Subject: [refpolicy] [PATCH v2] logging: Various audit tools (auditctl,
	ausearch, etc) map their config and logs
Message-ID: <20170912024046.23186-1-aranea@aixah.de>
To: refpolicy@oss.tresys.com
List-Id: refpolicy.oss.tresys.com

Those mmap() calls are non-essential, though. They're issued by
fdopen(), which can also fall back to read().

Since there are few reasons to grant read access to audit logs other
than for using ausearch, I've added the dontaudits directly to the
relevant read interfaces.
