Worked on integrating new socket timestamping flags into the rust-lang/libc repository to reflect recent Linux and Android kernel header changes. Focused on low-level programming and system programming, the contribution involved updating the library to support SOF_TIMESTAMPING_BIND_PHC, SOF_TIMESTAMPING_OPT_ID_TCP, and SOF_TIMESTAMPING_OPT_RX_FILTER, thereby enhancing network timing visibility for downstream applications. The implementation required a detailed understanding of operating system APIs and careful alignment with evolving kernel interfaces. Using C and Rust, the work ensured that libc remains compatible with the latest kernel features, supporting more precise network event tracking without introducing regressions or requiring major bug fixes during the period.
