  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ngso: do not skip outer ip header in case of ipip and net_failover\nWe encounter a tcp drop issue in our cloud environment. Packet GROed in\nhost forwards to a VM virtio_net nic with net_failover enabled. VM acts\nas a IPVS LB with ipip encapsulation. The full path like:\nhost gro -> vm virtio_net rx -> net_failover rx -> ipvs fullnat\n-> ipip encap -> net_failover tx -> virtio_net tx\nWhen net_failover transmits a ipip pkt (gso_type = 0x0103, which means\nSKB_GSO_TCPV4, SKB_GSO_DODGY and SKB_GSO_IPXIP4), there is no gso\ndid because it supports TSO and GSO_IPXIP4. But network_header points to\ninner ip header." ],
