When clatd starts with ebpf offloaing, and NETIF_F_GRO_FRAGLIST is enable, several skbs are gathered in skb_shinfo(skb)->frag_list. The first skb's ipv6 header will be changed to ipv4 after bpf_skb_proto_6_to_4, network_header\transport_header\mac_header have been updated as ipv4 acts, but other skbs in frag_list didnot update anything, just ipv6 packets.
udp_queue_rcv_skb will call skb_segment_list to traverse other skbs in frag_list and make sure right udp payload is delivered to user space. Unfortunately, other skbs in frag_list who are still ipv6 packets are updated like the first skb and will have wrong transport header length.

Here is the summary with links: - [v6,1/2] net: fix wrong network header length https://git.kernel.org/netdev/net/c/cf3ab8d4a797 - [v6,2/2] selftests net: add UDP GRO fraglist + bpf self-tests (no matching commit)
You are awesome, thank you!
