How Linux Kernel Live Patching Keeps Servers Running
transcript
show notes
We dive into kpatch and kGraft, the technologies that let system administrators apply critical security fixes to a running Linux kernel without a single reboot. In an era where uptime is currency and maintenance windows are vanishing, understanding how live patching works—by hot-swapping compiled code in memory—is essential for modern infrastructure teams. We explore the mechanics of function graph trampoline, the safety checks involved, and why this capability has become a standard expectation for enterprise-grade server stacks rather than a niche experimental feature.
