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

From: Stefano Garzarella
Date: Thu Oct 17 2019 - 08:44:11 EST

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
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
