John,

I'm using Ubuntu Trusty with Utopic HWE, so my apparmor is from Trusty.
I didn't install anything from backports or Utopic by hand to not mess package system and LTS state of distribution.
But somehow the system does not behave like trusty.

Note that I've updated this system from 12.04 w/ Trusty HWE to 14.04
with do-release-upgrade few months ago.

Bug description:
  Hi.

  I've noticed that apparmor loads /usr/sbin/rsyslogd profile for
  completely unrelated processes:

  Feb 25 08:36:19 emma kernel: [  134.796218] audit: type=1400 audit(1424842579.429:245): apparmor="DENIED" operation="sendmsg" profile="/usr/sbin/rsyslogd" name="/dev/log" pid=4002 comm="sshd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

  I'm not sure how apparmor decides which profile to use for which task, but is shouldn't load '/usr/sbin/rsyslogd' profile for sshd/ntpd/etc.
