[kamailio/kamailio] fr_timer documentation mistake (Issue #3939)
by Dmitry Sinina 05 Apr '25

05 Apr '25

Documentation https://www.kamailio.org/docs/modules/devel/modules/tm.html#tm.p.fr_timer says: >Timer which hits if no **final reply** for a request or ACK for a negative INVITE reply arrives (in milliseconds). Looks like it is not correct description - fr_timer value works until 1xx(not **final**) response received and then timer restarted with fr_inv_timer value there: https://github.com/kamailio/kamailio/blob/master/src/modules/tm/t_reply.c#L… Looks like old doc from sip router https://sip-router.org/wiki/ref_manual/timers explains it correctly: > fr_timer This timer is used for all SIP requests. It hits if no reply for an INVITE request or other request has been received (F in milliseconds). If a provisional reply is received for an INVITE (any 1xx), then the fr_inv_timer will be used instead. And if no replies (at all) for an INVITE are received before `fr_timer` hits, the transaction is terminated with a 408 in failure route. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3939 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] tcp_timer_check_connections() logs on CRITICAL and is not caught by event_route[tcp:timeout] (Issue #3995)
by Fritjof Höst 02 Apr '25

02 Apr '25

### Description Hi! We are in the progress of upgrading from Kamailio 5.5 to 5.8. During our testing we have noticed a new error being reported from Kamailio. We don’t see any other errors following it. ```jsx /usr/sbin/kamailio[201]: CRITICAL: <core> [core/tcp_main.c:5544]: tcp_timer_check_connections(): message processing timeout on connection id: 67896 (state: 3) - closing ``` It does seem to be [new code](https://github.com/kamailio/kamailio/blob/master/src/core/tcp_main.c#… in Kamailio reporting this issue. Given that this is a fairly expected thing, cleaning up a connection which receives no traffic within the given time, is there a need for it to be reported on CRITICAL? I’d also expect it to be caught by ``` event_route[tcp:timeout] { xlog("L_INFO","connection $conid timeouts (unanswered keepalives)"); } ``` given that [the description](https://www.kamailio.org/docs/modules/stable/modules/tcpops.ht… of this one is `Called for connection timeouts (unanswered keepalives).`. ### Troubleshooting We don't have any way to reproduce it, we are still investigating it to figure out the cause. It happens around every 2 hours, so we think there might some some scheduled test or job running in our test system causing this. ### Additional Information * **Kamailio Version** - 5.8.3 * **Operating System**: Debian 12 AMI from the AWS Marketplace. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3995 You are receiving this because you are subscribed to this thread.

It adds a new parameter `enable_shared_ctx` in `tls` module that if set to 0, preserves the old behavior and if set to 1 (other than 0 tbh), it creates a single SSL context that is being shared. This have the effect of using way less memory when initialized as well, but also minimizes (can't say it fixes the problem) the `tls.reload` memory increase. I have also added a small markdown (comparison.md) file, where some comparisons where made between enabled/disabled shared context and with/without CA file (where the initial problem was occurring by the reporter). Feedback would be necessary to verify whether this patch, acts as expected and kamailio works as intented.

[kamailio/kamailio] Allow calling `route()` in `onsend_route` (Issue #4130)
by Ben Kaufman 28 Mar '25

28 Mar '25

### Description Currently calling `route()` within the `onsend_route` will cause kamailio to fail to start with an error that `command not allowed in onsend_route` ### Expected behavior While there is a limited amount of functions that can be allowed within the `onsend_route`, calling `route()` here would be done simply for code organization. #### Actual observed behavior Kamailio fails to start; ### Possible Solutions Allow `route()` to be called from `onsend_route`. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4130 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Memory usage increases everytime tls.reload is executed (Issue #3823)
by Sebastian Denz 27 Mar '25

27 Mar '25

### Description We are using Kamailio 5.7.4 on Debian 12 (from http://deb.kamailio.org/kamailio57) with rtpengine as an Edgeproxy for our clients. The instance terminates SIP/TLS (with Cliencertificates) and forwards the SIP Traffic to internal systems. After some days we are getting errors like this `tls_complete_init(): tls: ssl bug #1491 workaround: not enough memory for safe operation: shm=7318616 threshold1=8912896` First we thought Kamailio just doesnt have enough memory, so we doubled it.. But after some days the Logmessage (and Userissues) occured again. So we monitored the shmmem statistics and found that used and max_used are constantly growing til it reaches the limit. As i mentioned we are using client-certificates and so we are also using the CRL feature. We do have a systemd-timer which fetches the CRL every hour and runs 'kamcmd tls.reload' when finished. Our tls.cfg looks like this: ``` [server:default] method = TLSv1.2+ private_key = /etc/letsencrypt/live/hostname.de/privkey.pem certificate = /etc/letsencrypt/live/hostname.de/fullchain.pem ca_list = /etc/kamailio/ca_list.pem ca_path = /etc/kamailio/ca_list.pem crl = /etc/kamailio/combined.crl.pem verify_certificate = yes require_certificate = yes [client:default] verify_certificate = yes require_certificate = yes ``` After testing a bit we found that every time tls.reload is executed Kamailio consumes a bit more memory which eventually leads to all the memory being consumed which leads to issues for our users. See following example: ``` [0][root@edgar-dev:~]# while true ; do /usr/sbin/kamcmd tls.reload ; /usr/sbin/kamcmd core.shmmem ; sleep 1 ; done Ok. TLS configuration reloaded. { total: 268435456 free: 223001520 used: 41352552 real_used: 45433936 max_used: 45445968 fragments: 73 } Ok.

[kamailio/kamailio] Segfault when using kamailio 5.8.4 as a presence proxy (Issue #4102)
by Joe Mordica 27 Mar '25

27 Mar '25

### Description We are now using kamailio on the edge as a presence proxy to scale presence. We have 3 internal kamailio instances handling the actual subscriptions and publishing. This works well, however, once per 24-36hours we experience a crash on the border proxy instance. We did not experience this when using the border proxy as a presence server (there was no proxying SUBSCRIBE). ### Troubleshooting #### Reproduction I believe this is happening when a customers network randomly experiences issues where it doesn't receive our replies to subscribes (and continues to send a subscribe). Logs are below. #### Debugging Data  Here's the output while replacing any sensitive info in the payload. ``` GNU gdb (Debian 13.1-3) 13.1 Copyright (C) 2023 Free Software Foundation, Inc.

[kamailio/kamailio] [rtpengine] failure to ping rtpengine results in consistent core dump in kamailio 5.8.2 (Issue #4122)
by Brandon Armstead 26 Mar '25

26 Mar '25

### RTPEngine + RTIMER + SEGFAULT + unable to ping When unable to ping RTPEngine instances kamailio crashes. ### Troubleshooting Determined issue was related to the ping failures, resolved AWS SG issue, allowing successful pings. Issue subsequently went away. #### Reproduction Use rtpengine with RDS backend Load rtpengine with ~ 20 destinations you do not expect a response from on Use rtimer to call rtpengine.reload via jsonrpcs: ``` modparam("rtimer", "timer", "name=rtpengine;interval=60;mode=0;") modparam("rtimer", "exec", "timer=rtpengine;route=RELOAD_RTPENGINE") route[RELOAD_RTPENGINE] { xinfo("RTPEngine database reloading"); jsonrpc_exec('{"jsonrpc": "2.0", "method": "rtpengine.reload", "id": 1}'); } ``` #### Debugging Data Got a core dump -- although I deleted quickly (not thinking) as they were running instances out of disk quickly. bt full did not show much to step through all though clearly pointed to rtpengine. #### Log Messages ``` send_rtpp_command(): timeout waiting reply for command "ping" from RTPEngine <udp:10.0.X.X> ``` ### Possible Solutions TBD / do not have ping failures under heavy load. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.8.2 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_SEND_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 10.2.1 ``` * **Operating System**: ``` uname -a Linux 5.10.0-27-cloud-amd64 #1 SMP Debian 5.10.205-2 (2023-12-31) x86_64 GNU/Linux cat /proc/version Linux version 5.10.0-27-cloud-amd64 (debian-kernel(a)lists.debian.org) (gcc-10 (Debian 10.2.1-6) 10.2.1 20210110, GNU ld (GNU Binutils for Debian) 2.35.2) #1 SMP Debian 5.10.205-2 (2023-12-31) lsb_release -a No LSB modules are available.

[kamailio/kamailio] Error when sending NOTIFYs in the presence of disconnected websocket watchers (Issue #4118)
by Flavio Grossi 25 Mar '25

25 Mar '25

### Description if multiple sip websocket clients are subscribed to some UA and one of the watchers suddenly disappears (e.g. the web page is reloaded), then no NOTIFY is ever sent after issuing a `pres_refresh_watchers()`. The following error is logged: ``` WARNING: <core> [core/msg_translator.c:3007]: via_builder(): TCP/TLS connection (id: 0) for WebSocket could not be found ERROR: tm [t_msgbuilder.c:1423]: assemble_via(): via building failed ERROR: tm [t_msgbuilder.c:1614]: build_uac_req(): error while assembling Via ERROR: tm [uac.c:552]: t_uac_prepare(): Error while building message ERROR: presence [notify.c:1734]: send_notify_request(): in function tm t_request_within() ERROR: presence [notify.c:1829]: notify(): sending Notify not successful ERROR: presence [notify.c:1585]: query_db_notify(): Could not send notify for [event]=dialog ERROR: presence [presence.c:739]: pres_refresh_watchers(): sending Notify requests ``` ### Troubleshooting when the client disconnects, the old watcher is not removed from the active_watchers table, instead it coexists with the new one, but the stale connection causes the error above when sending the notify, and then all of the following watchers (even the valid ones) are skipped too. Looking at the logs, the valid watchers are not notified because the while loop [here](https://github.com/kamailio/kamailio/blob/b96bc11a54f11ec688429c057bf… is skipped because of the `goto done` line in case of errors, which happens because it fails to build the via header for the message relevant to the stale websocket connection. By breaking out of the while loop, the remaining subs in the `subs_array` are skipped. #### Reproduction Just subscribe to a sip client using a websocket-based phone, then abruptly disconnect it (e.g. by reloading the web page) and then issue a `pres_refresh_watchers()` to make it generate a notify. #### Debugging Data #### Log Messages #### SIP Traffic ### Possible Solutions I tried to use the "websocket:closed" route to purge stale connections, but to my knowledge there are no APIs to clean invalid watchers. A possible solution could be to automatically remove the watchers on disconnection and maybe skip the invalid ones without exiting from the refresh loop ### Additional Information kamailio 5.8.2 * **Operating System**: Rocky Linux 9 -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4118 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Migrate to C23 (Issue #4106)
by soroshsabz 25 Mar '25

25 Mar '25

ITNOA As you can see many defects resolve in [C17](https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2244.htm) and [C23](https://en.wikipedia.org/wiki/C23_(C_standard_revision) introduce many new language features for clean coding. So I suggest migrate codebase to C23, and if you agree with me, I can try to migrate that -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4106 You are receiving this because you are subscribed to this thread.
