MikeBishop approved this pull request. Seems fine. I might flip around the statements to put the two that are logically similar together, though. You can error out if you receive: - The same sequence number with different values (CID or SRT) - A repeated CID (new sequence number) For the latter, though, it seems like a more conservative approach would be to retire it immediately without using it. Unless you're keeping a full history of CIDs for the life of the connection, you're probably not 100% certain it's a repeat, just that there was a hash collision and a repeat *might* have occurred. -- You are receiving this because you are subscribed to this thread.
