[Bug 1686759] [NEW] apparmor denies sendmsg to /run/systemd/journal/socket

[Marius Gedminas]

Public bug reported:

While debugging why Polari can no longer connect to IRC servers after an
upgrade to Ubuntu 17.04, I noticed the following errors in my journal:

    Bal 27 18:05:56 platonas audit[4869]: AVC apparmor="DENIED"
operation="sendmsg" profile="/usr/lib/telepathy/mission-control-5"
name="/run/systemd/journal/socket" pid=4869 comm="mission-control"
requested_mask="w" denied_mask="w" fsuid=1000 ouid=0


(repeated many times)

I also see

    Bal 27 18:05:56 platonas mission-control-5[4869]: (process:4869):
mcd-WARNING **: got error: Account idle/irc/mgedmin0 disconnected with
reason 3

so somehow log messages from mission-control-5 still make it, despite
the denied journal connection (via syslog maybe?).
