2019-04-25selftests: Add test plan API to kselftest.h and adjust callersKees Cook1-0/+8
The test plan for TAP needs to be declared immediately after the header. This adds the test plan API to kselftest.h and updates all callers to declare their expected test counts. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
2018-05-30selftests: breakpoints: return Kselftest Skip code for skipped testsShuah Khan (Samsung OSG)1-1/+5
When step_after_suspend_test is skipped because of unmet dependencies and/or unsupported configuration, it exits with error which is treated as a fail by the Kselftest framework. This leads to false negative result even when the test could not be run. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Change it to use ksft_exit_skip() when a non-root user runs the test and add an explicit check for root and a clear message, instead of failing the test when /sys/power/state file open fails.

2017-06-30selftests: breakpoints: step_after_suspend_test use ksft_* var arg msg apiShuah Khan1-26/+33
Use ksft_* var arg msg to include strerror() info. in test output and simplify test_result and exit_* using var arg msg api. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
2017-06-15kselftest: make callers of ksft_exit_skip() output the reason for skippingPaul Elder1-2/+2
Make the three tests that did use the old ksft_ext_skip() (breakpoints/breakpoint_test_arm64, breakpoints/step_after_suspend_test, and membarrier_test) use the new one, with an output for the reason for skipping all the tests.

2016-02-25selftests: breakpoint: add step_after_suspend_testGreg Hackmann1-0/+218
Commit e56d82a11617 ("arm64: cpu hotplug: ensure we mask out CPU_TASKS_FROZEN in notifiers") fixed a long-standing ARM64 bug that broke single-stepping after a suspend/resume cycle. Add a kernel selftest to make sure this doesn't regress or affect other platforms. Signed-off-by: Greg Hackmann <ghackmann@google.com> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
