[Bug 2123821] Re: bad restriction: apparmor="DENIED" [...] namespace="root//lxd-n_<var-snap-lxd-common-lxd>" profile="rsyslogd" name="/run/systemd/journal/dev-log"

 

I can reproduce the issue even after rebooting the host, and with new
containers (i.e. I deleted the existing ones and recreated them: the
issue immediately shows up.) Maybe the version of the lxd snap can play
a role? I'm running 6.5-22da890 from latest/stable.

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.
