2024-05-07selftests/hid: skip tests with HID-BPF if udev-hid-bpf is not installedBenjamin Tissoires1-0/+5
udev-hid-bpf is still not installed everywhere, and we should probably not assume it is installed automatically. Link: https://lore.kernel.org/r/20240506143612.148031-1-bentiss@kernel.org Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Benjamin Tissoires <bentiss@kernel.org>

This tablets gets a lot of things wrong: - the secondary button is reported through Secondary Tip Switch - the third button is reported through Invert We need to add some out of proximity intermediate state when moving back and forth with the eraser mode as it can only be triggered by physically returning the pen, meaning that the tolerated transitions can never happen.

All the *_WITH*BUTTON states were almost identical except for the button itself. I need to add a new device with a third button, and adding a bunch of states is going to be quite cumbersome.

2024-01-04bpfilter: remove bpfilterQuentin Deslandes1-1/+0
bpfilter was supposed to convert iptables filtering rules into BPF programs on the fly, from the kernel, through a usermode helper. The base code for the UMH was introduced in 2018, and couple of attempts (2, 3) tried to introduce the BPF program generate features but were abandoned. bpfilter now sits in a kernel tree unused and unusable, occasionally causing confusion amongst Linux users (4, 5). As bpfilter is now developed in a dedicated repository on GitHub (6), it was suggested a couple of times this year (LSFMM/BPF 2023, LPC 2023) to remove the deprecated kernel part of the project. This is the purpose of this patch.

2023-12-07selftests/hid: tablets: be stricter for some transitionsBenjamin Tissoires1-19/+113
To accommodate for legacy devices, we rely on the last state of a transition to be valid: for example when we test PEN_IS_OUT_OF_RANGE to PEN_IS_IN_CONTACT, any "normal" device that reports an InRange bit would insert a PEN_IS_IN_RANGE state between the 2. This is of course valid, but this solution prevents to detect false releases emitted by some firmware: when pressing an "eraser mode" button, they might send an extra PEN_IS_OUT_OF_RANGE that we may want to filter. So define 2 sets of transitions: one that is the ideal behavior, and one that is OK, it won't break user space, but we have serious doubts if we are doing the right thing. And depending on the test, either ask only for valid transitions, or tolerate weird ones.

2023-12-07selftests/hid: tablets: add variants of states with buttonsBenjamin Tissoires1-13/+160
Turns out that there are transitions that are unlikely to happen: for example, having both the tip switch and a button being changed at the same time (in the same report) would require either a very talented and precise user or a very bad hardware with a very low sampling rate. So instead of manually building the button test by hand and forgetting about some cases, let's reuse the state machine and transitions we have. This patch only adds the states and the valid transitions. The actual tests will be replaced later.

2023-10-11selftests/hid: ensure we can compile the tests on kernels pre-6.3Benjamin Tissoires2-3/+77
For the hid-bpf tests to compile, we need to have the definition of struct hid_bpf_ctx. This definition is an internal one from the kernel and it is supposed to be defined in the generated vmlinux.h. This vmlinux.h header is generated based on the currently running kernel or if the kernel was already compiled in the tree. If you just compile the selftests without compiling the kernel beforehand and you are running on a 6.2 kernel, you'll end up with a vmlinux.h without the hid_bpf_ctx definition. Use the clever trick from tools/testing/selftests/bpf/progs/bpf_iter.h to force the definition of that symbol in case we don't find it in the BTF and also add __attribute__((preserve_access_index)) to further support CO-RE functionality for these tests.

2023-07-09selftests: hid: fix vmtests.sh not running make headersBenjamin Tissoires1-0/+1
According to commit 01d6c48a828b ("Documentation: kselftest: "make headers" is a prerequisite"), running the kselftests requires to run "make headers" first. Do that in "vmtest.sh" as well to fix the HID CI. Link: https://lore.kernel.org/r/20230709-fix-selftests-v1-1-57d0878114cc@kernel.org Signed-off-by: Benjamin Tissoires <bentiss@kernel.org>
2023-06-29bpf: Replace deprecated -target with --target= for ClangFangrui Song1-3/+3
The -target option has been deprecated since clang 3.4 in 2013. Therefore, use the preferred --target=bpf form instead. This also matches how we use --target= in scripts/Makefile.clang.

2023-04-12selftests: hid: import hid-tools usb-crash testsBenjamin Tissoires3-0/+111
These tests have been developed in the hid-tools[0] tree for a while. Now that we have a proper selftests/hid kernel entry and that the tests are more reliable, it is time to directly include those in the kernel tree. This one gets skipped when run by vmtest.sh as we currently need to test against actual kernel modules (.ko), not built-in to fetch the list of supported devices.
