selftests: add clone3() CAP_CHECKPOINT_RESTORE test This adds a test that changes its UID, uses capabilities to get CAP_CHECKPOINT_RESTORE and uses clone3() with set_tid to create a process with a given PID as non-root.

selftests: fixup build warnings in pidfd / clone3 tests stable inclusion from stable-v5.10.102 commit e05dde47f52a4a8b027be0fa199d1419b2b4fc3c bugzilla: https://gitee.com/openeuler/kernel/issues/I567K6 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e05dde47f52a4a8b027be0fa199d1419b2b4fc3c -------------------------------- [ Upstream commit e2aa5e650b07693477dff554053605976789fd68 ] 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.

selftests/clone3: Avoid OS-defined clone_args As the UAPI headers start to appear in distros, we need to avoid outdated versions of struct clone_args to be able to test modern features, named "struct __clone_args".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