Pablo Neira Ayuso says: ==================== Netfilter fixes for net 1) Fix bogus compilter warning in nfnetlink_queue, from Florian Westphal. 2) Don't run conntrack on vrf with !dflt qdisc, from Nicolas Dichtel. 3) Fix nft_pipapo bucket load in AVX2 lookup routine for six 8-bit groups, from Stefano Brivio. 4) Break rule evaluation on malformed TCP options. 5) Use socat instead of nc in selftests/netfilter/nft_zones_many.sh, also from Florian 6) Fix KCSAN data-race in conntrack timeout updates, from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf: netfilter: conntrack: annotate data-races around ct->timeout selftests: netfilter: switch zone stress to socat netfilter: nft_exthdr: break evaluation if setting TCP option fails selftests: netfilter: Add correctness test for mac,net set type nft_set_pipapo: Fix bucket load in AVX2 lookup routine for six 8-bit groups vrf: don't run conntrack on vrf with !dflt qdisc netfilter: nfnetlink_queue: silence bogus compiler warning ==================== Link: https://lore.kernel.org/r/20211209000847.102598-1-pablo@netfilter.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
