[ Upstream commit e53fc232a65f7488ab75d03a5b95f06aaada7262 ]

When a hid-steam device is removed it must clean up the client_hdev used for
intercepting hidraw access. This can lead to scheduling deferred work to
reattach the input device. Though the cleanup cancels the deferred work, this
was done before the client_hdev itself is cleaned up, so it gets rescheduled.
This patch fixes the ordering to make sure the deferred work is properly
canceled.

[ Upstream commit 07583a0010696a17fb0942e0b499a62785c5fc9f ]

The system can experience a random crash a few minutes after the driver is
removed. This issue occurs due to improper handling of memory freeing in
the ishtp_hid_remove() function.

The function currently frees the `driver_data` directly within the loop
that destroys the HID devices, which can lead to accessing freed memory.
Specifically, `hid_destroy_device()` uses `driver_data` when it calls
`hid_ishtp_set_feature()` to power off the sensor, so freeing
`driver_data` beforehand can result in accessing invalid memory.

This patch resolves the issue by storing the `driver_data` in a temporary
variable before calling `hid_destroy_device()`, and then freeing the
`driver_data` after the device is destroyed.

[ Upstream commit 823987841424289339fdb4ba90e6d2c3792836db ]

During the `rmmod` operation for the `intel_ishtp_hid` driver, a
use-after-free issue can occur in the hid_ishtp_cl_remove() function.
The function hid_ishtp_cl_deinit() is called before ishtp_hid_remove(),
which can lead to accessing freed memory or resources during the
removal process.

Call Trace:

 ...

Additionally, ishtp_hid_remove() is a HID level power off, which should
occur before the ISHTP level disconnect.

This patch resolves the issue by reordering the calls in
hid_ishtp_cl_remove(). The function ishtp_hid_remove() is now
called before hid_ishtp_cl_deinit().

corsair_void_process_receiver can be called from an interrupt context,
locking battery_mutex in it was causing a kernel panic.
Fix it by moving the critical section into its own work, sharing this
work with battery_add_work and battery_remove_work to remove the need
for any locking

This happens due to the malformed report items sent by the emulated device
which results in a report, that has no fields, being added to the report list.
Due to this appleir_input_configured() is never called, hidinput_connect()
fails which results in the HID_CLAIMED_INPUT flag is not being set. However,
it  does not make appleir_probe() fail and lets the event callback to be
called without the associated input device.

Thus, add a check for the HID_CLAIMED_INPUT flag and leave the event hook
early if the driver didn't claim any input_dev for some reason. Moreover,
some other hid drivers accessing input_dev in their event callbacks do have
similar checks, too.

Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

This happens due to the malformed report items sent by the emulated device
which results in a report, that has no fields, being added to the report list.
Due to this appleir_input_configured() is never called, hidinput_connect()
fails which results in the HID_CLAIMED_INPUT flag is not being set. However,
it  does not make appleir_probe() fail and lets the event callback to be
called without the associated input device.

Thus, add a check for the HID_CLAIMED_INPUT flag and leave the event hook
early if the driver didn't claim any input_dev for some reason. Moreover,
some other hid drivers accessing input_dev in their event callbacks do have
similar checks, too.

[ Upstream commit 79504249d7e27cad4a3eeb9afc6386e418728ce0 ]

Due to an interplay between locking in the input and hid transport subsystems,
attempting to register or deregister the relevant input devices during the
hidraw open/close events can lead to a lock ordering issue. Though this
shouldn't cause a deadlock, this commit moves the input device manipulation to
deferred work to sidestep the issue.

[ Upstream commit cc4f952427aaa44ecfd92542e10a65cce67bd6f4 ]

When a force feedback command is sent from userspace, work is scheduled to pass
this data to the controller without blocking userspace itself. However, in
theory, this work might not be properly canceled if the controller is removed
at the exact right time. This patch ensures the work is properly canceled when
the device is removed.

[ Upstream commit b051ffa2aeb2a60e092387b6fb2af1ad42f51a3c ]

Lockdep reported that, as steam_do_deck_input_event is called from
steam_raw_event inside of an IRQ context, it can lead to issues if that IRQ
occurs while the work to be cancelled is running. By using cancel_delayed_work,
this issue can be avoided. The exact ordering of the work and the event
processing is not super important, so this is safe.

[ Upstream commit 0b43d98ff29be3144e86294486b1373b5df74c0e ]

Syzbot[1] has detected a stack-out-of-bounds read of the ep_addr array from
hid-thrustmaster driver. This array is passed to usb_check_int_endpoints
function from usb.c core driver, which executes a for loop that iterates
over the elements of the passed array. Not finding a null element at the end of
the array, it tries to read the next, non-existent element, crashing the kernel.

To fix this, a 0 element was added at the end of the array to break the for
loop.
