[ Test Plan ]

This has been extensively tested via the AppArmor regression test
script in the QA Regression Testing repo:
https://git.launchpad.net/qa-regression-testing/tree/scripts/test-apparmor.py

This script runs various tests against the installed apparmor
package, as well as building and running the various upstream
regression and other test suites against this installed package:
  - https://gitlab.com/apparmor/apparmor/-/tree/master/tests/regression/apparmor?ref_type=heads
  - https://gitlab.com/apparmor/apparmor/-/tree/master/utils/test?ref_type=heads
  - https://gitlab.com/apparmor/apparmor/-/tree/master/parser/tst?ref_type=heads
  - https://gitlab.com/apparmor/apparmor/-/tree/master/libraries/libapparmor/testsuite?ref_type=heads

[ Where problems could occur ]

There could still be more applications affected by the
restriction of the creation of unpriviliged user namespaces. They
might require the creation of new unconfined profiles which could
be mitigated in a later SRU.
