[PATCH net 0/7] Netfilter fixes for net

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

Hi,

The following patchset contains Netfilter fixes for net:

1) Fix NAT IPv6 offload in the flowtable.

2) icmpv6 is printed as unknown in /proc/net/nf_conntrack.

3) Use div64_u64() in nft_limit, from Eric Dumazet.

4) Use pre_exit to unregister ebtables and arptables hooks,
   from Florian Westphal.

5) Fix out-of-bound memset in x_tables compat match/target,
   also from Florian.

6) Clone set elements expression to ensure proper initialization.

Please, pull these changes from:

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

Thanks!
