Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Revalidate bridge ports, add missing NULL checks to fetch the bridge
device by the port. From Florian Westphal.
2) Fix netdevice refcount leak in the error path of nft_fwd hardware
offload function, also from Florian.
3) Unregister helper expectfn callback on conntrack helper module
removal, otherwise dangling pointer remains in place,
from Weiming Shi.
4) Fix possible pointer infoleak in getsockopt() IPT_SO_GET_ENTRIES,
From Kyle Zeng.
5) Validate that device MAC header is present before nf_syslog
accesses it. From Xiang Mei.
6-8) Three patches to address a possible infoleak of stale stack
data in three nf_tables expressions, due to mismatch in the
_init() and _eval() function which is possible since 14fb07130c.
From Davide Ornaghi and Florian Westphal.
