Merge branch 'master' of git://1984.lsi.us.es/nf
Pablo Neira Ayuso says: ==================== The following patchset contains netfilter updates for your net tree, they are: * Fix missing the skb->trace reset in nf_reset, noticed by Gao Feng while using the TRACE target with several net namespaces. * Fix prefix translation in IPv6 NPT if non-multiple of 32 prefixes are used, from Matthias Schiffer. * Fix invalid nfacct objects with empty name, they are now rejected with -EINVAL, spotted by Michael Zintakis, patch from myself. * A couple of fixes for wrong return values in the error path of nfnetlink_queue and nf_conntrack, from Wei Yongjun. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
