8 | * | |
9 | * relationship of job descriptors to shared descriptors (SteveC Dec 10 2008): | |
10 | * | |
11 | * --------------- --------------- | |
12 | * | JobDesc #1 |-------------------->| ShareDesc | | |
13 | * | *(packet 1) | | (PDB) | | |
14 | * --------------- |------------->| (hashKey) | | |
15 | * . | | (cipherKey) | | |
16 | * . | |-------->| (operation) | | |
17 | * --------------- | | --------------- | |
18 | * | JobDesc #2 |------| | | |
19 | * | *(packet 2) | | | |
20 | * --------------- | | |
21 | * . | | |
22 | * . | | |
23 | * --------------- | | |
24 | * | JobDesc #3 |------------ | |
25 | * | *(packet 3) | | |
26 | * --------------- | |
27 | * | |
28 | * The SharedDesc never changes for a connection unless rekeyed, but | |
29 | * each packet will likely be in a different place. So all we need | |
30 | * to know to process the packet is where the input is, where the | |
31 | * output goes, and what context we want to process with. Context is | |
32 | * in the SharedDesc, packet references in the JobDesc. | |
33 | * | |
34 | * So, a job desc looks like: | |
35 | * | |
36 | * --------------------- | |
37 | * | Header | | |
38 | * | ShareDesc Pointer | | |
39 | * | SEQ_OUT_PTR | | |
40 | * | (output buffer) | | |
6ec47334 | 41 | * | (output length) | |
8e8ec596 KP |
42 | * | SEQ_IN_PTR | |
43 | * | (input buffer) | | |
6ec47334 | 44 | * | (input length) | |
