Pull networking updates from David Miller:
"Another merge window, another set of networking changes. I've heard
rumblings that the lightweight tunnels infrastructure has been voted
networking change of the year. But what do I know?

1) Add conntrack support to openvswitch, from Joe Stringer.

2) Initial support for VRF (Virtual Routing and Forwarding), which
allows the segmentation of routing paths without using multiple
devices. There are some semantic kinks to work out still, but
this is a reasonably strong foundation. From David Ahern.

3) Remove spinlock fro act_bpf fast path, from Alexei Starovoitov.

4) Ignore route nexthops with a link down state in ipv6, just like
ipv4. From Andy Gospodarek.

5) Remove spinlock from fast path of act_gact and act_mirred, from
Eric Dumazet.

6) Document the DSA layer, from Florian Fainelli.

7) Add netconsole support to bcmgenet, systemport, and DSA. Also
from Florian Fainelli.

8) Add Mellanox Switch Driver and core infrastructure, from Jiri
Pirko.

9) Add support for "light weight tunnels", which allow for
encapsulation and decapsulation without bearing the overhead of a
full blown netdevice. From Thomas Graf, Jiri Benc, and a cast of
others.

10) Add Identifier Locator Addressing support for ipv6, from Tom
Herbert.

11) Support fragmented SKBs in iwlwifi, from Johannes Berg.

12) Allow perf PMUs to be accessed from eBPF programs, from Kaixu Xia.

13) Add BQL support to 3c59x driver, from Loganaden Velvindron.

14) Stop using a zero TX queue length to mean that a device shouldn't
have a qdisc attached, use an explicit flag instead. From Phil
Sutter.

15) Use generic geneve netdevice infrastructure in openvswitch, from
Pravin B Shelar.

16) Add infrastructure to avoid re-forwarding a packet in software
that was already forwarded by a hardware switch. From Scott
Feldman.

17) Allow AF_PACKET fanout function to be implemented in a bpf
program, from Willem de Bruijn"

====================
Geneve: Add support for tunnel metadata mode

Following patches adds support for Geneve tunnel metadata
mode. OVS can make use of Geneve net-device with tunnel
metadata API from kernel.

This also allows us to consolidate Geneve implementation
from two kernel modules geneve_core and geneve to single
geneve module. geneve_core module was targeted to share
Geneve encap and decap code between Geneve netdevice and
OVS Geneve tunnel implementation, Since OVS no longer
needs these API, Geneve code can be consolidated into
single geneve module.

v3-v4:
- Drop NETIF_F_NETNS_LOCAL feature.
- Fix geneve device newlink check

v2-v3:
- make tunnel medata device and regular device mutually exclusive.
- Fix Kconfig dependency for Geneve.
- Fix dst-port netlink encoding.
- drop changelink patch.

v1-v2:
- Replaced per hash table tunnel pointer (metadata enabled) with flag.
- Added support for changelink.
- Improve geneve device route lookup with more parameters.

Joe Stringer says:

====================
OVS conntrack support

The goal of this series is to allow OVS to send packets through the Linux
kernel connection tracker, and subsequently match on fields populated by
conntrack. This functionality is enabled through a new
CONFIG_OPENVSWITCH_CONNTRACK option.

This version addresses the feedback from v5, primarily checking the behaviour
is correct with different configurations such as disabling
CONFIG_OPENVSWITCH_CONNTRACK or disabling individual conntrack features like
connlabels.

The branch below has been updated with the corresponding userspace pieces:

openvswitch: Add conntrack action

Expose the kernel connection tracker via OVS. Userspace components can
make use of the CT action to populate the connection state (ct_state)
field for a flow. This state can be subsequently matched.

Exposed connection states are OVS_CS_F_*:
- NEW (0x01) - Beginning of a new connection.
- ESTABLISHED (0x02) - Part of an existing connection.
- RELATED (0x04) - Related to an established connection.
- INVALID (0x20) - Could not track the connection for this packet.
- REPLY_DIR (0x40) - This packet is in the reply direction for the flow.
- TRACKED (0x80) - This packet has been sent through conntrack.

When the CT action is executed by itself, it will send the packet
through the connection tracker and populate the ct_state field with one
or more of the connection state flags above. The CT action will always
set the TRACKED bit.

When the COMMIT flag is passed to the conntrack action, this specifies
that information about the connection should be stored. This allows
subsequent packets for the same (or related) connections to be
correlated with this connection. Sending subsequent packets for the
connection through conntrack allows the connection tracker to consider
the packets as ESTABLISHED, RELATED, and/or REPLY_DIR.

The CT action may optionally take a zone to track the flow within. This
allows connections with the same 5-tuple to be kept logically separate
from connections in other zones. If the zone is specified, then the
"ct_zone" match field will be subsequently populated with the zone id.

IP fragments are handled by transparently assembling them as part of the
CT action. The maximum received unit (MRU) size is tracked so that
refragmentation can occur during output.

IP frag handling contributed by Andy Zhou.

Based on original design by Justin Pettit.

Merge branch 'lwtunnel'

Thomas Graf says:

====================
Lightweight & flow based encapsulation

This series combines the work previously posted by Roopa, Robert and
myself. It's according to what we discussed at NFWS. The motivation
of this series is to:

* Consolidate code between OVS and the rest of the kernel and get
rid of OVS vports and instead represent them as pure net_devices.
* Introduce a lightweight tunneling mechanism which enables flow
based encapsulation to improve scalability on both RX and TX.
* Do the above in an encapsulation unspecific way so that the
encapsulation type is eventually abstracted away from the user.
* Use the same forwarding decision for both native forwarding and
encapsulation thus allowing to switch between native IPv6 and
UDP encapsulation based on endpoint without requiring additional
logic

The fundamental changes introduces in this series are:
* A new RTA_ENCAP Netlink attribute for routes carrying encapsulation
instructions. Depending on the specified type, the instructions
apply to UDP encapsulations, MPLS and possible other in the future.
* Depending on the encapsulation type, the output function of the
dst is directly overwritten or the dst merely attaches metadata and
relies on a subsequent net_device to apply it to the packet. The
latter is typically used if an inner and outer IP header exist which
require two subsequent routing lookups to be performed.
* A new metadata_dst structure which can be attached to skbs to
carry metadata in between subsystems. This new metadata transport
is used to provide a single interface for VXLAN, routing and OVS
to communicate through metadata.

The OVS interfaces remain as-is but will transparently create a real
VXLAN net_device in the background. iproute2 is extended with a new
use cases:

VXLAN:
ip route add 40.1.1.1/32 encap vxlan id 10 dst 50.1.1.2 dev vxlan0

MPLS:
ip route add 10.1.1.0/30 encap mpls 200 via inet 10.1.1.1 dev swp1

Performance implications:
The additional memory allocation in the receive path should have
performance implications although it is not observable in standard
throughput tests if GRO is properly done. The correct net_device
model outweights the additional cost of the allocation. Furthermore,
this implication can be relaxed by reintroducing a direct unqueued
path from a software device to a consumer like bridge or OVS if
needed.
