This should not change any behavior.
Just a preparation for a later commit which introduces
request_call_netlink_async().

This should not change any behavior, as req->netlink_handler is always
qdisc_handler or tclass_handler.

get_pretty_hostname() so far had semantics not in line with our usual
ones: the return parameter was actually freed before the return string
written into it, because that's what parse_env_file() does. Moreover,
when the value was not set it would return NULL but succeed.
Let's normalize this, and only fill in the return value if there's
something set, and never read from it, like we usually do with return
parameter, and in particular those named "ret_xyz".
The existing callers don't really care about the differences, but it's
nicer to normalize behaviour to minimize surprises.

so the CLI interface is now similar to `systemctl`, i.e. if no unit name
suffix is provided, assume `.service`.
Fixes: #20492
Before:
```
$ systemd-cgls --unit user@1000
Failed to query unit control group path: Invalid argument
Failed to list cgroup tree: Invalid argument

After:
```
$ build/systemd-cgls --unit user@1000
Unit user@1000.service (/user.slice/user-1000.slice/user@1000.service):

Unprivileged overlayfs is supported since Linux 5.11. The only
change needed to get ExtensionDirectories to work is to avoid
hard-coding the staging directory to the system manager runtime
directory, everything else just works (TM).

Resolves: #20054
|
|
This mirrors a similar check in Linux kernel 5.16
(9dcc38e2813e0cd3b195940c98b181ce6ede8f20) that raised the
RLIMIT_MEMLOCK to 8M.
This change does two things: raise the default limit for nspawn
containers (where we try to mimic closely what the kernel does), and
bump it when running on old kernels which still have the lower setting.
Fixes: #16300

The first ExecStartPre or the first ExecStart commands would get the metadata,
but not the subsequent ones. Also check that we do not pass it in
ExecStartPost.
|
|
This fixes the following case:
OnFailure= would be spawned correctly, but OnSuccess= would be
spawned without the MONITOR_* metadata, because we'd "collect" the unit
that started successfully. So let's block cleanup while we have a job
running for the handler. The job cannot last infinitely, so at some point
we'll be able to collect both.
|
|
This would be very confusing to users, so let's warn if they configured the
same handler for multiple units and we're not running it as expected.
|
|
We already logged what we are spawning, but not so much why. Let's
add this, so it's easier to distinguish execstartpre/execstart/execstartpost
and such.
|
|
|
|
|
|
|
|
The test would fail when the the same handler was used for multiple
*failing* units. We need to call 'reset-failed' to let the manager forget
about the earlier ones.
systemd-analyze log-target console is removed, because it's easier to follow
the logs if logging it to the journal.
|
|
After the cleanup, it was fairly easy to see the wrong variable name ;)

OnFailure/OnSuccess
Remove the list logic, and simply skip passing metadata if more than one
unit triggered an OnFailure/OnSuccess handler.
Instead of a single env var to loop over, provide each separate item
as its own variable.

Backward incompatible change to avoid returning 'skipped' if a condition causes
a job activation to be skipped when using StartUnitWithFlags().
Job results are broadcasted, so it is theoretically possible that existing
software could get confused if they see this result.

This stuff is sufficiently different from the rest of main.c, let's move
it to its own .c/.h file, to make main.c a bit shorter.
No code changes, just some refactoring.

The only piece missing was to somehow make /proc appear in the
new user+mount namespace. It is not possible to mount a new
/proc instance, not even with hidepid=invisible,subset=pid, in
a user namespace unless a PID namespace is created too (and also
at the same time as the other namespaces, it is not possible to
mount a new /proc in a child process that creates a PID namespace
forked from a parent that created a user+mount namespace, it has
to happen at the same time).
Use the host's /proc with a bind-mount as a fallback for this
case. User session services would already run with it, so
nothing is lost.

get_process_cmdline calls malloc, which should be avoid in signal handler.

This matches naming of the 'delayed_action' field we already have. It's
similar in both type and concept, and hence should be named similarly.
|
|
The function has nothing to do with any Manager object, hence drop that
from the name. And it actually looks something up by handle *action* not
by *handle*, hence the old name was a bit misnomer. Let's call it
handle_action_lookup(), as it queries handle action metainfo for a
handle action.
Also, let's make sure it behaves more like our usual functions that
lookup some fixed data from some enum value/int: let's return NULL if we
don't find it.
|
|
|
|
|
|
It stores meta-info about various HandleActions, hence let's name it
after that. The fact that it can be seen as stored inside some form of a
table is an implementation detail of logind-action.c, and should not
leak into other modules, hence let's focus on what it is, not how it is
stored.
|
|
The old macro will double evaluation and has no protection against
operator precedence issues. Let's fix that by using an inline func
instead, which also gives us typesafety.

RANDOM_BLOCK has existed for a long time, but RANDOM_ALLOW_INSECURE was
added more recently, leading to an awkward relationship between the two.
It turns out that only one, RANDOM_BLOCK, is needed.
RANDOM_BLOCK means return cryptographically secure numbers no matter
what. If it's not set, it means try to do that, but if it fails, fall
back to using unseeded randomness.
This part of falling back to unseeded randomness is the intent of
GRND_INSECURE, which is what RANDOM_ALLOW_INSECURE previously aliased.
Rather than having an additional flag for that, it makes more sense to
just use it whenever RANDOM_BLOCK is not set. This saves us the overhead
of having to open up /dev/urandom.
Additionally, when getrandom returns too little data, but not zero data,
we currently fall back to using /dev/urandom if RANDOM_BLOCK is not set.
This doesn't quite make sense, because if getrandom returned seeded data
once, then it will forever after return the same thing as whatever
/dev/urandom does. So in that case, we should just loop again.
Since there's never really a time where /dev/urandom is able to return
some easily but more with difficulty, we can also get rid of
RANDOM_EXTEND_WITH_PSEUDO. Once the RNG is initialized, bytes
should just flow normally.
This also makes RANDOM_MAY_FAIL obsolete, because the only case this ran
was where we'd fall back to /dev/urandom on old kernels and return
GRND_INSECURE bytes on new kernels. So also get rid of that flag.
Finally, since we're always able to use GRND_INSECURE on newer kernels,
and we only fall back to /dev/urandom on older kernels, also only fall
back to using RDRAND on those older kernels. There, the only reason to
have RDRAND is to avoid a kmsg entry about unseeded randomness.
The result of this commit is that we now cascade like this:
- Use getrandom(0) if RANDOM_BLOCK.
- Use getrandom(GRND_INSECURE) if !RANDOM_BLOCK.
- Use /dev/urandom if !RANDOM_BLOCK and no GRND_INSECURE support.
- Use /dev/urandom if no getrandom() support.
- Use RDRAND if we would use /dev/urandom for any of the above reasons
and RANDOM_ALLOW_RDRAND is set.

Add srpm_build_deps key to the Packit config to specify needed dependencies for SRPM build
and indicate to build SRPM in Copr.

This is used by ExtensionDirectories too, as they are bind-mounted in the
propagate directory to check the extension-release files
