From mboxrd@z Thu Jan 1 00:00:00 1970 From: Martin Willi Subject: [PATCH 0/3] xfrm: Custom truncation lengths for authentication algorithms Date: Wed, 25 Nov 2009 11:29:50 +0100 Message-ID: Cc: linux-crypto@vger.kernel.org, netdev@vger.kernel.org To: Herbert Xu Return-path: Sender: linux-crypto-owner@vger.kernel.org List-Id: netdev.vger.kernel.org The following patchset adds support for defining truncation lengths for authentication algorithms in userspace. The main purpose for this is to support SHA256 in IPsec using the standardized 128 bit instead of the currently used 96 bit truncation. Martin Willi (3): xfrm: Define new XFRM netlink auth attribute with specified truncation bits xfrm: Store aalg in xfrm_state with a user specified truncation length xfrm: Use the user specified truncation length in ESP and AH include/linux/xfrm.h | 8 +++ include/net/xfrm.h | 12 ++++- net/ipv4/ah4.c | 2 +- net/ipv4/esp4.c | 2 +- net/ipv6/ah6.c | 2 +- net/ipv6/esp6.c | 2 +- net/xfrm/xfrm_state.c | 2 +- net/xfrm/xfrm_user.c | 129 ++++++++++++++++++++++++++++++++++++++++++++++--- 8 files changed, 145 insertions(+), 14 deletions(-)
