2022-09-02init.d/root: also remount / with options provided in /etc/fstabSören Tempel
Without this commit, the root OpenRC service remounts all mounted filesystems (except /) with the options defined in /etc/fstab via fstabinfo. It is presently unclear to me why / was excluded from remounting in 497ff7ee41168d863971efb52e2ca6b42f765832 and unfortunately neither the commit nor the associated Bugzilla issue [1] provides further information on this. At Alpine, our initramfs does currently not remount / with all options defined in /etc/fstab [2]. As part of the discussion on the Alpine side of things we wondered why OpenRC does not remount / since this would be the easier solution for us. For this reason, this commit changes the behavior of the OpenRC root services accordingly to also remount / with the options defined in /etc/fstab. [1]: https://bugs.gentoo.org/401573 [2]: https://gitlab.alpinelinux.org/alpine/mkinitfs/-/merge_requests/103 This fixes #533.
2022-09-02start-stop-daemon: use vfork to avoid racesArusekk
While running `rc-service start docker` on Gentoo, I found that the command does not start the service 90% of the time, with an enigmatic 'service crashed' message. The root cause of this is apparently rc-service spawning a pty, running start-stop-daemon inside that pty, and exitting, before start-stop-daemon child process calls setsid(), which results in the child process being killed with SIGHUP (SI_KERNEL). Theoretically this bug was present ever since the file was created in 5af58b45146a ("Rewrite the core parts in C. We now provide...") (or even before that), but it should have been only a minor issue before 45bd125dccdc ("Use a pty for prefixed output instead of pipes for..."). Not sure why nobody has had the issue so far (it has been present for almost 15 years). As here setsid() is the last call before execve(), the most natural locking mechanism is vfork(), as it gives back control to parent process only after execve() or process termination. So this way the bug can be fixed by adding a single letter. :-) Another way to ensure this would be using an O_CLOEXEC file descriptor or some custom lock, which would need to be released not before setsid(). Fixes: 5af58b45146a ("Rewrite the core parts in C. We now provide...") Fixes #532.
2022-07-21openrc: fix help messagesxdavidwu
The two lines seem to both belong to --override, but made into seperate array elements accidentally, making options after --override and their help mismatch. This fixes it.
2022-07-03fix quoting of loggers in start-stop-daemonpsykose
previously broken in 6034866d1c74d5a23eb9f3e0ebf40c9d278aac93 caused *_logger options to be passed unquoted, so `error_logger="logger -t .."` would pass -t to s-s-d and fail to start the service. Fixes: #531

2022-05-08librc: mark rc_deptree_* functions as mallocsSam James

2022-05-08librc: mark stringlist functions as mallocsSam James
This gives a hint to the compiler that allocations (return values) from this function should be paired with a corresponding dealloc/free function In this case, it means that every rc_stringlist that rc_stringlist_new() returns should eventually be freed by calling rc_stringlist_free(ptr) where ptr is the relevant rc_stringlist. We have to add a test for this into the build system because only GCC supports this for now. In future, we might be able to use meson's has_function_attribute (it does support 'malloc', just not AFAICT 'malloc with arguments'). Signed-off-by: Sam James <sam@gentoo.org>

2022-03-26Use seedrng for seeding the random number generatorJason A. Donenfeld
The RNG can't actually be seeded from a shell script, due to the reliance on ioctls. For this reason, the seedrng project provides a basic script meant to be copy and pasted into projects like OpenRC and tweaked as needed: https://git.zx2c4.com/seedrng/about/ This commit imports it into OpenRC and wires up /etc/init.d/urandom to call it. It shouldn't be called by other things on the system, so it lives in rc_sbindir. Closes #506. Closes #507. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
