[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] app_python3: make compatible with TLS refactoring (Issue #3832)
by space88man 29 Apr '24

29 Apr '24

### Description app_python3 loads libssl and also calls `pthread_setspecific()`. This makes it incompatible with tls_thread_mode refactoring. Reported by user @igorolhovskiy on the mailing list: https://lists.kamailio.org/mailman3/hyperkitty/list/sr-users@lists.kamailio… ### Troubleshooting #### Reproduction #### Debugging Data #### Log Messages #### SIP Traffic ### Possible Solutions - make it compatible with `tls_threads_mode = 1` ### Additional Information -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3832 You are receiving this because you are subscribed to this thread.

But internally for all save() calls the exact same function is use, w_save(). When calling save("PRE_REG_SAR_REPLY","location"); as given by the examples, kamailio will call w_save(). Because the command code will cast the function pointer, the w_save() function is called with 2 uninitialized arguments *mode, *c_flags. mode is unused, seems a legacy argument. c_flags is referenced resulting in a crash if not null. Use separate wrapper functions to handle different argument number.
