[Emu] TEAP Errata 5768

2019-10-07 Thread Joseph Salowey
We need to come to resolution on how to resolve these errata.  I hope there
has been enough time for implementors to catch up with
Jouni's implementation.

The Crypto-Binding TLV is fixed at 20 octets and the draft does not say how
to handle longer MACs.

The discussion seems to indicate that we should make the TLV variable
length to handle longer MACs.

Is anyone else taking this approach with their implementation?

Is there any objection to move forward with making the MAC variable
length?

Cheers,

Joe

  Given Jouni's experience with implementing TEAP, that may be best.

  i.e. TEAP cannot be implemented as-is.  The spec needs to be updated so that 
we can create inter-operable versions.

If we evolve draft-lear-eap-teap-brski into a more generic TEAP update we could 
cover TLS 1.3 there.

  I agree.

  My one worry is that if we update EAP-TLS without also updating PEAP and 
TTLS, then bad things will happen.

  My $0.02 is to remove the discussion of FAST and TEAP from 
draft-dekok-emu-tls-eap-types, as the remaining items are not controversial.  
The document should then be published simultaneously with the EAP-TLS updates.
