The helper function produces the value that is returned in *oldlenp.

If you happen to use CTL_DESCRIBE (e.g. running sysctl -d), it's
not your helper function being called but the sysctl_describe helper
that returns a value of 1024.

Maybe you can show your helper routine and how you call sysctl ?
