  • ONOS Hummingbird SDN release touts core control function improvements

    ON.Lab’s ONOS Project noted its eighth SDN platform release expands southbound and northbound protocol, legacy device support

    The telecommunications market’s choice of software-defined networking platforms continues to blossom, with the Open Networking Laboratory’s Open Network Operating System Project releasing its latest SDN platform variant under the “Hummingbird” tag.

  • OPNFV Heads Down Colorado Trail

    OPNFV today issued its third software release, ending the agonizing six-month period in which folks had to pronounce and spell Brahmaputra. (See OPNFV Issues Third Software Release.)

    This latest release continues the river theme but is sensibly named Colorado: It has other advantages as well, namely support for key features such as security, IPv6, service function chaining (SFC) testing, virtual private networks and more.

    In addition, Colorado is laying some key groundwork for what lies ahead as the industry comes to terms with the MANO (management and network orchestration) dilemma, says Heather Kirksey, Open Platform for NFV Project Inc. 's executive director.

  • The Linux State Of AMD's Zen x86 Memory Encryption

    With AMD's forthcoming Zen processors is support for some new memory encryption technologies that are of particular benefit for virtualized environments.

    I wrote about Linux patches for AMD memory encryption earlier this year while since then more information has come to light. At last month's Linux Security Summit, David Kaplan presented on these technologies coming with Zen; only today I had come across the slide deck for this presentation.

    The technologies come down to Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV). SME provides memory encryption on a per-page-table basis using AMD's ARM-based security co-processor. AMD SME + SEV are designed against both user-access attacks and physical access attacks with a particular focus on VM / hypervisor security.

  • Improving Fuzzing Tools for More Efficient Kernel Testing

    Fuzz testing (or fuzzing) is a software testing technique that involves passing invalid or random data to a program and observing the results, such as crashes or other failures. Bamvor Jian Zhang of Huawei, who will be speaking at LinuxCon Europe, realized that existing fuzz testing tools -- such as trinity -- can generate random or boundary values for syscall parameters and inject them into the kernel, but they don’t validate whether the results of those syscalls are correct.

  • X.Org's GLAMOR 2D Performance Continues To Be Tuned

    While GLAMOR has already been around for a number of years as a means of providing generic X11 2D acceleration over OpenGL for the X.Org Server, it's a seemingly never-ending process to optimize its code-paths for best performance. More improvements are en route for making GLAMOR 2D faster, which should especially be helpful for Raspberry Pi users making use of the VC4 driver stack on this very slow-speed hardware.

    Benefits to the GLAMOR code in the X.Org Server obviously have the potential to benefit all users of this acceleration mechanism for code going into the xorg-server code-base as opposed to an individual GL driver, but for Raspberry Pi users in particular there is some efforts ongoing by Broadcom's Eric Anholt as well as Keith Packard's never-ending tinkering with the X Server code. GLAMOR continues to be used by default for all AMD GCN GPUs, Nouveau for the latest generations of GPU too, VC4 2D is only supported with GLAMOR, and optionally by other DDX drivers too.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
