Hi folks, Here is version three of the patches I previously posted here:
v1: https://lore.kernel.org/r/[email protected] v2: https://lore.kernel.org/r/[email protected] Changes since v2 include: * Pass payload length as a parameter to virtio_vsock_skb_put() * Reinstate VIRTIO_VSOCK_DEFAULT_RX_BUF_SIZE based on a 4KiB total allocation size * Split movement of bounds check into a separate patch Thanks again to Stefano for all the review feedback so far.
