calls. Add MAC Framework entry points and MAC policy entry points for audit(), auditctl(), auditon(), setaudit(), aud setauid(). MAC Framework entry points are only added for audit system calls where additional argument context may be useful for policy decision-making; other audit system calls without arguments may be controlled via the priv(9) entry points. Update various policy modules to implement audit-related checks, and in some cases, other missing system-related checks. Obtained from: TrustedBSD Project Sponsored by: SPARTA, Inc.
