Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf
Pablo Neira Ayuso says:
====================
The following patchset contains Netfilter fixes for your net tree,
they are:
* Fix potential NULL dereference in the socket match if revision 0
is used, from Eric Dumazet.
* Fix missing expectation NAT initialization that results in dumping
the NAT part via ctnetlink, thus leading to problems in expectation
synchronization through conntrackd, from myself.
====================
