Oomd was killing a login session (user-*.slice/session-*.scope).
Quoting https://bugzilla.redhat.com/show_bug.cgi?id=2177722#c21:
> In F37 and prior the config was killing based on swap and pressure
> on user-*.slice/user@.service. In 7665e1796f
> it was changed to pressure only on system.slice and all slices under
> user.slice. The relevant point here is that this change now includes
> user-*.slice/session-*.scope which is the critical session bits
> you're seeing killed here.
>
> That session scope should be omitted. The config that I intended
> with the initial PR was for all slices under
> user.slice/user-*.slice/user@.service to be monitored, not for all
> slices under user.slice.
With the file removed:
$ oomctl | rg Path | sort
Path: /system.slice
Path: /user.slice/user-1000.slice/user@1000.service/app.slice
Path: /user.slice/user-1000.slice/user@1000.service/session.slice
See https://github.com/systemd/systemd/pull/26641.
This will allow upstream pull request (and the main branch after the pull
request has been merged) to be built with the new code. This doesn't do
anything for official rpm builds until the new code is part of the sources.

The socket exists and is enabled in the initrd. After switch-root, the system
goes into an infinite loop trying to stop the socket while incoming audit
messages trigger start jobs for the socket. This is a bug in the transaction
logic, that'll need to be fixed separately.
We need to preset the socket after the upgrade so that it remains enabled
by default. This should fix the boot issue, though it's not a complete fix,
because we actually want to allow people to disable the socket.
On initial install, the socket is covered by preset-all and gets enabled.
gcc has a new warning which caught a bug of int/enum mismatches.
And we would crash on some architectures when built with -D_FORTIFY_SOURCE=3
because of our malloc_usable_size() use.
This should resolve the build failure in F38 mass build.
- Fixes a few different issues (systemd-timesyncd connectivity problems, broken
emoji output on the console, crashes in pid1 unit dependency logic)
- CVE-2022-4415: systemd: coredump not respecting fs.suid_dumpable kernel
setting
As requested in https://github.com/rhinstaller/anaconda/pull/4368#discussion_r1043839809,
so that it's easier to depend on the appropriate package. Once we have the
signed version built, this provides might be dropped. But let's add it at least
for now so that there's a stable name to depend on.
While at it, let's drop ? from %{_isa}. Systemd is always archful.
This file changes rarely, but it does every one in a while. And since we have an
independent copy, we forget to adjust it. We have had already two bugs because
of this. I submitted a PR upstream to include pam_namespace (because that makes
sense for all distros), so the diff between upstream and us now is just the
inclusion of system-auth (which is not upstreamable).
Effectively, the only difference right now is that 'pam_keyinit force revoke'
is included. It was added upstream with the comment:
We want that systemd --user gets its own keyring as usual, even if the
barebones PAM snippet we ship upstream is used. If we don't do this we get
the basic keyring systemd --system sets up for us.
4047e4fb7b got things very wrong.
The trick with "[ $1 -eq 1 ]" doesn't work for transaction triggers
because the argument is not provided by rpm. We need to use a state
file to propagate the information from %post to %posttrans.

systemd-pcrphase and systemd-measure and initrd-* units are moved to systemd-udev.
systemd-udev should be part of the initrd, and those tools don't make much sense
in systems without hardware (i.e. containers). (systemd-measure could possibly be
useful, but we can always move it back if there's a good reason.)
- Remove swap policy. Default amount of swap (8GB?) is a lot lower than
what we use internally with the swap policy. Which frequently leads to
GNOME getting killed
(e.g. https://bugzilla.redhat.com/show_bug.cgi?id=1941170, and other
BZs not linked here). Internally we use 0.5x-1x size of physical memory
for swap via swapfiles (this will be documented in systemd upstream).
In simple cases of using more memory than is available (but without
memory pressure), the Kernel OOM killer can handle killing the
offending process.
- Expand the memory pressure policy to system.slice, user-.slice, and
all user owned slices. Support for ManagedOOM*= on user services was
added in https://github.com/systemd/systemd/pull/20690 which allows
us to be more fine grained on the pressure monitoring at the user
level. In addition to the system.slice and user-.slice PSI monitoring
this should result in a better systemd-oomd experience for desktop
systems.
