Hello!
I'm author of xmcd port to FreeBSD platform.
I received some reports from users that claims that xmcd SCSI
interface does not work any more on 2.0.5R.
After some checking i find out that SCIOCCOMMAND ioctl always fail
with "permission denied".
Looking at /sys/scsi/scsi_ioctl.c line 260:
/* If we can't write the device we can't permit much:
*/
if (cmd != SCIOCIDENTIFY && !(flags & FWRITE))
return EACCES;
After commenting out this 2 lines and recompiling the kernel
xmcd started to work fine.
All i need to know is how to call this ioctl so it will not fail.
(I have write permission on the device and i get "permission denied"
even if i'm running xmcd as root).
Any help will be appreciated.
