[PATCH 00/11] HID: storing pointers in 'hid_device_id::driver_data'

[PATCH 00/11] HID: storing pointers in 'hid_device_id::driver_data'

[Pawel Zalewski (The Capable Hub)]

The <linux/mod_devicetable.h> has multiple structs that follow
the pattern of having either 'driver_data' or 'driver_info'
fields which are of the 'kernel_ulong_t' type. Then how to 
interpret that field is user defined, some users will treat
the value as an actual integer, others as a valid pointer to
dereference. 

One of instances of the above is the 'hid_device_id::driver_data'
field, for the most part it is used for setting HID quirks and
treated as an integer value for storing metadata in the subsystem
drivers. But in a few instances it is used as a valid pointer to
dereference, namely in:
- hid-tmff
- wacom
 
One of the ways to fixing this duality and improve code readability
and type-safety a bit is to use a '{kernel_ulong_t, const void *}'
union. That way the current drivers that treat 'hid_device_id::driver_data'
as an integer value for storing metadata are unaffected. The drivers
that actually store pointers in there benefit from a removed cast
(and more clear intent) at the cost of using the new 'const void *'
field instead.

With the union in place, some of the existing initializers for static
const data now need a named field for the 'driver_data' - this is
also addressed in the series as part of the pre-clean up in 
patches 1-4. 

It was found that some modules use a bit of a type-unsafe way of storing
integers in the 'void *driver_data' pointer of the 'struct hid_device'
- this required a cast during storage via 'hid_set_drvdata' and a cast
during retrieval when using 'hid_get_drvdata'. I can see why this was 
done - as we potentially save on an allocation - but really code is
more readable and better quality without resorting to this. This issue
is also addressed in this patch series in patches 5-8 as part of the
pre-clean up.

The actual implementation and post-clean up can be found in 
patches 9-11.

The change also makes the code more portable on architecture 
like CHERI [1], where a pointer is replaced with a new primitive
(called the capability) at the architecture level and is as twice as
wide as the greatest representable address, ie. for 64 bit address
space capabilities are 128 bits wide (the other 64 bits are used to
store meta-data relating to the 64 bit address). So you can not store 
valid pointers inside 'unsigned long' as effectively a different set of
instructions is being generated by the compiler based on the data-type
that was used in C (ie. capabilities have their own set of load/store
that also copy over the meta-data which are orthogonal to the load/store
instructions used for plain integers that would invalidate the meta-data).
There is slightly more detail to this, but the above is enough to
explain the motivation - the proposed changes make the code a bit
better even without considering CHERI at all - as it is more readable 
and type-safe.

The series was built and tested under QEMU (boots with relevant 
configs set to Y) on arm64.

This series is part of a larger effort led by Uwe [2]

[PATCH 01/11] HID: hid-input: use named initializer for 'hid_battery_quirks[]'

[Pawel Zalewski (The Capable Hub)]

This makes the code a little bit more readable and consistent
with other drivers in the HID subsystem that assign the
'driver_data' field in the 'hid_device_id' struct explicitly.

While touching the 'hid_battery_quirks[]', align the list
terminator entry to use a space between the curly braces for
better matching the layout of the other entries.

It was confirmed that hid-input.o pre/post the patch are equal
using diffscope.

[PATCH 03/11] HID: hid-asus: use named initializer for 'asus_devices[]'

[Pawel Zalewski (The Capable Hub)]

This makes the code a little bit more readable and consistent
with other drivers in the HID subsystem that assign the
'driver_data' field in the 'hid_device_id' struct explicitly.

It was confirmed that hid-asus.o pre/post the patch are equal
using diffscope.

[PATCH 04/11] HID: i2c-hid-dmi-quirks: use named initializer for 'i2c_hid_elan_flipped_quirks[]'

[Pawel Zalewski (The Capable Hub)]

This makes the code a little bit more readable and consistent
with other drivers in the HID subsystem that assign the
'driver_data' field in the 'hid_device_id' struct explicitly.

It was confirmed that i2c-hid-dmi-quirks.o pre/post patch are equal
using diffscope.

[PATCH 06/11] HID: hid-cypress: clean up usage of 'driver_data'

[Pawel Zalewski (The Capable Hub)]

The module is storing an integer inside the drvdata pointer, which is
confusing - furthermore this integer is mutable. When its value is
changed it is set again using the 'hid_set_drvdata' API within
the 'cp_event' function.

Let's fix this, create and allocate the 'cp_device' struct that is then
set as the drvdata and then simply use its integer 'quirks' field for
storing the quirks, which shall make the code cleaner, type-safe,
consistent and more readable.

This makes the cast to (void *) during storage unnecessary and the cast
to (unsigned long) during retrieval is also removed.

[PATCH 09/11] HID: mod_devicetable: 'hid_device_id::driver_data' add union

[Pawel Zalewski (The Capable Hub)]

The 'driver_data' field can either be interpreted as an unsigned
numerical number or as a pointer - this depends on the driver within
HID subsystem. Unionise this unsigned value with a 'const void*'
pointer. This change allows to remove explicit casts to pointers
in the pointer-users case and as far as integer-users of the field
are concerned nothing has really changed.

The change doesn't affect the size and layout of struct hid_device_id
which is part of the userspace ABI.

This change aims to improve type-safety, readability - as the
intent is more clear - and portability of the code in the long term.

Remove the cast to (void *) during probe - tmff_init() second parameter
already accepts a const pointer, so no further action was needed here.

HID: wacom: use 'hid_device_id::driver_data_ptr'

This commit updates the wacom driver to use the driver_data_ptr field of
struct hid_device_id instead of casting the driver_data field. It improves
code readability by avoiding explicit casts to kernel_ulong_t and
struct wacom_features *.

This isn't a bug, but there's a typo (drvier_data_ptr) in the commit message.

Does this introduce a mixed declaration and code warning? The variable
declaration is placed in the middle of a block after executable statements.

Similarly, does this placement of id_features violate the coding style by
mixing declarations and code?

Additionally, earlier in wacom_probe() there is this check:

	if (!id->driver_data)
		return -EINVAL;

Since the goal is to transition to driver_data_ptr, should that check also be
updated to use id->driver_data_ptr for consistency?

If a new device ID is dynamically added to the HID driver via the sysfs
new_id interface without explicitly providing driver_data, does
id->driver_data_ptr default to NULL?

If id->driver_data_ptr is NULL, and the dynamically bound device contains
a THRUSTMASTER_USAGE_FF usage in its HID report descriptor, can this lead
to a NULL pointer dereference in tmff_init()?

Looking at tmff_init(), it appears to unconditionally dereference the
ff_bits pointer in this situation:

    for (i = 0; ff_bits[i] >= 0; i++)

Could this regression allow a standard administrative sysfs action to crash
the system? While the missing NULL check might predate these changes,
modifying the pointer extraction here seems like a good time to address it.

HID: mod_devicetable: 'hid_device_id::driver_data' add union

This commit adds a union to the driver_data field in struct hid_device_id
to provide a direct pointer representation.

> The change doesn't affect the size and layout of struct hid_device_id
> which is part of the userspace ABI.

Is this description accurate regarding the userspace ABI?

The structure struct hid_device_id is defined in
include/linux/mod_devicetable.h, which is an internal kernel header and is
not exported to include/uapi/.

While modpost uses the binary layout during the kernel build to generate
the text-based modules.alias file, userspace tools interact with the
generated text interface rather than the binary structure itself.

Could the commit message be updated to clarify that this layout is an
internal build ABI rather than a userspace ABI?

Does this code introduce a regression by encouraging an architectural
pattern where drivers assume they can dereference driver_data as a pointer?

The HID core supports dynamic device ID injection via the sysfs new_id
interface. In drivers/hid/hid-core.c, new_id_store() parses user input as
an unsigned long and assigns it to driver_data.

By adding driver_data_ptr, it explicitly blesses treating this field as a
kernel pointer at the core API level.

If a driver dereferences this user-provided value as a pointer during
probe, could it lead to arbitrary memory dereferences or lockdown bypasses?

Does it make more sense to keep driver_data restricted to an index or enum
to avoid exposing an API that facilitates this pattern?
