Linux versus Unix hot patching

Filed under

Linux
Security

There has always been a debate about how close Linux can get to the real operating system (OS), the core proprietary Unix variants that for two decades defined the limits of non-mainframe scalability and reliability.

But times are changing, and the new narrative may be when will Unix catch up to Linux on critical reliability, availability, and serviceability (RAS) features such as hot patching?

Hot patching, the ability to apply updates to the OS kernel while it is running, is a long sought-after but elusive feature of a production OS.

It is sought after because both developers and operations teams recognise that bringing down an OS instance that is doing critical high-volume work is at best disruptive and at worst a logistical nightmare. Its level of difficulty also makes it somewhat elusive.

There have been several failed attempts and implementations that almost worked, but they were so fraught with exceptions that they were not really useful in production.

Zorin OS 12 as Windows Alternative

GNU
Linux
  • The Linux alternative to Windows 10

    Zorin OS 12 is powered by Linux Kernel version 4.4 and is based on Ubuntu 16.04 LTS. This means it will be supported with security updates until April 2021, stated the report.

  • Ubuntu Based Zorin OS 12 Linux Could Be An Open Source Windows 10 Alternative Many Are Looking For

    Some Linux distributions make their goal of catering to those familiar with Windows clear, and Zorin OS is no exception. The GNOME-based desktop is designed to mimic Windows in some key areas, such as by having a taskbar at the bottom, and the main system menu located to its left. The clock and other system tray icons can be found towards the opposite end of the taskbar.

You Can Run ExTiX Linux with LXQt 0.10.0 and Kernel 4.8 on Intel Compute Stick

Filed under
GNU
Linux

GNU/Linux developer Arne Exton announced the availability of a new build of his ExTiX distribution, which has been designed to run on the Intel Compute Stick device.

ExTiX Build 161119 is the new version of the Linux-based operating system, powered by the latest Linux 4.8 kernel and using the lightweight LXQt 0.10.0 desktop environment as default graphical interface. However, the most important change in this release is that it ships with a kernel engineered to support the Intel Compute Stick mini computer.

"I have made a new version of ExTiX – The Ultimate Linux System. I call it ExTiX 16.5 LXQt for the Intel Compute Stick. Build 161119 is only for Intel Compute Sticks. i.e. you can’t run the system on other computers," said Arne Exton in the announcement. "Build 161119 uses 'my' kernel 4.8.0-26-exton-IntelAtom with special patches."

Linux 4.9-rc6

Filed under
Linux

We're getting further in the rc series, and while things have stayed
pretty calm, I'm not sure if we're quite there yet. There's a few
outstanding issues that just shouldn't be issues at rc6 time, so we'll
just have to see. This may be one of those releases that have an rc8,
which considering the size of 4.9 is perhaps not that unusual.

That said, nothing particular is bothering me all that much, but we've
had some of the VMALLOC_STACK fixups continue to trickle in, so I
worry that we're not quite done there yet. And let's see what
Thorsten's regression list looks like next week. So no decision yet,
it could still go either way.

  • Early Benchmarks Of AMDGPU DRM-Next Code For Linux 4.10

    For those curious if the AMDGPU DRM driver changes that are queued in DRM-Next for Linux 4.10 will bring any performance changes, here are some early numbers.

    This week I carried out some fresh benchmarks using Linux 4.8.7 stable, Linux 4.9 Git as of this week, and the DRM-Next kernel as of this week that carries the AMDGPU changes queued so far for the next kernel version. In terms of the AMDGPU changes for Linux 4.10, see AMDGPU In Linux 4.10 To Have Better Power Management, New VM Manager.

  • Linux 4.9 Has Tear-Free PRIME Offloading Between Intel & AMDGPU

    Quietly landing last week into the mainline Linux kernel as part of the AMDGPU fixes is support for tear-free PRIME offloading between Intel and AMDGPU.

    The drm/amdgpu: Attach exclusive fence to prime exported bo's. (v5) patch was merged fairly late into the Linux 4.9 kernel merge window.

Arduino-Compatible RISC-V and More

  • HiFive1 Is an Open-Source, Arduino-Compatible RISC-V Dev Kit
    Bay Area startup SiFive has announced the Freedom Everywhere 310 (FE310) system-on-chip — the industry’s first commercially-available SoC based on the free, open-source RISC-V architecture, along with the corresponding low-cost, Arduino-compatible HiFive1 development kit.
  • Samsung Defection From ARM to RISC-V.
    It was always thought that, when ARM relinquished its independence, its customers would look around for other alternatives. The nice thing about RISC-V is that it’s independent, open source and royalty-free. And RISC-V is what Samsung is reported to be using for an IoT CPU in preference to ARM.
  • Neutralize ME firmware on SandyBridge and IvyBridge platforms
    First introduced in Intel’s 965 Express Chipset Family, the Intel Management Engine (ME) is a separate computing environment physically located in the (G)MCH chip (for Core 2 family CPUs which is separate from the northbridge), or PCH chip replacing ICH(for Core i3/i5/i7 which is integrated with northbridge).

Moving From Microsoft to GNU/Linux

  • Is Linux the Right Choice for My Business?
    In these hard-economic times, cutting expense is among the keys to the success of a business. Licensing costs can be a huge drain on the wallet of any service. Of course, Microsoft Windows servers are still the standard in a lot of offices, however, there is an unsung hero out there simply waiting to be discovered by more business-owners. This article is obviously describing Linux. While it does have some appeal in both the general public and economic sectors, it is widely used for servers and still not a really popular operating system for workstations but among geeks. Why? You might ask. Microsoft has the marketplace cornered and remains the norm simply by being the standard. This is not to state that Microsoft does not produce quality software application; this post indicates absolutely nothing of the sort. Microsoft got where they are today by their sweat and devoted developers, in no way is this article lessening the quality of Microsoft or their line of products.
  • Moving with SQL Server to Linux? Move from SQL Server to MySQL as well! [Ed: SQL Server DOES NOT (!) run on Linux]
    Over the recent years, there has been a large number of individuals as well as organizations who are ditching the Windows platform for Linux platform, and this number will continue to grow as more developments in Linux are experienced. Linux has for long been the leader in Web servers as most of the web servers run on Linux, and this could be one of the reasons why the high migration is being experienced.

    Does actually Linux community like Microsoft? Does actually Linux community trust Microsoft? I cannot answer the first question for sure, but I have a sure answer for the second question.
