s32ton() shifts by n-1 where n is the field's report_size, a value that
comes directly from a HID device. The HID parser bounds report_size
only to <= 256, so a broken HID device can supply a report descriptor
with a wide field that triggers shift exponents up to 256 on a 32-bit
type when an output report is built via hid_output_field() or
hid_set_field().
Commit ec61b41918587 ("HID: core: fix shift-out-of-bounds in
hid_report_raw_event") added the same n > 32 clamp to the function
snto32(), but s32ton() was never given the same fix as I guess syzbot
hadn't figured out how to fuzz a device the same way.
Fix this up by just clamping the max value of n, just like snto32()
does.

commit b6a57912854e ("HID: logitech-dj: Prevent REPORT_ID_DJ_SHORT
related user initiated OOB write") assumed that all HID devices attached
to the logitech-dj driver was having an output report of DJ_SHORT.
However, on the receiver itself, we have 2 other HID device we attach
here: the mouse emulation and the keyboard emulation. For those devices
the value of rep is NULL and we are triggered a segfault here.
This is doubly required because logitech-dj also handles non DJ devices
that might not have the DJ collection.

The driver uses hidpp->send_receive_buf to point to a stack-allocated
buffer in the synchronous command path (__do_hidpp_send_message_sync).
However, this pointer is not cleared when the function returns.
If an event is processed (e.g. by a different thread) while the
send_mutex is held by a new command, but before that command has
updated send_receive_buf, the handler (hidpp_raw_hidpp_event) will
observe that the mutex is locked and dereference the stale pointer.
This results in an out-of-bounds access on a different thread's kernel
stack (or a NULL pointer dereference on the very first command).
Fix this by:
1. Clearing hidpp->send_receive_buf to NULL before releasing the mutex
in the synchronous command path.
2. Moving the assignment of the local 'question' and 'answer' pointers
inside the mutex_is_locked() block in the handler, and adding
a NULL check before dereferencing.

Commit d7db259bd6df ("HID: core: factor out hid_parse_collections()")
reworked collection parsing code and inadvertently allowed returning
"success" when parsing 0-sized reports where old code returned -EINVAL.
Restore the original behavior by doing an explicit check.
Note that the error message now differs from the generic "item fetching
failed at offset %u/%u" that is now used only for non-empty descriptors.

The DualShock 4 HID driver fails to validate the num_touch_reports field
received from the device in both USB and Bluetooth input reports.
A malicious device could set this field to a value larger than the
allocated size of the touch_reports array (3 for USB, 4 for Bluetooth),
leading to an out-of-bounds read in dualshock4_parse_report().
This can result in kernel memory disclosure when processing malicious
HID reports.
Validate num_touch_reports against the array size for the respective
connection types before processing the touch data.

You can build a USB device that includes a HID component
and a storage or UAS component. The components can be reset
only together. That means that hid_pre_reset() and hid_post_reset()
are in the block IO error handling. Hence no memory allocation
used in them may do block IO because the IO can deadlock
on the mutex held while resetting a device and calling the
interface drivers.
Use GFP_NOIO for all allocations in them.

The Logitech Bolt receiver once connected to a wireless device will
generate data on interface 2. If this data isn't polled, when the USB
port it is connected to gets suspended (and if that happens within 5
minutes of the last input from the wireless device), it will trigger a
remote wakeup 3 seconds later, which will result in a spurious system
wakeup if the port was suspended as part of system sleep.
Set the ALWAYS_POLL quirk for this device to ensure interface 2 is
always polled and this spurious wakeup never happens.
With this change in place the system can be suspended with the receiver
plugged in and the system can be woken up when an input is sent from the
wireless device.

logi_dj_recv_send_report() assumes that all incoming REPORT_ID_DJ_SHORT
reports are 14 Bytes (DJREPORT_SHORT_LENGTH - 1) long. It uses that
assumption to load the associated field's 'value' array with 14 Bytes of
data. However, if a malicious user only sends say 1 Byte of data,
'report_count' will be 1 and only 1 Byte of memory will be allocated to
the 'value' Byte array. When we come to populate 'value[1-13]' we will
experience an OOB write.

Currently the kernel is scheduled to do this call by itself, but it
requires a kernel v6.18 at least to have the INPUT_PROP set. For older
kernels, we can try to query the property from a HID-BPF probe, and set
a udev property based on that. This way we can provide the information
to old kernels without modifying them.

We want udev-hid-bpf to be able to set udev properties by printing them
out after the BPF object has been loaded. This allows to make a query to
the device, and set a udev prop based on the answer.
Because the way udev works, the properties are cleared on bind/unbind,
and we need a way to store them. After several attempts to keep the
property alive without re-running the udev-hid-bpf tool to communicate
with the device, it came out that HID-BPF maps are pinned in the bpffs
and we can then query them.
So the following would export a UDEV property in the bpffs:
EXPORT_UDEV_PROP(HID_FOO, 32);
SEC("syscall")
int probe(struct hid_bpf_probe_args *ctx)
{
const char *foo = "foo";
UDEV_PROP_SPRINTF(HID_FOO, "%s", foo);
return 0;
}
Then, we can debug it with a simple cat:
sudo cat /sys/fs/bpf/hid/.../UDEV_PROP_HID_FOO
0: {['f','o','o',],}
This way, the property is always accessible without talking to the
device

The subsequent dev_err() in sfh_init_work() for the same -EOPNOTSUPP

SPI port.
Supported frequencies include 50MHz (125MHz/2.5), 35MHz (125MHz/3.5),
and 10MHz (125MHz/8/1.5).

Enhance power management with two key improvements:
1. Hibernate support: Send POWER_OFF command when entering hibernate
mode.
2. Conditional sleep commands: Only send POWER_SLEEP/POWER_ON commands
during system suspend/resume when the touch device is not configured
as a wake source, preserving Wake-on-Touch (WoT) functionality. This
ensures proper power states while maintaining expected wake behavior.

In preparation to making use of __free(...) cleanup facilities to
clean up temporary buffers, factor out code parsing collections into
a separate function to make the code simpler.

The newly added hid-lenovo-go and hid-lenovo-go-s drivers attempt to
'select LEDS_CLASS', which has a dependency on NEW_LEDS, causing a build
failure when NEW_LEDS itself it disabled:
WARNING: unmet direct dependencies detected for LEDS_CLASS

Device drivers generally should not select other subsystems like this, as
that tends to cause dependency problems including loops in the dependency
graph.
Change these two and the older hid-lenovo driver to behave the same way as all
other HID drivers and use 'depends on LEDS_CLASS' or 'depends on LEDS_CLASS_MULTICOLOR'
instead, which itself has NEW_LEDS and LEDS_CLASS as dependencies.
