Hi,
This is a series that targets a few HID-BPF issues I discovered or I've
been reported:
- first 2 patches should go to for-7.0/upstream-fixes:
- 1/4 fixes a compilation issue when HID is not enabled
- 2/4 is a nasty bug which allows a HID-BPF to crash the running
kernel, so not critical (you need special permissions to load the
HID-BPF program), but not great as you don't expect tinkering with
HID-BPF would crash
- last 2 patches are more 7.1 material: basically the LEDs on the
keyboards are bypassing HID-BPF, and then that made me realize that
the fallback calls in case of an unnumbered report is not correct (and
likely unnoticed because I don't think I've seen unnumbered reports on
anything else than USB devices)
Cheers,
Benjamin
