[kamailio/kamailio] dispatcher: socket atribute usage for initial OPTIONS (#2853)

by sergey-safarov

### Description I use TCP sockets to relay calls to backend servers. Also, I have enabled `tcp_reuse_port` and enabled `socket` attribute in dispatcher settings. INVITE messages to backend servers are now properly send from port 5060. ### Expected behavior For all messages are used the same TCP socket and same source port for all messages (including OPTIONS). #### Actual observed behavior But initial OPTIONS (before the first call send) uses a random source port. ### Additional Information * **Kamailio Version** - output of `kamailio -v` used current c503d2bd31a580138a67f1d4a265ccde5791d271 with small customization. * **Operating System**: aarch64 ``` [root@sbc-a0 ~]# cat /etc/os-release NAME="CentOS Linux" VERSION="8" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="8" PLATFORM_ID="platform:el8" PRETTY_NAME="CentOS Linux 8" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:8" HOME_URL="https://centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-8" CENTOS_MANTISBT_PROJECT_VERSION="8" ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] [stirshaken] add identity header in reply messages or to a separate variable (#2770)

by sergei lavrov

### Description I'm unable to add the generated `Identity` value to reply message when `kamailio` acts as a redirect server and replies with `302 Moved Temporarily` instead of relaying `INVITE`. This code doesn't work, i.e. no `Identity` header in `302 Moved Temporarily` message: ``` if (stirshaken_add_identity($var(x5u), $var(attest), $var(origtn_val), $var(desttn_val), $var(origid)) == 1) { append_branch("sip:$rU@127.0.0.1:6060"); sl_send_reply("302", "Moved Temporarily"); exit; } ``` ### Expected behavior It would be nice if the `stirshaken_add_identity_*` functions would add the generated `Identity` header to the reply messages too, or store the generated `Identity` header in a separate variable, like `$identity`, for the future processing. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] kamctl - maintenance for dbtextdb.py tool (#2469)

by Daniel-Constantin Mierla

**kamctl** include a python tool that is parsing SQL statements to do operations over the **db_text** files, for the common db operations (e.g., insert, delete). It is located at: * https://github.com/kamailio/kamailio/tree/master/utils/kamctl/dbtextdb The tool was contributed long time ago and not kept up to date, being known not to work with Python3 (e.g., #2464). This issue is created to see if someone has the interest to pick up the maintenance of this tool, if not it will be removed from kamctl. Note that db_text works with text files, so it is not necessary to have a tool for managing the content of these files, they can be simply updated with any text editor. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] [kamctl] Dispatcher operations in a case of db_text are mostly incorrect (#2464)

[kamailio/kamailio] [Feature Request] Add reload capability for geoip2 module (#2029)

by Joel Serrano

### Description Currently, the `geoip2` module loads the IP database at startup and keeps it in cache and there is no way to tell Kamailio to reload the database without a full restart. ### Possible Solutions To keep this module inline with other modules that use external datasources, I would suggest to implement a new RPC command and a new geoip2 function to reload the database defined in the `path` geoip2 modparam without the need of a restart. I'm not aware of the effort required for implementing either of them, but only having an RPC command would effectively solve this issue as you can call RPC commands from within Kamailio conf, thus, the reload function would not be something strictly required but more of a nice-to-have. ### Examples: Function: ``` geoip2_reload() ``` RPC command: ``` kamctl rpc gip2.reload / kamctl rpc geoip2.reload ``` Kamcmd command: ``` kamcmd geoip2.reload ``` -- 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

### 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.
