selftests/net: correct the return value for run_netsocktests

2019-05-16T17:45:06Z

[ Upstream commit 30c04d796b693e22405c38e9b78e9a364e4c77e6 ] The run_netsocktests will be marked as passed regardless the actual test result from the ./socket: selftests: net: run_netsocktests ======================================== -------------------- running socket test -------------------- [FAIL] ok 1..6 selftests: net: run_netsocktests [PASS] This is because the test script itself has been successfully executed. Fix this by exit 1 when the test failed. Signed-off-by: Po-Hsu Lin Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

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.

selftests/powerpc: Kill child processes on SIGINT

2018-09-15T07:40:39Z

[ Upstream commit 7c27a26e1ed5a7dd709aa19685d2c98f64e1cf0c ] There are some powerpc selftests, as tm/tm-unavailable, that run for a long period (>120 seconds), and if it is interrupted, as pressing CRTL-C (SIGINT), the foreground process (harness) dies but the child process and threads continue to execute (with PPID = 1 now) in background. In this case, you'd think the whole test exited, but there are remaining threads and processes being executed in background. Sometimes these zombies processes are doing annoying things, as consuming the whole CPU or dumping things to STDOUT. This patch fixes this problem by attaching an empty signal handler to SIGINT in the harness process. This handler will interrupt (EINTR) the parent process waitpid() call, letting the code to follow through the normal flow, which will kill all the processes in the child process group. This patch also fixes a typo. Signed-off-by: Breno Leitao Signed-off-by: Gustavo Romero Signed-off-by: Michael Ellerman Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

selftests/ftrace: Add snapshot and tracing_on test case

[ Upstream commit 82f4f3e69c5c29bce940dd87a2c0f16c51d48d17 ] Add a testcase for checking snapshot and tracing_on relationship. This ensures that the snapshotting doesn't affect current tracing on/off settings.

selftests/x86/sigreturn/64: Fix spurious failures on AMD CPUs

2018-08-24T11:26:56Z

[ Upstream commit ec348020566009d3da9b99f07c05814d13969c78 ] When I wrote the sigreturn test, I didn't realize that AMD's busted IRET behavior was different from Intel's busted IRET behavior: On AMD CPUs, the CPU leaks the high 32 bits of the kernel stack pointer to certain userspace contexts. Gee, thanks. There's very little the kernel can do about it. Modify the test so it passes.
