[kamailio/kamailio] Dialog: Timeout/dlg_bye randomly doesn't send BYE message (Issue #4169)
by Mercury109 23 Sep '25

23 Sep '25

Mercury109 created an issue (kamailio/kamailio#4169) ### Description I loop through the active dialogs in a timer functions and based on some conditions, a dialog may be ended by setting a short timeout or using the dlg_bye function. **Sometimes** when a dialog times out or the dlg_bye("all") function is used, the BYE is not being sent in both directions, only towards the caller. There's a warning: send_bye(): dlg [25641:71143] with callid XXXXXXXXX already in deleted state, BYE not sent. I noticed this check was added in the commit below: https://github.com/kamailio/kamailio/commit/d411c6ea4358e6d9dd367349e877ed5… Is there a race condition between marking the dialog as terminated and sending the BYE? Not sending a BYE towards the callee when it should is much worse than sending an unnecessary BYE as it causes billing issues. If this can't be resolved to be 100% reliable, it's safer to remove this check all together. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.7.6 (x86_64/linux)) ``` * **Operating System**: Debian GNU/Linux 12 (bookworm) -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4169 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] ims_isc: bugfix: firstflag incorrect in isc_match_filter (PR #4018)
by Kilian Wöber 21 Aug '25

21 Aug '25

#### Pre-Submission Checklist    - [x] Commit message has the format required by CONTRIBUTING guide - [x] Commits are split per component (core, individual modules, libs, utils, ...) - [x] Each component has a single commit (if not, squash them into one commit) - [x] No commits to README files for modules (changes must be done to docbook files in `doc/` subfolder, the README file is autogenerated) #### Type Of Change - [x] Small bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds new functionality) - [ ] Breaking change (fix or feature that would change existing functionality) #### Checklist:  - [ ] PR should be backported to stable branches - [x] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description  The function isc_match_filter uses a local variable "firstflag", to handle the case of an HSS based terminating unregistered service. In that case, the S-CSCF exchanges SAR/SAA with the HSS in order to learn the subscription data and the iFC for an unregistered user or for a PSI. The firstflag is necessary to make a distiction between the FAILURE ROUTE that is used for this case and the FAILURE ROUTE that is used for transaction failure towards the AS. The error is, the firstflag is set for the latter case, too, which leads to a wrong handling of communication errors towards the AS. This PR introduces a new function that looks for the old ISCMARK in the lumps of the stored message and hence can make a distinction between the SAR/SAA case and the AS failure case.

by QuincyGao 21 Jul '25

21 Jul '25

QuincyGao created an issue (kamailio/kamailio#4189)  ### Description  I used dmq on two machines, registered two softphones on the 111 machine, and then used one phone to call another.

[kamailio/kamailio] siptrace: sip_trace_mode("d") not working (Issue #4178)
by c.long 18 Jul '25

18 Jul '25

longchun4835 created an issue (kamailio/kamailio#4178)  ### Description Using function sip_trace_mode() with parameter d to enable dialog tracing mode logs: ``` BUG: siptrace [siptrace.c:1671]: add_info_xavp(): URI should be in raw format here ERROR: siptrace [siptrace.c:888]: sip_trace_helper(): failed to serialize siptrace info! Won't trace dialog! ``` ### Troubleshooting #### Reproduction my module parameters: ``` #!ifdef WITH_HOMER loadmodule "siptrace.so" modparam("siptrace", "duplicate_uri", HOMER_URL) modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_flag", 22) modparam("siptrace", "trace_on", 1) modparam("siptrace", "hep_version", 3) modparam("siptrace", "hep_capture_id", HOMER_HEP_ID) #!endif ... request_route { ... if (is_method("INVITE")) { sip_trace_mode("d"); } } ``` ### Possible Solutions I checked the source code and found that the issue occurs when sip_trace_helper() is called inside the ki_sip_trace_mode() function, with the third parameter (duri) set to NULL. I don’t quite understand the logic behind passing NULL does this mean that the 'D' parameter will never working when calling sip_trace_mode()? Additionally, I have another question: in the sip_trace_helper() function, why does it call trace_transaction() instead of trace_dialog() when strace_type == SIPTRACE_DIALOG? ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.6.4 (x86_64/linux) a004cf flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, 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 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: a004cf compiled on 09:14:30 Jan 23 2025 with gcc 8.3.1 ``` * **Operating System**: ``` NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4178 You are receiving this because you are subscribed to this thread.

Kamailio rpm server
by Patrick Wakano 08 Jul '25

08 Jul '25

Hello list, Hope everyone is fine. I'm trying to install the latest 6.0.1 version from https://rpm.kamailio.org/centos/ but it doesn't seem to be updated...The latest version available there is the 5.8.5. Version 6.0.0 isn't there as well... Is it still maintained? or just some rpmbuild command missed? Thank you, Patrick

[kamailio/kamailio] Kamailio blocks in SSL_accept (Issue #4185)
by Mathias Schneuwly 04 Jul '25

04 Jul '25

schneuwlym created an issue (kamailio/kamailio#4185) ### Description This issue is a follow up of the discussion in the [mailing list](https://lists.kamailio.org/mailman3/hyperkitty/list/sr-users@lists.ka… We are using Kamailio 5.8.4 in a yocto scarthgap based image. We noticed on multiple nodes, that suddenly phones lost their registrations and the log showed messages like `send_fd(): sendmsg failed sending 55 on 52: Too many references: cannot splice (109)`. After debugging we guess that the `send_fd` messages are just a symptom, not the cause. Generating a backtrace using `kamctl trap` shows that all TCP receiver are waiting for a `pthread_rwlock_...` lock. Our deployments, where we randomly see the issue, are very small; 10-30 registrations. I've tested kamailio version 5.8.4, 5.8.5, 5.8.6 and 6.0.1 and I was able to reproduce the issue with all versions. I've also tested version 5.5.4, but with an older yocto (dunfell) which used openssl 1.1.1w, **which did not block!** Yocto Scarthgap uses OpenSSL 3.2.3 and we also updated to version 3.4.1, which didn't show any difference. ### Troubleshooting #### Reproduction Meanwhile we found a way to reproduce the issue within seconds. It requires a bit of brute force, but it locks kamailio reliable. We are generating 3 parallel SIP REGISTER streams with sipexer to 3 different accounts. Following an example of one stream: ``` watch -n 0.1 "./sipexer -register -vl 3 -co -com -ex 3600 -fu "2" -au "2" -ap "test" -tk <path to key>.key -tc <path to certificate>.cer -ti -sd -ru sip:<domain> -cu sip:2@<domain> tls:<fqdn>:5061;sleep 0.1;./sipexer -register -vl 3 -co -com -ex 0 -fu "2" -au "2" -ap "test" -tk <path to key>.key -tc <path to cert>.cer -ti -sd -ru sip:<domain> -cu sip:2@<domain> tls:<fqdn>:5061" ``` Our dialplan is quite complex, but I was also able to reproduce the issue with the default [dialplan](https://raw.githubusercontent.com/kamailio/kamailio/refs/heads/5.… with the following changes: ``` 169a170,171 > #!define WITH_TLS > 205a208,219 > alias=udp:<domain>:5060 > alias=udp:127.0.0.1:5060 > alias=udp:10.0.6.1:5060 > alias=tls:<domain> > alias=tls:10.0.6.1:5061 > alias=tls:10.165.42.76:5061 > alias=tls:<domain>:5061 > alias=udp:<domain> > listen=udp:127.0.0.1:5060 > listen=tls:10.0.6.1:5061 > listen=udp:10.0.6.1:5060 > listen=tls:10.165.42.76:5061 498c512 < modparam("tls", "config", "/usr/local/etc/kamailio/tls.cfg") --- > modparam("tls", "config", "/etc/kamailio/kamailio-tls.cfg") ``` ``` # cat /etc/kamailio/kamailio-tls.cfg [server:default] method = TLSv1+ verify_certificate = yes require_certificate = yes private_key = "<path to key>.key" certificate = "<path to cert>.crt" ca_list = "<path to ca>.pem" [client:default] method = TLSv1+ verify_certificate = yes require_certificate = yes private_key = "<path to key>.key" certificate = "<path to cert>.crt" ca_list = "<path to ca>.pem" ``` #### Debugging Data Following the backtrace of one tcp listener process.

[kamailio/kamailio] [Websocket] websocket:closed sometimes is not fired (Issue #3950)
by Gustavo Almeida 27 Jun '25

27 Jun '25

### Description After carrying out some load tests using the `Websocket` module, I noticed that sometimes the `websocket:closed` event is not triggered. This problem seems to be particularly noticeable when the load is high and simultaneous. Example: 1000 records simultaneously. In the tests carried out, I realized that the number of times the event is not triggered is small, in the order of [1-10]/1000. I check that when I do a `ws.dump` I don't have any active connections, and I confirm that they are all effectively cleaned (`netstat -ano | grep 8061`). However, the event is not triggered for some connections. I can see this in the logs, and also when i display the content of an hash table, i'm dropping key inside `websocket:closed` event. ### Troubleshooting The troubleshooting was simplistic, i.e. I ran the same test n times, and validated that the event was triggered for all connections, the number of `ws` connections listed by `Kamailio`, and the open connections. #### Reproduction To reproduce, we can use any mechanism that emulates the use of the `Websocket` module. For example, I used the `sipexer` tool to create a `wss` connection with `Kamailio`, forcing simultaneous registrations. Example command: `sipexer -cb -mt register -ex 60 -au <user> -ap <pass> -fuser example -fd mydomain -wso https://10.0.0.12:10000 -ruri sip:kamailio -su wss://kamailio:8061` Kamailio TLS listener: `listen=tls:10.0.0.12:8061 advertise PUBLIC_IP` Websocket module: ``` loadmodule "websocket.so" tcp_accept_no_cl=yes ``` ``` event_route[websocket:closed] { xlog("L_NOTICE", "WebSocket connection closed $proto:$si:$sp\n"); <I also delete where a htable key> } ``` #### Debugging Data ``` [root@ ~]$ prcmd ws.dump { connections: { } info: { wscounter: 0 truncated: no } } [root@ ~]$ netstat -ano | grep 8061 tcp 0 0 10.0.0.12:8061 0.0.0.0:* LISTEN off (0.00/0/0) [root ~]$ prcmd htable.dump wsauth | grep "name" | wc -l 3 [root ~]$ cat /var/log/kamailio.log | grep "WebSocket connection closed" | wc -l 997 [root ~]$ cat /var/log/proxy-registrar/proxy-registrar.log | grep "ERR" | grep "WAR" | wc -l 0 ``` #### Log Messages Nothing relevant. #### SIP Traffic Nothing relevant here, the SIP Flow is OK. ### Additional Information ``` version: kamailio 5.6.4 (x86_64/linux) a004cf-dirty flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, 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 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: a004cf -dirty compiled on 23:17:27 Jun 7 2024 with gcc 4.8.5 ``` * **Operating System**: ``` CentOS Linux release 7.9.2009 (Core) ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3950 You are receiving this because you are subscribed to this thread.
