[secdir] Review of draft-levin-mmusic-xml-media-control-12
Hello, I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. Overall as an informational ID I believe the document is well written and it should be published as soon as possible. I have the following non-blocking COMMENTS: 1. Section 2, inconsistent use of RFC2119 language, shipping products and new products SHALL use ..., the preceding sentence seems to suggest it is a SHOULD not a SHALL. 2. Section 4, the inconsistently spelling of in time vs in-time. Not being an expert in this field, it is not clear to me what the parenthesis actually adds. 3. Section 4, (what I consider) incorrect use of RFC2119 language, ... MUST be validated by ..., I do not know what does the use of MUST imply here. Suggestion: it should be sufficient to drop the MUST keyword here, try is validated 4. Section 5, the UAC that sent..., please expand UAC on first use. 5. section 7, unclear statement, Note that this primitive is supported by all known implementations, it is not clear to me which primitive it refers to. Suggestion: quote a reference for the primitive in question. 6. section 10, overall this section could benefit from more details or references. For example, it is not clear how TLS can be applied to secure the signalling path. Also the last sentence seems to contradict with the rest of this section. The section in RFC2976 only explicitly mentions confidentiality. Suggestion: it might be sufficient to say the security considerations in RFC2976 apply here.

[secdir] Review of draft-ietf-enum-calendar-service-03
Hello, I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. I have the following COMMENTS: 1. Overall, the document does not discuss I18N. Is it required that the mailto contains US ASCII only when it is encoded in DNS? This is unclear to me. 2. Section 4, what is the security implication if the same number is used to identify different URIs. In other words, what prevents the choice of numbers from collisions and what happens when there is a collision. Number squatting does not seem to be mitigated by DNS SEC as mentioned in the document. This is just not clear to me but I am not an expert here. 3. I agree with the comments that adding some description of potential use cases would help when the PROTO write-up mentions there is no implementation interest. For one thing, security considerations typically would make more sense in the context of use cases. Best regards, --larry ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf
Call for Comment: RFC 4693 experiment
RFC 4693, Section 4 says: This experiment is expected to run for a period of 12 months, starting from the date of the first ION published using this mechanism. At the end of the period, the IESG should issue a call for comments from the community, asking for people to state their agreement to one of the following statements (or a suitable reformulation thereof): According to http://www.ietf.org/IESG/content/ions/ the first ION was published 12-Jan-2007. This means the experiment ended last Saturday, and it's time for the IESG to issue the call for comments. Please tell us what you think about the experiment. Have IONs been valuable? Should we continue to make use of this mechanism? ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf

That's undoubtedly true - in fact they would need to be the normal way we post procedural stuff to the web site (i.e. things like http://www.ietf.org/ietf/1id-guidelines.html should be IONs). If we are to make IONs permanent, I'd want to see them better integrated in the web site as a whole, rather than being hidden in a corner at http://www.ietf.org/IESG/content/ions.html. Just as a reminder, the idea was to have something *easier and cheaper* than RFCs but more organized than arbitrary web pages. Fred might note that cheaper with his IAOC hat on ;-).

Harald: This is my reservation as well. The ION process has not been as light-weight as I would like. Frankly, it is easier to generate an IESG Statement than an ION.

On Thu, 17 Jan 2008, Mark Andrews wrote: a) when RFC 2821 was written IPv6 existed and RFC 2821 acknowledged its existance. It did DID NOT say synthesize from . RFC 2821 only talks about IPv6 domain literals. The MX resolution algorithm in section 5 is written as if in complete ignorance of IPv6 so it is reasonable to interpret it in the way that RFC 3974 does. If you wanted to rule out MX synthesis from then it should have been written down ten years ago. It's too late now. We 99.9% of the time write down what we should do. We very rarely write down what we shouldn't do. Just because *you* think it was written in complete ignoranance doesn't mean that it was. If you follow what is written down there NOTHING breaks. If you think you know better then things break. They have already been upgraded in this way. Even without fallback-to- , they have to be upgraded to handle IPv6 anyway, because the IPv4 MX lookup algorithm breaks as I described in http://www1.ietf.org/mail-archive/web/ietf/current/msg49843.html MX additional section is a optimization. The lack of or A records is NOT a bug. Perhaps you could explain why the problem I described in the URL above isn't actually a problem. It is not as problem. Additional records have ALWAYS been optional. Any MTA that doesn't look for address records if they are missing from the additional section is *broken* and won't work in a pure IPv4 world let alone a mixed IPv4/IPv6 world. The few cases where there have been such MTA's they get fixed / replaced because they fail to deliver email. I've seen reports that a nameserver was broken because it failed to add additional records (usually because they were not in the cache). Once you point out that it is the MTA that is broken that is the last of the complaint. There will always be developers that fail to read the specifications. When the complaint comes that something is broken you bring out the specification and point out the fault.

Re: I-D Action:draft-hoffman-tao4677bis-00.txt
Added sentences to section 8.1 explaining that BCPs and FYIs are sub- series of Informational RFCs. Namely: The sub-series of FYIs and BCPs are comprised of Informational documents in the sense of the enumeration above, with special tagging applied. That's certainly true of the FYI series (which I believe the RFC Editor regards as dormant today). It absolutely is not true of the BCP series - they are single-stage normative documents, and not a subset of Informational documents. If there's text in RFC 2026 that implies otherwise, I need to update draft-carpenter-rfc2026-changes again. Brian ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf

Brian mentioned about FYIs: | which I believe the RFC Editor regards as dormant today RFC 4949 is now FYI 36, replacing RFC 2828. Is FYI simply a kind of 'informational favourites' picked by the rfc-editor.org folks ? About the TAO, I consider it as the nice or social version of Procdoc, where Procdoc is the emily postnews or marauder's map of the IETF for those who found that nice doesn't cut it. If the TAO tries to stay up to date with say the forever changing boilerplates of IPR maybe it should be also an ION (like Procdoc). The idea of IONs is to get official snapshots of changing details in the standards process not relevant for the Internet at large (incl. IANA), isn't it ? Or maybe TAO is the IETF user manual and public FAQ, while IONs not limited to Procdoc are the reference manual for folks trying to figure out why user manual and implementation are different.

Document Action: 'IPFIX Implementation Guidelines' to Informational RFC
The IESG has approved the following document: - 'IPFIX Implementation Guidelines ' draft-ietf-ipfix-implementation-guidelines-08.txt as an Informational RFC This document is the product of the IP Flow Information Export Working Group. The IESG contact persons are Dan Romascanu and Ron Bonica. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-ipfix-implementation-guidelines-08.txt Technical Summary The IP Flow Information eXport (IPFIX) protocol defines how IP Flow information can be exported from routers, measurement probes or other devices. This document provides guidelines for the implementation and use of the IPFIX protocol. Several sets of guidelines address template management, transport-specific issues, implementation of exporting and collecting processes and IPFIX implementation on middleboxes (such as firewalls, network address translators, tunnel endpoints, packet classifiers, etc.). Working Group Summary This document records experience gained in three IPFIX interopability events. Some of that early experience gave rise to changes in the IPFIX protocol, later experience came in testing IPFIX over its three transports. Overall, this document provides in-depth discussion about IPFIX. It will be useful to implementors and to others wanting more detail about its implementation. The Working Group has reached consensus on this document. Protocol Quality This document addresses implementation and interoperablity issues based on implementations of the IPFIX protocol and interoperability events. The document was reviewed by the WG chairs, by Dan Romascanu on behalf of the IESG, by David Black on behalf of the Transport Directorate, and by Elwyn Davies on behalf of the Gen-Art team. ___ IETF-Announce mailing list IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
