====================
netfilter fixes for net
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.
