Subject: [PATCH net-next 00/19] Netfilter/IPVS updates for net-next

This is a v2 pull request.

Hi,

The following patchset contains Netfilter updates for net-next:

1) Reduce jumpstack footprint: Stash chain in last rule marker in blob for
   tracing. Remove last rule and chain from jumpstack. From Florian Westphal.

2) nf_tables validates all tables before committing the new rules.
   Unfortunately, this has two drawbacks:

   - Since addition of the transaction mutex pernet state gets written to
     outside of the locked section from the cleanup callback, this is
     wrong so do this cleanup directly after table has passed all checks.

   - Revalidate tables that saw no changes. This can be avoided by
     keeping the validation state per table, not per netns.

   From Florian Westphal.

3) Get rid of a few redundant pointers in the traceinfo structure.
   The three removed pointers are used in the expression evaluation loop,
   so gcc keeps them in registers. Passing them to the (inlined) helpers
   thus doesn't increase nft_do_chain text size, while stack is reduced
   by another 24 bytes on 64bit arches. From Florian Westphal.

4) IPVS cleanups in several ways without implementing any functional
   changes, aside from removing some debugging output:

   - Update width of source for ip_vs_sync_conn_options
     The operation is safe, use an annotation to describe it properly.

   - Consistently use array_size() in ip_vs_conn_init()
     It seems better to use helpers consistently.

   - Remove {Enter,Leave}Function. These seem to be well past their
     use-by date.

   - Correct spelling in comments.

   From Simon Horman.

5) Extended netlink error report for netdevice in flowtables and
   netdev/chains. Allow for incrementally add/delete devices to netdev
   basechain. Allow to create netdev chain without device.
