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

1) Use kfree_rcu(ptr, rcu) variant, using kfree_rcu(ptr) was not
   intentional. From Eric Dumazet.

2) Use-after-free in netfilter hook core, from Eric Dumazet.

3) Missing rcu read lock side for netfilter egress hook,
   from Florian Westphal.

4) nf_queue assume state->sk is full socket while it might not be.
   Invoke sock_gen_put(), from Florian Westphal.

5) Add selftest to exercise the reported KASAN splat in 4)

6) Fix possible use-after-free in nf_queue in case sk_refcnt is 0.
   Also from Florian.

7) Use input interface index only for hardware offload, not for
   the software plane. This breaks tc ct action. Patch from Paul Blakey.
