During March 2026, work focused on enhancing the microsoft/retina repository by delivering TCX support within the packetparser plugin, targeting efficient BPF program attachment on Linux 6.6 and newer. The implementation introduced an enableTCX configuration and a kernel capability probe to automatically detect TCX availability, ensuring seamless fallback to TC when necessary. Attachment management was refactored using a unified map structure, improving lifecycle handling and cleanup reliability. The createQdiscAndAttach flow was updated to dynamically select the optimal attachment method at runtime. This feature was developed and validated locally using Go, leveraging expertise in BPF programming and Linux kernel development.

Mar 1, 2026March 2026 monthly summary for microsoft/retina: Delivered a major feature in the packetparser plugin by adding TCX support with auto-detection and enhanced attachment management for Linux 6.6+. A new enableTCX config gates the feature and a kernel capability probe (isTCXSupported) determines availability and gracefully falls back to TC when TCX is not supported. Reworked the attachment lifecycle to a unified map (attachmentMap/attachmentValue) and ensured correct cleanup on removal. The createQdiscAndAttach flow now selects attachViaTCX or attachViaTC based on runtime capability, enabling safer multi-program chaining with lower overhead. Local validation and testing were performed; work ties to Retina PR #1994 and addresses related project needs (e.g., microsoft/retina#1958).
