Pull networking updates from David Miller:

Changes of note:

 1) Allow to schedule ICMP packets in IPVS, from Alex Gartrell.

 2) Provide FIB table ID in ipv4 route dumps just as ipv6 does, from
    David Ahern.

 3) Allow the user to ask for the statistics to be filtered out of
    ipv4/ipv6 address netlink dumps.  From Sowmini Varadhan.

 4) More work to pass the network namespace context around deep into
    various packet path APIs, starting with the netfilter hooks.  From
    Eric W Biederman.

 5) Add layer 2 TX/RX checksum offloading to qeth driver, from Thomas
    Richter.

 6) Use usec resolution for SYN/ACK RTTs in TCP, from Yuchung Cheng.

 7) Support Very High Throughput in wireless MESH code, from Bob
    Copeland.

 8) Allow setting the ageing_time in switchdev/rocker.  From Scott
    Feldman.

 9) Properly autoload L2TP type modules, from Stephen Hemminger.

10) Fix and enable offload features by default in 8139cp driver, from
    David Woodhouse.

11) Support both ipv4 and ipv6 sockets in a single vxlan device, from
    Jiri Benc.

12) Fix CWND limiting of thin streams in TCP, from Bendik Rønning
    Opstad.

13) Fix IPSEC flowcache overflows on large systems, from Steffen
    Klassert.

14) Convert bridging to track VLANs using rhashtable entries rather than
    a bitmap.  From Nikolay Aleksandrov.

15) Make TCP listener handling completely lockless, this is a major
    accomplishment.  Incoming request sockets now live in the
    established hash table just like any other socket too.

    From Eric Dumazet.

15) Provide more bridging attributes to netlink, from Nikolay
    Aleksandrov.

16) Use hash based algorithm for ipv4 multipath routing, this was very
    long overdue.  From Peter Nørlund.

17) Several y2038 cures, mostly avoiding timespec.  From Arnd Bergmann.

18) Allow non-root execution of EBPF programs, from Alexei Starovoitov.

19) Support SO_INCOMING_CPU as setsockopt, from Eric Dumazet.  This
    influences the port binding selection logic used by SO_REUSEPORT.

20) Add ipv6 support to VRF, from David Ahern.

21) Add support for Mellanox Spectrum switch ASIC, from Jiri Pirko.

22) Add rtl8xxxu Realtek wireless driver, from Jes Sorensen.

23) Implement RACK loss recovery in TCP, from Yuchung Cheng.

24) Support multipath routes in MPLS, from Roopa Prabhu.

25) Fix POLLOUT notification for listening sockets in AF_UNIX, from Eric
    Dumazet.

26) Add new QED Qlogic river, from Yuval Mintz, Manish Chopra, and
    Sudarsana Kalluru.

27) Don't fetch timestamps on AF_UNIX sockets, from Hannes Frederic
    Sowa.

28) Support ipv6 geneve tunnels, from John W Linville.

29) Add flood control support to switchdev layer, from Ido Schimmel.

30) Fix CHECKSUM_PARTIAL handling of potentially fragmented frames, from
    Hannes Frederic Sowa.

31) Support persistent maps and progs in bpf, from Daniel Borkmann.

FDB Ageing
^^^^^^^^^^
There are two FDB ageing models supported: 1) ageing by the device, and 2)
ageing by the kernel. Ageing by the device is preferred if many FDB entries
are supported. The driver calls call_switchdev_notifiers(SWITCHDEV_FDB_DEL,
...) to age out the FDB entry. In this model, ageing by the kernel should be
turned off. XXX: how to turn off ageing in kernel on a per-port basis or
otherwise prevent the kernel from ageing out the FDB entry?
The bridge will skip ageing FDB entries marked with NTF_EXT_LEARNED and it is
the responsibility of the port driver/device to age out these entries. If the
port device supports ageing, when the FDB entry expires, it will notify the
driver which in turn will notify the bridge with SWITCHDEV_FDB_DEL. If the
device does not support ageing, the driver can simulate ageing using a
garbage collection timer to monitor FBD entries. Expired entries will be
notified to the bridge using SWITCHDEV_FDB_DEL. See rocker driver for
example of driver running ageing timer.
In the kernel ageing model, the standard bridge ageing mechanism is used to age
out stale FDB entries. To keep an FDB entry "alive", the driver should refresh
the FDB entry by calling call_switchdev_notifiers(SWITCHDEV_FDB_ADD, ...). The
To keep an NTF_EXT_LEARNED entry "alive", the driver should refresh the FDB

################################################################################
Using iproute2 for VRFs
=======================
VRF devices do *not* have to start with 'vrf-'. That is a convention used here
for emphasis of the device type, similar to use of 'br' in bridge names.
1. Create a VRF
To instantiate a VRF device and associate it with a table:
$ ip link add dev NAME type vrf table ID
Remember to add the ip rules as well:
$ ip ru add oif NAME table 10
$ ip ru add iif NAME table 10
$ ip -6 ru add oif NAME table 10
$ ip -6 ru add iif NAME table 10
Without the rules route lookups are not directed to the table.
For example:
$ ip link add dev vrf-blue type vrf table 10
$ ip ru add pref 200 oif vrf-blue table 10
$ ip ru add pref 200 iif vrf-blue table 10
$ ip -6 ru add pref 200 oif vrf-blue table 10
$ ip -6 ru add pref 200 iif vrf-blue table 10
2. List VRFs
To list VRFs that have been created:
$ ip [-d] link show type vrf
NOTE: The -d option is needed to show the table id
For example:
$ ip -d link show type vrf
11: vrf-mgmt: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether 72:b3:ba:91:e2:24 brd ff:ff:ff:ff:ff:ff promiscuity 0
vrf table 1 addrgenmode eui64
12: vrf-red: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether b6:6f:6e:f6:da:73 brd ff:ff:ff:ff:ff:ff promiscuity 0
vrf table 10 addrgenmode eui64
13: vrf-blue: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether 36:62:e8:7d:bb:8c brd ff:ff:ff:ff:ff:ff promiscuity 0
vrf table 66 addrgenmode eui64
14: vrf-green: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether e6:28:b8:63:70:bb brd ff:ff:ff:ff:ff:ff promiscuity 0
vrf table 81 addrgenmode eui64
Or in brief output:
$ ip -br link show type vrf
vrf-mgmt UP 72:b3:ba:91:e2:24 <NOARP,MASTER,UP,LOWER_UP>
vrf-red UP b6:6f:6e:f6:da:73 <NOARP,MASTER,UP,LOWER_UP>
vrf-blue UP 36:62:e8:7d:bb:8c <NOARP,MASTER,UP,LOWER_UP>
vrf-green UP e6:28:b8:63:70:bb <NOARP,MASTER,UP,LOWER_UP>
3. Assign a Network Interface to a VRF
Network interfaces are assigned to a VRF by enslaving the netdevice to a
VRF device:
$ ip link set dev NAME master VRF-NAME
On enslavement connected and local routes are automatically moved to the
table associated with the VRF device.
For example:
$ ip link set dev eth0 master vrf-mgmt
4. Show Devices Assigned to a VRF
To show devices that have been assigned to a specific VRF add the master
option to the ip command:
$ ip link show master VRF-NAME
For example:
$ ip link show master vrf-red
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP mode DEFAULT group default qlen 1000
link/ether 02:00:00:00:02:02 brd ff:ff:ff:ff:ff:ff
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP mode DEFAULT group default qlen 1000
link/ether 02:00:00:00:02:03 brd ff:ff:ff:ff:ff:ff
7: eth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop master vrf-red state DOWN mode DEFAULT group default qlen 1000
link/ether 02:00:00:00:02:06 brd ff:ff:ff:ff:ff:ff
Or using the brief output:
$ ip -br link show master vrf-red
eth1 UP 02:00:00:00:02:02 <BROADCAST,MULTICAST,UP,LOWER_UP>
eth2 UP 02:00:00:00:02:03 <BROADCAST,MULTICAST,UP,LOWER_UP>
eth5 DOWN 02:00:00:00:02:06 <BROADCAST,MULTICAST>
5. Show Neighbor Entries for a VRF
To list neighbor entries associated with devices enslaved to a VRF device
add the master option to the ip command:
$ ip [-6] neigh show master VRF-NAME
For example:
$ ip neigh show master vrf-red
10.2.1.254 dev eth1 lladdr a6:d9:c7:4f:06:23 REACHABLE
10.2.2.254 dev eth2 lladdr 5e:54:01:6a:ee:80 REACHABLE
$ ip -6 neigh show master vrf-red
2002:1::64 dev eth1 lladdr a6:d9:c7:4f:06:23 REACHABLE
6. Show Addresses for a VRF
To show addresses for interfaces associated with a VRF add the master
option to the ip command:
$ ip addr show master VRF-NAME
For example:
$ ip addr show master vrf-red
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP group default qlen 1000
link/ether 02:00:00:00:02:02 brd ff:ff:ff:ff:ff:ff

valid_lft forever preferred_lft forever
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP group default qlen 1000
link/ether 02:00:00:00:02:03 brd ff:ff:ff:ff:ff:ff
inet 10.2.2.2/24 brd 10.2.2.255 scope global eth2
valid_lft forever preferred_lft forever
inet6 2002:2::2/120 scope global
valid_lft forever preferred_lft forever
inet6 fe80::ff:fe00:203/64 scope link
valid_lft forever preferred_lft forever
7: eth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop master vrf-red state DOWN group default qlen 1000
link/ether 02:00:00:00:02:06 brd ff:ff:ff:ff:ff:ff
Or in brief format:
$ ip -br addr show master vrf-red
eth1 UP 10.2.1.2/24 2002:1::2/120 fe80::ff:fe00:202/64
eth2 UP 10.2.2.2/24 2002:2::2/120 fe80::ff:fe00:203/64
eth5 DOWN
7. Show Routes for a VRF
To show routes for a VRF use the ip command to display the table associated
with the VRF device:
$ ip [-6] route show table ID
For example:
$ ip route show table vrf-red
prohibit default
broadcast 10.2.1.0 dev eth1 proto kernel scope link src 10.2.1.2
10.2.1.0/24 dev eth1 proto kernel scope link src 10.2.1.2

local 10.2.2.2 dev eth2 proto kernel scope host src 10.2.2.2
broadcast 10.2.2.255 dev eth2 proto kernel scope link src 10.2.2.2
$ ip -6 route show table vrf-red
local 2002:1:: dev lo proto none metric 0 pref medium
local 2002:1::2 dev lo proto none metric 0 pref medium
2002:1::/120 dev eth1 proto kernel metric 256 pref medium

local fe80:: dev lo proto none metric 0 pref medium
local fe80:: dev lo proto none metric 0 pref medium
local fe80::ff:fe00:202 dev lo proto none metric 0 pref medium
local fe80::ff:fe00:203 dev lo proto none metric 0 pref medium
fe80::/64 dev eth1 proto kernel metric 256 pref medium
fe80::/64 dev eth2 proto kernel metric 256 pref medium
ff00::/8 dev vrf-red metric 256 pref medium
ff00::/8 dev eth1 metric 256 pref medium
ff00::/8 dev eth2 metric 256 pref medium
8. Route Lookup for a VRF
A test route lookup can be done for a VRF by adding the oif option to ip:
$ ip [-6] route get oif VRF-NAME ADDRESS
For example:
$ ip route get 10.2.1.40 oif vrf-red
10.2.1.40 dev eth1 table vrf-red src 10.2.1.2
cache
$ ip -6 route get 2002:1::32 oif vrf-red
2002:1::32 from :: dev eth1 table vrf-red proto kernel src 2002:1::2 metric 256 pref medium
9. Removing Network Interface from a VRF
Network interfaces are removed from a VRF by breaking the enslavement to
the VRF device:
$ ip link set dev NAME nomaster
Connected routes are moved back to the default table and local entries are
moved to the local table.
For example:
$ ip link set dev eth0 nomaster
