Title
idpf: fix checksums set in idpf_rx_rsc()
Summary
In the Linux kernel, the following vulnerability has been resolved: idpf: fix checksums set in idpf_rx_rsc() idpf_rx_rsc() uses skb_transport_offset(skb) while the transport header is not set yet. This triggers the following warning for CONFIG_DEBUG_NET=y builds.

A remote attacker triggers it simply by sending a TCP stream to the host, with no local access of any kind.\nAC:L - Any ordinary TCP flow large enough to be hardware-coalesced enters idpf_rx_rsc(), and the miscomputed length is deterministic \u2014 no race, no memory-layout dependency, no timing window. Hardware GRO is a supported, commonly enabled offload on this class of infrastructure NIC, which CVSS 3.1 directs be assumed as the reasonable worst-case deployment configuration.\nPR:N - The path runs in softirq/NAPI context on packet receive, entirely before any socket lookup, authentication, or credential check. An unauthenticated remote peer reaches it with plain TCP traffic.\nUI:N - The bug triggers automatically during packet reception; no local user or administrator has to open, mount, or interact with anything for the incorrect checksum to be written.\nS:U - The defect and its effects are confined to the kernel networking stack of the receiving host \u2014 the corrupted skb and its checksum stay within the same security authority, with no crossing of a hypervisor, IOMMU, or sandbox boundary.\nC:N - The stale transport-header sentinel is only used in pointer subtraction and then as a scalar in csum_tcpudp_magic(); it is never dereferenced, so there is no out-of-bounds read and no kernel memory or address is exposed.\nI:L - The kernel writes an incorrect TCP checksum into the packet, and tcp_gso_segment() propagates that poisoned seed into every segment emitted on re-segmentation, so a forwarding host transmits corrupted TCP headers. The modification is confined to the checksum field and is not attacker-directed, so the integrity loss is limited rather than arbitrary.\nA:H - On CONFIG_DEBUG_NET builds this fires a WARN in softirq context, which is a kernel panic under the panic_on_warn setting common in hardened and cloud fleets. Independently of that config, every re-segmented TCP packet leaves with a bad checksum and is discarded by the peer, causing complete loss of TCP connectivity through an idpf-equipped router, bridge, or hypervisor \u2014 a denial of service a remote attacker can induce at will by sending traffic."
