[Uta] Review of, and recommendation to adopt, draft-tschofenig-uta-tls13-profile

[Barry Leiba <[e-mail]>]

I think draft-tschofenig-uta-tls13-profile represents work that UTA
should take on, and that it is a good starting point for the working
group to use.

Review of version -01:

Section 2: Please change to the RFC 8174 boilerplate and add a
normative reference to RFC 8174.

Section 3, last paragraph: a nit, but I would change this to active voice:
NEW
   TLS/DTLS clients and servers implementing raw public keys and/or
   certificates MUST follow the guidance for mandatory-to-implement
   extensions described in Section 9.2 of [RFC8446].
END

Section 4: The last sentence has a typo and doesn’t make sense.  I
think you mean this:
NEW
   Hence, it is more
   important for a developer to find out from which situations the
   device can recover and which situations are hopeless.
END

(And you might consider whether the word “more” is actually useful.)

For Sections 8, 9, 10, 13, and 14 (and the first paragraph of Section
3), we should consider whether this document should be stand-alone
(consider a future when TLS 1.3 is ubiquitous and 1.2 fades away), and
copy the text from 7925 rather than refer to it, even though that
makes this document longer.  One could do that along with adding a
note that the RFC Editor will remove, which says that the text is
verbatim from RFC 7925, to help reviewers.

Section 9: Change “this document” to “that document”.

Section 10: Nit… “any more” should be two words.

Section 15:
draft-ietf-http-replay is now RFC 8470, published in September.

Another unnecessary passive voice to change to active:
OLD
   It is RECOMMENDED that origin servers allow resources to explicitly
   configure whether early data is appropriate in requests.
NEW
   Origin servers SHOULD allow resources to explicitly
   configure whether early data is appropriate in requests.
END

You say, ‘This specification defines a new CoAP option "timestamp" ‘.
Why is that defined in Appendix A, and not here in Section 15?
