Title:
  unix_socket_pathname.sh confined server stream/seqpacket missing
  getopt test fails

Status in AppArmor Linux application security framework:
  Fix Committed
Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  The AF_UNIX pathname stream and seqpacket tests are not failing when
  the server program is missing the getopt unix permission. Note that
  the dgram version of this test fails as expected. This suggests some
  type of difference in the mediation of getsockopt() between connected
  and connectionless sockets.

  Note that you need a branch of lp:apparmor at r2715 or newer to
  reproduce this failure.

  * The test failures:

  Error: unix_socket passed. Test 'AF_UNIX pathname socket (stream);
  confined server w/ a missing af_unix access (getopt)' was expected to
  'fail'

  Error: unix_socket passed. Test 'AF_UNIX pathname socket (seqpacket);
  confined server w/ a missing af_unix access (getopt)' was expected to
  'fail'

  * The profile (note the missing getopt permission):

  /home/tyhicks/apparmor.git/tests/regression/apparmor/unix_socket {
    /etc/ld.so.cache r,
    /proc/*/attr/current w,
    /dev/urandom r,
    /home/tyhicks/apparmor.git/tests/regression/apparmor/unix_socket rix,
    /lib/x86_64-linux-gnu/libpthread-2.19.so mr,
    /lib/x86_64-linux-gnu/libc-2.19.so mr,
    /lib/x86_64-linux-gnu/ld-2.19.so rix,
    /tmp/sdtest.18777-31595-M5yfgv/output.unix_socket w,
    /tmp/sdtest.18777-31595-M5yfgv/aa_sock rw,
    unix (create,,setopt),
    /home/tyhicks/apparmor.git/tests/regression/apparmor/unix_socket_client Ux,
  }

  I've attached the strace output of the test run to show that the
  unix_socket program does successfully call getsockopt().
