2019-11-18	selftests/clone3: skip if clone3() is ENOSYS	Christian Brauner	4	-30/+33
	If the clone3() syscall is not implemented we should skip the tests. Fixes: 41585bbeeef9 ("selftests: add tests for clone3() with *set_tid") Fixes: 17a810699c18 ("selftests: add tests for clone3()") Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com>
2019-11-18	selftests/clone3: check that all pids are released on error paths	Andrei Vagin	1	-2/+14
	This is a regression test case for an issue when pids have not been released on error paths. Signed-off-by: Andrei Vagin <avagin@gmail.com> Link: https://lore.kernel.org/r/20191118064750.408003-3-avagin@gmail.com Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com>
2019-11-18	selftests/clone3: report a correct number of fails	Andrei Vagin	1	-7/+3
	In clone3_set_tid, a few test cases are running in a child process. And right now, if one of these test cases fails, the whole test will exit with the success status.

2019-11-18	selftests/clone3: flush stdout and stderr before clone3() and _exit()	Andrei Vagin	2	-4/+13
	Buffers have to be flushed before clone3() to avoid double messages in the log.

2019-11-15	selftests: add tests for clone3() with *set_tid	Adrian Reber	6	-26/+421
	This tests clone3() with *set_tid to see if all desired PIDs are working as expected. The tests are trying multiple invalid input parameters as well as creating processes while specifying a certain PID in multiple PID namespaces at the same time. Additionally this moves common clone3() test code into clone3_selftests.h.

2019-11-12	selftests: add tests for clone3()	Adrian Reber	3	-2/+208
	This adds tests for clone3() with different values and sizes of struct clone_args. This selftest was initially part of of the clone3() with PID selftest. After that patch was almost merged Eugene sent out a couple of patches to fix problems with these test. This commit now only contains the clone3() selftest after the LPC decision to rework clone3() with PID to allow setting the PID in multiple PID namespaces including all of Eugene's patches.

2019-10-21	tests: test CLONE_CLEAR_SIGHAND	Christian Brauner	3	-0/+179
	Test that CLONE_CLEAR_SIGHAND resets signal handlers to SIG_DFL for the child process and that CLONE_CLEAR_SIGHAND and CLONE_SIGHAND are mutually exclusive.
