USB: kaweth.c: use GFP_ATOMIC under spin_lock

2014-02-10T21:11:23+00:00

commit e4c7f259c5be99dcfc3d98f913590663b0305bf8 upstream.

The problem is that we call this with a spin lock held.  The call tree
is:
	kaweth_start_xmit() holds kaweth->device_lock.
	-> kaweth_async_set_rx_mode()
	   -> kaweth_control()
	      -> kaweth_internal_control_msg()

The kaweth_internal_control_msg() function is only called from
kaweth_control() which used GFP_ATOMIC for its allocations.

NET: cdc-phonet, handle empty phonet header

2012-03-14T14:57:10+00:00

commit 468c3f924f043cad7a04f4f4d5224a2c9bc886c1 upstream.

Currently, for N 5800 XM I get:
cdc_phonet: probe of 1-6:1.10 failed with error -22

It's because phonet_header is empty. Extra altsetting looks like
there:
E 05 24 00 01 10 03 24 ab 05 24 06 0a 0b 04 24 fd  .$....$..$....$.
E 00                                               .

I don't see the header used anywhere so just check if the phonet
descriptor is there, not the structure itself.

drivers/net/usb/hso.c: prevent reading uninitialized memory

2011-01-06T23:07:58+00:00

commit 7011e660938fc44ed86319c18a5954e95a82ab3e upstream.

Fixed formatting (tabs and line breaks).

The TIOCGICOUNT device ioctl allows unprivileged users to read
uninitialized stack memory, because the "reserved" member of the
serial_icounter_struct struct declared on the stack in hso_get_count()
is not altered or zeroed before being copied back to the user.  This
patch takes care of it.

usbnet: Set parent device early for netdev_printk()

2010-08-02T17:29:20+00:00

[ Upsteam commit 0dacca73a3ddefa6cb8a7e0282f938e01faa1a64 ]

netdev_printk() follows the net_device's parent device pointer, so
we must set that earlier than we previously did.

pegasus: fix USB device ID for ETX-US2

[ Upstream commit 95718c1c25370b2c85061a4d8dfab2831b3ad280 ]

USB device ID definition for I-O Data ETX-US2 is wrong.
Correct ID is 0x093a. Here's snippet from /proc/bus/usb/devices;

This patch enables pegasus driver to work fine with ETX-US2.

dm9601: fix phy/eeprom write routine

2010-05-03T22:26:30+00:00

Use correct bit positions in DM_SHARED_CTRL register for writes.

Michael Planes recently encountered a 'KY-RS9600 USB-LAN converter', which
came with a driver CD containing a Linux driver. This driver turns out to
be a copy of dm9601.c with symbols renamed and my copyright stripped.
That aside, it did contain 1 functional change in dm_write_shared_word(),
and after checking the datasheet the original value was indeed wrong
(read versus write bits).

On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s.
On other devices the difference is less spectacular, but still significant
(~30%).

net/usb: initiate sync sequence in sierra_net.c driver

2010-05-02T01:07:46+00:00

The following patch adds the initiation of the sync sequence to
"sierra_net_bind()". If this step is omitted, the modem will never sync up
with the host and it will not be possible to establish a data connection.

net/usb: add sierra_net.c driver

2010-04-28T01:12:04+00:00

Re-submitted based on comments from netdev community.
Summary of the changes:
1. Improved error handling.
2. Added the missing timeout arguments to usb_control_msg().

The following is a new Linux driver which exposes certain models of Sierra
Wireless modems to the operating system as Network Interface Cards (NICs).

This driver requires a version of the sierra.c driver which supports
blacklisting to work properly. The blacklist in sierra.c rejects the interfaces
claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts
(i.e. whitelists) the interface(s) used for USB-to-WWAN traffic.
The version of sierra.c which supports blacklisting is
available from the sierra wireless knowledge base page for older kernels. It is
also available in Linux kernel starting from version 2.6.31.

This driver works with all Sierra Wireless devices configured with PID=68A3
like USB305, USB306 provided the corresponding firmware version is I2.0
(for USB305) or M3.0 (for USB306) and later.
This driver will not work with earlier firmware versions than the ones shown
above. In this case the driver will issue an error message indicating
incompatibility and will not serve the device's USB-to-WWAN interface.

Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c.
A series of hook functions are provided in sierra_net.c which are called by
usbnet.c in response to a particular condition such as receipt or transmission
of a data packet. As such, usbnet.c does most of the work of making
a modem appear to the system as a network device and for properly exchanging
traffic between the USB subsystem and the Network card interface.
Sierra_net.c is concerned with managing the data exchanged between the
USB-to-WWAN interface and the upper layers of the operating system.
