RHBA-2024:10898 - Bug Fix Advisory

Topic

An update for ovn24.09 is now available for Fast Datapath for Red Hat Enterprise Linux 9.

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.

Bug Fix(es) and Enhancement(s):

• Changing NAT type=snat logical_ip to 0.0.0.0/0 breaks FIP to FIP communication (JIRA:FDP-744)
• ovn-northd doesn't immediately recompute on transaction failures (JIRA:FDP-753)
• CLONE [ovn24.09 fast-datapath-rhel-9] - When an ECMP symmetric route is removed, northd removes all logical flows from SBDB for ECMP (JIRA:FDP-837)
• CLONE [ovn24.09 fast-datapath-rhel-9] - Live-migration with Trunk ports: subports are flapping between hosts (source and destination) during the process (JIRA:FDP-859)
• CLONE [ovn24.09 fast-datapath-rhel-9] - ovn-northd IPAM incorrectly reports duplicate IP when part of excluded_ips (JIRA:FDP-895)
• CLONE [ovn24.09 fast-datapath-rhel-9] - can't get dhcpv4 address when add -s for dhclient (JIRA:FDP-896)
• OVN 24.09 24.H RHEL 9 Release (JIRA:FDP-912)
• [ovn24.09]ovn-controller would crash with basic ovn setup (JIRA:FDP-927)
