Subject: [RFC net-next 0/2] Add IP/port information to UDP drop tracepoint

Hi,

In our use-case we would like to recover the properties of dropped UDP
packets. Unfortunately the current udp_fail_queue_rcv_skb tracepoint
only exposes the port number of the receiving socket.

This patch-set will add the source/dest ip/port to the tracepoint, while 
keeping the socket's local port as well for compatibility with previous users
of the tracepoint.

Balazs Scheidler (2):
  net: port TP_STORE_ADDR_PORTS_SKB macro to be tcp/udp independent
  net: udp: add IP/port data to the tracepoint
    udp/udp_fail_queue_rcv_skb
