Running the gnulib POSIX tests on Microsoft WSL (Windows Subsystem for Linux), I see only 5 test failures:
FAIL: test-fcntl ================ ../../gltests/test-fcntl.c:269: assertion 'errno == EINVAL' failed FAIL test-fcntl (exit status: 134) FAIL: test-poll =============== Unconnected socket test... passed Connected sockets test... failed (expecting POLLHUP after shutdown) General socket test with fork... failed (expecting POLLHUP after shutdown) Pipe test... passed FAIL test-poll (exit status: 2) FAIL: test-rename ================= ../../gltests/test-rename.h:342: assertion 'errno == EINVAL || errno == EBUSY || errno == EISDIR || errno == ENOTEMPTY || errno == EEXIST' failed FAIL test-rename (exit status: 134) FAIL: test-renameat =================== ../../gltests/test-rename.h:342: assertion 'errno == EINVAL || errno == EBUSY || errno == EISDIR || errno == ENOTEMPTY || errno == EEXIST' failed FAIL test-renameat (exit status: 134) FAIL: test-renameat2 ==================== ../../gltests/test-rename.h:342: assertion 'errno == EINVAL || errno == EBUSY || errno == EISDIR || errno == ENOTEMPTY || errno == EEXIST' failed FAIL test-renameat2 (exit status: 134) Which means that this implementation of the Linux kernel interface is quite mature w.r.t. POSIX compliance. As usual [1], let's allow the differing errno value here. It's unlikely that an application will rely on the precise errno values here. This reduces the number of failing tests to 1.
