====================
Netfilter updates for net-next

The following large patchset contains Netfilter updates for your
net-next tree. My initial intention was to send you this in two goes but
when I looked back twice I already had this burden on top of me.

Several updates for IPVS from Marco Angaroni:

1) Allow SIP connections originating from real-servers to be load
   balanced by the SIP persistence engine as is already implemented
   in the other direction.

2) Release connections immediately for One-packet-scheduling (OPS)
   in IPVS, instead of making it via timer and rcu callback.

3) Skip deleting conntracks for each one packet in OPS, and don't call
   nf_conntrack_alter_reply() since no reply is expected.

4) Enable drop on exhaustion for OPS + SIP persistence.

Miscelaneous conntrack updates from Florian Westphal, including fix for
hash resize:

5) Move conntrack generation counter out of conntrack pernet structure
   since this is only used by the init_ns to allow hash resizing.

6) Use get_random_once() from packet path to collect hash random seed
    instead of our compound.

7) Don't disable BH from ____nf_conntrack_find() for statistics,
   use NF_CT_STAT_INC_ATOMIC() instead.

8) Fix lookup race during conntrack hash resizing.

9) Introduce clash resolution on conntrack insertion for connectionless
   protocol.

Then, Florian's netns rework to get rid of per-netns conntrack table,
thus we use one single table for them all. There was consensus on this
change during the NFWS 2015 and, on top of that, it has recently been
pointed as a source of multiple problems from unpriviledged netns:

11) Use a single conntrack hashtable for all namespaces. Include netns
    in object comparisons and make it part of the hash calculation.
    Adapt early_drop() to consider netns.

12) Use single expectation and NAT hashtable for all namespaces.

13) Use a single slab cache for all namespaces for conntrack objects.

14) Skip full table scanning from nf_ct_iterate_cleanup() if the pernet
    conntrack counter tells us the table is empty (ie. equals zero).

Fixes for nf_tables interval set element handling, support to set
conntrack connlabels and allow set names up to 32 bytes.

15) Parse element flags from element deletion path and pass it up to the
    backend set implementation.

16) Allow adjacent intervals in the rbtree set type for dynamic interval
    updates.

17) Add support to set connlabel from nf_tables, from Florian Westphal.

18) Allow set names up to 32 bytes in nf_tables.

Several x_tables fixes and updates:

19) Fix incorrect use of IS_ERR_VALUE() in x_tables, original patch
    from Andrzej Hajda.

And finally, miscelaneous netfilter updates such as:

20) Disable automatic helper assignment by default. Note this proc knob
    was introduced by a900689264 ("netfilter: nf_ct_helper: allow to
    disable automatic helper assignment") 4 years ago to start moving
    towards explicit conntrack helper configuration via iptables CT
    target.

21) Get rid of obsolete and inconsistent debugging instrumentation
    in x_tables.

22) Remove unnecessary check for null after ip6_route_output().
