  • Open-Source NVIDIA/Nouveau Changes Submitted For Linux 5.8

    There hasn't been too much to report on the open-source NVIDIA "Nouveau" kernel driver in some time since the enabling of Turing and no apparent progress on re-clocking to allow the graphics cards to hit their rated clock frequencies (the longstanding, number one limitation for this open-source driver), but some changes were sent in today for the upcoming Linux 5.8 kernel merge window.

  • Linux 5.8 Set To Optionally Flush The L1d Cache On Context Switch To Increase Security

    The Linux kernel patches that have been spearheaded by Amazon AWS engineers to optionally flush the L1 data cache on each context switch have now been queued in the x86/mm branch ahead of the upcoming Linux 5.8 kernel cycle.

    This L1d cache flushing on context switches is being done in light of the various CPU security issues that have come to light in recent times and acknowledging there are likely other yet to be discovered vulnerabilities. Flushing the L1d cache on context switches helps fend off data from being snooped or leaked via side channels.

  • Linux 5.8 To See Support For POWER10's Prefixed Instructions

    Beyond the usual excitement of numerous x86 and Arm hardware advancements each cycle, Linux 5.8 is bringing new IBM POWER enablement work.

    Recently there has been an uptick in open-source/Linux enablement work for the forthcoming POWER10 and that holds true for Linux 5.8. There has been a patch series going around recently for introducing prefixed instruction support on the POWER front for a "future revision of the ISA." That work is now ready and queued ahead of the Linux 5.8 cycle opening up in early June.

  • What sort of SSH keys our users use or have listed in their authorized keys files

    My first surprise is that we have so many DSA keys listed, since they're no longer supported (and those 380 ssh-dss keys are across 203 different people). People clearly don't clean out their authorized keys files very often. 670 people have RSA keys, 13 have Ed25519 keys, and 15 have some form of ECDSA keys (which implies that a few people list a bunch of ECDSA keys).

    However, that's just what people have sitting around in their authorized keys files, not what actually gets used. What actually gets used is a somewhat different picture. Here are the numbers for how many different keys of each type have been used over the course of 2020 so far: [...]

  • Microsoft is blocking the Windows 10 May 2020 Update on lots of devices [Ed: Microsoft cannot even patch its own software without breaking it]

    Microsoft is preventing a large number of devices from updating to the Windows 10 May 2020 Update. While the software company released the update last week, Microsoft has quietly acknowledged that there are a number of known issues preventing the update from being installed on a variety of PCs. Microsoft has a list of 10 issues it’s currently investigating, and 9 of them have resulted in a “compatibility hold” which stops the Windows 10 May 2020 Update from being installed via Windows Update. One issue involving unexpected errors or reboots with always-on, always-connected devices, affects devices like Microsoft’s Surface Pro 7 or Surface Laptop 3.

  • Insights into hybrid cloud: Here's what to consider

    Our interactions with businesses can happen in person, on the web, on our mobile devices, in marketplaces or via APIs. To enable these interactions, IT organizations are increasingly being driven towards hybrid IT architectures involving private cloud, public cloud, edge computing, AI/ML and more to provide multiple different routes to the customer. This mixed use of public and private clouds, possibly with some degree of workload portability, integration, orchestration, and unified management across those clouds is often referred to as hybrid cloud computing. Research shows that improving business agility and increasing IT agility are key drivers for organizations that are implementing a hybrid cloud strategy.
