DVD_AUTH ioctl fails with aic7xxx / 2.4.4
I've set up a Pioneer 305S scsi dvd-rom on an old adaptec card using the
stock aic7xxx driver included with the 2.4.4 kernel (not the old_aic7xxx
one). Everything works well, except when trying to access an encrypted
file on a DVD. This ioctl from libcss fails:
static int _get_title_key(int fd, int agid, int lba, char *key, char *key_title)
{
dvd_authinfo ai;
int i;
ai.type = DVD_LU_SEND_TITLE_KEY;
ai.lstk.agid = agid;
ai.lstk.lba = lba;
if (ioctl (fd, DVD_AUTH, )) {
perror ("GetTitleKey failed");
return -1;
}
All I see from the kernel is:
sr1: CDROM (ioctl) reports ILLEGAL REQUEST.
This happens with any DVD. Can someone tell me what the problem is? I
seem to be using the same libcss that everyone else uses with no
problem, and everything is properly configured, AFAIK.
thanks,
Jason
