===================
Netfilter updates for net-next

The following batch contains Netfilter updates for net-next, they are:

1) Move nft_expr_clone() to nft_dynset, from Paul Gortmaker.

2) Do not include module.h from net/netfilter/nf_tables.h,
   also from Paul.

3) Restrict conntrack sysctl entries to boolean, from Tonghao Zhang.

4) Several patches to add infrastructure to autoload NAT helper
   modules from their respective conntrack helper, this also includes
   the first client of this code in OVS, patches from Flavio Leitner.

5) Add support to match for conntrack ID, from Brett Mastbergen.

6) Spelling fix in connlabel, from Colin Ian King.

7) Use struct_size() from hashlimit, from Gustavo A. R. Silva.

8) Add optimized version of nf_inet_addr_mask(), from Li RongQing.

openvswitch: check for null pointer return from nla_nest_start_noflag

2019-05-05T07:52:07+00:00

The call to nla_nest_start_noflag can return null in the unlikely
event that nla_put returns -EMSGSIZE.  Check for this condition to
avoid a null pointer dereference on pointer nla_reply.

net: openvswitch: return an error instead of doing BUG_ON()

2019-05-04T05:36:36+00:00

For all other error cases in queue_userspace_packet() the error is
returned, so it makes sense to do the same for these two error cases.

openvswitch: load and reference the NAT helper.

2019-04-30T12:19:56+00:00

This improves the original commit 17c357efe5ec ("openvswitch: load
NAT helper") where it unconditionally tries to load the module for
every flow using NAT, so not efficient when loading multiple flows.
It also doesn't hold any references to the NAT module while the
flow is active.

This change fixes those problems. It will try to load the module
only if it's not present. It grabs a reference to the NAT module
and holds it while the flow is active. Finally, an error message
shows up if either actions above fails.
