selftests/clone3: Avoid OS-defined clone_args

2020-10-08T20:17:25+00:00

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outdated versions of struct clone_args to be able to test modern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/cgroup: add tests for cloning into cgroups

2020-02-12T22:57:51+00:00

Expand the cgroup test-suite to include tests for CLONE_INTO_CGROUP.
This adds the following tests:
- CLONE_INTO_CGROUP manages to clone a process directly into a correctly
  delegated cgroup
- CLONE_INTO_CGROUP fails to clone a process into a cgroup that has been
  removed after we've opened an fd to it
- CLONE_INTO_CGROUP fails to clone a process into an invalid domain
  cgroup
- CLONE_INTO_CGROUP adheres to the no internal process constraint
- CLONE_INTO_CGROUP works with the freezer feature

selftests/clone3: skip if clone3() is ENOSYS

2019-11-18T07:59:03+00:00

If the clone3() syscall is not implemented we should skip the tests.

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

2019-11-18T07:57:23+00:00

Buffers have to be flushed before clone3() to avoid double messages in
the log.

selftests: add tests for clone3() with *set_tid

2019-11-15T22:49:51+00:00

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.
