Vaughan-Nichols of ZDNet alerted us that Linux 4.0 will provide support for “no-reboot patching.” The gist: When a security patch or other critical OS update comes out, you can apply it .
While rebootless patching is convenient for everyone, it’s a game changer for some applications.
This will walk you through the practical aspects of using Kitsune and introduce you to the Kitsune runtime APIs and xfgen language.
After completing the tutorial, you should be able to use Kitsune to add dynamic updating support to other projects.
These modified versions are available on our Github Page.
Code changes to these programs were small, and experiments show that Kitsune updating support adds essentially no performance overhead.
Kitsune Benchmarks » The best way to learn Kitsune is to follow the tutorial located in the /doc directory of the repository.
For example, web and cloud hosting services normally require customers to experience some downtime while the OS infrastructure is upgraded; with rebootless patching, upgrades happen seamlessly.
Or, imagine upgrades to systems hosting in-memory databases: Right now, you have to checkpoint the DB to stable storage, stop the system, upgrade it, restart it, read the data from stable storage, and restart service.
Open SSH is developed as part of the security conscious Open BSD project, which is led by Theo de Raadt. In Unix and other multitasking computer operating systems, a daemon is a computer program that runs as a background process, rather than being under the direct control of an interactive user.
