I think you have missed this security API in your patches.
Also I don't think this methodology for adding the private data in 
session will work in case of security sessions. As we have only one API 
for creating/configuring the security session. However, we can add a 
parameter in the rte_security_session_create(). Since this API is still 
experimental, we can change the parameters. What Say?
