Eric Dumazet c1269d3d12 tcp: add tcp_rcvbuf_grow() tracepoint ... Provide a new tracepoint to better understand tcp_rcv_space_adjust() (currently broken) behavior. Call it only when tcp_rcv_space_adjust() has a chance to make a change. I chose to leave trace_tcp_rcv_space_adjust() as is, because commit 6163849d28 ("net: introduce a new tracepoint for tcp_rcv_space_adjust") intent was to get it called after each data delivery to user space. Tested: Pair of hosts in the same rack. Ideally, sk->sk_rcvbuf should be kept small. echo "4096 131072 33554432" >/proc/sys/net/ipv4/tcp_rmem ./netserver perf record -C10 -e tcp:tcp_rcvbuf_grow sleep 30 <launch from client : netperf -H
