[PATCH v7 0/3] vduse: add support for networking devices

From: Maxime Coquelin
Date: Tue Jan 09 2024 - 06:10:44 EST


This small series enables virtio-net device type in VDUSE.
With it, basic operation have been tested, both with
virtio-vdpa and vhost-vdpa using DPDK Vhost library series
adding VDUSE support using split rings layout (merged in
DPDK v23.07-rc1).

Control queue support (and so multiqueue) has also been
tested, but requires a Kernel series from Jason Wang
relaxing control queue polling [1] to function reliably,
so while Jason rework is done, a patch is added to fail init
if control queue feature is requested.(tested also with DPDK
v23.11).


Changes in v7:
==============
- Fail init only if VIRTIO_NET_F_CTRL_VQ is requested.
- Convert to use BIT_ULL() macro
- Rebased

Changes in v6:
==============
- Remove SELinux support from the series, will be handled
in a dedicated one.
- Require CAP_NET_ADMIN for Net devices creation (Jason).
- Fail init if control queue features are requested for
Net device type (Jason).
- Rebased on latest master.

Changes in v5:
==============
- Move control queue disablement patch before Net
devices enablement (Jason).
- Unify operations LSM hooks into a single hook.
- Rebase on latest master.

Maxime Coquelin (3):
vduse: validate block features only with block devices
vduse: Temporarily fail if control queue feature requested
vduse: enable Virtio-net device type
