selftests/clone3: Avoid OS-defined clone_args

2020-10-08T20:17:25Z

As the UAPI headers start to appear in distros, we need to avoid outdated versions of struct clone_args to be able to test modern features, named "struct __clone_args". Additionally update the struct size macro names to match UAPI names.

selftests/clone3: Reorder reporting output

2020-07-06T21:58:49Z

Selftest output reporting was happening before the TAP headers and plan had been emitted. Move the first test reports later. Acked-by: Christian Brauner Signed-off-by: Kees Cook Signed-off-by: Shuah Khan

selftests/clone3: skip if clone3() is ENOSYS

2019-11-18T07:59:03Z

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

selftests/clone3: check that all pids are released on error paths

2019-11-18T07:57:59Z

This is a regression test case for an issue when pids have not been released on error paths. Signed-off-by: Andrei Vagin Link: https://lore.kernel.org/r/20191118064750.408003-3-avagin@gmail.com Signed-off-by: Christian Brauner

selftests/clone3: report a correct number of fails

2019-11-18T07:57:54Z

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.

selftests/clone3: flush stdout and stderr before clone3() and _exit()

2019-11-18T07:57:23Z

Buffers have to be flushed before clone3() to avoid double messages in the log. Fixes: 41585bbeeef9 ("selftests: add tests for clone3() with *set_tid") Signed-off-by: Andrei Vagin Link: https://lore.kernel.org/r/20191118064750.408003-1-avagin@gmail.com Signed-off-by: Christian Brauner

selftests: add tests for clone3() with *set_tid

2019-11-15T22:49:51Z

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.
