[kamailio/kamailio] a single digit is a valid enum_query() request (#593)
by Jonas 05 Aug '26

05 Aug '26

We use enum_query() to dispatch calls over a set of gateways. In our case single digits (for instance "8") can be a valid direct dial number which we would like to through against our enum server. Is there any good reason to limit the request to 2 digits as minimum?

[kamailio/kamailio] Add Username support for authentication in redis and sentinel w.r.t NDB REDIS (Issue #3552)
by hemanth-vulavala 27 Jul '26

27 Jul '26

### Description The current issue revolves around the absence of username support within the NDB REDIS KAMALIO framework when dealing with Redis, particularly concerning the Redis and Sentinel components. While Redis inherently offers the capability to utilize both usernames and passwords during authentication, this capability is not currently extended to the NDB REDIS KAMALIO setup. As a result, when attempting to establish connections to Redis instances through NDB REDIS KAMALIO, there is no provision for providing a username as part of the authentication process. Instead, the framework only accommodates the usage of passwords for authentication. This stands in contrast to Redis, which permits the inclusion of both usernames and passwords for enhanced security measures. Consequently, the limitation within NDB REDIS KAMALIO can hinder organizations seeking to ensure comprehensive security practices, especially when the requirement is to employ both usernames and passwords for authentication. This divergence between the authentication capabilities of Redis and NDB REDIS KAMALIO can potentially compromise security standards and hinder compatibility with certain authentication setups. To address this issue, it would be essential for the development team behind NDB REDIS KAMALIO to enhance the framework's capabilities by incorporating support for username-based authentication in addition to passwords. This alignment with Redis's authentication model would ensure that organizations can confidently implement secure data interactions while maintaining consistency with established security policies  ### Expected behavior The expected behavior entails an improvement within the NDB REDIS KAMALIO framework to support both usernames and passwords for authentication when interacting with Redis instances, particularly in the Redis and Sentinel components. This enhancement would bring NDB REDIS KAMALIO in line with Redis's native authentication capabilities, where both usernames and passwords are accepted during the authentication process. Upon implementing this improvement, users of NDB REDIS KAMALIO should be able to configure their connections by providing both a username and a password as part of the authentication details. This allows NDB REDIS KAMALIO to establish connections to Redis instances that require both authentication credentials, thereby enhancing security and ensuring compatibility with various authentication setups. By incorporating support for usernames in addition to passwords, NDB REDIS KAMALIO can accommodate organizations that require comprehensive security measures, especially in scenarios where username-based authentication is mandated. This alignment with Redis's authentication model would enable organizations to effectively collect, manage, and interact with data while adhering to established security policies. In summary, the expected behavior is that NDB REDIS KAMALIO should be upgraded to offer support for usernames and passwords during authentication, mirroring Redis's capabilities. This enhancement ensures a consistent and secure approach to data interactions and supports various authentication requirements within Redis environments #### Actual observed behavior The current actual behavior is that NDB REDIS KAMALIO does not have the capability to accept usernames as part of the authentication process when connecting to Redis instances, specifically in both the Redis and Sentinel components. While Redis itself allows for the usage of both usernames and passwords for authentication, this feature is not currently integrated into the NDB REDIS KAMALIO framework. As a result, when configuring connections to Redis instances using NDB REDIS KAMALIO, there is no provision to include a username alongside the authentication details. The framework only accommodates the use of passwords for authentication purposes. This deviation from Redis's authentication model could lead to compatibility issues with certain authentication setups, particularly those that mandate the use of both usernames and passwords. In essence, the actual behavior is that NDB REDIS KAMALIO falls short of aligning with Redis's authentication capabilities, thereby potentially hindering secure data interactions and limiting compatibility with certain security policies. Users attempting to adhere to comprehensive authentication practices may face challenges when utilizing NDB REDIS KAMALIO due to its inability to support usernames during authentication. To address this actual behavior, it would be necessary to enhance NDB REDIS KAMALIO's capabilities to include support for both usernames and passwords during the authentication process. This enhancement would ensure that organizations can confidently utilize NDB REDIS KAMALIO while maintaining the security standards and authentication requirements necessary for their Redis environments. #### Debugging Data ``` (paste your debugging data here) ``` #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  ### 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/3552 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] presence: preserve etag uniqueness when marking presentity for removal (PR #4275)
by Alessio Garzi 25 Jul '26

25 Jul '26

#### 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: - [x] PR should be backported to stable branches - [x] Tested changes locally - [ ] Related to issue #### Description When the `presence` module attempts to clean up records in the `presentity` table, it replaces the `etag` with a static, hardcoded string: ``` "*#-OFFLINE-#*" ``` However, the `presentity` table enforces a uniqueness constraint on the following combination of fields: ``` MariaDB [kamailio]> show create table presentity; | presentity | CREATE TABLE `presentity` ( ... UNIQUE KEY `presentity_idx` (`username`,`domain`,`event`,`etag`), ``` This approach breaks the uniqueness of etag, which is intended to differentiate records , especially in cases such as parallel calls, or when using kamailio as a forking proxy. Instead of overwriting the etag with the static offline marker, this patch appends the marker to the existing etag value. This ensures the offline flag is retained while preserving the uniqueness of the etag. The deletion query was also updated accordingly: it now identifies offline records using a LIKE '%*#-OFFLINE-#*' clause. Based on testing, the duplicate key errors no longer occur, and the cleanup logic now behaves as expected. This patch improves the reliability of presentity cleanup without requiring schema or index changes. Please consider merging into master. Thanks!

[kamailio/kamailio] Memory usage increases everytime tls.reload is executed (Issue #3823)
by Sebastian Denz 10 Jul '26

10 Jul '26

### 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] ims_diameter_server not freeing shared memory (Issue #4116)
by MGrimby 20 May '26

20 May '26

### Description I have run in to an issue when sending diameter requests using the ims_diameter_server module. Shared memory keeps increasing and are not being freed until restart of kamailio. This leads to all shared memory is being used and no more are able to be allocated. This only happens when the request is sent synchronously. When sent asynchronously shared memory is being freed as far as I can see. Following functions have been used for sending requests. diameter_request([peer], appid, commandcode, message) diameter_request_async([peer], appid, commandcode, message) ### Troubleshooting Sent a bunch of diameter requests and verified that shared memory for the following functions are not freed. do_receive(600): AAATranslateMessage(500): AAACreateAVP(137): #### Reproduction It's possible to reproduce by sending sync diameter request and verify shared memory.

[kamailio/kamailio] Issue with usrloc 'handle_lost_tcp' and dmq_usrloc 'usrloc_delete' (Issue #3479)
by alternatenetwork 02 May '26

02 May '26

### Description When a TLS connection is closed and handle_lost_tcp=1 the entry is deleted for usrloc. This deletion is not synced via DMQ even though usrloc_delete=1. There is also an issue on the same server if a re-registration happens right after before the timeout was supposed to expire then $var(sv_res) = 2 even though the usrloc table is empty. So it seems like the way handle_lost_tcp deletes is not deleting fully in registrar. usrloc db_mode is 0 ### Troubleshooting #### Reproduction Setup 2 servers with DMQ and close the TCP connection. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.6.1 (x86_64/linux) d8f98b 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, 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: d8f98b compiled on 19:05:04 Aug 16 2022 with gcc 8.3.0 ``` * **Operating System**:  ``` Debian 10 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3479 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Kamailio 5.4.x dialog profiles functionality dead-lock on certain high-load scenarios (Issue #2923)
by Henning Westerholt 03 Apr '26

03 Apr '26

### Description The Kamailio 5.4.x dialog profiles functionality can lead to dead-lock on certain high-load scenarios. The Kamailio dialog profiles are used to track parallel channels for about 200 outgoing PSTN carrier interconnections. During high traffic times (like several thousands parallel calls) the Kamailio server will frequently (e.g. hourly) goes into an end-less loop while executing get_profile_size in the configuration script. This causes the locking for the dialog profiles never be released and Kamailio will stop serving traffic. Internal monitoring tools and RPC commands stay working, as long as they do not touch the dialog functionality. A similar (dedicated) Kamailio setup is used for tracking parallel channels for customers. Here the dead-lock is not observed that frequently, but aparentely also some crashes happens in a much longer time interval. ### Troubleshooting After analysis of the back-traces with GDB the get_profile_size() function was removed from the configuration script. After this change the crash did not happened anymore for several days. #### Reproduction Issue could not be reproduced so far. #### Debugging Data ##### bt 1 (some data removed) (gdb) bt \# 0 0x00007f57cf3b00da in get_profile_size (profile=0x7f50ccbc7e80, value=0x7ffd9928f300) at dlg_profile.c:859 n = 364 i = 12 ph = 0x7f50d3e4b7d0 \# 1 0x00007f57cf419c67 in w_get_profile_size_helper (msg=0x7f57d699d418, profile=0x7f50ccbc7e80, value=0x7ffd9928f300, spd=0x7f57d6916960) at dialog.c:941 \# 2 0x00007f57cf41a459 in w_get_profile_size3 (msg=0x7f57d699d418, profile=0x7f50ccbc7e80, value=0x7f57d6935118, result=0x7f57d6916960) at dialog.c:982 \# 3 0x0000000000463fea in do_action (h=0x7ffd99293610, a=0x7f57d6936488, msg=0x7f57d699d418) at core/action.c:1094 \# 4 0x00000000004711ee in run_actions (h=0x7ffd99293610, a=0x7f57d6936488, msg=0x7f57d699d418) at core/action.c:1581 \# 5 0x000000000046058b in do_action (h=0x7ffd99293610, a=0x7f57d690fda8, msg=0x7f57d699d418) at core/action.c:700 The first back-trace was taking from a running process with gdb. The counter in f0 does not increased that much during this time, probably due the overflow of the loop counter. ##### bt2 (analysis with data structure with gdb scripts) Here the loop counter in f0 showed a really high value.
