Most of this session will focus on Kernel Module Programming. We will briefly talk about the interaction of different layers of operating system from userspace to kernel space. Starting from simple Hello World kernel modules, we will learn the development of more sophisticated modules related to device drivers and interrupt handlers. We will also briefly touch upon the shell scripts and how they can be used to extract system level information. Since, this will be a hands on session, attendees are expected to try the examples on their machines. Basic understanding of operating systems and C programming is expected for the tutorial. ]]>

In this talk, we will explain the functioning of Wireless LANs in theory and in practice. We will present the IEEE 802.11 standard in general and MAC protocols in particular, by discussing the functions of MAC sublayer management entity and the MAC layer frames in detail. We will discuss the changes in the states of a WiFi client as it goes through the process of WiFi communication. Towards the end, we will briefly talk about various vantage points ( at the client side as well as in the air ) that allow us to capture network traffic.]]>

While we understand the complex interplay of OSI layers, in theory, in practice understanding their implementation is a non-trivial task. The implementation details that enables a network interface card to communicate with its peers are oblivious to the end-users. Developers venturing into this domain for the first time often find it hard to find relevant tutorials that enable them to understand these implementation details. The aim of this talk is to provide an overview of WiFi Subsystem implemented in the Linux operating system. Specifically, this talk will explain the sequence of events that occur from application layer till physical layer when a connection is established over WiFi. After this talk, the audience will understand (1) the bird's eye view of Linux WiFi Subsystem, (2) what happens in an operating system when a WiFi card is plugged-in, (3) how is a packet received/transmitted from physical layer to operating system kernel and vice-versa, (4) brief overview of code structure of open-source drivers, and lastly (5) important pointers to kick start driver code modifications.
