HID: check for valid USB device for many HID drivers

2021-12-14T09:04:47Z

commit 93020953d0fa7035fd036ad87a47ae2b7aa4ae33 upstream. Many HID drivers assume that the HID device assigned to them is a USB device as that was the only way HID devices used to be able to be created in Linux. However, with the additional ways that HID devices can be created for many different bus types, that is no longer true, so properly check that we have a USB device associated with the HID device before allowing a driver that makes this assumption to claim it.

HID: wacom: fix problems when device is not a valid USB device

2021-12-14T09:04:47Z

commit 720ac467204a70308bd687927ed475afb904e11b upstream. The wacom driver accepts devices of more than just USB types, but some code paths can cause problems if the device being controlled is not a USB device due to a lack of checking. Add the needed checks to ensure that the USB device accesses are only happening on a "real" USB device, and not one on some other bus.

HID: add USB_HID dependancy on some USB HID drivers

2021-12-14T09:04:47Z

commit f237d9028f844a86955fc9da59d7ac4a5c55d7d5 upstream. Some HID drivers are only for USB drivers, yet did not depend on CONFIG_USB_HID. This was hidden by the fact that the USB functions were stubbed out in the past, but now that drivers are checking for USB devices properly, build errors can occur with some random configurations.

HID: introduce hid_is_using_ll_driver

2021-12-14T09:04:46Z

commit fc2237a724a9e448599076d7d23497f51e2f7441 upstream. Although HID itself is transport-agnostic, occasionally a driver may want to interact with the low-level transport that a device is connected through. To do this, we need to know what kind of bus is in use. The first guess may be to look at the 'bus' field of the 'struct hid_device', but this field may be emulated in some cases (e.g. uhid). More ideally, we can check which ll_driver a device is using. This function introduces a 'hid_is_using_ll_driver' function and makes the 'struct hid_ll_driver' of the four most common transports accessible through hid.h.

HID: betop: fix slab-out-of-bounds Write in betop_probe

commit 1e4ce418b1cb1a810256b5fb3fd33d22d1325993 upstream. Syzbot reported slab-out-of-bounds Write bug in hid-betopff driver.
