[PATCH RFC 4/4] virtio_net: bigger header when VERSION_1 is set

With VERSION_1 virtio_net uses same header size whether mergeable buffers are enabled or not. Signed-off-by: Michael S. Tsirkin --- drivers/net/virtio_net.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/net/virtio_net.c b/drivers/net/virtio_net.c index

[PATCH RFC 3/4] virtio_net: stricter short buffer length checks

Our buffer length check is not strict enough for mergeable buffers: buffer can still be shorter that header + address by 2 bytes. Fix that up. Signed-off-by: Michael S. Tsirkin --- drivers/net/virtio_net.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git

[PATCH RFC 1/4] virtio_net: pass vi around

Too many places poke at [rs]q->vq->vdev->priv just to get the the vi structure. Let's just pass the pointer around: seems cleaner, and might even be faster. Signed-off-by: Michael S. Tsirkin --- drivers/net/virtio_net.c | 36 +++- 1 file changed, 19

[PATCH RFC 2/4] virtio_net: get rid of virtio_net_hdr/skb_vnet_hdr

virtio 1.0 doesn't use virtio_net_hdr anymore, and in fact, it's not really useful since virtio_net_hdr_mrg_rxbuf includes that as the first field anyway. Let's drop it, precalculate header len and store within vi instead. This way we can also remove struct skb_vnet_hdr. Signed-off-by: Michael

[PATCH v2] powernv/iommu: disable IOMMU bypass with param iommu=nobypass

When IOMMU bypass is enabled, a PCI device can read and write memory that was not mapped by the driver without causing an EEH. That might cause memory corruption, for example. When we disable bypass, DMA reads and writes to addresses not mapped by the IOMMU will cause an EEH, allowing us to debug
