* Implementation of an SSL socket. This is a normal connection type |
|
45 |
* socket, implementing SSL over some lower level socket, such as TCP. |
|
46 |
* Because it is layered over some lower level socket, it MUST override |
|
47 |
* all default socket methods. |
|
48 |
* |
|
49 |
* <P> This API offers a non-traditional option for establishing SSL |
|
50 |
* connections. You may first establish the connection directly, then pass |
|
51 |
* that connection to the SSL socket constructor with a flag saying which |
|
52 |
* role should be taken in the handshake protocol. (The two ends of the |
|
53 |
* connection must not choose the same role!) This allows setup of SSL |
|
54 |
* proxying or tunneling, and also allows the kind of "role reversal" |
|
55 |
* that is required for most FTP data transfers. |

* ERROR HANDLING GUIDELINES |
|
66 |
* (which exceptions to throw and catch and which not to throw and catch) |
|
67 |
* |
|
68 |
* . if there is an IOException (SocketException) when accessing the |
|
69 |
* underlying Socket, pass it through |
|
70 |
* |
|
71 |
* . do not throw IOExceptions, throw SSLExceptions (or a subclass) |
|
72 |
* |
|
73 |
* . for internal errors (things that indicate a bug in JSSE or a |
|
74 |
* grossly misconfigured J2RE), throw either an SSLException or |
|
75 |
* a RuntimeException at your convenience. |
|
76 |
* |
|
77 |
* . handshaking code (Handshaker or HandshakeMessage) should generally |
|
78 |
* pass through exceptions, but can handle them if they know what to |
|
79 |
* do. |
|
80 |
* |
|
81 |
* . exception chaining should be used for all new code. If you happen |
|
82 |
* to touch old code that does not use chaining, you should change it. |
|
83 |
* |
|
84 |
* . there is a top level exception handler that sits at all entry |
|
85 |
* points from application code to SSLSocket read/write code. It |
|
86 |
* makes sure that all errors are handled (see handleException()). |
|
87 |
* |
|
88 |
* . JSSE internal code should generally not call close(), call |
|
89 |
* closeInternal(). |

* There's a state machine associated with each connection, which |
|
94 |
* among other roles serves to negotiate session changes. |
|
95 |
* |
|
96 |
* - START with constructor, until the TCP connection's around. |
|
97 |
* - HANDSHAKE picks session parameters before allowing traffic. |
|
98 |
* There are many substates due to sequencing requirements |
|
99 |
* for handshake messages. |
|
100 |
* - DATA may be transmitted. |
|
101 |
* - RENEGOTIATE state allows concurrent data and handshaking |
|
102 |
* traffic ("same" substates as HANDSHAKE), and terminates |
|
103 |
* in selection of new session (and connection) parameters |
|
104 |
* - ERROR state immediately precedes abortive disconnect. |
|
105 |
* - SENT_CLOSE sent a close_notify to the peer. For layered, |
|
106 |
* non-autoclose socket, must now read close_notify |
|
107 |
* from peer before closing the connection. For nonlayered or |
|
108 |
* non-autoclose socket, close connection and go onto |
|
109 |
* cs_CLOSED state. |
|
110 |
* - CLOSED after sending close_notify alert, & socket is closed. |
|
111 |
* SSL connection objects are not reused. |
|
112 |
* - APP_CLOSED once the application calls close(). Then it behaves like |
|
113 |
* a closed socket, e.g.. getInputStream() throws an Exception. |
|
114 |
* |
|
115 |
* State affects what SSL record types may legally be sent: |
|
116 |
* |
|
117 |
* - Handshake ... only in HANDSHAKE and RENEGOTIATE states |
|
118 |
* - App Data ... only in DATA and RENEGOTIATE states |
|
119 |
* - Alert ... in HANDSHAKE, DATA, RENEGOTIATE |
|
120 |
* |
|
121 |
* Re what may be received: same as what may be sent, except that |
|
122 |
* HandshakeRequest handshaking messages can come from servers even |
|
123 |
* in the application data state, to request entry to RENEGOTIATE. |
|
124 |
* |
|
125 |
* The state machine within HANDSHAKE and RENEGOTIATE states controls |
|
126 |
* the pending session, not the connection state, until the change |
|
127 |
* cipher spec and "Finished" handshake messages are processed and |
|
128 |
* make the "new" session become the current one. |
|
129 |
* |
|
130 |
* NOTE: details of the SMs always need to be nailed down better. |

217 |
* IMPORTANT STUFF TO UNDERSTANDING THE SYNCHRONIZATION ISSUES. |
|
218 |
* READ ME * READ ME * READ ME * READ ME * READ ME * READ ME * |
|
219 |
* |
|
220 |
* There are several locks here. |
|
221 |
* |
|
222 |
* The primary lock is the per-instance lock used by |
|
223 |
* synchronized(this) and the synchronized methods. It controls all |
|
224 |
* access to things such as the connection state and variables which |
|
225 |
* affect handshaking. If we are inside a synchronized method, we |
|
226 |
* can access the state directly, otherwise, we must use the |
|
227 |
* synchronized equivalents. |
|
228 |
* |
|
229 |
* The handshakeLock is used to ensure that only one thread performs |
|
230 |
* the *complete initial* handshake. If someone is handshaking, any |
|
231 |
* stray application or startHandshake() requests who find the |
|
232 |
* connection state is cs_HANDSHAKE will stall on handshakeLock |
|
233 |
* until handshaking is done. Once the handshake is done, we either |
|
234 |
* succeeded or failed, but we can never go back to the cs_HANDSHAKE |
|
235 |
* or cs_START state again. |
|
236 |
* |
|
237 |
* Note that the read/write() calls here in SSLSocketImpl are not |
|
238 |
* obviously synchronized. In fact, it's very nonintuitive, and |
|
239 |
* requires careful examination of code paths. Grab some coffee, |
|
240 |
* and be careful with any code changes. |
|
241 |
* |
|
242 |
* There can be only three threads active at a time in the I/O |
|
243 |
* subsection of this class. |
|
244 |
* 1. startHandshake |
|
245 |
* 2. AppInputStream |
|
246 |
* 3. AppOutputStream |
|
247 |
* One thread could call startHandshake(). |
|
248 |
* AppInputStream/AppOutputStream read() and write() calls are each |
|
249 |
* synchronized on 'this' in their respective classes, so only one |
|
250 |
* app. thread will be doing a SSLSocketImpl.read() or .write()'s at |
|
251 |
* a time. |
|
252 |
* |
|
253 |
* If handshaking is required (state cs_HANDSHAKE), and |
|
254 |
* getConnectionState() for some/all threads returns cs_HANDSHAKE, |
|
255 |
* only one can grab the handshakeLock, and the rest will stall |
|
256 |
* either on getConnectionState(), or on the handshakeLock if they |
|
257 |
* happen to successfully race through the getConnectionState(). |
|
258 |
* |
|
259 |
* If a writer is doing the initial handshaking, it must create a |
|
260 |
* temporary reader to read the responses from the other side. As a |
|
261 |
* side-effect, the writer's reader will have priority over any |
|
262 |
* other reader. However, the writer's reader is not allowed to |
|
263 |
* consume any application data. When handshakeLock is finally |
|
264 |
* released, we either have a cs_DATA connection, or a |
|
265 |
* cs_CLOSED/cs_ERROR socket. |
|
266 |
* |
|
267 |
* The writeLock is held while writing on a socket connection and |
|
268 |
* also to protect the MAC and cipher for their direction. The |
|
269 |
* writeLock is package private for Handshaker which holds it while |
|
270 |
* writing the ChangeCipherSpec message. |
|
271 |
* |
|
272 |
* To avoid the problem of a thread trying to change operational |
|
273 |
* modes on a socket while handshaking is going on, we synchronize |
|
274 |
* on 'this'. If handshaking has not started yet, we tell the |
|
275 |
* handshaker to change its mode. If handshaking has started, |
|
276 |
* we simply store that request until the next pending session |
|
277 |
* is created, at which time the new handshaker's state is set. |
|
278 |
* |
|
279 |
* The readLock is held during readRecord(), which is responsible |
|
280 |
* for reading an InputRecord, decrypting it, and processing it. |
|
281 |
* The readLock ensures that these three steps are done atomically |
|
282 |
* and that once started, no other thread can block on InputRecord.read. |
|
283 |
* This is necessary so that processing of close_notify alerts |
|
284 |
* from the peer are handled properly. |
