Which exact 'cmd' is it here? I _guess_ it is one of those uninitialized in set_arglen[], which is 0. But if that is the case, should it be initialized to sizeof(struct ip_vs_service_user) instead because ip_vs_copy_usvc_compat() is called anyway. Or, maybe we should just ban len==0 case. In either case, it does not look like you fix it correctly. Thanks.
