Hi Daniel, Which apt repository can we get this workaround? Today I noticed our Kamailio 5.2.4 cored during one of our load test sessions:

and I was wondering if this core is related.
Thanks

Hi Daniel,
Thanks a lot for this work; it's definitely important that Kamailio build against OpenSSL v1.1, and I'll be happy to contribute some testing in a live environment in the coming weeks. Much appreciated.
Have a good weekend,

Hello, after couple of months waiting for feedback about the workaround with the preloaded shared library to set the PTHREAD_PROCESS_SHARED attribute for pthread mutex/rwlock in order to avoid deadlocks and as it seems to be
the
solution, I just pushed a few commits to move that code in the core of kamailio.
It this way the initialization with the PTHREAD_PROCESS_SHARED attribute
is
done by default when libssl v1.1 is detected at compile time, without the need of using the approach with a preloaded library.
The shared library is still kept in the tls module:
https://github.com/kamailio/kamailio/tree/master/src/modules/tls/utils/opens...
Probably is going to be removed in the near future.
I am asking the community members that use Kamailio on systems with
libssl
v1.1+ to test the master branch and give feedback. The master branch is anyhow in testing phase for preparing the next major release v5.3.0, so
it
will help for that as well.
If no issue is going to be reported soon, the commits will be backported
to
stable branches, to re-enable smooth use of Kamailio with libssl v1.1+.
When libssl v1.1+ is detected, the core links with pthread, but that was already present in the Makefiles.defs for different compile options. The pthread more or less a default library on linuxes/unixes, so this should not introduce any major dependency to the Kamailio core.
Cheers, Daniel
