*NOTE*
The code realization is based on the latest virtio crypto spec:
[PATCH v19 0/2] virtio-crypto: virtio crypto device specification
https://lists.nongnu.org/archive/html/qemu-devel/2017-08/msg05217.html
In session mode, the process of create/close a session
makes we have a least one full round-trip cost from guest to host to guest
to be able to send any data for symmetric algorithms. It gets ourself into
synchronization troubles in some scenarios like a web server handling lots
of small requests whose algorithms and keys are different.
We can support one-blob request (no sessions) as well for symmetric
algorithms, including HASH, MAC services. The benefit is obvious for
HASH service because it's usually a one-blob operation.
Gonglei (3):
virtio-crypto: add stateless crypto request handler
cryptodev: extract one util function
virtio-crypto: add host feature bits support
Longpeng(Mike) (5):
virtio-crypto: add new definations for multiplexing mode
virtio-crypto: add session creation logic for mux mode
virtio-crypto: add dataq operation logic for mux mode
cryptodev: add stateless mode cipher support
cryptodev-builtin: add stateless cipher support
