selftests: timers: Fix run_destructive_tests target to handle skipped tests

2017-09-13T21:20:53Z

commit df9c011c0a23cf1399c01f896cd359d932ab49b5 upstream. When a test exits with skip exit code of 4, "make run_destructive_tests" halts testing. Fix run_destructive_tests target to handle error exit codes. Reported-by: John Stultz Signed-off-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman

Merge tag 'rtc-4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni: "Here is the pull-request for the RTC subsystem for 4.13. Subsystem: - expose non volatile RAM using nvmem instead of open coding in many drivers. Unfortunately, this option has to be enabled by default to not break existing users. - rtctest can now test for cutoff dates, showing when an RTC will start failing to properly save time and date. - new RTC registration functions to remove race conditions in drivers Newly supported RTCs: - Broadcom STB wake-timer - Epson RX8130CE - Maxim IC DS1308 - STMicroelectronics STM32H7 Drivers: - ds1307: use regmap, use nvmem, more cleanups - ds3232: temperature reading support - gemini: renamed to ftrtc010 - m41t80: use CCF to expose the clock - rv8803: use nvmem - s3c: many cleanups - st-lpc: fix y2106 bug" * tag 'rtc-4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (51 commits) rtc: Remove wrong deprecation comment nvmem: include linux/err.h from header rtc: st-lpc: make it robust against y2038/2106 bug rtc: rtctest: add check for problematic dates tools: timer: add rtctest_setdate rtc: ds1307: remove ds1307_remove rtc: ds1307: use generic nvmem rtc: ds1307: switch to rtc_register_device rtc: rv8803: remove rv8803_remove rtc: rv8803: use generic nvmem support rtc: rv8803: switch to rtc_register_device rtc: add generic nvmem support rtc: at91rm9200: remove race condition rtc: introduce new registration method rtc: class separate id allocation from registration rtc: class separate device allocation from registration rtc: stm32: add STM32H7 RTC support dt-bindings: rtc: stm32: add support for STM32H7 rtc: ds1307: add ds1308 variant rtc: ds3232: add temperature support ...

tools: timer: add rtctest_setdate

2017-07-09T20:00:54Z

This tool allow to set directly the time and date to a RTC device. Unlike other tools isn't doens't use "struct timeval" or "time_t" so it is safe for 32bits platforms when testing for y2038/2106 bug. Signed-off-by: Benjamin Gaignard Signed-off-by: Alexandre Belloni

kselftests: timers: Add test for frequency step

2017-06-21T05:14:45Z

This test checks the response of the system clock to frequency steps made with adjtimex(). The frequency error and stability of the CLOCK_MONOTONIC clock relative to the CLOCK_MONOTONIC_RAW clock is measured in two intervals following the step. The test fails if values from the second interval exceed specified limits.

selftests: remove CROSS_COMPILE in dedicated Makefile

2017-01-05T20:42:11Z

After previous clean up patches, memfd and timers could get CROSS_COMPILE from tools/testing/selftest/lib.mk. There is no need to preserve these definition. So, this patch remove them. Acked-by: Michael Ellerman Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

selftests: remove duplicated all and clean target

2017-01-05T20:41:35Z

Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to indicate the test program, extended test program and test files. It is easy to understand the purpose of these files. But mix of compiled and uncompiled files lead to duplicated "all" and "clean" targets. In order to remove the duplicated targets, introduce TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled objects. Also, the later patch will make use of TEST_GEN_XXX to redirect these files to output directory indicated by KBUILD_OUTPUT or O. And add this changes to "Contributing new tests(details)" of Documentation/kselftest.txt. Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

kselftests: timers: Add set-tz test case

2016-06-02T22:39:56Z

Mika Westerberg reported a erroneous change in the error checking of settimeofday, so I wanted to add a test to ensure we don't trip over this again.

timers, kselftest: Add 'adjtick' test to validate adjtimex() tick adjustments

2015-10-12T07:51:34Z

Recently a kernel side NTP bug was fixed via the following commit: 2619d7e9c92d ("time: Fix timekeeping_freqadjust()'s incorrect use of abs() instead of abs64()") When the bug was reported it was difficult to detect, except by tweaking the adjtimex tick value, and noticing how quickly the adjustment took: https://lkml.org/lkml/2015/9/1/488 Thus this patch introduces a new test which manipulates the adjtimex tick value and validates that the results are what we expect.

Documentation, split up rtc.txt into documentation and test file

2015-03-25T04:01:58Z

This patch splits rtc.txt into two separate files, one for the documentation itself, and the other for the rtctest.c file. The rtctest file is moved into the kernel tools/testing/selftests/timers directory. This will make automated testing easier. Note that the only difference in the rtc.txt file is that the location of the rtctest.c file has changed.
