Andrea Parri (Microsoft) 066f3377fb hv_sock: Copy packets sent by Hyper-V out of the ring buffer ... Pointers to VMbus packets sent by Hyper-V are used by the hv_sock driver within the guest VM. Hyper-V can send packets with erroneous values or modify packet fields after they are processed by the guest. To defend against these scenarios, copy the incoming packet after validating its length and offset fields using hv_pkt_iter_{first,next}(). Use HVS_PKT_LEN(HVS_MTU_SIZE) to initialize the buffer which holds the copies of the incoming packets. In this way, the packet can no longer be modified by the host.
