[kamailio/kamailio] tm:local-request not documented (#980)
by Olle E. Johansson 18 Oct '23

18 Oct '23

The local-request event route is not documented. When using our friend google I find an old blog post by @miconda but not much else. I can come up with some good text, but need to know what can be done in the route, like - modify request uri - add/remove headers - drop request - add/modify destination uri ($du) -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] core: fixed wrong network interface selection. (PR #3490)
by Ivanuschak Nikolay 25 Sep '23

25 Sep '23

fixed incorrect source IP address selection for the SIP messages sending procedure when TCP transport is used or for UDP with the 'mhomed' setting set as 'mhomed=1'.   #### Pre-Submission Checklist    - [x] Commit message has the format required by CONTRIBUTING guide - [ ] Commits are split per component (core, individual modules, libs, utils, ...) - [ ] Each component has a single commit (if not, squash them into one commit) - [ ] 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 - [x] Related to issue #3486(replace XXXX with an open issue number) #### Description  The current service behavior is as follows: if OS contains several network interfaces and the service has a listening TCP socket (or UDP with 'mhomed=1' setting) on the second (third, fourth and so on) interface, then the outbound SIP messages will be always sent from the first (default) interface. These changes make the outbound SIP messages always going through the network_interface/address, which is taken for listening by service.

Re: Performances issue when freeing shared memory in custom module (Kamailio 5.5.2)
by Henning Westerholt 04 Aug '23

04 Aug '23

Hello, (Adding sr-dev to CC) This looks indeed a bit strange. Do you get any error messages in the log? In which process you are freeing the memory, one of the worker processes or the RPC process? You could also try to use another memory manager to see if you get better performance. There is a command line parameter to choose one during startup. Cheers, Henning -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://gilawa.com<https://gilawa.com/> From: Chaigneau, Nicolas <nicolas.chaigneau(a)capgemini.com> Sent: Wednesday, January 18, 2023 6:49 PM To: Kamailio (SER) - Users Mailing List <sr-users(a)lists.kamailio.org> Subject: [SR-Users] Performances issue when freeing shared memory in custom module (Kamailio 5.5.2) Hello, I'm encountering performance issues with Kamailio (5.5.2). I'm using a custom Kamailio module that loads routing data in memory, using Kamailio shared memory. This routing data is very large. It can be fully reloaded through a Kamailio RPC command (which is done once each day). When reloading, two sets of data are maintained, one "loading" and another "current" (the latter being used to handle SIP requests). When loading of the new data is finished, it is swapped to "current". Then, memory of the old (now unused) data is freed. I've noticed that when Kamailio is freeing the old data, there is a very significant performance impact on SIP requests. This is surprising to me, because the SIP requests do not use this old data. This is not a CPU issue, idle CPU% is at about 99% at that moment. I'm using the following functions : - shm_mallocxz - shm_free From what I understand, shm_free is actually "qm_shm_free" defined in "src\core\mem\q_malloc.c" (the default shared memory manager being "qm"). I've noticed that there is also a variant shm_free_unsafe ("qm_free"), which does not perform locking. I'm wondering if the lock could be the cause of my performances issues ? (But I'm not sure how this could be possible, because although the SIP requests need to access the shared memory allocated, they do not use directly the functions from the share memory manager.) If the performances issues are causes by the lock, could I use the unsafe version "safely" ? (considering that it is guaranteed that the old data cannot be used by anyone else) Thanks for your help.
