Linux Kernel Package Tutorial

Question

I am trying to understand how part of the data goes through the linux kernel from the application layer to the wire in detail through the kernel. Does anyone know a good place to start or a good tutorial?

Answer 1

The Understanding Linux Kernel book has specific answers for you.

Answer 2

I really don't know, but the big picture looks something like this:

First: Application → Kernel (through the socket obtained as a result of binding to the port)

Inside the kernel: NetFilter <=> TCP / IP stack → network adapter driver

After the kernel: NIC firmware → Wire
