Similar to the change you'd suggested for validating LSM_STATE and
LSM_POLICY func, I think IMA_QUEUE_EARLY_BOOT_DATA config should be
enabled for SECURITY_SELINUX.
depends on SECURITY_SELINUX ||
(IMA_MEASURE_ASYMMETRIC_KEYS && SYSTEM_TRUSTED_KEYRING)
And, when more security modules are added update this CONFIG as appropriate.
Does that sound okay?
