  • EXT4 Patch For Statx Support

    The statx system call was added to Linux 4.11 for providing enhanced file stats. While the statx() system call is in place for Linux 4.11, not all of the file-systems yet support it.

  • TEE Subsystem Proposed For Linux 4.12 Kernel

    Linaro developers are hoping to merge the generic TEE subsystem into the Linux 4.12 kernel this spring.

    TEE is short for the Trusted Execution Environment and is a trusted OS running in a secure environment, such as TrustZone on ARM CPUs or a separate secure co-processor. We've previously covered the work on TEE for Linux and obviously not everyone is happy about "trusted" computing efforts on Linux and implementations like TEE.

  • Bcachefs Brings New On-Disk Format With Encryption, Better Multi-Device Support
  • Bcachefs - encryption, fsck, and more

    It's been far too long since the last announcement - lots of stuff has been
    happening. The biggest milestone has been all the breaking on disk format
    changes finally landing, but there's been lots of other stuff going on, too.

    On the subject of the breaking on disk format changes - there's an excellent
    chance this'll be the last breaking change, so if you're thinking about trying
    out bcachefs this is an excellent time. Also, if you have a filesystem in the
    old format, code to read your filesystem is available in the bcachefs-v0 braches
    of both linux-bcache and bcache-tools.

Security Leftovers

  • How To Improve The Linux System’s Security Using Firejail
    As you already know, Linux kernel is secure by default. But, it doesn’t mean that the softwares on the Linux system are completely secure. Say for example, there is a possibility that any add-ons on your web browser may cause some serious security issues. While doing financial transactions over internet, some key logger may be active in browser which you are not aware of. Even though, we can’t completely give the bullet-proof security to our Linux box, we still can add an extra pinch of security using an application called Firejail. It is a security utility which can sandbox any such application and let it to run in a controlled environment. To put this simply, Firejail is a SUID (Set owner User ID up on execution) program that reduces the risk of security breaches by restricting the running environment of untrusted applications.

Containers vs. Zones vs. Jails vs. VMs

  • Setting the Record Straight: containers vs. Zones vs. Jails vs. VMs
    I’m tired of having the same conversation over and over again with people so I figured I would put it into a blog post. Many people ask me if I have tried or what I think of Solaris Zones / BSD Jails. The answer is simply: I have tried them and I definitely like them. The conversation then heads towards them telling me how Zones and Jails are far superior to containers and that I should basically just give up with Linux containers and use VMs. Which to be honest is a bit forward to someone who has spent a large portion of her career working with containers and trying to make containers more secure. Here is what I tell them:
  • [Old] Hadoop Has Failed Us, Tech Experts Say

    The Hadoop community has so far failed to account for the poor performance and high complexity of Hadoop, Johnson says. “The Hadoop ecosystem is still basically in the hands of a small number of experts,” he says. “If you have that power and you’ve learned know how to use these tools and you’re programmer, then this thing is super powerful. But there aren’t a lot of those people. I’ve read all these things how we need another million data scientists in the world, which I think means our tools aren’t very good.”

  • [Wine] Packaging changes
    Today we want to announce some important changes regarding the Wine Staging packages provided at repos.wine-staging.com and dl.winehq.org. We completely reworked our build system to make the packages available sooner after a release and also added some new features, like downloading old packages for Debian / Ubuntu. The complete list of changes can be found in the announcement email on the Wine mailing list.
