Netfilter updates for net-next

The following batch contains netfilter updates for net-next. Basically,
enhancements for xt_recent, skip zeroing of timer in conntrack, fix
linking problem with recent redirect support for nf_tables, ipset
updates and a couple of cleanups. More specifically, they are:

1) Rise maximum number per IP address to be remembered in xt_recent
   while retaining backward compatibility, from Florian Westphal.

2) Skip zeroing timer area in nf_conn objects, also from Florian.

3) Inspect IPv4 and IPv6 traffic from the bridge to allow filtering using
   using meta l4proto and transport layer header, from Alvaro Neira.

4) Fix linking problems in the new redirect support when CONFIG_IPV6=n
   and IP6_NF_IPTABLES=n.

And ipset updates from Jozsef Kadlecsik:

5) Support updating element extensions when the set is full (fixes
   netfilter bugzilla id 880).

6) Fix set match with 32-bits userspace / 64-bits kernel.

7) Indicate explicitly when /0 networks are supported in ipset.

8) Simplify cidr handling for hash:*net* types.

9) Allocate the proper size of memory when /0 networks are supported.

10) Explicitly add padding elements to hash:net,net and hash:net,port,
    because the elements must be u32 sized for the used hash function.

Jozsef is also cooking ipset RCU conversion which should land soon if
they reach the merge window in time.

bridge: add API to notify bridge driver of learned FBD on offloaded device 2014-12-03T04:01:22+00:00 Scott Feldman sfeldma@gmail.com 2014-11-28T13:34:21+00:00 cf6b8e1eedffd9ef9a22c0c9453d752b07daf89a When the swdev device learns a new mac/vlan on a port, it sends some async notification to the driver and the driver installs an FDB in the device. To give a holistic system view, the learned mac/vlan should be reflected in the bridge's FBD table, so the user, using normal iproute2 cmds, can view what is currently learned by the device. This API on the bridge driver gives a way for the swdev driver to install an FBD entry in the bridge FBD table. (And remove one). This is equivalent to the device running these cmds: bridge fdb [add|del] <mac> dev <dev> vid <vlan id> master This patch needs some extra eyeballs for review, in paricular around the locking and contexts.
