[ Upstream commit 8ae2f2b0a2 ]
When a reset notify IPC message is received, the ISR schedules a work
function and passes the ISHTP device to it via a global pointer
ishtp_dev. If ish_probe() fails, the devm-managed device resources
including ishtp_dev are freed, but the work is not cancelled, causing a
use-after-free when the work function tries to access ishtp_dev. Use
devm_work_autocancel() instead, so that the work is automatically
cancelled if probe fails.

commit 1c5d422124 upstream.
The default maximum data buffer size for this interface is UHID_DATA_MAX

when ensuring the sanity, rather than a value between the user provided
value and HID_MAX_BUFFER_SIZE (16k).

commit b1a37ed00d upstream.
Presently, when a report is processed, its proposed size, provided by
the user of the API (as Report Size * Report Count) is compared against
the subsystem default HID_MAX_BUFFER_SIZE (16k). However, some
low-level HID drivers allocate a reduced amount of memory to their
buffers (e.g. UHID only allocates UHID_DATA_MAX (4k) buffers), rending
this check inadequate in some cases.
In these circumstances, if the received report ends up being smaller
than the proposed report size, the remainder of the buffer is zeroed.
That is, the space between sizeof(csize) (size of the current report)
and the rsize (size proposed i.e. Report Size * Report Count), which can
be handled up to HID_MAX_BUFFER_SIZE (16k). Meaning that memset()
shoots straight past the end of the buffer boundary and starts zeroing
out in-use values, often resulting in calamity.
This patch introduces a new variable into 'struct hid_ll_driver' where
individual low-level drivers can over-ride the default maximum value of
HID_MAX_BUFFER_SIZE (16k) with something more sympathetic to the
interface.

In certain circumstances, such as when creating I2C-connected HID

The source of such quirks may be device tree, or DMI data, or something
else not readily available to the HID core itself and therefore cannot
be reconstructed easily. To allow this, introduce "initial_quirks" field
in hid_device structure and use it when determining the final set of
quirks.
This fixes the problem with i2c-hid setting up device-tree sourced
quirks too late and losing them on device rebind, and also allows to
sever the tie between hid-code and i2c-hid when applying DMI-based
quirks.

Quote from previous patch by Maxim Mikityanskiy
Plantronics Blackwire 3220 Series (047f:c056) sends HID reports twice
for each volume key press. This patch adds a quirk to hid-plantronics
for this product ID, which will ignore the second volume key press if
it happens within 5 ms from the last one that was handled.
The patch was tested on the mentioned model only, it shouldn't affect
other models, however, this quirk might be needed for them too.
Auto-repeat (when a key is held pressed) is not affected, because the
rate is about 3 times per second, which is far less frequent than once
in 5 ms.

commit 67c90d1401 upstream.
The MCP2221 driver should not connect to the hidraw userspace interface,
as it needs exclusive access to the chip.
If you want to use /dev/hidrawX with the MCP2221, you need to avoid
binding this driver to the device and use the hid generic driver instead
(e.g. using udev rules).

commit 1db1f39259 upstream.
Some Wacom devices have a special "bootloader" mode that is used for
firmware flashing. When operating in this mode, the device cannot be
used for input, and the HID descriptor is not able to be processed by
the driver. The driver generates an "Unknown device_type" warning and
then returns an error code from wacom_probe(). This is a problem because
userspace still needs to be able to interact with the device via hidraw
to perform the firmware flash.
This commit adds a non-generic device definition for 056a:0094 which
is used when devices are in "bootloader" mode. It marks the devices
with a special BOOTLOADER type that is recognized by wacom_probe() and
wacom_raw_event(). When we see this type we ensure a hidraw device is
created and otherwise keep our hands off so that userspace is in full
control.

[ Upstream commit f9ce4db0ec ]
The XP-PEN Deco LW is a UGEE v2 device with a frame with 8 buttons.
Its pen has 2 buttons, supports tilt and pressure.
It can be connected by USB cable or using a USB Bluetooth dongle to use
it in wireless mode. When it is connected using the dongle, the device
battery is used to power it.
Its vendor, product and version are identical to the Deco L. The only
difference reported by its firmware is the product name.
In order to add support for battery reporting, add a new HID descriptor
and a quirk to detect the wireless version of the tablet.

[ Upstream commit 037c1aaeb9 ]
The XP-PEN Deco LW drawing tablet can be connected by USB cable or using
a USB Bluetooth dongle. When it is connected using the dongle, there
might be a small delay until the tablet is paired with the dongle.
Fetching the device battery during this delay results in random battery
percentage values.
Add a quirk to avoid actively querying the battery percentage and wait
for the device to report it on its own.

[ Upstream commit 084bc074c2 ]
The iso_layout parameter must be manually set to get the driver to
swap KEY_102ND and KEY_GRAVE. This patch eliminates the need to do that.
This is safe to do, as Macs with keyboards that do not need the quirk
will keep working the same way as the value of hid->country will be
different than HID_COUNTRY_INTERNATIONAL_ISO. This was tested by one
person with a Mac with the WELLSPRINGT2_J152F keyboard with a layout
that does not require the quirk to be set.

[ Upstream commit 5476fcf7f7 ]
The hid-apple driver does not support chaining translations or
dependencies on other translations. This creates two problems:
1 - In Non-English keyboards of Macs, KEY_102ND and KEY_GRAVE are
swapped and the APPLE_ISO_TILDE_QUIRK is used to work around this
problem. The quirk is not set for the Macs where these bugs happen yet
(see the 2nd patch for that), but this can be forced by setting the
iso_layout parameter. Unfortunately, this only partially works.
KEY_102ND gets translated to KEY_GRAVE, but KEY_GRAVE does not get
translated to KEY_102ND, so both of them end up functioning as
KEY_GRAVE. This is because the driver translates the keys as if Fn was
pressed and the original is sent if it is not pressed, without any
further translations happening on the key[#463]. KEY_GRAVE is present at
macbookpro_no_esc_fn_keys[#195], so this is what happens:
- KEY_GRAVE -> KEY_ESC (as if Fn is pressed)
- KEY_GRAVE is returned (Fn isn't pressed, so translation is discarded)
- KEY_GRAVE -> KEY_102ND (this part is not reached!)
...
2 - In case the touchbar does not work, the driver supports sending
Escape when Fn+KEY_GRAVE is pressed. As mentioned previously, KEY_102ND
is actually KEY_GRAVE and needs to be translated before this happens.
Normally, these are the steps that should happen:
- KEY_102ND -> KEY_GRAVE
- KEY_GRAVE -> KEY_ESC (Fn is pressed)
- KEY_ESC is returned
Though this is what happens instead, as dependencies on other
translations are not supported:
- KEY_102ND -> KEY_ESC (Fn is pressed)
- KEY_ESC is returned
This patch fixes both bugs by ordering the translations correctly and by
making the translations continue and not return immediately after
translating a key so that chained translations work and translations can
depend on other ones.
This patch also simplifies the implementation of the swap_fn_leftctrl
option a little bit, as it makes it simply use a normal translation
instead adding extra code to translate a key to KEY_FN[#381]. This change
wasn't put in another patch as the code that translates the Fn key needs
to be changed because of the changes in the patch, and those changes
would be discarded with the next patch anyway (the part that originally
translates KEY_FN to KEY_LEFTCTRL needs to be made an else-if branch of
the part that transltes KEY_LEFTCTRL to KEY_FN).
Note: Line numbers (#XYZ) are for drivers/hid/hid-apple.c at commit
20afcc4625 ("HID: apple: Add "GANSS" to the non-Apple list").
Note: These bugs are only present on Macs with a keyboard with no
dedicated escape key and a non-English layout.

The motivation for this patch is that:
hid_sensor_custom_field.attr_name and
hid_sensor_custom_field.attrs
has the size of HID_CUSTOM_TOTAL_ATTRS and used in same context.
We compare against HID_CUSTOM_TOTAL_ATTRS when

[ Upstream commit 9984fbf55b ]
HID-RMI is special in the sense that it does not carry HID events
directly, but rather uses HID protocol as a wrapper/transport for RMI
protocol. Therefore we should not assume that all data coming from the
device via interrupt is associated with user activity and report wakeup
event indiscriminately, but rather let HID-RMI do that when appropriate.
HID-RMI devices tag responses to the commands issued by the host as
RMI_READ_DATA_REPORT_ID whereas motion and other input events from the
device are tagged as RMI_ATTN_REPORT_ID. Change hid-rmi to report wakeup
events when receiving the latter packets. This allows ChromeOS to
accurately identify wakeup source and make correct decision on the mode
of the resume the system should take ("dark" where the display stays off
vs normal one).

This reverts commit 532223c8ac.
As reported in [0], hid-logitech-hidpp now binds on all bluetooth mice,
but there are corner cases where hid-logitech-hidpp just gives up on
the mouse. This leads the end user with a dead mouse.
Given that we are at -rc8, we are definitively too late to find a proper
fix. We already identified 2 issues less than 24 hours after the bug
report. One in that ->match() was never designed to be used anywhere else
than in hid-generic, and the other that hid-logitech-hidpp has corner
cases where it gives up on devices it is not supposed to.
So we have no choice but postpone this patch to the next kernel release.

This reverts commit 8544c812e4.
We need to revert commit 532223c8ac ("HID: logitech-hidpp: Enable HID++
for all the Logitech Bluetooth devices") because that commit might make
hid-logitech-hidpp bind on mice that are not well enough supported by
hid-logitech-hidpp, and the end result is that the probe of those mice
is now returning -ENODEV, leaving the end user with a dead mouse.
Given that commit 8544c812e4 ("HID: logitech-hidpp: Remove special-casing
of Bluetooth devices") is a direct dependency of 532223c8ac, revert it
too.
Note that this also adapt according to commit 908d325e16 ("HID:
logitech-hidpp: Detect hi-res scrolling support") to re-add support of
the devices that were removed from that commit too.
I have locally an MX Master and I tested this device with that revert,
ensuring we still have high-res scrolling.
