selftest: hid: fix hid_bpf not set in config

2023-02-23T14:45:25+00:00

Now that CONFIG_HID_BPF is not automatically implied by HID, we need to set it properly in the selftests config. Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

selftests: hid: enforce new attach API

2023-01-18T21:08:38+00:00

Now that the new API for hid_bpf_attach_prog() is in place, ensure we get an fd when calling this function. And remove the fallback code. Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

selftests: hid: prepare tests for HID_BPF API change

2023-01-18T21:08:38+00:00

We plan on changing the return value of hid_bpf_attach_prog(). Instead of returning an error code, it will return an fd to a bpf_link. This bpf_link is responsible for the binding between the bpf program and the hid device. Add a fallback mechanism to not break bisections by pinning the program when we run this test against the non changed kernel. Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

selftests: hid: ensure the program is correctly pinned

2023-01-18T21:08:38+00:00

Turns out that if bpffs was not mounted, the test was silently passing. So ensure it passes by checking the mount command result. Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

selftests: hid: attach/detach 2 bpf programs, not just one

2023-01-18T21:08:38+00:00

Add a second BPF program to attach to the device, as the development of this feature showed that we also need to ensure we can detach multiple programs to a device (hid_bpf_link->hid_table_index was actually not set initially, and this lead to any BPF program not being released except for the first one).

selftests: hid: allow to compile hid_bpf with LLVM

2023-01-18T21:08:38+00:00

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. Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

selftests: hid: add vmtest.sh

2023-01-18T21:08:38+00:00

Similar-ish in many points from the script in selftests/bpf, with a few differences: - relies on boot2container instead of a plain qemu image (meaning that we can take any container in a registry as a base) - runs in the hid selftest dir, and such uses the test program from there - the working directory to store the config is in tools/selftests/hid/results Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

kselftests: hid: fix missing headers_install step

2022-12-10T09:41:42+00:00

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 Link: https://lore.kernel.org/all/202212060216.a6X8Py5H-lkp@intel.com/#t Signed-off-by: Benjamin Tissoires Reviewed-by: Jiri Kosina Link: https://lore.kernel.org/r/20221206145936.922196-6-benjamin.tissoires@redhat.com

selftests: hid: ensures we have the proper requirements in config

DYNAMIC_FTRACE_WITH_DIRECT_CALLS is implicit on x86_64 but is still a WIP on aarm64. Ensure we get it selected to not have any surprises. Signed-off-by: Benjamin Tissoires Reviewed-by: Jiri Kosina Link: https://lore.kernel.org/r/20221206145936.922196-5-benjamin.tissoires@redhat.com

selftests/hid: Add a test for BPF_F_INSERT_HEAD

2022-11-15T15:28:39+00:00

Insert 3 programs to check that we are doing the correct thing: '2', '1', '3' are inserted, but '1' is supposed to be executed first. Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina
