Welcome to the definitive course on Linux kernel and system architecture, meticulously crafted for learners who want to truly understand how modern operating systems work under the hood.
This course is the result of extensive research and careful organization, designed to guide you through the essential concepts, mechanisms, and design philosophies that shape Linux and its ecosystem. Whether you’re a developer, system administrator, or an enthusiast eager to deepen your technical foundation, this course will equip you with the knowledge to confidently navigate and analyze the Linux kernel and its surrounding technologies.
What You’ll Learn
-
Unix and Linux Design Principles: Discover the foundational philosophies that have shaped Unix and Linux, including modularity, simplicity, and the separation of kernel and userland.
-
Kernel Architecture: Gain a clear understanding of kernel space vs. user space, system call interfaces, and the critical role of the kernel in managing hardware and resources.
-
Process and Memory Management: Explore how Linux handles process scheduling, memory allocation, virtual memory, and advanced topics like NUMA and huge pages.
-
Device Drivers and I/O: Learn about the Linux device model, driver core, and the mechanisms behind device discovery, binding, and hotplugging.
-
Filesystems and Storage: Understand the Virtual Filesystem (VFS) layer, journaling, copy-on-write filesystems, and the intricacies of block layer evolution and I/O scheduling.
-
Networking Internals: Delve into the networking stack, from socket APIs and packet buffers to routing, forwarding, and advanced features like eBPF, XDP, and virtual networking primitives.
-
Security and Isolation: Examine namespaces, cgroups, kernel capabilities, LSM frameworks (SELinux, AppArmor), seccomp, kernel lockdown, and integrity measurement architectures.
-
Virtualization and Containers: Get to grips with KVM, paravirtualized I/O, live migration, overcommit theory, and the kernel guarantees behind container isolation.
-
Observability and Performance: Learn about tracing primitives (ftrace, kprobes, uprobes), performance counters, and how eBPF enables safe, programmable introspection.
