Developed foundational BPF networking timestamping capabilities in the netdata/libbpf repository, establishing a robust framework for precise network timing telemetry and performance analysis. The work introduced new bpf_get/setsockopt options and a comprehensive set of BPF sock_ops callbacks to surface key timestamping events, including scheduling, software send, hardware timestamping, acknowledgment, and sendmsg operations. Implemented in C with a focus on kernel development and network programming, the solution included safeguards to prevent interference with user-space timestamping. Maintained a clear, auditable commit history to support code review and future enhancements, enabling downstream metrics, debugging, and optimization for networking workloads.
