March 2025 monthly summary for microsoft/ebpf-for-windows focusing on reliability improvements and CI/CD modernization. Key outcomes include improved NetEbpfExt service stop robustness with enhanced cleanup, diagnostics, and retry logic, and a CI/CD modernization using 1es runners across Windows Server 2022, 23H2, and 2025, leading to faster feedback and reduced shutdown risks.

February 2025 monthly summary for microsoft/ebpf-for-windows: Strengthened Windows test infrastructure and stability, delivering WS2025 and 23h2 test coverage in scheduled CI, and implementing stability fixes for kernel-mode stress tests. The work improved test reliability, expanded coverage for Windows targets, and accelerated feedback to developers. Key decisions included onboarding tests to scheduled pools, consolidating CI/CD/test setup, and applying a temporary workaround to unblock tests while NetEbpfExt stop issues are investigated.

Month: 2024-12 — Focus: Feature delivery for microsoft/ebpf-for-windows with a new debugging capability that enhances observability of the filter-context lifecycle. Implemented Zombie List Debugging for Deleted Filter Contexts by tracking and persisting information about removed filter contexts. The list is populated during removal and is active in non-debug builds to avoid impacting debug performance. Introduced new APIs for zombie-list management and adjusted the cleanup process to support the debugging mechanism. No major bugs fixed this month; the emphasis was on delivering the feature with production-friendly behavior and traceability.

November 2024 monthly summary for microsoft/ebpf-for-windows focused on stabilizing cross-platform builds and ensuring reliable compilation across x64, Win32, and ARM64. Implemented a targeted fix to the constexpr mutex constructor by introducing a build property flag to disable constexpr mutex construction where necessary, preventing platform-specific compile-time issues and reducing CI failures.
