Subject: [RFC 0/8] virtio-crypto: add multiplexing mode support
*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.
