commit 18a1b06e5b91d47dc86c0a66a762646ea7c5d141 upstream.
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.

commit 9f3b61dc1dd7b81e99e7ed23776bb64a35f39e1a upstream.
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.

commit 8ec321e96e056de84022c032ffea253431a83c3c upstream.
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.

commit 1cb0d2aee26335d0bccf29100c7bed00ebece851 upstream.
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.

"Two fixes for the HID subsystem:

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid:
HID: wacom: generic: Treat serial number and related fields as unsigned
HID: i2c-hid: Send power-on command after reset
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.

Before commit 67b18dfb8c ("HID: i2c-hid: Remove runtime power

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.

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

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.

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

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.

Only warn once of oversize hid report value field
On HP spectre x360 convertible the message:

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.

hidp_send_message was changed to return non-zero values on success,
which some other bits did not expect. This caused spurious errors to be
propagated through the stack, breaking some drivers, such as hid-sony
for the Dualshock 4 in Bluetooth mode.

assumption as well.

This fixes an issue in which key down events for function keys would be
repeatedly emitted even after the user has raised the physical key. For
example, the driver fails to emit the F5 key up event when going through
the following steps:
- fnmode=1: hold FN, hold F5, release FN, release F5
- fnmode=2: hold F5, hold FN, release F5, release FN
The repeated F5 key down events can be easily verified using xev.

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

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.

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.

When calling request_threaded_irq() with a CP2112, the function
cp2112_gpio_irq_startup() is called in a IRQ context.
Therefore we can not sleep, and we can not call
cp2112_gpio_direction_input() there.
Move the call to cp2112_gpio_direction_input() earlier to have a working
driver.

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.

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.

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.

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.

This patch continues 10dce8af34 (fs: stream_open - opener for
stream-like files so that read and write can run simultaneously without
deadlock) and c5bf68fe0c (*: convert stream-like files from
nonseekable_open -> stream_open) and teaches steam_open.cocci to
consider files as being stream-like not only if they have
.llseek=no_llseek, but also if they have .llseek=noop_llseek.
This is safe to do: the comment about noop_llseek says
This is an implementation of ->llseek useable for the rare special case when
userspace expects the seek to succeed but the (device) file is actually not
able to perform the seek. In this case you use noop_llseek() instead of
falling back to the default implementation of ->llseek.
and in general noop_llseek was massively added to drivers in 6038f373a3
(llseek: automatically add .llseek fop) when changing default for NULL .llseek
from NOP to no_llseek with the idea to avoid breaking compatibility, if
maybe some user-space program was using lseek on a device without caring
about the result, but caring if it was an error or not.
Amended semantic patch produces two changes when applied tree-wide:
drivers/hid/hid-sensor-custom.c:690:8-24: WARNING: hid_sensor_custom_fops: .read() has stream semantic; safe to change nonseekable_open -> stream_open.
drivers/input/mousedev.c:564:1-17: ERROR: mousedev_fops: .read() can deadlock .write(); change nonseekable_open -> stream_open to fix.

Pull GPIO updates from Linus Walleij:
"This is the big slew of GPIO changes for the v5.3 kernel cycle. This
is mostly incremental work this time.
Three important things:
- The FMC subsystem is deleted through my tree. This happens through
GPIO as its demise was discussed in relation to a patch decoupling
its GPIO implementation from the standard way of handling GPIO. As
it turns out, that is not the only subsystem it reimplements and
the authors think it is better do scratch it and start over using
the proper kernel subsystems than try to polish the rust shiny. See
the commit (ACKed by the maintainers) for details.
- Arnd made a small devres patch that was ACKed by Greg and goes into
the device core.
- SPDX header change colissions may happen, because at times I've
seen that quite a lot changed during the -rc:s in regards to SPDX.
(It is good stuff, tglx has me convinced, and it is worth the
occasional pain.)
Apart from this is is nothing controversial or problematic.

There needs to be coordination between hid-quirks and the elan_i2c driver
about which devices are handled by what drivers. Currently, both use
whitelists, which results in valid devices being unhandled by default,
when they should not be rejected by hid-quirks. This is quickly becoming
an issue.
Since elan_i2c has a maintained whitelist of what devices it will handle,
which is now in a header file that hid-quirks can access, use that to
implement a blacklist in hid-quirks so that only the devices that need to
be handled by elan_i2c get rejected by hid-quirks, and everything else is
handled by default.

framebuffer_alloc() can fail only on kzalloc() memory allocation
failure and since kzalloc() will print error message in such case
we can omit printing extra error message in drivers (which BTW is
what the majority of framebuffer_alloc() users is doing already).

Currently, in suspend() and resume(), ishtp client drivers are using
driver_data to get "struct ishtp_cl_device" object which is set by
bus driver. It's wrong since the driver_data should not be owned bus.
driver_data should be owned by the corresponding ishtp client driver.
Due to this, some ishtp client driver like cros_ec_ishtp which uses
its driver_data to transfer its data to its child doesn't work correctly.
So this patch removes setting driver_data in bus drier and instead of
using driver_data to get "struct ishtp_cl_device", since "struct device"
is embedded in "struct ishtp_cl_device", we introduce a helper function
that returns "struct ishtp_cl_device" from "struct device".

The HID++ spec also defines very long HID++ reports, with a reportid of

Userspace (libmx5000) supports this, in order for this to work when talking

we need to properly forward these reports to the device.

The DSTS method detection mistakenly selects DCTS instead of DSTS if
nothing is returned when the method ID is not defined in WMNB. As a result,
the control of keyboard backlight is not functional for TUF Gaming series
laptops. Implement detection based on _UID of the WMI device instead.
There is evidence that DCTS is handled by ACPI WMI devices that have _UID
ASUSWMI, whereas none of the devices without ASUSWMI respond to DCTS and
DSTS is used instead [1].

Finger data is separated into chunks in our Bluetooth report,
where each report contains the same number of chunks. Those chunks
are not aligned in any particular way to a set of finger touches.
That is, the first half of a group of simultaneous touches may
be in one chunk at the end of a report and the second half could
be at the beginning of the next report.
Also some chunks contain no data and potentially some chunks could
contain leftover (bad) data.

In the generic code path, HID_DG_CONTACTMAX was previously
only read from the second byte of report 0x23.
Another report (0x82) has the HID_DG_CONTACTMAX in the
higher nibble of the third byte. We should support reading the
value of HID_DG_CONTACTMAX no matter what report we are reading
or which position that value is in.
To do this we submit the feature report as a event report
using hid_report_raw_event(). Our modified finger event path
records the value of HID_DG_CONTACTMAX when it sees that usage.

When a gpio_chip wants to request a descriptor from itself
using gpiochip_request_own_desc() it needs to be able to specify
fully how to use the descriptor, notably line inversion
semantics. The workaround in the gpiolib.c can be removed
and cases (such as SPI CS) where we need at times to request
a GPIO with line inversion semantics directly on a chip for
workarounds, can be fully supported with this call.
Fix up some users of the API that weren't really using the
last flag to set up the line as input or output properly
but instead just calling direction setting explicitly
after requesting the line.

The c52f nano receiver is a mouse only receiver. This means that it needs
some special handling compared to the c534 nano receiver:
1) It sends unnumbered mouse reports with a size of 8 bytes, so we need
to extend the unnumbered mouse report handling to support reports upto
8 bytes large
2) It mouse reports have the same high-resolution format as those from the
gaming mouse receivers
3) It can report consumer/multimedia buttons on its second interface, since
this is a mouse-only receiver these must be forwarded to the mouse child
device and not to the keyboard child-device (which will not exist)
