HID: multitouch: validate indexes details

2014-01-03T04:33:34+00:00

commit 8821f5dc187bdf16cfb32ef5aa8c3035273fa79a upstream.

When working on report indexes, always validate that they are in bounds.
Without this, a HID device could report a malicious feature report that
could trick the driver into a heap overflow:

[  634.885003] usb 1-1: New USB device found, idVendor=0596, idProduct=0500
...
[  676.469629] BUG kmalloc-192 (Tainted: G        W   ): Redzone overwritten

Note that we need to change the indexes from s8 to s16 as they can
be between -1 and 255.

CVE-2013-2897

[bwh: Backported to 3.2: mt_device::{cc,cc_value,inputmode}_index do not
 exist and the corresponding indices do not need to be validated.
 mt_device::maxcontact_report_id does not exist either.  So all we need
 to do is to widen mt_device::inputmode.]

HID: multitouch: support PixArt optical touch screen

commit b7ea95ff9baab144dacdc30d752307938c5ab6bf upstream.

This patch modifies hid-multitouch driver for supporting PixArt optical touch
screen.  Because of the device does not have to set initial report, we apply
"HID_QUIRK_NO_INIT_REPORTS" quirk and add the device into hid_blacklist[]
