|
* relationship of job descriptors to shared descriptors (SteveC Dec 10 2008):
|
|
*
|
|
* --------------- ---------------
|
|
* | JobDesc #1 |-------------------->| ShareDesc |
|
|
* | *(packet 1) | | (PDB) |
|
|
* --------------- |------------->| (hashKey) |
|
|
* . | | (cipherKey) |
|
|
* . | |-------->| (operation) |
|
|
* --------------- | | ---------------
|
|
* | JobDesc #2 |------| |
|
|
* | *(packet 2) | |
|
|
* --------------- |
|
|
* . |
|
|
* . |
|
|
* --------------- |
|
|
* | JobDesc #3 |------------
|
|
* | *(packet 3) |
|
|
* ---------------
|
|
*
|
|
* The SharedDesc never changes for a connection unless rekeyed, but
|
|
* each packet will likely be in a different place. So all we need
|
|
* to know to process the packet is where the input is, where the
|
|
* output goes, and what context we want to process with. Context is
|
|
* in the SharedDesc, packet references in the JobDesc.
|
|
*
|
|
* So, a job desc looks like:
|
|
*
|
|
* ---------------------
|
|
* | Header |
|
|
* | ShareDesc Pointer |
|
|
* | SEQ_OUT_PTR |
|
|
* | (output buffer) |
|
|
* | (output length) |
|
|
* | SEQ_IN_PTR |
|
|
* | (input buffer) |
|
|
* | (input length) |
|
|
* ---------------------
