The head of the company's kernel development, Vojtech Pavlik, said in a media release: "Originally a research project from SUSE Labs, kGraft has quickly shown its promise as a live patching Linux tool for enterprise users."
There are two existing methods of patching a running kernel - Ksplice and OpenVZ Checkpointing. The open source version of the first has not been updated.
Ksplice, which was developed by Ksplice Inc under an open source licence until July 2011 when it was bought by Oracle, is used by the company as an incentive to get companies to use Oracle Linux. Prior to being acquired, it was available for the Red Hat, CentOS, Debian, Ubuntu and Fedora Linux distributions.
The release was announced at the Linux Foundation's Collaboration Summit in Napa, California, where Pavlik also gave a presentation on the new module.
The code will be sent upstream for inclusion in the main Linux kernel.
