====================
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.
