Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf 



Pablo Neira Ayuso says:

====================
The following patchset contains three Netfilter fixes and update
for the MAINTAINER file for your net tree, they are:

* Fix crash if nf_log_packet is called from conntrack, in that case
  both interfaces are NULL, from Hans Schillstrom. This bug introduced
  with the logging netns support in the previous merge window.

* Fix compilation of nf_log and nf_queue without CONFIG_PROC_FS,
  from myself. This bug was introduced in the previous merge window
  with the new netns support for the netfilter logging infrastructure.

* Fix possible crash in xt_TCPOPTSTRIP due to missing sanity
  checkings to validate that the TCP header is well-formed, from
  myself. I can find this bug in 2.6.25, probably it's been there
  since the beginning. I'll pass this to -stable.

* Update MAINTAINER file to point to new nf trees at git.kernel.org,
  remove Harald and use M: instead of P: (now obsolete tag) to
  keep Jozsef in the list of people.

Please, consider pulling this. Thanks!
