Subject: [PATCH net-next v4 0/2] tcp: make trace of reset logic complete

From: Jason Xing <kernelxing@...cent.com>

Before this, we miss some cases where the TCP layer could send RST but
we cannot trace it. So I decided to complete it :)

v4
Link: https://lore.kernel.org/all/20240329034243.7929-1-kerneljasonxing@gmail.com/
1. rebased against latest net-next
2. remove {} and add skb test statement (Eric)
3. drop v3 patch [3/3] temporarily because 1) location is not that useful
since we can use perf or something else to trace, 2) Eric said we could
use drop_reason to show why we have to RST, which is good, but this seems
not work well for those ->send_reset() logic. I need more time to
investigate this part.

v3
1. fix a format problem in patch [3/3]

v2
1. fix spelling mistakes

Jason Xing (2):
  trace: adjust TP_STORE_ADDR_PORTS_SKB() parameters
  trace: tcp: fully support trace_tcp_send_reset
