346338ef00 HID: apple: Swap the Fn and Left Control keys on Apple keyboards
This patch allows users to swap the Fn and left Control keys on all Apple
keyboards: internal (e.g. Macbooks) and external (both wired and wireless).
The patch adds a new hid-apple module param: swap_fn_leftctrl (off by default).

5fc70e350e Input: introduce input_mt_report_slot_inactive()
input_mt_report_slot_state() ignores "tool" argument when the slot is
closed, which has caused a bit of confusion. Let's introduce
input_mt_report_slot_inactive() to report inactive slot state.

Since commit 4bc43a4212 ("HID: asus: Add
hid_is_using_ll_driver(usb_hid_driver) check") the hid-asus.c depends
on the usb_hid_driver symbol. Add a depends on USB_HID to Kconfig to

350bd245fc HID: asus: Fix mute and touchpad-toggle keys on Medion Akoya E1239T
The mute key, is broken. All the consumer keys on the keyboard USB
interface work normally, except for mute which only sends press events
and never sends release events.

The touchpad key sends the otherwise unused input report with a report-id
of 5 on the touchpad interface. It too only sends press events. This also
requires extra special handling since the multi-touch touchpad events and
the KEY_F21 events for the touchpad toggle must not be send from the same
input_dev (userspace cannot handle this).

This commit adds special handlig for both, fixing these keys not working.

a61f9e428b HID: asus: Add report_size to struct asus_touchpad_info
Add the report_size to struct asus_touchpad_info instead of calculating it.

This is a preparation patch for adding support for the multi-touch touchpad
found on the Medion Akoya E1239T's keyboard-dock, which uses the same
custom multi-touch protocol as the Asus keyboard-docks (same chipset

The only difference in that the Akoya E1239T keyboard-dock's input-reports
have a 5 byte footer instead of a 1 byte footer, which requires the
report_size to be configurable per touchpad-model.

a80b2f3098 HID: asus: Simplify skipping of mappings for Asus T100CHI keyboard-dock
Before this commit the code was trying to keep the mapping for the
left mouse-button, do avoid the hidinput_has_been_populated() check
in hid-input.c from triggering and causing the touchpad input_dev ro
get cleaned up.

But the hidinput_has_been_populated() check happens after the
input_configured callback which sets up all the input bit for the
touchpad, so there is no need to preserve the left button mapping.

4e4c60f826 HID: asus: Only set EV_REP if we are adding a mapping
Make asus_input_mapping() only set EV_REP if we are adding a mapping.

The T100CHI bluetooth keyboard dock has a few input reports for which
we do not create any mappings (these input-reports are present in the
descriptors but never send).

The hid-asus code relies on the HID core not creating input devices for
input-reports without any mappings. But the present of the EV_REP but
counts as a mapping causing 6 /dev/input/event# nodes to be created for
the T100CHI bluetooth keyboard dock. This change brings the amount of
created /dev/input/event# nodes / input-devices down to 4.

0ed08faded HID: usbhid: Fix race between usbhid_close() and usbhid_stop()
The syzbot fuzzer discovered a bad race between in the usbhid driver
between usbhid_stop() and usbhid_close().  In particular,
usbhid_stop() does:

	usb_free_urb(usbhid->urbin);
	...
	usbhid->urbin = NULL; /* don't mess up next start */

and usbhid_close() does:

	usb_kill_urb(usbhid->urbin);

with no mutual exclusion.  If the two routines happen to run
concurrently so that usb_kill_urb() is called in between the
usb_free_urb() and the NULL assignment, it will access the
deallocated urb structure -- a use-after-free bug.

This patch adds a mutex to the usbhid private structure and uses it to
enforce mutual exclusion of the usbhid_start(), usbhid_stop(),
usbhid_open() and usbhid_close() callbacks.

328de1c519 HID: mcp2221: add GPIO functionality support
MCP2221 has 4 pins that can be used as GPIO or configured
for alternate functionality such as clock generation and
IRQ detection. This patch adds support for GPIO functionality.

To set direction of a pin or to toggle its state after it
has been configured as GPIO, driver sends command to mcp2221
and parses response received from mcp2221. Based on this
response either 0 or appropriate error code is returned to
GPIO framework.

To get the direction or current state of a pin, driver
sends command and read response from the device. Based on
the response received from device direction or value
is sent to the GPIO framework.

Command from driver to mcp2221 device are output report.
Response received from mcp2221 is input report.

Datasheet (page 45-48) contains details about how to decode
the response received from device:

b43f977dd2 Revert "HID: wacom: generic: read the number of expected touches on a per collection basis"
This reverts commit 15893fa401.

The referenced commit broke pen and touch input for a variety of devices
such as the Cintiq Pro 32. Affected devices may appear to work normally
for a short amount of time, but eventually loose track of actual touch
state and can leave touch arbitration enabled which prevents the pen
from working. The commit is not itself required for any currently-available
Bluetooth device, and so we revert it to correct the behavior of broken
devices.

This breakage occurs due to a mismatch between the order of collections
and the order of usages on some devices. This commit tries to read the
contact count before processing events, but will fail if the contact
count does not occur prior to the first logical finger collection. This
is the case for devices like the Cintiq Pro 32 which place the contact
count at the very end of the report.

Without the contact count set, touches will only be partially processed.
The `wacom_wac_finger_slot` function will not open any slots since the
number of contacts seen is greater than the expectation of 0, but we will
still end up calling `input_mt_sync_frame` for each finger anyway. This
can cause problems for userspace separate from the issue currently taking
place in the kernel. Only once all of the individual finger collections
have been processed do we finally get to the enclosing collection which
contains the contact count. The value ends up being used for the *next*
report, however.

This delayed use of the contact count can cause the driver to loose track
of the actual touch state and believe that there are contacts down when
there aren't. This leaves touch arbitration enabled and prevents the pen
from working. It can also cause userspace to incorrectly treat single-
finger input as gestures.

778fbf4179 HID: wacom: Read HID_DG_CONTACTMAX directly for non-generic devices
We've recently switched from extracting the value of HID_DG_CONTACTMAX
at a fixed offset (which may not be correct for all tablets) to
injecting the report into the driver for the generic codepath to handle.
Unfortunately, this change was made for *all* tablets, even those which
aren't generic. Because `wacom_wac_report` ignores reports from non-
generic devices, the contact count never gets initialized. Ultimately
this results in the touch device itself failing to probe, and thus the
loss of touch input.

This commit adds back the fixed-offset extraction for non-generic devices.

56d8623ced HID: intel-ish-hid: hbm.h: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

71559219ce HID: intel-ish-hid: ishtp-dev.h: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

77a36a3ab4 HID: Add driver fixing Glorious PC Gaming Race mouse report descriptor
The Glorious Model O mice (and also at least the Model O-, which is
driver-wise the same mouse) have a bug in the descriptor of HID
Report with ID 2. This report is used for Consumer Control buttons,
which can be mapped using the provided Windows only software.

Here is an excerpt from the original descriptor:

  INPUT(2)[INPUT]
    Field(0)
      Flags( Constant Variable Absolute )
    Field(1)
      Flags( Constant Variable Absolute )
    Field(2)
      Flags( Constant Variable Absolute )

The issue is the Constant flag specified on all 3 fields, which
causes the hid driver to ignore changes in these fields and
essentialy causes the buttons to not work at all. The submitted driver
patches the descriptor to end up with the following:

  INPUT(2)[INPUT]
    Field(0)
      Flags( Variable Relative )
    Field(1)
      Flags( Variable Relative )
    Field(2)
      Flags( Variable Relative )

The Constant bit is reset and the Relative bit has been set in
order to prevent repeat events when holding down the button.

Additionally, the device name is changed from the hardware-reported
"SINOWEALTH Wired Gaming Mouse" to "Glorious Model O" or "Glorious
Model D".

b8a75eadda HID: lg-g15: Do not fail the probe when we fail to disable F# emulation
By default the G1-G12 keys on the Logitech gaming keyboards send
F1 - F12 when in "generic HID" mode.

The first thing the hid-lg-g15 driver does is disable this behavior.

We have received a bugreport that this does not work when the keyboard
is connected through an Aten KVM switch. Using a gaming keyboard with
a KVM is a bit weird setup, but still we can try to fail a bit more
gracefully here.

On the G510 keyboards the same USB-interface which is used for the gaming
keys is also used for the media-keys. Before this commit we would call
hid_hw_stop() on failure to disable the F# emulation and then exit the
probe method with an error code.

This not only causes us to not handle the gaming-keys, but this also
breaks the media keys which is a regression compared to the situation
when these keyboards where handled by the generic hidinput driver.

This commit changes the error handling to clear the hiddev drvdata
(to disable our .raw_event handler) and then returning from the probe
method with success.

The net result of this is that, when connected through a KVM, things
work as well as they did before the hid-lg-g15 driver was introduced.

Note: With commit 8ec321e96e ("HID: Fix slab-out-of-bounds read in

"controlled" at probe if there is a report too long in the HID
report-descriptor. hid_report_raw_event() is an exported symbol, so
presumabely we cannot always rely on this being the case.

beae56192a HID: ite: Only bind to keyboard USB interface on Acer SW5-012 keyboard dock
Commit 8f18eca9eb ("HID: ite: Add USB id match for Acer SW5-012 keyboard
dock") added the USB id for the Acer SW5-012's keyboard dock to the
hid-ite driver to fix the rfkill driver not working.

Most keyboard docks with an ITE 8595 keyboard/touchpad controller have the
"Wireless Radio Control" bits which need the special hid-ite driver on the
second USB interface (the mouse interface) and their touchpad only supports
mouse emulation, so using generic hid-input handling for anything but
the "Wireless Radio Control" bits is fine. On these devices we simply bind
to all USB interfaces.

But unlike other ITE8595 using keyboard docks, the Acer Aspire Switch 10
(SW5-012)'s touchpad not only does mouse emulation it also supports
HID-multitouch and all the keys including the "Wireless Radio Control"
bits have been moved to the first USB interface (the keyboard intf).

So we need hid-ite to handle the first (keyboard) USB interface and have
it NOT bind to the second (mouse) USB interface so that that can be
handled by hid-multitouch.c and we get proper multi-touch support.

This commit changes the hid_device_id for the SW5-012 keyboard dock to
only match on hid devices from the HID_GROUP_GENERIC group, this way
hid-ite will not bind the the mouse/multi-touch interface which has
HID_GROUP_MULTITOUCH_WIN_8 as group.
This fixes the regression to mouse-emulation mode introduced by adding
the keyboard dock USB id.

4ab2bb3c31 HID: logitech-hidpp: BatteryVoltage: only read chargeStatus if extPower is active
In the HID++ 2.0 function getBatteryInfo() from the BatteryVoltage
(0x1001) feature, chargeStatus is only valid if extPower is active.

Previously we were ignoring extPower, which resulted in wrong values.

Example:
    With an unplugged mouse

    $ cat /sys/class/power_supply/hidpp_battery_0/status
    Charging

This patch fixes that, it also renames charge_sts to flags as
charge_sts can be confused with chargeStatus from the spec.

20eee6e5af HID: steam: Fix input device disappearing
The `connected` value for wired devices was not properly initialized,
it must be set to `true` upon creation, because wired devices do not
generate connection events.

When a raw client (the Steam Client) uses the device, the input device
is destroyed. Then, when the raw client finishes, it must be recreated.
But since the `connected` variable was false this never happended.

be281368f2 hid-logitech-hidpp: read battery voltage from newer devices
Newer Logitech mice report their battery voltage through feature 0x1001
instead of the battery levels through feature 0x1000.

When the device is brought up and we try to query the battery, figure
out if it supports the old or the new feature. If it supports the new
feature, record the feature index and read the battery voltage and
its charge status. The device will respond with three bytes: the first
two are its voltage, and the last one is a bitset, reporting if the
battery is charging, fast or slow, in critical level or discharging.

If everything went correctly, record the fact that we're capable
of querying battery voltage.

Note that the protocol only gives us the current voltage in mV.
We store that as-is, but when queried, we report it in uV as
expected by sysfs.

Like we do for other ways of interacting with the battery for other
devices, refresh the battery status and notify the power supply
subsystem of the changes in voltage and status.

Since there are no known devices which implement both the old and the
new battery feature, we make sure to try the newer feature first and
only fall back to the old one if that fails.

18a1b06e5b HID: hiddev: fix mess in hiddev_open()
The open method of hiddev handler fails to bring the device out of
autosuspend state as was promised in 0361a28d3f, as it actually has 2
blocks that try to start the transport (call hid_hw_open()) with both
being guarded by the "open" counter, so the 2nd block is never executed as
the first block increments the counter so it is never at 0 when we check
it for the second block.

Additionally hiddev_open() was leaving counter incremented on errors,
causing the device to never be reopened properly if there was ever an
error.

Let's fix all of this by factoring out code that creates client structure
and powers up the device into a separate function that is being called
from usbhid_open() with the "existancelock" being held.

This keyboard has the same quirk for its rfkill / airplane mode hotkey as

8ec321e96e HID: Fix slab-out-of-bounds read in hid_field_extract
The syzbot fuzzer found a slab-out-of-bounds bug in the HID report
handler.  The bug was caused by a report descriptor which included a
field with size 12 bits and count 4899, for a total size of 7349
bytes.

The usbhid driver uses at most a single-page 4-KB buffer for reports.
In the test there wasn't any problem about overflowing the buffer,
since only one byte was received from the device.  Rather, the bug
occurred when the HID core tried to extract the data from the report
fields, which caused it to try reading data beyond the end of the
allocated buffer.

This patch fixes the problem by rejecting any report whose total
length exceeds the HID_MAX_BUFFER_SIZE limit (minus one byte to allow
for a possible report index).  In theory a device could have a report
longer than that, but if there was such a thing we wouldn't handle it
correctly anyway.

When polling a connected /dev/hidrawX device, it is useful to get the
EPOLLOUT when writing is possible. Since writing is possible as soon as
the device is connected, always return it.

Right now EPOLLOUT is only returned when there are also input reports
are available. This works if devices start sending reports when
connected, but some HID devices might need an output report first before
sending any input reports. This change will allow using EPOLLOUT here as
well.

0da522107e compat_ioctl: remove most of fs/compat_ioctl.c
As part of the cleanup of some remaining y2038 issues, I came to
 fs/compat_ioctl.c, which still has a couple of commands that need support
 for time64_t.
 
 In completely unrelated work, I spent time on cleaning up parts of this
 file in the past, moving things out into drivers instead.
 
 After Al Viro reviewed an earlier version of this series and did a lot
 more of that cleanup, I decided to try to completely eliminate the rest
 of it and move it all into drivers.
 
 This series incorporates some of Al's work and many patches of my own,
 but in the end stops short of actually removing the last part, which is
 the scsi ioctl handlers. I have patches for those as well, but they need
 more testing or possibly a rewrite.

This behavior can be avoided by disabling the Hyper-V mouse device as

8725aa4fa7 HID: rmi: Check that the RMI_STARTED bit is set before unregistering the RMI transport device
In the event that the RMI device is unreachable, the calls to rmi_set_mode() or
rmi_set_page() will fail before registering the RMI transport device. When the
device is removed, rmi_remove() will call rmi_unregister_transport_device()
which will attempt to access the rmi_dev pointer which was not set.
This patch adds a check of the RMI_STARTED bit before calling
rmi_unregister_transport_device().  The RMI_STARTED bit is only set
after rmi_register_transport_device() completes successfully.

The kernel oops was reported in this message:

2dbc6f113a HID: Improve Windows Precision Touchpad detection.
Per Microsoft spec, usage 0xC5 (page 0xFF) returns a blob containing
data used to verify the touchpad as a Windows Precision Touchpad.

   0x85, REPORTID_PTPHQA,    //    REPORT_ID (PTPHQA)
    0x09, 0xC5,              //    USAGE (Vendor Usage 0xC5)
    0x15, 0x00,              //    LOGICAL_MINIMUM (0)
    0x26, 0xff, 0x00,        //    LOGICAL_MAXIMUM (0xff)
    0x75, 0x08,              //    REPORT_SIZE (8)
    0x96, 0x00, 0x01,        //    REPORT_COUNT (0x100 (256))
    0xb1, 0x02,              //    FEATURE (Data,Var,Abs)

However, some devices, namely Microsoft's Surface line of products
instead implement a "segmented device certification report" (usage 0xC6)
which returns the same report, but in smaller chunks.

    0x06, 0x00, 0xff,        //     USAGE_PAGE (Vendor Defined)
    0x85, REPORTID_PTPHQA,   //     REPORT_ID (PTPHQA)
    0x09, 0xC6,              //     USAGE (Vendor usage for segment #)
    0x25, 0x08,              //     LOGICAL_MAXIMUM (8)
    0x75, 0x08,              //     REPORT_SIZE (8)
    0x95, 0x01,              //     REPORT_COUNT (1)
    0xb1, 0x02,              //     FEATURE (Data,Var,Abs)
    0x09, 0xC7,              //     USAGE (Vendor Usage)
    0x26, 0xff, 0x00,        //     LOGICAL_MAXIMUM (0xff)
    0x95, 0x20,              //     REPORT_COUNT (32)
    0xb1, 0x02,              //     FEATURE (Data,Var,Abs)

By expanding Win8 touchpad detection to also look for the segmented
report, all Surface touchpads are now properly recognized by
hid-multitouch.

1cb0d2aee2 HID: core: check whether Usage Page item is after Usage ID items
Upstream commit 58e7515500 ("HID: core: move Usage Page concatenation
to Main item") adds support for Usage Page item after Usage ID items
(such as keyboards manufactured by Primax).

Usage Page concatenation in Main item works well for following report
descriptor patterns:

    USAGE_PAGE (Keyboard)                   05 07
    USAGE_MINIMUM (Keyboard LeftControl)    19 E0
    USAGE_MAXIMUM (Keyboard Right GUI)      29 E7
    LOGICAL_MINIMUM (0)                     15 00
    LOGICAL_MAXIMUM (1)                     25 01
    REPORT_SIZE (1)                         75 01
    REPORT_COUNT (8)                        95 08
    INPUT (Data,Var,Abs)                    81 02

-------------

    USAGE_MINIMUM (Keyboard LeftControl)    19 E0
    USAGE_MAXIMUM (Keyboard Right GUI)      29 E7
    LOGICAL_MINIMUM (0)                     15 00
    LOGICAL_MAXIMUM (1)                     25 01
    REPORT_SIZE (1)                         75 01
    REPORT_COUNT (8)                        95 08
    USAGE_PAGE (Keyboard)                   05 07
    INPUT (Data,Var,Abs)                    81 02

But it makes the parser act wrong for the following report
descriptor pattern(such as some Gamepads):

    USAGE_PAGE (Button)                     05 09
    USAGE (Button 1)                        09 01
    USAGE (Button 2)                        09 02
    USAGE (Button 4)                        09 04
    USAGE (Button 5)                        09 05
    USAGE (Button 7)                        09 07
    USAGE (Button 8)                        09 08
    USAGE (Button 14)                       09 0E
    USAGE (Button 15)                       09 0F
    USAGE (Button 13)                       09 0D
    USAGE_PAGE (Consumer Devices)           05 0C
    USAGE (Back)                            0a 24 02
    USAGE (HomePage)                        0a 23 02
    LOGICAL_MINIMUM (0)                     15 00
    LOGICAL_MAXIMUM (1)                     25 01
    REPORT_SIZE (1)                         75 01
    REPORT_COUNT (11)                       95 0B
    INPUT (Data,Var,Abs)                    81 02

With Usage Page concatenation in Main item, parser recognizes all the
11 Usages as consumer keys, it is not the HID device's real intention.

This patch checks whether Usage Page is really defined after Usage ID
items by comparing usage page using status.

Usage Page concatenation on currently defined Usage Page will always
do in local parsing when Usage ID items encountered.

When Main item is parsing, concatenation will do again with last
defined Usage Page if this page has not been used in the previous
usages concatenation.

ff479731c3 HID: wacom: generic: Treat serial number and related fields as unsigned
The HID descriptors for most Wacom devices oddly declare the serial
number and other related fields as signed integers. When these numbers
are ingested by the HID subsystem, they are automatically sign-extended
into 32-bit integers. We treat the fields as unsigned elsewhere in the
kernel and userspace, however, so this sign-extension causes problems.
In particular, the sign-extended tool ID sent to userspace as ABS_MISC
does not properly match unsigned IDs used by xf86-input-wacom and libwacom.

We introduce a function 'wacom_s32tou' that can undo the automatic sign
extension performed by 'hid_snto32'. We call this function when processing
the serial number and related fields to ensure that we are dealing with
and reporting the unsigned form. We opt to use this method rather than
adding a descriptor fixup in 'wacom_hid_usage_quirk' since it should be
more robust in the face of future devices.

43b7029f47 HID: i2c-hid: Send power-on command after reset
Before commit 67b18dfb8c ("HID: i2c-hid: Remove runtime power
management"), any i2c-hid touchscreens would typically be runtime-suspended
between the driver loading and Xorg or a Wayland compositor opening it,
causing it to be resumed again. This means that before this change,
we would call i2c_hid_set_power(OFF), i2c_hid_set_power(ON) before the
graphical session would start listening to the touchscreen.

It turns out that at least some SIS touchscreens, such as the one found
on the Asus T100HA, need a power-on command after reset, otherwise they
will not send any events.

1832f2d8ff compat_ioctl: move more drivers to compat_ptr_ioctl
The .ioctl and .compat_ioctl file operations have the same prototype so
they can both point to the same function, which works great almost all
the time when all the commands are compatible.

One exception is the s390 architecture, where a compat pointer is only
31 bit wide, and converting it into a 64-bit pointer requires calling
compat_ptr(). Most drivers here will never run in s390, but since we now
have a generic helper for it, it's easy enough to use it consistently.

I double-checked all these drivers to ensure that all ioctl arguments
are used as pointers or are ignored, but are not interpreted as integer
values.

905d754c53 HID: logitech-hidpp: rework device validation
G920 device only advertises REPORT_ID_HIDPP_LONG and
REPORT_ID_HIDPP_VERY_LONG in its HID report descriptor, so querying
for REPORT_ID_HIDPP_SHORT with optional=false will always fail and
prevent G920 to be recognized as a valid HID++ device.

To fix this and improve some other aspects, modify
hidpp_validate_device() as follows:

  - Inline the code of hidpp_validate_report() to simplify
    distingushing between non-present and invalid report descriptors

  - Drop the check for id >= HID_MAX_IDS || id < 0 since all of our
    IDs are static and known to satisfy that at compile time

  - Change the algorithms to check all possible report
    types (including very long report) and deem the device as a valid
    HID++ device if it supports at least one

  - Treat invalid report length as a hard stop for the validation
    algorithm, meaning that if any of the supported reports has
    invalid length we assume the worst and treat the device as a
    generic HID device.

  - Fold initialization of hidpp->very_long_report_length into
    hidpp_validate_device() since it already fetches very long report
    length and validates its value

abdd3d0b34 HID: logitech-hidpp: split g920_get_config()
Original version of g920_get_config() contained two kind of actions:

    1. Device specific communication to query/set some parameters
       which requires active communication channel with the device,
       or, put in other way, for the call to be sandwiched between
       hid_device_io_start() and hid_device_io_stop().

    2. Input subsystem specific FF controller initialization which, in
       order to access a valid 'struct hid_input' via
       'hid->inputs.next', requires claimed hidinput which means be
       executed after the call to hid_hw_start() with connect_mask
       containing HID_CONNECT_HIDINPUT.

Location of g920_get_config() can only fulfill requirements for #1 and
not #2, which might result in following backtrace:

To solve this issue:

   1. Split g920_get_config() such that all of the device specific
      communication remains a part of the function and input subsystem
      initialization bits go to hidpp_ff_init()

   2. Move call to hidpp_ff_init() from being a part of
      g920_get_config() to be the last step of .probe(), right after a
      call to hid_hw_start() with connect_mask containing
      HID_CONNECT_HIDINPUT.

67b18dfb8c HID: i2c-hid: Remove runtime power management
Runtime power management in i2c-hid brings lots of issues, such as:
- When transitioning from display manager to desktop session, i2c-hid
was closed and opened, so the device was set to SLEEP and ON in a short
period. Vendors confirmed that their devices can't handle fast ON/SLEEP
command because Windows doesn't have this behavior.

- When rebooting, i2c-hid was closed, and the driver core put the device
back to full power before shutdown. This behavior also triggers a quick
SLEEP and ON commands that some devices can't handle, renders an
unusable touchpad after reboot.

- Most importantly, my power meter reports little to none energy saving
when i2c-hid is runtime suspended.

So let's remove runtime power management since there is no actual
benefit.

d9d4b1e46d HID: Fix assumption that devices have inputs
The syzbot fuzzer found a slab-out-of-bounds write bug in the hid-gaff
driver.  The problem is caused by the driver's assumption that the
device must have an input report.  While this will be true for all
normal HID input devices, a suitably malicious device can violate the
assumption.

The same assumption is present in over a dozen other HID drivers.
This patch fixes them by checking that the list of hid_inputs for the
hid_device is nonempty before allowing it to be used.

ad4203f5a2 HID: lg-g15: Add support for the G510 keyboards' gaming keys
Add support for the gaming and LCD menu keys on the G510 keyboard.

Note this commit does not add support for the keyboard and LCD backlight
and the status LEDs, this is done in a follow up commit.

Note the G510 generates 4 different input reports on its second
(Consumer Keys) interface:

-input report 1 is standard bootclass keyboard input report, mirroring
 normal keyboard interface
-input report 2 is consumer page keys
-input report 3 is gkeys, etc.
-input report 4 is LED status, single byte, bits:
 bit 2: kbd and LCD backlight is *off* when set, toggled by the light key
 bit 3: headphone mute LED
 bit 4: mic mute LED

Input-report 1 we ignore since this is a duplicate report from the first
interface, report 2 is handled by the regular hid-input code. In this
commit we add handling for input report 3.

b3a81c777d HID: fix error message in hid_open_report()
On HID report descriptor parsing error the code displays bogus
pointer instead of error offset (subtracts start=NULL from end).
Make the message more useful by displaying correct error offset
and include total buffer size for reference.

This was carried over from ancient times - "Fixed" commit just
promoted the message from DEBUG to ERROR.

b543db46b4 HID: google: whiskers: signal tablet mode on connect
When we receive "keyboard position" event from Whiskers we can
conclude that the base is attached, even if we did not get EC event
for that. We may miss EC event because there are some units which
have a lot of leakage on the ADC pins that the EC uses to determine
whether or not a base is attached.

79085c7dd2 HID: google: whiskers: signal tablet mode switch on disconnect
Currently, the tablet mode switch that takes two signals as its input:
base attached switch from the EC and some GMR signal from whiskers when
it's folded over. This tablet mode switch is then sent to Chrome, which
changes the UI.

However, there are some units which have a lot of leakage on the ADC
pins that the EC uses to determine whether or not a base is attached.
This can result in the base being physically detached, but the EC
thinking that it's still attached. The user would then be stuck in
laptop mode and wouldn't be able to rotate their display.

To work around this let's send "tablet mode" signal when we remove HID
interface, which normally happens when we physically disconnect
whiskers.

38e57f0693 HID: google: whiskers: more robust tablet mode detection
The USB interface may get detected before the platform/EC one, so let's
note the state of the base (if we receive event) and use it to correctly
initialize the tablet mode switch state.

Also let's start the HID interface immediately when probing, this will
ensure that we correctly process "base folded" events that may be sent
as we initialize the base. Note that this requires us to add a remove()
function where we stop and close the hardware and switch the LED
registration away from devm interface as we need to make sure that we
destroy the LED instance before we stop the hardware.

0af10eed9b HID: core: fix dmesg flooding if report field larger than 32bit
Only warn once of oversize hid report value field

On HP spectre x360 convertible the message:
hid-sensor-hub 001F:8087:0AC2.0002: hid_field_extract() called with n (192) > 32! (kworker/1:2)
is continually printed many times per second, crowding out all else.
Protect dmesg by printing the warning only one time.

The size of the hid report field data structure should probably be increased.
The data structure is treated as a u32 in Linux, but an unlimited number
of bits in the USB hid spec, so there is some rearchitecture needed now that
devices are sending more than 32 bits.

The problem is caused by the fact that pcmidi_get_output_report() will

This patch adds the missing check and aborts the probe operation if
necessary.

840d9f131f mfd / platform: cros_ec: Reorganize platform and mfd includes
There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.

In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:

 - Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
 - Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
   driver from include/linux/mfd/cros_ec.h to a new file
   include/linux/platform_data/cros_ec_proto.h
 - Update all the drivers with the new includes, so
   - Drivers that only need to know about the protocol include
     - linux/platform_data/cros_ec_proto.h
     - linux/platform_data/cros_ec_commands.h
   - Drivers that need to know about the cros-ec mfd device also include
     - linux/mfd/cros_ec.h

8ccff2843f HID: logitech-dj: Fix crash when initial logi_dj_recv_query_paired_devices fails
Before this commit dj_probe would exit with an error if the initial
logi_dj_recv_query_paired_devices fails. The initial call may fail
when the receiver is connected through a kvm and the focus is away.

When the call fails this causes 2 problems:

1) dj_probe calls logi_dj_recv_query_paired_devices after calling
hid_device_io_start() so a HID report may have been received in between
and our delayedwork_callback may be running. It seems that the initial
logi_dj_recv_query_paired_devices failure happening with some KVMs triggers
this exact scenario, causing the work-queue to run on free-ed memory,
leading to:

2) Even if we were to fix 1. by making sure the work is stopped before
failing probe, failing probe is the wrong thing to do, we have
logi_dj_recv_queue_unknown_work to deal with the initial
logi_dj_recv_query_paired_devices failure.

Rather then error-ing out of the probe, causing the receiver to not work at
all we should rely on this, so that the attached devices will get properly
enumerated once the KVM focus is switched back.

69ecd44d68 HID: multitouch: add support for the Smart Tech panel
This panel is not very friendly to us:
it exposes multiple multitouch collections, some of them being of
logical application stylus.

Usually, a device has only one report per application, and that is
what I assumed in commit 8dfe14b3b4 ("HID: multitouch: ditch mt_report_id")

To avoid breaking all working device, add a new class and a new quirk
for that situation.

c23e2043d5 HID: multitouch: do not filter mice nodes
It was a good idea at the time to not create a mouse node for the
multitouch touchscreens, but:
- touchscreens following the Win 8 protocol should not have this
  disturbing mouse node anymore, or if they have, it should be
  used for something else (like a joystick attached to the screen)
- touchpads have it, and they should not use it unless there is a bug,
  but when the laptop has a trackstick, the data are reported through this
  mouse node.

So instead of whitelisting all of the devices that have a need for the
mouse node, just export it.
hid-input.c will append a suffix to it ('Mouse'), so users will eventually
see if something goes wrong.

Some Wacom devices have keys with predefined meanings. However, when
support was originally added for these devices, the codes for these
keys were not available yet. These keys were thus reported with
the numbered KEY_PROG* range.

Some missing key codes were added with commit 4eb220cb35 ("HID:
wacom: generic: add 3 tablet touch keys") and we are now able to
report the proper key codes. We continue to report the original
KEY_PROG codes so as not to break any unknown applications that
may depend on them.

Also, to support the touch key, track its state in the pad report.

c1ca58f698 HID: intel-ish-hid: ipc: set NO_D3 flag only when needed
Currently, the NO_D3 flag is set in ish_probe(), and cleared in
ish_remove(). So even if the system goes into S3, ISH is still
in D0i3 state. It makes more sense that put ISH into D3 as system
goes into S3 and put ISH into D0i3 as system goes into suspend-to-idle.
I remove the NO_D3 setting in ish_probe(), so that ISH can enter
D3 state when system enters S3. Only set N0_D3 flag when system
enters the suspend-to-idle or platform specified, and clear it
when system resume.

When the ISH enters D3, the FW will check the DMA bit status.
If the DMA bit is set, the FW will reset automatically. So the
DMA bit need be clear before putting ISH into D3 state.

a3384b8d9f HID: logitech-hidpp: remove support for the G700 over USB
The G700 suffers from the same issue than the G502:
when plugging it in, the driver tries to contact it but it fails.

This timeout is problematic as it introduce a delay in the boot,
and having only the mouse event node means that the hardware
macros keys can not be relayed to the userspace.

addf3382c4 Revert "HID: logitech-hidpp: add USB PID for a few more supported mice"
This partially reverts commit 27fc32fd94.

It turns out that the G502 has some issues with hid-logitech-hidpp:
when plugging it in, the driver tries to contact it but it fails.
So the driver bails out leaving only the mouse event node available.

This timeout is problematic as it introduce a delay in the boot,
and having only the mouse event node means that the hardware
macros keys can not be relayed to the userspace.

Filipe and I just gave a shot at the following devices:

G403 Wireless (0xC082)
G703 (0xC087)
G703 Hero (0xC090)
G903 (0xC086)
G903 Hero (0xC091)
G Pro (0xC088)

Reverting the devices we are not sure that works flawlessly.

e0f6974a54 HID: sony: Fix race condition between rumble and device remove.
Valve reported a kernel crash on Ubuntu 18.04 when disconnecting a DS4
gamepad while rumble is enabled. This issue is reproducible with a
frequency of 1 in 3 times in the game Borderlands 2 when using an
automatic weapon, which triggers many rumble operations.

We found the issue to be a race condition between sony_remove and the
final device destruction by the HID / input system. The problem was
that sony_remove didn't clean some of its work_item state in
"struct sony_sc". After sony_remove work, the corresponding evdev
node was around for sufficient time for applications to still queue
rumble work after "sony_remove".

On pre-4.19 kernels the race condition caused a kernel crash due to a
NULL-pointer dereference as "sc->output_report_dmabuf" got freed during
sony_remove. On newer kernels this crash doesn't happen due the buffer
now being allocated using devm_kzalloc. However we can still queue work,
while the driver is an undefined state.

This patch fixes the described problem, by guarding the work_item
"state_worker" with an initialized variable, which we are setting back
to 0 on cleanup.

1c703b53e5 HID: input: fix a4tech horizontal wheel custom usage
Some a4tech mice use the 'GenericDesktop.00b8' usage to inform whether
the previous wheel report was horizontal or vertical. Before
c01908a14b ("HID: input: add mapping for "Toggle Display" key") this
usage was being mapped to 'Relative.Misc'. After the patch it's simply
ignored (usage->type == 0 & usage->code == 0). Which ultimately makes
hid-a4tech ignore the WHEEL/HWHEEL selection event, as it has no
usage->type.

We shouldn't rely on a mapping for that usage as it's nonstandard and
doesn't really map to an input event. So we bypass the mapping and make
sure the custom event handling properly handles both reports.

7bc74853fd HID: quirks: Set the INCREMENT_USAGE_ON_DUPLICATE quirk on Saitek X52
The Saitek X52 joystick has a pair of axes that are originally
(by the Windows driver) used as mouse pointer controls. The corresponding
usage->hid values are 0x50024 and 0x50026. Thus they are handled
as unknown axes and both get mapped to ABS_MISC. The quirk makes
the second axis to be mapped to ABS_MISC1 and thus made available
separately.

c801aff1a5 hiddev: Return EPOLLOUT from hiddev_poll
Always return EPOLLOUT from hiddev_poll when a device is connected.
This is safe since hiddev_write always fails and improves compatibility
with tools like socat.

378b80370a hidraw: Return EPOLLOUT from hidraw_poll
Always return EPOLLOUT from hidraw_poll when a device is connected.
This is safe since writes are always possible (but will always block).

hidraw does not support non-blocking writes and instead always calls
blocking backend functions on write requests. Hence, so far, a call to
poll never returned EPOLLOUT, which confuses tools like socat.

6fb08f1a5f HID: logitech-dj: Really fix return value of logi_dj_recv_query_hidpp_devices
Commit dbcbabf7da ("HID: logitech-dj: fix return value of
logi_dj_recv_query_hidpp_devices") made logi_dj_recv_query_hidpp_devices
return the return value of hid_hw_raw_request instead of unconditionally
returning 0.

But hid_hw_raw_request returns the report-size on a successful request
(and a negative error-code on failure) where as the callers of
logi_dj_recv_query_hidpp_devices expect a 0 return on success.

This commit fixes things so that either the negative error gets returned
or 0 on success, fixing HID++ receivers such as the Logitech nano receivers
no longer working.
