Meeting Place and Times Monday – Friday: 12:30am – 1:45pm

LOV 301 (sometimes at LOV 016) In addition

You will spend lots of time on projects Projects will need to be done in the lab,

unless you have a PC that you: Don't mind trashing, through kernel bugs Can bring into the lab for demos Have your own device

Course Objectives

Make yourself into a Linux kernel “hacker”, who can: Configure, compile, and install a Linux kernel Do the same for a kernel module Navigate and read the Linux kernel sources Use the API for internal kernel services Design and implement a kernel module Modify, or design and implement a device driver Measure the performance of your implementation

Applicability of Kernel Hacking Skills

Software engineering Concurrent programming Thesis and dissertation Employment

Prerequisites

COP 4610 Undergraduate Operating Systems

or, COP 5570 Advanced Unix Programming

Grade will be reduce by 1% for each missed class

Exceptions: Documented religious holidays and emergency Cases pre-approved by the instructor

Assignments

Reading Programming

You will be provided access to a PC (LOV 16) It may need to be shared

First three assignments: lab. exercises Last assignment: team projects

Each member will evaluate the contribution of the other team members

Warning: they get more difficult, exponentially

Some Possible Team Projects

Device drivers Video cards Cellular phone sensors LED devices Solid-state storage (e.g., flash)

New kernel features/optimizations Mechanisms to optimize flash deletes Mechanisms to track and categorize storage I/Os Mechanisms to perform secure deletion

BEWARE

Assignments may be very time consuming Non-deterministic bugs Obscure bug symptoms

Not much information about where an error occurred Need frequent reboots and OS reinstallations

Implications Start your projects early You are responsible for backing up your work

BEWARE

If you plan to use your own computer You will need to bring in your machine to

demonstrate your code You might trash your hard drives

Some Useful Tools

Virtual machines VMWare Xen Virtual PC

User Mode Linux (UML) These take time to learn and install

Will not help when you get to a real device driver No time to cover them in class You will need to teach yourself

Quizzes

Several short quizzes On average, one quiz per week Not necessarily announced in advance

(Dates on calendar are just illustrative.)

No make-ups for missed quizzes For excused absences or lateness

The missing quizzes will be dropped
