Hi, Currently the Linux virtio-crypto driver registers the crypto algorithm without verifying if the backend actually supports the algorithm. This kernel patch series adds support for registering algorithm with Linux crypto layer, only if the algorithm is supported by the backend device. This also makes the driver more compliant with the virtio-crypto spec [1]. I would appreciate any feedback or comments on this. Thank you Farhan Reference --------- [1] Virtio crypto spec proposal https://lists.gnu.org/archive/html/qemu-devel/2017-12/msg00816.html ChangeLog --------- v2 -> v3 - Add Christian Borntrager's acks for the patches. v1 -> v2 - Modify comment as suggested by Arei (patch 1) - Modify error message as suggested by Arei (patch 2) Farhan Ali (2): crypto/virtio-crypto: Read crypto services and algorithm masks crypto/virtio-crypto: Register an algo only if it's supported drivers/crypto/virtio/virtio_crypto_algs.c | 112 ++++++++++++++++++--------- drivers/crypto/virtio/virtio_crypto_common.h | 25 +++++- drivers/crypto/virtio/virtio_crypto_core.c | 29 +++++++ drivers/crypto/virtio/virtio_crypto_mgr.c | 81 +++++++++++++++++-- 4 files changed, 202 insertions(+), 45 deletions(-) -- 2.7.4
