Subject: [PATCH ucspi-vsock 0/7] Extract vsockserver-socketbinder and vsockserverd
Date: Fri, 19 Mar 2021 02:53:42 +0000 [thread overview]
Message-ID: <20210319025349.8839-1-hi@alyssa.is> (raw)
This series breaks vsockserver apart into two smaller programs,
vsockserver-socketbinder and vsockserverd. vsockserver-socketbinder
binds and listens on an AF_VSOCK socket and then execs into another
program with the socket as stdin. vsockserverd accepts connections to
a socket provided on stdin, and for each connection runs a program
with the connection socket on stdin and stdout. vsockserver is
replaced with a program that builds an argv that just combines these
two smaller programs and execs into it.
This design is based on s6[1]'s s6-ipcserver,
s6-ipcserver-socketbinder, and s6-ipcserverd programs.

vsock: get cid and port instead of just cid
vsock: check socket family before reading sockaddr
vsockserver: switch to a non-blocking socket
configure: create, to generate config.h
log: add die function
exec: add execzp()
