dlg relase for dlg_set_timeout_by_profile()

by Daniel-Constantin Mierla

Hello Alex, while analyzing the code of dialog module to allow setting the timeout even before the dialog is answered, I noticed that dlg_set_timeout_by_profile() is using update_dlg_timeout(), the later doing a dlg_release() inside it. However, dlg_set_timeout_by_profile() does another dlg_release() after update_dlg_timeout(), which seems wrong at first sight, resulting in two dereferences of the counter. Looking at git blame, dlg_release in both dlg_set_timeout_by_profile() and update_dlg_timeout() were added (or least last changed) by you. I would move the dlg_release() out of update_dlg_timeout(), because it is rather not intuitive to expect being done there, instead of where the dlg was referenced. Can you analyze and see if that is safe for your dlg_set_timeout_by_profile(), or another dlg_release() should be done inside it (as it gets removed from update_dlg_timeout() )?

Trunk: DMQ and hashtables - won't start and crashes

by Olle E. Johansson

Using trunk code, I can get DMQ to work by itself. I have three test servers that I take up and down and it seems to work. As soon as I enable DMQ in htable, without enabling any replication of any hash table, Kamailio refuse to start. Seems to be a chicken-and-egg issue, maybe loading order? I could not find a solution. Also, without enabling DMQ, if I use dmq_send_message() in htable:init event route Kamailio crashes. This is all on my OS/X system with latest git code. /O

RTPEngine stops working randomly

by Muhammad Shahzad

Hi, Since last couple of weeks we noticed that RTPEngine random stops working for chrome to chrome (i.e. webrtc) calls. After some digging in syslog we found that when problem occurs following error is appears in logs, -- rtpengine[24162]: [ollkcvqi1m9k1n55lh2a port 49936] DTLS error: 1 (tlsv1 alert decrypt error) -- For each call afterwords it gives this exact same error (with different call-id and port of course) and media flow fails. The only workaround we found so far is to restart the rtpengine service. The problem is very random, sometimes it does not happens for days, and sometimes it happens say every couple of hours or so. Kamailio version is stable release 4.2.1-fad00a. RTPEngine version is 3.3.0.0+0~mr3.7.0.0. Operating System is Debian 7.x, 32bit with Linux Kernel version 3.10-0.bpo.2-686-pae. Thank you.

presentity active_watchers and uri parameters

by Jasmin Schnatterbeck

Hi, IMHO there is a bug in the active_watchers storage regarding the To and From uri: According to rfc3261 the from-uri and to-uri have to be identical (but may swapped) for subsequent in-dialog-requests. [1],[2] uri-parameters are part of uris. [3] But uri-parameters are not stored in the active_watchers table when a SUBSCRIBE request is processed - as a result, the uri parameters of subsequent in-dialog NOTIFY-requests generated by presentity are missing. This does not only violate rfc3261, it also has severe consequences - e.g. regarding the uac_replace_from() and uac_replace_to() functions, which are used in a kamailio-node in front of the presentity-node. In order to reconstruct the "old" uris of in-dialog requests, those functions need the correct new uris - otherwise the reconstruction of the old uris is messed up. So I suggest to store to uri and from uri in active_watchers using one column for the whole uri (including uri parameters). Or is there another reason for the current situation (storing userpart and domain separately)? Cheers Jasmin [1] rfc3261 Section 12.1.1 [last sentence] The remote URI MUST be set to the URI in the From field, and the local URI MUST be set to the URI in the To field. [2] rfc3261 Section 12.2.1.1 The From URI of the request MUST be set to the local URI from the dialog state [3] rfc3261 SIP-URI = "sip:" [ userinfo ] hostport uri-parameters [ headers ]
