In general I don't think it makes sense to submit stuff for 2.4 
that isn't in 2.6.

In general I agree, however right now I had the choice between
submitting these changes for 2.4 first and not submitting them at all
(at least for some months more).  I chose the former.

If there is really a length checking bug it shouldn't be that hard to fix it 
in both.

There were such length checking bugs being discovered and fixed in the
past.  In particular, many got fixed between 2.2.18 and 2.2.19; that was
also when I added this hardening measure to -ow patches (starting with
2.2.19-ow1 released 5 years ago).

Of course, any known bugs should be fixed ASAP, but to me that is not a
sufficient reason to not keep a hardening measure like this.  It's just
a matter of opinion.
