From: Jason Xing <kernelx...@tencent.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-kerneljasonx...@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 include/trace/events/net_probe_common.h | 20 ++++++------ include/trace/events/tcp.h | 42 +++++++++++++++++++++++-- include/trace/events/udp.h | 2 +- net/ipv4/tcp_ipv4.c | 7 ++--- net/ipv6/tcp_ipv6.c | 3 +- 5 files changed, 56 insertions(+), 18 deletions(-) -- 2.37.3
