Subject: [PATCH] Allow AIDE to mmap files
Date: Mon, 25 Feb 2019 23:37:47 +0000
Message-ID: <20190225233708.15319-6-dsugar@tresys.com> (raw)
In-Reply-To: <20190225233708.15319-1-dsugar@tresys.com>

AIDE has a compile time option WITH_MMAP which allows AIDE to
map files during scanning.  RHEL7 has set this option in the
aide rpm they distribute.

Changes made to add a tunable to enable permissions allowing
aide to map files that it needs.  I have set the default to
false as this seems perfered (in my mind).
