Hi lartc users,
When a packet arrived to a network device it was stored on a skb structure and then enqueue on a network stack.
One of the tests that I want to do is modify the TCP window size and verify the changes on the bandwidth between two hosts.
To do that I need to know how to modify de packet window size and maybe recalculate the checksum value of the TCP packet.
All I can do is read the information of the packet stored on the skb structure.
I think I saw a patch in patchomatic for iptables to modify window size. Perhaps have a look at that and see if it offers you some clues. I seem to remember the answer is in the ACK packets sent back to the server?
