61*0Sstevel@tonic-gate * DECnet object for servicing SSL. We accept the inbound and speak a
62*0Sstevel@tonic-gate * simple protocol for multiplexing the 2 data streams (application and
63*0Sstevel@tonic-gate * ssl data) over this logical link.
64*0Sstevel@tonic-gate *
65*0Sstevel@tonic-gate * Logical names:
66*0Sstevel@tonic-gate * SSL_CIPHER Defines a list of cipher specifications the server
67*0Sstevel@tonic-gate * will support in order of preference.
68*0Sstevel@tonic-gate * SSL_SERVER_CERTIFICATE
69*0Sstevel@tonic-gate * Points to PEM (privacy enhanced mail) file that
70*0Sstevel@tonic-gate * contains the server certificate and private password.
71*0Sstevel@tonic-gate * SYS$NET Logical created by netserver.exe as hook for completing
72*0Sstevel@tonic-gate * DECnet logical link.
73*0Sstevel@tonic-gate *
74*0Sstevel@tonic-gate * Each NSP message sent over the DECnet link has the following structure:
75*0Sstevel@tonic-gate * struct rpc_msg {
76*0Sstevel@tonic-gate * char channel;
77*0Sstevel@tonic-gate * char function;
78*0Sstevel@tonic-gate * short length;
79*0Sstevel@tonic-gate * char data[MAX_DATA];
80*0Sstevel@tonic-gate * } msg;
81*0Sstevel@tonic-gate *
82*0Sstevel@tonic-gate * The channel field designates the virtual data stream this message applies
83*0Sstevel@tonic-gate * to and is one of:
84*0Sstevel@tonic-gate * A - Application data (payload).
85*0Sstevel@tonic-gate * R - Remote client connection that initiated the SSL connection. Encrypted
86*0Sstevel@tonic-gate * data is sent over this connection.
87*0Sstevel@tonic-gate * G - General data, reserved for future use.
88*0Sstevel@tonic-gate *
89*0Sstevel@tonic-gate * The data streams are half-duplex read/write and have following functions:
90*0Sstevel@tonic-gate * G - Get, requests that up to msg.length bytes of data be returned. The
91*0Sstevel@tonic-gate * data is returned in the next 'C' function response that matches the
92*0Sstevel@tonic-gate * requesting channel.
93*0Sstevel@tonic-gate * P - Put, requests that the first msg.length bytes of msg.data be appended
94*0Sstevel@tonic-gate * to the designated stream.
95*0Sstevel@tonic-gate * C - Confirms a get or put. Every get and put will get a confirm response,
96*0Sstevel@tonic-gate * you cannot initiate another function on a channel until the previous
97*0Sstevel@tonic-gate * operation has been confirmed.
98*0Sstevel@tonic-gate *
99*0Sstevel@tonic-gate * The 2 channels may interleave their operations, for example:
100*0Sstevel@tonic-gate * Server msg Client msg
101*0Sstevel@tonic-gate * A, Get, 4092 ---->
102*0Sstevel@tonic-gate * <---- R, get, 4092
103*0Sstevel@tonic-gate * R, Confirm, {hello} ---->
104*0Sstevel@tonic-gate * <---- R, put, {srv hello}
105*0Sstevel@tonic-gate * R, Confirm, 0 ---->
106*0Sstevel@tonic-gate * . (SSL handshake completed)
107*0Sstevel@tonic-gate * . (read first app data).
108*0Sstevel@tonic-gate * <---- A, confirm, {http data}
109*0Sstevel@tonic-gate * A, Put, {http data} ---->
110*0Sstevel@tonic-gate * <---- A, confirm, 0
111*0Sstevel@tonic-gate *
112*0Sstevel@tonic-gate * The length field is not permitted to be larger that 4092 bytes.
