Linux System Programming with Project. Level 1. (P103)

Go beyond simple Linux programming and learn how to develop the highly performant systems used in today’s software applications. Through the EmbLogic course on Advanced Linux System Programming-L1, you will get familiar with the Linux kernel architecture, process creation, namespaces, daemons, followed by event programming using epoll, timerfd, and signalfd. Learn scheduling, memory mapping, file input-output operations, POSIX threads, and synchronization techniques along with diagnosing concurrent issues. Apply your knowledge in practice and create a High-Concurrency Event Router, having an edge triggered event loop, thread pool, and shared memory mapped data. This course is intended for Linux programmers with a basic understanding of the topic.

Introduction

Welcome to Advanced Linux System Programming-L1: Advanced Linux System Programming. This course is meant for those who have some basic knowledge of C, Linux and wish to transition into the realm of professional system programming. This course is intended to be taken by programmers who are familiar with basic IPC and threads. It is geared to teach you the subtleties of the user/kernel interface. You will go beyond the basics of execution to learn about high-performance, event-driven designs using epoll, complex memory management with mmap and concurrency designs.

Program Overview

Organized into five technical modules and an integrated project, the program progresses from Linux architecture and process internals to event-driven concurrency, memory management, advanced synchronization and scheduling. Participants develop epoll-based reactor loops, incorporate timerfd and signalfd, and examine POSIX clocks and signal handling. Memory-focused topics cover mmap, mprotect, madvise, vectored I/O, synchronous writes, and debugging with Valgrind and AddressSanitizer. Threading topics include read–write locks, spinlocks, barriers, thread-local storage, and concurrency hazards. The concluding High-Concurrency Event Router combines an edge-triggered event loop handling simulated incoming connections, timeout handling, graceful shutdown, synchronized worker threads, and shared memory-mapped lookup data in one C application.
