I discussed with Rafa and found some issue on error message processing. The current specification specifies the rule on error message processing, but it is not clear what is the right protocol behavior after processing an error message. The erroneous request/answer transaction will be terminated after a protected error message exchange. But what is the next behavior? Repeating the erroneous request/answer transaction until session times out is obviously not a good approach. I think that a simple behavior is to silently terminate the PANA session immediately after any protected error message exchange.
Note that if an error message is non-protected, the following rule described in Section 5.8 still applies: If an error request or answer message is sent unprotected (i.e., without using an AUTH AVP) then the message MUST be processed such that the receiver does not change its PANA protocol state.
