So I can put this in next, the issue I think is that of security: currently selinux can if necessary block access to creating virtio block devices. But if we have more than one type we need a way for selinux to block specific types. Can be a patch on top but pls work to address. Another question is that with this userspace can inject packets directly into net stack. Should we check CAP_NET_ADMIN or such? > [1]: https://lore.kernel.org/lkml/CACGkMEtgrxN3PPwsDo4oOsnsSLJfEmBEZ0WvjGRr3whU+QasUg@xxxxxxxxxxxxxx/T/ > > v2 -> v3 changes: > ================= > - Use allow list instead of deny list (Michael) > > v1 -> v2 changes: > ================= > - Add a patch to disable CVQ (Michael) > > RFC -> v1 changes: > ================== > - Fail device init if it does not support VERSION_1 (Jason) > > Maxime Coquelin (3): > vduse: validate block features only with block devices > vduse: enable Virtio-net device type > vduse: Temporarily disable control queue features > > drivers/vdpa/vdpa_user/vduse_dev.c | 51 +++++++++++++++++++++++++++--- > 1 file changed, 47 insertions(+), 4 deletions(-) > > -- > 2.41.0 _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
