NEWS

Tentative agenda for midterms:

  • Monday Nov. 4th: C Language (quizzes)
  • Friday Nov 22nd: C programming + system calls on Filesystem, unbuffered I/O, etc
  • Friday Dec. 6th: Processes, Memory Management, Signals
  • Friday Dec. 22nd: Sockets, Semaphores, Shared Memory

Code Samples

Mon. Oct. 14th: Complex function prortotype and code snippets on switch, loops, etc. --> Examples.txt

Prerequisites

The course is mainly focused on system programming for Unix (Linux) systems.

The objective is to make students able to understand, write and modify, programs interfacing with the Linux operating system and its kernel source code.

So, it is assumed that attendees are able to write programs (using some language) and have a basic kwowledge of the main components of a modern operating system, such as Linux.

Each student should have access to a Linux system (a VM is ok), including the compiler, development tools (make, debugger, etc) and man pages.

Working on other devices, such as Mac or Windows laptop, while possible, it is not recommended due to suble differences in the compiler suite and OS interface.

Exams

The evaluation will be carried out, during the course, through tests quizzes on C and with short programs developed by the students in the classroom.

At the end of the course, the students will be able to accept the result obtained with these tests and verbalize, perhaps after an oral discussion.

As an alternative, or if the result of the tests is not considered acceptable, a complete individual project, written in C, should be developed on topics pertaining the arguments seen during the course.

Thus, there are two options:

  • Pass the midterms (plus, perhaps, an oral discussion)
  • Complete the project (as described in the dedicated section). The project (sources and documentation) must be sent by email a few days (5-7) before the date of the exam.
Write/contact me for any doubts, information, etc.

Project

The project is an individual work item, which must include appropriate documentation (Use cases, functional and non functional requirements, etc).

Each academic year will have a different project.

Here is the description of the project for AA2018/2019 --> Project2018.pdf

Test Midterm

During the course, there will be a number (three or perhaps four) tests, in order to check the knowledge acquired during the lessons.

The score obtained for the tests will be part of the final evaluation and could completely substitute the project (see the above section).

Program

These are the topics that are planned to be described during the course.Of course mileage may vary, depending on time available, etc.

  • Programming environment: compiler, make & makefiles, gdb debugger
  • Recap of the C programming language: variables, costants, operators, expressions, control instructions, functions, pointers, arrays, structures & unions, preprocessor directives
  • Operating system basics (Linux): processes, filesystem, inter-process communication primitives (signals, pipes, semaphores, shared memory)
  • Thread programming: pthread management, mutual exclusion, synchronization
  • Network programming: sockets, raw sockets, sniffers
  • Software vulnerabilities: buffer overflows, arc injection, file infection

Textbooks

  • Daniel P. Bovet, Marco Cesati: Understanding the Linux Kernel
  • Brian Kernighan, Dennis Ritchie: The C Programming Language (2nd Ed.)

Slides and souces used during the lessons

Examples:

System call:

Reading a file, (different approaches): Linked List: List.c

Binary Search Tree: Tree.c

Reading a file into a dynamic array and sort it: bubbleSort.c
