[jira] [Commented] (MESOS-9730) Executors cannot reconnect with agents using TLS1.3

    [ https://issues.apache.org/jira/browse/MESOS-9730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16818147#comment-16818147 ] 

Till Toenshoff commented on MESOS-9730:
---------------------------------------

It appears this problem is not newly introduced or a regression codebase - instead something we did never properly support. Deprioritizing this to unblock the upcoming release. We need to come up with a plan here for proper OpenSSL 1.1 support; possibly following [~kaalh]'s reasonable suggestions.

>             Project: Mesos
>          Issue Type: Bug
>          Components: libprocess
>    Affects Versions: 1.8.0

> TLS 1.3 support is enabled by default from openssl >= 1.1.0
> Executors do not reconnect with agents after restart when using TLS 1.3, and I guess this should also affect master/slave communication.
> suggested action :
> add a `LIBPROCESS_SSL_ENABLE_TLS_V1_3` environment variable with a `false` default, and apply `SSL_OP_NO_TLSv1_3` ssl option when building with openssl >= 1.1.0
