====================
netfilter: updates for net-next

The following patchset contains Netfilter updates for *net-next*:

1) Fix net-next-only use-after-free bug in nf_tables rbtree set:
   Expired elements cannot be released right away after unlink anymore
   because there is no guarantee that the binary-search blob is going to
   be updated.  Spotted by syzkaller.

2) Fix esoteric bug in nf_queue with udp fraglist gro, broken since
   6.11. Patch 3 adds extends the nfqueue selftest for this.

4) Use dedicated slab for flowtable entries, currently the -512 cache
   is used, which is wasteful.  From Qingfang Deng.

5) Recent net-next update extended existing test for ip6ip6 tunnels, add
   the required /config entry.  Test still passed by accident because the
   previous tests network setup gets re-used, so also update the test so
   it will fail in case the ip6ip6 tunnel interface cannot be added.

6) Fix 'nft get element mytable myset { 1.2.3.4 }' on big endian
   platforms, this was broken since code was added in v5.1.

7) Fix nf_tables counter reset support on 32bit platforms, where counter
   reset may cause huge values to appear due to wraparound.
   Broken since reset feature was added in v6.11.  From Anders Grahn.

8-11) update nf_tables rbtree set type to detect partial
   operlaps.  This will eventually speed up nftables userspace: at this
   time userspace does a netlink dump of the set content which slows down
   incremental updates on interval sets.  From Pablo Neira Ayuso.
