61 | * DECnet object for servicing SSL. We accept the inbound and speak a |
62 | * simple protocol for multiplexing the 2 data streams (application and | |
63 | * ssl data) over this logical link. | |
64 | * | |
65 | * Logical names: | |
40720ce3 MC |
66 | * SSL_CIPHER Defines a list of cipher specifications the server |
67 | * will support in order of preference. | |
d02b48c6 | 68 | * SSL_SERVER_CERTIFICATE |
40720ce3 MC |
69 | * Points to PEM (privacy enhanced mail) file that |
70 | * contains the server certificate and private password. | |
71 | * SYS$NET Logical created by netserver.exe as hook for completing | |
72 | * DECnet logical link. | |
d02b48c6 RE |
73 | * |
74 | * Each NSP message sent over the DECnet link has the following structure: | |
40720ce3 | 75 | * struct rpc_msg { |
d02b48c6 RE |
76 | * char channel; |
77 | * char function; | |
78 | * short length; | |
79 | * char data[MAX_DATA]; | |
80 | * } msg; | |
81 | * | |
82 | * The channel field designates the virtual data stream this message applies | |
83 | * to and is one of: | |
84 | * A - Application data (payload). | |
85 | * R - Remote client connection that initiated the SSL connection. Encrypted | |
86 | * data is sent over this connection. | |
87 | * G - General data, reserved for future use. | |
88 | * | |
89 | * The data streams are half-duplex read/write and have following functions: | |
90 | * G - Get, requests that up to msg.length bytes of data be returned. The | |
91 | * data is returned in the next 'C' function response that matches the | |
92 | * requesting channel. | |
93 | * P - Put, requests that the first msg.length bytes of msg.data be appended | |
94 | * to the designated stream. | |
95 | * C - Confirms a get or put. Every get and put will get a confirm response, | |
96 | * you cannot initiate another function on a channel until the previous | |
97 | * operation has been confirmed. | |
98 | * | |
99 | * The 2 channels may interleave their operations, for example: | |
100 | * Server msg Client msg | |
101 | * A, Get, 4092 ----> | |
102 | * <---- R, get, 4092 | |
103 | * R, Confirm, {hello} ----> | |
104 | * <---- R, put, {srv hello} | |
105 | * R, Confirm, 0 ----> | |
40720ce3 | 106 | * . (SSL handshake completed) |
d02b48c6 RE |
107 | * . (read first app data). |
108 | * <---- A, confirm, {http data} | |
109 | * A, Put, {http data} ----> | |
110 | * <---- A, confirm, 0 | |
111 | * | |
112 | * The length field is not permitted to be larger that 4092 bytes. | |
113 | * | |
