Releasing v5.3.6
by Daniel-Constantin Mierla 10 Sep '20

10 Sep '20

Hello, I am considering to release v5.3.6 from the branch 5.3 in the next days, aiming from Thursday (Sep 10, 2020) if everything goes as planned at this moment, or on Monday (Sep 14, 2020) if a little bit of time is needed. Should you be aware of any issue that needs to be addressed in the branch 5.3 (e.g., a bug, or a missing backport), inform us as soon as possible to try to sort it out in time. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Funding: https://www.paypal.me/dcmierla

[kamailio/kamailio] Segmentation fault in rpc_mod_print function while shutting down server. (#2433)
by Andrey Deykunov 09 Sep '20

09 Sep '20

### Description We have segfault in Kamailio v5.3.1 installed on Debain 9.x 64 bit occured while kamailio was shutting down while our script tryed to get metric using kamcmd utility at the same time. ### Troubleshooting No troubleshooting was done, since it happened on a production server. We simply restarted the server. #### Reproduction The problem periodically happens on production servers during restart. Kamailio crashes when one of our scripts tried getting statistics about websocket and tls modules using kamcmd during server restart. As I see in core dump, shared memory was already freed when rpc_mod_print called in the child process. #### Debugging Data  ``` core.kamailio.17684 /var/lib/ums/sbin/kamailio GNU gdb (Debian 7.12-6) 7.12.0.20161007-git Copyright (C) 2016 Free Software Foundation, Inc.
