Move some function definitions around within the state machine to make sure they are in the correct files. Also create a statem_locl.h header for stuff entirely local to the state machine code and move various definitions into it.

Pull out the state machine into a separate sub directory. Also moved some functions which were nothing to do with the state machine but were in state machine files. Pulled all the SSL_METHOD definitions into one place...most of those files had very little left in them any more.

Previously each message specific process function would create its own PACKET structure. Rather than duplicate all of this code lots of times we should create it in the state machine itself. Reviewed-by: NTim Hudson <tjh@openssl.org> Reviewed-by: NRichard Levitte <levitte@openssl.org>

The SSL structure contained a "state" variable that kept track of the state machine in the old code. The new state machine does not use this so it can be removed. Reviewed-by: NTim Hudson <tjh@openssl.org> Reviewed-by: NRichard Levitte <levitte@openssl.org>

The SSL structure contained a "type" variable that was set to either SSL_ST_ACCEPT or SSL_ST_CONNECT depending on whether we are the server or the client. This duplicates the capability of the "server" variable and was actually rarely used. Reviewed-by: NTim Hudson <tjh@openssl.org> Reviewed-by: NRichard Levitte <levitte@openssl.org>

ssl.h and ssl3.h have a number of defines for the various states in the old state machine code. Since this is public API it is not desirable to just remove them. Instead redefine them to the closest equivalent state in the new state machine code. If an application calls SSL_state then the return value can still be compared against these old values if necessary. However not all values have an equivalent state in the new code, so these are just redefined to a dummy value.

The new state machine code will split up the reading and writing of hanshake messages into discrete phases. In order to facilitate that the existing "get" type functions will be split into two halves: one to get the message and one to process it. The "send" type functions will also have all work relating to constructing the message split out into a separate function just for that. For some functions there will also be separate pre and post "work" phases to prepare or update state. Reviewed-by: NTim Hudson <tjh@openssl.org> Reviewed-by: NRichard Levitte <levitte@openssl.org>

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

The function ssl3_get_message gets a whole message from the underlying bio and returns it to the state machine code. The new state machine code will split this into two discrete steps: get the message header and get the message body. This commit splits the existing function into these two sub steps to facilitate the state machine implementation.

Move all packet parsing to the beginning of the method. This limits the SSLv2 compatibility soup to the parsing, and makes the rest of the processing uniform. This is also needed for simpler EMS support: EMS servers need to do an early scan for EMS to make resumption decisions. This'll be easier when the entire ClientHello is parsed in the beginning. As a side effect, 1) PACKETize ssl_get_prev_session and tls1_process_ticket; and 2) Delete dead code for SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG. Reviewed-by: NMatt Caswell <matt@openssl.org>

This patch updates the "DEFAULT" cipherstring to be "ALL:!COMPLEMENTOFDEFAULT:!eNULL". COMPLEMENTOFDEFAULT is now defined internally by a flag on each ciphersuite indicating whether it should be excluded from DEFAULT or not. This gives us control at an individual ciphersuite level as to exactly what is in DEFAULT and what is not. Finally all DES, RC4 and RC2 ciphersuites are added to COMPLEMENTOFDEFAULT and hence removed from DEFAULT. Reviewed-by: NTim Hudson <tjh@openssl.org>
