Bug description:
Hi,
I'm currently trying to use dovecot in a test scenario, but run into
the problem of a strange malfunction of apparmor.
What I do:
installed packages dovecot-core and dovecot-lmtp
(and of course apparmor)
Then I do (as root)
/usr/lib/dovecot/dovecot-lda -d hadmut <<ENDE
Subject: test
blabla
ENDE
which fails. strace shows:
14353 connect(6, {sa_family=AF_LOCAL, sun_path="/var/run/dovecot/config"},
110) = -1 EACCES (Permission denied)
...
14353 connect(7, {sa_family=AF_LOCAL, sun_path="/var/run/dovecot/auth-
userdb"}, 110) = -1 EACCES (Permission denied)
although file permissions are good, unix sockets exist and daemons are
listening.
/var/log/kern.log says
Dec 18 01:09:45 monstrum kernel: [34849.052767] audit: type=1400
audit(1482019785.088:143): apparmor="ALLOWED" operation="connect" info="Failed

comm="dovecot-lda" requested_mask="wr" denied_mask="wr" fsuid=0 ouid=134
which strangely says ALLOWED, but error=-13 as well,
and that even if dovecot-lda is in complain mode.
But when I put it into disable mode with
aa-disable /usr/lib/dovecot/dovecot-lda
then things work.
So
- it is definitely apparmor related, since aa-disable turns the problem off,
- it looks like a bug since aa-complain should never block anything,
- an ALLOWED-log should not blog
- there's an error=-13
regards
