Changed

• Multiple enhancements for FlowAggregator are introduced:
• Move aggregation logic from go-ipfix to Antrea for FlowAggregator. (#7227, @antoninbas)
• Remove several instances of log spam in the Flow Aggregator, and improve handling of connection failures. (#7223, @antoninbas)
• Set priorityClassName to system-node-critical by default for FlowAggregator. (#7124, @luolanzone)
• Support custom ClusterIDs attached to exported flow records for FlowAggregator. (#7197, @petertran-avgo)
• Clean up RBAC for FlowAggregator. (#7125, @antoninbas)
• Use Protobuf message in FlowAggregator to represent flows. (#7253, @antoninbas)
• Use Protobuf / gRPC between FlowExporter and FlowAggregator by default, and allow disabling IPFIX collector via aggregatorTransportProtocol. (#7264, @antoninbas)
• Add ability to export K8s UIDs in the IPFIX exporter. (#7279, @antoninbas)
• Add more configuration values to the flow-aggregator chart. (#7138, @antoninbas)
• Push flow-aggregator image to ghcr.io registry. (#7036, @antoninbas)
• Log error when OVS meter drops packets, which helps to evaluate whether increasing the packetInRate configuration is needed. (#7242, @tnqn)
• Log PacketIn drops when dispatching to per-category queues to improve troubleshooting. (#7174, @tnqn)
• Increase the default packet-in rate limit to 5000. (#7243, @tnqn)
• Sync affected groups in the Antrea Controller when a Pod goes into Terminated state, to ensure that the Pod is excluded from NetworkPolicy source and destination immediately. (#7217, @Dyanngg)
• Decouple sending of ICMP probes & latency reporting for NodeLatencyMonitor, which can improve accuracy of measurements and reduce system load. (#7189, @g4rud4kun)
• Add ICMP Rule for NodeLatencyMonitor to make it work when the Node is configured with iptables default DROP policy. (#7011, @Dhruv-J)
• Handle Pod UID updates in PodStore to account for the corner case where old and new Pods from update handler are actually different objects. (#6964, @antoninbas)
• Support configuring file permissions for the Antrea CNI configuration file. (#7098, @luolanzone)
• Install iptables rules to allow WireGuard packets to ensure Antrea with WireGuard can work properly when the Node is configured with iptables default DROP policy. (#7030, @wenyingd)
• Make IPPool prefixLength and gateway immutable. (#7186, @wenqiq)
• Periodically sync permanent neighbors to ensure route correctness for Antrea host gateway interface. (#7238, @hongliangl)
• Rename a SR-IOV VF device, which is configured as a secondary Pod interface, back to the original name when the Pod is deleted. (#7144, @luolanzone)
• Support removing the whole k8s.v1.cni.cncf.io/networks annotation or resetting it to an empty value, which deletes the Pod's SecondaryNetwork interfaces. (#7119, @wenqiq)
• Document Antrea native secondary network support for SR-IOV interfaces. (#7076, @tnqn)

Fixed

• Enhance OVS commands for Antrea Windows to accelerate container recovery and improve robustness. (#7228, @XinShuYang)
• Configure routes via ip route add to avoid incorrect replacement of routes when the interface is managed by a network daemon. (#7134, @luolanzone)
• Restore secondary VLAN interface information and reconcile OVS ports after Agent restarts. (#6853, @KMAnju-2021)
• Persist container netns with OVS port external IDs. (#7199, @[@jianjuns)
• Restore the existing SR-IOV secondary interface information when Agent restarts, using the information stored in the Pod NetworkStatus annotation, which ensures correct IP release and VF device name restoration after Pod deletion. (#7240, @luolanzone)
• Fix invalid template ID in FlowAggregator for IPFIX exporter. (#7208, @antoninbas)
• Fix race condition when getting metrics via antctl for FlowAggregator. (#7230, @antoninbas)
• Fix invalid IPFIX UDP traffic fragmentation in the Flow Aggregator. (#7080, @antoninbas)
• Fix invalid Antrea IE registry ID in docs. (#7087, @ColonelBundy)
• Remove stale local members in the group cache for Multicast, which resolves an issue that the same receiver may fail to receive multicast packets after it rejoins the group. (#7154, @wenyingd)
• Fix Agent crash when deleting the Secret storing BGP passwords. (#7042, @hongliangl)
• Fix rollback when configureContainerLinkVeth fails, to ensure subsequent retries can succeed. (#7210 #7213, @tnqn)
• Upgrade otelhttp to v0.55.0 to fix WriteHeader logging flood. (#7196, @DeeBi9)
