dnsmasq 2.92 started converting binary content to ascii so the previous
invalid URL is no longer invalid as it's escaped.
So the test started failing: https://bugs.debian.org/1122015
Use a '|' character instead, which is not a valid URL character but it's
also not escaped by dnsmasq.

Alpine/postmarketOS build coreutils with --enable-single-binary=symlinks.
In that case, all commands provided by coreutils are symlink to
/usr/bin/coreutils, and it calls prctl(PR_SET_NAME, argv[0]), hence the comm
will be the path to the symlink.
This also makes not kill sleep command with SIGKILL in TEST-17-UDEV, that is
totally unnecessary.
The test cases are not related to systemd-resolved.
While moving the test cases, now userdbctl is used for obtaining UID/GID
for the dynamic user, as musl does not support nss module, hence getent
does not provide information about the dynamic user.
If there is no corresponding audit session, then the session ID is
prefixed with 'c', and in that case the session ID should be used as is
in bus path.
If sh is not bash, some builtin command behave slightly differently.
E.g. if sh is provided by busybox, its builtin test command does not check if
the path is a mount point or not, and 'test -w' only checks the access mode of
the inode. So, even if a readonly filesystem is mounted on a directory,
the test command may succeed.
To avoid such confusion, let's unconditionally use bash.
in pcrextend we destroy pcr 11, and if we are booted in a kernel that
has pcr11 sigs, we cannot use that signature anymore. hence, let's do
the nvpcr test first, before doing the pcrextend stuff.

Currently, if the libmount feature is disabled, we don't build libshared
and as a result skip building every other executable as well. Among
other things, this makes our nodeps CI builds kind of pointless since
hardly any code will be compiled.
Let's improve on the situation by making libmount properly optional in
libshared. Then, we only skip building the executables that actually
need libmount.

After bdb8e584f4 we stopped rebasing the
next elapse timestamp unconditionally and the only case where we'd do
that was when both last trigger and last inactive timestamps were empty.
This covered timer units during boot just fine, since they would have
neither of those timestamps set. However, persistent timers
(Persistent=yes) store their last trigger timestamp on a persistent
storage and load it back after reboot, so the rebasing was skipped in
this case.
To mitigate this, check the last_trigger timestamp is older than the
current machine boot - if so, that means that it came from a stamp file
of a persistent timer unit and we need to rebase it to make
RandomizedDelaySec= work properly.
Follow-up for bdb8e584f4.
Resolves: #39739
Add support for an empty Gateway= in [Network] to clear the existing
routes. This change will allow users to remove the default route from a
drop-in file.
We were getting a list of invocation IDs, picking one at random,
and then querying the unit. This is obviously racy.
TEST-74-AUX-UTILS.sh[2873]: + varlinkctl call /run/systemd/io.systemd.Manager io.systemd.Unit.List
'{"invocationID": "2052c9a5-7983-4f72-9910-c49e38c91dab"}'

The complicated varlink + jq callout is replaced by a simple systemctl call.
I think that's better to avoid a complicated jq expression.
Fixes https://github.com/systemd/systemd/issues/38647.
We cannot just use %m, because strerror returns a confusing error message
for ESRCH or ENOEXEC. udev code was doing a good job, but the error handling
was very verbose. Let's encapsulate the customized error messages in a
helper.
No functional change, except that the error messages have a slightly different
form now. The old messages were a bit better, but we don't have as much
flexibility in the new scheme. "Failed to resolve user 'foo': Unknown user"
should be good enough.
systemd-networkd cannot create the directory /run/systemd/resolve.hook/. Even
if the directory exists, it is not owned by systemd-network user/group, so
systemd-networkd cannot create socket file in the directory. Hence, if the
systemd-networkd-resolve-hook.socket unit is disabled, networkd fails to open
the varlink socket, and fail to start:
systemd-networkd[1304645]: Failed to bind to systemd-resolved hook Varlink socket: Permission denied
systemd-networkd[1304645]: Could not set up manager: Permission denied
systemd[1]: systemd-networkd.service: Main process exited, code=exited, status=1/FAILURE
systemd[1]: systemd-networkd.service: Failed with result 'exit-code'.
systemd[1]: Failed to start systemd-networkd.service - Network Management.
If the socket unit is disabled, that should mean the system administrator wants
to disable the feature. Let's not try to setup the varlink socket in that case.
Now the resolve hook feature can be toggled by enabling/disabling the socket
unit, let's drop the $SYSTEMD_NETWORK_RESOLVE_HOOK environment variable.

Commit 88fce09026 modified the
mount_bind() function, causing it to perform arithmetic on the uid_shift
parameter. However, it performs this arithmetic even when uid_shift was
UID_INVALID, which was not intended. This typically occurred when
mount_custom() was called for a simple bind mount without user
namespaces (and thus no rootidmap mount option).
This arithmetic (e.g., uid_shift + m->destination_uid) then wraps
around, resulting in the invalid ID 4294967295 ((uid_t)-1).
This bug manifests for users running systemd-nspawn with
--link-journal=host and --volatile=yes (but without --private-users),
causing systemd-tmpfiles to fail.
Make mount_bind() robust by checking if uid_shift is valid before using
it in arithmetic. If it is UID_INVALID, it defaults to a shift of 0 for
the ownership calculation, restoring correct behavior for plain bind
mounts while preserving the intended logic for ID-mapped mounts.
Fixes: #39714
Let's synthesize DNS RRs for leases handed out by our DHCP server. This
way local VMs can have resolvable hostnames locally.
This does not implement reverse look ups for now. We can add this
later in similar fashion.
Match the behaviour of the other test classes that use sd-run and
always create the mock tmpfs runtime dirs.
This will be needed as the new resolve.hook directory won't exist
on boot but will be needed by the test case.
This basically implements nss-myhostname, but natively in
systemd-resolved, so that the logic becomes available also for clients
using the local DNS stub for resolution or the D-Bus or Varlink APIs.
