Hello again, Here is version two of the patches I previously posted here: https://lore.kernel.org/r/20250625131543.5155-1-will@xxxxxxxxxx Changes since v1 include: * Remove virtio_vsock_alloc_skb_with_frags() and instead push decision to allocate nonlinear SKBs into virtio_vsock_alloc_skb() * Remove VIRTIO_VSOCK_DEFAULT_RX_BUF_SIZE and inline its definition along with a comment * Validate the length advertised by the packet header on the guest receive path * Minor tweaks to the commit messages and addition of stable tags Thanks to Stefano for all the review feedback so far.
