Hi, I would like some feedback on what to do with this Errrata? https://www.rfc-editor.org/errata/eid4826 Errata ID: 4826 Status: Reported Type: Technical Publication Format(s) : TEXT Reported By: Mihály Mészáros Date Reported: 2016-10-10 Section 8. says: 8. STUN Client Behavior o The client looks for the MESSAGE-INTEGRITY attribute in the response. If MESSAGE-INTEGRITY is absent or the value computed for message integrity using mac_key does not match the contents of the MESSAGE-INTEGRITY attribute, then the response MUST be discarded. o If the access token expires, then the client MUST obtain a new token from the authorization server and use it for new STUN requests. It should say: 8. STUN Client Behavior o The client looks for the MESSAGE-INTEGRITY attribute in the response. If MESSAGE-INTEGRITY is absent or the value computed for message integrity using mac_key does not match the contents of the MESSAGE-INTEGRITY attribute, then the response MUST be discarded. 9. Application (OAuth Client) Behavior o If the access token expires, then the Application (OAuth client) MUST obtain a new token from the authorization server, and update STUN client to use it for new STUN requests. o Application SHOULD pass only a subset of the received OAuth parameters to the STUN client. Only parameters SHOULD be passed that will be really needed and used by the STUN Client. In this way, only the kid, the mac_key, and the access_token parameters SHOULD be passed to the STUN client. ... Renumber the sections ... Notes: 1. Remove from STUN client behaviour the access_token renewal function, and move this function up to application level. 2. Pass to STUN only that subset of the OAuth parameters, that will be really used by STUN Client.
