Security Bugs at CPU Level Again

Filed under
Security
  • Google and Microsoft disclose new CPU flaw, and the fix can slow machines down

    Microsoft and Google are jointly disclosing a new CPU security vulnerability that’s similar to the Meltdown and Spectre flaws that were revealed earlier this year. Labelled Speculative Store Bypass (variant 4), the latest vulnerability is a similar exploit to Spectre and exploits speculative execution that modern CPUs use. Browsers like Safari, Edge, and Chrome were all patched for Meltdown earlier this year, and Intel says “these mitigations are also applicable to variant 4 and available for consumers to use today.”

    However, unlike Meltdown (and more similar to Spectre) this new vulnerability will also include firmware updates for CPUs that could affect performance. Intel has already delivered microcode updates for Speculative Store Bypass in beta form to OEMs, and the company expects them to be more broadly available in the coming weeks. The firmware updates will set the Speculative Store Bypass protection to off-by-default, ensuring that most people won’t see negative performance impacts.

  • Spectre variants 3a and 4

    Intel has, finally, disclosed two more Spectre variants, called 3a and 4. The first ("rogue system register read") allows system-configuration registers to be read speculatively, while the second ("speculative store bypass") could enable speculative reads to data after a store operation has been speculatively ignored. Some more information on variant 4 can be found in the Project Zero bug tracker. The fix is to install microcode updates, which are not yet available.

  • Red Hat Says It'll Soon Fix the Speculative Store Bypass Security Vulnerability

    Red Hat informed us today that they are aware of the recently disclosed Speculative Store Bypass (CVE-2018-3639) security vulnerability and will soon release updates to mitigate the issue on all of its affected products.

    Speculative Store Bypass (CVE-2018-3639) is a security vulnerability recently unearthed by various security researchers from Google and Microsoft, and it appears to be a fourth variant of the Spectre hardware bug publicly disclosed earlier this year in modern microprocessor, and later discovered to affect billions of devices. The Speculative Store Bypass vulnerability appearently lets an unprivileged attacker to bypass restrictions and gain read access to privileged memory.

  • AMD AOCC 1.2 Code Compiler Offers Some Performance Benefits For EPYC

    Last month AMD released the AOCC 1.2 compiler for Zen systems. This updated version of their branched LLVM/Clang compiler with extra patches/optimizations for Zen CPUs was re-based to the LLVM/Clang 6.0 code-base while also adding in experimental FLANG support for Fortran compilation and various other unlisted changes to their "znver1" patch-set. Here's a look at how the performance compares with AOCC 1.2 to LLVM Clang 6.0 and GCC 7/8 C/C++ compilers.

  • More Roads And Faster Browsers

    And it's exactly what is happening with our Web pages. Browsers become more performant. So developers instead of using this extra performance to make the page extra-blazingly fast, we use it to pack more DOM nodes, CSS animations and JavaScript driven user experiences.

  • 9 Best Free Python Integrated Development Environments

    Python is a widely used general-purpose, high level programming language. It’s easy to read and learn. It’s frequently used for science, data analysis, and engineering. With a burgeoning scientific community and ecosystem, Python is an excellent environment for students, scientists and organizations that develop technology software.

    One of the essential tools for a budding Python developer is a good Integrated Development Environment (IDE). An IDE is a software application that provides comprehensive facilities to programmers for software development.

    Many coders learn to code using a text editor. And many professional Python developers prefer to stay with their favourite text editor, in part because a lot of text editors can be used as a development environment by making use of plugins. But many Python developers migrate to an IDE as this type of software application offers, above all else, practicality. They make coding easier, can offer significant time savings with features like autocompletion, and built-in refactoring code, and also reduces context switching. For example, IDEs have semantic knowledge of the programming language which highlights coding problems while typing. Compiling is ‘on the fly’ and debugging is integrated.

  • Want to Debug Latency?

    In the recent decade, our systems got complex. Our average production environments consist of many different services (many microservices, storage systems and more) with different deployment and production-maintenance cycles. In most cases, each service is built and maintained by a different team — sometimes by a different company. Teams don’t have much insight into others’ services. The final glue that puts everything together is often a staging environment or sometimes the production itself!

    Measuring latency and being able to react to latency issues are getting equally complex as our systems got more complex. This article will help you how to navigate yourself at a latency problem and what you need to put in place to effectively do so.

  • The open source AsteroidOS is a new alternative to Wear OS

    AsteroidOS is a new Linux-based open source operating system that can be used as a replacement to Wear OS.

    A small team of developers have been hard at work on the smartwatch platform for the last four years. As the culmination of their efforts, this week the first stable version was made available to the public. It plays nice with a few Wear OS-compatible smartwatches.

  • Das blinkenlights are back thanks to RPi revival of the PDP-11

    The designers left the I2C port of the Raspberry Pi free for hacks, and “it is not very hard to add support for such things in the simh emulator, so the PiDP-11 can use them as I/O”.

    The SR switches on the PiDP-11's SR switches can be set to boot various operating systems (this part is a work in progress), so instead of RSX-11MPlus users can choose BSD, DOS-11, Unix System 6 or System 7 and the like.

  • Extreme downhill free-riding game 'Descenders' just had a huge update, needs a quick fix on Linux

    Descenders is an extreme downhill free-riding game currently in Early Access and their first major update just went live. I've been quite a big fan of it, as it showed a massive amount of promise at the initial release.

    I held off on covering this update right away, since the released version of the update broke the 64bit Linux version. Nearly a week later and no fix, so here's how you can fix it manually:

    Right click on it in your Steam library and go to properties, then hit the Local Files tab up the top and press Browse Local Files… once there, open the Descenders_Data folder, go into the Plugins folder and delete "libfmod.so".

  • Open-world roguelike RPG 'Stoneshard' will have Linux support, nearly hit the Kickstarter goal

    Stoneshard [Official Site] is a pretty good sounding open-world RPG, it's currently on Kickstarter with a promise of Linux support and they've nearly hit their goal. With 26 days left to go, they've hit $28K of their $30K goal, so it looks like they will manage it easily.

    Inspired by the likes of Diablo, ADOM, Darkest Dungeon and more, they have a lot to live up to in terms of their inspiration. What makes it sound quite interesting, is the survival elements you heal to deal with like diseases, broken bones, mental health and more.

  • Mesa 18.1 Officially Released as the Most Advanced Linux Graphics Stack Series

    The development team behind the open-source Mesa graphics stack announced over the weekend the general availability of the final Mesa 18.1 release for Linux-based operating systems.

    The Mesa 18.1 series comes approximately two months after the 18.0 branch, which probably most GNU/Linux distributions are using these days, and which already received its fourth maintenance updates. Mesa 18.1 introduces a few new features across all supported graphics drivers, but it's mostly another stability update.

  • Mach64 & Rendition Drivers Now Work With X.Org Server 1.20

    Anyone happening to have an ATI Mach 64 graphics card from the mid-90's or a 3Dfx-competitor Rendition graphics card also from the 90's can now enjoy the benefits of the recently released X.Org Server 1.20.

    Mach 64 and Rendition are among the X.Org DDX (2D) drivers still being maintained for the X.Org Server. Even though using either of these two decade old graphics cards would be painfully slow with a Linux desktop stack from today especially if paired with CPU and memory from that time-frame, the upstream X.Org developers still appear willing to maintain support for these vintage graphics processors. Well, at least as far as ensuring the drivers still build against the newest software -- we've seen before out of these old drivers that they are updated to work for new releases, but at times can actually be broken display support for years before anyone notices with said hardware.

Tesla Compliance

  • It Only Took Six Years, But Tesla Is No Longer Screwing Up Basic Software Licenses

    Tesla is actually doing it. The electric car maker is starting to abide by open source software licenses that it had previously ignored, and releasing the code it’s sat on for over six years, according to Electrek.

    Tesla’s super smart cars, specifically the sporty Model S sedan and Model X SUV, incorporate a lot of open source software, from Linux, the open source operating system, to BusyBox, a collection of tools that are useful when working with Linux and other UNIX environments (like macOS). All open source software is released under licenses and one of the most popular licenses is the GPL, or General Public License.

  • Tesla releases some of its software to comply with open source rules

    Tesla makes some of the most popular electric vehicles out there and the systems in those cars rely on open source software for operating systems and features. Some of that open source software that is used in Tesla products has a license agreement that requires Tesla to at least offer the user access to the source code. Tesla hasn’t been making that offer.

  • Tesla open sources some of its Autopilot source code

    ELECTRIC CAR MAKER Tesla tends to keep the details of its work under lock and key, but now Elon Musk's company is plonking some of its automotive tech source code into the open source community.

    Tesla dumped some of its code used to build the foundations of its Autopilot semi-autonomous driving tech and the infotainment system found on the Model S and Model X cars, which makes uses of Nvidia's Tegra chipset, on GitHub.

    Even if you're code-savvy, don't go expecting to build your own autonomous driving platform on top of this source code, as Tesla has still kept the complete Autopilot framework under wraps, as well as deeper details of the infotainment system found in its cars. But it could give code wranglers a better look into how Tesla approaches building infotainment systems and giving its cars a dose of self-driving smarts.

  • Tesla releases source code

    Tesla has taken its first step towards compliance with the GNU General Public Licence (GPL) by releasing some of its source code.

    The car maker has opened two GitHub repositories which contain the buildroot material used to build the system image on its Autopilot platform, and the kernel sources for the boards and the Nvidia-based infotainment system in the Model S and Model X.

Librem 13: A few problems

I bought my old Lenovo Thinkpad X1 Carbon (1st gen.) when I entered grad school for my Master's program, in 2012. And after six years, the Thinkpad still ran well, but it was getting old, so I figured it was time for a change. I went back and forth about what kind of system should replace my laptop. I don't travel that much, so I figured a desktop would be better. And I could get a bigger screen. After going back and forth on the decision, I decided to get a laptop. I don't often travel with a laptop, but when I do, I prefer to use my primary system so I don't have to keep things synced. Of course, I wanted my system to run Linux. Purism is aimed at the Linux laptop market, and I wanted to support that. So I bought a Librem 13. I've had it now for about a week, and I love it now. But I'll be honest, I didn't love it right out of the box. I'd like to note two issues for folks who are thinking about getting a Librem laptop, so you aren't surprised like I was. Read more

Linux 4.17-rc7

So this week wasn't as calm as the previous weeks have been, but despite that I suspect this is the last rc. This week we had the whole "spectre v4" thing, and yes, the fallout from that shows up as part of the patch and commit log. But it's not actually dominant: the patch is pretty evenly one third arch updates, one third networking updates, and one third "rest". The arch updates are largely - although not exclusively - spectre v4. The networking stuff is mostly network drivers, but there's some core networking too. And "the rest" is just that - misc drivers (rdma, gpu, other), documentation, some vfs, vm, bpf, tooling.. The bulk of it is really pretty trivial one-liners, and nothing looks particularly scary. Let's see how next week looks, but if nothing really happens I suspect we can make do without an rc8. Shortlog appended as usual. Go out and test. Read more
