Course Overview

This course provides an in-depth understanding of Linux kernel hacking, including configuring, compiling, and installing a Linux kernel, making changes to kernel sources, designing and implementing kernel modules and device drivers, and measuring performance. Students will work on lab projects and have the opportunity to add their final project to their portfolio. Prerequisites include knowledge of Unix and C, and a general understanding of operating systems design principles.

  1. Course Overview Mark Stanovich COP 5641 / CIS 4930

  2. Instructors • Lead Instructor: Mark Stanovich • Office: 105-E Love Building • Office hours • After class and by appointment (email) • TA: Muye Liu • Office hours: TBA • Class Websites • http://ww2.cs.fsu.edu/~stanovic/teaching/ldd/ • Blackboard

  3. 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

  4. 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

  5. Applicability of Kernel Hacking Skills • Software engineering • Concurrent programming • Thesis and dissertation • Employment • Final project can be added to your portfolio

  6. 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

  7. Course Material • Lecture notes (posted at the class website) • Required textbook • Linux Kernel Development (3rd Ed) • ISBN: 978-0672329463

  8. Course Material Recommended additional textbook Linux Device Drivers, 3rd Edition ISBN: 0-596-00590-3 Online version (free) http://www.lwn.net/Kernel/LDD3

  9. 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%

  10. 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

  11. 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

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

  13. 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

  14. 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

  15. 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”

  16. 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

  17. Class Grading 91% - 100% A 89% - 90% A- 85% - 88% B+ 81% - 84% B 79% - 80% B- 75% - 78% C+ 71% - 74% C 69% - 70% C- 64% - 68% D+ 61% - 63% D 59% - 60% D- 0% - 58% F

  18. Computer Accounts, etc. Blackboard account (@my.fsu.edu) Grade posting via Blackboard Card activation for MCH 202 lab Fill out survey Need your FSU card number Your choice of a 4 digit PIN #

  19. Course Policies Attendance mandatory Honor code: read your student handbook Students with disabilities Report to Student Disability Resource Center Bring me a letter within the first week of class

  20. Things for you to do • Fill out survey form and turn in at the beginning of Thursday’s class • Reading • Syllabus • Start with LKD Chapters 1 and 2 (quick overview) • Then read LDD Chapters 1 and 2 for more depth • Familiarize yourself with Assignment 1
