Meeting Place and Times Tuesday/Thursday: 9:30am – 10:45am  LOV 103 (sometimes at MCH 202) You will work in lab MCH 202  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 corrupting  Can bring into the lab for demos

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  Understand and make changes to the sources  Use internal kernel services  Design and implement a kernel module  Modify/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 (MCH 202) 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)  Future course lab project  Add functionality to an existing device driver May partially include upgrading to a recent version of the kernel

Some Possible Team Projects New kernel features/optimizations  Optimize storage management routines  Security  Assist with ongoing research projects  Scheduling (CPU, block layer) Your ideas?

BEWARE Assignments may be very time consuming  Non-deterministic error  Obscure error symptoms May not have much information about where/when an error occurred Fewer and more difficult to setup debugging tools  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 usage Kernel debugging tools  Kdb, gdb (on modules)  “Kernel hacking” configuration menu items  “Magic SysRq”

Quizzes Several short quizzes  Not necessarily announced in advance Will throw out one quiz (worst score) Missed quizzes  For excused absences or lateness No make-ups for missed quizzes For excused absences or lateness  The missing quizzes will be dropped
