[jira] [Created] (MESOS-10113) OpenSSLSocketImpl with 'support_downgrade' waits for incoming bytes before accepting new connection.

Benjamin Mahler created MESOS-10113:
---------------------------------------

             Summary: OpenSSLSocketImpl with 'support_downgrade' waits for incoming bytes before accepting new connection.
                 Key: MESOS-10113
                 URL: https://issues.apache.org/jira/browse/MESOS-10113
             Project: Mesos
          Issue Type: Bug
          Components: libprocess
            Reporter: Benjamin Mahler


The accept loop in OpenSSLSocketImpl in the case of {{support_downgrade}} enabled will wait for incoming bytes on the accepted socket before allowing another socket to be accepted. This will lead to significant throughput issues for accepting new connections (e.g. during a master failover), or may block entirely if a client doesn't send any data for whatever reason.

Marking as a bug due to the potential for blocking incoming connections.
