[Andreas Hasenack <2123821@xxxxxxxxxxxxxxxxxx>]

the rsyslog apparmor profile has a rule for /dev/log, which is a
symlink:

lrwxrwxrwx 1 root root 28 Sep 15 16:39 /dev/log ->
/run/systemd/journal/dev-log

But the base abstraction allows writing to that symlink's target:
/etc/apparmor.d/abstractions/base:  @{run}/systemd/journal/dev-log w,

And the rsyslog profile includes the base abstraction.

Bug description:
  On my Questing system running LXD containers, my kernel log is full of
  messages like:

  [  129.551382] audit: type=1400 audit(1757925628.229:1005):
  apparmor="DENIED" operation="sendmsg" class="file"
  namespace="root//lxd-q_<var-snap-lxd-common-lxd>" profile="rsyslogd"
  name="/run/systemd/journal/dev-log" pid=5370 comm="systemd-journal"
  requested_mask="r" denied_mask="r" fsuid=1000000 ouid=1000000

  One of my containers is named "q", hence the "root//lxd-q...". Some
  actual functionality is likely broken in the container.
