If confirmed, this one is critical, because it forbids the use of Rudder on centos 6 which is still widelly used.
We got more information by gitter: https://gitter.im/normation/rudder?at=5bc9ad3a435c2a518ecf1193
So, we need to reproduce ASAP:
- server debian 9: OpenSSL 1.1.0f
- client centos 6 : OpenSSL openssl-1.0.1e-57.el6.x86_64
And depending of the result, we may need to embed openssl for centos 6.

We were able to reproduce. There is something strange in the debian 9 (and perhaps ubuntu 18.04) cfengine binary. It seems to be linked to both OpenSSL 1.0 and 1.1. But that does not explains why exactly "debian x to debian 9" works but not "centos 6 to debian 9" does not.
We are working on the analysis of pairs that doesn't not work.
It may be the same root cause as #13766 where the server is ubuntu 18.04 / openssl 1.1, and the agent are in ubuntu 18.04 / openssl 1.0.

A server Rudder 5.0 on Debian9 with an Agent Centos 6 (5.0 ot 4.3) fails

Some more pair tested: on a Rudder 5.0, ubuntu 18.04:
- centos 7.5, debian 8.9, debian 9.5, ubuntu 18.04: OK
- centos 6.9: not ok.

Updated by François ARMAND about 6 years ago
Putting back relevant information from #13766:
- the bug is in OpenSSL certificat serialisation format incompatibility between openssl 1.0 and openssl 1.1.0. OpenSSL was producing not strictly exact certificate serialization which are now rejected.
- it is tracked on openssl: https://github.com/openssl/openssl/issues/7134
- it will be corrected in openssl 1.1.1: https://github.com/openssl/openssl/commit/ca89174bc92c16f0a2a7eb86359b6c6fd1dd7a4d
- other projects have the same problem, for ex: https://monitoring-portal.org/woltlab/index.php?thread/41664-ca-crt-verification-error-with-openssl-1-1-0-illegal-zero-content-in-field-seria/
For Rudder, it means that:
- Agent with openssl 1.0 can't connect to Rudder root server with openssl 1.1.0 (resp agent with openssl 1.1.0 can't connect to root server with openssl 1.0).
- openssl 1.1.0 is used in Rudder 5.0 on ubuntu 18_04, debian 9, and SLES 15
- so you can't mix these versions for root server with any other agent version (included agents on ubuntu 18_04/debian 9/SLES 15 on rudder 4.3 or older), nor you can use agent on these version with an server on any other os/rudder version.
As no distribs will be packaging openssl 1.1.1 until a long time, we can't rely on the distribution support.
If we choose to go for an homogeneous version of openssl, it can only be 1.0 (sinve we support os for agent which don't have 1.1.0 at all), but that means that for ex rudder server 5.0.1 on ubuntu 18_04 won't be able to discuss with rudder agent 5.0.with-the-correction on ubuntu 18_04. This is not possible.
So, the only path forward is to statically compile rudder with openssl 1.1.1 on ubuntu 18_04, debian 9 and SLES 15, for both agent and server.

- Description updated (diff)
In comment 20 above (https://issues.rudder.io/issues/13690#note-20), we though we had a solution for everything, but it wasn't sufficient because 1.0.1 is still not compatible with 1.1.1.
So we ended up embeding OpenSSL everywhere, with:
- version 1.0.2 for very old distros (AIX 5, Centos 3, centos 5..)
- version 1.1.1 everywhere.
It still means that people with agent relying on a OpenSSL 1.0.1.
It works correctly with openssl 1.1.0.
