Hello I have a USB based ID 148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter, that stops working with recent kernels. It works on kernel 5.1.15 and does not work with 5.2.7 or 5.3.1 (I have not tested other versions). I use it in AP mode.

I found this similar bug report https://marc.info/?l=linux-wireless&m=156630037103575&w=2 but that did not have related error messages so I assume this is different?

Logs of working kernel 5.1.15-arch1-1-ARCH.

This most likely is the problem introduced by commit:

commit e383c70474db32b9d4a3de6dfbd08784d19e6751
Author: Stanislaw Gruszka <sgruszka@redhat.com>
Date:   Tue Mar 12 10:51:42 2019 +0100

    rt2x00: check number of EPROTO errors

Plase check below patch that increase number of EPROTO checks 
before marking device removed. If it does not help, plese
check if reverting above commits helps.

So, revert of that commit makes the problem gone ?

It's printk. You can add line like this to print values:

printk("status %d num_proto_errs %u\n", status, rt2x00dev->num_proto_errs);

| So, revert of that commit makes the problem gone ?

No I have not yet tested that. Have had too much stuff going on and this is kinda low priority for me right now as it currently works on the old kernel.

So i got around to this again:

Changes to linux-5.6.0 drivers/net/wireless/ralink/rt2x00/rt2x00usb.c were:

static bool rt2x00usb_check_usb_error(struct rt2x00_dev *rt2x00dev, int status)
{
  if (status == -ENODEV || status == -ENOENT)
    return true;

  if (status == -EPROTO || status == -ETIMEDOUT) {
    rt2x00dev->num_proto_errs++;
+    printk("status %d num_proto_errs %u\n", status, rt2x00dev->num_proto_errs);
  } else
    rt2x00dev->num_proto_errs = 0;

- if (rt2x00dev->num_proto_errs > 8)
-    return true;

  return false;
}

As the error count is very high at the start but no more errors after that i assume some part of the initialization is not supported by my device, any suggestions how to figure out what exactly? Device works fine afterwards, but i have not done any serious connection testing beyond simple transfer test, getting 3MB/s sustained transfer rate both ways which is enough for me.

I added a dump_stack() call below the printk to help to narrow it down more.

and 509 is the last error, so it seems like it is the load_firmware process that is giving all the errors.

As clarification device works after this with no further errors when using.

I would like to get this resolved, is there any more information you need from me?

I have been manually patching this all year with:

drivers/net/wireless/ralink/rt2x00/rt2x00usb.c
- if (rt2x00dev->num_proto_errs > 8)
-    return true;

It seems to just be some part of rt2800_load_firmware that is not supported on my device and generating errors but it has been running without problems in AP mode with daily usage.

lsusb -v (with unpatched linux-lts, i don't normally use lts kernel):

Should we do a revert? Can someone submit that including an explanation
of the regression.

Lo, this is your Linux kernel regression tracker speaking.

Thx for this, that's how it got on the radar of regzbot, my Linux kernel
regression tracking bot:

Afaics nothing happened since then. Or did I miss anything? How can we
get the ball rolling again?

Stanislaw, is there anything Exuvo (who offered to help afaics) could
test to get us closer to a fix?

Ciao, Thorsten

P.S.: I have no personal interest in this issue and watch it using
regzbot. Hence, feel free to exclude me on further messages in this
thread after the first reply, as I'm only posting this mail to hopefully
get a status update and things rolling again.

Sending this again, but this time also to Stanislaw's email address
currently found in MAINTAINERS.

Stanislaw, can you help with this regression?

Helmut: or can you help somehow to get things rolling again?

Ciao, Thorsten, your Linux kernel regression tracker

Yes. 

I'll check on mail archives what is the status and what can be done.

Ok, so what I can see here  
https://lore.kernel.org/linux-wireless/20211109073127.GA109212@wp.pl/T/#m6a677995c1afaf6b9b1ff19de9566f304089d3ac
is that this problem happen only on firmware load,
so I think we can use below patch as fix.

Anton, please test it.

Thanks
Stanislaw

Just tested it and it passes the rt2x00lib_load_firmware but still errors on rt2800usb_set_device_state:

Eh, I sent from my phone to give quick update, did not realize
it send in HTML.

Anyway, below is updated patch. I hope it will work correctly now.

As reported by Exuvo is possible that we have lot's of EPROTO errors
during device start i.e. firmware load. But after that device works
correctly. Hence marking device gone by few EPROTO errors done by
commit e383c70474db ("rt2x00: check number of EPROTO errors") caused
regression - Exuvo device stop working after kernel update. To fix
disable the check during device start.

Hi, this is your Linux kernel regression tracker speaking. Thx for this fix.

FWIW: In case you need to send an improved patch, could you
please add this before the 'Reported-by:' (see at (¹) below for the
reasoning):

Link:
https://lore.kernel.org/linux-wireless/bff7d309-a816-6a75-51b6-5928ef4f7a8c@exuvo.se/

And if the patch is already good to go: could the subsystem maintainer
please add it when applying?

> Fixes: e383c70474db ("rt2x00: check number of EPROTO errors")

What's the plan to getting this merged? Just wondering, because there
*afaics* wasn't any activity for a week now. Yes, e383c70474db was a
commit for v5.2-rc1, so it's not a new regression that needs to be
handled really urgently. But it's still a regression that would be good
to get fixed rather sooner than later, as there might be still people
out there then might run into this on a update.

Ciao, Thorsten (carrying his Linux kernel regression tracker hat)


(¹) Long story: The commit message would benefit from a link to the
regression report, for reasons explained in
Documentation/process/submitting-patches.rst. To quote:

```
If related discussions or any other background information behind the
change can be found on the web, add 'Link:' tags pointing to it. In case
your patch fixes a bug, for example, add a tag with a URL referencing
the report in the mailing list archives or a bug tracker; [...]
```

This concept is old, but the text was reworked recently to make this use
case for the Link: tag clearer. For details see:
https://git.kernel.org/linus/1f57bd42b77c

Yes, that "Link:" is not really crucial; but it's good to have if
someone needs to look into the backstory of this change sometime in the
future. But I care for a different reason. I'm tracking this regression
(and others) with regzbot, my Linux kernel regression tracking bot. This
bot will notice if a patch with a Link: tag to a tracked regression gets
posted and record that, which allowed anyone looking into the regression
to quickly gasp the current status from regzbot's webui
(https://linux-regtracking.leemhuis.info/regzbot ) or its reports. The
bot will also notice if a commit with a Link: tag to a regression report
is applied by Linus and then automatically mark the regression as
resolved then.

IOW: this tag makes my life a regression tracker a lot easier, as I
otherwise have to tell regzbot manually when the fix lands. :-/


P.S.: As a Linux kernel regression tracker I'm getting a lot of reports
on my table. I can only look briefly into most of them. Unfortunately
therefore I sometimes will get things wrong or miss something important.
I hope that's not the case here; if you think it is, don't hesitate to
tell me about it in a public reply. That's in everyone's interest, as
what I wrote above might be misleading to everyone reading this; any
suggestion I gave they thus might sent someone reading this down the
wrong rabbit hole, which none of us wants.

BTW, I have no personal interest in this issue, which is tracked using
regzbot, my Linux kernel regression tracking bot
(https://linux-regtracking.leemhuis.info/regzbot/). I'm only posting
this mail to get things rolling again and hence don't need to be CC on
all further activitie wrt to this regression. Ohh, and feel free to
ignore the following lines, they are meant for regzbot:

#regzbot poke

Sure, I'll add it during commit.

My plan is to commit this to wireless-drivers tree, the tree was just
closed due to the merge window.
