USB: EHCI: bugfix: urb->hcpriv should not be NULL

2012-12-17T19:07:43+00:00

commit 2656a9abcf1ec8dd5fee6a75d6997a0f2fa0094e upstream.

This patch (as1632b) fixes a bug in ehci-hcd.  The USB core uses
urb->hcpriv to determine whether or not an URB is active; host
controller drivers are supposed to set this pointer to a non-NULL
value when an URB is queued.  However ehci-hcd sets it to NULL for
isochronous URBs, which defeats the check in usbcore.

In itself this isn't a big deal.  But people have recently found that
certain sequences of actions will cause the snd-usb-audio driver to
reuse URBs without waiting for them to complete.  In the absence of
proper checking by usbcore, the URBs get added to their endpoint list
twice.  This leads to list corruption and a system freeze.

The patch makes ehci-hcd assign a meaningful value to urb->hcpriv for
isochronous URBs.  Improving robustness always helps.

cdc-acm: implement TIOCSSERIAL to avoid blocking close(2)

2012-12-17T19:07:41+00:00

commit ba2d8ce9db0a61505362bb17b8899df3d3326146 upstream.

Some devices (ex Nokia C7) simply don't respond at all when data is sent
to some of their USB interfaces.  The data gets stuck in the TTYs queue
and sits there until close(2), which them blocks because closing_wait
defaults to 30 seconds (even though the fd is O_NONBLOCK).  This is
rarely desired.  Implement the standard mechanism to adjust closing_wait
and let applications handle it how they want to.

xhci: Extend Fresco Logic MSI quirk.

2012-12-17T19:07:22+00:00

commit bba18e33f25072ebf70fd8f7f0cdbf8cdb59a746 upstream.

Ali reports that plugging a device into the Fresco Logic xHCI host with
PCI device ID 1400 produces an IRQ error:

 do_IRQ: 3.176 No irq handler for vector (irq -1)

Other early Fresco Logic host revisions don't support MSI, even though
their PCI config space claims they do.  Extend the quirk to disabling
MSI to this chipset revision.  Also enable the short transfer quirk,
since it's likely this revision also has that quirk, and it should be
harmless to enable.

USB: OHCI: workaround for hardware bug: retired TDs not added to the Done Queue

2012-12-17T19:07:21+00:00

commit 50ce5c0683aa83eb161624ea89daa5a9eee0c2ce upstream.

This patch (as1636) is a partial workaround for a hardware bug
affecting OHCI controllers by NVIDIA at least, maybe others too.  When
the controller retires a Transfer Descriptor, it is supposed to add
the TD onto the Done Queue.  But sometimes this doesn't happen, with
the result that ohci-hcd never realizes the corresponding transfer has
finished.  Symptoms can vary; a typical result is that USB audio stops
working after a while.

The patch works around the problem by recognizing that TDs are always
processed in order.  Therefore, if a later TD is found on the Done
Queue than all the earlier TDs for the same endpoint must be finished
as well.

Unfortunately this won't solve the problem in cases where the missing
TD is the last one in the endpoint's queue.  A complete fix would
require a signficant amount of change to the driver.

USB: mark uas driver as BROKEN

2012-12-17T19:07:16+00:00

commit fb37ef98015f864d22be223a0e0d93547cd1d4ef upstream.

As reported https://bugzilla.kernel.org/show_bug.cgi?id=51031, the UAS
driver causes problems and has been asked to be not built into any of
the major distributions.  To prevent users from running into problems
with it, and for distros that were not notified, just mark the whole
thing as broken.

usb: ftdi_sio: fixup BeagleBone A5+ quirk

2012-12-17T19:06:54+00:00

commit 1a88d5eee2ef2ad1d3c4e32043e9c4c5347d4fc1 upstream.

BeagleBone A5+ devices ended up getting shipped with the
'BeagleBone/XDS100V2' product string, and not XDS100 like it
was agreed, so adjust the quirk to match.

USB: ftdi_sio: Add support for Newport AGILIS motor drivers

2012-12-17T19:06:53+00:00

commit d7e14b375b40c04cd735b115713043b69a2c68ac upstream.

The Newport AGILIS model AG-UC8 compact piezo motor controller
(http://search.newport.com/?q=*&x2=sku&q2=AG-UC8)
is yet another device using an FTDI USB-to-serial chip. It works
fine with the ftdi_sio driver when adding

  options ftdi-sio product=0x3000 vendor=0x104d

to modprobe.d. udevadm reports "Newport" as the manufacturer,
and "Agilis" as the product name.

USB: option: blacklist network interface on Huawei E173

2012-12-17T19:06:53+00:00

commit f36446cf9bbebaa03a80d95cfeeafbaf68218249 upstream.

The Huawei E173 will normally appear as 12d1:1436 in Linux.  But
the modem has another mode with different device ID and a slightly
different set of descriptors. This is the mode used by Windows like
this:

  3Modem:      USB\VID_12D1&PID_140C&MI_00\6&3A1D2012&0&0000
  Networkcard: USB\VID_12D1&PID_140C&MI_01\6&3A1D2012&0&0001
  Appli.Inter: USB\VID_12D1&PID_140C&MI_02\6&3A1D2012&0&0002
  PC UI Inter: USB\VID_12D1&PID_140C&MI_03\6&3A1D2012&0&0003

All interfaces have the same ff/ff/ff class codes in this mode.
Blacklisting the network interface to allow it to be picked up by
the network driver.
