The default behavior of check: false is going to change to true in the
future, see <https://github.com/mesonbuild/meson/issues/9300>.
Thus we are explicit about the desired behavior. The error in uname is
important but with test we check ourselves using returncode().
This fixes #556.

If supervise_daemon_args is not set *or empty*, it defaults to
`start_stop_daemon_args`. This is bad because supervise-daemon doesn't
accept the same options as `start-stop-daemon`. So if we set e.g.
`start_stop_daemon_args="--wait 50"`, but not `supervise_daemon_args`,
and the user adds `supervisor=supervise-daemon` to the corresponding
/etc/conf.d/<service> file, the service will fail to start due to
unrecognized option "wait".
It would be best to remove this fallback, but that might break some
existing scripts that depend on it. So this commit just changes it to
use `start_stop_daemon_args` as the default for `supervise_daemon_args`
only if `supervise_daemon_args` is not set at all, but not if it's
empty.
This at least simplifies workarounds; we can just add
`supervise_daemon_args="$supervise_daemon_args"` to init scripts.
This fixes #558.

Despite this being a 'deptree', it's actually
xmalloc'd in the same function (rc_deptree_update),
and so should be free'd, not rc_deptree_free'd,
as rc_deptree_load* wasn't used to allocate it.
```

Starting with grep version 3.8, the hwclock init script logs warnings
about stray backslashes:
> hwclock | * Setting system clock using the hardware clock [UTC] ...
> hwclock |grep: warning: stray \ before -
> hwclock |grep: warning: stray \ before -
This is caused by the check for existence of the `--noadjfile` argument
in function `get_noadjfile()`.
Replacing the affected logic with an explicit argument denoting the
pattern as such resolves the issue.
Fixes #548

As described in "Why nice levels are a placebo and have been for a very
long time, and no one seems to have noticed"[1], the Linux kernel in its
default configuration on many Linux distributions autogroups tasks by
session ID and "fairly" allocates CPU time among such autogroups. The
nice levels of tasks within each autogroup are only relative to
other tasks within the same autogroup. Effectively, this means that the
traditional nice level is rendered moot for tools like start-stop-daemon
and supervise-daemon, which start each daemon in its own session and
thus in its own autogroup. Linux does provide a means to change the
niceness of autogroups relative to each other, so let's have start-stop-
daemon and supervise-daemon make use of this feature where available so
that -N,--nicelevel/SSD_NICELEVEL will actually do what the user
intends. On systems where autogroups are not supported or are disabled,
this commit introduces no change in behavior.
Note that the setsid() call in the child process of start-stop-daemon is
moved to much earlier. This is necessary so that the new process will be
assigned to a new autogroup before the autogroup nicelevel is set. To
avoid inadvertently acquiring /dev/tty as the controlling terminal of
the new session after setsid() has given up the controlling terminal
inherited from the parent process, tty_fd is opened before the call to
setsid().

While refactoring the changes proposed in #533 a minor error was
introduced were the root service will now attempt to remount swap.
This will fail with the error message `mountinfo: 'swap' is not a
mountpoint`.

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.

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.

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.

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.

(This is analogous to the rc_stringlist change.)
This gives a hint to the compiler that allocations (return values)
from this function should be paired with a corresponding dealloc/free
function.

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').

The value of ${seed_dir} may have spaces in it, making the current
argument string building method unsafe. Instead, use positional
parameters to pass these arguments safely.

- drop initialization of some variables.
- use eerrorx where possible
- drop final cleanup instructions
|

There have been a number of subtle improvements and cleanups to seedrng,
including using openat and locking the directory fd instead of a
separate lock file. Also various stylistic cleanups.
This fixes #519.
