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

The following patchset contains Netfilter fixes for your net tree:

1) Missing netlink attribute validation in nf_queue, uncovered by KASAN,
   from Eric Dumazet.

2) Use pointer to sysctl table, save us 192 bytes of memory per netns.
   Also from Eric.

3) Possible use-after-free when removing conntrack helper modules due
   to missing synchronize RCU call. From Taehee Yoo.

4) Fix corner case in systcl writes to nf_log that lead to appending
   data to uninitialized buffer, from Jann Horn.

5) Jann Horn says we may indefinitely block other users of nf_log_mutex
   if a userspace access in proc_dostring() blocked e.g. due to a
   userfaultfd.

6) Fix garbage collection race for unconfirmed conntrack entries,
   from Florian Westphal.
