[PATCH 0/7] netfilter fixes for net

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2014-10-20 08:09:17
Also in: netfilter-devel 

Hi David,

The following patchset contains netfilter fixes for your net tree,
they are:

1) Fix missing MODULE_LICENSE() in the new nf_reject_ipv{4,6} modules.

2) Restrict nat and masq expressions to the nat chain type. Otherwise,
   users may crash their kernel if they attach a nat/masq rule to a non
   nat chain.

3) Fix hook validation in nft_compat when non-base chains are used.
   Basically, initialize hook_mask to zero.

4) Make sure you use match/targets in nft_compat from the right chain
   type. The existing validation relies on the table name which can be
   avoided by

5) Better netlink attribute validation in nft_nat. This expression has
   to reject the configuration when no address and proto configurations
   are specified.

6) Interpret NFTA_NAT_REG_*_MAX if only if NFTA_NAT_REG_*_MIN is set.
   Yet another sanity check to reject incorrect configurations from
   userspace.

7) Conditional NAT attribute dumping depending on the existing
   configuration.

Thanks!
