Converting kselftest output to standard format will help identify run to run differences and pin point failures easily. TAP13 format has been in use for several years and the output is human friendly. Please find the specification: https://testanything.org/tap-version-13-specification.html Credit goes to Tim Bird for recommending TAP13 as a suitable format, and to Grag KH for kick starting the work with help from Paul Elder and Alice Ferrazzi The first phase of the TAp13 conversion is included in this update. Future updates will include updates to rest of the tests. - Masami Hiramatsu fixed ftrace to run on 4.9 stable kernels. - Kselftest documnetation has been converted to ReST format. Document now has a new home under Documentation/dev-tools. - kselftest_harness.h is now available for general use as a result of Mickaël Salaün's work. - Several fixes to skip and/or fail tests gracefully on older releases" * tag 'linux-kselftest-4.13-rc1-update' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: (48 commits) selftests: membarrier: use ksft_* var arg msg api selftests: breakpoints: breakpoint_test_arm64: convert test to use TAP13 selftests: breakpoints: step_after_suspend_test use ksft_* var arg msg api selftests: breakpoint_test: use ksft_* var arg msg api kselftest: add ksft_print_msg() function to output general information kselftest: make ksft_* output functions variadic selftests/capabilities: Fix the test_execve test selftests: intel_pstate: add .gitignore selftests: fix memory-hotplug test selftests: add missing test name in memory-hotplug test selftests: check percentage range for memory-hotplug test selftests: check hot-pluggagble memory for memory-hotplug test selftests: typo correction for memory-hotplug test selftests: ftrace: Use md5sum to take less time of checking logs tools/testing/selftests/sysctl: Add pre-check to the value of writes_strict kselftest.rst: do some adjustments after ReST conversion selftest/net/Makefile: Specify output with $(OUTPUT) selftest/intel_pstate/aperf: Use LDLIBS instead of LDFLAGS selftest/memfd/Makefile: Fix build error selftests: lib: Skip tests on missing test modules ...

| * selftests/capabilities: Fix the test_execve testAndy Lutomirski2017-06-301-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | test_execve does rather odd mount manipulations to safely create temporary setuid and setgid executables that aren't visible to the rest of the system. Those executables end up in the test's cwd, but that cwd is MNT_DETACHed. The core namespace code considers MNT_DETACHed trees to belong to no mount namespace at all and, in general, MNT_DETACHed trees are only barely function. This interacted with commit 380cf5ba6b0a ("fs: Treat foreign mounts as nosuid") to cause all MNT_DETACHed trees to act as though they're nosuid, breaking the test. Fix it by just not detaching the tree. It's still in a private mount namespace and is therefore still invisible to the rest of the system (except via /proc, and the same nosuid logic will protect all other programs on the system from believing in test_execve's setuid bits). While we're at it, fix some blatant whitespace problems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The seccomp/test_harness.h file contains useful helpers to build tests. Moving it to the selftest directory should benefit to other test components. Keep seccomp maintainers for this file.

| * selftests: sync: Skip the test if kernel support is not foundMichael Ellerman2017-06-071-0/+13
| | | | | | | | | | | | | | | | | | | | | | The "Sync framework" test doesn't work if the kernel has no support, obviously. Rather than reporting a failure, check for the kernel support by looking for /sys/kernel/debug/sync/sw_sync, and if not found skip the test.

| * selftests: futex: print testcase-name and PASS/FAIL/ERROR statusNaresh Kamboju2017-06-078-10/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the tests under selftests follow a pattern for their results, which can then be parsed easily by other external tools easily. Though futex tests do print the test results very well, it doesn't really follow the general selftests pattern. This patch makes necessary changes to fix that. Output before this patch: futex_requeue_pi: Test requeue functionality Arguments: broadcast=0 locked=0 owner=0 timeout=0ns Result: PASS Output after this patch: futex_requeue_pi: Test requeue functionality Arguments: broadcast=0 locked=0 owner=0 timeout=0ns selftests: futex-requeue-pi [PASS] Signed-off-by: Naresh Kamboju <naresh.kamboju@linaro.org> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
