* selftests: lib.mk: copy test scripts and test files for make O=dir runShuah Khan2017-09-211-0/+11
| | | | | | | | | For make O=dir run_tests to work, test scripts, test files, and other dependencies need to be copied over to the object directory. Running tests from the object directory is necessary to avoid making the source tree dirty. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
* selftests: sync: kselftest and kselftest-clean fail for make O=dir caseShuah Khan2017-09-211-6/+18
| | | | | | | | | | sync test fails to build when object directory is specified to relocate object files. Fix it to specify the correct path. Fix clean target to remove objects. Also include simplified logic to use TEST_CUSTOM_PROGS in build and clean targets instead of hard-coding the test name each time. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
* selftests: sync: use TEST_CUSTOM_PROGS instead of TEST_PROGSShuah Khan2017-09-211-2/+4
| | | | | | | | lib.mk var TEST_CUSTOM_PROGS is for tests that need custom build rules. TEST_PROGS is used for test shell scripts. Fix it to use TEST_CUSTOM_PROGS. lib.mk will run and install them. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
* selftests: lib.mk: add TEST_CUSTOM_PROGS to allow custom test run/installShuah Khan2017-09-211-5/+11
| | | | | | | | | | Some tests such as sync can't use generic build rules in lib.mk and require custom rules. Currently there is no provision to allow custom builds and test such as sync use TEST_PROGS which is reserved for test shell scripts. Add TEST_CUSTOM_PROGS variable to lib.mk to run and install custom tests built by individual test make files. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
* selftests: watchdog: fix to use TEST_GEN_PROGS and remove cleanShuah Khan2017-09-211-6/+1
| | | | | | | | | TEST_PROGS should be used for test scripts that don't ned to be built. Use TEST_GEN_PROGS instead which is intended for test executables. Remove clean target and let the common clean take care of cleaning. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>

I delayed it so that a minor conflict resolution with the mips tree could spend a little time in linux-next before I sent this pull request. This includes two long delayed user namespace changes from Kirill Tkhai. It also includes a very useful change from Serge Hallyn that allows the security capability attribute to be used inside of user namespaces. The practical effect of this is people can now untar tarballs and install rpms in user namespaces. It had been suggested to generalize this and encode some of the namespace information information in the xattr name. Upon close inspection that makes the things that should be hard easy and the things that should be easy more expensive. Then there is my bugfix/cleanup for signal injection that removes the magic encoding of the siginfo union member from the kernel internal si_code. The mips folks reported the case where I had used FPE_FIXME me is impossible so I have remove FPE_FIXME from mips, while at the same time including a return statement in that case to keep gcc from complaining about unitialized variables. I almost finished the work to get make copy_siginfo_to_user a trivial copy to user. The code is available at: git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git neuter-copy_siginfo_to_user-v3 But I did not have time/energy to get the code posted and reviewed before the merge window opened. I was able to see that the security excuse for just copying fields that we know are initialized doesn't work in practice there are buggy initializations that don't initialize the proper fields in siginfo.

Per the rationale in 67a3e8fe9015 ("nd_blk: change aperture mapping from WC to WB"), the only existing use is actually to invalidate clean cache lines for ARCH_MEMREMAP_PMEM type mappings *without* writeback. Since the recent cleanup of the pmem API, that also now happens to be the exact purpose of arch_invalidate_pmem(), which would be a far more well-defined tool for the job. Rather than risk potentially inconsistent implementations of mmio_flush_range() for the sake of one callsite, streamline things by removing it entirely and instead move the ARCH_MEMREMAP_PMEM related definitions up to the libnvdimm level, so they can be shared by NFIT as well. This allows NFIT to be enabled for arm64. Signed-off-by: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

This also adds a series of additional tests to capture detach operation and also attaching/detaching invalid prog types. API note: socks will run (or not run) programs depending on the state of the map at the time the sock is added. We do not for example walk the map and remove programs from previously attached socks.

A few more tests are converted and kselftest common RUN_TESTS in lib.mk is enhanced to print TAP13 to cover test shell scripts that won't be able to use kselftest API. - Several fixes to existing tests to not fail in unsupported cases. This has been an ongoing work based on the feedback from stable release kselftest users. - A new watchdog test and much needed cleanups to the existing tests from Eugeniu Rosca. - Changes to kselftest common lib.mk framework to make RUN_TESTS a function to be called from individual test make files to run stress and destructive sub-tests. * tag 'linux-kselftest-4.14-rc1-update' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: (41 commits) selftests: Enhance kselftest_harness.h to print which assert failed selftests: lib.mk: change RUN_TESTS to print messages in TAP13 format selftests: change lib.mk RUN_TESTS to take test list as an argument selftests: lib.mk: suppress "cd" output from run_tests target selftests: kselftest framework: change skip exit code to 0 selftests/timers: make loop consistent with array size selftests: timers: remove rtctest_setdate from run_destructive_tests selftests: timers: Fix run_destructive_tests target to handle skipped tests kselftests: timers: leap-a-day: Change default arguments to help test runs selftests: timers: drop support for !KTEST case rtc: rtctest: Improve support detection selftests/cpu-hotplug: Skip test when there is only one online cpu selftests/cpu-hotplug: exit with failure when test occured unexpected behaviors selftests: futex: convert test to use ksft TAP13 framework selftests: capabilities: convert error output to TAP13 ksft framework selftests: memfd: Align STACK_SIZE for ARM AArch64 system selftests: warn if failure is due to lack of executable bit selftests: kselftest framework: add error counter selftests: capabilities: convert the test to use TAP13 ksft framework selftests: capabilities: fix to run Non-root +ia, sgidroot => i test ...

This change add TAP13 header at the start of RUN_TESTS target run, and prints the resulting pass/fail messages with test number information in the TAP 13 format for each test in the run tests list. This change covers test scripts as well as test programs. Test programs have an option to use ksft_ API, however test scripts won't be able to. With this change, test scripts can print TAP13 format output without any changes to individual scripts. Test programs can provide TAP13 format output as needed as some tests already do. Tests that haven't been converted will benefit from this change. Tests that are converted benefit from the test counts for all the tests in each test directory.
