Developed a cross-distribution NFS UDP test enhancement for the microsoft/lisa repository, focusing on improving test reliability and compatibility across various Linux environments. The solution replaced a distribution-specific skip with a generic server-side portlist check, leveraging Linux system programming and network file systems expertise. By inspecting /proc/fs/nfsd/portlist, the tests now accurately detect UDP support and skip gracefully when necessary, reducing flaky results. A robust fallback was implemented for older kernels lacking the portlist, ensuring backward compatibility. The work, written in Python and emphasizing test automation, led to more stable CI outcomes and streamlined onboarding for future contributors through clear documentation.
