Hi,
Build environment: debian sid, gcc-4.2.3, i386.
The bug is in lately git-pull from
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
And it can be reproduced very easily on a machine with normal cdroms.
It halts booting and I grabbed the bug output with an serial console.
Code around the bug is:
/*
* If DRQ is clear, the command has completed.
*/
if ((stat & DRQ_STAT) == 0) {
spin_lock_irqsave(&ide_lock, flags);
if (__blk_end_request(rq, 0, 0))
BUG(); // Here comes the bug !
HWGROUP(drive)->rq = NULL;
spin_unlock_irqrestore(&ide_lock, flags);
return ide_stopped;
}

I get this on boot on an Core Duo Lifebook E8110 with an DVD Recorder which
renders this kernel unusable:

Hi,
Sorry for the inconvenience.
I can't reproduce this bug on my test environment.
So please give me more information below to find what's wrong.

Could you give me all boot messages and your config?
Are you able to get some outputs on 2.6.24 + the patch below?
If yes, original ide-cd might have a problem.

Hi, I saw the same BUG from ide-cd on one of my systems. I applied
the debugging patch to replace the BUG with blk_dump_rq_flags(), and I
got the output below (full boot log and .config attached to this
email).
Please let me know if there's anything else that would help debug the
problem.

Bart,
This means that the rq still has a bio even after DRQ_STAT is cleared.
The original ide-cd code was calling only end_that_request_last() there.
So I thought that the rq should have no bio when DRQ_STAT is cleared,
otherwise the bio leaks.
Was my understanding wrong and is that correct behavior in ide-cd?
Thanks,
Kiyoshi Ueda

PS I'm extremely busy with "real-life" (unfortunately IDE hacking is not
my paid job) and the friday is the earliest date on which I would be able
to look in detail into this problem and other outstanding IDE stuff, sorry.

Same here, will be able to look into it tomorrow. In the meantime, can someone
direct me the full BUG() output?

I borrowed a box having the same nForce chipset and tried sg_inq
command to submit the GPCMD_INQUIRY ("cdb: 12" of the debug message).
I confirmed that ide-cd run through the code path (DRQ_STAT == 0)
by the same debug patch, but requests always don't have bio there
on my test box. So I can't reproduce the problem yet.
-----------------------------------------------------------------------
ide-cd: rq: dev hda: type=2, flags=114c8
sector 37958141, nr/cnr 0/0
bio 00000000, biotail f78e4980, buffer 00000000, data 00000000, len 0
cdb: 12 00 00 00 24 00 00 00 00 00 00 00 00 00 00 00
-----------------------------------------------------------------------
The original code was calling only end_that_request_last() here,
but no problem happened.
This may mean that the upper layer can handle the rq correctly,
no matter whether the rq still has a bio or not.
If so, we should be able to unlink the bio by calling
end_that_request_chunk() with remaining data size.
Roland,
Could you try the patch below and give me all boot messages again?
This patch displays debug messages against requests still having bio,
then tries to unlink all bios from the rq before the rq is completed.
So your system may be able to continue to work correctly
after displaying debug messages.
I'd like to see the debug messages and know whether your system
still gets the problem or not.

Sure, no problem, see below for full log (I updated to the latest git,
which seems to have some other unrelated problems with things timing
out earlier in the boot, but it does get to the ide-cd init); here's
the relevant looking debug info:

By the way, even with your first debug patch, I had no problem using
the box once it booted. I didn't try the CD-ROM but everything else
seemed fine.
Also, I saw the same issue on a different box (Dell SC1435 with
serverworks IDE):

And by the way, Kiyoshi,
This can be reproduced in a typical setup vmware workstation 6.02 with
a vritual IDE cdrom,
in case you wanna catch that with your own eyes. :-)
Thanks for your trying hard to correct this annoying bug.
Best Regards,
Nai

The below fix should be enough. It's perfectly legal to have leftover
byte counts when the drive signals completion, happens all the time for
eg user issued commands where you don't know an exact byte count.

Great, thanks for confirming that. I'll make sure the patch goes
upstream today, if Linus is available.

OK, I undarstand the leftover is legal.
By the way, is it safe to always return success if there is a leftover?
I thought we might have to complete the rq with -EIO in such case.

data_len being non zero should pass the residual count back to the
issuer.

Aah, so the issuer can know how many bytes of the I/Os are not done,
and the error status of the bio which is completed by
end_that_request_first() in __blk_end_request() don't matter
for the issuer.
OK, thanks. I think the patch is fine.

Actually, this behavior has been the case even before the __blk_end_request()
changes. I did test plain 2.6.24 with the following

end_that_request_last() is not called when __blk_end_reuqest()
returns 1. Then, the issuer isn't waken up.
So I think the BUG() or error messages should be there.
And fortunately, the issuer seems not to mind whether
end_that_request_first() is called for the remaining bio or not.
So I think Jens' patch is fine.

> So I think the BUG() or error messages should be there.
you mean, end_that_request_last() isn't called when __end_that_request_first()
returns an error and this is the case only for fs and pc requests. Otherwise it
_is_ called, thus simulating somewhat the previous behavior. However, we never BUG()'ged
on residual byte counts before and this driver has been in the kernel tree for
ages, so what puzzles me now is how is BUG()'ing here better than before and
shouldn't we simply issue a warning instead of killing the interrupt handler...
..or am i missing something?

The Jens' patch passes the residual byte counts to __blk_end_request(),
so __end_that_reqeust_first() should never return 1 and we should never
BUG() on the residual byte counts, unless inconsistency happens such as
the size of remaining bios is bigger than the residual byte counts.
So if __blk_end_request() returns 1 even with the Jens' patch,
it means that the block layer or the driver really have a bug.
And then, the request and the bios could leak or the issuer
would wait forever because end_that_request_last() isn't called.
The previous behavior might ignore such inconsistency and leak only
the bios because it was calling end_that_request_last() anyway.
I would like to BUG() in such cases personally, but I don't object
strongly if you prefer not to BUG().

yep.

BUG() is definitely what we should do here to catch this case of sizeof(bios) >
rq->data_len. Putting a brown paper bag over the issue will never get it fixed
if it really leaks bios. Thanks for clarifying that.
By the way, shouldn't we be doing a little branch prediction here:
diff --git a/drivers/ide/ide-cd.c b/drivers/ide/ide-cd.c
index 74c6087..bee05a3 100644
--- a/drivers/ide/ide-cd.c
+++ b/drivers/ide/ide-cd.c
@@ -1722,7 +1722,7 @@ static ide_startstop_t cdrom_newpc_intr(ide_drive_t *drive)
*/
if ((stat & DRQ_STAT) == 0) {
spin_lock_irqsave(&ide_lock, flags);
- if (__blk_end_request(rq, 0, 0))
+ if (unlikely(__blk_end_request(rq, 0, rq->data_len)))
BUG();
HWGROUP(drive)->rq = NULL;
spin_unlock_irqrestore(&ide_lock, flags);

I think it's reasonable.
