Subject: [refpolicy] [PATCH v1 3/9] Introduce dontaudit interfaces for
	leaked fd and unix stream sockets
In-Reply-To: <1353185935-17421-1-git-send-email-sven.vermeulen@siphos.be>
References: <1353185935-17421-1-git-send-email-sven.vermeulen@siphos.be>
Message-ID: <1353185935-17421-4-git-send-email-sven.vermeulen@siphos.be>
To: refpolicy@oss.tresys.com
List-Id: refpolicy.oss.tresys.com

The fail2ban application leaks file descriptors and unix stream sockets when it
invokes sendmail, so introduce the necessary dontaudit interfaces which will be
used in a later patch against the mta and postfix policies.
