Hi David,
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.
