Well, to be fair, we did eliminate the trip up to
userland and back down
and did the bulk crypto in the kernel... We did do the session
negotiation in userland though, but once that was done, the rest was done
in-line in the kernel...
Plan 9 has had the SSL record layer and bulk crypto
in the kernel for almost 25 years. Just sayin'. ☺
