[Bug 1813007] Please test proposed package

[Łukasz Zemczak]

Hello Diko, or anyone else affected,

Accepted neutron into bionic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/neutron/2:12.0.5-0ubuntu4 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 for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  It appears that we have found that neutron-openvswitch-agent appears to have a bug where two security group rules that have two different port ranges that overlap tied to the same parent security group will cause neutron to not be able to configure networks on the compute nodes where those security groups are present.
  Those are the broken security rules: https://pastebin.canonical.com/p/wSy8RSXt85/
  Here is the log when we discovered the issue: https://pastebin.canonical.com/p/wvFKjNWydr/

  
  Ubuntu SRU Details
  ------------------
  [Impact]
  Neutron openvswitch agent crashes due to creation of two security groups that both use the same remote security group, where the first group doesn't define a port range and the second one does (one is a subset of the other; specifying no port range is the same as a full port range).

  [Test case]
  See comment #18 below.

  [Regression Potential]
  The fix is fairly minimal and has landed upstream in master branch. It has therefore passed all unit and function tests that get run in the upstream gate and has been reviewed by upstream neutron core reviewers. This all helps to minimize the regression potential.
