[PATCH net 0/2] vsock/virtio: make the credit mechanism more robust

[Stefano Garzarella]

This series makes the credit mechanism implemented in the
virtio-vsock devices more robust.
Patch 1 sends an update to the remote peer when the buf_alloc
change.
Patch 2 prevents a malicious peer (especially the guest) can
consume all the memory of the other peer, discarding packets
when the credit available is not respected.

Stefano Garzarella (2):
  vsock/virtio: send a credit update when buffer size is changed
  vsock/virtio: discard packets if credit is not respected
