[PATCH] usb-storage: Ignore UAS for LaCie Rugged FW USB3

[PATCH] usb-storage: Ignore UAS for LaCie Rugged FW USB3

[Tasos Sahanidis]

This external HDD fails when plugged in to a USB 3 port. Ignoring UAS and
falling back to mass storage resolves this issue.

What happens when it is plugged into a USB-2 port?

Have you checked to see if any of the quirk flags can prevent this 
problem?  It looks like the only issue might be that one Mode Sense(6) 
command.

Falling back from uas to usb-storage could reduce the throughput 
considerably.  We would like to avoid doing this if possible.

It works without any quirks over USB 2.0 with uas, however asking for
cache data fails gracefully.

I have tried various combinations of all the available quirks and I
couldn't get it to not hang. Without any quirks it keeps retrying Mode
Sense(6) constantly.

I tested US_FL_ALWAYS_SYNC as it sets sdev->skip_ms_page_8 (both with
and without US_FL_NO_REPORT_OPCODES | US_FL_NO_SAME), and it hung at an
ATA passthrough command; presumably the next step afterwards.

30 seconds and one USB reset later, the disk is recognised, but I
do not know if it is reliable.

My assumption is that something goes wrong during init and that makes it
hang in general. Perhaps the Mode Sense(6) is broken in addition to
whatever else is misbehaving. I don't believe the XHCI controller is at
fault.

Absolutely, but at the same time I am not sure how much it matters for
an old mechanical hard disk. Granted, someone can use the same enclosure
and install an SSD internally, so perhaps that makes it worth it.

This seems to be similar to the issue I am facing with a similar LaCie 
Rugged USB3-FW 059f:1061. Initially we patched it to IGNORE_UAS but it 
then turned out to be working with US_FL_NO_REPORT_OPCODES and 
US_FL_NO_SAME. This was back in September 2021. In August 2023 I 
reported a similar issue as you, I am still seeing it in 6.7.3. The good 
news is that after initial problems it seems to be working fine once the 
USB connection is established.

I have now narrowed it down to having broken between 5.18.19 and 5.19.4 
kernels. Tasos, if you are interested, you might want to check if you 
can get the drive working with US_FL_NO_REPORT_OPCODES and
US_FL_NO_SAME alone (fk) quirks alone on Fedora 36 live, which ships 
5.17.5 kernel. Exercise caution as it is an EOL system.
I will see if I can narrow down the regression further.

Best regards,
Julian

Oddly enough, with 5.19.4 the device starts working after one reset 
instead of after four:

Further bisecting is going to be difficult as there are no built kernels 
left. I will see if the time effort is manageable.

So I have good news and bad news. The good news is that I have managed 
to bisect the issue down to commit

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c92a6b5d6335

With c92a6b5d6335 and with e60ac0b9e445, the drive requires multiple 
resets in the VM. With 7fb019c46eee onwards, it only requires one reset.
The bad news is that I am not able to fix it with BLIST_NO_VPD_SIZE:

$ echo "LaCie:Rugged FW USB3:0x2000" | sudo tee /proc/scsi/device_info

This is despite this being used to fix problems with some other devices:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4b1a2c2a8e0ddcb89c5f6c5003bd9b53142f69e3

I am cross-posting this to scsi list, maybe someone there would be able 
to understand what is going on.
Out of interest, why is the device called "Rugged FW USB3" by scsi but 
"Rugged USB3-FW" by usb?

Best regards,
Julian

I'm going to copy you on a patch I have in my development tree. I would
appreciate if you could try that out.

Thanks!

Hi Martin,

Thanks for responding. I tried your patch but it, unfortunately, did not 
help with the issue I and Tasos were having. Not on its own, and not 
with LaCie:Rugged FW USB3:0x2000 added to /proc/scsi/device_info.
Just to make sure we are talking about the same problem: prior to 
c92a6b5d6335, the drive would be usable pretty much immediately after 
connecting - in the logs this manifests by the following rows appearing:

Feb 13 18:59:42 kernel:  sdb: sdb1 sdb2
Feb 13 18:59:42 kernel: sd 8:0:0:0: [sdb] Attached SCSI disk

After c92a6b5d6335, one or more restarts are required (below is from 
Fedora's 6.7.4 with your patch applied on top):

Four resets are needed with the current kernel-6.7.4. With early 5.19 
kernels on and after 7fb019c46eee it needed one reset, with c92a6b5d6335 
and with e60ac0b9e445 multiple resets were needed too. As 30 seconds 
need to pass between the resets, it does take a while until the drive 
can be used.
I did not test other commits between c92a6b5d6335 and c92a6b5d6335 as I 
was bisecting and only tested the commits suggested by git.
6.7.4 I tested with bare metal Fedora 39, 5.19 with a Fedora 36 VM.
If this was already clear, please feel free to ignore.
In case it is relevant: my drive (but not Tasos') is patched to use 
US_FL_NO_REPORT_OPCODES | US_FL_NO_SAME.

Best regards,
Julian

OK, I see. I think I have an idea what's going on. Let me try a couple
of things...

USB takes the name provided by USB descriptors.
SCSI takes it from some VPD, IIRC.
