Subject: [PATCH] path: stop watching path specs once we triggered the target
unit

We start watching them again once we get a notification that triggered
unit entered inactive or failed state.

Subject: [PATCH] core: when restarting services, don't close fds

We would close all the stored fds in service_release_resources(), which of
course broke the whole concept of storing fds over service restart.

Fixes #4408.

Subject: [PATCH] unit: rework a bit how we keep the service fdstore from being
destroyed during service restart

When preparing for a restart we quickly go through the DEAD/INACTIVE
service state before entering AUTO_RESTART. When doing this, we need to
make sure we don't destroy the FD store. Previously this was done by
checking the failure state of the unit, and keeping the FD store around
when the unit failed, under the assumption that the restart logic will
then get into action.

This is not entirely correct howver, as there might be failure states
that will no result in restarts.

With this commit we slightly alter the logic: a ref counter for the fd
store is added, that is increased right before we handle the restart
logic, and decreased again right-after.

This should ensure that the fdstore lives exactly as long as it needs.

Follow-up for f0bfbfac43b7faa68ef1bb2ad659c191b9ec85d2.

get NULL

We generally expect destructors to not complain if a NULL argument is passed.

Closes #12400.

Subject: [PATCH] mount: don't propagate errors from mount_setup_unit() further
up

If we can't process a specific line in /proc/self/mountinfo we should
log about it (which we do), but this should not affect other lines, nor
further processing of mount units. Let's keep these failures local.

Fixes: #10874

Subject: [PATCH] mount: when allocating a Mount object based on
/proc/self/mountinfo mark it so

Let's set 'from_proc_self_mountinfo' right away, since we know its from
there. This is important so that when the load queue is dispatched (and
thus mount_load() called) this
fact is already known.

Subject: [PATCH] core: rework StopWhenUnneeded= logic

Previously, we'd act immediately on StopWhenUnneeded= when a unit state
changes. With this rework we'll maintain a queue instead: whenever
there's the chance that StopWhenUneeded= might have an effect we enqueue
the unit, and process it later when we have nothing better to do.

This should make the implementation a bit more reliable, as the unit notify event
cannot immediately enqueue tons of side-effect jobs that might
contradict each other, but we do so only in a strictly ordered fashion,
from the main event loop.

This slightly changes the check when to consider a unit "unneeded".
Previously, we'd assume that a unit in "deactivating" state could also
be cleaned up. With this new logic we'll only consider units unneeded
that are fully up and have no job queued. This means that whenever
there's something pending for a unit we won't clean it up.

Subject: [PATCH] sd-bus: when attached to an sd-event loop, disconnect on
processing errors

If we can't process the bus for some reason we shouldn't just disable
the event source, but log something and give up on the connection. Hence
do that, and disconnect.

Subject: [PATCH] sd-journal: remove the dead code and actually fix #14695

journal_file_fstat() returns an error if we call it on already unlinked
journal file and hence we never reach remove_file_real() which is the
entire point.

I must have made some mistake while testing the fix that got me thinking
the issue is gone while opposite was true.

Fixes #14695

Subject: [PATCH] swap: adjust swap.c in a similar way to what we just did to
mount.c

Also drop the redundant states and make all similar changes too.
Thankfully the swap.c state engine is much simpler than mount.c's, hence
this should be easier to digest.

Subject: [PATCH] swap: finish the secondary swap units' jobs if deactivation
of the primary swap unit fails

Currently, if deactivation of the primary swap unit fails:

# LANG=C systemctl --no-pager stop dev-mapper-fedora\\x2dswap.swap
Job for dev-mapper-fedora\x2dswap.swap failed.
See "systemctl status "dev-mapper-fedora\\x2dswap.swap"" and "journalctl -xe" for details.

then there are still the running stop jobs for all the secondary swap units
that follow the primary one:

# systemctl list-jobs
JOB UNIT TYPE STATE
3233 dev-disk-by\x2duuid-2dc8b9b1\x2da0a5\x2d44d8\x2d89c4\x2d6cdd26cd5ce0.swap stop running
3232 dev-dm\x2d1.swap stop running
3231 dev-disk-by\x2did-dm\x2duuid\x2dLVM\x2dyuXWpCCIurGzz2nkGCVnUFSi7GH6E3ZcQjkKLnF0Fil0RJmhoLN8fcOnDybWCMTj.swap stop running
3230 dev-disk-by\x2did-dm\x2dname\x2dfedora\x2dswap.swap stop running
3234 dev-fedora-swap.swap stop running

5 jobs listed.

This remains endlessly because their JobTimeoutUSec is infinity:

# LANG=C systemctl show -p JobTimeoutUSec dev-fedora-swap.swap
JobTimeoutUSec=infinity

If this issue happens during system shutdown, the system shutdown appears to
get hang and the system will be forcibly shutdown or rebooted 30 minutes later
by the following configuration:

# grep -E "^JobTimeout" /usr/lib/systemd/system/reboot.target
JobTimeoutSec=30min
JobTimeoutAction=reboot-force

The scenario in the real world seems that there is some service unit with
KillMode=none, processes whose memory is being swapped out are not killed
during stop operation in the service unit and then swapoff command fails.

On the other hand, it works well in successful case of swapoff command because
the secondary jobs monitor /proc/swaps file and can detect deletion of the
corresponding swap file.

This commit fixes the issue by finishing the secondary swap units' jobs if
deactivation of the primary swap unit fails.

Fixes: #11577

Subject: [PATCH] udev-rules: make tape-changers also apprear in
/dev/tape/by-path/

It is important to be able to access tape changer ("Medium Changers") by
persistant name.
While tape devices can be accessed via /dev/tape/by-id/ and
/dev/tape/by-path/, tape-changers could only be accessed by
/dev/tape/by-id/.
However, in some cases, especially when accessing Amazon Webservice
Storage Gateway VTLs (or accessing iSCSI VTLs in general?) this does not
work, as all tape devices and the tape changer have the same ENV{ID_SERIAL}.
The results is, that only the last device is available in
/dev/tape/by-id/, as the former devices have been overwritten.

As this behavior is hard to change without breaking consistentcy,
this additional device in /dev/tape/by-path/ can be used to access the medium changes.
The tape devices can also be accessed by this path.

The content of the directory will now look like:

# SCSI tape device, rewind (unchanged)
/dev/tape/by-path/$env{ID_PATH} -> ../../st*

# SCSI tape device, no-rewind (unchanged)
/dev/tape/by-path/$env{ID_PATH}-nst -> ../../nst*

# SCSI tape changer device (newly added)
/dev/tape/by-path/$env{ID_PATH}-changer -> ../../sg*

Tape devices and tape changer have different ID_PATHs.
SCSI tape changer get the suffix "-changer"
to make them better distinguishable from tape devices.
