From 54489c14c058822f7019648b3718bd3820dee802 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 27 Oct 2006 15:29:47 -0700 Subject: [PATCH] [XFRM] xfrm_user: Fix unaligned accesses. Use memcpy() to move xfrm_address_t objects in and out of netlink messages. The vast majority of xfrm_user was doing this properly, except for copy_from_user_state() and copy_to_user_state().
