Re: [Last-Call] [dtn] Last Call: <draft-ietf-dtn-bpbis-30.txt> (Bundle Protocol Version 7) to Proposed Standard

[Brian Sipos <BSipos@xxxxxxxxxxx>]

All,

While using the BPv7 CDDL for a BPSec demo implementation I found two minor typos in the CDDL content Appendix B:

1. The socket for extension blocks is:
   

      extension-block = $extension-block-structure .within canonical-block-structure

   but should be for consistency:
   

      extension-block = $extension-block .within canonical-block-structure

   This would also apply to uses of the extension-block socket.
   
2. The block-type-specific data is nominally encoded CBOR, but in the case of BCB encrypted data is purely ciphertext and not decodable. So where is now:
   

      embedded-cbor<Item> = (bstr .cbor Item) / #6.24(bstr .cbor Item)

   to allow pure ciphertext it should be:
   

      ; Additional plain bstr allows ciphertext data.
      embedded-cbor<Item> = (bstr .cbor Item) / #6.24(bstr .cbor Item) / bstr

   This last item is more nitpicky but is necessary for encrypted blocks to pass CDDL validation.
   

Both of these changes are present in the extracted CDDL at [1].

Subject: [dtn] Last Call: <draft-ietf-dtn-bpbis-30.txt> (Bundle Protocol Version 7) to Proposed Standard

 

The IESG has received a request from the Delay/Disruption Tolerant Networking
WG (dtn) to consider the following document: - 'Bundle Protocol Version 7'
  <draft-ietf-dtn-bpbis-30.txt> as Proposed Standard

This is a second IETF last call due to extensive changes since previous IETF
last call.

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@xxxxxxxx mailing lists by 2021-01-18. Exceptionally, comments may
be sent to iesg@xxxxxxxx instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract


   This Internet Draft presents a specification for the Bundle
   Protocol, adapted from the experimental Bundle Protocol
   specification developed by the Delay-Tolerant Networking Research
   group of the Internet Research Task Force and documented in RFC
   5050.
