[PATCH 2/6] netfilter: nfnetlink: use original skbuff when acking batches

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2016-02-16 17:04:17
Also in: netfilter-devel
Subsystem: netfilter, networking [general], the rest · Maintainers: Pablo Neira Ayuso, Florian Westphal, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds 

Since bd678e09dc17 ("netfilter: nfnetlink: fix splat due to incorrect
socket memory accounting in skbuff clones"), we don't manually attach
the sk to the skbuff clone anymore, so we have to use the original
skbuff from netlink_ack() which needs to access the sk pointer.

Fixes: bd678e09dc17 ("netfilter: nfnetlink: fix splat due to incorrect socket memory accounting in skbuff clones")
