[kamailio/kamailio] rtp_media_server module hard codes contact header to "rms" (Issue #3380)
by Daniel Donoghue 11 Jan '24

11 Jan '24

### Description when using rtp_media_server module in my kamailio configuration, the `rms_answer` function generates a "200 OK" with a hard-coded Contact header user. I believe it would make more sense for this to use the To user (`$tU`) as that should be who is answering. #### Reproduction ``` route { if (t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); if (is_method("INVITE") && !has_totag()) { if (!rms_answer("rms:start_long")) { t_reply("503", "server error"); } exit; } if (rms_dialog_check()) { rms_sip_request(); } } ``` #### Debugging Data n/a #### Log Messages n/a #### SIP Traffic ``` INVITE sip:+461812345678@123.123.example.com SIP/2.0.

[kamailio/kamailio] kamailio 5.7.1 as a webrtc server experiences random crashes (Issue #3563)
by themsley-voiceflex 09 Jan '24

09 Jan '24

### Description Crashed after about 30 minutes of uptime. I probably have several bug reports to post on similar lines, they may all be related or they may all be completely different but I will raise a separate bug report for each. ### Troubleshooting Tried varying SHM_MEMORY from 256 to 512 and PKG_MEMORY from 8 to 64 in various increments. None seemed to help. #### Reproduction Open kamailio on tcp port 7443 and set up webrtc to point to it for traffic. `` #### Debugging Data coredumpctl debug PID: 1186 (kamailio) UID: 990 (kamailio) GID: 988 (kamailio) Signal: 11 (SEGV) Timestamp: Wed 2023-09-13 22:39:40 UTC (8min ago) Command Line: /usr/sbin/kamailio -DD -P /run/kamailio/kamailio.pid -f /etc/kamailio/kamailio.cfg -m 256 -M 8 --atexit=no Executable: /usr/sbin/kamailio Control Group: /system.slice/kamailio.service Unit: kamailio.service Slice: system.slice Boot ID: 3fc4251c606f4c6183610573f44c46ba Machine ID: 16e913e686424f13b970f9b1044cc6b3 Hostname: kamrtc01.voiceflex.com Storage: /var/lib/systemd/coredump/core.kamailio.990.3fc4251c606f4c6183610573f44c46ba.1186.1694644780000000.zst (present) Size on Disk: 4.6M Message: Process 1186 (kamailio) of user 990 dumped core.

[kamailio/kamailio] janssonrpcc: No failover to lower prio server (Issue #3378)
by Alex Hermann 09 Jan '24

09 Jan '24

### Description I have 2 jsonrpc servers configured with different prio's. For testing, I have the servers configured to always delay the response to any request by more than the module's timout setting. The (initial) request is sent to the first server. As this one times out, I would expect a retry to go to the second servers, but instead, all retries are sent to the same server. The backup server is never contacted. This makes the whole "prio" system seem a bit useless.  ### Troubleshooting #### Reproduction ``` modparam("janssonrpcc", "server", "conn=test;addr=pc1;port=8081;priority=5;weight=10") modparam("janssonrpcc", "server", "conn=test;addr=pc1;port=8082;priority=5;weight=10") ``` ``` janssonrpc_request("test", "Test.Timeout", '[ { "Timout": 1000} ]', "route=JSONRPC_RESPONSE;retry=10;timeout=1000"); ```  #### Log Messages No useful logs are produced. I verified the described behavior on the jsonrpc server.  ``` 2023-02-23T16:59:34.585346+01:00 pc1 proxy1[340870]: INFO: janssonrpcc [janssonrpc_connect.c:361]: bev_connect(): Connecting to server pc1:8081 for conn rating. 2023-02-23T16:59:34.585420+01:00 pc1 proxy1[340870]: INFO: janssonrpcc [janssonrpc_connect.c:361]: bev_connect(): Connecting to server pc1:8082 for conn rating. 2023-02-23T16:59:34.585446+01:00 pc1 proxy1[340870]: INFO: janssonrpcc [janssonrpc_connect.c:290]: bev_connect_cb(): Connected to host pc1:8081 2023-02-23T16:59:34.585462+01:00 pc1 proxy1[340870]: INFO: janssonrpcc [janssonrpc_connect.c:290]: bev_connect_cb(): Connected to host pc1:8082 2023-02-23T17:05:10.903398+01:00 pc1 proxy1[340870]: WARNING: janssonrpcc [janssonrpc_request.c:247]: schedule_retry(): Number of retries exceeded. Failing request. ``` ### Possible Solutions  Retry in combination with a timeout and prio's is a bit tricky. When do what? Just retrying on the first prio makes the lower prio servers completely useless, while going to the next prio on every retry skips possibly useful high-prio servers and may exhaust the number of candidate servers very fast. Best solution IMHO would be to first try every server in the highest prio, before going to the next prio. Do not do (exponential) backoff between these steps. If there are still retries remaining after that, wrap around to the highest prio with the exponentional backoff delay. With the above, failover considers all servers and failover between servers is fast while not overloading a single server. BTW. If I configure multiple servers per prio, it seems to randomly select one of them for every (re)try. It never selects one form the next prio. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` 5.6.1 ``` * **Operating System**:  ``` (paste your output here) ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3378 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] pv: hfl(name)[N] for negative index bug (Issue #3653)
by Xenofon Karamanos 08 Jan '24

08 Jan '24

### Description I am working on extending $hfl and $hflc to support some more headers. During some experimentation, I stumbled into some weird behavior regarding $(hfl(Route)[-1]) and negative indexing of $hfl pseudo-variable (also for Via, Contact). Per the [docs ](https://www.kamailio.org/wikidocs/cookbooks/devel/pseudovariables/#hflname-header-field-with-list-of-bodies ): -1 index should print the last header found and so on (as stated by $hdr $hfl). Right now, -1 produces null, and from -2 and onwards it prints correctly from the last one to the first one. ### Troubleshooting #### Reproduction ``` #kamailio.cfg ... request_route { xlog("L_INFO", "Route headers hdr: $hdr(Route)\n"); xlog("L_INFO", "Route headers hfl: $hfl(Route)\n"); xlog("L_INFO", "Route headers count: $hflc(Route)\n"); xlog("L_INFO", "Route headers 0: $(hfl(Route)[0])\n"); xlog("L_INFO", "Route headers 1: $(hfl(Route)[1])\n"); xlog("L_INFO", "Route headers 4: $(hfl(Route)[4])\n"); xlog("L_INFO", "Route headers -1: $(hfl(Route)[-1])\n"); xlog("L_INFO", "Route headers -2: $(hfl(Route)[-2])\n"); xlog("L_INFO", "Route headers -3: $(hfl(Route)[-3])\n"); ... } ``` Seng a SIP message containing Route (but also applicable for VIA, Contact headers): ``` OPTIONS_MSG_2CONTACTS="OPTIONS sip:example.com SIP/2.0 Via: SIP/2.0/UDP 192.168.1.100:5060;branch=z9hG4bK123456789 Max-Forwards: 70 From: <sip:bob@example.com>;tag=123456789 To: <sip:alice@example.com> Call-ID: 987654321(a)192.168.1.100 CSeq: 1 OPTIONS Contact: <sip:bob@example.com>;expires=3600,<sip:bob2@example.com>;expires=3600,<sip:bob3@example.com>;expires=3600 Route: <sip:server1.example.com;lr;ftag=1234>, <sip:server2.example.com;lr;ftag=5678>, <sip:server3.example.com;lr;ftag=9012> Route: <sip:server4.example.com;lr;ftag=1234>, <sip:server5.example.com;lr;ftag=5678> Content-Length: 0 " echo -e "$OPTIONS_MSG_2CONTACTS" | nc -u localhost 5060 ``` See logs for logging details. #### Log Messages  ``` INFO: {1 1 OPTIONS 987654321(a)192.168.1.100} <script>: Route headers hdr: <sip:server1.example.com;lr;ftag=1234>, <sip:server2.example.com;lr;ftag=5678>, <sip:server3.example.com;lr;ftag=9012> INFO: {1 1 OPTIONS 987654321(a)192.168.1.100} <script>: Route headers hfl: <sip:server1.example.com;lr;ftag=1234> INFO: {1 1 OPTIONS 987654321(a)192.168.1.100} <script>: Route headers count: 5 INFO: {1 1 OPTIONS 987654321(a)192.168.1.100} <script>: Route headers 0: <sip:server1.example.com;lr;ftag=1234> INFO: {1 1 OPTIONS 987654321(a)192.168.1.100} <script>: Route headers 1: <sip:server2.example.com;lr;ftag=5678> INFO: {1 1 OPTIONS 987654321(a)192.168.1.100} <script>: Route headers 4: <sip:server5.example.com;lr;ftag=5678> INFO: {1 1 OPTIONS 987654321(a)192.168.1.100} <script>: Route headers -1: <null> INFO: {1 1 OPTIONS 987654321(a)192.168.1.100} <script>: Route headers -2: <sip:server5.example.com;lr;ftag=5678> INFO: {1 1 OPTIONS 987654321(a)192.168.1.100} <script>: Route headers -3: <sip:server4.example.com;lr;ftag=1234> ``` ### Possible Solutions  In https://github.com/kamailio/kamailio/blob/e59c4415707f0995a0d5315b5601ae518…, the count should start at 0 ie. ``` n=0; // not n=1; ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` (paste your output here) ``` * **Operating System**:  ``` (paste your output here) ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3653 You are receiving this because you are subscribed to this thread.
