Release 21.06.0

In addition to bug fixes, the 21.06.0 release of OVN contains a mix of new features and performance improvements.

New Features

  • A new version of ovn-northd is included. This version is written in Differential Datalog instead of C and processes incrementally.
  • VLAN passthru mode is supported.
  • Custom 802.11ad support for localnet ports is added.
  • An “allow-stateless” ACL option has been added that will always bypass conntrack.
  • DNS now responds to PTR requests.
  • There is now a “–dry-run” option for ovn-northd and ovn-northd-ddlog.

Performance Enhancements

  • The C version of ovn-northd can now process data in parallel threads.
  • ct.inv can be disabled for deployments where offloading to smart NICs is desired.
  • Similar to the ovn-nbctl daemon, ovn-sbctl has a daemon mode.
