I want to know, how does the linux kernel do some stuff (receiving a tcp packet). In what order main tcp functions are called. I want to see both interrupt handler (top half), bottom half and even work done by kernel after user calls "read()".
How can I get a function trace from kernel with some linear time scale?
I want to get a trace from single packet, not the profile of kernel when receiving 1000th of packets.
Kernel is 2.6.18 or 2.6.23 (supported in my debian). I can add some patches to it.
