Subject: [PATCH net-2.6 3/4] xfrm: Check for the new replay implementation if an esn state is inserted
Date: Tue, 26 Apr 2011 07:41:21 +0200 [thread overview]
Message-ID: <20110426054121.GH5495@secunet.com> (raw)
In-Reply-To: <20110426053923.GF5495@secunet.com>
IPsec extended sequence numbers can be used only with the new
anti-replay window implementation. So check if the new implementation
is used if an esn state is inserted and return an error if it is not.
