This document is a guide to understanding how the Linux kernel version 2. Internet Protocol IP. It is intended as a complete reference for experimenters with overviews, walk throughs, source code explanations, and examples. The first part contains an in depth examination of the code, data structures, and functionality involved with networking. There are chapters on initialization, connections and sockets, and receiving, transmitting, and forwarding packets. The second part contains detailed instructions for modifiying the kernel source code and installing new modules. There are chapters on kernel installation, modules, the proc file system, and a complete example.

The Linux kernel is a monolithic Unixlike computer operating system kernel. The Linux family of operating systems is based on this kernel and deployed on both. This document is an effort to bring together many of these sources into one coherent reference on and guide to modifying the networking code within the Linux kernel. It presents the internal workings on four levels a general overview, more specific examinations of network activities, detailed function walk throughs, and references to the actual code and data structures. It is designed to provide as much or as little detail as the reader desires. This guide was written specifically about the Linux 2. Red Hat 6. 1 distribution hopefully the information provided is general enough that it will still apply across distributions and new kernels. It also focuses almost exclusively on TCPUDP, IP, and Ethernet which are the most common but by no means the only networking protocols available for Linux platforms. As a reference for kernel programmers, this document includes information and pointers on editing and recompiling the kernel, writing and installing modules, and working with the proc file system. It also presents an example of a program that drops packets for a selected host, along with analysis of the results. Between the descriptions and the examples, this should answer most questions about how Linux performs networking operations and how you can modify it to suit your own purposes. This project began in a Computer Science Department networking lab at the University of New Hampshire as an effort to institute changes in the Linux kernel to experiment with different routing algorithms. Fixes an issue in which a computer that is running Windows 7 or Windows Server 2008 R2 stops responding at a black screen. This issue occurs when you try to install. Vulnerability details.

It quickly became apparent that blindly hacking the kernel was not a good idea, so this document was born as a research record and a reference for future programmers. Finally it became large enough and hopefully useful enough that we decided to generalize it, formalize it, and release it for public consumption. As a final note, Linux is an ever changing system and truly mastering it, if such a thing is even possible, would take far more time than has been spent putting this reference together. If you notice any misstatements, omissions, glaring errors, or even typos within this document, please contact the person who is currently maintaining it. The goal of this project has been to create a freely available and useful reference for Linux programmers. Almost all of the code presented requires superuser access to implement.

This is obviously not a real network. The IP addresses are all taken from the block reserved for class B private networks that are not guaranteed to be unique. Most real class B networks would have many more computers, and a network with only eight computers would probably not have a subnet. The connection to the Internet through chrysler would usually be via a T1 or T3 line, and that router would probably be a real router i. Cisco Systems hardware router rather than a computer with two network cards. However, this example is realistic enough to serve its purpose to illustrate the the Linux network implementation and the interactions between hosts, subnets, and networks. Copyright c 2. 00.

It provides a discussion of configurations, introduces the data structures involved, and describes the basics of IP routing. When an application generates traffic, it sends packets through sockets to a transport layer TCP or UDP and then on to the network layer IP. In the IP layer, the kernel looks up the route to the host in either the routing cache or its Forwarding Information Base FIB. If the packet is for another computer, the kernel addresses it and then sends it to a link layer output interface typically an Ethernet device which ultimately sends the packet out over the physical medium. When a packet arrives over the medium, the input interface receives it and checks to see if the packet is indeed for the host computer. If so, it sends the packet up to the IP layer, which looks up the route to the packets destination. If the packet has to be forwarded to another computer, the IP layer sends it back down to an output interface. If the packet is for an application, it sends it up through the transport layer and sockets for the application to read when it is ready. Along the way, each socket and protocol performs various checks and formatting functions, detailed in later chapters. The entire process is implemented with references and jump tables that isolate each protocol, most of which are set up during initialization when the computer boots. See Chapter 3 for details of the initialization process. IP is the standard network layer protocol. It checks incoming packets to see if they are for the host computer or if they need to be forwarded. It defragments packets if necessary and delivers them to the transport protocols. It maintains a database of routes for outgoing packets it addresses and fragments them if necessary before sending them down to the link layer. TCP and UDP are the most common transport layer protocols. UDP simply provides a framework for addressing packets to ports within a computer, while TCP allows more complex connection based operations, including recovery mechanisms for packet loss and traffic management implementations. Either one copies the packets payload between user and kernel space.
