Subject: [PATCH 14/15] selftests/clone3: Avoid OS-defined clone_args
Date: Sat, 12 Sep 2020 04:08:19 -0700	[thread overview]
Message-ID: <20200912110820.597135-15-keescook@chromium.org> (raw)
In-Reply-To: <20200912110820.597135-1-keescook@chromium.org>

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outdated versions of struct clone_args to be able to test modern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. Additionally pull in the syscall numbers correctly.

Signed-off-by: Kees Cook <keescook@chromium.org>

I needed to fix this to get MIPS to build the seccomp selftests.
