[PATCH net-next v2 0/2] Add IP/port information to UDP drop tracepoint

From: Balazs Scheidler <hidden>
Date: 2024-03-19 16:39:17

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.

v2 updates:
  * Addressed review notes by Kuniyuki Iwashima [off-list ref]

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
