Subject	Bug#986837: aoe: kernel crash on blk_update_request: I/O error, BUG: scheduling while atomic
Message-ID	<C38o9-1ja-3@gated-at.bofh.it>

Package: linux-image-amd64
Version: 5.10.26-1
Source: linux

Dear Maintainers,

It seems we found a race condition in the aoe driver that leads to a 
kernel crash. It is triggered when an aoe device is unavailable and 
therefore produces an I/O error in the code that tries to remove the 
device. (drivers/block/aoe/aoedev.c: aoedev_downdev)

example process to reproduce:
* add an aoe-target to a lvm2 volume group
* make the aoe target unavailable (e.g. set the network dev down) but 
don't flush it
* run a command that scans all physical volumes, e.g. 'vgs'
* wait for aoe to time out (default for aoe_deadsecs is 180s)

result: kernel crash

These messages continue until the machine is reset.

It seems to be a regression from commit 3582dd291788 ("aoe: convert 
aoeblk to blk-mq") and a similar bug has already been fixed [1].

running on kernel 4.19.0-16-amd64 we get the expected result that the 
aoe device is removed upon timeout. dmesg output:
[....]
[  301.543788] mlx4_en: enp65s0d1: Close port called

Hope someone can resolve this issue,

thanks for your help,

Thanks for the report. I assume you can reproduce the issue as well
with 5.10.28-1 in unstable?

Can you report the issue to upstream and loop in the bug?

Salvatore

Hi Salvatore,

I did not test this before as the aoe driver code was not changed at all 
in the last 7 months. I can now report that the behavior is exactly the 
same running the kernel 5.10.0-6-amd64 #1 SMP Debian 5.10.28-1 from 
unstable.

> Can you report the issue to upstream and loop in the bug?

Yes but i did not do this before. From what i can find i'd report to
the IO/STorage - Other section in bugzilla [1]  and mail to the listed 
maintainer "Justin Sanders" <justin@coraid.com>. Is that the way to go 
or did i forget something?

Valentin

Ack thanks for confirming that as well.

You can run the get_maintainer.pl script to get information where to
report the issue, it gives me:

$ ./scripts/get_maintainer.pl ./drivers/block/aoe/
Justin Sanders <justin@coraid.com> (supporter:ATA OVER ETHERNET (AOE) DRIVER)
Jens Axboe <axboe@kernel.dk> (maintainer:BLOCK LAYER)
linux-block@vger.kernel.org (open list:BLOCK LAYER)
linux-kernel@vger.kernel.org (open list)

So yes, this is the right approach, mail to Justin and Jens, keeping
the mailinglist in the loop.

Let me know if you need help here further!

Regards,
Salvatore

After waiting some weeks and in addition trying to reach out to 
support@coraid.com to find someone who might be willing to address this 
bug i unfortunately did not receive any response.
Do you have suggestions what i could do next? Unfortunately i do not 
think i have the skills to fix the bug myself.

Probably won't.  I think coraid no longer exists as of about 3 or 4 
years ago.  [if this is about aoe style systems]

Try something else?  :-(

Hi,

I finally managed to identify the root cause of this issue and do have a 
patch and a more detailed description of the issue attched to the kernel 
bugtracker.
The attached patch is applicable to stable (5.10.92) and experimental 
(5.17-rc4) kernels.
As I did not receive any response to the original upstream report, I 
fear that this might be the same for the proposed patch as well.
Do you have any suggestions on what to do?
I would now follow up with a mail to the maintainers, the linux-block 
list and the lkml but I don't know anything more I could try.

Regards,
Valentin
