From de9fbb9b8480bbcde060589621923fceb4b4a5d7 Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Mon, 27 Apr 2009 02:58:59 -0700 Subject: [PATCH] xfrm: wrong hash value for temporary SA [ Upstream commit 6a783c9067e3f71aac61a9262fe42c1f68efd4fc ] When kernel inserts a temporary SA for IKE, it uses the wrong hash value for dst list. Two hash values were calcultated before: one with source address and one with a wildcard source address. Bug hinted by Junwei Zhang Signed-off-by: Nicolas Dichtel Signed-off-by: David S.
