Hi, I've been reading the RFC draft for the OpenSSH agent protocol and trying to understand the extension mechanism. It seems like a client, after sending an extension message, will have to then interpret any following success (0x6) message differently according to the extension request just sent. The example with the "query" extension returning a success message with extra data appended would seem to imply that, too. Is that correct? If so, I would love to get some insight into why this was chosen over having an "extension reply" message number or something like that. It seems to me that the protocol up until now has always been stateless -- you didn't have to know what you sent last in order to parse and validate received data -- which generally makes implementations nice and simple. After this change, client impls will have to change their parsing of the success message dramatically after sending each extension request message (and will have to track which ext they last sent etc), since it doesn't include enough information in the message itself any more to figure out what it should contain. Sorry if I'm retreading on a discussion that's already been had (I did search this list but couldn't find anything) Thanks! _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
