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 # make sure this fetches the new apparmor source $ 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. [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: https://bazaar.launchpad.net/~apparmor- dev/apparmor/master/revision/3558 == 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.
