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

1) Fix crash with malformed ebtables blob which do not provide all
   entry points, from Florian Westphal.

2) Fix possible TCP connection clogging up with default 5-days
   timeout in conntrack, from Florian.

3) Fix crash in nf_tables tproxy with unsupported chains, also from Florian.

4) Do not allow to update implicit chains.

5) Make table handle allocation per-netns to fix data race.

6) Do not truncated payload length and offset, and checksum offset.
   Instead report EINVAl.

7) Enable chain stats update via static key iff no error occurs.

8) Restrict osf expression to ip, ip6 and inet families.

9) Restrict tunnel expression to netdev family.

10) Fix crash when trying to bind again an already bound chain.

11) Flowtable garbage collector might leave behind pending work to
    delete entries. This patch comes with a previous preparation patch
    as dependency.

12) Allow net.netfilter.nf_conntrack_frag6_high_thresh to be lowered,
    from Eric Dumazet.
