Title:
aa-logprof crash on #include <directory>
Status in AppArmor:
Fix Released
Status in AppArmor 2.9 series:
Fix Committed
Status in apparmor package in Ubuntu:
New
Bug description:
aa-logprof crashes on profiles that contain an #include <directory>
_if_ there are events for this profile.
2.9 crash:
# aa-logprof -f /tmp/syslog
Lese Logeinträge von /tmp/syslog.
Aktualisiere AppArmor-Profile in /etc/apparmor.d.
Traceback (most recent call last):

Reproducer: (slightly faked log event, apache didn't request network raw)
aa-logprof -f <(echo 'Jul 2 06:39:54 piorun kernel: [5579093.070893]
audit: type=1400 audit(1435811994.122:696484): apparmor="ALLOWED"
operation="accept" profile="/usr/sbin/apache2" pid=18852
comm="apache2" lport=443 family="inet6" sock_type="raw" protocol=6')
Note: If you test with old logs, it doesn't happen always because
is_known_rule() / profile_known_*() exits as soon as it finds a match,
and the order of include files is random - which means it doesn't
always loop until it hits the directory include.
I'm afraid that this affects the profile_known_*() functions for all
rule types.
