Hi, yongji.
In vduse patches serial[1], you said "The support for other device types can be added after the security issue of corresponding device driver is clarified or fixed in the future."
What does this "security issue" mean?

Do you mean that vduse device is untrusted, so we should check config or data transferred from vduse to virtio module? Or something others? Because I found you added some validation in virtio module just like this patch[2].

Thanks! Xiangdong Liu
