[Bug 1877797] Re: Neutron remote security group does not work in UCA Rocky and Stein - fixed upstream

[James Troup]

** Description changed:

- The Rocky release notes
- (https://docs.openstack.org/releasenotes/neutron/rocky.html) contain
- this entry for 13.0.7:
+ Remote security groups are broken in the UCA Rocky and Stein versions of
+ Neutron.
  
- Fixes an issue that the OVS firewall driver does not configure security
- group rules using remote group properly when a corresponding remote
- group has no port on a local hypervisor. For more information see bugs:
- 1862703 and 1854131.
+ The broken patch was introduced in LP #1854131 and fixed in LP #1862703.
  
- Unfortunately Rocky in the Ubuntu Cloud Archive is only 13.06 and we hit
- this problem with a customer cloud that was being upgraded to Stein and
- it caused workload network outages for them.
+ The relevant fixed has landed in Neutron 13.0.7 for Rocky¹.
  
- I realize Rocky is out of support at this point, but the supported
- upgrade path for Queens to Stein, includes upgrading to Rocky.  Can we
- please get 13.07 or later into the UCA for Rocky?
+ The relevant fixed landed in Neutron 14.1.0-37 for Stein², alternatively
+ the specific fix is available here:
+ 
+ https://github.com/openstack/neutron/commit/4193c6ca0e0165a2bcc7a11eee775df15019e755
+ 
+ The version of Queens currently in UCA (12.1.0) doesn't appear to have
+ the bad patch from #1854131 in it.
+ 
+ We ran into this while upgrading a customer cloud and it caused several
+ hours of VM connectivity downtime while we diagnosed it.  Please upgrade
+ Neutron in the Ubuntu Cloud Archive to have this fix available for at
+ least Rocky and Stein.
+ 
+ I realise Rocky is no longer supported, but given that the supported
+ upgrade path from Queens is via Rocky, I think it needs fixed there too.

  several hours of VM connectivity downtime while we diagnosed it.
