    Great let us know if it keeps giving you trouble!

    The link you gave does respond and allow permissions:

    if (metadata->fd >= 0) {

    /* Handle open permission event */

    if (metadata->mask & FAN_OPEN_PERM) {
    printf("FAN_OPEN_PERM: ");

    /* Allow file to be opened */

    response.fd = metadata->fd;
    response.response = FAN_ALLOW;
    write(fd, &response,
    sizeof(struct fanotify_response));
    }

    That's the key bit of the example... If you use gdb and never get to
    there, you are in a bit of trouble, I agree!
