2024-10-22selftests: livepatch: rename KLP_SYSFS_DIR to SYSFS_KLP_DIRMichael Vetter
This naming makes more sense according to the directory structure. Especially when we later add more paths. Addtionally replace `/sys/kernel/livepatch` with `$SYSFS_KLP_DIR` in the livepatch test files.

2024-01-22livepatch: Move tests from lib/livepatch to selftests/livepatchMarcos Paulo de Souza
The modules are being moved from lib/livepatch to tools/testing/selftests/livepatch/test_modules. This code moving will allow writing more complex tests, like for example an userspace C code that will call a livepatched kernel function. The modules are now built as out-of-tree modules, but being part of the kernel source means they will be maintained. Another advantage of the code moving is to be able to easily change, debug and rebuild the tests by running make on the selftests/livepatch directory, which is not currently possible since the modules on lib/livepatch are build and installed using the "modules" target. The current approach also keeps the ability to execute the tests manually by executing the scripts inside selftests/livepatch directory, as it's currently supported. If the modules are modified, they needed to be rebuilt before running the scripts though. The modules are built before running the selftests when using the kselftest invocations: make kselftest TARGETS=livepatch or make -C tools/testing/selftests/livepatch run_tests Having the modules being built as out-of-modules requires changing the currently used 'modprobe' by 'insmod' and adapt the test scripts that check for the kernel message buffer. Now it is possible to only compile the modules by running: make -C tools/testing/selftests/livepatch/ This way the test modules and other test program can be built in order to be packaged if so desired. As there aren't any modules being built on lib/livepatch, remove the TEST_LIVEPATCH Kconfig and it's references. Note: "make gen_tar" packages the pre-built binaries into the tarball. It means that it will store the test modules pre-built for the kernel running on the build host. Note that these modules need not binary compatible with the kernel built from the same sources. But the same is true for other packaged selftest binaries. The entire kernel sources are needed for rebuilding the selftests on another system.

2020-06-19selftests/livepatch: Don't clear dmesg when running testsJoe Lawrence
Inspired by commit f131d9edc29d ("selftests/lkdtm: Don't clear dmesg when running tests"), keep a reference dmesg copy when beginning each test. This way check_result() can compare against the initial copy rather than relying upon an empty log.

2019-12-23selftests: livepatch: Fix it to do root uid check and skipShuah Khan
livepatch test configures the system and debug environment to run tests. Some of these actions fail without root access and test dumps several permission denied messages before it exits. Fix test-state.sh to call setup_config instead of set_dynamic_debug as suggested by Petr Mladek <pmladek@suse.com> Fix it to check root uid and exit with skip code instead.
