[PATCH 0/7] Netfilter fixes for net

[Pablo Neira Ayuso <pablo@netfilter.org>]

Hi,

The following patchset contains Netfilter fixes for net:

1) A new selftest for nf_queue, from Florian Westphal. This test
   covers two recent fixes: 07f8e4d0fddb ("tcp: also NULL skb->dev
   when copy was needed") and b738a185beaa ("tcp: ensure skb->dev is
   NULL before leaving TCP stack").

2) The fwd action breaks with ifb. For safety in next extensions,
   make sure the fwd action only runs from ingress until it is extended
   to be used from a different hook.

3) The pipapo set type now reports EEXIST in case of subrange overlaps.
   Update the rbtree set to validate range overlaps, so far this
   validation is only done only from userspace. From Stefano Brivio.
