net: usb: Fix memory leak on Tx data path

2012-11-17T21:18:52+00:00

[ Upstream commit 39707c2a3ba5011038b363f84d37c8a98d2d9db1 ]

Driver anchors the tx urbs and defers the urb submission if
a transmit request comes when the interface is suspended.
Anchoring urb increments the urb reference count. These
deferred urbs are later accessed by calling usb_get_from_anchor()
for submission during interface resume. usb_get_from_anchor()
unanchors the urb but urb reference count remains same.
This causes the urb reference count to remain non-zero
after usb_free_urb() gets called and urb never gets freed.
Hence call usb_put_urb() after anchoring the urb to properly
balance the reference count for these deferred urbs. Also,
unanchor these deferred urbs during disconnect, to free them
up.

qmi_wwan/cdc_ether: move Novatel 551 and E362 to qmi_wwan

2012-10-31T17:10:20+00:00

commit f8295ec22cb0f1ee6849b862addbfa3ea9320755 upstream.

These devices provide QMI and ethernet functionality via a standard CDC
ethernet descriptor.  But when driven by cdc_ether, the QMI
functionality is unavailable because only cdc_ether can claim the USB
interface.  Thus blacklist the devices in cdc_ether and add their IDs to
qmi_wwan, which enables both QMI and ethernet simultaneously.

mcs7830: Fix link state detection

2012-10-21T16:32:42+00:00

commit dabdaf0caa3af520dbc1df87b2fb4e77224037bd upstream.

The device had an undocumented "feature": it can provide a sequence of
spurious link-down status data even if the link is up all the time.
A sequence of 10 was seen so update the link state only after the device
reports the same link state 20 times.

smsc75xx: fix resume after device reset

2012-09-27T21:59:30+00:00

On some systems this device fails to properly resume after suspend,
this patch fixes it by running the usbnet_resume handler.

I suspect this also fixes this bug:

net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200

2012-09-20T21:54:28+00:00

One of the modes of Huawei E367 has this QMI/wwan interface:

 I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none)
 E:  Ad=83(I) Atr=03(Int.) MxPS=  64 Ivl=2ms
 E:  Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
 E:  Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=4ms

Huawei use subclass and protocol to identify vendor specific
functions, so adding a new vendor rule for this combination.

The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use
the same subclass to identify the QMI/wwan function.  Replace the
existing device specific UML290 entries with generic vendor matching,
adding support for the Pantech P4200.

The ZTE MF683 has 6 vendor specific interfaces, all using
ff/ff/ff for cls/sub/prot.  Adding a match on interface #5 which
is a QMI/wwan interface.

net: qmi_wwan: call subdriver with control intf only

2012-09-13T20:11:51+00:00

This fixes a hang on suspend due to calling wdm_suspend on
the unregistered data interface. The hang should have been
a NULL pointer reference had it not been for a logic error
in the cdc_wdm code.

  commit 230718bd net: qmi_wwan: bind to both control and data interface

changed qmi_wwan to use cdc_wdm as a subdriver for devices with
a two-interface QMI/wwan function.  The commit failed to update
qmi_wwan_suspend and qmi_wwan_resume, which were written to handle
either a single combined interface function, or no subdriver at all.

The result was that we called into the subdriver both when the
control interface was suspended and when the data interface was
suspended.  Calling the subdriver suspend function with an
unregistered interface is not supported and will make the
subdriver bug out.

net: qmi_wwan: fix Gobi device probing for un2430

2012-09-11T05:09:58+00:00

HP un2430 is a Gobi 3000 device. It was mistakenly treated as Gobi 1000
in patch b9f90eb2740203ff2592efe640409ad48335d1c2.

I own this device and qmi_wwan works again with this fix.

sierra_net: Endianess bug fix.

2012-09-10T19:05:42+00:00

I discovered I couldn't get sierra_net to work on a powerpc.  Turns out
the firmware attribute check assumes the system is little endian and
hence fails because the attributes is a 16 bit value.
