capabilities: add a securebit to disable PR_CAP_AMBIENT_RAISE
Per Andrew Morgan's request, add a securebit to allow admins to disable PR_CAP_AMBIENT_RAISE. This securebit will prevent processes from adding capabilities to their ambient set. For simplicity, this disables PR_CAP_AMBIENT_RAISE entirely rather than just disabling setting previously cleared bits. Signed-off-by: Andy Lutomirski <luto@kernel.org> Acked-by: Andrew G.
