Live patching is a way of updating a Linux kernel without interruption.
Because kernel updates don’t take effect until the system is rebooted, Linux kernel live patching is most commonly used to patch severe Linux kernel vulnerabilities without rebooting servers.
Aside from improved service continuity and uptime, organizations with large server fleets also use live patching to avoid the administrative overhead associated with the coordination and planning needed to reboot multiple systems.
This tutorial will show how to use Kpatch to change the behavior of a running Debian 10 kernel without stopping it, changing the contents of
/proc/uptime (and the
uptime command) so that the system’s reported uptime is 10 years greater.
Were you at AWS re:Invent 2019?
I was, and it was a revelation.
“Will you reboot your Linux server in the next 30 days?”
That’s what I asked almost everyone who came to the KernelCare stand.
A third of you said yes. The main reason? Compliance.
