2022-02-04selftests: fixup build warnings in pidfd / clone3 testsAxel Rasmussen1-2/+0
These are some trivial fixups, which were needed to build the tests with clang and -Werror. The following issues are fixed: - Remove various unused variables. - In child_poll_leader_exit_test, clang isn't smart enough to realize syscall(SYS_exit, 0) won't return, so it complains we never return from a non-void function. Add an extra exit(0) to appease it. - In test_pidfd_poll_leader_exit, ret may be branched on despite being uninitialized, if we have !use_waitpid. Initialize it to zero to get the right behavior in that case.

2020-10-08selftests/clone3: Avoid OS-defined clone_argsKees Cook5-41/+38
As the UAPI headers start to appear in distros, we need to avoid outdated versions of struct clone_args to be able to test modern features, named "struct __clone_args".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.

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.

2019-11-12selftests: add tests for clone3()Adrian Reber3-2/+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.
