HID: bpf: add HID-BPF hooks for hid_hw_raw_requests
This allows to intercept and prevent or change the behavior of
hid_hw_raw_request() from a bpf program.
The intent is to solve a couple of use case:
- firewalling a HID device: a firewall can monitor who opens the hidraw
nodes and then prevent or allow access to write operations on that
hidraw node.
- change the behavior of a device and emulate a new HID feature request
The hook is allowed to be run as sleepable so it can itself call
hid_bpf_hw_request(), which allows to "convert" one feature request into
another or even call the feature request on a different HID device on the
same physical device.
