PROFILE
Anadi Sharma
Anadi Anand worked on cross-platform enhancements for the cilium/tetragon repository, focusing on porting core observability and process monitoring features from Linux to Windows. Over five months, Anadi refactored Linux-specific code using Go build constraints, centralized constants, and introduced Windows-specific modules for process lifecycle tracking, eBPF program loading, and event serialization. He improved CI/CD reliability by stabilizing Windows builds, pinning toolchain versions, and expanding automated test coverage. Using Go, C, and YAML, Anadi addressed platform differences in kernel event handling, timestamp conversion, and process ancestry logic, delivering robust, maintainable code that improved Windows support, build reproducibility, and cross-platform consistency.

Jul 1, 2025Concise monthly summary for 2025-07 focusing on Windows reliability and CI stability for tetragon (cilium/tetragon). Key features delivered: 1) Win32 Process Ancestry Tracking Correctness (bug fix) improving termination logic, orphan handling (assigning PID 4 to orphans), and liveness checks; 2) CI Build Stability on Windows by pinning LLVM to 18.1.8 to avoid incompatible updates with BPF builds. Major bugs fixed: applied precise fixes to Windows ancestry tracking and ensured a reproducible Windows build environment. Overall impact: enhanced accuracy of Windows process telemetry, reduced CI flakiness, and more reliable Windows-based BPF workflows, accelerating debugging and release cycles. Technologies/skills demonstrated: Windows kernel/user-space integration, process ancestry logic, CI tooling and environment hardening, LLVM-based build reproducibility, and Windows/BPF compatibility.

Jun 1, 2025June 2025: Focused on Windows-specific Tetragon enhancements to improve CI reliability and runtime sensor deployment. Delivered multi-program loading from a single collection with caching, extended eBPF loader support with GUID mappings for bind and sockops attach types, and fixed a CI exec-event UID regex edge-case to ensure stable test outcomes. These changes reduce CI flakiness, enable more flexible Windows sensor configurations, and improve maintainability and extensibility of the Windows loader.

May 1, 2025May 2025 monthly summary for cilium/tetragon focusing on Windows integration improvements, CI reliability, and cross-platform observability. Delivered Windows ring buffer enhancements with pinning the ringbuffer map by name and operation-code-based event dispatch, enabling more precise and scalable event processing. Strengthened Windows CI stability and alignment with the latest BPF programs, reducing flaky builds and ensuring tests run against current binaries. Expanded Windows attach types support in the Tetragon agent to allow dynamic program attachments beyond the default process attachment, improving versatility across workloads. Added User Login Identifier (LUID) to Windows process events to enhance security auditing and traceability, including updates to event structures and token retrieval. Fixed Windows-to-Linux epoch timestamp conversion in exec/exit event serialization to ensure accurate event timing across platforms. These contributions collectively improve observability, security auditing, and developer productivity, delivering tangible business value through more reliable data, faster iteration, and cross-platform consistency.
