virtio: Protect vqs list access

2021-08-26T12:35:04+00:00

[ Upstream commit 0e566c8f0f2e8325e35f6f97e13cde5356b41814 ] VQs may be accessed to mark the device broken while they are created/destroyed. Hence protect the access to the vqs list. Fixes: e2dcdfe95c0b ("virtio: virtio_break_device() to mark all virtqueues broken.")

virtio-mem: don't read big block size in Sub Block Mode

2021-07-20T14:00:34+00:00

[ Upstream commit 500817bf5e110ad9b7138bc582971bb7ee77d6f7 ] We are reading a Big Block Mode value while in Sub Block Mode when initializing. Fortunately, vm->bbm.bb_size maps to some counter in the vm->sbm.mb_count array, which is 0 at that point in time. No harm done; still, this was unintended and is not future-proof.

virtio_pci_modern: correct sparse tags for notify

2021-05-04T08:19:59+00:00

When switching virtio_pci_modern to use a helper for mappings we lost an __iomem tag. Restore it. Reported-by: kernel test robot Fixes: 9e3bb9b79a71 ("virtio_pci_modern: introduce helper to map vq notify area") Signed-off-by: Michael S. Tsirkin

virtio_pci_modern: __force cast the notify mapping

2021-05-04T08:19:58+00:00

When switching virtio_pci_modern to use a helper for mappings we lost an __iomem tag. We should restore it. However, virtio_pci_modern is playing tricks by hiding an iomem pointer in a regular vq->priv pointer. Which is okay as long as it's all contained within a single file, but we need to __force cast the value otherwise we'll get sparse warnings.

virtio-pci library: report resource address

2021-05-03T08:55:52+00:00

Sometimes it might be useful to report the capability physical address. One example is to report the physical address of the doorbell in order to be mapped by userspace.

virito_pci libray: hide vp_modern_map_capability()

No user now and the capability should not be setup externally. Instead, every access to the capability should be done via virtio_pci_modern_device.

virtio_pci_modern: hide vp_modern_get_queue_notify_off()

2021-05-03T08:55:51+00:00

All users (both virtio-pci library and vp_vdpa driver) has been switched to use vp_modern_map_vq_notify(). So there's no need to export the low level helper of vp_modern_get_queue_notify_off().
