[RFC PATCH 00/19] vhost-user-rpmb (Replay Protected Memory Block)
Hi,
This is an initial implementation of a vhost-user backend for the
VirtIO RPMB device. The device is currently in the draft of the next
VirtIO specification and describes block device which uses combination
of a key, nonce, hashing and a persistent write counter to prevent
replay attacks (hence Replay Protected Memory Block).
It is implemented as a vhost-user device because we want to
