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

The following patchset contains Netfilter fixes for net:

1) Fix esoteric undefined behaviour due to uninitialized stack access
   in ip_vs_protocol_init(), from Jinghao Jia.

2) Fix iptables xt_LED slab-out-of-bounds due to incorrect sanitization
   of the led string identifier, reported by syzbot. Patch from
   Dmitry Antipov.

3) Remove WARN_ON_ONCE reachable from userspace to check for the maximum
   cgroup level, nft_socket cgroup matching is restricted to 255 levels,
   but cgroups allow for INT_MAX levels by default. Reported by syzbot.

4) Fix nft_inner incorrect use of percpu area to store tunnel parser
   context with softirqs, resulting in inconsistent inner header
   offsets that could lead to bogus rule mismatches, reported by syzbot.

5) Grab module reference on ipset core while requesting set type modules,
   otherwise kernel crash is possible by removing ipset core module,
   patch from Phil Sutter.

6) Fix possible double-free in nft_hash garbage collector due to unstable
   walk interator that can provide twice the same element. Use a sequence
   number to skip expired/dead elements that have been already scheduled
   for removal. Based on patch from Laurent Fasnach
