Crash bug on reply
by Alex Balashov 16 May '14

16 May '14

I'm running a version of Kamailio from commit a7dc504075d3b5c74c6af6a3216338a0d604d1d8 (18 Feb), so I'm not sure if this has been fixed. Anyway, I was testing a TCP client and the dialog went stale and was timed out by the dialog module using a local BYE. One of the endpoints responded to the BYE with a 481 message, and Kamailio appears to have crashed on this. (gdb) where #0 0xb717c432 in t_reply_matching (p_msg=0xb7419990, p_branch=0xbfe26e98) at t_lookup.c:987 #1 0xb717f52a in t_check_msg (p_msg=0xb7419990, param_branch=0xbfe26e98) at t_lookup.c:1129 #2 0xb71800e4 in t_check (p_msg=0xb7419990, param_branch=0xbfe26e98) at t_lookup.c:1171 #3 0xb71aa189 in reply_received (p_msg=0xb7419990) at t_reply.c:2187 #4 0x0809fd8d in do_forward_reply (msg=0xb7419990, mode=-1289507656) at forward.c:777 #5 0x080eafb5 in receive_msg ( buf=0x82d6800 "SIP/2.0 481 Unknown Dialog\r\nVia: SIP/2.0/UDP 208.52.173.18;branch=z9hG4bK931e.95a61f6", '0' <repeats 25 times>, ".0\r\nTo: <sip:+14046822836@208.52.173.18;user=phone>;tag=SDjfglb99-ac3f4687+1+f2d10012+a5eff02c\r\nFrom: <sip:+1404xxxxxxx@yyyyyyyyyy.net;user=phone>;tag=acd791cf4\r\nCSeq: 24980 BYE\r\nCall-ID: 3f7eb5b5-57ca-4de0-80eb-4d8f28ceb7ca\r\n\r\n", len=337, rcv_info=<value optimized out>) at receive.c:273 #6 0x08184cd8 in udp_rcv_loop () at udp_server.c:536 #7 0x080b0f10 in main_loop () at main.c:1617 #8 0x080b4234 in main (argc=11, argv=0xbfe27374) at main.c:2533 The actual crash is here: (gdb) frame 0 #0 0xb717c432 in t_reply_matching (p_msg=0xb7419990, p_branch=0xbfe26e98) at t_lookup.c:987 987 (p_msg->callid->body.len != p_cell->uas.request->callid->body.len || And, it would seem that the cause is that is p_cell->uas.request == NULL: (gdb) print p_cell->uas.request $1 = (struct sip_msg *) 0x0 This is all the information I have, and unfortunately I don't think I can reproduce this crash. -- Alex -- Alex Balashov - Principal Evariste Systems LLC Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ Please be kind to the English language: http://www.entrepreneur.com/article/232906

Call Throttling based on SIP Server
by Rahul MathuR 16 May '14

16 May '14

Hello, I've run into a situation where I want to throttle the number concurrent calls proxied by Kamailio based upon the SIP Server through which they are intended to go to the end point. The network diagram is somewhat like - UACs (n) -------> Kamailio (on public IP) ------ > SIP Servers (m) (on public IPs) ------------> UACs or TerminationsGateways So basically, n UACs registered to m SIP Servers via Kamailio (working as a proxy). And now I want to put the limitation on all the concurrent calls going to different SIP Servers. Say for an example, only 100 concurrent calls could be setup for SIP Server 'a' , 50 for SIP Server 'b' so on and so forth. I tried checking the different modules but could not find any clue as to how to achieve this through configuration. Now, I can try tweaking a tad of the code to send '403 Forbidden' message from receive.c (although I am not sure whether this is the correct place to do something like this..) I'd be grateful if somebody can throw light on how to achieve this. Please can someone help on this. -- Warm Regds. MathuRahul

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#427 - kamailio sometimes crash when handling failure events User who did this - Daniel-Constantin Mierla (miconda) ---------- I suspect that some event_route or rtimer route execution is messing the reference count for dialog, because of pre-post-script callbacks. Can you apply the attached patch that logs when the reference is incremented from zero. It will print once for creating the dialog, but I want to see if its getting again to 0 and then incremented. Also, can you list all event_route blocks you are using? Or alternative, share the config file somehow. ---------- One or more files have been attached.

[tracker] Task opened: sdp_keep_codecs_by_name also removes dtmf/telephone-event

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Morten Tryfoss (mtryfoss) Attached to Project - sip-router Summary - sdp_keep_codecs_by_name also removes dtmf/telephone-event Task Type - Bug Report Category - Modules kamailio Status - Unconfirmed Assigned To - Operating System - All Severity - Low Priority - Normal Reported Version - 4.1 Due in Version - Undecided Due Date - Undecided Details - As the subject says. When running for example sdp_keep_codecs_by_name("ALAW"), it also removes dtmf from sdp. I do not think this should be the correct behaviour?
