-11-13
| | | | | | | | | | | | Some packages don’t work correctly with pie. Here I disable it for: - busybox - linux kernel - kexectools I also get rid of the Musl conditional for disabling pie in GCC and Binutils. Some day we might want to enable PIE without Musl and it will be useful to have the *just* work with our compiler and linkers.

* kernel: Reduce peak disk usage during buildTuomas Tynkkynen2018-07-24
| | | | | | | | | | | Since commit f620b1b693ec25af, the build directory is located inside the source directory. Thus, the `cp -dpR` copies gigabytes worth of .o files only to be deleted later on when we trim all non-essential files from `$dev/lib/modules/${modDirVersion}/source/` thus causing a significant amount of wasted I/O and peak disk usage. As `cp` doesn't come with a `--exclude` flag, use rsync. And throw out the Documentation folder while at it.

* linux: translate config to structured configDan Peebles2018-06-30
| | | | | | | | | | | | Instead of using a string to describe kernel config, use a nix attribute set, then converted to a string. - allows to override the config, aka convert 'yes' into 'modules' or vice-versa - while for now merging different configs is still crude (last spec wins), at least there should be only one CONFIG_XYZ value compared to the current string config where the first defined would be used and others ignored. [initial idea by copumpkin in 2016, a major rebase to 2018 by teto]
* linuxPackages_custom: fix missing argument and add testRobert Hensing2018-04-07
| | | | | | | | | | | | | | | The required argument 'hostPlatform' was missing from linuxPackages_custom's call to linuxManualConfig. In order to prevent this in the future, this commit adds linuxPackages_custom_tinyconfig_kernel so linuxPackages_custom gets tested. This also adds linuxConfig, to derivate default linux configurations via make defconfig, make tinyconfig, etc. Closes #38034. Signed-off-by: Austin Seipp <aseipp@pobox.com>

* kernel: buildLinux replaces import ./generic.nixMatthieu Coudron2018-02-07
| | | | | | | - defined buildLinux as generic.nix instead of manual-config.nix. This makes kernel derivations a tad more similar to your typical derivations. - moved $buildRoot to within the source folder, this way it doesn't have to be created before the unpackPhase and make it easier to work on kernel source without running the unpackPhase
