Checking for RLIM_INFINITY is wrong here, since it is ulong long max,
considering
arg = va_arg(ap, long);
and ulimit(3) stating that arg is always plain long.
Proper check will be
if (arg < 0) {
errno = EINVAL;
return (-1);
}
if (arg > LONG_MAX / 512)
arg = LONG_MAX / 512;
That all. In pure theoretical case RLIM_INFINITY is less than LONG_MAX,
it is job of underlying setrlimit(2) to return error.
