Here is the plan: : 1) Add support for multiple implementations for the same algorithm. : : For example, this lets you have both aes/aes-i586/aes-via_padlock : registered and the one with the highest priority will be used. : The priority will be set by the module with an override option : for the user. : : 2) Extend the interface between crypto API and the underlying : implementations to use scatterlists. : : Wrappers will be provided to extend implementations with existing : single-block interfaces to provide scatterlists. Essentially : it'll be the same as the current scatterlist walking function, : albeit executed conceptually at a lower layer. : : 3) Add support for (raw, as in no scheduler/fail-over) async : implementations through the addition of a callback function : to crypto_tfm and a callback data argument to the existing : top-level crypto entry point functions (encrypt/decrypt/etc). : : 4) Implement implementation registration notification. : : 5) Implement at least one scheduler using the same scatterlist : interface used by async drivers and software implementations. : : It'll work in the manner which I described previously. For : this particular scheduler, there will be one instantiation : that listens for the registration events of underlying : implementations and then reconfigures itself appropriately. : For example, it could simply utilise the hard-coded method : used by OpenBSD. We're still at step 1 at the moment I'm afraid. I did have a set of patches before the release of 2.6.14 that did step 1. However, I've now decided to replace them with a set that uses a flat name space. That is, to find aes-i586 you only need to give the string aes-i586 instead of aes-i586 in addition to the algorithm type "aes".
