git:master: modules_k/registrar: New outbound_mode parameter

[tracker] Task opened: decode_contact() fails on certain legitimate request URIs

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Richard Brady (rnbrady) Attached to Project - sip-router Summary - decode_contact() fails on certain legitimate request URIs Task Type - Bug Report Category - Modules kamailio Status - Unconfirmed Assigned To - Operating System - Linux Severity - Low Priority - Normal Reported Version - 3.3 Due in Version - Undecided Due Date - Undecided Details - Decode contact() fails decode_contact() fails on certain legitimate request URIs, such as: sip:natted_ua*alice;day=tuesday**192.168.242.102*5060*udp@1.2.3.4 This is due to the semicolon in the userinfo part of the URI. The problem code is in the decode2format function in siputils/contact_ops.c: if (((*pos) == '>')||(*pos == ';')) { /* invalid chars inside username part */ return -5; } The ABNF in RFC3261 makes it clear that a semicolon is ok in the user-info field: userinfo = ( user / telephone-subscriber ) [ ":" password ] "@" user = 1*( unreserved / escaped / user-unreserved ) user-unreserved = "&" / "=" / "+" / "$" / "," / ";" / "?" / "/" The code might be to check for the end of a URI (both those characters terminate a URI under certain circumstances), perhaps for fault tolerance and/or security but I don't think it's been done in a way that makes sense, for the following reasons: 1. An angle bracket is not legal in or surrounding a request URI, so it should be picked up by the parser and/or sanity check. 2. A semicolon is totally legal in the userinfo part, as per ABNF above and also as explained in RFC3261: ... sip:alice;day=tuesday@atlanta.com The last sample URI above has a user field value of "alice;day=tuesday". The escaping rules defined above allow a semicolon to appear unescaped in this field. For the purposes of this protocol, the field is opaque. The structure of that value is only useful to the SIP element responsible for the resource.

Outbound Edge Proxy support now in git master

by Peter Dunkley

Hello, I have merged the Edge Proxy support into git master. I'd appreciate it if anyone who has a client that supports outbound (and a registrar that supports it) as I have been travelling the last couple of weeks while I've been working on this and have had access to neither. I thought it would also be worth summarising what I know is still required for full outbound support on Kamailio. I hope to have time to do some of this (items 1 and 2 specifically) during the week, but it will be my first week back in the office and I am travelling again the week after. If I have time I will do some of these - but if there is anyone else who sees these as particularly important and wants to pick them up I'd be grateful: 1) registrar module support for RFC 5626 section 6: When receiving a REGISTER request, the registrar MUST check from its Via header field if the registrar is the first hop or not. If the registrar is not the first hop, it MUST examine the Path header of the request. If the Path header field is missing or it exists but the first URI does not have an "ob" URI parameter, then outbound processing MUST NOT be applied to the registration. In this case, the following processing applies: if the REGISTER request contains the reg-id and the outbound option tag in a Supported header field, then the registrar MUST respond to the REGISTER request with a 439 (First Hop Lacks Outbound Support) response; otherwise, the registrar MUST ignore the "reg-id" parameter of the Contact header. 2) registrar modparam that specifies whether outbound is supported, required, or neither. Behaviour when neither: * As now Behaviour when supported: * Add Supported: header with outbound options-tag to the 200 OK Behaviour when required: * Reject (with 421 Extension Required) REGISTER requests without the outbound options-tag in a Supported: or Require: header * Add Supported: and Require: headers with outbound options-tag to the 200 OK 3) Single server (combined edge proxy and registrar) behaviour 4) Testing along side registrar and usrloc module changes for multiple registrations from a single UA. Note: There shouldn't be any conflict here as the edge and registrar changes should be independent of each other. However, I have no idea how to configure and use the new registrar and usrloc features. -- Peter Dunkley Technical Director Crocodile RCS Ltd
