Course overview

This course provides a deep understanding of the Linux technologies (namely, set-UID/set-GID programs, capabilities, namespaces, cgroups, and seccomp) used to implement container, virtualization, and sandboxing systems. (These are the technologies used to build systems such as Docker, LXC, Firejail, and Flatpak.) The course also provides an understanding of the core APIs used to build system-level applications that run on such systems. Detailed explanations and carefully designed practical exercises provide participants with the knowledge needed both to troubleshoot container and sandboxing systems and to write complex applications that run on those systems. (The course does not cover administering container systems such as Docker and LXC, but by completion of the course participants will have a good understanding of various aspects of the underlying implementation and operation of such systems.)

• Courses are normally five days long, and are delivered either live online, at a public training location, or on-site at customer premises. The content may vary a little, according to specific requests and time constraints, but in broad terms includes the following topics:
  
  
  • Ramp-up on fundamental system programming topics (file I/O, processes, signals, process lifecycle, executing programs)
  • Cgroups
  • Seccomp
  • Classical privileged programs (set-UID, set-GID) and secure programming
  • Capabilities
  • Namespaces (UTS, mount, network, IPC, time, PID, cgroup, and user namespaces)
  • User namespaces in detail
  
  A more detailed list of topics can be found here.
  
  
• The course includes extensive practical sessions, some involving experiments from the shell while others involve writing programs (typically in C).
  
  

Related courses

Note that this course is similar to the 4-day Linux Security and Isolation APIs (M7D-SECISOL02) course, but with the addition of an initial day that covers a range of fundamental system programming topics.

Parts of this course are also available in smaller pieces:

• Linux Capabilities and Namespaces (M7D-CAPNS01, 2 days)
• Linux Control Groups (Cgroups) (M7D-CGROUPS02, 1 day)

Course details

Course outline.

The course employs a lecture+lab format.

Audience and prerequisites

The audience for this course includes designers and developers who are building, troubleshooting, and administering system-level applications for Linux-based container systems.

In order to get the most out of the course, participants should have:

• At least a good reading knowledge of the C programming language. (Note, however, that, except on the first day of the course only a small number of the exercises require writing programs.)
• A knowledge of basic UNIX/Linux shell commands.
• A basic knowledge of make(1) is helpful, but not essential.

Note: previous system programming experience is not required.

Lab sessions

A significant part of the course is spent on practical exercises. The lab sessions also provide participants with the opportunity to obtain one-to-one assistance from the trainer on the course material and exercises.

Course materials

Course participants receive course books of around 500 pages. The course books include all of the slides and exercises presented in the course. Some notable features of the course books are the following:

• The course books have been developed by the trainer, and they are constantly updated based on ongoing changes in the Linux kernel, the GNU C library, and the POSIX standards as well as practical teaching experience in courses.
• The course books are closely integrated with The Linux Programming Interface (TLPI), via numerous references to precise locations in TLPI with more detail on various topics covered in the course.
• The course books include many example programs and exercises not found in TLPI.

In addition to the course book, participants receive a copy of The Linux Programming Interface, in either ebook or printed form (or, when possible, both).

The following samples gives some idea of the course content and style of the course materials:

• Part of the User Namespaces and Capabilities course module.
• The Control Groups v2 Introduction course module.
• Part of the Seccomp course module.
