Regarding rejectClientInitializedRenego, I think the word "Initiated"
more succinctly captures the intent of this property, rather than
"Initalized." And as long as the word "Renegotiation" is, it should
probably be spelled out completely. AFAIK, we rarely abbreviate
external names like this.
Same "initiated" comment about the variable name in your codereview, but
I don't care much about Renogo.
283: My initial thought was a no_renegotiation(100) warning, but that
allows the client to decide what to do, rather than the server terminating.
This TLS logic decision is not straightforward, so this needs commenting.
379: since you're making changes here.
Since you already have CCC approval and are ready to putback, I would
suggest putting back now, and let's file another CCC to change the name.
That should be a no-brainer.
