commit e4940fe6322c851659c17852b671c6e7b1aa9f56 upstream.

Although it mimics the Microsoft's VendorID, it is in fact a clone.
Taking into account that the original Microsoft Receiver is not being
manufactured anymore, this drive can solve dpad issues encontered by
those who still use the original 360 Wireless controller
but are using a receiver clone.

e9ba82343e Input: atkbd - map F23 key to support default copilot shortcut
commit 907bc9268a5a9f823ffa751957a5c1dd59f83f42 upstream.

Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a
dedicated keycode, and multiple vendors have their keyboards emit this
sequence in response to users pressing a dedicated "Copilot" key.
Unfortunately the default keymap table in atkbd does not map scancode
0x6e (F23) and so the key combination does not work even if userspace
is ready to handle it.

Because this behavior is common between multiple vendors and the
scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that
key sequence is generated properly.

MS documentation for the scan code:
https://learn.microsoft.com/en-us/windows/win32/inputdev/about-keyboard-input#scan-codes
Confirmed on Lenovo, HP and Dell machines by Canonical.
Tested on Lenovo T14s G6 AMD.

a9beea8c85 Input: synaptics-rmi4 - fix UAF of IRQ domain on driver removal
commit fbf8d71742557abaf558d8efb96742d442720cc2 upstream.

Calling irq_domain_remove() will lead to freeing the IRQ domain
prematurely. The domain is still referenced and will be attempted to get
used via rmi_free_function_list() -> rmi_unregister_function() ->
irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer.

With PaX's MEMORY_SANITIZE this will lead to an access fault when
attempting to dereference embedded pointers, as in Torsten's report that
was faulting on the 'domain->ops->unmap' test.

Fix this by releasing the IRQ domain only after all related IRQs have
been deactivated.

597ff93029 Input: uinput - reject requests with unreasonable number of slots
[ Upstream commit 206f533a0a7c683982af473079c4111f4a0f9f5e ]

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

When exercising uinput interface syzkaller may try setting up device
with a really large number of slots, which causes memory allocation
failure in input_mt_init_slots(). While this allocation failure is
handled properly and request is rejected, it results in syzkaller
reports. Additionally, such request may put undue burden on the
system which will try to free a lot of memory for a bogus request.

Fix it by limiting allowed number of slots to 100. This can easily
be extended if we see devices that can track more than 100 contacts.

[ Upstream commit 38a38f5a36da9820680d413972cb733349400532 ]

When support for Silead touchscreens was orginal added some touchscreens
with older firmware versions only supported 5 fingers and this was made
the default requiring the setting of a "silead,max-fingers=10" uint32
device-property for all touchscreen models which do support 10 fingers.

There are very few models with the old 5 finger fw, so in practice the
setting of the "silead,max-fingers=10" is boilerplate which needs to
be copy and pasted to every touchscreen config.

Reporting that 10 fingers are supported on devices which only support
5 fingers doesn't cause any problems for userspace in practice, since
at max 4 finger gestures are supported anyways. Drop the max_fingers
configuration and simply always assume 10 fingers.

13528e1d8f Input: ff-core - prefer struct_size over open coded arithmetic
[ Upstream commit a08b8f8557ad88ffdff8905e5da972afe52e3307 ]

This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1][2].

As the "ff" variable is a pointer to "struct ff_device" and this
structure ends in a flexible array:

struct ff_device {
	[...]
	struct file *effect_owners[] __counted_by(max_effects);
};

the preferred way in the kernel is to use the struct_size() helper to
do the arithmetic instead of the calculation "size + count * size" in
the kzalloc() function.

The struct_size() helper returns SIZE_MAX on overflow. So, refactor
the comparison to take advantage of this.

This way, the code is more readable and safer.

This code was detected with the help of Coccinelle, and audited and
modified manually.

08637180f7 Input: try trimming too long modalias strings
commit 0774d19038c496f0c3602fb505c43e1b2d8eed85 upstream.

If an input device declares too many capability bits then modalias
string for such device may become too long and not fit into uevent
buffer, resulting in failure of sending said uevent. This, in turn,
may prevent userspace from recognizing existence of such devices.

This is typically not a concern for real hardware devices as they have
limited number of keys, but happen with synthetic devices such as
ones created by xen-kbdfront driver, which creates devices as being
capable of delivering all possible keys, since it doesn't know what
keys the backend may produce.

To deal with such devices input core will attempt to trim key data,
in the hope that the rest of modalias string will fit in the given
buffer. When trimming key data it will indicate that it is not
complete by placing "+," sign, resulting in conversions like this:

old: k71,72,73,74,78,7A,7B,7C,7D,8E,9E,A4,AD,E0,E1,E4,F8,174,
new: k71,72,73,74,78,7A,7B,7C,+,

This should allow existing udev rules continue to work with existing
devices, and will also allow writing more complex rules that would
recognize trimmed modalias and check input device characteristics by
other means (for example by parsing KEY= data in uevent or parsing
input device sysfs attributes).

Note that the driver core may try adding more uevent environment
variables once input core is done adding its own, so when forming
modalias we can not use the entire available buffer, so we reduce
it by somewhat an arbitrary amount (96 bytes).

The touchpad is connected both via i2c-hid and PS/2, the predecessor of
this device (NS70MU) has the same layout in this regard and also strange
behaviour caused by the psmouse and the i2c-hid driver fighting over
touchpad control. This fix is reusing the same workaround by just
disabling the PS/2 aux port, that is only used by the touchpad, to give the
i2c-hid driver the lone control over the touchpad.

The problem appears to be that atkbd_probe() fails when called
from atkbd_reconnect() on resume, which on systems where
ATKBD_CMD_GETID is skipped can only happen by ATKBD_CMD_SETLEDS
failing. ATKBD_CMD_SETLEDS failing because ATKBD_CMD_GETID was

After the laptop lid is opened, and the device resumes from S3 deep
sleep, if the user presses a keyboard key while the screen is still black,
the mouse and keyboard become unusable.

Enabling this quirk prevents this behavior from occurring.

2c70bf9978 Input: atkbd - skip ATKBD_CMD_GETID in translated mode
[ Upstream commit 936e4d49ecbc8c404790504386e1422b599dec39 ]

There have been multiple reports of keyboard issues on recent laptop models
which can be worked around by setting i8042.dumbkbd, with the downside
being this breaks the capslock LED.

It seems that these issues are caused by recent laptops getting confused by
ATKBD_CMD_GETID. Rather then adding and endless growing list of quirks for
this, just skip ATKBD_CMD_GETID alltogether on laptops in translated mode.

The main goal of sending ATKBD_CMD_GETID is to skip binding to ps/2
mice/touchpads and those are never used in translated mode.

Examples of laptop models which benefit from skipping ATKBD_CMD_GETID:

* "HP Laptop 15s-fq2xxx", "HP laptop 15s-fq4xxx" and "HP Laptop 15-dy2xxx"
  models the kbd stops working for the first 2 - 5 minutes after boot
  (waiting for EC watchdog reset?)

* On "HP Spectre x360 13-aw2xxx" atkbd fails to probe the keyboard

* At least 9 different Lenovo models have issues with ATKBD_CMD_GETID, see:
  https://github.com/yescallop/atkbd-nogetid

This has been tested on:

1. A MSI B550M PRO-VDH WIFI desktop, where the i8042 controller is not
   in translated mode when no keyboard is plugged in and with a ps/2 kbd
   a "AT Translated Set 2 keyboard" /dev/input/event# node shows up

2. A Lenovo ThinkPad X1 Yoga gen 8 (always has a translated set 2 keyboard)

[ Upstream commit 5030b2fe6aab37fe42d14f31842ea38be7c55c57 ]

Touch controllers need some time after receiving reset command for the
firmware to finish re-initializing and be ready to respond to commands
from the host. The driver already had handling for the post-reset delay
for I2C and SPI transports, this change adds the handling to
SMBus-connected devices.

SMBus devices are peculiar because they implement legacy PS/2
compatibility mode, so reset is actually issued by psmouse driver on the
associated serio port, after which the control is passed to the RMI4
driver with SMBus companion device.

Note that originally the delay was added to psmouse driver in
92e24e0e57f7 ("Input: psmouse - add delay when deactivating for SMBus
mode"), but that resulted in an unwanted delay in "fast" reconnect
handler for the serio port, so it was decided to revert the patch and
have the delay being handled in the RMI4 driver, similar to the other
transports.

[ Upstream commit 80f39e1c27ba9e5a1ea7e68e21c569c9d8e46062 ]

In the initial boot stage the integrated keyboard of Fujitsu Lifebook E5411
refuses to work and it's not possible to type for example a dm-crypt
passphrase without the help of an external keyboard.

i8042.nomux kernel parameter resolves this issue but using that a PS/2
mouse is detected. This input device is unused even when the i2c-hid-acpi
kernel module is blacklisted making the integrated ELAN touchpad
(04F3:308A) not working at all.

Since the integrated touchpad is managed by the i2c_designware input
driver in the Linux kernel and you can't find a PS/2 mouse port on the
computer I think it's safe to not use the PS/2 mouse port at all.

commit e2cb5cc822b6c9ee72c56ce1d81671b22c05406a upstream.

When the SMBus connection is attempted psmouse_smbus_init() sets
the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus
initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will
fallback to PS/2 mode, replacing the psmouse private data. This can cause
issues on resume, since psmouse_smbus_reconnect() expects to find an
instance of struct psmouse_smbus_dev in psmouse->private.

The issue was uncovered when in 92e24e0e57f7 ("Input: psmouse - add
delay when deactivating for SMBus mode") psmouse_smbus_reconnect()
started attempting to use more of the data structure. The commit was
since reverted, not because it was at fault, but because there was found
a better way of doing what it was attempting to do.

Fix the problem by resetting the fast_reconnect pointer in psmouse
structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2
mode is used.

syzbot has found a use-after-free bug [1] in the powermate driver. This
happens when the device is disconnected, which leads to a memory free from
the powermate_device struct.  When an asynchronous control message
completes after the kfree and its callback is invoked, the lock does not
exist anymore and hence the bug.

Use usb_kill_urb() on pm->config to cancel any in-progress requests upon
device disconnection.

[ Upstream commit eb09074bdb05ffd6bfe77f8b4a41b76ef78c997b ]

The touchpad of this device is both connected via PS/2 and i2c. This causes
strange behavior when both driver fight for control. The easy fix is to
prevent the PS/2 driver from accessing the mouse port as the full feature
set of the touchpad is only supported in the i2c interface anyway.

The strange behavior in this case is, that when an external screen is
connected and the notebook is closed, the pointer on the external screen is
moving to the lower right corner. When the notebook is opened again, this
movement stops, but the touchpad clicks are unresponsive afterwards until
reboot.

282a96e3f8 Input: xpad - delete a Razer DeathAdder mouse VID/PID entry
commit feee70f4568650cf44c573488798ffc0a2faeea3 upstream.

While doing my research to improve the xpad device names I noticed
that the 1532:0037 VID/PID seems to be used by the DeathAdder 2013,
so that Razer Sabertooth instance looked wrong and very suspect to
me. I didn't see any mention in the official drivers, either.

After doing more research, it turns out that the xpad list
is used by many other projects (like Steam) as-is [1], this
issue was reported [2] and Valve/Sam Lantinga fixed it [3]:

[1]: dcc5eef0e2/src/joystick/controller_type.h (L251)
[2]: https://steamcommunity.com/app/353380/discussions/0/1743392486228754770/
[3]: https://hg.libsdl.org/SDL/rev/29809f6f0271

(With multiple Internet users reporting similar issues, not linked here)

After not being able to find the correct VID/PID combination anywhere
on the Internet and not receiving any reply from Razer support I did
some additional detective work, it seems like it presents itself as
"Razer Sabertooth Gaming Controller (XBOX360)", code 1689:FE00.

Leaving us with this:
 * Razer Sabertooth (1689:fe00)
 * Razer Sabertooth Elite (24c6:5d04)
 * Razer DeathAdder 2013 (1532:0037) [note: not a gamepad]

So, to sum things up; remove this conflicting/duplicate entry:

{ 0x1532, 0x0037, "Razer Sabertooth", 0, XTYPE_XBOX360 },

As the real/correct one is already present there, even if
the Internet as a whole insists on presenting it as the
Razer Sabertooth Elite, which (by all accounts) is not:

{ 0x1689, 0xfe00, "Razer Sabertooth", 0, XTYPE_XBOX360 },

0638dcc7e7 treewide: Remove uninitialized_var() usage
commit 3f649ab728cda8038259d8f14492fe400fbab911 upstream.

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:

git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
	xargs perl -pi -e \
		's/\buninitialized_var\(([^\)]+)\)/\1/g;
		 s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'

drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.

No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

2e64d7b182 treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()
[ Upstream commit b13fecb1c3a603c4b8e99b306fecf4f668c11b32 ]

This converts all the existing DECLARE_TASKLET() (and ...DISABLED)
macros with DECLARE_TASKLET_OLD() in preparation for refactoring the
tasklet callback type. All existing DECLARE_TASKLET() users had a "0"
data argument, it has been removed here as well.

[Tom: fix backport to 5.4.y]

AUTOSEL backport to 5.4.y of:
b13fecb1c3a6 ("treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()")
changed all locations of DECLARE_TASKLET with DECLARE_TASKLET_OLD,
except one, in arch/mips/lasat/pcivue_proc.c.

This is due to:
10760dde9be3 ("MIPS: Remove support for LASAT") preceeding
b13fecb1c3a6 ("treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()")
upstream and the former not being present in 5.4.y.

Fix this by changing DECLARE_TASKLET to DECLARE_TASKLET_OLD in
arch/mips/lasat/pcivue_proc.c.

99c8ba920f Input: goodix - add Lenovo Yoga Book X90F to nine_bytes_report DMI table
commit 8a0432bab6ea3203d220785da7ab3c7677f70ecb upstream.

The Android Lenovo Yoga Book X90F / X90L uses the same goodix touchscreen
with 9 bytes touch reports for its touch keyboard as the already supported
Windows Lenovo Yoga Book X91F/L, add a DMI match for this to
the nine_bytes_report DMI table.

When the quirk for the X91F/L was initially added it was written to
also apply to the X90F/L but this does not work because the Android
version of the Yoga Book uses completely different DMI strings.
Also adjust the X91F/L quirk to reflect that it only applies to
the X91F/L models.

commit 8980f190947ba29f23110408e712444884b74251 upstream.

The recent change of -funsigned-char causes additions of negative
numbers to become additions of large positive numbers, leading to wrong
calculations of mouse movement. Change these casts to be explicitly
signed, to take into account negative offsets.

f0f85f5e40 Input: alps - fix compatibility with -funsigned-char
commit 754ff5060daf5a1cf4474eff9b4edeb6c17ef7ab upstream.

The AlpsPS/2 code previously relied on the assumption that `char` is a
signed type, which was true on x86 platforms (the only place where this
driver is used) before kernel 6.2. However, on 6.2 and later, this
assumption is broken due to the introduction of -funsigned-char as a new
global compiler flag.

Fix this by explicitly specifying the signedness of `char` when sign
extending the values received from the device.
