2b2bcc76e2 HID: surface-hid: Fix get-report request
Getting a report (e.g. feature report) from a device requires us to send
a request indicating which report we want to retrieve and then waiting
for the corresponding response containing that report. We already
provide the response structure to the request call, but the request
isn't marked as a request that expects a response. Thus the request
returns before we receive the response and the response buffer indicates
a zero length response due to that.

This essentially means that the get-report calls are broken and will
always indicate that a report of length zero has been read.

Fix this by appropriately marking the request.

fb1a79a6b6 HID: sony: fix freeze when inserting ghlive ps3/wii dongles
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.

Different platforms have different DMA capability, on most of
platforms, DMA support cache snooping. But few platforms,
such as ElkhartLake (EHL), don't support cache snooping
which requires cache flush from driver.

So add a hardware level callback to let ishtp driver know if cache
flush is needed.

As most of platform support cache snooping, so driver will not
do cache flush by default, until platform implements this callback
and return true explicitly.

There is no need to use a quirk and then return -ENODEV from the

The hid-multitouch hiddev has a group of HID_GROUP_MULTITOUCH_WIN_8,

ca66a6770b HID: i2c-hid: Skip ELAN power-on command after reset
For ELAN touchscreen, we found our boot code of IC was not flexible enough
to receive and handle this command.
Once the FW main code of our controller is crashed for some reason,
the controller could not be enumerated successfully to be recognized
by the system host. therefore, it lost touch functionality.

Add quirk for skip send power-on command after reset.
It will impact to ELAN touchscreen and touchpad on HID over I2C projects.

Fixes: 43b7029f47 ("HID: i2c-hid: Send power-on command after reset").

6be388f4a3 HID: usbhid: fix info leak in hid_submit_ctrl
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().

This effectively changes collection_is_mt from

to

Some devices erroneously report Pen for fingers, and Win8 stylus-on-touchscreen
devices report contact ID, but mark the accompanying touchscreen device's
collection correctly

presses such as Fn+Pause. The device in this case is emitting
two events on key down, and 3 on key up, the third key up event
is report ID 0x02 and is unfiltered, causing incorrect event.

This patch filters out the single problematic event.
