Benchmarks Of ZFS-FUSE On Linux Against EXT4, Btrfs

Last week we reported that a native ZFS implementation for Linux is soon being released that is based upon the work by Lawrence Livermore National Laboratory to bring Sun's ZFS file-system to Linux as a CDDL-licensed kernel module.

As said though in that article, there is already a ZFS module for FUSE (File-system in User-space) that is already available and with it not living in the GPL-land of the Linux kernel, it is legally allowed, but it does not come without some performance overhead. Over the weekend though there's been some discussions in the related forum thread and elsewhere about the dependability of ZFS-FUSE and what the level of impact on using FUSE really amounts to in real-world usage. We have tested the ZFS-FUSE -- both the latest stable and Git snapshots -- and have compared this alternate ZFS Linux implementation to that of the native EXT4 and Btrfs.

Security Leftovers

  • Security advisories for Monday
  • What's the point of (InfoSec) Certifications?
    When I did the GSE, I absolutely loved the hands-on lab more than anything-else I'd done in the world of SANS or GIAC, outside of Mike Poor's 503 Packet Work book (if you like packets, this is heaven, literally :) ) and the "Capture the Flag" exercises created by Ed Skoudis in 504 and 560. I've also had some amazing instructors like Arrigo Triulzi (Arrigo teaching SEC504 actually convinced me that my future was in InfoSec) and Stephen Sims, however, I am questioning more than ever the value of certifications and to a lesser degree the training courses (which are priced to be exclusive to a tiny minority who are already fairly well off or lucky - I often recommend Coursera or the Offensive Security stuff to candidates when cost is a real issue).
  • Linux Kernel Website Kernel.org Banned By Norton
    Symantec’s automated threat analysis system, Norton Safe Web, claims that Linux kernel’s website kernel.org contains 4 threats and shows a red flag to the users. Looking at Norton’s past record, this threat detection could be just another false warning.
  • Oplcarus: An Anonymous Hacker Reveals The Motivation Behind Latest Attacks
    Here is an account of the operation against banks and financial institutes, named “OpIcarus”, by Anonymous. It reveals the purpose of the cyber attacks, their targets, and the future of OpIcarus operation as told by one of the Anonymous hacktivists with an online name of “The Voice” .
  • Systemd Reverts Its Stance On Letting Users Access Frame-Buffer Devices
    Last week's release of systemd 230 ended up shipping with a change that made it more easy for processes running as a user to snoop on frame-buffer devices. That change has already been reverted for the next systemd update.

Clonezilla Live "Wily"

One of my favourite open source utilities is Clonezilla Live. The Clonezilla project creates tools to assist people in making copies of their hard drives and disk partitions. This can be useful at home for transferring an operating system from one computer to another. It's also a quick way to backup a system's packages and configuration files. In office environments it can be a big time saver to be able to clone one generic operating system onto multiple computers quickly. While installing, configuring and updating an operating system from scratch might take anywhere from half an hour to several hours, Clonezilla can transfer a copy of an operating system across a network in ten to twenty minutes.
