====================
The following patchset contains three Netfilter fixes, they are:

* Fix conntrack helper re-assignment after NAT mangling if only if
  the same helper is attached to the conntrack again, from Florian
  Westphal.

* Don't allow the creation of conntrack entries via ctnetlink if the
  original and reply tuples are missing, from Florian Westphal.

* Fix broken sysctl interface in nf_ct_reasm while adding netns support
  to it, from Michal Kubecek.
