It is only added in the one place where we actually try to set the
setting to a new value. Before we were testing if we can set to it the
existing value, which was a noop. We could still get a permission error,
but this is the first place where we would propagate EROFS.
From packit/rawhide-arm64 logs:
Assertion 'limit >= INT_MAX || get_process_ppid(limit+1, NULL) == -ESRCH' failed at src/test/test-process-util.c:855, function test_get_process_ppid(). Aborting.

The kernel has a few different limits. In particular kernel.threads-max can be
set to some lower value, and kernel.pid_max can be set to a higher value. This
is nice because it reduces PID reuse, even if the number of threads that is
allowed is limited. But the tests assumed that we cannot have a thread with
PID above MIN(kernel.threads-max, kernel.pid_max-1), which is not valid.
So let's rework the whole thing: let's expose the helpers to read
kernel.threads-max and kernel.pid_max, and print what they return in tests.
procfs_tasks_get_limit() was something that is only used in tests, and wasn't
very well defined, so let's drop it.
Fixes#21193.
This test makes assumptions on the availability of some mappings contained in
kbd-model-map and therefore strongly relies on the version shipped by
upstream. IOW the test is likely to fail if it's installed on a system with a
more comprehensive kbd-model-map.
This patch makes the upstream kbd-model-map file available via a symlink in
test/testdata/test-keymap-util dir and makes sure that this specific version is
always used by test-keymap-util regardless of whether the test is installed and
run on a different system or directly run (optionally via meson) from the
project working dir.
When `SELinuxContext=` parameter is prefixed with `-`, the documentation states
that any errors determining or changing context should be ignored, but this
doesn't actually happen and the service may fail with `229/SELINUX_CONTEXT`.
Fix by adding checks to `context->selinux_context_ignore`.
Closes: #21057
Doing start rate limit checks before doing condition checks made
condition check failures count towards the start rate limit which
broke existing assumptions (see #21025). Run the rate limit checks
after the condition checks again to restore the previous behaviour.
The checks for finding a new available address in the pool were broken in two
ways: not using UINT32_TO_PTR() on hashmap lookups resulted in false negatives,
and the check wasn't skipping the server address if that was part of the pool.
Move the check for available addresses to a small helper function and fix both
issues, and also add a check to the REQUEST code for the server address.
The DHCP server configuration supports setting a maximum lease time, but old
leases are never actually cleared out if the client doesn't send a RELEASE.
This causes the pool to run out of addresses on networks where clients just
disappear, which is a fairly common occurrence on wireless networks.
Fix this by cleaning up expired leases before processing client requests, so
addresses can be reused for new clients.
This makes sure that a switch like --bind=:/foo does the right thing if
user namespacing is one: the backing dir should be owned by the
container's root UID not the host's. Thus, whenever the source path is
left empty and we automatically generate a source dir as temporary
directory, ensure it's owned by the right UID.
Fixes: #20869
This shows the cgroup tree of the root slice of the container now, by
querying the cgroup pid tree via the bus instead of going directly to
the cgroupfs.
A fallback is kept for really old systemd versions where querying the
PID tree was not available.
Fixes: #20958
Otherwise we likely show rubbish because even in local containers we
nowadays have cgroup namespacing, hence we likely can't access the
cgroup tree from the host at the same place as inside the container.
