Oracle Linux kernel developer, Liu Bo, will be giving a presentation on BTRFS Integrity at the Korea Linux Forum on 11th Nov 2014.
In VerifyFS in Btrfs Style, Liu Bo will discuss his current work on extending BTRFS to include integrity verification:
There are different scenarios where we need to check whether we can trust an FS image that was handled by other untrusted parties, that means we need to have every part of the FS unchanged. Security is indeed important at any time. So we look forward to how to verify filesystem integrity efficiently. In this presentation, a btrfs way to verify filesystem integrity is introduced, and the talk will discuss the progress and the performance of the work, as well as challenges it faces and how it addresses them.
The conference schedule includes several other interesting kernel talks, including an update from Greg KH on the past year in mainline kernel development.
ETA: The slides from Liu Bo's talk are now available here.
