Hi,
During the discussions in Prague, we had good agreement about the following change to the bis. This is a change to the wire protocol. Please say as soon as possible if you disagree with this change, otherwise we'll go ahead and make this change:-

Remove address identifier from MP-PRIO, as it can be used as an attack.

Explanation at https://mailarchive.ietf.org/arch/msg/multipathtcp/WWWaQ3AKWEMgsBSPKc_R9Ct_YoI and follow up emails. The issue was briefly summarised during the Friday meeting in Prague - eg see the etherpad for a summary http://etherpad.tools.ietf.org:9000/p/notes-ietf-99-mptcp?useMonospaceFont=true

Alan - are you ok to make this change please?

--

In addition, we agreed in principle to the following (informational) changes to the bis - exact text to be proposed.

2.       Guidance about MPTCP & TFP interactions, based on https://www.ietf.org/proceedings/99/slides/slides-99-mptcp-sessb-mptcp-tfo-00.pdf - Christoph & Olivier, please propose text.

3.       There was a suggestion, arising from the hackathon, to discuss on the list whether clarifications or extra 'reason codes' would be useful in the context of reset option. Quentin (& others), please make a proposal.
Best wishes,
Phil & Yoshi
