[Qemu-devel] [RFC v1 0/2] Detect & register virtio-crypto algos only if it can be supported by backend

Posted by Farhan Ali 5 years, 10 months ago

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
