| 25 * Currently, the list of functions called through ss->handshake is: | |
| 26 * | |
| 27 * In sslsocks.c: | |
| 28 * SocksGatherRecord | |
| 29 * SocksHandleReply | |
| 30 * SocksStartGather | |
| 31 * | |
| 32 * In sslcon.c: | |
| 33 * ssl_GatherRecord1stHandshake | |
| 34 * ssl2_HandleClientSessionKeyMessage | |
| 35 * ssl2_HandleMessage | |
| 36 * ssl2_HandleVerifyMessage | |
| 37 * ssl2_BeginClientHandshake | |
| 38 * ssl2_BeginServerHandshake | |
| 39 * ssl2_HandleClientHelloMessage | |
| 40 * ssl2_HandleServerHelloMessage | |
| 41 * | |
| 42 * The ss->handshake function returns SECWouldBlock under these conditions: | |
| 43 * 1. ssl_GatherRecord1stHandshake called ssl2_GatherData which read in | |
| 44 * the beginning of an SSL v3 hello message and returned SECWouldBlock | |
| 45 * to switch to SSL v3 handshake processing. | |
| 46 * | |
| 47 * 2. ssl2_HandleClientHelloMessage discovered version 3.0 in the incoming | |
| 48 * v2 client hello msg, and called ssl3_HandleV2ClientHello which | |
| 49 * returned SECWouldBlock. | |
| 50 * | |
| 51 * 3. SECWouldBlock was returned by one of the callback functions, via | |
| 52 * one of these paths: | |
| 53 * - ssl2_HandleMessage() -> ssl2_HandleRequestCertificate() -> | |
| 54 * ss->getClientAuthData() | |
| 55 * | |
| 56 * - ssl2_HandleServerHelloMessage() -> ss->handleBadCert() | |
| 57 * | |
| 58 * - ssl_GatherRecord1stHandshake() -> ssl3_GatherCompleteHandshake() -> | |
| 59 * ssl3_HandleRecord() -> ssl3_HandleHandshake() -> | |
| 60 * ssl3_HandleHandshakeMessage() -> ssl3_HandleCertificate() -> | |
| 61 * ss->handleBadCert() | |
| 62 * | |
| 63 * - ssl_GatherRecord1stHandshake() -> ssl3_GatherCompleteHandshake() -> | |
| 64 * ssl3_HandleRecord() -> ssl3_HandleHandshake() -> | |
| 65 * ssl3_HandleHandshakeMessage() -> ssl3_HandleCertificateRequest() -> | |
| 66 * ss->getClientAuthData() | |
| 67 * | |
| 68 * Called from: SSL_ForceHandshake (below), | |
| 69 * ssl_SecureRecv (below) and | |
| 70 * ssl_SecureSend (below) | |
| 71 * from: WaitForResponse in sslsocks.c | |
| 72 * ssl_SocksRecv in sslsocks.c | |
| 73 * ssl_SocksSend in sslsocks.c | |
| 74 * | |
| 75 * Caller must hold the (write) handshakeLock. | |

| 1102 * Unless some other fatal alert has been transmitted, each party is | |
| 1103 * required to send a close_notify alert before closing the write side | |
| 1104 * of the connection. The other party MUST respond with a close_notify | |
| 1105 * alert of its own and close down the connection immediately, | |
| 1106 * discarding any pending writes. It is not required for the initiator | |
| 1107 * of the close to wait for the responding close_notify alert before | |
| 1108 * closing the read side of the connection. | |
| 1109 * | |
| 1110 * The second sentence requires that we send a close_notify alert when we | |
| 1111 * have received a close_notify alert. In practice, all SSL implementations | |
| 1112 * close the socket immediately after sending a close_notify alert (which is | |
| 1113 * allowed by the third sentence), so responding with a close_notify alert | |
| 1114 * would result in a write failure with the ECONNRESET error. This is why | |
| 1115 * we don't respond with a close_notify alert. | |
| 1116 * | |
| 1117 * Also, in the unlikely event that the TCP pipe is full and the peer stops | |
| 1118 * reading, the SSL3_SendAlert call in ssl_SecureClose and ssl_SecureShutdown | |
| 1119 * may block indefinitely in blocking mode, and may fail (without retrying) | |
