We tried to backport the patch for OpenSSL-3.0 support (https://github.com/MariaDB/server/commit/c80991c79f701dac42c630af4bd39593b0c7efb4) to the MariaDB Server 10.5 version.
We know, this patch was not implemented on the 10.5 version, however, in the Centos-Stream-9 and RHEL-9, we are implementing the 10.5 version as the major version, and then we will add other versions in form of modules.
The biggest concern for us right now is the OpenSSL-3.0 support in version 10.5 and we want to provide all the helpful feedback we can, in order to achieve it.
The patch actually fixed all of the encryption.* and binlog_encryption.* tests, but as the other side of the coin, other tests started to fail.
I'm attaching the list of failed tests.
I can also provide the logs of the failing tests if that will help you, but it will be a lot bigger files, so first let me know if that will help you and I can attach them as well.
