datapath-windows: Add IPv6 Geneve tunnel support in Windows
In the first step OVS Windows will support IPv6 tunnel(Geneve IPv6 tunnel).
Implementation on Windows
-------------------------
1. For the IPv6 tunnel support, OvsIPTunnelKey will replace original
OvsIPv4TunnelKey in the related flow context handing.
2. The related src and dst address will be changed to SOCKADDR_INET type from UINT32.
3. For the IPv6 tunnel, one node running OVS-Windows could encapsulate IPv4/IPv6
Packets via IPV6 Geneve Tunnel, and the node could also encapsulate IPv4/IPv6 packet
Via IPv4 Geneve tunnel.
4. Related IPHelper data structure will be adapted to support IPv6 Tunnel. In the IPHelper
part the related Windows API(such as GetUnicastIpAddressTable/GetBestRoute2/GetIpNetEntry2/
ResolveIpNetEntry2) and Windows data structure(MIB_IPFORWARD_ROW2/MIB_IPNET_ROW2/IP_ADDRESS_PREFIX)
Have already supported both IPv4 and IPV6. Now OVS Windows has been adjusted some functions
And data structured to support IPV6 tunnel also.
5. OVS_TUNNEL_KEY_ATTR_IPV6_SRC and OVS_TUNNEL_KEY_ATTR_IPV6_DST filed will be supported in
OVS-Windows kernel for IPV6 tunnel.
Testing done.
-------------------------
Related topo, 1 Windows VM(Win2019) and 2 Ubuntu 16.04 server. Both VMs
Are running on one ESX host.
1. Setup one IPV6 Geneve Tunnel between 1 Windows VM and 1 Ubuntu server.
Windows VM, vif0( 6000::2/40.1.1.10) vif1(5000::2)—— Ubuntu VM Eth2(5000::9), name space ns1
with interface ns1_link_peer(6000::9/40.1.1.2)
Related tunnnel,
ovs-vsctl.exe add-port br-int bms-tun0 -- set interface bms-tun0 type=Geneve options:csum=true
options:key=flow options:local_ip="5000::2" options:remote_ip=flow
In this topo, traffic from Vif0(Win) to ns1_link_peer(Ubuntu) will be gone through the Geneve tunnel
(5000::2—>5000::9) for both IPv4 traffic(40.1.1.10-->40.1.1.2) and IPv6 traffic(6000::2—>6000::9)
2. Setup one IPV4 Geneve Tunnel between Windows VM and 1 Ubuntu server.
Windows VM, vif0( 6000::2/40.1.1.10) vif1(50.1.1.11)—— Ubuntu, Eth2(50.1.1.9), name space ns1
with interface ns1_link_peer(6000::19/40.1.1.9)
Related tunnnel,
ovs-vsctl.exe -- set Interface bms-tun0 type=geneve options:csum=true options:key=flow
options:local_ip="50.1.1.11" options:remote_ip=flow
In this topo, traffic from Vif0(Win) to ns1_link_peer(Ubuntu) will be gone through the Geneve Tunnel
(50.1.1.11—>50.1.1.9) for both IPv4 traffic(40.1.1.10-->40.1.1.9) and IPv6 traffic(6000::2—>6000::19).
3.Regression test for IpV4 in Antrea project (about 60 test case) is PASS
Future Work
-----------
Add other type IPv6 tunnel support for Gre/Vxlan/Stt.
