Position 64(Logical Maximum) and 70(Usage Maximum) are 101.
Both should be 0xE7 to support JIS specific keys(ろ, Eisu, Kana, |) support.
position 117 is also 101 but not related(it is Usage 65h).

There are no difference of product id between JIS and ANSI.
They are same 0x0267.

commit 1e4ce418b1cb1a810256b5fb3fd33d22d1325993 upstream.

Syzbot reported slab-out-of-bounds Write bug in hid-betopff driver.
The problem is the driver assumes the device must have an input report but
some malicious devices violate this assumption.

So this patch checks hid_device's input is non empty before it's been used.

Since the actual_length calculation is performed unsigned, packets
shorter than 7 bytes (e.g. packets without data or otherwise truncated)
or non-received packets ("zero" bytes) can cause buffer overflow.

[ Upstream commit 786537063bbfb3a7ebc6fc21b2baf37fb91df401 ]

A quirk was recently added for Elan devices that has same device match
as an entry earlier in the list. The i2c_hid_lookup_quirk function will
always return the last match in the list, so the new entry shadows the
old entry. The quirk in the previous entry, I2C_HID_QUIRK_BOGUS_IRQ,
silenced a flood of messages which have reappeared in the 5.13 kernel.

This change moves the two quirk flags into the same entry.

70fd936367 HID: input: do not report stylus battery state as "full"
[ Upstream commit f4abaa9eebde334045ed6ac4e564d050f1df3013 ]

The power supply states of discharging, charging, full, etc, represent
state of charging, not the capacity level of the battery (for which
we have a separate property). Current HID usage tables to not allow
for expressing charging state of the batteries found in generic
styli, so we should simply assume that the battery is discharging
even if current capacity is at 100% when battery strength reporting
is done via HID interface. In fact, we were doing just that before
commit 581c4484769e.

This change helps UIs to not mis-represent fully charged batteries in
styli as being charging/topping-off.

cb71730a63 HID: wacom: Re-enable touch by default for Cintiq 24HDT / 27QHDT
commit 6ca2350e11f09d5d3e53777d1eff8ff6d300ed93 upstream.

Commit 670e90924bfe ("HID: wacom: support named keys on older devices")
added support for sending named events from the soft buttons on the
24HDT and 27QHDT. In the process, however, it inadvertantly disabled the
touchscreen of the 24HDT and 27QHDT by default. The
`wacom_set_shared_values` function would normally enable touch by default
but because it checks the state of the non-shared `has_mute_touch_switch`
flag and `wacom_setup_touch_input_capabilities` sets the state of the
/shared/ version, touch ends up being disabled by default.

This patch sets the non-shared flag, letting `wacom_set_shared_values`
take care of copying the value over to the shared version and setting
the default touch state to "on".

b1e3596416 HID: usbhid: fix info leak in hid_submit_ctrl
[ 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().

the Game Controls page, which is not recognized by the generic HID

the second axis get mapped to ABS_MISC+1, and therefore made available

a5e554f789 HID: i2c-hid: Skip ELAN power-on command after reset
commit ca66a6770bd9d6d99e469debd1c7363ac455daf9 upstream.

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.

[ Upstream commit 617103246cfd19af837e4cb614ba9f877c4f7779 ]

Mapping the mic-mute button to KEY_MICMUTE is technically correct but
KEY_MICMUTE translates to a scancode of 256 (248 + 8) under X,
which does not fit in 8 bits, so it does not work.

Because of this userspace is expecting KEY_F20 instead,
theoretically KEY_MICMUTE should work under Wayland but even
there it does not work, because the desktop-environment is
listening only for KEY_F20 and not for KEY_MICMUTE.

[ Upstream commit 34348a8661e3cd67dcf6938f08c8bb77522301f7 ]

The HID lenovo probe function only attaches drvdata to one of the
USB interfaces, but lenovo_event() will get called for all USB interfaces
to which hid-lenovo is bound.

This allows a malicious device to fake being a device handled by
hid-lenovo, which generates events for which lenovo_event() has
special handling (and thus dereferences hid_get_drvdata()) on another
interface triggering a NULL pointer exception.

Add a check for hid_get_drvdata() returning NULL, avoiding this
possible NULL pointer exception.

2. Actually propagate errors to the caller.

3. Since the LEDs are part of an USB keyboard-dock the mute LEDs can go

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.

[ Upstream commit fab3a95654eea01d6b0204995be8b7492a00d001 ]

This new connection type is the new iteration of the Lightspeed
connection and will probably be used in some of the newer gaming
devices. It is currently use in the G Pro X Superlight.

This patch should be backported to older versions, as currently the
driver will panic when seing the unsupported connection. This isn't
an issue when using the receiver that came with the device, as Logitech
has been using different PIDs when they change the connection type, but
is an issue when using a generic receiver (well, generic Lightspeed
receiver), which is the case of the one in the Powerplay mat. Currently,
the only generic Ligthspeed receiver we support, and the only one that
exists AFAIK, is ther Powerplay.

As it stands, the driver will panic when seeing a G Pro X Superlight
connected to the Powerplay receiver and won't send any input events to
userspace! The kernel will warn about this so the issue should be easy
to identify, but it is still very worrying how hard it will fail :(

923a82a6bc HID: wacom: Ignore attempts to overwrite the touch_max value from HID
commit 88f38846bfb1a452a3d47e38aeab20a4ceb74294 upstream.

The `wacom_feature_mapping` function is careful to only set the the
touch_max value a single time, but this care does not extend to the
`wacom_wac_finger_event` function. In particular, if a device sends
multiple HID_DG_CONTACTMAX items in a single feature report, the
driver will end up retaining the value of last item.

The HID descriptor for the Cintiq Companion 2 does exactly this. It
incorrectly sets a "Report Count" of 2, which will cause the driver
to process two HID_DG_CONTACTCOUNT items. The first item has the actual
count, while the second item should have been declared as a constant
zero. The constant zero is the value the driver ends up using, however,
since it is the last HID_DG_CONTACTCOUNT in the report.

    Report ID (16),
    Usage (Contact Count Maximum),  ; Contact count maximum (55h, static value)
    Report Count (2),
    Logical Maximum (10),
    Feature (Variable),

To address this, we add a check that the touch_max is not already set
within the `wacom_wac_finger_event` function that processes the
HID_DG_TOUCHMAX item. We emit a warning if the value is set and ignore
the updated value.

This could potentially cause problems if there is a tablet which has
a similar issue but requires the last item to be used. This is unlikely,
however, since it would have to have a different non-zero value for
HID_DG_CONTACTMAX earlier in the same report, which makes no sense
except in the case of a firmware bug. Note that cases where the
HID_DG_CONTACTMAX items are in different reports is already handled
(and similarly ignored) by `wacom_feature_mapping` as mentioned above.

during testing and it seems the keyboard events were actually not being
sent to userspace.
This resulted in keyboard events being broken in userspace, please
backport the fix.

The receiver uses the normal 0x01 Logitech keyboard report descriptor,
as expected, so it is just a matter of flagging it as supported.

Prevent invalid (0, 0) inputs to hid-core's snto32() function.

Maybe it is just the dummy device here that is causing this, but
there are hundreds of calls to snto32(0, 0). Having n (bits count)
of 0 is causing the current UBSAN trap with a shift value of
0xffffffff (-1, or n - 1 in this function).

Either of the value to shift being 0 or the bits count being 0 can be
handled by just returning 0 to the caller, avoiding the following
complex shift + OR operations:

	return value & (1 << (n - 1)) ? value | (~0U << n) : value;

77344e18cf HID: make arrays usage and value to be the same
commit ed9be64eefe26d7d8b0b5b9fa3ffdf425d87a01f upstream.

The HID subsystem allows an "HID report field" to have a different
number of "values" and "usages" when it is allocated. When a field
struct is created, the size of the usage array is guaranteed to be at
least as large as the values array, but it may be larger. This leads to
a potential out-of-bounds write in
__hidinput_change_resolution_multipliers() and an out-of-bounds read in
hidinput_count_leds().

To fix this, let's make sure that both the usage and value arrays are
the same size.

The commit changes the mt_class from MT_CLS_WIN_8 to
MT_CLS_WIN_8_FORCE_MULTI_INPUT, so MT_QUIRK_CONFIDENCE isn't applied
anymore.

So also apply the quirk since MT_CLS_WIN_8_FORCE_MULTI_INPUT is
essentially MT_CLS_WIN_8.

a7f6d4ab44 HID: wacom: Correct NULL dereference on AES pen proximity
commit 179e8e47c02a1950f1c556f2b854bdb2259078fb upstream.

The recent commit to fix a memory leak introduced an inadvertant NULL
pointer dereference. The `wacom_wac->pen_fifo` variable was never
intialized, resuling in a crash whenever functions tried to use it.
Since the FIFO is only used by AES pens (to buffer events from pen
proximity until the hardware reports the pen serial number) this would
have been easily overlooked without testing an AES device.

This patch converts `wacom_wac->pen_fifo` over to a pointer (since the
call to `devres_alloc` allocates memory for us) and ensures that we assign
it to point to the allocated and initalized `pen_fifo` before the function
returns.

0a3be22a90 HID: logitech-hidpp: Add product ID for MX Ergo in Bluetooth mode
[ Upstream commit 7de843dbaaa68aa514090e6226ed7c6374fd7e49 ]

The Logitech MX Ergo trackball supports HID++ 4.5 over Bluetooth. Add its
product ID to the table so we can get battery monitoring support.
(The hid-logitech-hidpp driver already recognizes it when connected via
a Unifying Receiver.)

797c128d3c HID: wacom: Fix memory leakage caused by kfifo_alloc
commit 37309f47e2f5674f3e86cb765312ace42cfcedf5 upstream.

As reported by syzbot below, kfifo_alloc'd memory would not be freed
if a non-zero return value is triggered in wacom_probe. This patch
creates and uses devm_kfifo_alloc to allocate and free itself.
