Florian Westphal says:
====================
Subject: netfilter: updates for net-next
1) Speed up nftables transactions after earlier transaction failed.
Due to a (harmeless) bug we remained in slow paranoia mode until
a successful transaction completes.
2) Allow generic tracker to resolve clashes, this avoids very rare
packet drops. From Yuto Hamaguchi.
3) Increase the cleanup budget to 64 entries in nf_conncount to reap
more entries in one go, from Fernando Fernandez Mancera.
4) Allow icmp trackers to resolve clashes, this avoids very rare
initial packet drop with test cases that have high-frequency pings.
After this all trackers except tcp and sctp allow clash resolution.
5) Disentangle netfilter headers, don't include nftables/xtables headers
in subsystems that are unrelated.
6) Don't rely on implicit includes coming from nf_conntrack_proto_gre.h.
7) Allow nfnetlink_queue nfq instance struct to get accounted via memcg,
from Scott Mitchell.
8) Reject bogus xt target/match data upfront via netlink policiy in
nft_compat interface rather than relying on x_tables API to do it.
9) Fix nf_conncount breakage when trying to limit loopback flows via
prerouting rule, from Fernando Fernandez Mancera.
This is a recent breakage but not seen as urgent enough to rush this
via net tree at this late stage in development cycle.
10) Fix a possible off-by-one when parsing tcp option in xtables tcpmss
match. Also handled via -next due to late stage in development
cycle.
