Most issues were in stringfields and had to do with comparing
a pointer to an constant/interned string with NULL. Since the
string was a constant, a pointer to it could never be NULL so
the comparison was always "true". gcc now complains about that.
There were also a few issues where determining if there was
enough space for a memcpy or s(n)printf which were fixed
by defining some of the involved variables as "volatile".
There were also a few other miscellaneous fixes.

Enhancements:
* The MessageSend dialplan application now takes an optional
third argument that can set the message's "To" field on
outgoing messages. It's an alternative to using the
MESSAGE(to) dialplan function.
NOTE: No channel driver currently implements this field. A
follow-on commit for res_pjsip_messaging will implement it for
the chan_pjsip channel driver.
* To prevent confusion with the first argument, currently named
"to", it's been renamed to "destination". Its function,
creating the request URI, hasn't changed.
* The documentation for MessageSend was updated to be
more clear about the parameters and how they interact
the MESSAGE() dialplan function.
* With the rename of MessageSend's first parameter, and the fact
that message.c references <info> elements in chan_sip.c,
res_pjsip_messaging.c and res_xmpp, they each needed
documentation updates to use MessageDestinationInfo instead of
MessageToInfo.
* appdocsxml.dtd was updated to include a missing element
declaration for "dataType". This was showing up as an error
in Eclipse's dtd editor.
* Despite the changes in this commit, there should be
no impact to current users of MessageSend.

Instead of looking for pass-through formats in the list of transcodable

is going to be the jointcaps of the tech_pvt of the channel. Finally,
only with that list, ast_format_cap_remove(.) is going to succeed.
This restores the behaviour of Asterisk 1.8. However, it does not fix

Two previous commits, 620d9f4 and 6d980de, allow to set up a call
without audio, again. That was introduced originally with commit f04d5fb
but changed and broke over time. The original commit missed one
scenario: A [peer] section in sip.conf, which does not allow audio at
all. In that case, chan_sip rejected the call, although even when the
requester offered no audio. Now, chan_sip does not check whether there
is no audio format but checks whether there is no format in general. In
other words, if there is at least one format to offer, the call succeeds.
However, to prevent calls with no-audio, chan_sip still rejects calls
when both call parties (caller = requester of the call *and* callee =
[peer] section in sip.conf) included audio. In such a case, it is
expected that the call should have audio.

The previous commit 6d980de fixed this issue in the core of Asterisk.
With that, each channel technology can be used without audio
theoretically. Practically, the channel-technology driver chan_sip
turned out to have an invalid check preventing that. chan_sip tested
whether there is at least one audio format. However, chan_sip has to
test whether there is at least one format. More cannot be tested while
requesting chan_sip because only the [general] capabilities but not the
[peer] caps are known yet. And the [peer] caps might not be a subset or
show any intersection with the [general] caps. This change here fixes
this.
The original commit f04d5fb, thirteen years ago, contained a software
bug as it passed ANY audio capability to the channel-technology driver.
Instead, it should have passed NO audio format. Therefore, this
addressed issue here was not noticed in Asterisk 1.6.x and Asterisk 1.8.
Then, Asterisk 10 changed that from ANY to NO, but nobody reported since
then.

This completes the fix for ASTERISK_24543. Only when the call is an
outgoing call, consult and append the configured format capabilities
(p->caps). When all audio formats got rejected the negotiated format
capabilities (p->jointcaps) contain no audio formats for incoming
calls. This is required when there are other accepted media streams.

Previously, chan_sip parsed all known media streams in an SDP offer
like video (and text) even when videosupport=no (and textsupport=no).
This wasted processor power. Furthermore, chan_sip accepted SDP offers,
including no audio but just video (or text) streams although
videosupport=no (or textsupport=no). Finally, chan_sip denied the whole
offer instead of individual streams when they had encryption (SDES-sRTP)
unexpectedly enabled.

RFC 8760 added new digest-access-authentication schemes. Testing
revealed that chan_sip does not pick MD5 if several schemes are offered
by the User Agent Server (UAS). This change does not implement any of
the new schemes like SHA-256. This change makes sure, MD5 is picked so
UAS with SHA-2 enabled, like the service www.linphone.org/freesip, can
still be used. This should have worked since day one because SIP/2.0
already envisioned several schemes (see RFC 3261 and its augmented BNF
for 'algorithm' which includes 'token' as third alternative; note: if
'algorithm' was not present, MD5 is still assumed even in RFC 7616).

chan_sip handle_response() function, for a 400 response to an INVITE,
calls handle_response_invite() and does not generate ACK.
handle_response_invite() does not recognize 400 response and has no
default response processing for unexpected responses, thus it does not
generate ACK either.
The ACK on response repetition comes from handle_response() mechanism
"We must re-send ACKs to re-transmitted final responses".
According to code history, 400 response specific processing was
introduced with commit
"channels/chan_sip: Add improved support for 4xx error codes"
This commit added support for :
- 400/414/493 in handle_response_subscribe() handle_response_register()
and handle_response().
- 414/493 only in handle_response_invite().
This fix adds 400 response support in handle_response_invite().

Fixes no-audio issues when the media source is changed and
strictrtp is enabled (default).
If the peer media source changes, the SDP session version also changes.
If it is lower than the one we had stored, chan_sip would ignore it.
This changeset keeps track of the remote media origin identifier,
comparing that as well. If it changes, the session version needn't be
higher for us to accept the SDP.
Common scenario where this would've caused problems: a separate media
gateway that informs the caller about premium rates before handing off
the call to the final destination.
(An alternative fix would be to set ignoresdpversion=yes on the peer.)

peer's name, the address of the peer will change even if the request

Also remove function peer_ipcmp_cb since it's not used (according to
rmudgett).
Prior to b2c4e8660a (ASTERISK_27457)
insecure=port was the defacto standard. That commit also prevented
insecure=port from being applied for sip/tcp or sip/tls.
Into consideration there are three sets of behaviour:
1. "previous" - before the above commit.
2. "current" - post above commit, pre this one.
3. "new" - post this commit.
The problem that the above commit tried to address was guests over TCP.
It succeeded in doing that but broke transport!=udp with host!=dynamic.
This commit attempts to restore sane behaviour with respect to
transport!=udp for host!=dynamic whilst still retaining the guest users
over tcp.
It should be noted that when looking for a peer, two passes are made, the
first pass doesn't have SIP_INSECURE_PORT set for the searched-for peer,
thus looking for full matches (IP + Port), the second pass sets
SIP_INSECURE_PORT, thus expecting matches on IP only where the matched
peer allows for that (in the author's opinion: UDP with insecure=port,
or any TCP based, non-dynamic host).
In previous behaviour there was special handling for transport=tcp|tls
whereby a peer would match during the first pass if the utilized
transport was TCP|TLS (and the peer allowed that specific transport).
This behaviour was wrong, or dubious at best. Consider two dynamic tcp
peers, both registering from the same IP (NAT), in this case either peer
could match for connections from an IP. It's also this behaviour that
prevented SIP guests over tcp.
The above referenced commit removed this behaviour, but kept applying
the SIP_INSECURE_PORT only to WS|WSS|UDP. Since WS and WSS is also TCP
based, the logic here should fall into the TCP category.
This patch updates things such that the previously non-explicit (TCP
behaviour) transport test gets performed explicitly (ie, matched peer
must allow for the used transport), as well as the indeterministic
source-port nature of the TCP protocol is taken into account. The new
match algorithm now looks like:
1. As per previous behaviour, IP address is matched first.
2. Explicit filter with respect to transport protocol, previous
behaviour was semi-implied in the test for TCP pure IP match - this now
made explicit.
3. During first pass (without SIP_INSECURE_PORT), always match on port.
4. If doing UDP, match if matched against peer also has
SIP_INSECURE_PORT, else don't match.
5. Match if not a dynamic host (for non-UDP protocols)
6. Don't match if this is WS|WSS, or we can't trust the Contact address
(presumably due to NAT)
7. Match (we have a valid Contact thus if the IP matches we have no
choice, this will likely only apply to non-NAT).
To logic-test this we need a few different scenarios. Towards this end,
I work with a set number of peers defined in sip.conf:
[peer1]
host=1.1.1.1
transport=tcp
[peer2]
host=1.1.1.1
transport=udp
[peer3]
host=1.1.1.1
port=5061
insecure=port
transport=udp
[peer4]
host=1.1.1.2
transport=udp,tcp
[peer5]
host=dynamic
transport=udp,tcp
Test cases for UDP:
1 - incoming UDP request from 1.1.1.1:
- previous:
- pass 1:
* peer1 or peer2 if from port 5060 (indeterminate, depends on peer
ordering)
* peer3 if from port 5061
* peer5 if registered from 1.1.1.1 and source port matches
- pass 2:
* peer3
- current: as per previous.
- new:
- pass 1:
* peer2 if from port 5060
* peer3 if from port 5061
* peer5 if registered from 1.1.1.1 and source port matches
- pass 2:
* peer3
2 - incoming UDP request from 1.1.1.2:
- previous:
- pass 1:
* peer5 if registered from 1.1.1.2 and port matches
* peer4 if source port is 5060
- pass 2:
* no match (guest)
- current: as previous.
- new as previous (with the variation that if peer5 didn't have udp as
allowed transport it would not match peer5 whereas previous
and current code could).
3 - incoming UDP request from anywhere else:
- previous:
- pass 1:
* peer5 if registered from that address and source port matches.
- pass 2:
* peer5 if insecure=port is additionally set.
* no match (guest)
- current - as per previous
- new - as per previous
Test cases for TCP based transports:
4 - incoming TCP request from 1.1.1.1
- previous:
- pass 1 (indeterministic, depends on ordering of peers in memory):
* peer1; or
* peer5 if peer5 registered from 1.1.1.1 (irrespective of source port); or
* peer2 if the source port happens to be 5060; or
* peer3 if the source port happens to be 5061.
- pass 2: cannot happen since pass 1 will always find a peer.
- current:
- pass 1:
* peer1 or peer2 if from source port 5060
* peer3 if from source port 5060
* peer5 if registered as 1.1.1.1 and source port matches
- pass 2:
* no match (guest)
- new:
- pass 1:
* peer 1 if from port 5060
* peer 5 if registered and source port matches
- pass 2:
* peer 1
5 - incoming TCP request from 1.1.1.2
- previous (indeterminate, depends on ordering):
- pass 1:
* peer4; or
* peer5 if peer5 registered from 1.1.1.2
- pass 2: cannot happen since pass 1 will always find a peer.
- current:
- pass 1:
* peer4 if source port is 5060
* peer5 if peer5 registered as 1.1.1.2 and source port matches
- pass 2:
* no match (guest).
- new:
- pass 1:
* peer4 if source port is 5060
* peer5 if peer5 registered as 1.1.1.2 and source port matches
- pass 2:
* peer4
6 - incoming TCP request from anywhere else:
- previous:
- pass 1:
* peer5 if registered from that address
- pass 2: cannot happen since pass 1 will always find a peer.
- current:
- pass 1:
* peer5 if registered from that address and port matches.
- pass 2:
* no match (guest)
- new: as per current.
It should be noted the test cases don't make explicit mention of TLS, WS
or WSS. WS and WSS previously followed UDP semantics, they will now
enforce source port matching. TLS follow TCP semantics.
The previous commit specifically tried to address test-case 6, but broke
test-cases 4 and 5 in the process.
