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!
