Coverity wants the return value of mkdir() to be checked: /qemu/tests/qtest/libqos/virtio-9p.c: 48 in create_local_test_dir() 42 /* Creates the directory for the 9pfs 'local' filesystem driver to access. */ 43 static void create_local_test_dir(void) 44 { 45 struct stat st; 46 47 g_assert(local_test_path != NULL); >>> CID 1435963: Error handling issues (CHECKED_RETURN) >>> Calling "mkdir(local_test_path, 511U)" without checking return value. This library function may fail and return an error code. 48 mkdir(local_test_path, 0777); 49 50 /* ensure test directory exists now ... */ 51 g_assert(stat(local_test_path, &st) == 0); 52 /* ... and is actually a directory */ 53 g_assert((st.st_mode & S_IFMT) == S_IFDIR); So let's just do that and log an info-level message at least, because we actually only care if the required directory exists and we do have an existence check for that in place already.
