====================
Netfilter/IPVS/OVS updates for net-next

The following patchset contains Netfilter/IPVS fixes and OVS NAT
support, more specifically this batch is composed of:

1) Fix a crash in ipset when performing a parallel flush/dump with
   set:list type, from Jozsef Kadlecsik.

2) Make sure NFACCT_FILTER_* netlink attributes are in place before
   accessing them, from Phil Turnbull.

3) Check return error code from ip_vs_fill_iph_skb_off() in IPVS SIP
   helper, from Arnd Bergmann.

4) Add workaround to IPVS to reschedule existing connections to new
   destination server by dropping the packet and wait for retransmission
   of TCP syn packet, from Julian Anastasov.

5) Allow connection rescheduling in IPVS when in CLOSE state, also
   from Julian.

6) Fix wrong offset of SIP Call-ID in IPVS helper, from Marco Angaroni.

7) Validate IPSET_ATTR_ETHER netlink attribute length, from Jozsef.

8) Check match/targetinfo netlink attribute size in nft_compat,
   patch from Florian Westphal.

9) Check for integer overflow on 32-bit systems in x_tables, from
   Florian Westphal.

Several patches from Jarno Rajahalme to prepare the introduction of
NAT support to OVS based on the Netfilter infrastructure:

10) Schedule IP_CT_NEW_REPLY definition for removal in
    nf_conntrack_common.h.

11) Simplify checksumming recalculation in nf_nat.

12) Add comments to the openvswitch conntrack code, from Jarno.

13) Update the CT state key only after successful nf_conntrack_in()
    invocation.

14) Find existing conntrack entry after upcall.

15) Handle NF_REPEAT case due to templates in nf_conntrack_in().

16) Call the conntrack helper functions once the conntrack has been
    confirmed.

17) And finally, add the NAT interface to OVS.

The batch closes with:

18) Cleanup to use spin_unlock_wait() instead of
    spin_lock()/spin_unlock(), from Nicholas Mc Guire.
