Worked on the linux-test-project/ltp repository to address a specific bug affecting hostname length handling in kernel tests. Focused on the gethostname test, the developer increased the buffer size to properly accommodate the null terminator for 64-character hostnames, resolving ENAMETOOLONG errors that previously caused unreliable test results. This targeted fix ensured that maximum-length hostnames were correctly processed, improving the reliability and stability of the test suite, especially for edge-case scenarios. The work involved C programming and leveraged skills in bug fixing, kernel testing, and system programming, ultimately strengthening continuous integration confidence for the linux-test-project/ltp codebase.
