Hi draft authors, Chris, Can we also please try and close on this issue raised by Chris. Chris, I don’t think that there is any great way to solve this issue using YANG features, but presumably the constraint could be enforced with a must statement, or groupings could be used to copy parts of t

[IPsec] Cookie logic results in failed authentication

2020-09-22 Thread Valery Smyslov
Hi, while performing stress tests, we ran into the problem, that is concerned with the way cookies are handled in RFC7296. The problem is that if network conditions are bad (high probability for packets to be delayed, reordered or lost), then some SAs are not established with AUTHENTICATION_FAIL

Hi Valery, It seems like a rare scene but I think it needs to be considered. Compared with ignoring cookie payload, how about adding N(COOKIE2) in the 9th message? Then when Initiator received the 12th message, it'll know which cookie this message matches with. Regards & Thanks! Wei Pan >

Hi Rafa, Thanks for getting back to me. Yes, changing the name of the module is an okay, if not ideal, resolution. But I appreciate that you also want to be done with this work. But I would like to check: My understanding is that the changes that Chris is proposing are pretty small. I.e. mo

Hi Tero, Thank you very much for your clarification. We will update reference RFC 822 accordingly in our draft. Tom, you proposed us to replace RFC 822 with 2822, but it is also obsoleted by 5322. So, if you agree, we will reference RFC 5322 instead. Best regards, Fernando. El mar., 22 sept. 2
