Worked on the linux-test-project/ltp repository to enhance the reliability of parallel test execution by addressing queue name collisions in inter-process communication. Applied system programming and concurrent programming skills in C to implement a fix that generates unique IPC queue names per process using getpid(), following the established mq_timedreceive01 approach. This solution resolved EEXIST failures that previously caused flaky test behavior during parallel runs, particularly when using the -w N option. The change was reviewed and validated by project maintainers, resulting in more stable and efficient continuous integration workflows without introducing additional overhead to the test infrastructure.
