[v1,0/3] Verify measurement of certificate imported into a keyring

Message

Lachlan Sneff Aug. 3, 2020, 5:59 p.m. UTC

The IMA subsystem supports measuring certificates that have been loaded into
user-defined keyrings and system built-in keyrings. A test to verify that
those measurements are correct is required.

The first two patches in this patchset fix up left-over documentation and
move some datafiles around to prepare for more datafiles in the 3rd patch.

The third patch adds a new test to the `ima_keys.sh` file, which imports
a certificate into a user-defined keyring, and then verifies that the
certificate has been measured correctly by the IMA subsystem.

Lachlan Sneff (3):
  IMA: Update key test documentation
  IMA: Refactor datafiles directory
  IMA: Add a test to verify measurement of certificate imported into a
    keyring
