1.64 + * DECnet object for servicing SSL. We accept the inbound and speak a
1.65 + * simple protocol for multiplexing the 2 data streams (application and
1.66 + * ssl data) over this logical link.
1.67 + *
1.68 + * Logical names:
1.69 + * SSL_CIPHER Defines a list of cipher specifications the server
1.70 + * will support in order of preference.
1.71 + * SSL_SERVER_CERTIFICATE
1.72 + * Points to PEM (privacy enhanced mail) file that
1.73 + * contains the server certificate and private password.
1.74 + * SYS$NET Logical created by netserver.exe as hook for completing
1.75 + * DECnet logical link.
1.76 + *
1.77 + * Each NSP message sent over the DECnet link has the following structure:
1.78 + * struct rpc_msg {
1.79 + * char channel;
1.80 + * char function;
1.81 + * short length;
1.82 + * char data[MAX_DATA];
1.83 + * } msg;
1.84 + *
1.85 + * The channel field designates the virtual data stream this message applies
1.86 + * to and is one of:
1.87 + * A - Application data (payload).
1.88 + * R - Remote client connection that initiated the SSL connection. Encrypted
1.89 + * data is sent over this connection.
1.90 + * G - General data, reserved for future use.
1.91 + *
1.92 + * The data streams are half-duplex read/write and have following functions:
1.93 + * G - Get, requests that up to msg.length bytes of data be returned. The
1.94 + * data is returned in the next 'C' function response that matches the
1.95 + * requesting channel.
1.96 + * P - Put, requests that the first msg.length bytes of msg.data be appended
1.97 + * to the designated stream.
1.98 + * C - Confirms a get or put. Every get and put will get a confirm response,
1.99 + * you cannot initiate another function on a channel until the previous
1.100 + * operation has been confirmed.
1.101 + *
1.102 + * The 2 channels may interleave their operations, for example:
1.103 + * Server msg Client msg
1.104 + * A, Get, 4092 ---->
1.105 + * <---- R, get, 4092
1.106 + * R, Confirm, {hello} ---->
1.107 + * <---- R, put, {srv hello}
1.108 + * R, Confirm, 0 ---->
1.109 + * . (SSL handshake completed)
1.110 + * . (read first app data).
1.111 + * <---- A, confirm, {http data}
1.112 + * A, Put, {http data} ---->
1.113 + * <---- A, confirm, 0
1.114 + *
1.115 + * The length field is not permitted to be larger that 4092 bytes.
