From cf2c008865ae7d62d28e3d63f14935f19a4cb6f5 Mon Sep 17 00:00:00 2001 From: Joy Latten Date: Tue, 20 Mar 2007 23:19:34 +0100 Subject: [XFRM]: Fix missing protocol comparison of larval SAs. I noticed that in xfrm_state_add we look for the larval SA in a few places without checking for protocol match. So when using both AH and ESP, whichever one gets added first, deletes the larval SA. It seems AH always gets added first and ESP is always the larval SA's protocol since the xfrm->tmpl has it first. Thus causing the additional km_query() Adding the check eliminates accidental double SA creation. Signed-off-by: Joy Latten Signed-off-by: David S.
