Subject: [PATCH net-next v1] tipc: make sure IPv6 header fits in skb headroom
Date: Mon, 14 Mar 2016 09:43:52 +0100 [thread overview]
Message-ID: <1457945032-30547-1-git-send-email-richard.alpe@ericsson.com> (raw)
Expand headroom further in order to be able to fit the larger IPv6
header. Prior to this patch this caused a skb under panic for certain
tipc packets when using IPv6 UDP bearer(s).
