* Master the architecture and implementation of zero-downtime Linux kernel updates. *Linux Kernel Live Patching* delivers an in-depth technical exploration of low-level kernel internals, spanning compiler-level `-mfentry` instrumentation, `ftrace` instruction redirection, ORC stack unwinding, and shadow variable memory management. From analyzing the evolutionary mechanics of Ksplice, kpatch, and kGraft to building custom `klp` kernel modules in C, this guide equips kernel engineers and infrastructure security architects with the tools required to deploy rebootless security patches in mission-critical environments.
