USB: option: add XS Stick W100-2 from 4G Systems

2015-12-09T19:31:24+00:00

commit 638148e20c7f8f6e95017fdc13bce8549a6925e0 upstream.

Thomas reports
"
4gsystems sells two total different LTE-surfsticks under the same name.
..
The newer version of XS Stick W100 is from "omega"
..
Under windows the driver switches to the same ID, and uses MI03\6 for
network and MI01\6 for modem.

Now all important things are there:

There is also ttyUSB0, but it is not usable, at least not for at.

The device works well with qmi and ModemManager-NetworkManager.

USB: serial: option: add support for Novatel MiFi USB620L

2015-12-09T19:31:24+00:00

commit e07af133c3e2716db25e3e1e1d9f10c2088e9c1a upstream.

Also known as Verizon U620L.

The device is modeswitched from 1410:9020 to 1410:9022 by selecting the
4th USB configuration:

 $ sudo usb_modeswitch –v 0x1410 –p 0x9020 –u 4

This configuration provides a ECM interface as well as TTYs ('Enterprise
Mode' according to the U620 Linux integration guide).

USB: qcserial: Fix support for HP lt4112 LTE/HSPA+ Gobi 4G Modem

2015-12-09T19:31:23+00:00

commit 59536da34513c594af2a6fd35ba65ea45b6960a1 upstream.

The DEVICE_HWI type was added under the faulty assumption that Huawei
devices based on Qualcomm chipsets and firmware use the static USB
interface numbering known from Gobi devices.  But this model does
not apply to Huawei devices like the HP branded lt4112 (Huawei me906e).
Huawei firmwares will dynamically assign interface numbers. Functions
are renumbered when the firmware is reconfigured.

Fix by changing the DEVICE_HWI type to use a simplified version
of Huawei's subclass + protocol scheme: Blacklisting known network
interface combinations and assuming the rest are serial.

USB: qcserial: Add support for Quectel EC20 Mini PCIe module

commit 9d5b5ed796d7afd7e8d2ac4b4fb77c6a49463f4b upstream.

It seems like this device has same vendor and product IDs as G2K
devices, but it has different number of interfaces(4 vs 5) and also
different interface layout which makes it currently unusable:

USB: whiteheat: fix potential null-deref at probe

2015-10-22T21:49:26+00:00

commit cbb4be652d374f64661137756b8f357a1827d6a4 upstream.

Fix potential null-pointer dereference at probe by making sure that the
required endpoints are present.

The whiteheat driver assumes there are at least five pairs of bulk
endpoints, of which the final pair is used for the "command port". An
attempt to bind to an interface with fewer bulk endpoints would
currently lead to an oops.

Fixes CVE-2015-5257.

USB: pl2303: fix baud-rate divisor calculations

2015-09-21T17:10:51+00:00

commit 49bda21266fdf195142e8b5dea057f09e96ada9f upstream.

This commit fixes the following issues:

1. The 9th bit of buf was believed to be the LSB of divisor's
exponent, but the hardware interprets it as MSB (9th bit) of the
mantissa. The exponent is actually one bit shorter and applies
to base 4, not 2 as previously believed.

2. Loop iterations doubled the exponent instead of incrementing.

3. The exponent wasn't checked for overflow.

4. The function returned requested rate instead of actual rate.

Due to issue #2, the old code deviated from the wrong formula
described in #1 and actually yielded correct rates when divisor
was lower than 4096 by using exponents of 0, 2 or 4 base-2,
interpreted as 0, 1, 2 base-4 with the 9th mantissa bit clear.
However, at 93.75 kbaud or less the rate turned out too slow
due to #2 or too fast due to #2 and #3.

I tested this patch by sending and validating 0x00,0x01,..,0xff
to an FTDI dongle at 234, 987, 2401, 9601, 31415, 115199, 250k,
500k, 750k, 1M, 1.5M, 3M+1 baud. All rates passed.

I also used pv to check speed at some rates unsupported by FTDI:
45 (the lowest possible), 2M, 4M, 5M and 6M-1. Looked sane.
