Largely inspired from hid_bpf.c for the fixture setup. Create a couple of tests for hidraw: - create a uhid device and check if the fixture is working properly - inject one uhid event and read it through hidraw These tests are not that useful for now, but will be once we start adding the ioctl and BPFs to revoke the hidraw node.

Since commit 08ac454e258e ("libbpf: Auto-attach struct_ops BPF maps in BPF skeleton"), libbpf automatically calls bpf_map__attach_struct_ops() on every struct_ops it sees in the bpf object. The problem is that our test bpf object has many of them but only one should be manually loaded at a time, or we end up locking the syscall.

In the same way than commit ae7487d112cf ("selftests/hid: ensure we can compile the tests on kernels pre-6.3") we should expose struct hid_bpf_ops when it's not available in vmlinux.h. So unexpose an eventual struct hid_bpf_ops, include vmlinux.h, and re-export struct hid_bpf_ops.

Similar to test_multiply_events_wq: we receive one event and inject a new one. But given that this time we are already in the event hook, we can use hid_bpf_try_input_report() directly as this function will not sleep. Note that the injected event gets processed before the original one this way.

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: convert the primary button testsBenjamin Tissoires1-95/+65
We get more descriptive in what we are doing, and also get more information of what is actually being tested. Instead of having a non exhaustive button changes that are semi-randomly done, we can describe all the states we want to test.

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.

Those transitions have nothing to do with `Pen`, so migrate them to `PenState`. The hidden agenda is to remove `Pen` and integrate it into `PenDigitizer` so that we can tweak the events in each state to emulate firmware bugs.
