Hello again,

I've updated Kamailio to 5.7.5, set tls_threads_mode=2 and got another segfault:

And yes, the problem is definitely related to FIPS, because I did not see any errors with regular OpenSSL 3.x.

Hello Henning,

yes, I use this major version

$ openssl version
OpenSSL 3.0.7 1 Nov 2022 (Library: OpenSSL 3.0.7 1 Nov 2022)

Thanks, I'll try updating Kamailio and report the results.

Hello,

 

are you on openssl 3.x by any chance? If yes, please upgrade to kamailio 5.7.5 or 5.8.1 and set tls_thread_mode=2 in the kamailio.cfg, as it fixes certain memory corruption issues on this openssl version.

If you are still getting crashes after the upgrade and setting, please let us know, it might be something related to the FIPS mode.

 

Cheers,

 

Henning

Environment:

Oracle Linux Server 9.3

Kamailio 5.7.3

yum list --installed | grep ssl

openssl.x86_64                        10:3.0.7-24.0.3.el9_fips                  @tools              

openssl-libs.x86_64                   10:3.0.7-24.0.3.el9_fips                  @tools

xmlsec1-openssl.x86_64                1.2.29-9.el9                              @AppStream

 

What can I do for further investigation?

 

Thanks
