[kamailio/kamailio] Segfault in pua_dialoginfo.c when starting up with a dialog in the database (Issue #3743)
by Gianluca Nitti 22 May '24

### Description Kamailio segfaults on startup. After a bit of digging, it looks like the issue is caused by trying to publish something related to an expired dalog which is present in the database: ``` kamailio=# select * from dialog; id |

[kamailio/kamailio] registrar: adding contact and UA to xavp_cfg (Issue #3753)
by nirvanr-nextiva 30 Apr '24

30 Apr '24

### Description We are using Kamailio as a 'mid-registrar', and saving the location record (i.e calling registrar.save()) in the reply-route depending on received status code from other registrar. We noticed the saved location record had the contact URI (incl. instance id) and UA from response message; instead we would like to use the contact and UA from the original request. This feature change is similar to what was added for `tcpconn_id` in PR: https://github.com/kamailio/kamailio/pull/3430. i.e. we would set the request's contact URI and UA in `xavp_cfg` variable. Then `registrar.save.c` would use the contact and UA from `xavp_cfg`. Thanks. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3753 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] ndb_reids module in event_route[tcp:closed] route block error: "no redis context for server" (Issue #3768)
by liangbaolin 25 Apr '24

25 Apr '24

### Description The process of using kamailio prompts the following error： ERROR: ndb_redis [redis_client.c:963]: redisc_exec(): no redis context for server: srvN I did not encounter similar errors in version 5.4.8, and there were no similar errors in other routing blocks. Suspect that the new core version has unknown logical issues with the routing block of the module in event_route.  #### Log Messages  ``` 2024-02-26T03:39:11.161557654Z 51(97) DEBUG: <core>

[kamailio/kamailio] Option to not add received via param (Issue #3515)
by zusrut 15 Apr '24

15 Apr '24

### Description Hello. Probably I'm doing something wrong but I can't get rid of **received** parameter in the **Via** header in responses from kamailio by websocket transport. According [RFC 7118](https://datatracker.ietf.org/doc/rfc7118/): `` When a SIP WebSocket Server receives a request, it MAY decide not to add a "received" parameter to the top Via header. Therefore, SIP WebSocket Clients MUST accept responses without such a parameter in the top Via header regardless of whether the **Via** "sent-by" field contains a domain name. `` ### Expected behavior For responses to websocket transport have a way to not add **received** parameter in **Via** header #### Actual observed behavior Responses to OPTION or REGISTER methods trough websocket got **received** containing IP we want to not show to the end users. ### Possible Solutions maybe add a param in **tm** module or something ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.2.1 (x86_64/linux) ``` and ``` kamailio 5.6.1 (x86_64/linux) b36a13 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3515 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] User id conflict between kamctl et. al. and Linux OS installations (Issue #3752)
by Mark Warren 10 Apr '24

10 Apr '24

### Description After installing kamailio on Ubuntu (20.04 and 22.04) using normal kamailio.org instructions, things work fine. However, a developer is working on a large project as root, and occasionally restarts kamailio with the command "kamctl <start|stop|restart>", rather than the OS command "systemctl <stop|start|restart> kamailio". After that, any attempt to restart or check status using systmectl fails, and rebooting the server occasionally fails to restart kamailio. ### Troubleshooting #### Reproduction Install ubuntu 22.04 or 20.04. When up and running, try this: `systemctl status kamailio` (everything looks good) `ps -C kamailio -o comm,uid,euid,pid,ppid` (all happy, Kamailio running as user kamailio) `kamctl restart` `ps -C kamailio -o comm,uid,euid,pid,ppid` (Yes it's running, but as root, not kamailio) `systemctl status kamailio` (FAILS, 20.04 reports "Failed to start", 22.04 reports "kamailio.service: Deactivated successfully") `systemctl restart kamailio` (FAILS - same reports as preceding "status" command) #### Debugging Data  #### Log Messages  After command systemctl restart kamailio: ``` Feb 9 18:30:02 usdc2-lab-drproxy02 kamailio: INFO: <core> [core/sctp_core.c:74]: sctp_core_check_support(): SCTP API not enabled - if you want to use it, load sctp module Feb 9 18:30:02 usdc2-lab-drproxy02 kamailio: INFO: <core> [core/tcp_main.c:5042]: init_tcp(): using epoll_lt as the io watch method (auto detected) Feb 9 18:30:02 usdc2-lab-drproxy02 /usr/sbin/kamailio[2388]: INFO: rr [../outbound/api.h:52]: ob_load_api(): unable to import bind_ob - maybe module is not loaded Feb 9 18:30:02 usdc2-lab-drproxy02 /usr/sbin/kamailio[2388]: INFO: rr [rr_mod.c:177]: mod_init(): outbound module not available Feb 9 18:30:02 usdc2-lab-drproxy02 /usr/sbin/kamailio[2388]: INFO: auth [auth_mod.c:345]: mod_init(): qop set, but nonce-count (nc_enabled) support disabled Feb 9 18:30:02 usdc2-lab-drproxy02 /usr/sbin/kamailio[2388]: INFO: <core> [main.c:2779]: main(): processes (at least): 32 - shm size: 67108864 - pkg size: 8388608 Feb 9 18:30:02 usdc2-lab-drproxy02 /usr/sbin/kamailio[2388]: INFO: <core> [core/udp_server.c:154]: probe_max_receive_buffer(): SO_RCVBUF is initially 212992 Feb 9 18:30:02 usdc2-lab-drproxy02 /usr/sbin/kamailio[2388]: INFO: <core> [core/udp_server.c:206]: probe_max_receive_buffer(): SO_RCVBUF is finally 425984 Feb 9 18:30:02 usdc2-lab-drproxy02 /usr/sbin/kamailio[2388]: INFO: <core> [core/udp_server.c:154]: probe_max_receive_buffer(): SO_RCVBUF is initially 212992 Feb 9 18:30:02 usdc2-lab-drproxy02 /usr/sbin/kamailio[2388]: INFO: <core> [core/udp_server.c:206]: probe_max_receive_buffer(): SO_RCVBUF is finally 425984 Feb 9 18:30:02 usdc2-lab-drproxy02 /usr/sbin/kamailio[2388]: ERROR: <core> [core/tcp_main.c:3162]: tcp_init(): bind(c, 0x7f49b0475c74, 16) on 127.0.0.1:5060 : Address already in use Feb 9 18:30:02 usdc2-lab-drproxy02 /usr/sbin/kamailio[2388]: INFO: <core> [core/sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions Modify kamctl et. al. to call systemctl for start, stop, restart commands.

[kamailio/kamailio] Kamailio segfaults when KEMI functions are invoked from app_python script (Issue #3746)
by David Minh Phan 07 Apr '24

07 Apr '24

### Description Kamailio segfaults when KEMI functions are invoked from app_python script ### Troubleshooting The same code was running ok with the 5.6 branch. It seems that the function sr_apy_kemi_exec_func_ex has been re-written in 5.7 with the following main changes : - The long IF/ELSE statement was replace by a FOR loop - The call to PyArg_ParseTuple function was replaced by the call to PyList_GetItem ==> **This seems to be the cause. The value returned by this function is alway NULL** #### Reproduction Any call to KSR.pv.seti function from a PYTHON 2 script would cause this error. #### Log Messages ``` sbin/kamailio[18449]: ERROR: app_python [apy_kemi.c:280]: sr_apy_kemi_exec_func_ex(): null parameter - func: seti idx: 0 argc: 2 Feb 6 11:34:16 .../sbin/kamailio[18509]: CRITICAL: <core> [core/pass_fd.c:281]: receive_fd(): EOF on 37 Feb 6 11:34:16 .../sbin/kamailio[18380]: ALERT: <core> [main.c:793]: handle_sigs(): child process 18449 exited by a signal 11 Feb 6 11:34:16 .../sbin/kamailio[18380]: ALERT: <core> [main.c:796]: handle_sigs(): core was not generated Feb 6 11:34:16 .../sbin/kamailio[18380]: INFO: <core> [main.c:818]: handle_sigs(): terminating due to SIGCHLD Feb 6 11:34:16 .../sbin/kamailio[18509]: INFO: <core> [main.c:874]: sig_usr(): signal 15 received Feb 6 11:34:16 .../sbin/kamailio[18502]: INFO: <core> [main.c:874]: sig_usr(): signal 15 received Feb 6 11:34:16 .../sbin/kamailio[18495]: INFO: <core> [main.c:874]: sig_usr(): signal 15 received Feb 6 11:34:16 .../sbin/kamailio[18482]: INFO: <core> [main.c:874]: sig_usr(): signal 15 received ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3746 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Topos breaks early dialog transactions on multi-homed kamailio instances using enable_double_rr and versions >= 5.6.5 (Issue #3757)
by George Diamantopoulos 05 Apr '24

### Description All kamailio versions on the 5.7.x train and additionally point release 5.6.5 break early dialog transactions, at least when the following conditions are (cumulatively) met: * topos-redis is enabled (haven't tested other storage backends yet, let me know if needed) * kamailio is multihomed * enable_double_rr is enabled (the default) ### Troubleshooting #### SIP Traffic Here's an exchange demonstrating the problem: ``` kamailio instance ──────────┬──────────────────┬───────── internal external peer 172.30.154.1:5060 185.73.43.241:5060 195.167.21.66:5060 ──────────┬──────────────────┬───────── ──────────┬───────── │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ INVITE (SDP) │ │ │ ──────────────────────────> │ │ │ 100 Trying │ │ │ <────────────────────────── │ │ │ 183 Session Progress (SDP) │ │ │ <────────────────────────── │ │ │ PRACK │ │ │ ──────────────────────────> │ │ │ 200 OK │ │ │ <────────────────────────── │ │ │ UPDATE (SDP) │ UPDATE (SDP) │ │ <─────────────────────────── │ │ ``` Whereas the expected behaviour should be: ``` │ │ UPDATE (SDP) │ | <────────────────────────── │ UPDATE (SDP)│ │ │ <───────── │ │ │ ``` This is also exemplified by examining the Via headers as rewritten by kamailio. Not working (>= 5.6.5, 5.7.x): * Inbound Via: `Via: SIP/2.0/UDP 195.167.21.66:5060;branch=z9hG4bKtjlwcpvfh03epe0thhtjhq3qg;Role=3;Hpt=8e58_16` * Oubound Via: `Via: SIP/2.0/UDP 185.73.43.241;branch=z9hG4bK66c4.3453dd9a219858819d528b9da671e39e.0` Working (5.6.4): * Inbound Via: `Via: SIP/2.0/UDP 195.167.21.66:5060;branch=z9hG4bK8lj1ahz6npz65khd8jkzl1ohh;Role=3;Hpt=8e68_16` * Oubound Via: `Via: SIP/2.0/UDP 172.30.154.1;branch=z9hG4bK4dce.4f5448efd64465fa5dbaf5eef0dc35b7.0` ### Possible Solutions Only solution I have found so far is to downgrade to kamailio 5.6.4  ### Additional Information ``` version: kamailio 5.7.4 (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_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 ``` But I have also tested all 5.7.x versions, which are all affected, as well 5.6.5. * **Operating System**:  ``` Linux host 5.10.0-27-amd64 #1 SMP Debian 5.10.205-2 (2023-12-31) x86_64 GNU/Linux ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3757 You are receiving this because you are subscribed to this thread.
