kselftest: Add test runner creation script
Currently if we wish to use kselftest to run tests within a kernel module we write a small script to load/unload and do error reporting. There are a bunch of these under tools/testing/selftests/lib/ that are all identical except for the test name. We can reduce code duplication and improve maintainability if we have one version of this. However kselftest requires an executable for each test. We can move all the script logic to a central script then have each individual test script call the main script. Oneliner to call kselftest_module.sh courtesy of Kees, thanks! Add test runner creation script. Convert tools/testing/selftests/lib/*.sh to use new test creation script. Testing ------- Configure kselftests for lib/ then build and boot kernel. Then run kselftests as follows: $ cd /path/to/kernel/tree $ sudo make O=$output_path -C tools/testing/selftests TARGETS="lib" run_tests and also $ cd /path/to/kernel/tree $ cd tools/testing/selftests $ sudo make O=$output_path TARGETS="lib" run_tests and also $ cd /path/to/kernel/tree $ cd tools/testing/selftests $ sudo make TARGETS="lib" run_tests Acked-by: Kees Cook <keescook@chromium.org> Signed-off-by: Tobin C.
