Thanks for the work that went into creating this document. I find no serious issues, and will be requesting IETF last call momentarily. I have included a small number of editorial suggestions below. Please treat them the same as you would any other IETF last call comments. --------------------------------------------------------------------------- §1: >   These solutions don't preclude the use of UE provided location but Nit: "UE-provided" >   "loc-src"."How the entity adding the locationValue to the header Nit: extra quotation mark before "How" --------------------------------------------------------------------------- §3: >    All of them allow the UE to provide location information, however, Nit: "...information; however..." --------------------------------------------------------------------------- §3: >   The "loc-src" parameter adds the location source generating the >   locationValue to increase the trustworthiness of the location >   information. Given that this mechanism doesn't add any authentication mechanisms, I expect that this assertion will raise some eyebrows with the security folks. From a security perspective, the information appears to be exactly as trustworthy as it is without this mechanism. I recommend that this sentence be struck, or changed to something more along the lines of: "...to allow recipients to make informed decisions about which of multiple values to use." --------------------------------------------------------------------------- §7: >   As already stated in [RFC6442] securing the location hop- by-hop, Nit: "stated in [RFC6442], securing..."

Please send substantive comments to the last-call@ietf.org mailing lists by 2020-01-27. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract There are some circumstances where a Geolocation header field may contain more than one locationValue. Knowing the identity of the node adding the locationValue allows the recipient more freedom in selecting the value to look at first rather than relying solely on the order of the locationValues. This document defines the "loc-src" parameter so that the entity adding the locationValue to Geolocation header field can identify itself using its hostname. This document updates RFC 6442. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-sipcore-locparam/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-sipcore-locparam/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references. See RFC 3967 for additional information: rfc3325: Private Extensions to the Session Initiation Protocol (SIP) for Asserted Identity within Trusted Networks (Informational - IETF stream) From nobody

This isn't strictly an issue for this draft, but because this draft introduces a new authentication scheme along side digest it has the potential to aggravate thee issues. ISTM that without answers to these issues it will be difficult to deploy this new token authnz draft. But that draft may not be the appropriate place to answer them. I'd like to hear what others here think is the proper way to deal with this. My general issue is what to do when, while trying to send a request, a UAC receives authorization challenges for multiple schemes and/or multiple realms. This can potentially occur in a single 401 response, a single 407 response, or some combination of 407 and 401 responses. Note that a forking proxy may aggregate 401 and 407 responses from multiple forks and pass the multiple WWW-Authenticate and Proxy-Authenticate responses back to the UAC. How the UAC deals with this is also at issue. Also, if there are multiple authenticating proxies on an unforked path from UAC to UAS, then the UAC will receive the challenges one at a time. The request will only reach a subsequent proxy after the request is sent with adequate credentials for every early proxy in the change. Note that this means that the UAC must remember to include the credentials from earlier challenges when retrying after a subsequent challenge because that subsequent challenge won't include the earlier challenges. (1) is it valid for a single UAS or proxy to issue concurrent challenges specifying differing schemes? I believe it is or should be. (2) is it valid for a single UAS or proxy to issue concurrent challenges on its own behalf specifying differing realms? I'm not sure if this makes sense or not. (This is distinct from a forking proxy aggregating downstream challenges.) (3) If a UAS or proxy does issue concurrent challenges specifying differing schemes, how is the UAC expected to successfully respond? Is the UAC expected to respond with credentials for *each* scheme, or is it sufficient to respond to one of them? I am inclined to think that the different schemes should be considered alternatives, so that it is sufficient to respond to one of them. At least in the case where they are for the same realm. It may be more confusing if they are for differing realms. (4) If multiple UASs and/or proxies claim the same realm then are they expected to accept the same credentials? I think this must be so, else the user and UAC won't be able to sort out what credential to use for a given challenge. Generally, ISTM that the UAC should group challenges by realm, attempting to obtain a single set of credentials for each realm. If there is more than one realm mentioned in the response, then it should obtain a set of credentials for each. And then, if there 407 responses to prior attempts to send this same request then the credentials chosen for them should also be included in this retry. What do others think about this? Do you think this is sufficiently specified in existing RFCs? If so, can you explain this?

List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 20 Jan 2020 17:19:26 -0000 Reviewer: Rich Salz Review result: Has Nits This is the security directorate (secdir) review for the sipcore-locparam draft. Secdir tries to review all documents. The primary intended recipient of this review if the security AD's; all others should consider this to be like any other last-call review. Summary: ready with nits. End of Sec 1 has a quote-based typo. In Sec 3, "This document does not comment..." paragraph is a beautiful acceptance of reality. In Sec 6, do proxies normally add themselves to the Record-Route field? If so, that might be worth mentioning explicitly. In Sec 7, looks good. A couple of typo's "multiple*S* locations" and "hop-by-hop" and "another domain."

Document: draft-ietf-sipcore-locparam-04 Reviewer: Ines Robles Review Date: 2020-01-26 IETF LC End Date: 2020-01-27 IESG Telechat date: Not scheduled for a telechat Summary: This document proposes for SIP protocol, a new geolocation parameter, the location-source ("loc-src"), so that an entity adding the locationValue to Geolocation header field can identify itself using its hostname. The document does not present major issues. I have some minor questions/suggestions at the end. Major issues: Not found Minor issues: Not found Nits/editorial comments: Section 4: "A UA MUST..." it would be nice to expand UA "A User Agent (UA) MUST..." Questions/Suggestions: 1- Section 1: I think it would be nice to add explicitly "This document updates 6442 by extending the Geolocation header field..." 2- Section 3: where it states "There are various architectures defined f...Each has it own characteristics with corresponding pros and cons...." I think it would be nice to add a reference/s to it. 3- Which Geolocation-Error codes correspond to the situation when the "loc-scr" field presents some error, or one LocationValue presents two "loc-src" fields and the locationValue in both cases is correct? Thank you for this document, Ines.

This draft is a work item of the Session Initiation Protocol Core WG of the IETF. Title : Location Source Parameter for the SIP Geolocation Header Field Authors : James Winterbottom Roland Jesske Bruno Chatras Andrew Hutton Filename : draft-ietf-sipcore-locparam-05.txt Pages : 8 Date : 2020-01-28 Abstract: There are some circumstances where a Geolocation header field may contain more than one locationValue. Knowing the identity of the node adding the locationValue allows the recipient more freedom in selecting the value to look at first rather than relying solely on the order of the locationValues. This document defines the "loc-src" parameter so that the entity adding the locationValue to Geolocation header field can identify itself using its hostname. This document updates RFC 6442. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-sipcore-locparam/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-sipcore-locparam-05 https://datatracker.ietf.org/doc/html/draft-ietf-sipcore-locparam-05 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-sipcore-locparam-05 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

Hi Ines,
Thank you for your review.
I have incoperated your comments within the draft.

On Question 1 In Section 1 I have changed the last paragraph by adding the = reference of RF64412 as follows:
=C2=A0" This document extends the Geolocation header field of RFC6442,= by allowing an entity adding the locationValue to identity itself using a = hostname. This is done by defining a new geoloc-param header field paramete= r,

Hope this is OK for you.

Question 2: It is difficult to reference the various architectures for emer= gency since each country, based on national regulation rules, may have it&#= 39;s own architecture.

Question 3: This apply to the rules defined in RFC6442 in Section 4.4.

Best Regards

Roland

Summary:

This document proposes for SIP protocol, a new geolocation parameter, the l= ocation-source ("loc-src"), so that an entity adding the location= Value to Geolocation header field can identify itself using its hostname.
The document does not present major issues. I have some minor questions/sug= gestions at the end.

Major issues: Not found

Minor issues: Not found

Nits/editorial comments:

Section 4: "A UA MUST..." it would be nice to expand UA "A U= ser Agent (UA) MUST..."

Questions/Suggestions:

1- Section 1: I think it would be nice to add explicitly "This documen= t updates
6442 by extending the Geolocation header field..."

2- Section 3:=C2=A0 where it states "There are various architectures d= efined f...Each has it own characteristics with corresponding pros and cons= ...." I think it would be nice to add a reference/s to it.

3- Which Geolocation-Error codes correspond to the situation when the "= ;loc-scr"
field presents some error, or one LocationValue presents two "loc-src&= quot; fields and the locationValue in both cases is correct?

Thank you for this document,

Ines.

The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-sipcore-locparam/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Thanks for this easy-to-read document! I do have a few comments, including places where we could improve the internal consistency of our recommendations and requirements. Section 3 The primary intent of the "loc-src" parameter in this specification is for use in emergency calling. There are various architectures defined for providing emergency calling using SIP-based messaging. It's a little interesting to see this listed as the "primary intent" to the implied exclusion of the other uses of location envisoned by RFC 6442. Would those other uses for location information not also be interested in the origin of a given piece of location information? The "loc-src" parameter is not included in a SIP message sent to another network if there is no trust relationship. The "loc-src" parameter is not applicable if the administrative domain manages emergency calls in a way that does not require any generation of the location. This statement seems to provide stronger constraints (e.g., be in conflict with) the previous quote about "primary intent", and corresponds more to "sole intent" than "primary intent". The functional architecture described within ETSI [M493] is an example of an architecture where it makes sense to use this parameter. nit: I expect that there are many architectures specified by ETSI, so additional qualifiers (e.g., "telephony" or "emergency telephony") might be appropriate. Section 6 This document doesn't change any of the privacy considerations described in [RFC6442]. While the addition of the "loc-src" parameter identifies the entity that added the location in the signaling path, this addition provides little more exposure than adding a proxy identity to the Record-Route header field. Are the privacy considerations of adding a proxy identity to the Record-Route header field documented somewhere we could reference? Section 7 This document introduces the ability of a SIP intermediary to insert a host name indicating that they added the specific locationValue to the Geolocation header field. The intent is for this field to be used by the location recipient in the event that the SIP message contains multiple locationValues. As a consequence this parameter should only be used by the location recipient in a trusted network. I see that essentially the same sentiment is already included in the following paragraph, but I might consider noting here that "adding this parameter in an untrusted network serves solely to give location information to untrusted parties, and is disrecommended" out of some sense of parallelism. But that' purely stylistic, so do what sounds best to you! As already stated in [RFC6442], securing the location hop-by-hop, using TLS, protects the message from eavesdropping and modification in transit, but exposes the information to all SIP intermediaries on Hmm, though RFC 6442 does not seem to require use of TLS (or equivalent). It would be reasonable to include a brief discussion of the risks incurred by not using TLS, though I don't insist on it. the path as well as the endpoint. The "loc-src" parameter is applicable within a single private administrative domain or between different administrative domains where there is a trust relationship between the domains. If such trust domain is not given, it is strongly recommended to delete the location information. nit: I'm not sure if "If such trust domain is not given" parses properly; is there a missing word or two? multiple locations. To avoid problems with misinterpretation of the "loc-src" parameter, the value may be removed when passed to another domain. I think we already made a suggestion stronger than "may" to do so.
