Furthermore, __icmp_send() can be invokedfrom paths (e.g., link failures, ARP errors, forwarding, AF_PACKET)where skb->transport_header was never initialized (~0U).\nUnder CONFIG_DEBUG_NET=y, calling skb_transport_header(skb) triggersDEBUG_NET_WARN_ON_ONCE(!skb_transport_header_was_set(skb)).\nFix this by:1. Only parsing transport info when iph->protocol == IPPROTO_UDP.2. Using skb_header_pointer() at skb_network_offset(skb) + (iph->ihl << 2)   to safely fetch the UDP header without assuming transport_header is
