(please CC replies)
A while back I started noticing problems with KDE's CD handling.
Accompanying the problems (interminable waiting while it reads the CD
being the main one) were kernel messages as follows:
(scsi1:A:5:0): No or incomplete CDB sent to device.
scsi1: Issued Channel A Bus Reset. 1 SCBs aborted
sr 1:0:5:0: SCSI error: return code = 0x70000
This happens on kernels 2.6.14-rc3 and above, but not -rc1. I'm not
sure about -rc2 because of compile errors.
After digging through KDE's source, I've condensed the offending code to
a program that exhibits the behavior:
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <sys/ioctl.h>
#include <linux/cdrom.h>
static int wm_scsi(int fd, unsigned char *cdb, int cdblen,
void *retbuf, int retbuflen, int getreply)
{
struct cdrom_generic_command cdc = { 0 };
struct request_sense sense = { 0 };
int capability;
capability = ioctl(fd, CDROM_GET_CAPABILITY);
if(!(capability & CDC_GENERIC_PACKET)) exit(1);
memcpy(cdc.cmd, cdb, cdblen);
cdc.buffer = retbuf;
cdc.buflen = retbuflen;
cdc.stat = 0;
cdc.sense = &sense;
cdc.data_direction = getreply ? CGC_DATA_READ : CGC_DATA_WRITE;
return ioctl(fd, CDROM_SEND_PACKET, &cdc);
}
static int sendscsi(int fd, void *buf,
unsigned int len, int dir,
unsigned char a0, unsigned char a1,
unsigned char a2, unsigned char a3,
unsigned char a4, unsigned char a5,
unsigned char a6, unsigned char a7,
unsigned char a8, unsigned char a9,
unsigned char a10, unsigned char a11)
{
int cdblen = 0;
unsigned char cdb[12] = { 0 };
cdb[0] = a0;
cdb[1] = a1;
cdb[2] = a2;
cdb[3] = a3;
cdb[4] = a4;
cdb[5] = a5;
switch((a0 >> 5) & 7)
{
case 0:
cdblen = 6;
break;
case 5:
cdb[10] = a10;
cdb[11] = a11;
cdblen = 12;
case 1: case 2: case 6:
cdb[6] = a6;
cdb[7] = a7;
cdb[8] = a8;
cdb[9] = a9;
if(cdblen == 0) cdblen = 10;
break;
default:
exit(2);
}
return wm_scsi(fd, cdb, cdblen, buf, len, dir);
}
int main(void)
{
int fd;
char buf[36] = { 0 };
fd = open("/dev/sr0", O_RDONLY | O_NONBLOCK);
if(fd == -1) exit(3);
sendscsi(fd, buf, sizeof buf, 1, GPCMD_INQUIRY,
0, 0, 0, 36, 0, 0, 0, 0, 0, 0, 0);
return 0;
}
Now, the error message about an incomplete CDB does seem to indicate a
program error, not a kernel error. However, this same program works
fine on 2.6.13 so I would like to verify where, exactly, the problem
lies.
This might be related to the issue mentioned in
http://www.ussg.iu.edu/hypermail/linux/kernel/0510.3/1001.html
My SCSI controller is an Adaptec AIC-7902 U320 (onboard) and my DVD
