[PATCH net-next 0/6] Netfilter updates for net-next

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

Hi,

The following patchset contains Netfilter updates for net-next:

1) Skip non-SCTP packets in the new SCTP chunk support for nft_exthdr,
   from Phil Sutter.

2) Simplify TCP option sanity check for TCP packets, also from Phil.

3) Add a new expression to store when the rule has been used last time.

4) Pass the hook state object to log function, from Florian Westphal.

5) Document the new sysctl knobs to tune the flowtable timeouts,
   from Oz Shlomo.

6) Fix snprintf error check in the new nfnetlink_hook infrastructure,
   from Dan Carpenter.

Please, pull these changes from:

Thank you!
