/* SAs are held in a table.
|

* Entries in this table are referenced by IPsecSAref_t values.
|
||||
* IPsecSAref_t values are conceptually subscripts. Because
|
||||
* we want to allocate the table piece-meal, the subscripting
|
||||
* is implemented with two levels, a bit like paged virtual memory.
|
||||
* This representation mechanism is known as an Iliffe Vector.
|
||||
*
|
||||
* The Main table (AKA the refTable) consists of 2^IPSEC_SA_REF_MAINTABLE_IDX_WIDTH
|
||||
* pointers to subtables.
|
||||
* Each subtable has 2^IPSEC_SA_REF_SUBTABLE_IDX_WIDTH entries, each of which
|
||||
* is a pointer to an SA.
|
||||
*
|
||||
* An IPsecSAref_t contains either an exceptional value (signified by the
|
||||
* high-order bit being on) or a reference to a table entry. A table entry
|
||||
* reference has the subtable subscript in the low-order
|
||||
* IPSEC_SA_REF_SUBTABLE_IDX_WIDTH bits and the Main table subscript
|
||||
* in the next lowest IPSEC_SA_REF_MAINTABLE_IDX_WIDTH bits.
|
||||
*
|
||||
* The Maintable entry for an IPsecSAref_t x, a pointer to its subtable, is
|
||||
* IPsecSAref2table(x). It is of type struct IPsecSArefSubTable *.
|
||||
*
|
||||
* The pointer to the SA for x is IPsecSAref2SA(x). It is of type
|
||||
* struct ipsec_sa*. The macro definition clearly shows the two-level
|
||||
* access needed to find the SA pointer.
|
||||
*
|
||||
* The Maintable is allocated when IPsec is initialized.
|
||||
* Each subtable is allocated when needed, but the first is allocated
|
||||
* when IPsec is initialized.
|
||||
*
|
||||
* IPsecSAref_t is designed to be smaller than an NFmark so that
|
||||
* they can be stored in NFmarks and still leave a few bits for other
|
||||
* purposes. The spare bits are in the low order of the NFmark
|
||||
* but in the high order of the IPsecSAref_t, so conversion is required.
|
||||
* We pick the upper bits of NFmark on the theory that they are less likely to
|
||||
* interfere with more pedestrian uses of nfmark.
