[Steve Beattie <sbeattie@xxxxxxxxxx>]

My apologies, I neglected to include this bug report in the changelog
for my apparmor trusty SRU. It has ben accepted into trusty-proposed and
is available at
https://launchpad.net/ubuntu/+source/apparmor/2.8.95~2430-0ubuntu5.2 as
well as from the trusty-proposed repository.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.

The relevant part of the SRU for this bug report is the update to the
upstream apparmor 2.9.2 version of the python utils. This is being
tracked in bug 1449769; please leave feedback on this update in that bug
report. Thanks for your patience!

  [SRU justification]

  [Impact]

  $ sudo aa-complain /etc/apparmor.d/usr.lib.postfix.*
  Setting /etc/apparmor.d/usr.lib.postfix.anvil to complain mode.

  $ sudo grep -R TFTP_DIR /etc/apparmor.d/
  /etc/apparmor.d/usr.sbin.dnsmasq:@{TFTP_DIR}=/var/tftp /srv/tftpboot
  /etc/apparmor.d/usr.sbin.dnsmasq:  @{TFTP_DIR}/ r,
  /etc/apparmor.d/usr.sbin.dnsmasq:  @{TFTP_DIR}/** r,

  Looks like the tools are re-parsing everything, but not resetting
  whatever is storing the variable declarations.

  [Test Case]

  sudo aa-enforce /etc/apparmor.d/*

  got error
