[Qemu-devel] [PATCH v2 00/15] virtio-crypto: introduce framework and device emulation |
Date: |
Tue, 13 Sep 2016 11:52:06 +0800 |
Changes since v1:
- rmmove mixed endian-ness handler for virtio-crypto device, just
use little-endian. [mst]
- add sg list support according virtio-crypto spec v10 (will be posted soon).
- fix a memory leak in session handler.
- add a feature page link in qemu.org
(http://qemu-project.org/Features/VirtioCrypto)
- fix some trivial problems, sush as 's/Since 2.7/Since 2.8/g' in
qapi-schema.json
- rebase the latest qemu master tree.
Please review, thanks!
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.
- 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:
http://cryptodev-linux.org/
(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:
https://github.com/gongleiarei/virtio-crypto-linux-driver.git
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
QEMU code also can be accessible from:
https://github.com/gongleiarei/qemu.git
branch virtio-crypto
