Tue Aug 18 15:30:25 UTC 2020

The version of openvswitch in the proposed pocket of Eoan that was
purported to fix this bug report has been removed because the bugs that
were to be fixed by the upload were not verified in a timely (105 days)
fashion.

  [SRU] hw-tc-offload not reliable with VXLAN with OpenStack

Bug description:
  [Impact]
  Hardware offload VXLAN tunnel flows may not be correctly offloaded and are hence not functional in OpenStack deployments

  [Test Case]
  Deploy OpenStack configured with suitable network cards for hardware offload of VM interfaces
  Boot instances with hardware offloaded interfaces (capability=switchdev)
  Instances may or may not get DHCP configured depending on how OpenStack chooses to tag the flows associated with the VXLAN tunnel networking for the cloud.

  [Regression Potential]
  Low; proposed patch has been tested with OpenStack Stein and has been peer reviewed and landed into all OVS stable branches back to v2.8 and will be included in the next 2.12.x release (which would target Eoan)

  [Original Bug Report]
  OpenStack Train
  OVS 2.12

  Linux 5.3 from hwe edge

  Connect-X 5 running latest firmware from Mellanox.

  Overlay networking configured with VXLAN for project networking.

  Some instances successfully DHCP, some don't.

  For those that don't:

  compute:

  11:51:24.926581 IP bond1.2925.node-laveran.maas.58901 > bond1.2925.node-lepaute.maas.4789: VXLAN, flags [I] (0x08), vni 1233
  IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from fa:16:3e:e8:59:f3 (oui Unknown), length 300

  gateway:

  11:50:44.010864 IP bond1.2925.node-laveran.maas.58901 > bond1.2925.node-lepaute.maas.4789: VXLAN, flags [I] (0x08), vni 1233
  IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from fa:16:3e:e8:59:f3 (oui Unknown), length 300
  11:50:44.011196 IP bond1.2925.node-lepaute.maas.55067 > bond1.2925.node-laveran.maas.4789: VXLAN, flags [I] (0x08), vni 1233
  IP 172.16.0.2.bootps > 172.16.2.236.bootpc: BOOTP/DHCP, Reply, length 328

  The response is send from the gateway unit to the compute unit, but is
  never seen in the tcpdump.

  If hardware encap is disabled on the two underlying ports/the card,
  traffic flow is seen and all instances correctly DHCP configure on
  boot.
