From f59bbdfa5c6e2a2f74f0e03d1beab6ddb9b3d466 Mon Sep 17 00:00:00 2001 From: Fan Du Date: Fri, 27 Sep 2013 16:32:50 +0800 Subject: [PATCH] xfrm: Simplify SA looking up when using wildcard source __xfrm4/6_state_addr_check is a four steps check, all we need to do is checking whether the destination address match when looking SA using wildcard source address. Passing saddr from flow is worst option, as the checking needs to reach the fourth step while actually only one time checking will do the work. So, simplify this process by only checking destination address when using wildcard source address for looking up SAs.
