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

The following patchset contains Netfilter fixes for net:

1) refcount_inc_not_zero() is not semantically equivalent to
   atomic_int_not_zero(), from Florian Westphal. My understanding was
   that refcount_*() API provides a wrapper to easier debugging of
   reference count leaks, however, there are semantic differences
   between these two APIs, where refcount_inc_not_zero() needs a barrier.
   Reason for this subtle difference to me is unknown.

2) packet logging is not correct for ARP and IP packets, from the
   ARP family and netdev/egress respectively. Use skb_network_offset()
   to reach the headers accordingly.

3) set element extension length have been growing over time, replace
   a BUG_ON by EINVAL which might be triggerable from userspace.
