Merge git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf
Pablo Neira Ayuso says:
====================
Netfilter fixes for net
1) Protect nft_ct template with global mutex, from Pavel Skripkin.
2) Two recent commits switched inet rt and nexthop exception hashes
from jhash to siphash. If those two spots are problematic then
conntrack is affected as well, so switch voer to siphash too.
While at it, add a hard upper limit on chain lengths and reject
insertion if this is hit. Patches from Florian Westphal.
3) Fix use-after-scope in nf_socket_ipv6 reported by KASAN,
from Benjamin Hesmans.
