Benjamin Tissoires	633ba3be76	selftests: hid: allow to compile hid_bpf with LLVM ... clang doesn't like to compile a source to the final binary directly: clang-14: error: cannot specify -o when generating multiple output files So split the final rule in 2, and ensure we compile all dependencies before.

Benjamin Tissoires	e9d48abbce	kselftests: hid: fix missing headers_install step ... The Makefile was assuming that headers_install was already done in the top source directory, and was searching for installed uapi headers there. Unfortunately this is not the case and we need to manually call that step. To do so, reorder the declaration of the variables, and reuses top_srcdir provided by lib.mk Reported-by: kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/all/202212060216.a6X8Py5H-lkp@intel.com/#t Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Reviewed-by: Jiri Kosina <jkosina@suse.cz> Link: https://lore.kernel.org/r/20221206145936.922196-6-benjamin.tissoires@redhat.com	2022-12-10 10:41:42 +01:00
Benjamin Tissoires	dbb60c8a26	selftests: add tests for the HID-bpf initial implementation ... The tests are pretty basic: - create a virtual uhid device that no userspace will like (to not mess up the running system) - attach a BPF prog to it - open the matching hidraw node - inject one event and check: * that the BPF program can do something on the event stream * can modify the event stream - add another test where we attach/detach BPF programs to see if we get errors Note: the Makefile is extracted from selftests/bpf so we can rebuild the libbpf and bpftool components from the current kernel tree without relying on system installed components.
