Reiser4 Now Has Support For The Linux 4.7 Kernel

Filed under
Reiser

The Reiser4 file-system now has support for the latest stable Linux kernel series, Linux 4.7.

Released this morning by Edward Shishkin was the updated Reiser4 file-system driver patch that provides compatibility for Linux 4.7.0. The only other change besides porting over to Linux 4.7 is a small returned optimization.

There's been no talk in a few years about attempting to mainline the Reiser4 file-system in the Linux kernel. Thus for now if you want to try out this once-promising file-system, swing by SourceForge to patch your kernel.

  • My assessment of “btrfs”

    In short: Novelist Stephen Elliott (James Franco) find himself drawn to the high-profile Hans Reiser (Christian Slater) murder trial - a case that brings him closer to his own troubled past with father (Ed Harris). Amber Heard, Wilmer Valderrama and Cynthia Nixon also star. (Watch the trailer)

  • The Adderall Diaries

    While Romanowsky gamely tries to negotiate the same structural tricks as the book, which employed the Reiser case as a base camp from which the author could depart and return, in the film it feels more like a subplot despite the cinematic tricks -- the cross-cutting and slo-mo flashbacks -- that the director uses to try to connect the stories. At times it feels flat, other times risible, and only occasionally do the stories resonate in any kind of harmony.

  • My assessment of “btrfs”

    Short version — I will continue to use “ext4” in future installs.

    Note that this a personal view, not a recommendation. My own choice depends on how I use computers and my practices for backup, recovery, etc. Your practices are likely different. Much of this post will be about my considerations in deciding against “btrfs” for my own use.

Reiser4 Now Available For Linux 4.5 Kernel

Filed under
Reiser

The Reiser4 file-system has been updated with support for the Linux 4.5 kernel.

Edward Shishkin, the main Reiser4 developer left working on this out-of-tree file-system, today spun the Reiser4 patches for the Linux 4.5 kernel that also includes a few fixes/changes for satisfying the kernel and compiler. Aside from that, there's nothing new to report today with regard to new Reiser4 file-system features nor any new attempt to try to mainline this file-system code.

Reiser4 Updated For Linux 3.16 With SSD Discard Support

Filed under
Reiser

While Reiser4 doesn't still have any mainline Linux kernel ambitions until receiving any corporate backing, the notoriously known Linux file-system has been updated for Linux 3.16 compatibility and SSD discard support.

Over the weekend the Reiser4 file-system patches were updated for Linux 3.16.1/3.16.2 kernel support and additionally for presenting SSD discard support for the long-in-development Linux FS. This latest Reiser4 file-system work was done by Ivan Shapovalov and Edward Shishkin.

Reiser4 Now Available for the 3.15 kernel, so what?

Filed under
Linux
Reiser

A recent announcement was made stating that the Reiser4 file system, successor to the ReiserFS, was ported to the 3.15 Linux kernel. Following the 2006 conviction and incarceration of the mastermind that original conceived this project (Hans Reiser), a few dedicated developers continued supporting this file system despite the odds stacked against them. In the last decade, the Linux kernel has seen newer file systems, most of which are integrated into the mainline kernel tree (i.e. btrfs, ext4, etc.). Reiser4 was rejected for inclusion some time back, and most of its developers moved on (one or more of which are currently working on btrfs).

Reiser4 Now Available For Linux 3.15

Linux
Reiser

While the Linux 3.16 kernel is now stable, a few days ago the Reiser4 file-system was finally ported to Linux 3.15.

Edward Shishkin released Reiser4 for the Linux 3.15.1 kernel last weekend. Besides being ported to the kernel interface changes for Linux 3.15, there's also two bug-fixes for the out-of-tree file-system. Most of the Reiser4 activity these days continues to just be porting to new kernel versions and bug-fixing. Edward is down to being one of the only main developers left and there's expected to be no effort to mainline the controversial file-system without the support of a major Linux ISV/IHV.

Reiser4 File-System SSD "Discard" Support Gets Revised

Filed under
Linux
Reiser

Ivan Shapovalov is back on track with his Reiser4 file-system contributions.

Shapovalov has been working on Reiser4 support for TRIM/Discard on SSDs. It's been some weeks since the last revision but the fourth version of the patches are now out there for this common file-system feature of being able to discard blocks by informing the solid-state drive about blocks that are no longer in use by the file-system. Most mainline Linux file-systems already support SSD discard, which is generally exposed via the discard mount option -- which is also the case for Reiser4.

5 Best Linux Distros for Security

Security is nothing new to Linux distributions. Linux distros have always emphasized security and related matters like firewalls, penetration testing, anonymity, and privacy. So it is hardly surprising that security conscious distributions are common place. For instance, Distrowatch lists sixteen distros that specialize in firewalls, and four for privacy. Most of these specialty security distributions, however, share the same drawback: they are tools for experts, not average users. Only recently have security distributions tried to make security features generally accessible for desktop users. Read more

  • How IoTivity and AllJoyn Could Combine
    At the Embedded Linux Conference in April, Open Connectivity Foundation (OCF) Executive Director Mike Richmond concluded his keynote on the potential for interoperability between the OCF’s IoTivity IoT framework and the AllSeen Alliance’s AllJoyn spec by inviting to the stage Greg Burns, the chief architect of AllJoyn. Burns briefly shared his opinion that not only was there no major technical obstacle to combining these two major open source IoT specs, but that by taking the best of both standards, a hybrid could emerge that improves upon both. Later in the day, Burns gave a technical overview of how such a hybrid could be crafted in “Evolving a Best-of-Breed IoT Framework.” (See video below.) Burns stated in both talks that his opinions in no way reflect the official position of OCF or the AllSeen Alliance. At the time of the ELC talk in April, Burns had recently left his job as VP of Engineering at Qualcomm and Chair of the Technical Steering Committee at the AllSeen Alliance to take on the position of Chief IoT Software Technologist in the Open Source Technology Center at Intel Corp.

  • New FairWare Ransomware targeting Linux Computers [Ed: probably just a side effect of keeping servers unpatched]
    A new attack called FaireWare Ransomware is targeting Linux users where the attackers hack a Linux server, delete the web folder, and then demand a ransom payment of two bitcoins to get their files back. In this attack, the attackers most likely do not encrypt the files, and if they do retain the files, probably just upload it to a server under their control.
  • How do we explain email to an "expert"?
    This has been a pretty wild week, more wild than usual I think we can all agree. The topic I found the most interesting wasn't about one of the countless 0day flaws, it was a story from Slate titled: In Praise of the Private Email Server The TL;DR says running your own email server is a great idea. Almost everyone came out proclaiming it a terrible idea. I agree it's a terrible idea, but this also got me thinking. How do you explain this to someone who doesn't really understand what's going on? There are three primary groups of people. 1) People who know they know nothing 2) People who think they're experts 3) People who are actually experts
  • Why the term “zero day” needs to be in your brand’s cybersecurity vocabulary
    Linux is “open source” which means anyone can look at the code and point out flaws. In that sense, I’d say Linus Torvalds doesn’t have to be as omniscient as Tim Cook. Linux source code isn’t hidden behind closed doors. My understanding is, all the Linux code is out there for anyone to see, naked for anyone to scrutinize, which is why certain countries feel safer using it–there’s no hidden agenda or secret “back door” lurking in the shadows. Does that mean Android phones are safer? That’s up for debate.
