   * The regression tests were fixed for this kernel change but they were fixed
     in a way that always assumed that kernel change is present. They should 
have
     been adjusted so that they act differently according to whether or not the
     kernel change is present (it is a change that could end up being backported
     through the stable trees).

  [Test Case]

   $ sudo apt-get install libapparmor-dev
   $ cd tests/regression/apparmor
   $ make USE_SYSTEM=1
   $ sudo bash exec_stack.sh

   The previous command should result in no output and return value of
  0.

   * This is an extremely low risk change since it only touches regression
     testing code that is not user-facing.

  With the recent upstream commit
  9f834ec18defc369d73ccf9e87a2790bfa05bf46 the cred used for the mmap
  changed resulting in test failures. The tests have been patched for

This bug was fixed in the package apparmor - 2.10.95-0ubuntu2.5

apparmor (2.10.95-0ubuntu2.5) xenial; urgency=medium

  * debian/lib/apparmor/functions, debian/apparmor.init,
debian/apparmor.service, debian/apparmor.upstart,
debian/lib/apparmor/profile-load: Adjust the checks that previously kept
AppArmor policy from being loaded while booting a container. Now we
attempt to load policy if we're in a LXD or LXC managed container that is
using profile stacking inside of a policy namespace. (LP: #1628285)
  * Fix regression tests for stacking so that the kernel SRU process is not
interrupted by failing tests whenever the AppArmor stacking features are
backported from the 16.10 kernel or when the 16.04 LTS Enablement Stack
receives a 4.8 or newer kernel
- debian/patches/r3509-tests-fix-exec_stack-errors-1.patch: Fix the
  exec_stack.sh test when running on 4.8 or newer kernels (LP: #1628745)
- debian/patches/r3558-tests-fix-exec_stack-errors-2.patch: Adjust the
  exec_stack.sh fix mentioned above to more accurately test kernels older
  than 4.8 (LP: #1630069)
- debian/patches/allow-stacking-tests-to-use-system.patch: Apply this
  patch earlier in the series, as to match when it was committed upstream,
  so that the above two patches can be cherry-picked from lp:apparmor

[Kernel-packages] [Bug 1630069] Re: Regression tests can not detect binfmt_elf mmpa semantic change

[Tyler Hicks]

I've completed the AppArmor test plan:

  https://wiki.ubuntu.com/Process/Merges/TestPlans/AppArmor

I've also manually verified the AppArmor portion of this SRU with the
kernel currently in xenial-updates (4.4.0-45.66) and the kernel in
xenial-proposed (4.4.0-46.67), which contains a number of AppArmor
changes.

[Kernel-packages] [Bug 1630069] Re: Regression tests can not detect binfmt_elf mmpa semantic change

[Martin Pitt]

Hello John, or anyone else affected,

Accepted apparmor into xenial-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/apparmor/2.10.95-0ubuntu2.5 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

  [Impact]

   * The exec_stack.sh regression test fails due to a behavior change in 4.8
 kernels from this patch:

 commit 9f834ec18defc369d73ccf9e87a2790bfa05bf46
 Author: Linus Torvalds 
 Date: Mon Aug 22 16:41:46 2016 -0700

 binfmt_elf: switch to new creds when switching to new mm

   * The regression tests were fixed for this kernel change but they were fixed
 in a way that always assumed that kernel change is present. They should 
have
 been adjusted so that they act differently according to whether or not the
 kernel change is present (it is a change that could end up being backported
 through the stable trees).

  [Test Case]

   $ apt-get source apparmor
   $ cd tests/regression/apparmor
   $ make USE_SYSTEM=1
   $ sudo bash exec_stack.sh

   The previous command should result in no output and return value of
  0.

  [Regression Potential]

   * This is an extremely low risk change since it only touches regression
 testing code that is not user-facing.

  [Other]

   * Fixed in upstream lp:apparmor tree:

  == Original description ==

  The regression tests are currently hard coded to the semantics of mmap
  in binfmt_elf

  With the recent upstream commit
  9f834ec18defc369d73ccf9e87a2790bfa05bf46 the cred used for the mmap
  changed resulting in test failures. The tests have been patched for
  this change but it results in the test breaking for everyone using
  upstream releases against pre 4.8 kernels.
