External DVD drive - connected when suspended, removed before resume.
Results in NULL pointer dereference in __blk_add_request on resume.
*ffffffff811d6503: 48 89 58 08 mov %rbx,0x8(%rax) |
%ebx = ffff880131559020 <--- faulting instruction
48 89 58 08 appears only in list_add :
static inline void list_add(struct list_head *new, struct list_head *head)
{
__list_add(new, head, head->next);
ffffffff81ac012c: 49 8b 04 24 mov (%r12),%rax
#ifndef CONFIG_DEBUG_LIST
static inline void __list_add(struct list_head *new,
struct list_head *prev,
struct list_head *next)
{
next->prev = new;
ffffffff81ac0130: 48 89 58 08 mov %rbx,0x8(%rax)
AFAICS list_add is only called from one place in __elv_add_request :
switch (where) {
case ELEVATOR_INSERT_REQUEUE:
case ELEVATOR_INSERT_FRONT:
rq->cmd_flags |= REQ_SOFTBARRIER;
** list_add(&rq->queuelist, &q->queue_head);
break;
Now, where is the patch? :)

You forgot to attach it?
This is clearly q == NULL, CC'ing James/linux-scsi. Oops left below.

OK, I think this patch should do the trick.

Check for device deletion before sending it a scsi command. This fixes an
OOPS I was seeing during resume when the external dvd drive was removed
while suspended.

While this will fix your particular oops, I don't think it's quite
right. It's fixing one particular piece of fall out from attempting to
talk to a removed device, it's not necessarily fixing the full class of
them. The other checks in scsi_set_medium_removal() aren't related to a
changing state of the device, they are capability checks.

While this will fix your particular oops, I don't think it's quite
right. It's fixing one particular piece of fall out from attempting to
talk to a removed device, it's not necessarily fixing the full class of
them. The other checks in scsi_set_medium_removal() aren't related to a
changing state of the device, they are capability checks.

Below patch pushes the check down to ioctl functions and hopefully should
cover more ioctl-on-gone-device cases by returning -ENXIO if an attempt
was made to submit request to a non-running device.
With this patch in place - instead of oopsing I now get a proper I/O error
on resume.
AFAICT from my limited SCSI layer knowledge - these seem to be the right
places to check. Would be interested in knowing if there are better/more
complete ways to handle this but if they are going to take time IMHO it
certainly doesn't hurt to keep the below patch in.

Can we please not duplicate complicated logic like that?
IOW, just make a helper function for it.
That said, isn't this all *exactly* what scsi_prep_state_check() is
supposed to check for? Why isn't that called, or if called, why isn't
it doing the right thing?

This is before you get that far, it's actually oopsing on inserting the
request on sdev->sdev_queue that is now NULL. The prep state checking
happens when sr/sd pulls the request off the queue for processing.

Ok, please just add a "sdev_alive(sdev)" helper that checks for sdev
&& sdev->sdev_queue. Apparently the issue isn't "this device is
SDEV_DEL, so don't send commands". Apparently the issue is literally
"don't oops".
Or maybe the prep state checking could be moved earlier. It seems
stupid to have a "can I do this command" function that is run too late
to actually catch the problems..

Yep, will do.

I don't think we can move it earlier, we essentially have to do the
check at both ends. The "normal" IO path would see that the queue is
dead and error the IO, but this is an internal setup that sets up the
request and then adds it to the stored queue pointer. So it needs to
check this state one way or the other. I think the above fix with the
sdev_alive() will be good enough.

If I understood it right we need checks in both places (kind of makes
sense as the device could be gone *after* we checked in ioctl function and
before the request queue was dereferenced). So here is the ioctl check
with a helper function for state check that Linus asked for.

Can somebody explain why it's those states, and nothing else?
Quite frankly, if it's about "don't oops on sdev->queue not existing",
then test for that. Not for some random and uncommented list of
states.

List of states and what commands if any are accepeted for each state are
explained in scsi_device.h enum definition of scsi_device_state :
enum scsi_device_state {
SDEV_CREATED = 1, /* device created but not added to sysfs
* Only internal commands allowed (for
inq) */
SDEV_RUNNING, /* device properly configured
* All commands allowed */
SDEV_CANCEL, /* beginning to delete device
* Only error handler commands allowed */
SDEV_DEL, /* device deleted
* no commands allowed */
SDEV_QUIESCE, /* Device quiescent. No block commands
* will be accepted, only specials (which
* originate in the mid-layer) */
SDEV_OFFLINE, /* Device offlined (by error handling or
* user request */
SDEV_BLOCK, /* Device blocked by scsi lld. No
* scsi commands from user or midlayer
* should be issued to the scsi
* lld. */
SDEV_CREATED_BLOCK, /* same as above but for created devices
*/
};
In this case - we check for cases where no commands are allowed and reject
those right away, leaving prep_state_check to do filtering at lower level
for which commands are allowed and which are not as the state permits.

So how do you fix the error or online it again? No chance it should
have commands passed to it to do that?
I don't know. My point is that I don't see why we should look at the
state at this point at all. We do that _later_.

Yeah - that makes sense. By that logic, looks like we can only disallow
for SDEV_DEL (if we decide to do that check here).

If we can do it later, well and good. I just didn't think it would hurt to
check upfront in ioctl if we are dealing with a dead device.

I don't think this is the root cause. I think q is non-NULL but has
already been released, so we're just getting a NULL deref on the actual
list head.
Does this fix it? It adds the refcounting at approximately the correct
places. Of course, we'll now be trying elevator operations on an extant
queue but one whose elevator functions have been destroyed, so there are
probably additional state guards to place.

[ Resend with URL - I got a bounce back from vger for attaching the OOPS JPEG ]
It doesn't seem to help. Machine locked up and I was dropped to text

Hmm. That's a different oops. It is now in scsi_prep_state_check().
At the beginning of it too. You can't see the "Code: " line in the
pictures, but the only dereference I see there is "sdev" itself being
NULL. And %cr2 is 0x640, which would seem to agree (the 'sdev'
structure is absolutely disgustingly big, and sdev->sdev_state is
indeed at an offset in that region.
That 'sdev' comes from scsi_prep_fn() doing
struct scsi_device *sdev = q->queuedata;
is that queuedata perhaps cleared even if the queue itself stays
around due to refcounts?

Different at top but the call trace upto scsi_set_medium_removal is the
same.
And since now we are upping the refcnt we keep the request queue around it
was kind of expected that it won't oops on the request queue.

So now the issue is with scsi_device refcnt?

No, I'd guess that the problem is just that __scsi_remove_device()
sets queuedata to NULL. Afaik, both sdev and the queue actually stay
around.
That said, I don't have very high opinions of some of the SCSI code.
And that's me being polite. The thing is a overcomplicated mess of
indirection and pointers back-and-forth. The refcounting is crazy
and/or impossible, since the pointers really do go back-and-forth.

Well, Jens wondered the same thing in this thread:
http://marc.info/?l=linux-scsi&m=130632292705404
It's just an RFC patch to see if I can fix an oops ... how it's
ultimately implemented will be up to Jens.

Apparently we can't do this because blk_[put|get]_queue aren't exported
for use in modules (and SCSI can be modular), so this caused a build
failure in linux-next.

OK, if you're fine with that, how does this patch look?
I can take it through my rc-fixes tree (with your ack), since I'm a bit
late on the merge window now.

Subject: [PATCH] [SCSI] Fix oops caused by queue refcounting failure
In certain circumstances, we can get an oops from a torn down device.
Most notably this is from CD roms trying to call scsi_ioctl. The root
cause of the problem is the fact that after scsi_remove_device() has
been called, the queue is fully torn down. This is actually wrong
since the queue can be used until the sdev release function is called.
Therefore, we add an extra reference to the queue which is released in
sdev->release, so the queue always exists.
Also export blk_queue_get/blk_queue_put for the refcounting.

Only the SCSI bit remains, so add at will. You can add my acked-by to
that standalone, if you wish.

I did some testing with this patch (using 3.0rc2 for reproducing it upstream, but the same behaviour
with 2.6.39 and e73e079bf128d68284efedeba1fbbc18d78610f9 applied).
ext2 and ext3 FS on the USB sticks are working fine, however I get the following oops when performing
the same test with the CDROM part of a sandisk cruzer:

Steps to reproduce:
1. mount /dev/sr0 /mnt # Mount fails
2. umount /mnt # Message about not being mounted
3. mount /dev/sr0 /mnt # [sr0] messages appears in kernel log
4. remove USB stick # USB disconnect message
5. umount /mnt # above error message
I mount the /dev/sr0 in /mnt and remove it before calling umount. I had to repeat the mount as it seemed to fail the first time (calling umount /mnt in-between). The second mount succeeded with some errors reported by the sr0.
Full logs attached as text file.

I did some testing with this patch (using 3.0rc2 for reproducing it upstream, but the same behaviour
with 2.6.39 and e73e079bf128d68284efedeba1fbbc18d78610f9 applied).
ext2 and ext3 FS on the USB sticks are working fine, however I get the following oops when performing
the same test with the CDROM part of a sandisk cruzer:

Steps to reproduce:
1. mount /dev/sr0 /mnt # Mount fails
2. umount /mnt # Message about not being mounted
3. mount /dev/sr0 /mnt # [sr0] messages appears in kernel log
4. remove USB stick # USB disconnect message
5. umount /mnt # above error message
I mount the /dev/sr0 in /mnt and remove it before calling umount. I had to repeat the mount as it seemed to fail the first time (calling umount /mnt in-between). The second mount succeeded with some errors reported by the sr0.
Full logs attached as text file.

The states are definitely wrong. QUIESCE shouldn't cause an error.
Can we back up a bit. I agree with Jens that sdev->request_queue looks
to be NULL, but that *only* happens in the final sdev release, so this
must be a refcounting problem higher up the stack. Something is holding
an unrefcounted pointer to the sdev.

QUIESCE is not causing an error above - > QUIESCE is which per the

Something strange is going on here. the q can't have been NULL when we
