Major Debian Linux Kernel Patch Fixes 8-Year-Old Privilege Escalation Flaw

Filed under
Linux
Debian

First and foremost, the security update again patches Debian GNU/Linux's kernel against both variants of the Spectre vulnerability (CVE-2017-5715 and CVE-2017-5753). These could allow an attacker that has control over an unprivileged process to read memory from arbitrary addresses, including kernel memory.

While Spectre Variant 2 was mitigated for the x86 architecture (amd64 and i386) via the retpoline compiler feature, Spectre Variant 1 was mitigated by first identifying the vulnerable code sections and then replacing the array access with the speculation-safe array_index_nospec() function.

Linux Foundation: vRAN, OPNFV and CNCF

  • Is vRAN a Natural Fit For a Linux Foundation Project?

    A virtualized radio access network (vRAN) is a key part of the 5G network architecture as defined by the 3GPP. And vRAN is getting a lot of attention from network operators because it promises to lower operator capex and opex costs as well as make it possible for them to add new capabilities to the network more quickly.

    The growing interest in vRAN has prompted the creation of three different groups — the xRAN Forum, the Telecom Infra Project’s OpenRAN Group, and Cisco’s Open vRAN initiative. All of these groups say they are working to make the RAN more open by using standardized interfaces and white box network elements.

  • Open Source Network Functions Virtualization Project Brings NFV Closer to Cloud Native with Sixth Platform Release, OPNFV 'Fraser'

    The OPNFV Project, an open source project within The Linux Foundation that facilitates the development and evolution of Network Functions Virtualization (NFV) components across various open source ecosystems through reference platform development, integration, deployment, and testing, today announced the availability of the sixth OPNFV platform release, OPNFV Fraser. Making the mission of OPNFV more operationally relevant, Fraser advances the state of NFV around cloud native applications and new upstream project integration while continuing end user support as they deploy and test virtualized networks.

  • Cloud Computing in Focus: Serverless, Microservices, KubeCon + CloudNativeCon, and More

    Cloud computing concepts can seem as nebulous as clouds themselves, but in April, we published several cloud-related articles to help clarify a few underlying ideas and look at some specific implementations.

    This month, Swapnil Bhartiya tackled the subject of serverless computing with There’s a Server in Every Serverless Platform. According to a recent whitepaper from the Cloud Native Computing Foundation (CNCF) Serverless Working Group, “serverless computing refers to the concept of building and running applications that do not require server management.” However, as Bhartiya explains, there are still servers involved.

Void Linux Infrastructure In Limbo With Project Leader M.I.A.

Filed under
GNU
Linux

The rolling-release Void Linux independent OS known for its XBPS package manager, use of Runit as an init system rather than systemd, LibreSSL rather than OpenSSL, and other offerings making this Linux distribution fairly different is in a bit of a trouble. The project leader of Void Linux is missing in action, making much of the project's infrastructure inaccessible.

There still are multiple members to the Void Core Team and others working on this independent Linux distribution, but their project leader has "disappeared". There's been no contact since January but no "meaningful contact" in over one year.

Review: Observium open-source network monitoring won't run on Windows but has a great user interface, price

Filed under
Linux
OSS

Open source network-monitoring tools continue to gain in popularity, and Observium came up on our radar as an enterprise-grade offering. Deployed worldwide by large organizations like eBay, PayPal, Twitter and the US Department of Energy, Observium is capable of handling tens of thousands of devices. The client list is impressive, but our test reveals what’s really under the hood.

Observium runs on Linux but can monitor Windows and many other device types. The vendor recommends running Observium on Ubuntu/Debian, but it will also work on distros such as Red Hat/CentOS.

A free e-learning tool for creating digital content

It's common to see a software app stand still—no new versions, no updates. Eventually, it gets overtaken by advancing technology and its user base drifts away. Open source software is not immune to this fate, but it is easier to revive than commercial software, where optimistic accountants cling to the hope that it still holds financial value. eXeLearning (also called eXeLearn, or eXe), an open source XHTML editor that was created with support from Auckland University of Technology, University of Auckland, and Tairawhiti Polytechnic, achieved a measure of popularity among its target audience. The introduction to the version 1 manual described it as "an authoring environment to assist teachers and academics in the design, development, and publishing of web-based learning and teaching materials without the need to become proficient in HTML or complicated web-publishing applications." Despite a few annoying glitches, I liked and recommended that program. However, development stalled around 2010 and eXeLearning fell off my recommended list. eXeLearning is back on my list now.

  • NVIDIA 396.24.02 Linux Driver Brings New Vulkan Extensions
    The NVIDIA 396.24.02 Linux driver is available today and while it's a beta update, it ends up being quite an exciting release thanks to new Vulkan extensions. The newly-supported Vulkan extensions for the Linux driver build include VK_KHR_draw_indirect_count, VK_EXT_global_priority, and VK_KHR_get_display_properties2.
  • Vulkan 1.1.76 Released With KHR_draw_indirect_count & KHR_get_display_properties2
    Vulkan 1.1.76 has just been released ahead of the US Memorial Day weekend with new extensions to excite Vulkan developers. The two new extensions in Vulkan 1.1.176 are VK_KHR_get_display_properties2 and VK_KHR_draw_indirect_count, both of which are notable additions.
  • Vulkan Adds An Exception To Address Wine's Code License Incompatibility
    The Vulkan's documentation/generator being re-licensed from an MIT-style license to the Apache 2.0 license had caused problems for the Wine project supporting newer than Vulkan 1.0.51, but fortunately that issue has been resolved. The previous re-licensing of Vulkan-Docs has caused some problems for the LGPL-licensed Wine code, as we've covered previously, but that technicality has now been addressed with The Khronos Group adding an exception to their license to benefit the Wine project and others using code generated from the Vulkan vk.xml reference file so as not to have (L)GPL and Apache licenses clash.
