about ll_rw_blk.c of void generic_make_request(struct bio *bio)

[erich]

Dear Jens Axboe,

I am an engineer of Areca (SATA RAID controller producer).
I have coding linux driver for kernel.org "arcmsr".
I have got dump message %s: rw=%ld, want=%Lu, limit=%Lu message from ext2 
file system.
But I am do well at Ext3 and all linux files system.
This issue only occur at read command.
Could you give me some info how to fix this bug in my linux scsi raid 
driver?

About the code ll_rw_blk.c mention that "it may well happen - the kernel 
calls bread() without checking the size of the device, e.g., when mounting a 
device."

I hope that you have more experience with it and knew what's wrong I am 
doing in my driver.


generic_make_request(struct bio *bio)

 if (maxsector)
 {
  sector_t sector = bio->bi_sector;

  if (maxsector < nr_sectors || maxsector - nr_sectors < sector)
  {
   /*
    * This may well happen - the kernel calls bread()
    * without checking the size of the device, e.g., when
    * mounting a device.
    */
   handle_bad_sector(bio);
   goto end_io;
  }
 }
Best Regards

I can't really say, from my recollection of leafing over lkml emails, I
seem to recall someone saying he hit this with a newer kernel where as
the older one did not?

What are the sectors exactly it complains about, eg the full line you
see?

I see:

  attempt to access beyond end of device
  sdb1: rw=0, want=134744080, limit=128002016

I believe the "rw=0" means that was a simple read request, and not a 
read-ahead.

128002016 equals about 62 gigs, which is the correct volume size:

  Filesystem           1K-blocks      Used Available Use% Mounted on
  /dev/sdb1             62995364   2832696  56962620   5% /xxx

  /dev/sdb1 on /xxx type ext2 (rw,noatime)

I'm at a loss as to why ext2 would want to read 3+ gigs past the end of 
the volume or why the arcmsr driver setting max_sectors to be 4096 instead 
of 512 makes a difference.

Erich, while using 4096 as the max_sectors count, in your lab can you make 
it so ll_rw_blk.c:handle_bad_sector() makes a call to dump_stack() after 
the printk's?  What does it show as the call trace?

Correct.

How are you reproducing this, through the file system (reading files),
or reading the device? If the former, is the file system definitely
sound - eg does it pass fsck?

It's truly puzzing why the 4k vs 512 would make a difference, except if
the driver really doesn't support that large requests and corrupts the
data somehow. I'm having an extraordinarily hard time imaging how the
SCSI layer could even come up with such a bug.

So everything seems to point us getting wrong data from the hardware,
most likely because of a driver bug in either handling the larger
transfers or the hardware just not liking them very much.

Probably wont tell you much.

Filesystem level interaction via bonnie++.  Basic repro is, using ccaputo 
user, is:

  mke2fs -j -L /xxx /dev/sdb1
  mount -t ext2 /dev/sdb1 /xxx
  cd /xxx ; mkdir ccaputo ; chown ccaputo ccaputo ; cd ccaputo ; su ccaputo
  /usr/sbin/bonnie++

Filesystem is believed to be sound since it is from a fresh mke2fs.

The one strange thing I do is that I format it as ext3 (-j) but mount it 
as ext2, but I didn't think that would be an issue and I'd be surprised if 
Erich is doing the same in his tests, which also fail, with ext2.  (I do 
it in case I later decide to mount the volume as ext3.)

Dear Chris Caputo,

I am so sorry that I reply this mail today.
At 2006/4/3 my mother unexpectedly got paralysis and dead.
I can not do any more "request testing" with this bug for some days.
I do dump_stack as your request and attach it.
And I do "fsck" before test this volume every time.
It appears fine when do fsck with each testing volume.
You can easily reproduce this bug from copy a 900MB file from ARECA volume 
(mkfs.ext2, mount -t ext2) to none ARECA volume.

Best Regards
Erich Chen

Erich, my sincere condolences to you and your family.

With respect to this problem, is it possible with your driver that if a 
transfer read request is above a certain size, data corruption occurs?

It may be that fsck passes because it is doing smaller transfers while a 
file copy under ext2 (or in your example, ext3) fails because it is during 
those operations that the higher max_sectors makes a difference.

Curiously, the hex values of the "want=" field in your report are as 
follows:

  sdb1: rw=0, want=12126966488, limit=312496317
  2D2D2D2D8
  sdb1: rw=0, want=12126967088, limit=312496317
  2D2D2D530
  sdb1: rw=0, want=22232771288, limit=312496317
  52D2D2AD8
  sdb1: rw=0, want=22232771888, limit=312496317
  52D2D2D30

I wonder if 0x2D or 0xD2 corresponds to something on the disk such as in 
the file being copied or is otherwise familiar.

Re: about ll_rw_blk.c of void generic_make_request(struct bio *bio)

[erich]

Dear Chris Caputo,

I will do any research when I come back my lab.
You can do mkfs.ext3 /dev/sda1.
and then mount -t ext3 /dev/sda1 /mnt/sda1
test this volume as your testing procedure.
If in this case it cause same message as we met, please tell me again.

Best Regards
Erich
