Add virtio CAN driver patch v13 from upstream kernel mailing
list to enable vhost-user CAN device support in libkrun.
The driver implements a complete CAN bus interface over
Virtio transport, supporting both CAN Classic and CAN-FD.
Changes:
- Add patch 0027-can-virtio-Add-virtio-CAN-driver.patch (v13
from lore.kernel.org/virtualization)
- Enable CAN kernel configs
Fixes:
- Kernel 6.12 compatibility fix for can_priv structure access:
change can.fd.data_bittiming to can.data_bittiming (struct
layout changed in kernel 6.13+)
- Fix FORTIFY_SOURCE panic in virtio_can_start_xmit: set
can_tx_msg->tx_out.length before memcpy() to satisfy
__counted_by_le() buffer bounds checking.
The driver has been tested with rust-vmm vhost-device-can backend.
