Topic

An update for ovn2.13 is now available in Fast Datapath for Red Hat
Enterprise Linux 8.

Description

OVN, the Open Virtual Network, is a system to support virtual network
abstraction. OVN complements the existing capabilities of OVS to add native support for virtual network abstractions, such as virtual L2 and L3 overlays and security groups.

• [RFE] Support MAC learning in OVN when port security is disabled for a logical port. (BZ#1672625)
• Abort packet should send when acl reject rules set for sctp session. (BZ#1841009)
• [OVN SCALE] ovn-controller stops listening/handling port claim events (BZ#1903210)
• --may-exist does not work correctly on lr-route-add (BZ#1916842)
• [OVN] ovn-controller crashing with "failed in flood_remove_flows_for_sb_uuid()" (BZ#1928012)
• [OVN] ovn-controller crashing with "failed in flood_remove_flows_for_sb_uuid()" (BZ#1929978)
• ovn-controller is crashing with the assertion - EMER|controller/binding.c:2507: assertion lb->pb && lb->iface failed in binding_seqno_run() (BZ#1930030)
• Loadbalancer hairpin no longer works when multiple load balancers exist on switches. (BZ#1931599)
