"Just" noise is a bit reductive. I recommend reading the paper/code. There's a lot of thought put into the higher levels of the protocol to make it an excellent VPN protocol, and not just a secure socket. Regarding building on 4.2.0; you should make sure it's a real 4.2.0 and not your distro's 4.2.0. I was shocked to see how many non-stability, non-security patches are backported by distro kernels. The package could say 4.2.0, but since 4.2 was never an upstream LTS release, it's likely that it's a frankenkernel. Because distro kernels often misrepresent the version, it seems like a real pain to keep DKMS working on them.
