Hi,
this is just an example showing the happy path of interaction. Generally for me it sounds reasonable what you are saying and I will be happy to merge a PR if you provide one with this fix.
I understand your view on the samples/
directory, but I think that this behavior traces back to the src/edhoc/initiator.c
file. Specifically this rx call is not present in the default case (without EDHOC Message 4 support) so the response to EDHOC Message 3 is not received.
Some Questions:
The spec is very clear on this. See EDHOC Message 4.
yes
Again the example is showing only a happy path with 3 messages. In this case the application needs to continue with an OSCORE message.
Hello,
We are developing a model learning tool for EDHOC clients and servers and we have used the implementations found in
samples/linux_edhoc
andsamples/linux_edhoc_oscore
, in order to learn their models and analyze their behavior.Regarding the
samples/linux_edhoc/initiator
of the main branch's commit fbaa96caa1a2028d369c70e24a173caa60a0ce15 we observed the following behavior:The client initiator sends the EDHOC Message 1, receives the EDHOC Message 2 and then sends the final EDHOC Message 3. Interestingly, the client does not wait for a response to the EDHOC Message 3 and terminates immediately.
Is it an issue or is this deliberate ? According to the RFC, shouldn't the client initiator wait for a response to the EDHOC Message 3, in case this response is an (EDHOC) error message ?
