Developers Start Debating Whether To Block Password-Based Root SSH Logins For Fedora 31

Filed under
Red Hat
Security

While upstream SSH has disabled password logins for the root user as their default configuration the past number of years and that has carried over into being the out-of-the-box behavior for many operating systems, Fedora continues allowing password-based SSH root log-ins by default. But with the next Fedora release they are thinking about changing that default behavior.

This would allow Fedora to have better security out-of-the-box particularly on servers where OpenSSH tends to be running. The configuration can still be toggled with the "PermitRootLogin" directive of the SSHD configuration.

Events: CopyleftConf, Oggcamp and FOSDEM

  • CopyleftConf 2020

    A week before Software Freedom Conservancy had announced the CopyleftConf 2020. The conference is going to take place on 3 February 2020, Monday, in Brussels, Belgium. The first edition of CopyleftConf took place in February 2019. One can have a look at the videos here The organizers do plan it after Fosdem.

  • The fight to get home from Oggcamp 2019

    I’d heard that parking in Manchester was not only a nightmare and that you would have to sell your children into slavery to pay the parking fee for a few hours so with that in mind I decided to use the train. Now to get to Manchester by car from my house takes around an hour and a half so long as you stick within the speed limit. My train was set to eat two and a half hours from my lifes timeline, but I felt it was a small price to pay given I was only going to do one day of a two-day event. My journey to Oggcamp started at 6.55 am the train took me to Birmingham New Street, where I was due to change for the onward train to Manchester, on the way up to Birmingham, we stopped at Wolverhampton train station. My connection was on-time, and I made myself as comfortable as possible in my reserved seat. To my horror, a rather large gentleman poured himself into the seat next to me and mine if truth be told. We set off heading back the way we came and just for the fun of it and to wind me up a little our first stop was, yes, you guessed it, Wolverhampton train station. I could see the next two hours were going to be a bundle of joy as I tried to look at my phone while feeling that I was confined in an invisible straight jacket if only that were the extent of my problems. Mr Creosote decided that after consuming his breakfast which he had brought on board, it was now time to have a little sleep. “What’s wrong with that?” I hear you ask. Mr Creosote promptly started to snore like farmer Giles’s prized Gloucestershire Old Spot pig. Two hours later, frazzled we arrived in Manchester Mr Creosote had been kind enough to wake up in Macclesfield just enough time for my bladder to fill to bursting along with my fit to burst brain after all that snoring. Oh, and I forgot to mention the lad opposite who while sat underneath a sign saying “Please be considerate to those around you” played videos of South Park amongst other things at full volume on his phone. Never heard of headphones arsehole?

Graphics: Vulkan and Mesa

  • RLSL Allows Running A Subset Of Rust On Vulkan/SPIR-V Enabled GPUs

    There was a recent Khronos meet-up in Munich where Maik Klein of Embark Studios talked about their work on bringing a sub-set of the Rust programming language to Vulkan (SPIR-V) enabled GPUs. RLSL is the project being worked on by the Swedish game studio for opening up Rustlang use for GPUs to benefit from the language's same design advantages, provide a unified front-end, and being able to leverage the existing Rust ecosystem with the likes of Cargo/crates.

  • Raspberry Pi 4's V3D Driver Lands OpenGL ES 3.1 Bits In Mesa 19.3-devel

    The Broadcom "V3D" Gallium3D driver that is most notably used by the new Raspberry Pi 4 boards now is effectively at OpenGL ES 3.1 support within the newest Mesa 19.3 code. We've known that Igalia has been ironing out OpenGL ES 3.1 for V3D after taking over the work from Eric Anholt who left Broadcom earlier this year to go work for Google. Merged this past week was the OpenGL compute shader bits as the main blocker that prevented the V3D open-source Gallium3D driver from exposing GLES 3.1. Following that was a memory violation fix and then explicitly exposing OpenGL ES Shading Language 3.1. That merge request does note that a few more fixes are still needed before V3D will officially pass all of the OpenGL ES 3.1 conformance tests, but at least Mesa 19.3's code is good enough along to enable the support.

Ubuntu: AMD Support, NVIDIA GPU Operator and More

  • Ubuntu 19.10 Doesn't Ship With AMD Navi / Radeon RX 5700 Support Working, But Easy To Enable

    While last week's release of Ubuntu 19.10 "Eoan Ermine" is new enough for Radeon RX 5700 series support with the Linux 5.3 kernel and Mesa 19.2, it doesn't actually work out-of-the-box for these Navi graphics cards. While the principal driver components of the Linux kernel and Mesa3D (for RadeonSI OpenGL and RADV Vulkan) are new enough with Navi support, Ubuntu 19.10's support isn't rounded out because its linux-firmware package isn't new enough for containing the necessary Navi firmware binaries required for the open-source driver usage. So if booting a clean Ubuntu 19.10 install with Radeon RX 5700, you are likely to just see a blank screen.

  • NVIDIA GPU Operator – Simplifying AI/ML Deployments on the Canonical Platform

    Leveraging Kubernetes for AI deployments is becoming increasingly popular. Chances are if your business is involved in AI/ML with Kubernetes you are using tools like Kubeflow to reduce complexity, costs and deployment time. Or, you may be missing out! With AI/ML being the tech topics of the world, GPUs play a critical role in the space. NVIDIA, a prominent player in the GPU space is one of the top choices for most stakeholders in the field. Nvidia takes their commitment to the space a step ahead with the launch of the GPU Operator open-source project at Mobile World Congress LA.
