need to carry it anymore.

-Subject: [PATCH] net: tighten bad gso csum offset check in virtio_net_hdr
-
-The referenced commit drops bad input, but has false positives.
-Tighten the check to avoid these.
-
-The check detects illegal checksum offload requests, which produce
-csum_start/csum_off beyond end of packet after segmentation.
-
-But it is based on two incorrect assumptions:
-
-1. virtio_net_hdr_to_skb with VIRTIO_NET_HDR_GSO_TCP[46] implies GSO.
-True in callers that inject into the tx path, such as tap.
-But false in callers that inject into rx, like virtio-net.
-Here, the flags indicate GRO, and CHECKSUM_UNNECESSARY or
-CHECKSUM_NONE without VIRTIO_NET_HDR_F_NEEDS_CSUM is normal.
-
-2. TSO requires checksum offload, i.e., ip_summed == CHECKSUM_PARTIAL.
-False, as tcp[46]_gso_segment will fix up csum_start and offset for
-all other ip_summed by calling __tcp_v4_send_check.
-
-Because of 2, we can limit the scope of the fix to virtio_net_hdr
-that do try to set these fields, with a bogus value.
