I do not pretend I understand the security ;) For example. I simply can't understand why do we have security_task_wait(). Why waitpid(my_natural_child) can fail for security reasons? But we have selinux_task_wait(). So, once again. I am not arguing. I am only asking the questions. I didn't mean I see any problem here.
