Kevin Hsiang contributed to the deepflowio/deepflow repository by enhancing network observability features and improving protocol inference accuracy. He developed an eBPF-based extension to the agent, enabling it to capture remote IP and port information for UDP datagrams by tracing recvfrom() system calls, which improved the granularity of network traffic analysis. Additionally, Kevin fixed a bug in HTTP/2 protocol detection by correcting the handling of the MAGIC segment within the HTTP/2 headers frame parser, reducing false negatives in traffic classification. His work demonstrated strong skills in C programming, network protocol analysis, and system-level eBPF instrumentation over a focused two-month period.

Jul 1, 2025July 2025: Key feature delivered in deepflowio/deepflow: Enhanced UDP telemetry by extending the eBPF agent to capture the remote IP and port of UDP datagrams. This is achieved by tracing recvfrom() and persisting network address details for improved traffic analysis. Commit 857bc4518f67acbbee7359f7456cdad3d61212b1 implements this feature, enabling more precise network visibility and analytics.

Jun 1, 2025June 2025: Fixed HTTP/2 MAGIC segment detection in protocol inference for the deepflow agent, correcting a previously skipped segment in parse_http2_headers_frame. Implemented in the deepflowio/deepflow repository with commit 1e0e3ce86736b6e6c49eb1dd4dff4ad0997d2435. This improvement enhances HTTP/2 traffic classification accuracy, observability, and reliability, reducing false negatives and delivering clearer data for operators.
