Subject [jira] [Created] (MESOS-6802) SSL socket can lose bytes in the case of EOF

--------------------------------

             Summary: SSL socket can lose bytes in the case of EOF
                 Key: MESOS-6802
                 URL: https://issues.apache.org/jira/browse/MESOS-6802
             Project: Mesos
          Issue Type: Bug
          Components: libprocess
            Reporter: Greg Mann


During recent work on SSL-enabled tests in libprocess (MESOS-5966), we discovered a bug in
{{LibeventSSLSocketImpl}}, wherein the socket can either fail to receive an EOF, or lose data
when an EOF is received.

The {{LibeventSSLSocketImpl::event_callback(short events)}} method immediately sets any pending
{{RecvRequest}}'s promise to zero upon receipt of an EOF. However, at the time the promise
is set, there may actually be data waiting to be read by libevent. Upon receipt of an EOF,
we should attempt to read the socket's bufferevent first to ensure that we aren't losing any
data previously received by the socket.
