Hi,
Fortunately I wrote a seminar paper some years ago at university about
exactly that topic. It might help and should still be up to date in all
important regards. https://github.com/richi235/ftrace-paper
I used ftrace to trace the way of a packet, the pdf is in Document/
Cheers,
-- Richard

Hi,
In the following example from net/dccp/proto.c the pointer given
put_user() is casted to (int __user *) although the value to copy is a
unsigned long. Is this (correctness and security wise) sane? Because as
I understand it put_user() determines the amount it copies from the
pointer type.

Hi,
If reordering causes TCP to believe packets are lost, there will
probably be other issues as well, like sending of useless retransmits. I would
rather try to detect this kind of reordering and ignore dupacks and rely only
on timeouts to detect loss.
Well this is exactly how TCP-PR works
Hello,
I'm Richard Sailer and I've started implementing an alternative congestion
control algorithm for linux,
capable of maintaining high throughput during persistent packet reordering
(TCP-PR).
Before continuing my learning and work I want to send a coordinative
mail to the netdev list
