Subject: [PATCH 0/6] Netfilter fixes for net

Hi David,

The following patchset contains Netfilter fixes for your net tree,
they are:

1) Fix OOM that syskaller triggers with ipt_replace.size = -1 and
   IPT_SO_SET_REPLACE socket option, from Dmitry Vyukov.

2) Check for too long extension name in xt_request_find_{match|target}
   that result in out-of-bound reads, from Eric Dumazet.

3) Fix memory exhaustion bug in ipset hash:*net* types when adding ranges
   that look like x.x.x.x-255.255.255.255, from Jozsef Kadlecsik.

4) Fix pointer leaks to userspace in x_tables, from Dmitry Vyukov.

5) Insufficient sanity checks in clusterip_tg_check(), also from Dmitry.

You can pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf.git

Thanks!

P.S: Another batch is following up soon, there are more fixes cooking on
     the mailing list.
