[secdir] Review of draft-levin-mmusic-xml-media-control-12

2008-01-17 Thread Larry Zhu
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.

Best regards,

--larry

[secdir] Review of draft-ietf-enum-calendar-service-03

2008-01-17 Thread Larry Zhu
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,

Call for Comment: RFC 4693 experiment

2008-01-17 Thread The IESG
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?

I've been on various IETF mailing lists for a year or two now and  
I've never seen any reference to these ION documents. Obviously there  
must have been and I must have missed it... but I've not had other  
people point me to them, either.  For instance, at IETF 70, I agreed  
to take minutes for one of the sessions and when I asked if there was  
any preferred format, no one pointed me to this ION: http:// 
www.ietf.org/IESG/content/ions/ion-agenda-and-minutes.html


Have now learned of them by this email exchange, some of the  
documents look both interesting and useful, but I'd agree with Fred  
that in order to call the series successful there really need to be  
more people pointing to them and using them.


My 2 cents,

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.

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.

 invalidate some BCPs.

It is, however, clear that they are approved like single-stage standards,
with a required last-call and rough consensus, which doesn't apply
to Informationals.

You may want to check for consistency with RFC 4844 through 4846, too.

Updating the Tao of the IETF

Greetings again. In the year or so since the revised Tao of the IETF 
has come out, a few people have pointed out errors. I have started a

a year to catch up with changes in the IETF (IONs maybe?), then 
submit it for IETF last call.

Sure we can. A BCP is a document that is approved by the IESG as a

They are definitely not informational documents.

...it could be more straight forward than BCPs listed in the

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.

Something along that line, yes. The Tao really should be an RFC, 
which means that it will go out of date regularly. Its intended

For what it's worth, there's a document in the dnsop queue which the

Document Action: 'IPFIX Implementation Guidelines' to Informational RFC

2008-01-17 Thread The IESG
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.
