/* In the following, the device /dev/cua2, does not physically exist. Therefore, the following routine should return a -1 and set errno in some manner.
Instead, it hangs. If you ^C, it crashes. This relates to the setterm problem that gives people Oopses upon startup. Setterm tries to open each of these devices. It is done when an open fails.
*/
#include <stdio.h> #include <unistd.h> #include <errno.h> #include <sys/fcntl.h>
main() { int fd;
fd = open("/dev/cua2", O_RDWR|O_NONBLOCK, 0); fprintf(stdout, "Open() returned %d, (%s)\n", fd, strerror(errno)); return 0; }
Linux 2.1.15 This bug was reported by myself as soon as the patch was available. I discovered the bug as soon as I booted with the patched kernel.
