The following commits added support for printing the real address-65875073ed("net: use %px to print skb address in trace_netif_receive_skb")70713dddf3("net_sched: introduce tracepoint trace_qdisc_enqueue()")851f36e409("net_sched: use %px to print skb address in trace_qdisc_dequeue()") However, tracing the packet traversal shows a mix of hashes and real addresses. Pasting a sample trace for reference- ping-14249 [002] ..... 3424.046612: netif_rx_entry: dev=lo napi_id=0x3 queue_mapping=0 skbaddr=00000000dcbed83e vlan_tagged=0 vlan_proto=0x0000 vlan_tci=0x0000 protocol=0x0800 ip_summed=0 hash=0x00000000 l4_hash=0 len=84 data_len=0 truesize=768 mac_header_valid=1 mac_header=-14 nr_frags=0 gso_size=0 gso_type=0x0 ping-14249 [002] ..... 3424.046615: netif_rx: dev=lo skbaddr=ffffff888e5d1000 len=84 Switch the trace print formats to %p for all the events to have a consistent format of printing the hashed addresses in all cases.
