Revision bbd6528d28c1b8e80832b3b018ec402b6f5c3215 authored by Eric Dumazet on 14 September 2018, 19:02:31 UTC, committed by David S. Miller on 17 September 2018, 14:56:02 UTC
In the unlikely case ip6_xmit() has to call skb_realloc_headroom(),
we need to call skb_set_owner_w() before consuming original skb,
otherwise we risk a use-after-free.
Bring IPv6 in line with what we do in IPv4 to fix this.
