Bug description:
  [Impact]

   * Users may encounter situations where they use applications, confined by
     AppArmor, that hit EACESS failures when attempting to operate on AF_UNIX
     stream sockets.

   * These failures typically occur when the confined applications attempts to
     read from an AF_UNIX stream socket when the other end of the socket has
     already been closed.

   * AppArmor is mistakenly denying the socket operations due to the socket
     shutdown operation making the sun_path no longer being available for
     AppArmor mediation after the socket is shutdown.

  [Test Case]

   The expected test case is:

   $ sudo apt-get install postfix # installing in 'local only' config is fine
   $ cat > bug-profile << EOF
   profile bug-profile flags=(attach_disconnected) {
     network,
     file,
   }
   EOF
   $ sudo apparmor_parser -r bug.profile 
   $ aa-exec -p bug-profile -- mailq
   Mail queue is empty

   A failed test case will see the mailq command exit with an error:

   $ aa-exec -p bug-profile -- mailq
   postqueue: warning: close: Permission denied

   and these denials will be found in the syslog:

   Jan 25 16:56:29 sec-vivid-amd64 kernel: [  241.096175] audit: type=1400 audit(1453762589.727:30): apparmor="DENIED" operation="file_perm" profile="bug-profile" name="public/showq" pid=4923 comm="postqueue" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0

  [Regression Potential]

   * The changes are local to the path-based AF_UNIX stream socket mediation code
     so that limits the regression potential to some degree.

   * John Johansen authored the patch and I reviewed it. It is small and there's
     no obvious areas of concern to me regarding potential regressions.

  [Other Info]

   * None at this time

  [Original bug report]

  Hello,

  on three Vivid host, all of them up-to-date, I have the problem
  described here:

  https://bugs.launchpad.net/ubuntu/utopic/+source/linux/+bug/1390223

  That bug report shows the problem was fixed, but it is not (at least
  on current Vivid)

  ii  linux-image-generic 3.19.0.15.14   amd64          Generic Linux kernel image

  ii  apparmor            2.9.1-0ubuntu9 amd64          User-space parser utility for AppArmor

  Reproducible with:

  $ sudo lxc-create -n test -t ubuntu
  $ sudo lxc-start -n test

  (inside container)

  $ sudo apt-get install postfix
  $ mailq
  postqueue: warning: close: Permission denied
