| 10 | * relationship of job descriptors to shared descriptors (SteveC Dec 10 2008): |
| 11 | * |
| 12 | * --------------- --------------- |
| 13 | * | JobDesc #1 |-------------------->| ShareDesc | |
| 14 | * | *(packet 1) | | (PDB) | |
| 15 | * --------------- |------------->| (hashKey) | |
| 16 | * . | | (cipherKey) | |
| 17 | * . | |-------->| (operation) | |
| 18 | * --------------- | | --------------- |
| 19 | * | JobDesc #2 |------| | |
| 20 | * | *(packet 2) | | |
| 21 | * --------------- | |
| 22 | * . | |
| 23 | * . | |
| 24 | * --------------- | |
| 25 | * | JobDesc #3 |------------ |
| 26 | * | *(packet 3) | |
| 27 | * --------------- |
| 28 | * |
| 29 | * The SharedDesc never changes for a connection unless rekeyed, but |
| 30 | * each packet will likely be in a different place. So all we need |
| 31 | * to know to process the packet is where the input is, where the |
| 32 | * output goes, and what context we want to process with. Context is |
| 33 | * in the SharedDesc, packet references in the JobDesc. |
| 34 | * |
| 35 | * So, a job desc looks like: |
| 36 | * |
| 37 | * --------------------- |
| 38 | * | Header | |
| 39 | * | ShareDesc Pointer | |
| 40 | * | SEQ_OUT_PTR | |
| 41 | * | (output buffer) | |
| 42 | * | (output length) | |
| 43 | * | SEQ_IN_PTR | |
| 44 | * | (input buffer) | |
| 45 | * | (input length) | |
| 46 | * --------------------- |
