Merge branch 'next-integrity.defer-measuring-keys' into next-integrity
From patch set cover letter: The IMA subsystem supports measuring asymmetric keys when the key is created or updated[1]. But keys created or updated before a custom IMA policy is loaded are currently not measured. This includes keys added, for instance, to either the .ima or .builtin_trusted_keys keyrings, which happens early in the boot process. Measuring the early boot keys, by design, requires loading a custom IMA policy. This change adds support for queuing keys created or updated before a custom IMA policy is loaded. The queued keys are processed when a custom policy is loaded. Keys created or updated after a custom policy is loaded are measured immediately (not queued). In the case when a custom policy is not loaded within 5 minutes of IMA initialization, the queued keys are freed. [1]
