Pablo Neira Ayuso says:

====================
Netfilter fixes for net

1) Don't refresh timeout for SCTP flows in CLOSED state.

2) Don't allow access to transport header if fragment offset is set on.

3) Reinitialize internal conntrack state for retransmitted TCP
   syn-ack packet.

4) Update MAINTAINER file to add the Netfilter group tree. Moving
   forward, Florian Westphal has access to this tree so he can also
   send pull requests.

5) Set on IPS_HELPER for entries created via ctnetlink, otherwise NAT
   might zap it.

All patches from Florian Westphal.
