Meeting Place and Times Tuesday/Thursday: 9:30am – 10:45am  LOV 301 (sometimes at LOV 016) You will work in lab LOV 016  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  Final project can be added to your portfolio

Prerequisites COP 4610  Undergraduate Operating Systems or, COP 5570  Concurrent, Parallel, and Distributed Programming (old Advanced Unix Programming) or,  Proficiency in Unix environment and C, and  General knowledge of operating systems design principles

Class Grading Assignment 1 (individual): 10% Assignment 2 (prob. individual): 5% Assignment 3 (individual): 15% Assignment 4 (individual): 15% Assignment 5 (team + report): 30% Quizzes:25%

Assignments Reading Programming  You will be provided access to a PC (LOV 16) It may need to be shared  First four 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  Raspberry pi  Cellular phone sensors  Virtual devices (virtual machine pass-through)  Solid-state storage (e.g., flash) New kernel features/optimizations  Optimize storage management routines  Security  Assist with ongoing research projects Your ideas?

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 Good editor, IDE (search code) Git (backup, versions) General knowledge of Linux logging subsystem Knowledge of grub commands Virtual machines Kernel debugging tools  Kdb, gdb (on modules)  “Kernel hacking” configuration menu items  “Magic SysRq”

Quizzes Several short quizzes  On average, one quiz per week  Not necessarily announced in advance (Dates on calendar are just illustrative.) Missed quizzes  For excused absences or lateness Make-up arrangements must be made with instructor Usually, an oral examination  Will throw out one quiz (worst score)
