Merge branch 'master' of git://1984.lsi.us.es/nf-next
Pablo Neira Ayuso says:
====================
The following patchset contains four Netfilter updates, mostly targeting
to fix issues added with IPv6 NAT, and one little IPVS update for net-next:
* Remove unneeded conditional free of skb in nfnetlink_queue, from
Wei Yongjun.
* One semantic path from coccinelle detected the use of list_del +
INIT_LIST_HEAD, instead of list_del_init, again from Wei Yongjun.
* Fix out-of-bound memory access in the NAT address selection, from
Florian Westphal. This was introduced with the IPv6 NAT patches.
* Two fixes for crashes that were introduced in the recently merged
IPv6 NAT support, from myself.
