[Qemu-devel] [PATCH 0/3] Vhost: no more leak QEMU virtual addresses to user backend

[Maxime Coquelin]

Before this series, QEMU process virtual addresses are sent to the
user backend as user addresses.

Passing these virtual addresses aren't useful, as the backend doesn't
direct access to QEMU address space.

It does make sense however for kernel backend, which can access QEMU
address space.

This series introduce a new enum set by the backend stating whether it
prefers using QEMU Virtual addresses or Guest physical addresses as
User address, and make vhost-user backend to use Guest physical
addresses.

Maxime Coquelin (3):
  vhost-user: rename VhostUserMemory userspace_addr field to user_addr
  vhost: introduce backend's user address type
  vhost-user: no more leak QEMU virtual addresses to user backend
