selftests/ipc: Fix test failure seen after initial test run

2020-05-10T08:26:10Z

[ Upstream commit b87080eab4c1377706c113fc9c0157f19ea8fed1 ] After successfully running the IPC msgque test once, subsequent runs result in a test failure: $ sudo ./run_kselftest.sh TAP version 13 1..1 # selftests: ipc: msgque # Failed to get stats for IPC queue with id 0 # Failed to dump queue: -22 # Bail out! # # Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0 not ok 1 selftests: ipc: msgque # exit=1 The dump_queue() function loops through the possible message queue index values using calls to msgctl(kern_id, MSG_STAT, ...) where kern_id represents the index value. The first time the test is ran, the initial index value of 0 is valid and the test is able to complete. The index value of 0 is not valid in subsequent test runs and the loop attempts to try index values of 1, 2, 3, and so on until a valid index value is found that corresponds to the message queue created earlier in the test. The msgctl() syscall returns -1 and sets errno to EINVAL when invalid index values are used. The test failure is caused by incorrectly comparing errno to -EINVAL when cycling through possible index values. Fix invalid test failures on subsequent runs of the msgque test by correctly comparing errno values to a non-negated EINVAL.

selftests/ftrace: Fix to test kprobe $comm arg only if available

[ Upstream commit 2452c96e617a0ff6fb2692e55217a3fa57a7322c ] Test $comm in kprobe-event argument syntax testcase only if it is supported on the kernel because $comm has been introduced 4.8 kernel.

selftests: Move networking/timestamping from Documentation

2018-12-17T20:55:17Z

commit 3d2c86e3057995270e08693231039d9d942871f0 upstream. Remove networking from Documentation Makefile to move the test to selftests. Update networking/timestamping Makefile to work under selftests. These tests will not be run as part of selftests suite and will not be included in install targets. They can be built and run separately for now. This is part of the effort to move runnable code from Documentation.

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

2018-09-26T06:35:09Z

[ 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.
