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.
====================
