  "message": "Add initial state machine rewrite code\n\nThis is the first drop of the new state machine code.\n\nThe rewrite has the following objectives:\n- Remove duplication of state code between client and server\n- Remove duplication of state code between TLS and DTLS\n- Simplify transitions and bring the logic together in a single location\n  so that it is easier to validate\n- Remove duplication of code between each of the message handling functions\n- Receive a message first and then work out whether that is a valid\n  transition - not the other way around (the other way causes lots of issues\n  where we are expecting one type of message next but actually get something\n  else)\n- Separate message flow state from handshake state (in order to better\n  understand each)\n  - message flow state \u003d when to flush buffers; handling restarts in the\n    event of NBIO events; handling the common flow of steps for reading a\n    message and the common flow of steps for writing a message etc\n  - handshake state \u003d what handshake message are we working on now\n- Control complexity: only the state machine can change state: keep all\n  the state changes local to a file\n\nThis builds on previous state machine related work:\n- Surface CCS processing in the state machine\n- Version negotiation rewrite\n\nReviewed-by: Tim Hudson \u003ctjh@openssl.org\u003e\nReviewed-by: Richard Levitte \u003clevitte@openssl.org\u003e\n",
