[Bug 2032605] Re: [FFe] Update OVN to new 23.09.0 upstream version

[Utkarsh Gupta]

Hi,

Thanks for filing an FFe. I think this broadly makes sense and ovn
releases are pretty stable and tested. As for now, I see the following
changelog entries:

Post v23.06.0
-------------
  - Added FDB aging mechanism, that is disabled by default.
    It can be enabled per logical switch with other_config
    "fdb_age_threshold".
  - Add DHCPv6 "fqdn" (39) option, that works similarly to
    DHCPv4 "hostname" (12) option.
  - Support to create/update MAC_Binding when GARP received from VTEP (RAMP)
    switch on l3dgw port.
  - To allow optimizing ovn-controller's monitor conditions for the regular
    VIF case, ovn-controller now unconditionally monitors all sub-ports
    (ports with parent_port set).
  - ECMP routes use L4_SYM dp-hash by default if the datapath supports it.
    Existing sessions might get re-hashed to a different ECMP path when
    OVN detects the algorithm support in the datapath during an upgrade
    or restart of ovn-controller.

Given this is not yet final, I don't think we can take that call right
now. I mean, as I said, in broader terms it should be OK but how about
this - once this is released and the changelog is finalized, we can
circle back on this and take a decision?

Feel free to ping me or release team members on IRC and we'll take
another look.

Just to be clear - I am not an official release team member yet. :)

Title:
  [FFe] Update OVN to new 23.09.0 upstream version

Status in ovn package in Ubuntu:
  New

Bug description:
  As detailed in an upstream announcement [0], the OVN 23.09.0 release
  is delayed. The estimated date for release is Friday September 15th.

  This new upstream version includes fixes and new features that are
  important for our community, and we would like to include it in the
  Ubuntu Mantic release.

  Our plan towards the Ubuntu release is the following:
  - Upload a snapshot based on the upcoming 23.09 branch if FFe is ACK'd.
  - As soon as the upstream release is cut we will upload a final package based on the released source artifacts.
