Florian Westphal says:

====================
netfilter: updates for net

The following patchset contains Netfilter fixes for *net*:

1) Fix overlap detection for nf_tables with concatenated ranges.
   There are cases where element could not be added due to a conflict
   with existing range, while kernel reports success to userspace.
2) update selftest to cover this bug.
3) synproxy update path should use READ/WRITE once as we replace
   config struct while packet path might read it in parallel.
   This relies on said config struct to fit sizeof(long).
   From Fernando Fernandez Mancera.
4) Don't return -EEXIST from xtables in module load path, a pending
   patch to module infra will spot a warning if this happens.
   From Daniel Gomez.
5) Fix a memory leak in nf_tables when chain hits 2**32 users
   and rule is to be hw-offloaded, from Zilin Guan.
6) Avoid infinite list growth when insert rate is high in nf_conncount,
   also from Fernando.
