/**
|
|
* @brief A transaction used to delete the IKE_SA.
|
|
*
|
|
* Notation as follows:
|
|
* Mx{D} means: Message, with message ID "x", containing a Delete payload
|
|
*
|
|
* The clarifcation Document says in 5.8, that a IKE_SA delete should not
|
|
* be acknowledged with the same delete. This only makes sense for CHILD_SAs,
|
|
* as they are paired. IKE_SAs are not, there is only one for both ends.
|
|
*
|
|
* Normal case:
|
|
* ----------------
|
|
* Mx{D} -->
|
|
* <-- Mx{}
|
|
* Delete request is sent, and we wait for the acknowledge.
|
|
*
|
|
* Special case 1:
|
|
* ---------------
|
|
* Mx{D} -->
|
|
* <-- My{D}
|
|
* My{} -->
|
|
* <-- Mx{}
|
|
* Both initate a delete at the same time. We ack the delete, but wait for
|
|
* our delete to be acknowledged.
|
|
*
|
|
* @b Constructors:
|
|
* - delete_ike_sa_create()
|
|
* - transaction_create() with the appropriate message
