[LTP] [PATCH v3 00/10] LTP tests: load predefined policy, enhancements

[Petr Vorel]

Changes v2->v3:
* Rewrite verifying logic if policy needs to be loaded and how it is
  loaded.
* Allow testing when policy is not reliable, but relax failures to TCONF.
* Add TCB policy example.
* Document LTP_IMA_LOAD_POLICY in doc/users/setup_tests.rst.
* Fix test policy installation (previously wrong Makefile).
* Removed some of the previous commits ("ima_kexec.sh: Relax result on
  unreadable policy to TCONF", "ima_violations.sh: Check for a required policy",
  "ima_setup: Print warning when policy not readable").
* More cleanup.

TODO: ima_measurements.sh and ima_violations.sh use detection for
ima_policy=tcb builtin policy. But if example policy is loaded there is
no longer tcb policy. Not sure how to fix it - some tooling might not
support reboot, thus I wanted to use ima_policy=tcb, which previously
worked.

Petr Vorel (10):
  ima_violations.sh: Fix log detection
  IMA: Add TCB policy as an example for ima_measurements.sh
  IMA: Move requirement check to ima_setup.sh
  IMA: Add example policy for ima_violations.sh
  IMA: Read required policy from file
  ima_violations.sh: Declare tcb builtin policy
  ima_setup.sh: Add digest index detection for ima-buf format
  ima_setup.sh: Allow to load predefined policy
  ima_measurements.sh: Check policy for test3
  tst_test.sh: IMA: Allow to disable LSM warnings and use it for IMA
