====================
Netfilter/IPVS fixes for net

The following patchset contains Netfilter updates for your net tree,
they are:

1) Fix missing initialization of the range structure (allocated in the
   stack) in nft_masq_{ipv4, ipv6}_eval, from Daniel Borkmann.

2) Make sure the data we receive from userspace contains the req_version
   structure, otherwise return an error incomplete on truncated input.
   From Dan Carpenter.

3) Fix handling og skb->sk which may cause incorrect handling
   of connections from a local process. Via Simon Horman, patch from
   Calvin Owens.

4) Fix wrong netns in nft_compat when setting target and match params
   structure.

5) Relax chain type validation in nft_compat that was recently included,
   this broke the matches that need to be run from the route chain type.
   Now iptables-test.py automated regression tests report success again
   and we avoid the only possible problematic case, which is the use of
   nat targets out of nat chain type.

6) Use match->table to validate the tablename, instead of the match->name.
   Again patch for nft_compat.

7) Restore the synchronous release of objects from the commit and abort
   path in nf_tables. This is causing two major problems: splats when using
   nft_compat, given that matches and targets may sleep and call_rcu is
   invoked from softirq context. Moreover Patrick reported possible event
   notification reordering when rules refer to anonymous sets.

8) Fix race condition in between packets that are being confirmed by
   conntrack and the ctnetlink flush operation. This happens since the
   removal of the central spinlock. Thanks to Jesper D. Brouer to looking
   into this.
