Check and log the default pretimeout governor configured in the kernel.
The pretimeout will not work unless at least one governor is available
and configured. This requires loading a kernel module manually.
Add support for managing and configuring watchdog pretimeout values if
the watchdog hardware supports it. The ping interval is adjusted to
account for a pretimeout so that it will still ping at half the timeout
interval before a pretimeout event would be triggered. By default the
pretimeout defaults to 0s or disabled.
The RuntimeWatchdogPreSec config option is added to allow the pretimeout
to be specified (similar to RuntimeWatchdogSec). The
RuntimeWatchdogPreUSec dbus property is added to override the pretimeout
value at runtime (similar to RuntimeWatchdogUSec). Setting the
pretimeout to 0s will disable the pretimeout.
For some reason Ubuntu Focal repositories now have `llvm-13` virtual
package which can't be installed, but successfully fools our check,
resulting in no clang/llvm being installed...
```
$ apt show llvm-13
Package: llvm-13
State: not a real package (virtual)
N: Can't select candidate version from package llvm-13 as it has no candidate
N: Can't select versions from package 'llvm-13' as it is purely virtual
N: No packages found
$ apt install --dry-run llvm-13
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package llvm-13 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'llvm-13' has no installation candidate

Let's split out the inner parts of verb_daemon_reload() as a function
daemon_reload() and then stop using the former outside of the verbs
logic, and instead call the latter whenever we need to reload the daemon
as auxiliary opeation.
This should make our logic more systematic as we don't have to provide
fake or misleading argc/argv to verb_daemon_reload() anymore.
Let's clean up our function naming a bit, and always name the
verb_xyz(), where the xyz maps to the command line verb as closely as
possible.
No actual code changes, just an attempt to make the systemctl sources a
bit more systematic, and less surprising.
There is no reason networkd refuses that. Especially, when multiple
downstream interfaces are connected to the same network, it is natural to
assign the same subnet prefix to them.
Prompted by #22571.
It's not clear why we rescheduled a service auto restart while a stop job for
the unit was pending. The comment claims that the unit shouldn't be restarted
but the code did reschedule an auto restart meanwhile.
In practice that was rarely an issue because the service waited for the next
auto restart to be rescheduled, letting the queued stop job to be proceed and
service_stop() to be called preventing the next restart to complete.
However when RestartSec=0, the timer expired right away making PID1 to
reschedule the unit again, making the timer expired right away... and so
on. This busy loop prevented PID1 to handle any queued jobs (and hence giving
no chance to the start rate limiting to trigger), which made the busy loop last
forever.
This patch breaks this loop by skipping the reschedule of the unit auto restart
and hence not depending on the value of u->restart_usec anymore.
Fixes: #13667
Some of the functions so far were named do_xyz(), others dump_xyz() and
even others test_xyz(). let's instead name them exactly like the verb
exposed in the command line, just prefixed with verb_
This renames the old analyze-verify.[ch] pair →
analyze-verify-util.[ch], because it's used by the test logic as well,
and by keeping it separate from the verify verb logic we don't have to
import the arg_xyz variables.
The new helper combines a bunch of steps every invocation of
unsetenv_erase() did so far: getenv() + strdup() + unsetenv_erase().
Let's unify this into one helper that is harder to use incorrectly. It's
in inspired by TAKE_PTR() in a way: get the env var out and invalidate
where it was before.
