1) Fix missing overflow use refcount checks in nf_tables.

2) Do not set IPS_ASSURED for IPS_NAT_CLASH entries in GRE tracker,
   from Florian Westphal.

3) Bail out if nf_ct_helper_hash is NULL before registering helper,
   from Florent Revest.

4) Use siphash() instead siphash_4u64() to fix performance regression,
   also from Florian.

5) Do not allow to add rules to removed chains via ID,
   from Thadeu Lima de Souza Cascardo.

6) Fix oob read access in byteorder expression, also from Thadeu.
