Subject: [PATCH v2 0/1] virtio-vsock: Fix unbound rx buffer

From: Gerard Garcia <ggarcia@...c.uab.cat>

This patch applies over VSOCK RFC v6.

Reset connection and close rx socket when the sender is ignoring our
announced available buffer. This avoids a DoS.

v2:
 * Get vvs->rx_lock lock before checking if next packet is going to
    overflow the rx buffer.

  Fix unbound rx buffer
