[OpenSER-Users] Problems with SIMPLE-XMPP presence

Well, I have made some tests and I think I have found what could be a wrong
behaviour of the pua_xmpp module, leading to the situation described in the
previous post. I will try to explain it better here.
Every time a XMPP client changes its presence status, pua_xmpp sends what
seems to be re-subscribes for each of its contacts belonging to the SIP
domain. The problem is that they are not linked with the original suscribes
because they don't have the same To-Tag (neither have they the same branch
in Via header, but I don't think that's important). For example:
- PREVIOUS SUBSCRIBE:
SUBSCRIBE sip:354 at openser.domain SIP/2.0
Via: SIP/2.0/UDP 10.95.43.31;branch=z9hG4bKe5a9.a616d022.0
To: sip:354 at openser.domain
From:
sip:pge354*xmpp.domain at xmpp-gw;tag=533cb9e91f4b999cf76861cbb9ed54ed-be94
CSeq: 10 SUBSCRIBE
Call-ID: 7d71efef-20757 at 10.95.43.31
Content-Length: 0
User-Agent: OpenSER (1.3.1-notls (i386/linux))
Max-Forwards: 70
Event: presence
Contact: <sip:pge354*xmpp.domain at xmpp-gw>
Expires: 473
- NEW SUBSCRIBE AFTER STATUS CHANGE:
SUBSCRIBE sip:354 at openser.domain SIP/2.0
Via: SIP/2.0/UDP 10.95.43.31;branch=z9hG4bKf5a9.e1802f23.0
To: sip:354 at openser.domain;tag=10.20757.1209988007.20
From:
sip:pge354*xmpp.domain at xmpp-gw;tag=533cb9e91f4b999cf76861cbb9ed54ed-be94
CSeq: 11 SUBSCRIBE
Call-ID: 7d71efef-20757 at 10.95.43.31
Content-Length: 0
User-Agent: OpenSER (1.3.1-notls (i386/linux))
Max-Forwards: 70
Event: presence
Contact: <sip:pge354*xmpp.domain at xmpp-gw>
Expires: 3610
As a result, the later subscribe request is rejected with a 404 Not Here
response. The pua_xmpp, upon receiving the response, sends a brand new
subscribe request, that has nothing to do with the others and is accepted by
openser.
When this is done for every contact the XMPP client has, I can see in
database how presentity table has one more row that it had before (showing
the last status change) and how active_watchers table has grown as many rows
as contacts have been involved (one for each new suscribe). And they keep
growing every time there is a change in the presence status of the XMPP
client.
So, please, let me know whether I am right and this is something to be
fixed.
Thank you,
Pablo

Thanks, Anca, that was it :)
Now presence information is shown in both the SIP and the XMPP client, but
there are still some estrange behaviours in openser.
First, when I start the SIP client with the XMPP client already online, some
kind of loop occurs, as you can see in the log attached. The following
NOTIFY message is sent again and again for a while, changing just the
from-tag, branch and call-id:
NOTIFY sip:pge354*xmpp.domain at xmpp-gw SIP/2.0
Via: SIP/2.0/UDP 10.95.43.31;branch=z9hG4bK1d12.1b727435.0
To: sip:pge354*xmpp.domain at xmpp-gw;tag=533cb9e91f4b999cf76861cbb9ed54ed-38b3
From: sip:354354 at openser.domain;tag=10.1700.1208442687.20
CSeq: 2 NOTIFY
Call-ID: 6ce7eb86-1701 at 10.95.43.31
Content-Length: 471
User-Agent: OpenSER (1.3.1-notls (i386/linux))
Max-Forwards: 70
Event: presence
Contact: <sip:10.95.43.31>
Subscription-State: active;expires=2631
Content-Type: application/pidf+xml
<...>
The first couple of them get the following response, but not all the others,
that get no answer:
SIP/2.0 200 OK
Via: SIP/2.0/UDP 10.95.43.31;branch=z9hG4bK1d12.1b727435.0
To: sip:pge354*xmpp.domain at xmpp-gw;tag=533cb9e91f4b999cf76861cbb9ed54ed-38b3
From: sip:354354 at openser.domain;tag=10.1700.1208442687.20

It seems that the responses are not taken into account, or maybe it is
related with the other thing I find weird, the fact that pua and presentity
tables in Mysql database grows continuously with registries that are much
like already existing ones. Sample of the pua table:
| 18432 | sip:pge354*xmpp.domain at xmpp-gw | | 1 | 1208449465 |

Every time the XMPP client changes its presence state, one registry is added
to the presentity table. Sample:
| 783 | pge354*xmpp.domain | xmpp-gw | presence |
a.1208441749.1701.36.1 | 1208449478 | 1208445878 | <?xml version="1.0"?>

xmlns:c="urn:ietf:params:xml:ns:pidf:cipid"
entity="pres:pge354*xmpp.domain at xmpp-gw">
<tuple id="0xbf9787bc">
<status>

</tuple>
</presence>
|
| 785 | pge354*xmpp.domain | xmpp-gw | presence |
a.1208441749.1702.45.0 | 1208449517 | 1208445917 | <?xml version="1.0"?>

<tuple id="0xbf9787bc">

</status>
</tuple>
</presence>
|
| 786 | pge354*xmpp.domain | xmpp-gw | presence |
a.1208441749.1702.52.1 | 1208450140 | 1208446540 | <?xml version="1.0"?>

How can I solve all this issues?

Hello,
There is something missing in your configuration file. See econfig
example from version 1.3 (etc/openser.cfg, line 214). You should add
something like this on the else branch for in dialog requests:
if (is_method("SUBSCRIBE|NOTIFY") && ($rd == "your.server.ip.address"|
$rd=="xmpp-gw"))
{
# in-dialog subscribe requests
route(2);
exit;
}
The way you have it now, all in dialog requests are not allowed, that is
all Notifies and the in dialog Subscribes.
regards,
Anca Vamanu
