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.
