From fd169f15a67b47f23bd1704919c719a8e8409a73 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 20 Oct 2006 19:44:17 -0700 Subject: [PATCH] [DCCP] ipv6: Fix opt_skb leak. Based upon a patch from Jesper Juhl. Try to match the TCP IPv6 code this was copied from as much as possible, so that it's easy to see where to add the ipv6 pktoptions support code.
