This test would normally get stuck when trying to mount the verity image
due to:
systemd-udevd[299]: dm-0: '/usr/sbin/dmsetup udevflags 6293812'(err) '==371==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.'
systemd-udevd[299]: dm-0: Process '/usr/sbin/dmsetup udevflags 6293812' failed with exit code 1
...
systemd-udevd[299]: dm-0: '/usr/sbin/dmsetup udevcomplete 6293812'(err) '==372==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.'
systemd-udevd[299]: dm-0: Process '/usr/sbin/dmsetup udevcomplete 6293812' failed with exit code 1.
systemd-udevd[299]: dm-0: Command "/usr/sbin/dmsetup udevcomplete 6293812" returned 1 (error), ignoring.
so let's add a simple udev rule which sets $LD_PRELOAD for the block
subsystem.
Also, install the ASan library along with necessary dependencies into
the verity minimal image, to get rid of the annoying (yet harmless)
errors about missing library from $LD_LIBRARY.
The fuzzer seems to have no trouble with this sample. It seems that the
problem reported in the bug is not caused by the match parsing code. But
let's add the sample just in case.
https://bugzilla.redhat.com/show_bug.cgi?id=1935084
This fuzzer is based on test-bus-match. Even the initial corpus is
derived entirely from it.
https://bugzilla.redhat.com/show_bug.cgi?id=1935084 shows an crash
in bus_match_parse(). I checked the coverage stats on oss-fuzz, and
sadly existing fuzzing did not cover this code at all.
When running integration tests under sanitizers D-Bus fails to
shutdown cleanly, causing unnecessary noise in the logs:
```
dbus-daemon[272]: ==272==LeakSanitizer has encountered a fatal error.
dbus-daemon[272]: ==272==HINT: For debugging, try setting environment variable LSAN_OPTIONS=verbosity=1:log_threads=1
dbus-daemon[272]: ==272==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc)
```
Since we're not "sanitizing" D-Bus anyway let's disable LSan's at_exit
check for the dbus.service to get rid of this error.
freep() has it's own definition, so I missed it in fd421c4adc.
Again, there is a small growth, but the compiler should be able to optimize it away:

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=31055.
--no-legend is replaced by --legend=no.
--quiet now implies --legend=no, but --legend=yes may be used to override that.
--quiet controls hints and warnings and such, and --legend controls just the
legends. I think it makes sense to allow both to controlled independently, in
particular --quiet --legend makes sense when using systemctl in a script to
provide some user-visible output.
Fixes#18560.
When a subshell is used ('make' or 'make all') the LOOPDEV environment
variable, which is used to store the opened loop device, is lost.
So the cleanup on trap/exit doesn't do anything, and the loop
device used to mount the test image is left around.
Avoid using a subshell to fix the issue.
With all the preparatory work in previous PRs, we can now call static destructors
repeatedly without issue. We need to do it here so that global variables allocated
during parsing are properly freed.
The source package in the apt cache might be older than the
packaging from salsa.debian.org/systemd-team/systemd so it might not
list all the current binary packages.
This is currently the case for systemd-timesyncd, so TEST-30 fails.
Simply grep the control file rather than using apt-cache when iterating
over the packages contents.
Similar to DHCPv4's UseHostname option, add a UseFQDN config option in
[DHCPv6] to set the system's transient hostname if the FQDN option is
set in the DHCPv6 response from the server.
Add 'reattach' verb to portablectl, and corresponding DBUS interface
to systemd-portabled.
Takes the same parameters as 'attach', but it will do a 'detach' (and
it will refuse to proceed if it cannot be done) first, matching on
the unversioned prefix of the new image. Eg:
portablectl reattach /tmp/foo_2.raw
will cause foo_1.raw to be detached, and foo_2.raw to be attached.
The key difference with a manual 'detach old' plus 'attach new' is that
the running units are not disturbed until after the attach completed,
and if --now is passed they are then restarted.
A 'detach' is not allowed normally if the units are running.
By using a restart-after-deploy method, 'reattach' allows for minimal
interruption of service and also for features that only work on restart
(eg: file descriptor store) to work as intended.
The DBUS interface returns two lists: first the removals from the detach
that were not immediately re-added in the attach, so that the caller
can stop the relevant units, and then the list of additions that are
either new or updates, so that the caller can restart/enable the
relevant units. portablectl already implements this with the existing
--now/--enable switches.
