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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
