====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Don't pick fixed hash implementation for NFT_SET_EVAL sets, otherwise
userspace hits EOPNOTSUPP with valid rules using the meter statement,
from Florian Westphal.
2) If you send a batch that flushes the existing ruleset (that contains
a NAT chain) and the new ruleset definition comes with a new NAT
chain, don't bogusly hit EBUSY. Also from Florian.
3) Missing netlink policy attribute validation, from Florian.
4) Detach conntrack template from skbuff if IP_NODEFRAG is set on,
from Paolo Abeni.
5) Cache device names in flowtable object, otherwise we may end up
walking over devices going aways given no rtnl_lock is held.
6) Fix incorrect net_device ingress with ingress hooks.
7) Fix crash when trying to read more data than available in UDP
packets from the nf_socket infrastructure, from Subash.
