Subject: [PATCH net 00/15] Netfilter/IPVS fixes for net

Hi,

The following patchset contains Netfilter/IPVS fixes for net:

1) ipset limits the max allocatable memory via kvmalloc() to MAX_INT,
   from Jozsef Kadlecsik.

2) Check ip_vs_conn_tab_bits value to be in the range specified
   in Kconfig, from Andrea Claudi.

3) Initialize fragment offset in ip6tables, from Jeremy Sowden.

4) Make conntrack hash chain length random, from Florian Westphal.

5) Add zone ID to conntrack and NAT hashtuple again, also from Florian.

6) Add selftests for bidirectional zone support and colliding tuples,
   from Florian Westphal.

7) Unlink table before synchronize_rcu when cleaning tables with
   owner, from Florian.

8) ipset limits the max allocatable memory via kvmalloc() to MAX_INT.

9) Release conntrack entries via workqueue in masquerade, from Florian.

10) Fix bogus net_init in iptables raw table definition, also from Florian.

11) Work around missing softdep in log extensions, from Florian Westphal.

12) Serialize hash resizes and cleanups with mutex, from Eric Dumazet.
