Hello. We use 2 kamailio servers cluster and we have porblems with db. Database failed pecause of error: Could not execute Write_rows_v1 event on table production.location; Duplicate entry 'uloc-54aae947-86d-a67' for key 'ruid_idx', Error_code: 1062; handler error HA_ERR_FOUND_DUPP_KEY; the event's master log FIRST, end_log_pos 380, Internal MariaDB error code: 1062 But a location table no row 'ruid_idx' and no entry uloc-54aae947-86d-a67. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/30

Re: [sr-dev] Is there a sense in calling run_onsend() after the msg_send() function?
by Lucian Balaceanu 08 Sep '15

08 Sep '15

Hi Daniel, I must admit this run_onsend() patch for stateful replies creation was not quite a success story. However, I think it serves a practical purpose, for example in Homer tracing and could be useful for the community. Again, I propose my past solution, with some questions: 1. I am unsure if the place I introduced the run_onsend call is appropriate since the buf used for msg_send is constructed build_res_buf_from_sip_req and build_res_buf_from_sip_res calls. 2. Also, we can maybe unite these if call branches I created: send_res = msg_send(&uas_rb->dst, buf, res_len); send_res = SEND_PR_BUFFER( uas_rb, buf, res_len ); 3. Do you think a get_send_socket snippet as follows should be inserted before the /*if (onsend_route_enabled(SIP_REPLY)){*/ : if(dst.send_sock == NULL) { dst.send_sock=get_send_socket(msg, &dst.to, dst.proto); if (dst.send_sock==0){ LM_ERR("cannot forward reply\n"); } } Thank you, Lucian On 10/29/2014 02:15 PM, Daniel-Constantin Mierla wrote: > Hello Lucian, > > I applied your patch with some fixes. > > I haven't checked with stateful replies, at some point a function from > core should be used.

[kamailio] Unquoted IPv6 Contact header alias parameter causes issues with Asterisk (PJSIP) & TOPOH module (#120)
by Anthony Messina 15 Jul '15

15 Jul '15

When using Kamailio from the master branch, I'm encountering an issue where IPv6 contact address aliases that are added via ```set_contact_alias()``` for WebSocket connections (for example) are unquoted and create problems for Asterisk: ``` pjsip:0 <?>: sip_transport. Error processing 3633 bytes packet from UDP 10.0.0.1:5060 : PJSIP syntax error exception when parsing 'Request Line' header on line 11 col 129: ``` and TOPOH garbles the Request-URI when processing the ACK: ``` WARNING: sanity [sanity.c:236]: check_ruri_scheme(): failed to parse request uri [�a�{1me▒s�na@50�9��1.�8:�2v0;i��a��=11>7�n7x>10O�2v0~1] ``` I have tested this with CSipSimple nightly branch (PJSIP) Asterisk 13.2.0 (PJSIP), Google Chrome 41.0.2272.118, and Firefox 37 and all fail to handle the Contact alias parameter properly.

[kamailio] lookup_branches and rtpengine_manage (#53)
by ovoshlook 04 Jun '15

04 Jun '15

Hello. I need parallel forking calls with the same username. (Call to all contacts with name for example User123), my endpoints may be WebSocket based and standart UDP endpoints. And I use rtpengine_manage for managing calls wor webphones and standart softh/hard phones. I get all contacts manually and than at the branch route set rtpengine_manage settings for every call. It works fine but it works for one kamailio server. When I use 2 kamailio servers as load balansers Server that handle call get all endpoints from location but call to only one, that registred only at ths server for example I call user123 I have 3 contacts user123(a)1.2.3.4 - was registered at kamailio 1 user123(a)3.2.1.4 - was registered at kamailio 2 user123(a)4.3.2.1 - was registered at kamailio 1 So if call goes through kamailio 1 it call only to user123(a)1.2.3.4 and user123(a)4.3.2.1 I use this settings for usrloc at 2 kamailios to share all table between 2 servers modparam("usrloc", "db_url", DBURL) modparam("usrloc", "db_mode", 3) modparam("usrloc", "user_column", "username") modparam("usrloc", "contact_column", "contact") modparam("usrloc", "expires_column", "expires") modparam("usrloc", "q_column", "q") modparam("usrloc", "callid_column", "callid") modparam("usrloc", "cseq_column", "cseq") modparam("usrloc", "methods_column", "methods") modparam("usrloc", "cflags_column", "cflags") modparam("usrloc", "user_agent_column", "user_agent") modparam("usrloc", "received_column", "received") modparam("usrloc", "socket_column", "socket") modparam("usrloc", "path_column", "path") modparam("usrloc", "ruid_column", "ruid") modparam("usrloc", "instance_column", "instance") modparam("usrloc", "use_domain", 1) and this code for calling them [GET_CONTACTS] { sql_query("ca", "select contact from location where username='$tU'", "ra"); xlog("rows: $dbr(ra=>rows) cols: $dbr(ra=>cols)\n"); if($dbr(ra=>rows)>0){ $var(i)=0; while($var(i)<$dbr(ra=>rows)){ xlog("L_INFO","SQL query return contact {$dbr(ra=>[$var(i),0])} for {$tU} at step {$var(i)}\n"); if ($dbr(ra=>[$var(i),0])=~"transport=ws"){ xlog("L_INFO", "This is a Websocket call to endpoint"); sql_pvquery("ca", "select received from location where contact='$dbr(ra=>[$var(i),0])'","$var(recieved)"); $du=$var(recieved); xlog("L_INFO","SQL query return recieved {$var(recieved)} for {$tU}. Destination is {$du}\n"); append_branch("sip:$tU@$(du{s.select,1,:})"); } else { xlog("L_INFO", "This is a classic UDP call to endpoint"); $var(recieved)=''; sql_pvquery("ca", "select received from location where contact='$dbr(ra=>[$var(i),0])'","$var(recieved)"); xlog("L_INFO", "SQL query return RECIEVED {$var(recieved)}"); if ($var(recieved)==0){ xlog("L_INFO", "Recieved string is EMPTY"); $du="sip:"+$(dbr(ra=>[$var(i),0]){s.select,1,@}); } else { xlog("L_INFO", "Recieved string is {$var(recieved)}"); $du=$var(recieved); } $var(UDP_contact)="sip:"+$(dbr(ra=>[$var(i),0]){s.select,1,@}); append_branch("sip:$tU@$(du{s.select,1,:})"); xlog("L_INFO","Classic Destination URI is {$dbr(ra=>[$var(i),0])} for {$tU}}. Destination is {$du}\n"); } $var(i) = $var(i) + 1; } } t_on_branch("1"); return; } } } branch_route[1]{ if($du=~"transport=ws"){ xlog("L_INFO","Websocket Branch is {$du} for {$tU}\n"); rtpengine_manage("internal extenal force trust-address replace-origin replace-session-connection ICE=force RTP/SAVPF"); t_on_reply("REPLY_FROM_WS"); } else{ xlog("L_INFO","UDP Branch is {$du)} for {$tU}\n"); rtpengine_manage("replace-origin replace-session-connection ICE=remove RTP/AVP"); t_on_reply("MANAGE_CLASSIC_REPLY"); } } When it try to branch endpoint without registration at server that handle call I get errors that tm module can not build Via header *via_builder(): TCP/TLS connection (id: 0) for WebSocket could not be found* *ERROR: <core> [msg_translator.c:1725]: build_req_buf_from_sip_req(): could not create Via header* *ERROR: <core> [forward.c:607]: forward_request(): ERROR: forward_request: building failed* UDP calls get errors something like above (sorry than can not share error code, This situation not often). So I think I have this trouble because I use manually handling call and tried to substitute to lookup_branches function. but I have no Idea how to set rtpengine_manage paraments for each endpoint depending this is websocket or standart call. IF there is write problem for callings thhrough 2 kamailios as load balansers please let me know about how to set rtpengine_manage parametrs wor endpoints for every fork. If not- can you tell me how I can call to all endpoints endepending of registration server (kamailio 1 or 2). But with another side I can not understand why kamailio 2 don't see registrations at kamailio1 (or 1 from 2). May be this is trouble of usrloc module. That's why I write this problem here.

[kamailio] introduce RUN_DIR (#80)
by Victor Seva 03 Jun '15

03 Jun '15

In order to get rid of any occurrence of ```/tmp``` in modules, introduce a ```RUN_DIR``` make option and every module should honor it default could be ```/var/run/$(NAME)``` Related to #48 --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/80

[kamailio] multiple /tmp file vulnerabilities (#48)
by Victor Seva 21 May '15

21 May '15

Reported by: Helmut Grohne <helmut(a)subdivi.de> The kamailio package now installs /etc/kamailio/kamailio-basic.cfg which can be selected via the CFGFILE= setting in /etc/default/kamailio. The configuration contains: ``` modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo") ``` This setting is insecure and may allow local users to elevate privileges to the kamailio user. The issue extends to kamailio-advanced.cfg. It seems that this is due to an incomplete fix of #712083. Looking further, the state of /tmp file vulnerabilities in kamailio looks worrisome. Most of the results of the following command (to be executed in the kamailio source) are likely vulnerable if executed: ``` grep '/tmp/[a-z0-9_.-]\+$\$\$$\?$[" ]\|$$' -r . ``` Granted, some of the results are examples, documentation or obsolete. But quite a few reach the default settings: * kamcmd defaults to connecting to unixs:/tmp/kamailio_ctl. * The kamailio build definitely is vulnerable as can be seen in utils/kamctl/Makefile. More research clearly is required here. Given these findings, the security team may want to veto the inclusion of kamailio in a stable release, which would be very unfortunate as kamailio is quite a unique piece of software with little competitors in its field.

[kamailio] kamailio doesn't provide number of registered users stat when usrloc in db_mode=3 (#113)
by mading087 21 May '15

21 May '15

Running latest 4.2 with usrloc in db_mode=3. It seems "kamctl stats usrloc" or "kamctl ul show" always shows 0 registered users even when there are registered users (location table has entries). This looks like a bug? --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/113
