/** |
|
40 |
* Implementation of an non-blocking SSLEngine. |
|
41 |
* |
|
42 |
* *Currently*, the SSLEngine code exists in parallel with the current |
|
43 |
* SSLSocket. As such, the current implementation is using legacy code |
|
44 |
* with many of the same abstractions. However, it varies in many |
|
45 |
* areas, most dramatically in the IO handling. |
|
46 |
* |
|
47 |
* There are three main I/O threads that can be existing in parallel: |
|
48 |
* wrap(), unwrap(), and beginHandshake(). We are encouraging users to |
|
49 |
* not call multiple instances of wrap or unwrap, because the data could |
|
50 |
* appear to flow out of the SSLEngine in a non-sequential order. We |
|
51 |
* take all steps we can to at least make sure the ordering remains |
|
52 |
* consistent, but once the calls returns, anything can happen. For |
|
53 |
* example, thread1 and thread2 both call wrap, thread1 gets the first |
|
54 |
* packet, thread2 gets the second packet, but thread2 gets control back |
|
55 |
* before thread1, and sends the data. The receiving side would see an |
|
56 |
* out-of-order error. |

/* |
|
67 |
* There's a state machine associated with each connection, which |
|
68 |
* among other roles serves to negotiate session changes. |
|
69 |
* |
|
70 |
* - START with constructor, until the TCP connection's around. |
|
71 |
* - HANDSHAKE picks session parameters before allowing traffic. |
|
72 |
* There are many substates due to sequencing requirements |
|
73 |
* for handshake messages. |
|
74 |
* - DATA may be transmitted. |
|
75 |
* - RENEGOTIATE state allows concurrent data and handshaking |
|
76 |
* traffic ("same" substates as HANDSHAKE), and terminates |
|
77 |
* in selection of new session (and connection) parameters |
|
78 |
* - ERROR state immediately precedes abortive disconnect. |
|
79 |
* - CLOSED when one side closes down, used to start the shutdown |
|
80 |
* process. SSL connection objects are not reused. |
|
81 |
* |
|
82 |
* State affects what SSL record types may legally be sent: |
|
83 |
* |
|
84 |
* - Handshake ... only in HANDSHAKE and RENEGOTIATE states |
|
85 |
* - App Data ... only in DATA and RENEGOTIATE states |
|
86 |
* - Alert ... in HANDSHAKE, DATA, RENEGOTIATE |
|
87 |
* |
|
88 |
* Re what may be received: same as what may be sent, except that |
|
89 |
* HandshakeRequest handshaking messages can come from servers even |
|
90 |
* in the application data state, to request entry to RENEGOTIATE. |
|
91 |
* |
|
92 |
* The state machine within HANDSHAKE and RENEGOTIATE states controls |
|
93 |
* the pending session, not the connection state, until the change |
|
94 |
* cipher spec and "Finished" handshake messages are processed and |
|
95 |
* make the "new" session become the current one. |
|
96 |
* |
|
97 |
* NOTE: details of the SMs always need to be nailed down better. |
|
98 |
* The text above illustrates the core ideas. |
