1. Overview
This document is informational, and is *not normative* on any aspect
of SIP.
This document contains test messages based on the current version
(2.0) of the Session Initiation Protocol as defined in [RFC 3261].
This document is expected to be used as a companion document to the
more general SIP torture test document [RFC 4475], which does not
include specific tests for IPv6 network identifiers.
This document does not attempt to catalog every way to make an
invalid message, nor does it attempt to be comprehensive in exploring
unusual, but valid, messages. Instead, it tries to focus on areas
that may cause interoperability problems in IPv6 deployments.
2. Document Conventions
This document contains many examples of SIP messages with IPv6
network identifiers. The appendix contains an encoded binary form
containing the bit-exact representation of all the messages and the
script needed to decode them into separate files.
Gurbani, et al. Informational PAGE 2
RFC 5118 SIP IPv6 Torture Tests February 2008
The IPv6 addresses used in this document correspond to the 2001:
DB8::/32 address prefix reserved for documentation [RFC 3489].
Likewise, the IPv4 addresses used in this document correspond to the
192.0.2.0/24 address block as described in [RFC 3330].
Although SIP is a text-based protocol, some of these examples cannot
be unambiguously rendered without additional markup due to the
constraints placed on the formatting of RFCs. This document uses the
<allOneLine/> markup convention established in [RFC 4475] to avoid
ambiguity and meet the Internet-Draft layout requirements. For the
sake of completeness, the text defining this markup from Section 2.1
of [RFC 4475] is reproduced in its entirety below:
Several of these examples contain unfolded lines longer than 72
characters. These are captured between <allOneLine/> tags. The
single unfolded line is reconstructed by directly concatenating
all lines appearing between the tags (discarding any line feeds or
carriage returns). There will be no whitespace at the end of
lines. Any whitespace appearing at a fold-point will appear at
the beginning of a line.
The following represent the same string of bits:
Header-name: first value, reallylongsecondvalue, third value
<allOneLine>
Header-name: first value,
reallylongsecondvalue
, third value
</allOneLine>
<allOneLine>
Header-name: first value,
reallylong
second
value,
third value
</allOneLine>
Note that this is NOT SIP header-line folding, where different
strings of bits have equivalent meaning.

3. SIP and IPv6 Network Configuration
System-level issues like deploying a dual-stack proxy server,
populating DNS with A and AAAA Resource Records (RRs), zero-
configuration discovery of outbound proxies for IPv4 and IPv6
networks, when a dual-stack proxy should Record-Route itself, and
media issues also play a major part in the transition to IPv6. This
document does not, however, address these issues. Instead, a
companion document [sip-trans] provides more guidance on these
issues.
4. Parser Torture Tests
The test messages are organized into several sections. Some stress
only the SIP parser and others stress both the parser and the
application above it. Some messages are valid and some are not.
Each example clearly calls out what makes any invalid messages
incorrect.
Please refer to the complete Augmented Backus-Naur Form (ABNF) in
[RFC 3261] on representing IPv6 references in SIP messages. IPv6
references are delimited by a "[" and "]". When an IPv6 reference is
part of a SIP Uniform Resource Identifier (URI), RFC 3261 mandates
that the "IPv6reference" production rule be used to recognize tokens
that comprise an IPv6 reference. More specifically, the ABNF states
the following:
SIP-URI = "sip:" [ userinfo ] hostport
uri-parameters [ headers ]
hostport = host [ ":" port ]
host = hostname / IPv4address / IPv6reference
IPv4address = 1*3DIGIT "." 1*3DIGIT "." 1*3DIGIT "." 1*3DIGIT
IPv6reference = "[" IPv6address "]"
IPv6address = hexpart [ ":" IPv4address ]
hexpart = hexseq / hexseq "::" [ hexseq ] / "::" [ hexseq ]
hexseq = hex4 *( ":" hex4)
hex4 = 1*4HEXDIG

4.1. Valid SIP Message with an IPv6 Reference
The request below is well-formatted according to the grammar in
[RFC 3261]. An IPv6 reference appears in the Request-URI (R-URI), Via
header field, and Contact header field.
Message Details: ipv6-good
REGISTER sip:[2001:db8::10] SIP/2.0
To: sip:user@example.com
From: sip:user@example.com;tag=81x2
Via: SIP/2.0/UDP [2001:db8::9:1];branch=z9hG4bKas3-111

Max-Forwards: 70
Contact: "Caller" <sip:caller@[2001:db8::1]>
CSeq: 98176 REGISTER
Content-Length: 0
4.2. Invalid SIP Message with an IPv6 Reference
The request below is not well-formatted according to the grammar in
[RFC 3261]. The IPv6 reference in the R-URI does not contain the
mandated delimiters for an IPv6 reference ("[" and "]").
A SIP implementation receiving this request should respond with a 400
Bad Request error.
Message Details: ipv6-bad

4.3. Port Ambiguous in a SIP URI
IPv6 uses the colon to delimit octets. This may lead to ambiguity if
the port number on which to contact a SIP server is inadvertently
conflated with the IPv6 reference. Consider the REGISTER request
below. The sender of the request intended to specify a port number
(5070) to contact a server, but inadvertently, inserted the port
number inside the closing "]" of the IPv6 reference. Unfortunately,
since the IPv6 address in the R-URI is compressed, the intended port
number becomes the last octet of the reference.
From a parsing perspective, the request below is well-formed.
However, from a semantic point of view, it will not yield the desired
result. Implementations must ensure that when a raw IPv6 address
appears in a SIP URI, then a port number, if required, appears
outside the closing "]" delimiting the IPv6 reference. Raw IPv6
addresses can occur in many header fields, including the Contact,
Route, and Record-Route header fields. They also can appear as the
result of the "sent-by" production rule of the Via header field.
Implementers are urged to consult the ABNF in [RFC 3261] for a
complete list of fields where a SIP URI can appear.

4.4. Port Unambiguous in a SIP URI
In contrast to the example in Section 4.3, the following REGISTER
request leaves no ambiguity whatsoever on where the IPv6 address ends
and the port number begins. This REGISTER request is well formatted
per the grammar in [RFC 3261].
Message Details: port-unambiguous

4.5. IPv6 Reference Delimiters in Via Header
IPv6 references can also appear in Via header fields; more
specifically in the "sent-by" production rule and the "via-received"
production rule. In the "sent-by" production rule, the sequence of
octets comprising the IPv6 address is defined to appear as an
"IPv6reference" non-terminal, thereby mandating the "[" and "]"
delimiters. However, this is not the case for the "via-received"
non-terminal. The "via-received" production rule is defined as
follows:
via-received = "received" EQUAL (IPv4address / IPv6address)
The "IPv6address" non-terminal is defined not to include the
delimiting "[" and "]". This has led to the situation documented
during the 18th SIP Interoperability Event [Email-SIPit]:
Those testing IPv6 made different assumptions about enclosing
literal v6 addresses in Vias in []. By the end of the event, most
implementations were accepting either. Its about 50/50 on what
gets sent.
While it would be beneficial if the same non-terminal
("IPv6reference") was used for both the "sent-by" and "via-received"
production rules, there has not been a consensus in the working group
to that effect. Thus, the best that can be suggested is that
implementations must follow the Robustness Principle [RFC 1122] and be
liberal in accepting a "received" parameter with or without the
Gurbani, et al. Informational PAGE 7
RFC 5118 SIP IPv6 Torture Tests February 2008
delimiting "[" and "]" tokens. When sending a request,
implementations must not put the delimiting "[" and "]" tokens.
The two test cases below are designed to stress this behavior. A SIP
implementation receiving either of these messages must parse them
successfully.
The request below contains an IPv6 address in the Via "received"
parameter. The IPv6 address is delimited by "[" and "]". Even
though this is not a valid request based on a strict interpretation
of the grammar in [RFC 3261], robust implementations must nonetheless
be able to parse the topmost Via header field and continue processing
the request.

4.9. IPv4-Mapped IPv6 Addresses
An IPv4-mapped IPv6 address is usually represented with the last 32
bits appearing as a dotted-decimal IPv4 address; e.g., ::ffff:
192.0.2.1. A SIP implementation receiving a message that contains
such a mapped address must be prepared to parse it successfully. An
IPv4-mapped IPv6 address may appear in signaling, or in the SDP
carried by the signaling message, or in both. If a port number is
part of the URI represented by the IPv4-mapped IPv6 address, then it
must appear outside the delimiting "]" (cf. Section 4.4).
The message below is well-formed according to the grammar in
[RFC 3261]. The Via list contains two Via headers, both of which
include an IPv4-mapped IPv6 address. An IPv4-mapped IPv6 address
also appears in the Contact header and the SDP. The topmost Via
header includes a port number that is appropriately delimited by "]".

4.10. IPv6 Reference Bug in RFC 3261 ABNF
It is possible to follow the IPv6reference production rule of RFC
3261 ABNF -- the relevant portion of which is reproduced at the top
of Section 4 -- and arrive at the following construct:
[2001:db8:::192.0.2.1]
Gurbani, et al. Informational PAGE 11
RFC 5118 SIP IPv6 Torture Tests February 2008
Note the extra colon before the IPv4 address in the above construct.
The correct construct, of course, is:
[2001:db8::192.0.2.1]
The ABNF pertaining to IPv6 references in RFC 3261 was derived from
RFC 2373 [RFC 2373], which has been obsoleted by RFC 4291 [RFC 4291].
The specific behavior of inserting an extra colon was inherited from
RFC 2373, and has been remedied in RFC 4291. However, following the
Robustness Principle [RFC 1122], an implementation must tolerate both
of the above constructs.
The message below includes an extra colon in the IPv6 reference. A
SIP implementation receiving such a message may exhibit robustness by
successfully parsing the IPv6 reference (it can choose to ignore the
extra colon when parsing the IPv6 reference. If the SIP
implementation is acting in the role of a proxy, it may additionally
serialize the message without the extra colon to aid the next
downstream server).

5. Security Considerations
This document presents examples of SIP messages with IPv6 references
contained in the signaling headers and SDP payload. While this
document may clarify the behavior of SIP elements processing a
message with IPv6 references, it does not normatively change the base
SIP [RFC 3261] specification in any way. Consequently, all security
considerations in [RFC 3261] apply.
Parsers must carefully consider edge conditions and malicious input
as part of their design. Attacks on many Internet systems use
crafted input to cause implementations to behave in undesirable ways.
Many of the messages in this document are designed to stress a parser
implementation at points traditionally used for such attacks. This
document does not, however, attempt to be comprehensive. It contains
some common pitfalls that the authors have discovered while parsing
IPv6 identifiers in SIP implementations.

Appendix A. Bit-Exact Archive of Each Test Message
The following text block is an encoded, gzip compressed TAR archive
of files that represent each of the example messages discussed in
Section 4.
To recover the compressed archive file intact, the text of this
document may be passed as input to the following Perl script (the
output should be redirected to a file or piped to "tar -xzvf -").
#!/usr/bin/perl
use strict;
my $bdata = "";
use MIME::Base64;
while(<>) {
if (/-- BEGIN MESSAGE ARCHIVE --/ .. /-- END MESSAGE ARCHIVE --/) {
if ( m/^\s*[^\s]+\s*$/) {
$bdata = $bdata . $_;
}
}
}
