selftest: hid: add the missing tests directory

2024-10-22T13:51:24+00:00

commit fe05c40ca9c18cfdb003f639a30fc78a7ab49519 upstream.

Commit 160c826b4dd0 ("selftest: hid: add missing run-hid-tools-tests.sh")
has added the run-hid-tools-tests.sh script for it to be installed, but
I forgot to add the tests directory together.

If running the test case without the tests directory,  will results in
the following error message:

    make -C tools/testing/selftests/ TARGETS=hid install \
	    INSTALL_PATH=$KSFT_INSTALL_PATH
    cd $KSFT_INSTALL_PATH
    ./run_kselftest.sh -t hid:hid-core.sh

  /usr/lib/python3.11/site-packages/_pytest/config/__init__.py:331: PluggyTeardownRaisedWarning: A plugin raised an exception during an old-style hookwrapper teardown.
  Plugin: helpconfig, Hook: pytest_cmdline_parse
  UsageError: usage: __main__.py [options] [file_or_dir] [file_or_dir] [...]
  __main__.py: error: unrecognized arguments: --udevd
    inifile: None
    rootdir: /root/linux/kselftest_install/hid

In fact, the run-hid-tools-tests.sh script uses the scripts in the tests
directory to run tests. The tests directory also needs to be added to be
installed.

selftest: hid: add missing run-hid-tools-tests.sh

2024-10-10T10:03:41+00:00

[ Upstream commit 160c826b4dd0d570f0f51cf002cb49bda807e9f5 ]

HID test cases run tests using the run-hid-tools-tests.sh script.
When installed with "make install", the run-hid-tools-tests.sh
script will not be copied over, resulting in the following error message.

  make -C tools/testing/selftests/ TARGETS=hid install \
  	  INSTALL_PATH=$KSFT_INSTALL_PATH

  cd $KSFT_INSTALL_PATH
  ./run_kselftest.sh -c hid

selftests: hid: hid-core.sh
bash: ./run-hid-tools-tests.sh: No such file or directory

Add the run-hid-tools-tests.sh script to the TEST_FILES in the Makefile
for it to be installed.

selftests/hid: add test for attaching multiple time the same struct_ops

2024-07-24T16:27:22+00:00

Turns out that we would en up in a bad state if we attempt to attach
twice the same HID-BPF struct_ops, so have a test for it.

selftests/hid: disable struct_ops auto-attach

2024-07-24T16:27:21+00:00

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.

selftests/hid: fix bpf_wq new API

2024-07-24T16:27:21+00:00

Since commit f56f4d541eab ("bpf: helpers: fix bpf_wq_set_callback_impl
signature"), the API for bpf_wq changed a bit.

We need to update the selftests/hid code to reflect that or the
bpf program will not load.

selftests/hid: ensure CKI can compile our new tests on old kernels

2024-07-01T12:48:03+00:00

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.

selftests/hid: add an infinite loop test for hid_bpf_try_input_report

2024-06-27T09:00:49+00:00

We don't want this call to allow an infinite loop in HID-BPF, so let's
have some tests.

selftests/hid: add another test for injecting an event from an event hook

2024-06-27T09:00:49+00:00

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.

selftests/hid: add wq test for hid_bpf_input_report()

2024-06-27T09:00:48+00:00

Now that bpf_wq is available, we can write a test with it. Having
hid_bpf_input_report() waiting for the device means that we can
directly call it, and we get that event when the device is ready.

selftests/hid: add tests for hid_hw_output_report HID-BPF hooks

2024-06-27T09:00:48+00:00

We add 3 new tests:
- first, we make sure we can prevent the output_report to happen
- second, we make sure that we can detect that a given hidraw client
  was actually doing the request, and for that client only, call ourself
  hid_bpf_hw_output_report(), returning a custom value
- last, we ensure that we can not loop between hooks for
  hid_hw_output_report() and manual calls to hid_bpf_hw_output_report()
  from that same hook
