[Qemu-devel] [Bug 1033727] [NEW] USB passthrough doesn't work anymore with qemu-kvm 1.1.1

[Klaus Hochlehnert]

Public bug reported:

Hi,

I have a "Bus 006 Device 002: ID 0d46:3003 Kobil Systems GmbH mIDentity Light / KAAN SIM III" (kind of smart card) in an USB port whitch I make available to a Windows XP guest.
This worked fine with every older qemu-kvm version I've used so far.

But since 1.1.0 it doesn't work anymore.
The device shows up in the guest, but the software can't access it anymore (and the guest is pretty unresponsive).

On the host I get every 2 seconds this message:
[ 7719.239528] usb 6-1: reset full-speed USB device number 2 using uhci_hcd

Command line options are:
/usr/bin/kvm
...
-device usb-host,vendorid=0x0d46,productid=0x3003,bus=usb.0,port=3
...

When I switch back to qemu-kvm 1.0.1 everything works fine again.
Any idea what the problem could be?

Thanks
Klaus

You should use git to bisect (the qemu tree) where it broke.

I think similar bug has been filed against qemu-kvm debian package
(http://bugs.debian.org/683983).  Will try to reproduce/bisect as time
permits.  Note the debian bugreport also mentions segfault on usb_del in
monitor.

[Michael Tokarev]

Ok.  I tried to bisect this, but it appears to be not so easy.  The
problem is that between 1.0 and 1.1, there's a lot of usb breakage, and
bisection leads to segfaults or assertion failures.


(qemu) usb_add host:003.002
usb_create: no bus specified, using "usb.0" for "usb-host"
(qemu) Segmentation fault

This is fixed in 8db36e9dddb1b6fab3554a8c00d92268b33a487b.


(qemu) usb_add host:003.002
(qemu) qemu-system-x86_64: /build/kvm/git/hw/usb.c:358: usb_packet_complete: Assertion `p->state == USB_PACKET_QUEUED' failed.


I skipped this commit, which lead to:


(qemu) usb_add host:003.002
(qemu) qemu-system-x86_64: /build/kvm/git/hw/usb.c:410: usb_packet_complete: Assertion `((&ep->queue)->tqh_first) == p' failed.


I'm continuing, but I've no much hope this will lead to anything useful at this rate.

I just tested with qemu-kvm 1.2.0
But basically still the same problem. Device shows up in the guest, but the software can't access it anymore.

Just the guest isn't unresponsive anymore.
And the dmesg message happens now only once in a while (but always two very close together):
[ 4066.239358] usb 6-1: reset full-speed USB device number 2 using uhci_hcd
[ 4066.498921] usb 6-1: reset full-speed USB device number 2 using uhci_hcd

I have made the same experiences with Ubuntu 12.10 (qemu-kvm 1.2.0). My
SmartCard reader Omnikey 3121 shows up in the guest but no card can be
found. No problem with quemu-kvm 1.0 under Ubuntu 12.04. See also my
report Bug #1073815.

Just an FYI for people that come across this bug: not all USB devices
are affected. USB passthrough is working for me with a Logitech C920
webcam in Ubuntu 12.10 (qemu-kvm 1.2.0), albeit with some video
freezing.

  I have a "Bus 006 Device 002: ID 0d46:3003 Kobil Systems GmbH mIDentity Light / KAAN SIM III" (kind of smart card) in an USB port which I make available to a Windows XP guest.
  This worked fine with every older qemu-kvm version I've used so far.

  But since 1.1.0 it doesn't work anymore.
  The device shows up in the guest, but the software can't access it anymore (and the guest is pretty unresponsive).

  On the host I get every 2 seconds this message:
  [ 7719.239528] usb 6-1: reset full-speed USB device number 2 using uhci_hcd

  Command line options are:
  /usr/bin/kvm
  ...
  -device usb-host,vendorid=0x0d46,productid=0x3003,bus=usb.0,port=3
  ...

  When I switch back to qemu-kvm 1.0.1 everything works fine again.
  Any idea what the problem could be?

  Thanks
  Klaus

Can someone go ahead and follow up on comment #6?  (Marking incomplete
in the meantime)

I'll mark as affecting the QEMU project since it has been confirmed
against 1.2.0 per comment #4.

Same here as what Uwe is experiencing : my SmartCard reader Omnikey 3121 shows up in the guest but no card can be found.
With qemu-kvm 1.2.0. Was working great with previous versions.

[Peter Schaefer]

Just confirming the bug. I'm having the same issues with the same USB
smart card reader as the submitter (Kobil mIDentity) on Debian Squeeze
using the qemu-kvm version 1.2.0 from debian-backports. Going back to
1.0 fixes the problem (http://snapshot.debian.org/package/qemu-
kvm/1.0%2Bdfsg-8~bpo60%2B1).

Since I can easily toggle between versions i could provide more support,
if wanted and instructions provided...

Referring to my last comment: The URL does only work if you add a
backslash at the end, sorry about that.

One last note: In Germany, the Kobil USB Reader is/was supplied by DATEV
(see http://www.datev.com/) to their members/partners. So, anybody who's
running DATEV software on kvm-virtualized systems will run into this
problem.

@Peter Schaefer,

(replying to comment #12) could you please follow up on comments #6 and
#7?

It also would be worthwhile, at this point, checking whether latest
upstream (1.3) is still broken.

Just a short note: I somehow produced a backported *.deb for 1.3.0 and
i managed to recompile the debs of 1.1.2 and 1.0 from debian backports
with "--enable-trace-backend=simple". The problematic box runs Debian
Squeeze with Kernel 3.2.35 (and some other packages) from backports.

Tomorrow evening i'm going to make test runs on the system. I'll keep
you posted.

   Peter

Hi again!

The good news: 1.3.0 works (at least with my setup). The bad news is
that this might lower the motivation to fix 1.1.2 ;-) ...

Attached is the USB trace file from the non-working case with V 1.1.2.

If decompressed, it's an 185 MB text file and - honestly - i cannot make
any sense of it, but here you have it... ;-)

There's two USB devices passed-through:

1) vendor=0x529 product=0x1 -> Hardlock USB Dongle
2) vendor=0xd46 product=0x3003 -> Kobil USB Smartcard Reader

HTH,
  Peter

Gerd, can you take a (maybe quick) look please?

This bug is quite old and, as Peter notes, may be fixed in 1.3
so there's no goo motivation to fix it for older version...
I tried to reproduce (to be able to get a trace, or bisect) it
several times on my machine but can't, even with devices other
people reported as triggering it.  Please give some advice for
Debian users ;)

Thank you!

Given the amount of fixes which went into usb (not just usb-host, but
also uhci/ehic emulation) since 1.1 there is nothing but upgrading I can
seriously suggest ...

Well.  Big share of these fixes are in the new async code which
were added for 1.2.  There aren't really much fixes for the original
wrong behavour.

I were looking at all usb-related changes since 1.1 up to current 1.3,
and there aren't really many fixes in there which are not already
picked for -stable.

But ofcourse I overlooked the actual fix for this problem, which
appears to be this commit:

commit 72a04d0c178f01908d74539230d9de64ffc6da19
Author: Hans de Goede <hdegoede@redhat.com>
Date:   Wed Sep 12 15:08:40 2012 +0200

      uhci: Don't queue up packets after one with the SPD flag set

      Don't queue up packets after a packet with the SPD (short packet detect)
      flag set. Since we won't know if the packet will actually be short until it
      has completed, and if it is short we should stop the queue.

      This fixes a miniature photoframe emulating a USB cdrom with the windows
      software for it not working.

      Signed-off-by: Hans de Goede <hdegoede@redhat.com>
      Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

which I wanted to queue for 1.1-stable too, initially, but decided
it isn't really needed ;)

Thank you!

Can you go ahead and push this into the 1.1-stable repo then? I'd
rather see things that are accepted pushed into the various stable
repos than languish in someone's personal repo/list and then pushed

I now updated the 1.1-queue tree, adding a few other things I picked
from various places, but it is still far from "complete' in any way.
(Note that I removed a few not-so-relevant changes from there, --
like "tools: initialize main loop before block layer" which isn't needed
since it fixes things broken after 1.2, so I had to rebase and force-push
it).  And I think we shuold release 1.1.3 finally.  But that's a different
topic.

[Michael Tokarev]

Peter, are you able to run git bisect or something like that, to try to
pinpoint either the commit which introduced this issue or which fixed
it?

I tried to reproduce this issue several times with various devices, but
I can't do it reliable, it always more or less works on my machine.  If
I were able to, I'd bisect it long time ago.

Now, to clarify things, I've no idea how USB works internally and how it
is implemented in qemu, for this issue I can only do a bisection to find
the changes which change the issue.

You can ping me by email or hit me on IRC (I'm mjt at freenode.net and
oftc.net) if you're willing to debug it further and need help in doing
that.

Besides, what are the sympthoms of the device non-working?  Does it
happen with linux guest too?  Have you tried re-running the guest again
when the problem occur, using the same problematic version of qemu - I
mean, is it 100% reproducible or happens at random?

Thank you!

  Hi,

  I have a "Bus 006 Device 002: ID 0d46:3003 Kobil Systems GmbH mIDentity Light / KAAN SIM III" (kind of smart card) in an USB port which I make available to a Windows XP guest.
  This worked fine with every older qemu-kvm version I've used so far.

  But since 1.1.0 it doesn't work anymore.
  The device shows up in the guest, but the software can't access it anymore (and the guest is pretty unresponsive).

  On the host I get every 2 seconds this message:

  Any idea what the problem could be?

Well, i'm no expert at git, but i made some progress, see below.

In my case it's the SmartCard-Reader that's not working, i.e. the DATEV Software called "Sicherheitspaket" does not 
work. The background process called "SiPaHost.exe" just hangs; any client program trying to display SmartCard 
information does also just hang forever. That behaviour is 100% reproducible and persists over reboots of the Linux host 
and/or the Windows guest (Windows XP SP3). I did not try Linux guests.

Yesterday, i used git to checkout all qemu-kvm versions from kernel.org and build Debian packets from it (source kept 
vanilla, i just applied the two patches that rename paths from 'qemuXXX' to 'kvmXXX').

The findings were:

- v1.0   -> ok
- v1.0.1 -> ok
- v1.1.0 -> not ok
- v1.1.1 -> not ok
- v1.1.2 -> not ok
- v1.2.0 -> not ok

So far, this is consistent with the findings in this bug report.

BUT: The latest HEAD from kernel.org (called "v1.2.50") also does work
again!

So, i'm now learning about git bisect (however, today i won't have time
for this).

Regards,
Peter

     uhci: Don't queue up packets after one with the SPD flag set

     Don't queue up packets after a packet with the SPD (short packet detect)
     flag set. Since we won't know if the packet will actually be short until it
     has completed, and if it is short we should stop the queue.

     This fixes a miniature photoframe emulating a USB cdrom with the windows
     software for it not working.

Thank you very much Peter for the work you did.  That is not of historic
interest, not at all - it is of a good value for Debian users!

And thank you Nikolaus for the testing, as well!

I take your (both of you!) words that the problem is now solved, and am
uploading new release to debian archives right now. At least it didn't
break things for me, -- I tested the resulting build and it works with
my usb devices, there's no immediately visible regression.  So hopefully
the bug is now fixed and I'm closing it in Debian.

Thank you again!

  ====================================
  SRU Justification:
  1. Impact: usb devices which worked with qemu previously stop working
  2. Development fix: a patch upstream entitled uhci: Don't queue up packets after one with the SPD flag set fixes the problem
  3. Stable fix: same patch as development fix.
  4. Test case: you must test with certain usb devices - see below for the exact kvm arguments to use.
  5. Regression potential: this patch is cherrypicked from upstream so should be safe.

Bug description:
  ====================================
  SRU Justification:
  1. Impact: usb devices which worked with qemu previously stop working
  2. Development fix: a patch upstream entitled uhci: Don't queue up packets after one with the SPD flag set fixes the problem
  3. Stable fix: same patch as development fix.
  4. Test case: you must test with certain usb devices - see below for the exact kvm arguments to use.
  5. Regression potential: this patch is cherrypicked from upstream so should be safe.
  ====================================

  Hi,

  I have a "Bus 006 Device 002: ID 0d46:3003 Kobil Systems GmbH mIDentity Light / KAAN SIM III" (kind of smart card) in an USB port which I make available to a Windows XP guest.
  This worked fine with every older qemu-kvm version I've used so far.

  But since 1.1.0 it doesn't work anymore.
  The device shows up in the guest, but the software can't access it anymore (and the guest is pretty unresponsive).

  On the host I get every 2 seconds this message:
  [ 7719.239528] usb 6-1: reset full-speed USB device number 2 using uhci_hcd

  Command line options are:
  /usr/bin/kvm
  ...
  -device usb-host,vendorid=0x0d46,productid=0x3003,bus=usb.0,port=3
  ...

  When I switch back to qemu-kvm 1.0.1 everything works fine again.
  Any idea what the problem could be?

  Thanks
  Klaus
