kselftests: timers: freq-step: Update maximum acceptable precision and errors

2019-06-22T09:28:53Z

PTI has a significant impact on precision of the MONOTONIC_RAW clock, which prevents a lot of computers from running the freq-step test. Increase the maximum acceptable precision for the test to not be skipped to 500 nanoseconds. After commit 78b98e3c5a66 ("timekeeping/ntp: Determine the multiplier directly from NTP tick length") the frequency and time errors should be much smaller. Reduce the maximum acceptable values for the test to pass to 0.02 ppm and 50 nanoseconds respectively.

selftests/timers: Add missing fflush(stdout) calls

2019-05-21T15:24:31Z

When running under a pipe, some timer tests would not report output in real-time because stdout flushes were missing after printf()s that lacked a newline. This adds them to restore real-time status output that humans can enjoy. Signed-off-by: Kees Cook Signed-off-by: Shuah Khan

selftest: timers: Tweak raw_skew to SKIP when ADJ_OFFSET/other clock adjustments are in progress

2018-07-10T19:43:21Z

In the past we've warned when ADJ_OFFSET was in progress, usually caused by ntpd or some other time adjusting daemon running in non steady sate, which can cause the skew calculations to be incorrect. Thus, this patch checks to see if the clock was being adjusted when we fail so that we don't cause false negatives.
