+From 738a9857be9c92ad2f70be88ccee238e3154a936 Mon Sep 17 00:00:00 2001
+From: Joe MacDonald <joe.macdonald@windriver.com>
+Date: Wed, 2 Oct 2013 14:20:37 -0400
+Subject: [PATCH] racoon/pfkey: avoid potential null-pointer dereference
+
+Building with -Werror=maybe-uninitialized revealed that 'remote' from
+pk_recvmigrate() could be used with uninitialized data in
+migrate_sp_ike_addresses().  Ensure it is always at a minimum assigned
+NULL.
