From 436a0a402203d5a47d2edf7e4dde6c08a7257983 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 8 Oct 2007 17:25:53 -0700 Subject: [IPSEC]: Move output replay code into xfrm_output The replay counter is one of only two remaining things in the output code that requires a lock on the xfrm state (the other being the crypto). This patch moves it into the generic xfrm_output so we can remove the lock from the transforms themselves. Signed-off-by: Herbert Xu Signed-off-by: David S.
