[PATCH 00/12] netfilter/IPVS updates for net-next

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

Hi David,

The following patchset contains Netfilter updates for your net-next tree,
they are:

* Add full port randomization support. Some crazy researchers found a way
  to reconstruct the secure ephemeral ports that are allocated in random mode
  by sending off-path bursts of UDP packets to overrun the socket buffer of
  the DNS resolver to trigger retransmissions, then if the timing for the
  DNS resolution done by a client is larger than usual, then they conclude
  that the port that received the burst of UDP packets is the one that was
  opened. It seems a bit aggressive method to me but it seems to work for
  them. As a result, Daniel Borkmann and Hannes Frederic Sowa came up with a
  new NAT mode to fully randomize ports using prandom.

* Add a new classifier to x_tables based on the socket net_cls set via
  cgroups. These includes two patches to prepare the field as requested by
  Zefan Li. Also from Daniel Borkmann.

* Use prandom instead of get_random_bytes in several locations of the
  netfilter code, from Florian Westphal.

* Allow to use the CTA_MARK_MASK in ctnetlink when mangling the conntrack
  mark, also from Florian Westphal.

* Fix compilation warning due to unused variable in IPVS, from Geert
  Uytterhoeven.

* Add support for UID/GID via nfnetlink_queue, from Valentina Giusti.

* Add IPComp extension to x_tables, from Fan Du.
