Hi Mimi,

ima_initialized is being set in ima_init(), before a custom policy is
loaded.  I would think that is too early.  ima_update_policy() is
called after loading a custom policy.  Please see how to detect when a
custom policy is loaded.

ima_init_policy() is called before ima_initialized flag is set.

As far as I understand ima_init_policy() loads custom policies as well. So custom policies (such as arch specific policies, secure boot policies, etc.) are loaded before the queued keys are processed.

But if CONFIG_IMA_WRITE_POLICY is enabled, the policy can be updated anytime. This scenario is not handled in my implementation.

Please correct me if my understanding is wrong.
