SUSE Releases Source-Code For kGraft Live Kernel Patching

Nearly two months ago SUSE announced a new way of live-patching the Linux kernel for reducing system downtime in cases of minor kernel changes or security fixes to avoid rebooting the system. This alternative to Ksplice is now publicly available, including the open kernel bits.

This morning during the Linux Foundation Collaboration Summit in Napa Valley was a talk covering SUSE's kGraft and simultaneously on the Internet they released the code to kGraft.

The code to kGraft for the kernel-side work can be found via this Kernel.org Git repository.

Additional information on kGraft can be found via SUSE.com.


Besides Ksplice being the long-standing method of Linux live-kernel patching, which is now owned by Oracle, after kGraft's announcement at SUSE, Red Hat coincidentally announced Kpatch for live kernel patching. It will be interesting to see how SUSE and Red Hat work together upstream to get one or both solutions within the mainline Linux kernel.
