Date: Fri, 31 May 2013 03:27:55 +0200 From: Matthias Schiffer <mschiffer@...verse-factory.net> To: davem@...emloft.net, kuznet@....inr.ac.ru, jmorris@...ei.org, yoshfuji@...ux-ipv6.org, kaber@...sh.net Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH net/3.9] ipv6: ndisc: fix ndisc_send_redirect writing to the wrong skb Since some refactoring in 5f5a011, ndisc_send_redirect called ndisc_fill_redirect_hdr_option on the wrong skb, leading to data corruption or in the worst case a panic when the skb_put failed.
