Hi I reviewed the draft and here are a few comments: “The PADDING octects MUST be set to 0x00. If a Responder detects non- 0x00 octects in the padding of a query, a FORMERR (RCODE=1) MUST be returned.”
è Is MUST necessary here? There might be existing responders that may be agnostic to this and not parse this option code. They may not return Formerr. For quick adoption changing this to SHOULD or providing option to ignore this will be useful. è What is the guidance for the proxy systems used in front of DNS servers (load balancer or traffic managers)? Should they be validating this option for correctness or be plain tunnels? è What if the packet does not have space to pad? Do we have a Padding option with length 0? Or we truncate messages? The 'Padding' option MUST occur at most once per OPT meta-RR. è Is not there only one OPT RR per packet? There can be multiple option IDs but RR is only one. Just checking if the statement above is semantically correct. Also, +1 for approval Thanks Ashu Microsoft From: dns-privacy [mailto:[email protected]] On Behalf Of Alex Mayrhofer Sent: Thursday, November 5, 2015 9:21 AM To: [email protected]; Tim WIcinski <[email protected]> Subject: Re: [dns-privacy] Call for Adoption: draft-mayrhofer-edns0-padding I've submitted a -00 WG version of the draft, which is now pending WG Chairs approval. Hope I got everything right, since the draft was edited from a phone onboard a ferry with crappy wifi and while coloring a pirates book with a 3yo ;-) Alex ---- Tim Wicinski schrieb ---- During the meeting on Monday, it was obvious the Working Group wanted to make this an official EDNS option. We reached out to the author and while he is traveling for an extended period of time, he is happy to work on edits (with a small delay built in, but nothing this impatient chair finds too onerous).
