Title:
  aa-logprof crash on #include <directory>

Status in AppArmor Linux application security framework:
  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):
    File "aa-logprof", line 54, in <module>
      apparmor.do_logprof_pass(logmark)
    File "/home/cb/apparmor/2.9-branch/utils/apparmor/aa.py", line 2297, in do_logprof_pass
      collapse_log()
    File "/home/cb/apparmor/2.9-branch/utils/apparmor/aa.py", line 2533, in collapse_log
      if not profile_known_network(aa[profile][hat], family, sock_type):
    File "/home/cb/apparmor/2.9-branch/utils/apparmor/aa.py", line 4394, in profile_known_network
      if netrules_access_check(include[incname][incname]['deny']['netdomain'], family, sock_type):
  KeyError: 'apache2.d'

  
  trunk crash:

  # aa-logprof -f /tmp/syslog
  Lese Logeinträge von /tmp/syslog.
  Aktualisiere AppArmor-Profile in /etc/apparmor.d.
  Traceback (most recent call last):
    File "aa-logprof", line 50, in <module>
      apparmor.do_logprof_pass(logmark)
    File "/home/cb/apparmor/HEAD-clean/utils/apparmor/aa.py", line 2189, in do_logprof_pass
      collapse_log()
    File "/home/cb/apparmor/HEAD-clean/utils/apparmor/aa.py", line 2426, in collapse_log
      if not is_known_rule(aa[profile][hat], 'network', NetworkRule(family, sock_type)):
    File "/home/cb/apparmor/HEAD-clean/utils/apparmor/aa.py", line 4099, in is_known_rule
      if include[incname][incname].get(rule_type, False):
  KeyError: 'apache2.d'

  
  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.
