[Bug 1751396] Re: DVR: Inter Tenant Traffic between two networks and connected through a shared network not reachable with DVR routers

[Corey Bryant]

This bug has been fixed in the neutron 12.0.5 stable point release via 
https://bugs.launchpad.net/cloud-archive/+bug/1795424. neutron 12.0.5 was 
tested with a tempest smoke test run against a juju-deployed openstack as 
described in https://wiki.ubuntu.com/OpenStackUpdates.
Please see test results at: 
https://bugs.launchpad.net/cloud-archive/+bug/1795424/comments/17

Thanks,
Corey

[Corey Bryant]

This SRU is no longer needed as we're uploading neutron 12.0.5 to bionic
(queens) which includes this fix.

I don't think the regression testing is sufficient for this SRU
verification, please follow the test case in the description to verify
that this is fixed.

[Bug 1751396] Re: DVR: Inter Tenant Traffic between two networks and connected through a shared network not reachable with DVR routers

[Timo Aaltonen]

Hello Swaminathan, or anyone else affected,

Accepted neutron into bionic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/neutron/2:12.0.4-0ubuntu1 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

[Bug 1751396] Re: DVR: Inter Tenant Traffic between two networks and connected through a shared network not reachable with DVR routers

[Corey Bryant]

This does not affect Ubuntu Pike because neutron 11.0.5 does not include
the original patches that are being reverted.

** Description changed:

  Inter Tenant Traffic between Two Tenants on two different private
  networks connected through a common shared network (created by Admin) is
  not route able through DVR routers

  (NOTE: No external, just shared network)
  This is only reproducable in Multinode scenario. ( 1 Controller - 2 compute ).

[Bug 1751396] Re: DVR: Inter Tenant Traffic between two networks and connected through a shared network not reachable with DVR routers

[Arjun Baindur]

Hi, this appears to have broken DVR functionality for a simple shared
tenant network. The DVR flows translating the DVR macs are missing on
the physical bridges now for a VLAN based network. This tenant network
is shared, and only attached to 1 router.

As you can see port_shared_only is set to True here because its shared
and not an external network.

I think we need more checks here - seems like it was intended only for a shared 
network that acts as a link between 2 routers, but doesnt attach any compute 
ports?

DVR: Inter Tenant Traffic between networks not possible with shared net

Inter Tenant Traffic between two different networks that belong
to two different Tenants is not possible when connected through
a shared network that are internally connected through DVR
routers.

This issue can be seen in multinode environment where there
is network isolation.

The issue is, we have two different IP for the ports that are
connecting the two routers and DVR does not expose the router
interfaces outside a compute and is blocked by ovs tunnel bridge
rules.

This patch fixes the issue by not applying the DVR specific
rules in the tunnel-bridge to the shared network ports that
are connecting the routers.

Closes-Bug: #1751396
Change-Id: I0717f29209f1354605d2f4128949ddbaefd99629
(cherry picked from commit d019790fe436b72cb05b8d0ff1f3a62ebd9e9bee)
