Subject [jira] Created: (DIRMINA-85) SSLFilter race condition
Date Thu, 01 Sep 2005 11:47:05 GMT
SSLFilter race condition

         Key: DIRMINA-85
     Project: Directory MINA
        Type: Bug
    Versions: 0.9    
 Environment: Java 5, FC3 x86-64
 Reporter: Vinod Panicker
 Assigned to: Trustin Lee 
    Priority: Blocker

I'm facing a race condition in SSLFilter.  Basically I've done a "STARTTLS" kind of implementation
in which SSL is enabled over an existing plain-text connection.  The server tells the client
to start the SSL negotiation via the application protocol and puts an SSLFilter over the connection
to handle the handshake.

The race condition occurs when the client sends the SSL handshake even before the SSLFilter
is implemented on the connection.  This data is sent to the IoHandler and causes all sorts
of problems.  Ultimately the session is in limbo - it has to be closed.

A solution would be to stall the processing of incoming/outgoing data on the session till
the filter is implemented successfully.
