Release Notes:
OVN v21.06.0 - 18 Jun 2021
-------------------------
- ovn-northd-ddlog: New implementation of northd, based on DDlog. This
implementation is incremental, meaning that it only recalculates what is
needed for the southbound database when northbound changes occur. It is
expected to scale better than the C implementation, for large deployments.
(This may take testing and tuning to be effective.) This version of OVN
requires DDLog 0.38.
- Introduce ovn-controller incremental processing engine statistics
- Introduced parallel processing in ovn-northd with the NB_Global config option
'use_parallel_build' to enable it. It is disabled by default.
- Support vlan-passthru mode for tag=0 localnet ports.
- Support custom 802.11ad EthType for localnet ports.
- Add a new NB Global option - use_ct_inv_match with the default value of
true. If this is set to false, then the logical field - "ct.inv" will not
be used in the logical flow matches. CMS can consider setting this to
false, if they want to use smart NICs which don't support offloading
datapath flows with this field used.
- Introduce a new "allow-stateless" ACL verb to always bypass connection
tracking. The existing "allow" verb behavior is left intact.
- Added support in native DNS to respond to PTR request types.
- ovn-nbctl daemon mode is no longer considered experimental.
- Utilities:
* ovn-nbctl daemon mode is no longer considered experimental.
* ovn-sbctl now also supports daemon mode.
- Added support in native DNS to respond to PTR request types.
- New --dry-run option for ovn-northd and ovn-northd-ddlog.
