2018-07-01crypto: virtio - Register an algo only if it's supportedFarhan Ali1-6/+75
Register a crypto algo with the Linux crypto layer only if the algorithm is supported by the backend virtio-crypto device. Also route crypto requests to a virtio-crypto device, only if it can support the requested service and algorithm.

2016-12-16crypto: add virtio-crypto driverGonglei1-0/+264
This patch introduces virtio-crypto driver for Linux Kernel. The virtio crypto device is a virtual cryptography device as well as a kind of virtual hardware accelerator for virtual machines. The encryption anddecryption requests are placed in the data queue and are ultimately handled by thebackend crypto accelerators. The second queue is the control queue used to create or destroy sessions for symmetric algorithms and will control some advanced features in the future. The virtio crypto device provides the following cryptoservices: CIPHER, MAC, HASH, and AEAD. For more information about virtio-crypto device, please see: http://qemu-project.org/Features/VirtioCrypto CC: Michael S.
