Why can't handle these strings in array. For example you can define an array of strings for passed unexpectedly etc. and the pass the string to appropriate ksft_* interface instead of adding of these routines. Also it is hard to review the code this way. I would like to see the changes made to membarrier_test.c instead of adding a new file. I do like the direction though. thanks, -- Shuah

[PATCH net-next] selftests/tls: Add MSG_WAITALL in recv() syscall

by Vakul Garg

A number of tls selftests rely upon recv() to return an exact number of data bytes. When tls record crypto is done using an async accelerator, it is possible that recv() returns lesser than expected number bytes. This leads to failure of many test cases. To fix it, MSG_WAITALL has been used in flags passed to recv() syscall.

[PATCH AUTOSEL 4.4 17/20] selftest: timers: Tweak raw_skew to SKIP when ADJ_OFFSET/other clock adjustments are in progress

by Sasha Levin

From: John Stultz <john.stultz(a)linaro.org> [ Upstream commit 1416270f4a1ae83ea84156ceba19a66a8f88be1f ] 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.
