Hi,

that is set when a session encounters EOF.

Subject: [PATCH] session: use unique EOF error message

Use a unique error message for the EOF case in the session socket exception
handler.  This changes the error string obtained with ssh_get_error from
"Socket error: Success" to the more helpful "Socket received EOF".
