HID: multitouch: enable palm rejection for Windows Precision Touchpad

2016-07-27T15:42:15+00:00

commit 6dd2e27a103d716921cc4a1a96a9adc0a8e3ab57 upstream.

The usage Confidence is mandary to Windows Precision Touchpad devices. If
it is examined in input_mapping on a WIndows Precision Touchpad, a new add
quirk MT_QUIRK_CONFIDENCE desgned for such devices will be applied to the
device. A touch with the confidence bit is not set is determined as
invalid.

Tested on Dell XPS13 9343

Revert "HID: multitouch: enable palm rejection if device implements confidence usage"

2016-07-27T15:42:14+00:00

commit 62630ea768869beeb1e514b0bf5607a0c9b93d12 upstream.

This reverts commit 25a84db15b3f ("HID: multitouch: enable palm rejection
if device implements confidence usage")

The commit enables palm rejection for Win8 Precision Touchpad devices but
the quirk MT_QUIRK_VALID_IS_CONFIDENCE it is using is not working very
properly. This quirk is originally designed for some WIn7 touchscreens. Use
of this for a Win8 Precision Touchpad will cause unexpected pointer jumping
problem.

HID: hiddev: validate num_values for HIDIOCGUSAGES, HIDIOCSUSAGES commands

2016-07-27T15:42:14+00:00

commit 93a2001bdfd5376c3dc2158653034c20392d15c5 upstream.

This patch validates the num_values parameter from userland during the
HIDIOCGUSAGES and HIDIOCSUSAGES commands. Previously, if the report id was set
to HID_REPORT_ID_UNKNOWN, we would fail to validate the num_values parameter
leading to a heap overflow.

HID: elo: kill not flush the work

2016-07-27T15:42:14+00:00

commit ed596a4a88bd161f868ccba078557ee7ede8a6ef upstream.

Flushing a work that reschedules itself is not a sensible operation. It needs
to be killed. Failure to do so leads to a kernel panic in the timer code.

2016-05-03T10:03:44+00:00

Commit 7e12978 ("HID: wacom: break out wacom_intuos_get_tool_type") by accident
removed stylus_in_proximity flag for Intuos series while shuffling the code
around.

Fix that by reintroducing that flag setting in wacom_intuos_inout(), where
it originally was.

Needed for v2 of the device firmware, otherwise kernel will stuck for few

HID: wacom: Support switching from vendor-defined device mode on G9 and G11

2016-04-05T15:20:32+00:00

A tablet PC booted into Windows may have its pen/touch hardware switched
into "Wacom mode" similar to what we do with explicitly-supported hardware.
Some devices appear to maintain this state across reboots, preventing their
use with the generic HID driver. This patch adds support for detecting the
presence of the mode switch feature report used by devices based on the G9
and G11 chips and has the HID codepath always attempt to reset the device
back to sending standard HID reports.
