Questions on http_async_query() in event_route[xhttp:request] and async best practices for Kamailio
by James Aylett 04 Jun '21

04 Jun '21

Hi, I am using Kamailio v5.2 as a WebRTC proxy for SIP clients, as part of my setup I call a REST API before calling ws_handle_handshake() in event_route[xhttp:request] using http_client_query() to authenticate and retrieve some user details (routing etc) for the user connected via WebSockets. This worked fine until increased load on the system meant API responses were slow, this caused a knock-on effect to existing connected users. Specifically, we saw mass WebSocket disconnects for existing connected users - believed to be due to using too aggressive proxy timeout settings on our reverse proxy in front of Kamailio. My understanding is that event_route[xhttp:request] uses the shared SIP TCP worker threads, so potentially could slow API requests over the network block all the handlers? Could this potentially impact the keepalive processes used by the WebSocket module to check existing WebSocket connections? We were using ping keepalives, again with pretty aggressive timers... To resolve this issue, I am looking at whether I can call API requests asynchronously so that TCP workers are not blocked, my first thought was to use http_async_query() in event_route[xhttp:request] and call ws_handle_handshake() in the HTTP_REPLY route when the API call had completed, but I get "ERROR: websocket [ws_handshake.c:143]: ws_handle_handshake(): retrieving connection". I presume then this approach is a deadend, looking at newer kamailio versions 5.5, there doesn't seem to be any way to do this, correct? Instead of using http_async_query() in event_route[xhttp:request], I presume I could set a short timeout in http_client_query(), but my concern is new WebSocket connections could still impact and block existing ones in this case... My other thought was to move my API call out from the event_route[xhttp:request] into my route handler for REGISTER requests, thinking I could offload new register requests to async workers and move the API call there so as to not block existing connections. Does this seem like a reasonable approach to the problem? Given my current script does not use any async workers, how would one go about optimising the number of plain SIP TCP workers to async workers, are there any guides for this? In general, for any potentially blocking "APIs" or calls over the network, is it best practice to offload them into async workers. For example, we run RTPEngine on separate hosts to Kamailio so should I be wrapping rtpengine_offer/answer calls into async workers in case of a slow network? Apologies for the long text, but I would really appreciate any help to understand these problems. Thank you

Need help analyze crash

Hi all, Today I upgraded Kamailio to 5.4.5 and a random crash was just reported in our crash monitoring script. Below is the output of the crash: #3 0x00007fa149ebe58d in ??

handle_ruri_alias() and multiple aliases
by Denys Pozniak 02 Jun '21

02 Jun '21

Hello! I need help understanding how the *handle_ruri_alias()* function works. *Call-flow:* Upstream operator -> Kamailio Proxy -> Edpoint. The upstream operator in the initial SIP INVITE in the Contact field sends us an alias parameter, in turn, our Kamailio Proxy adds its own too. The Contact after the Proxy looks something like this: *Contact: <sip:10.0.0.115:5060;alias=10.0.0.115~5060~1;alias=3.3.3.3~5060~1>* When the Endpoint sends us a SIP BYE, then the *handle_ruri_alias()* absorbs not the last alias, but the first one, and this leads to the incorrect formation of a $du. The RURI after the Proxy looks something like this: *Request-Line: BYE sip:10.0.0.115:5060;alias=3.3.3.3~5060~1 SIP/2.0* The first thing that comes to mind is a modification of the original Contact field with storing it's within a dialogue ... Is it possible to elegantly solve this problem? -- BR, Denys Pozniak

kamailio 5.4.5 crash after dialog [dlg_hash.c:1182]: next_state_dlg(): bogus event 2 in state 5 for dlg
by Trevor Hemsley 02 Jun '21

02 Jun '21

Hi We've seen a few occurrences of this crash since we implemented kamailio 5.4.5 for our inbound call traffic. Preceding the crash we always get a message in the logs about "dialog [dlg_hash.c:1182]: next_state_dlg(): bogus event 2 in state 5 for dlg" and whenever we see that message, we get the crash. Jun 1 10:12:14 thissystem /usr/sbin/kamailio[20001]: CRITICAL: {2 1 INVITE 6787142-3831531134-1330894187(a)some.telco.domain} dialog [dlg_hash.c:1182]: next_state_dlg(): bogus event 2 in state 5 for dlg 0x7fae153d3cf0 [3973:6059] with clid '82608924-3831089984-1833452161(a)some.telco.domain' and tags '3831089984-684203260' '' The crash happens on line 879 of https://github.com/kamailio/kamailio/blob/master/src/modules/dialog/dlg_db_… SET_STR_VALUE(values+7, cell->bind_addr[DLG_CALLER_LEG]->sock_str); Looking at gdb, I see that cell->bind_addr[DLG_CALLER_LEG] == 0 so trying to use it results in the segfault. I have thought about patching that to check for bind_addr being set and bypassing that line if not but I do not think it's the right fix though it probably would avoid the current crash (and do odd things later instead!). I did check that everything else in that function that uses DLG_CALLER_LEG is set correctly and it appears that it is - or at least if not correctly then they are at least set! The "bogus event 2 in state 5" message is coming out from line 1143 in src/modules/ims_dialog/dlg_hash.c case DLG_EVENT_RPL1xx: switch (dlg->state) { case DLG_STATE_UNCONFIRMED: case DLG_STATE_EARLY: dlg->state = DLG_STATE_EARLY; break; default: log_next_state_dlg(event, dlg); } break; (I didn't really understand why it would set dlg->state = DLG_STATE_EARLY if it's already DLG_STATE_EARLY but...) I have a couple of core dumps of this from the last day or two - usually seems to crash at least once a week on our pair of kamailio inbound servers. If there's any more info I can provide to help fix this properly rather than my proposed bodge then feel free to ask.

UAC module register originating from private interface on server
by Jonathan Hunter 02 Jun '21

02 Jun '21

Hi, I am working with the UAC module and trying to register with providers, and can see that kamailio keeps sending the REGISTER from the private IP address socket on the server (eth0). Is it possible to set the default socket or send socket for the REGISTER message that gets sent out via kamailio? I am running version 4.4.7. I notice SIP OPTIONS are being sent out from the public IP address (eth1) on the server (as I have set socket in dispatcher) and was hoping for same behaviour with uac module. Please can anyone advise? Many thanks Jon Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10
