And this is the last(?) revision of this series which should now compile with or without CONFIG_HID_BPF set. I had to do changes because [1] was failing Nick, I kept your Tested-by, even if I made small changes in 1/3. Feel free to shout if you don't want me to keep it. Eduard, You helped us a lot in the review of v1 but never sent your Reviewed-by or Acked-by. Do you want me to add one? Cheers, Benjamin [1] https://gitlab.freedesktop.org/bentiss/hid/-/jobs/49754306 For reference, the v2 cover letter: | Hi, I am sending this series on behalf of myself and Benjamin Tissoires. There | existed an initial n=3 patch series which was later expanded to n=4 and | is now back to n=3 with some fixes added in and rebased against | mainline. | | This patch series aims to ensure that the hid/bpf selftests can be built | without errors. | | Here's Benjamin's initial cover letter for context: | | These fixes have been triggered by [0]: | | basically, if you do not recompile the kernel first, and are | | running on an old kernel, vmlinux.h doesn't have the required | | symbols and the compilation fails. | | | | The tests will fail if you run them on that very same machine, | | of course, but the binary should compile. | | | | And while I was sorting out why it was failing, I realized I | | could do a couple of improvements on the Makefile. | | | | [0] https://lore.kernel.org/linux-input/56ba8125-2c6f-a9c9-d498-0ca1c153dcb2@xxxxxxxxxx/T/#t Signed-off-by: Benjamin Tissoires <bentiss@xxxxxxxxxx> --- Changes in v3: - Also overwrite all of the enum symbols in patch 1/3 - Link to v2: https://lore.kernel.org/r/20230908-kselftest-09-08-v2-0-0def978a4c1b@xxxxxxxxxx Changes in v2: - roll Justin's fix into patch 1/3 - add __attribute__((preserve_access_index)) (thanks Eduard) - rebased onto mainline (2dde18cd1d8fac735875f2e4987f11817cc0bc2c) - Link to v1: https://lore.kernel.org/r/20230825-wip-selftests-v1-0-c862769020a8@xxxxxxxxxx Link: https://github.com/ClangBuiltLinux/linux/issues/1698 Link: https://github.com/ClangBuiltLinux/continuous-integration2/issues/61 --- Benjamin Tissoires (3): selftests/hid: ensure we can compile the tests on kernels pre-6.3 selftests/hid: do not manually call headers_install selftests/hid: force using our compiled libbpf headers tools/testing/selftests/hid/Makefile | 10 ++- tools/testing/selftests/hid/progs/hid.c | 3 - .../testing/selftests/hid/progs/hid_bpf_helpers.h | 77 ++++++++++++++++++++++ 3 files changed, 81 insertions(+), 9 deletions(-) --- base-commit: 29aa98d0fe013e2ab62aae4266231b7fb05d47a2 change-id: 20230825-wip-selftests-9a7502b56542 Best regards, -- Benjamin Tissoires <bentiss@xxxxxxxxxx>
