-/*-
- * DECnet object for servicing SSL. We accept the inbound and speak a
- * simple protocol for multiplexing the 2 data streams (application and
- * ssl data) over this logical link.
- *
- * Logical names:
- * SSL_CIPHER Defines a list of cipher specifications the server
- * will support in order of preference.
- * SSL_SERVER_CERTIFICATE
- * Points to PEM (privacy enhanced mail) file that
- * contains the server certificate and private password.
- * SYS$NET Logical created by netserver.exe as hook for completing
- * DECnet logical link.
- *
- * Each NSP message sent over the DECnet link has the following structure:
- * struct rpc_msg {
- * char channel;
- * char function;
- * short length;
- * char data[MAX_DATA];
- * } msg;
- *
- * The channel field designates the virtual data stream this message applies
- * to and is one of:
- * A - Application data (payload).
- * R - Remote client connection that initiated the SSL connection. Encrypted
- * data is sent over this connection.
- * G - General data, reserved for future use.
- *
- * The data streams are half-duplex read/write and have following functions:
- * G - Get, requests that up to msg.length bytes of data be returned. The
- * data is returned in the next 'C' function response that matches the
- * requesting channel.
- * P - Put, requests that the first msg.length bytes of msg.data be appended
- * to the designated stream.
- * C - Confirms a get or put. Every get and put will get a confirm response,
- * you cannot initiate another function on a channel until the previous
- * operation has been confirmed.
- *
- * The 2 channels may interleave their operations, for example:
- * Server msg Client msg
- * A, Get, 4092 ---->
- * <---- R, get, 4092
- * R, Confirm, {hello} ---->
- * <---- R, put, {srv hello}
- * R, Confirm, 0 ---->
- * . (SSL handshake completed)
- * . (read first app data).
- * <---- A, confirm, {http data}
- * A, Put, {http data} ---->
- * <---- A, confirm, 0
- *
- * The length field is not permitted to be larger that 4092 bytes.
