Return EEXISTS if requested file already exists, without this patch open call will always succeed even if the file exists and user specified O_CREAT|O_EXCL. Following test code can be used to verify this patch. Without this patch executing following test code on 9p mount will result in printing 'test case failed' always. main() { int fd; /* first create the file */ fd = open("./file", O_CREAT|O_WRONLY); if (fd < 0) { perror("open"); return -1; } close(fd); /* Now opening same file with O_CREAT|O_EXCL should fail */ fd = open("./file", O_CREAT|O_EXCL); if (fd < 0 && errno == EEXIST) printf("test case pass\n"); else printf("test case failed\n"); close(fd); return 0; } Signed-off-by: M.
