RHBA-2023:4683 - Bug Fix Advisory

Topic

An update for ovn22.12 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.

Bug Fix(es) and Enhancement(s):

• Multichassis ports on localnet-attached logical switches should receive ICMP Path Discovery hints if their effective MTU is lower than localnet MTU (BZ#2180955)
• [ovn-controller] nb_cfg value over a certain value causes erroneous update to SB DB (BZ#2223480)
