eb3635dd1f swclock: fix codeql warning and upgrade to futimens
this was reported by codeql's scan as a TOCTOU bug. while that's true in
theory, i don't believe it would've had any practical effect.

a better justification for this change might be the fact that it
upgrades from `utime` (which is depreciated by POSIX [0]) to `futimens`.

459783bbad openrc: avoid unnecessary malloc inside sig-handler
malloc (called by xasprintf) is not async-signal-safe. beside, the
string here is constant, so there's no need to malloc it all.

eerrorx isn't async-signal-safe either (due to calling fprintf and exit)
but consequence of them are _typically_ not as grave as calling malloc
while it's internal state is inconsistent.

19f329d2f4 openrc, openrc-run: Fix -Wstrict-prototypes
These become fine with C23 because () starts to mean (void) then, but for
previous language versions, it's deprecated, and it causes an annoying
warning when building with Clang by default.

Plus, GCC lacks specific flags to trigger what C23 *does* ban, so a lot
of people are going around building with -Wstrict-prototypes, so let's
just fix this to be consistent with the rest of the codebase anyway
to fend off false positive reports.

9dfd2b2737 start-stop-daemon, supervise-daemon: use closefrom()/close_range()
On systems with a very large RLIMIT_NOFILE, calling close() in a loop
from 3 to getdtablesize() effects an enormous number of system calls.
There are better alternatives. Both BSD and Linux have the closefrom()
system call that closes all file descriptors with indices not less than
a specified minimum. Have start-stop-daemon call closefrom() on systems
where it's implemented, falling back to the old loop elsewhere.

Likewise, calling fcntl(i, F_SETFD, FD_CLOEXEC) in a loop from 3 to
getdtablesize() raises a similar performance concern. Linux 5.11 and
onward has a close_range() system call with a CLOSE_RANGE_CLOEXEC flag
that sets the FD_CLOEXEC flag on all file descriptors in a specified
range. Have supervise-daemon utilize this feature on systems where it's
implemented, falling back to the old loop elsewhere.

de295bd0c6 start-stop-daemon: remove unnecessary carve-out for pipe FD
1364e6631c exempted the write end of the
synchronization pipe from the close() loop in the child process, but
this is unnecessary, as the pipe is opened with O_CLOEXEC, and the child
process calls execvp() soon after the close() loop, with the intervening
code not needing the pipe. Indeed, the pipe only needs to remain open in
the child process until after the call to setsid(), which occurs well
before the close() loop. So, eliminate the needless carve-out from the
close() loop, in preparation for introducing closefrom().

35077afb68 build: fix run_command warning
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().

953172c6c6 supervise-daemon: don't overwrite empty supervise_daemon_args
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.

0525de4f18 librc-depend: fix -Wmismatched-dealloc
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,

9380347f04 Avoid warning on grep 3.8 in hwclock
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

112b69860f start-stop-daemon, supervise-daemon: set autogroup nicelevel
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().
