HID: wacom: Correct base usage for capacitive ExpressKey status bits

2021-07-14T14:59:28+00:00

[ Upstream commit 424d8237945c6c448c8b3f23885d464fb5685c97 ]

The capacitive status of ExpressKeys is reported with usages beginning
at 0x940, not 0x950. Bring our driver into alignment with reality.

HID: sony: fix freeze when inserting ghlive ps3/wii dongles

2021-07-14T14:59:26+00:00

[ Upstream commit fb1a79a6b6e1223ddb18f12aa35e36f832da2290 ]

This commit fixes a freeze on insertion of a Guitar Hero Live PS3/WiiU
USB dongle. Indeed, with the current implementation, inserting one of
those USB dongles will lead to a hard freeze. I apologize for not
catching this earlier, it didn't occur on my old laptop.

While the issue was isolated to memory alloc/free, I could not figure
out why it causes a freeze. So this patch fixes this issue by
simplifying memory allocation and usage.

We remind that for the dongle to work properly, a control URB needs to
be sent periodically. We used to alloc/free the URB each time this URB
needed to be sent.

With this patch, the memory for the URB is allocated on the probe, reused
for as long as the dongle is plugged in, and freed once the dongle is
unplugged.

HID: hid-input: add Surface Go battery quirk

2021-07-14T14:59:26+00:00

[ Upstream commit b5539722eb832441f309642fe5102cc3536f92b8 ]

The Elantech touchscreen/digitizer in the Surface Go mistakenly reports
having a battery. This results in a low battery message every time you
try to use the pen.

This patch adds a quirk to ignore the non-existent battery and
gets rid of the false low battery messages.

HID: do not use down_interruptible() when unbinding devices

2021-07-14T14:59:23+00:00

[ Upstream commit f2145f8dc566c4f3b5a8deb58dcd12bed4e20194 ]

Action of unbinding driver from a device is not cancellable and should not
fail, and driver core does not pay attention to the result of "remove"
method, therefore using down_interruptible() in hid_device_remove() does
not make sense.

correct modalias for automatic loading of this driver when it is built
as an external module.

HID: multitouch: Disable event reporting on suspend on the Asus T101HA touchpad

2021-06-18T08:02:49+00:00

[ Upstream commit 31a4cf1d223dc6144d2e7c679cc3a98f84a1607b ]

The Asus T101HA has a problem with spurious wakeups when the lid is
closed, this is caused by the screen sitting so close to the touchpad
that the touchpad ends up reporting touch events, causing these wakeups.

Add a quirk which disables event reporting on suspend when set, and
enable this quirk for the Asus T101HA touchpad fixing the spurious
wakeups, while still allowing the device to be woken by pressing a
key on the keyboard (which is part of the same USB device).

HID: usbhid: fix info leak in hid_submit_ctrl

2021-06-18T08:02:48+00:00

[ Upstream commit 6be388f4a35d2ce5ef7dbf635a8964a5da7f799f ]

In hid_submit_ctrl(), the way of calculating the report length doesn't
take into account that report->size can be zero. When running the
syzkaller reproducer, a report of size 0 causes hid_submit_ctrl) to
calculate transfer_buffer_length as 16384. When this urb is passed to
the usb core layer, KMSAN reports an info leak of 16384 bytes.

To fix this, first modify hid_report_len() to account for the zero
report size case by using DIV_ROUND_UP for the division. Then, call it
from hid_submit_ctrl().
