When first connecting the client sends the max version number it supports & whether it supports clear mode & TLS mode. Server rejects clients with incompatible major, or picks maximum minor version supported by both client & server. If server requires TLS it will reject a client not advertising support of TLS mode. Upon completion of 'hello' request+reply, will do TLS handshake. If successfull, then server will enable the rest of the protocol messages, otherwise it drops the client. NB, there is bucket loads of printf() debugging in these patches since I was still experimenting with the TLS stuff. I simply removed -std=c99 and fixed up places I'd used C99 constructs, so should no longer be needed Not merged yet Now unneccessary Merged these two. Merged these two. When updating this you need two core changes: - Change all 'int' to one of int32_t, uint32_t, int64_t, uint64_t - Use 'qemud_wire_32' or 'qemud_wire_64' when reading or writing data to the qemud_packet members.
