Subject: [PATCH v1 00/14] virtio-crypto: introduce framework and device emulation

This patch series realize the framework and emulation of a new
virtio crypto device, which is similar with virtio net device.
 - I introduce the cryptodev backend as the client of virtio crypto device
   which can be realized by different methods, such as cryptodev-linux in my series,
   vhost-crypto kernel module, vhost-user etc.
 - The patch set abides by the virtio crypto speccification v9.
 - The virtio crypto support symmetric algorithms (including CIPHER and algorithm chainning)
   at present, except HASH, MAC and AEAD services.
 - unsupport hot plug/unplug cryptodev client at this moment.

Cryptodev-linux is a device that allows access to Linux kernel cryptographic drivers;
thus allowing of userspace applications to take advantage of hardware accelerators.
It can be found here:


(please use the latest version)

To use the cryptodev-linux as the client, the cryptodev.ko should be insert on the host.

 # enter cryptodev-linux module root directory, then
 make;make install

then configuring QEMU shows:

 jemalloc support  no
 avx2 optimization no
 cryptodev-linux support yes

QEMU can then be started using the following parameters:

qemu-system-x86_64 \
    [...] \
        -cryptodev type=cryptodev-linux,id=cryptodev0 \
        -device virtio-crypto-pci,id=crypto0,cryptodev=cryptodev0 \

The front-end linux kernel driver (Experimental at present) is publicly accessible from:

After insmod virtio-crypto.ko, you also can use cryptodev-linux test the crypto function
in the guest. For example:

linux-guest:/home/gonglei/cryptodev-linux/tests # ./cipher -
requested cipher CRYPTO_AES_CBC, got cbc(aes) with driver virtio_crypto_aes_cbc
AES Test passed
requested cipher CRYPTO_AES_CBC, got cbc(aes) with driver virtio_crypto_aes_cbc
requested cipher CRYPTO_AES_CBC, got cbc(aes) with driver virtio_crypto_aes_cbc
Test passed

Please review, thanks!

QEMU code also can be accessible from:
