====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Use signed integer in ipv6_skip_exthdr() called from nf_confirm().
   Reported by static analysis tooling, patch from Florian Westphal.

2) Missing set type checks in nf_tables: Validate that set declaration
   matches the an existing set type, otherwise bail out with EEXIST.
   Currently, nf_tables silently accepts the re-declaration with a
   different type but it bails out later with EINVAL when the user adds
   entries to the set. This fix is relatively large because it requires
   two preparation patches that are included in this batch.

3) Do not ignore updates of timeout and gc_interval parameters in
   existing sets.

4) Fix a hang when 0/0 subnets is added to a hash:net,port,net type of
   ipset. Except hash:net,port,net and hash:net,iface, the set types don't
   support 0/0 and the auxiliary functions rely on this fact. So 0/0 needs
   a special handling in hash:net,port,net which was missing (hash:net,iface
   was not affected by this bug), from Jozsef Kadlecsik.

5) When adding/deleting large number of elements in one step in ipset,
   it can take a reasonable amount of time and can result in soft lockup
   errors. This patch is a complete rework of the previous version in order
   to use a smaller internal batch limit and at the same time removing
   the external hard limit to add arbitrary number of elements in one step.
   Also from Jozsef Kadlecsik.

Except for patch #1, which fixes a bug introduced in the previous net-next
development cycle, anything else has been broken for several releases.
