[RFC PATCH v4 3/5] ima: differentiate auditing policy rules from "audit" actions

From: Stefan Berger
Date: Fri May 11 2018 - 10:43:34 EST


From: Mimi Zohar <zohar@xxxxxxxxxxxxxxxxxx>

The AUDIT_INTEGRITY_RULE is used for auditing IMA policy rules and
the IMA "audit" policy action. This patch defines AUDIT_INTEGRITY_POLICY
to reflect the IMA policy rules.
