We have experienced occasional bugs in the lunar kernel (specifically with the environ.sh test) that can lead to system crashes / failures (such as potential NULL pointer dereference). [Test case] Run AppArmor autopkgtest / qa-regression-testing. [Fix] Apply the following additional fixes provided by AppArmor upstream maintainer: UBUNTU: SAUCE: apparmor: fix policy_compat perms remap for file dfa UBUNTU: SAUCE: apparmor: fix profile verification and enable it UBUNTU: SAUCE: apparmor: fix: add missing failure check in compute_xmatch_perms UBUNTU: SAUCE: apparmor: fix: kzalloc perms tables for shared dfas [Regression potential] Additional fixes are touching only AppArmor specific code, so we may experience regressions (bugs / behavior change) only in apparmor by applying them.
