Worked on the kubeovn/kube-ovn repository to deliver MAC-only underlay subnet support, enabling MAC address allocation per pod while delegating IP assignment to external DHCP servers. This feature introduced a new ProtocolMac type for CIDR-less subnets, requiring substantial changes to the IPAM and controller logic in Go. The implementation included idempotent MAC allocation, per-interface provisioning, and robust resource tracking to support BYO-DHCP workflows. Comprehensive test coverage was added, spanning unit, controller-level end-to-end, and Multus NAD scenarios on Kubernetes. Refactoring improved code readability and maintainability, while enhancements to webhook logic and stale IP cleanup increased reliability for networking operations.

Jun 1, 2026June 2026 monthly summary for kubeovn/kube-ovn: Delivered MAC-only underlay subnet support with BYO-DHCP IP management, enabling MAC allocation per pod while delegating IP assignment to external DHCP servers. Key API and IPAM changes introduce ProtocolMac for MAC-only subnets (CIDR-less), with new MAC allocation flows, per-interface MAC provisioning, and idempotent behavior. Expanded test coverage across unit, controller-level e2e, and Multus NAD scenarios to validate MAC-only operation in real deployments. Refactored mac-only helpers for readability and maintainability, and hardened the end-to-end flow with fixes for webhook denial logic, excludeIps handling for MAC-only subnets, and cleanup of stale IPs to prevent MAC leaks. Added acceptance-style e2e specs under the underlay suite to verify correct Ready state and MAC-only NIC behavior on live KIND clusters. Overall, these changes reduce reliance on internal IPAM, improve operator reliability, and enable BYO-DHCP workflows with robust test coverage.
