>Description:
In /sys/scsi/scsi_ioctl.c the SCIOCCOMMAND ioctl is ifdef'ed out waiting
to be fixed to use copyin/copyout. Here are the comments from the section.
#ifdef notyet /* XXXX Needs to be redone to use copyin/out! */
case SCIOCCOMMAND: {
/*
* You won't believe this, but the arg copied in
* from the user space, is on the kernel stack
* for this process, so we can't write
* to it at interrupt time..
* we need to copy it in and out!
* Make a static copy using malloc!
*/
This basically make using the SCSI user passthru impossible. This is just
a friendly reminder to get this implemented soon.
