Message-Id: <c3215dad8a657aff32ef983ae935e435127d3e48.1259142145.git.martin@strongswan.org> Date: Wed, 25 Nov 2009 11:29:53 +0100 From: Martin Willi <martin@...ongswan.org> To: Herbert Xu <herbert@...dor.apana.org.au> Cc: linux-crypto@...r.kernel.org, netdev@...r.kernel.org Subject: [PATCH 3/3] xfrm: Use the user specified truncation length in ESP and AH Instead of using the hardcoded truncation for authentication algorithms, use the truncation length specified on xfrm_state.
