Samsung Laptop Bug Is Not Linux Specific 215

Posted by timothy
from the using-french-or-korean-does-it-too dept.
First time accepted submitter YurB writes "Matthew Garrett, a Linux kernel developer who was investigating the recent Linux-on-Samsung-in-UEFI-mode problem, has bricked a Samsung laptop using a test userspace program in Windows. The most fascinating part of the story is on what is actually causing the firmware boot failure: 'Unfortunately, it turns out that some Samsung laptops will fail to boot if too much of the [UEFI] variable storage space is used. We don't know what "too much" is yet, but writing a bunch of variables from Windows is enough to trigger it. I put some sample code here — it writes out 36 variables each containing a kilobyte of random data. I ran this as an administrator under Windows and then rebooted the system. It never came back.'"

Linux Foundation's Secure Boot Pre-Bootloader Released 178

Posted by timothy
from the what-about-the-pre-pre-pre-bootloader? dept.
hypnosec writes "The Linux Foundation's UEFI Secure Boot pre-bootloader for independent Linux distros and software developers has finally been released. Announcing the release of the secure boot system James Bottomley noted that the signed pre-bootloader was delivered by Microsoft on February 6th. Bottomley has released two validated files: PreLoader.efi and HashTool.efi. Bottomley has also created a bootable mini-USB image that provides 'an EFI shell where the kernel should be and uses Gummiboot to boot.' Just last week the pre-bootloader had to be rewritten to accommodate booting of all versions of Linux."

Moving the Linux Kernel Console To User-Space 311

Posted by Soulskill
from the cuddly-console-seeks-loving-home dept.
jones_supa sends this quote from Phoronix: "David Herrmann has provided an update on his ambitious initiative to kill off the Linux kernel console. Herrmann has long been working on making the Linux kernel CONFIG_VT option unnecessary for providing a Linux console by punting it off to user-space. The Linux kernel VT console hasn't been changed much in the past two decades and Herrmann is hoping to see it replaced with a user-space solution he's been developing that would allow for multi-seat support, a hardware-accelerated console, full internalization, and other features."

How Red Hat Hires 113

Posted by timothy
from the hands-off-my-foot dept.
New submitter markfeffer, Senior Editor at Dice, writes "Red Hat's hired about 600 people in its last three fiscal quarters, and it's going to keep hiring – about 900 to 1,000 more this year. The company's primarily looking for software and technical support engineers, along with salespeople who can help strengthen its cloud-technology capabilities. They want people with strong technical skills, of course, but the company puts a premium on those who've taken the time to research its business and send in a resume that's custom-tailored to the job opening."

CES: Jono Bacon Talks Up Ubuntu for Phones (Video) 93

Posted by Roblimo
from the a-smart-phone-for-human-beings-and-other-creatures dept.
One of the more interesting conversations Tim Lord had at CES this year was with Ubuntu Community Manager Jono Bacon, who was showing off the Ubuntu Phone that is supposed to be released later this year. According to the Ubuntu website, it "delivers a magical phone that is faster to run, faster to use and fits perfectly into the Ubuntu family." Big words, but if Ubuntu parent Canonical can live up to them, the mobile phone market may soon have an interesting new operating system competitor to shake things up.

Linux-Friendly Mini PC Fast Enough For Steam Games 93

Posted by Soulskill
from the tiny-penguins-with-hats dept.
crookedvulture writes "Barebones mini PCs have been around for a while, and the latest one from Zotac is pretty unique. For $270, the Zbox ID42 offers a Sandy Bridge CPU, a discrete GeForce graphics processor, and all the integrated I/O and networking you'd expect from a modern PC. You have to add your own memory, hard drive, and operating system, but the latter shouldn't cost you a dime. The Zbox works well with not only Windows, but also Linux. Ubuntu even recognizes the included remote, which can be used to wake up the system, control XBMC, and navigate Steam's Big Picture interface. Team Fortress 2 for Linux is actually playable, albeit at a relatively low resolution and detail level. The hardware seems better suited to casual games. Zotac also makes a Plus version of the Zbox that comes bundled with RAM and a hard drive, but it costs an extra $130, and you can get much better components if you add them yourself. The user-friendly chassis makes filling out the system a trivial undertaking."

Ubuntu Smartphone Shipping In October 102

Posted by Soulskill
from the just-in-time-for-clergy-appreciation-month dept.
An anonymous reader writes "Smartphones running the open source Ubuntu operating system will be available to customers beginning in October 2013, Canonical CEO Mark Shuttleworth told CIO Journal. Ubuntu will be available on a full range of devices, including desktop and tablet computers, potentially providing corporate IT executives a way to reduce the number of devices they purchase and manage, and would allow users to access all manner of corporate data through a single, pocket-sized device. 'You can share Windows apps to the phone desktop,' said Mr. Shuttleworth during a meeting in New York Tuesday." Jon Brodkin adds, "Canonical is taking community input on what the core applications (e-mail, calendar, clock/alarm, weather, file manager, document viewer, YouTube, Facebook, and Twitter) should look like. The best aspects of community proposals will hopefully make it into Ubuntu phones when they finally hit the market sometime toward the end of 2013 or beginning of 2014. Take a look at the best designs Canonical has received so far."

Open Source ARM Mali Driver Runs Q3A Faster Than the Proprietary Driver 71

Posted by Unknown Lamer
from the hit-the-fraglimit dept.
An anonymous reader writes "The lima driver project, the open source reverse engineered graphics driver for the ARM Mali, now has Quake 3 Arena timedemo running 2% faster than the ARM Binary driver." There's a video showing it off. Naturally, a few caveats apply; the major one is that they don't have a Free shader compiler and are forced to rely on the proprietary one from ARM, for now.

Microsoft May Be Seeking Protection From Linux With Dell Loan 270

Posted by Soulskill
from the nice-protection-racket-if-you-can-get-it dept.
alphadogg writes "Microsoft's $2 billion loan to Dell is a sign that the software maker wants to influence hardware designs in a post-PC world while protecting itself from the growing influence of Linux-based operating systems in mobile devices and servers, according to analysts. As the world's third-largest PC maker, Dell is important to the success of Microsoft's server and PC software. Even though Microsoft's loan does not represent a big part of the total value of the transaction, the software maker does not throw around money lightly and its participation in the deal might be an attempt by the software maker to influence hardware designs in the post-PC world of touch laptops, tablets and smartphones, analysts said. It may also be an attempt to secure the partnership and to stop the PC maker from looking toward alternative operating systems like Linux, analysts said. Dell offers Linux servers and in late November introduced a thin and light XPS 13 laptop with a Linux-based Ubuntu OS, also code-named Project Sputnik. Major PC makers in recent months have also introduced laptops with Chrome OS." HP has released a statement in response to the deal which talks about how Dell "faces an extended period of uncertainty and transition that will not be good for its customers." Perhaps they're right; HP is certainly familiar with such a situation. However, it's likely Dell is simply hoping to avoid the same struggles HP has faced over the past several years.

Tim O'Reilly Steps In To Debate Open Government and Linux 45

Posted by Soulskill
from the hope-the-repository-doesn't-go-down dept.
PatrickRIot writes "Aeon Magazine ran a longform critique of Open Source politics last week titled 'Open Sesame: "Openness" is the new magic word in politics – but should governments really be run like Wikipedia?' It referenced Tim O'Reilly and the man himself has stepped in at the bottom of the page for a detailed and lengthy rejoinder. 'I'm a bit surprised to learn that my ideas of "government as a platform" are descended from Eric Raymond's ideas about Linux, since: a) Eric is a noted libertarian with disdain for government b) Eric's focus on Linux was on its software development methodology. From the start, I was the open source activist focused on the power of platforms, arguing the role for the architecture of Unix and the Internet in powering the open source movement. ... One thing that distresses me about this discussion is the notion that somehow, if open government doesn't solve every problem, or creates new problems as it solves others, it is a failed movement. The world doesn't go forward in a straight line! The "open" democracy experiment of 1776 is still ongoing; we're trying to figure out how to use technology to adapt it to the 21st century and a country with a hundredfold greater population.'"

An anonymous reader writes "The hardware hasn't been released yet, but AMD has made available early open-source Linux GPU driver patches for supporting the future Radeon HD 8000 series graphics cards. At this time the Radeon HD 8800 'Oland' series is supported with the Mesa, DRM, X.Org, and kernel modifications. From the driver perspective, not many modifications are needed to build upon the Radeon HD 7000 series support."

UEFI Secure Boot Pre-Bootloader Rewritten To Boot All Linux Versions 185

Posted by timothy
from the next-level-reached dept.
hypnosec writes "The Linux Foundation's UEFI secure boot pre-bootloader is still in the works, and has been modified substantially so that it allows any Linux version to boot through UEFI secure boot. The reason for modifying the pre-bootloader was that the current version of the loader wouldn't work with Gummiboot, which was designed to boot kernels using BootServices->LoadImage(). Further, the original pre-bootloader had been written using 'PE/Coff link loading to defeat the secure boot checks.' As it stands, anything run by the original pre-bootloader must also be link-loaded to defeat secure boot, and Gummiboot, which is not a link-loader, didn't work in this scenario. This is the reason a re-write of the pre-bootloader was required and now it supports booting of all versions of Linux." Also in UEFI news: Linus Torvalds announced today that the flaw which was bricking some Samsung laptops if booted into Linux has been dealt with.

Linux: Booting Via UEFI Can Brick Samsung Notebooks 232

Posted by Unknown Lamer
from the like-openfirmware-only-it-sucks dept.
wehe writes "Heise News reports today some Samsung notebooks can be turned into a brick if booted just one time via UEFI into Linux. Even the firmware does not boot anymore. Some reports in the Ubuntu bug tracker system report that such notebooks can not be recovered without replacing the main board. Other Linux distributions may be affected as well. Kernel developers are discussing a change in the Samsung-laptop driver." It appears even Samsung is having trouble tracking down the problem (from the article): "According to Canonical's Steve Langasek, Samsung developers have been attempting to develop a firmware update to prevent the problem for several weeks. Langasek is advising users to start Ubuntu installation on Samsung notebooks from an up-to-date daily image, in which the Ubuntu development team has taken precautions to prevent the problem from arising. It is, however, not completely clear that these measures are sufficient."

Ask Slashdot: Open Source Remote Application Access? 113

from the over-there-but-over-here dept.
First time accepted submitter taikedz writes "Citrix Xenapp with Receiver/Metaframe allows publishing individual applications installed on a Windows server to users on remote machines. These applications open in their own windows, along side others as if they were installed locally. I am looking to do the same at home, with free software, publishing applications from Mac, Linux, and Windows machines (and yes, I've verified the license agreements for the apps I am going to do this with!). Up until now, the only alternatives I have found are full-on remote desktop login, not seamlessly-integrated. Can you recommend any tools that can achieve the goal of remote individual application access across platforms for free or at low-cost?"

New Secure Boot Patches Break Hibernation 196

Posted by Unknown Lamer
from the intentional-side-effects dept.
hypnosec writes "Matthew Garrett published some patches today which break hibernate and kexec support on Linux when Secure Boot is used. The reason for disabling hibernation is that currently the Linux kernel doesn't have the capability of verifying the resume image when returning from hibernation, which compromises the Secure Boot trust model. The reason for disabling the kexec support while running in Secure Boot is that the kernel execution mechanism may be used to load a modified kernel thus bypassing the trust model of Secure Boot." Before arming your tactical nuclear flame cannon, note that mjg says "These patches break functionality that people rely on without providing any functional equivalent, so I'm not suggesting that they be merged as-is." Support for signed kexec should come eventually, but it looks like hibernation will require some clever hacking to support properly in a Restricted Boot environment.

The bogosity meter just pegged.
