Hello, for some (not yet known) reason, we get file_perm events without request_mask set, which causes an aa-logprof crash.
Reproducer log entry: Jun 19 12:00:55 piorun kernel: [4475115.459952] audit: type=1400 audit(1434708055.676:19629): apparmor="ALLOWED" operation="file_perm" profile="/usr/sbin/apache2" pid=3512 comm="apache2" laddr=::ffff:193.0.236.159 lport=80 faddr=::ffff:192.168.103.80 fport=61985 family="inet6" sock_type="stream" protocol=6 This patch changes logparser.py to ignore those events. References: https://bugs.launchpad.net/apparmor/+bug/1466812/ I propose this patch for trunk and 2.9.
