[ 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 :(

Winpad A15
[ Upstream commit fc6a31b00739356809dd566e16f2c4325a63285d ]
The ITE8568 EC on the Voyo Winpad A15 presents itself as an I2C-HID
attached keyboard and mouse (which seems to never send any events).
This needs the I2C_HID_QUIRK_NO_IRQ_AFTER_RESET quirk, otherwise we get
the following errors:
[ 3688.770850] i2c_hid i2c-ITE8568:00: failed to reset device.
[ 3694.915865] i2c_hid i2c-ITE8568:00: failed to reset device.

[ 3708.236518] i2c_hid: probe of i2c-ITE8568:00 failed with error -61
Which leads to a significant boot delay.

[ Upstream commit 1008230f2abeb624f6d71b2e1c424fa4eeebbf84 ]
Mayflash/Dragonrise seems to have yet another device ID for one of their
Gamecube controller adapters. Previous to this commit, the adapter
registered only one /dev/input/js* device, and all controller inputs (from
any controller) were mapped to this device. This patch defines the 1846
USB device ID and enables the HID_QUIRK_MULTI_INPUT quirk for it, which
fixes that (with the patch, four /dev/input/js* devices are created, one
for each of the four controller ports).

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.

commit ef07c116d98772952807492bd32a61f5af172a94 upstream.
In e400071a805d6229223a98899e9da8c6233704a1 I added support for the
receiver that comes with the G602 device, but unfortunately I screwed up
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.

[ Upstream commit a0312af1f94d13800e63a7d0a66e563582e39aec ]
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;

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.

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.

[ Upstream commit 652f3d00de523a17b0cebe7b90debccf13aa8c31 ]
The Varmilo VA104M Keyboard (04b4:07b1, reported as Varmilo Z104M)
exposes media control hotkeys as a USB HID consumer control device, but
these keys do not work in the current (5.8-rc1) kernel due to the
incorrect HID report descriptor. Fix the problem by modifying the
internal HID report descriptor.
More specifically, the keyboard report descriptor specifies the
logical boundary as 572~10754 (0x023c ~ 0x2a02) while the usage
boundary is specified as 0~10754 (0x00 ~ 0x2a02). This results in an
incorrect interpretation of input reports, causing inputs to be ignored.
By setting the Logical Minimum to zero, we align the logical boundary
with the Usage ID boundary.
Some notes:
* There seem to be multiple variants of the VA104M keyboard. This
patch specifically targets 04b4:07b1 variant.
* The device works out-of-the-box on Windows platform with the generic
consumer control device driver (hidserv.inf). This suggests that
Windows either ignores the Logical Minimum/Logical Maximum or
interprets the Usage ID assignment differently from the linux
implementation; Maybe there are other devices out there that only
works on Windows due to this problem?

[ Upstream commit 3c785a06dee99501a17f8e8cf29b2b7e3f1e94ea ]
The usb-hid keyboard-dock for the Acer Switch 10 SW5-012 model declares
an application and hid-usage page of 0x0088 for the INPUT(4) report which
it sends. This reports contains 2 8-bit fields which are declared as
HID_MAIN_ITEM_VARIABLE.
The keyboard-touchpad combo never actually generates this report, except
when the touchpad is toggled on/off with the Fn + F7 hotkey combo. The
toggle on/off is handled inside the keyboard-dock, when the touchpad is
toggled off it simply stops sending events.
When the touchpad is toggled on/off an INPUT(4) report is generated with
the first content byte set to 120/121, before this commit the kernel
would report this as ABS_MISC 120/121 events.
Patch the descriptor to replace the HID_MAIN_ITEM_VARIABLE with
HID_MAIN_ITEM_RELATIVE (because no key-presss release events are send)
and add mappings for the 0x00880078 and 0x00880079 usages to generate
touchpad on/off key events when the touchpad is toggled on/off.

[ Upstream commit b4c00e7976636f33a4f67eab436a11666c8afd60 ]
Some users are pairing the Dinovo keyboards with the MX5000 or MX5500
receivers, instead of with the Dinovo receivers. The receivers are
mostly the same (and the air protocol obviously is compatible) but
currently the Dinovo receivers are handled by hid-lg.c while the
MX5x00 receivers are handled by logitech-dj.c.
When using a Dinovo keyboard, with its builtin touchpad, through
logitech-dj.c then the touchpad stops working because when asking the
receiver for paired devices, we get only 1 paired device with
a device_type of REPORT_TYPE_KEYBOARD. And since we don't see a paired
mouse, we have nowhere to send mouse-events to, so we drop them.
Extend the existing fix for the Dinovo Edge for this to also cover the
Dinovo Mini keyboard and also add a mapping to logitech-hidpp for the
Media key on the Dinovo Mini, so that that keeps working too.

[ Upstream commit ee5e58418a854755201eb4952b1230d873a457d5 ]
Some quad/bluetooth keyboards, such as the Dinovo Edge (Y-RAY81) have a
builtin touchpad. In this case when asking the receiver for paired devices,
we get only 1 paired device with a device_type of REPORT_TYPE_KEYBOARD.
This means that we do not instantiate a second dj_hiddev for the mouse
(as we normally would) and thus there is no place for us to forward the
mouse input reports to, causing the touchpad part of the keyboard to not
work.
There is no way for us to detect these keyboards, so this commit adds
an array with device-ids for such keyboards and when a keyboard is on
this list it adds STD_MOUSE to the reports_supported bitmap for the
dj_hiddev created for the keyboard fixing the touchpad not working.
Using a list of device-ids for this is not ideal, but there are only
very few such keyboards so this should be fine. Besides the Dinovo Edge,
other known wireless Logitech keyboards with a builtin touchpad are:
* Dinovo Mini (TODO add its device-id to the list)
* K400 (uses a unifying receiver so is not affected)
* K600 (uses a unifying receiver so is not affected)

commit d9216d753b2b1406b801243b12aaf00a5ce5b861 upstream.
It has recently been reported that the "heartbeat" report from devices
like the 2nd-gen Intuos Pro (PTH-460, PTH-660, PTH-860) or the 2nd-gen
Bluetooth-enabled Intuos tablets (CTL-4100WL, CTL-6100WL) can cause the
driver to send a spurious BTN_TOUCH=0 once per second in the middle of
drawing. This can result in broken lines while drawing on Chrome OS.
The source of the issue has been traced back to a change which modified
the driver to only call `wacom_wac_pad_report()` once per report instead
of once per collection. As part of this change, pad-handling code was
removed from `wacom_wac_collection()` under the assumption that the
`WACOM_PEN_FIELD` and `WACOM_TOUCH_FIELD` checks would not be satisfied
when a pad or battery collection was being processed.
To be clear, the macros `WACOM_PAD_FIELD` and `WACOM_PEN_FIELD` do not
currently check exclusive conditions. In fact, most "pad" fields will
also appear to be "pen" fields simply due to their presence inside of
a Digitizer application collection. Because of this, the removal of
the check from `wacom_wac_collection()` just causes pad / battery
collections to instead trigger a call to `wacom_wac_pen_report()`
instead. The pen report function in turn resets the tip switch state
just prior to exiting, resulting in the observed BTN_TOUCH=0 symptom.
To correct this, we restore a version of the `WACOM_PAD_FIELD` check
in `wacom_wac_collection()` and return early. This effectively prevents
pad / battery collections from being reported until the very end of the
report as originally intended.

[ Upstream commit 5bf2f2f331ad812c9b7eea6e14a3ea328acbffc0 ]
The Acer One S1003 2-in-1 keyboard dock uses a Synaptics S910xx touchpad
which is connected to an ITE 8910 USB keyboard controller chip.
This keyboard has the same quirk for its rfkill / airplane mode hotkey as
other keyboards with ITE keyboard chips, it only sends a single release
event when pressed and released, it never sends a press event.
This commit adds this keyboards USB id to the hid-ite id-table, fixing
the rfkill key not working on this keyboard. Note that like for the
Acer Aspire Switch 10 (SW5-012) the id-table entry matches on the
HID_GROUP_GENERIC generic group so that hid-ite only binds to the
keyboard interface and the mouse/touchpad interface is left untouched
so that hid-multitouch can bind to it.

This code doesn't check if "settings->startup_profile" is within bounds
and that could result in an out of bounds array access. What the code
does do is it checks if the settings can be written to the firmware, so
it's possible that the firmware has a bounds check? It's safer and
easier to verify when the bounds checking is done in the kernel.

The Saitek X52 family of joysticks has a pair of axes that were
originally (by the Windows driver) used as mouse pointer controls. The
corresponding usage page is the Game Controls page, which is not
recognized by the generic HID driver, and therefore, both axes get
mapped to ABS_MISC. The quirk makes the second axis get mapped to
ABS_MISC+1, and therefore made available separately.

commit 35556bed836f8dc07ac55f69c8d17dce3e7f0e25 upstream.
When calling into hid_map_usage(), the passed event code is
blindly stored as is, even if it doesn't fit in the associated bitmap.
This event code can come from a variety of sources, including devices
masquerading as input devices, only a bit more "programmable".
Instead of taking the event code at face value, check that it actually
fits the corresponding bitmap, and if it doesn't:
- spit out a warning so that we know which device is acting up
- NULLify the bitmap pointer so that we catch unexpected uses
Code paths that can make use of untrusted inputs can now check
that the mapping was indeed correct and bail out if not.

It appears that a ReportSize value of zero is legal, even if a bit
non-sensical. Most of the HID code seems to handle that gracefully,
except when computing the total size in bytes. When fed as input to
memset, this leads to some funky outcomes.

commit eef4016243e94c438f177ca8226876eb873b9c75 upstream.
Before this commit i2c_hid_parse() consists of the following steps:
1. Send power on cmd
2. usleep_range(1000, 5000)
3. Send reset cmd
4. Wait for reset to complete (device interrupt, or msleep(100))
5. Send power on cmd
6. Try to read HID descriptor
Notice how there is an usleep_range(1000, 5000) after the first power-on
command, but not after the second power-on command.
Testing has shown that at least on the BMAX Y13 laptop's i2c-hid touchpad,
not having a delay after the second power-on command causes the HID
descriptor to read as all zeros.
In case we hit this on other devices too, the descriptor being all zeros
can be recognized by the following message being logged many, many times:
hid-generic 0018:0911:5288.0002: unknown main item tag 0x0
At the same time as the BMAX Y13's touchpad issue was debugged,
Kai-Heng was working on debugging some issues with Goodix i2c-hid
touchpads. It turns out that these need a delay after a PWR_ON command
too, otherwise they stop working after a suspend/resume cycle.
According to Goodix a delay of minimal 60ms is needed.
Having multiple cases where we need a delay after sending the power-on
command, seems to indicate that we should always sleep after the power-on
command.
This commit fixes the mentioned issues by moving the existing 1ms sleep to
the i2c_hid_set_power() function and changing it to a 60ms sleep.

commit 4f57cace81438cc873a96f9f13f08298815c9b51 upstream.
Some devices, particularly the 3DConnexion Spacemouse wireless 3D
controllers, return more than just the battery capacity in the battery
report. The Spacemouse devices return an additional byte with a device
specific field. However, hidinput_query_battery_capacity() only
requests a 2 byte transfer.
When a spacemouse is connected via USB (direct wire, no wireless dongle)
and it returns a 3 byte report instead of the assumed 2 byte battery
report the larger transfer confuses and frightens the USB subsystem
which chooses to ignore the transfer. Then after 2 seconds assume the
device has stopped responding and reset it. This can be reproduced
easily by using a wired connection with a wireless spacemouse. The
Spacemouse will enter a loop of resetting every 2 seconds which can be
observed in dmesg.
This patch solves the problem by increasing the transfer request to 4
bytes instead of 2. The fix isn't particularly elegant, but it is simple
and safe to backport to stable kernels. A further patch will follow to
more elegantly handle battery reports that contain additional data.

[ Upstream commit a5d81646fa294eed57786a9310b06ca48902adf8 ]
The Maxxter KB-BT-001 Bluetooth keyboard, which looks somewhat like the
Apple Wireless Keyboard, is using the vendor and product IDs (05AC:0239)
of the Apple Wireless Keyboard (2009 ANSI version) <sigh>.
But its F1 - F10 keys are marked as sending F1 - F10, not the special
functions hid-apple.c maps them too; and since its descriptors do not
contain the HID_UP_CUSTOM | 0x0003 usage apple-hid looks for for the
Fn-key, apple_setup_input() never gets called, so F1 - F6 are mapped
to key-codes which have not been set in the keybit array causing them
to not send any events at all.
The lack of a usage code matching the Fn key in the clone is actually
useful as this allows solving this problem in a generic way.
This commits adds a fn_found flag and it adds a input_configured
callback which checks if this flag is set once all usages have been
mapped. If it is not set, then assume this is a clone and clear the
quirks bitmap so that the hid-apple code does not add any special
handling to this keyboard.
This fixes F1 - F6 not sending anything at all and F7 - F12 sending
the wrong codes on the Maxxter KB-BT-001 Bluetooth keyboard and on
similar clones.
