====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for your net-next
tree, the most relevant things in this batch are:
1) Compile masquerade infrastructure into NAT module, from Florian Westphal.
Same thing with the redirection support.
2) Abort transaction if early initialization of the commit phase fails.
Also from Florian.
3) Get rid of synchronize_rcu() by using rule array in nf_tables, from
Florian.
4) Abort nf_tables batch if fatal signal is pending, from Florian.
5) Use .call_rcu nfnetlink from nf_tables to make dumps fully lockless.
From Florian Westphal.
6) Support to match transparent sockets from nf_tables, from Máté Eckl.
7) Audit support for nf_tables, from Phil Sutter.
8) Validate chain dependencies from commit phase, fall back to fine grain
validation only in case of errors.
9) Attach dst to skbuff from netfilter flowtable packet path, from
Jason A. Donenfeld.
10) Use artificial maximum attribute cap to remove VLA from nfnetlink.
Patch from Kees Cook.
11) Add extension to allow to forward packets through neighbour layer.
12) Add IPv6 conntrack helper support to IPVS, from Julian Anastasov.
13) Add IPv6 FTP conntrack support to IPVS, from Julian Anastasov.
