Alan Cox to NVIDIA: You Can't Use DMA-BUF 946

DMA-BUF is a recent kernel feature that allows multiple GPUs to quickly copy data into each others' framebuffers. A use case would be the NVIDIA Optimus that pairs a fast GPU with an Intel integrated GPU, where the NVIDIA GPU writes into the Intel framebuffer when it is active. But, NVIDIA won't be able to use this infrastructure because it's GPL. Alan Cox replied on LKML to a request from one of their engineers to mark the API non-GPL: "NAK. This needs at the very least the approval of all rights holders for the files concerned and all code exposed by this change. Also I'd note if you are trying to do this for the purpose of combining it with proprietary code then you are still in my view as a (and the view of many other) rights holder to the kernel likely to be in breach of the GPL requirements for a derivative work. You may consider that formal notification of my viewpoint. Your corporate legal team can explain to you why the fact you are now aware of my view is important to them." The rest of the thread is worth a read (a guy from RedHat agrees that this code is GPL and cannot become non-GPL without relicensing from a major subset of graphics system contributors). This has a ripple effect: it means that all of the ARM SoC GPU drivers can't use it either, and it may prevent any proprietary drivers for the proposed DRI version 3.

Red Hat Releases Preview Version of Open Stack Distribution 37

hypnosec writes "Red Hat has announced the availability of a preview version of its OpenStack Distribution that would enable it to compete with the likes of Amazon which is considered one of the leaders in infrastructure-as-a-service cloud services. The enterprise Linux maker was a late entrant into the OpenStack world where players like Rackspace, HP and Internap have already made their mark. Red Hat's OpenStack distribution enterprises can build and manage private, public, and hybrid infrastructure-as-a-service clouds. These companies will not only be competing with the likes of Amazon, but will also be competing against themselves to get a bite out of the IaaS cloud. What started as a project has quickly developed into an open source solution that enables organizations to achieve performance, features and greater functionality from their private and/or public clouds. The announcement of OpenStack Foundation acted as a catalyst toward the fast-paced development of the platform."

Ubuntu Unity Ported To Fedora Using OpenSUSE 128

sfcrazy writes "The general tendency within the open source community is to a whole new wheel to push your own cart. A majority of open source projects are suffering from duplication. Luckily, we just noticed a great example of such collaboration (or using resources by different competing projects) within the distro community. Ubuntu's popular Unity shell is being ported to Fedora (the distro which leads the development of Gnome shell and its also the breeding ground of many latest technologies which are used by the rest of the GNU/Linux world). Interestingly developers users openSUSE's build service to create this port. openSUSE leads the development of Gnome and KDE along with LibreOffice." Calling Unity "popular" seems like a stretch, but it's certainly where a lot of Ubuntu work has been lavished; the cooperation that open source code fosters at least lets whoever wants to use or develop it do so.

The Leap Second Is Here! Are Your Systems Ready? 284

Tmack writes "The last time we had a leap second, sysadmins were taken a bit by surprise when a random smattering of systems locked up (including Slashdot itself) due to a kernel bug causing a race condition specific to the way leap seconds are handled/notified by ntp. The vulnerable kernel versions (prior to 2.6.29) are still common amongst older versions of popular distributions (Debian Lenny, RHEL/CentOS 5) and embedded/black-box style appliances (Switches, load balancers, spam filters/email gateways, NAS devices, etc). Several vendors have released patches and bulletins about the possibility of a repeat of last time. Are you/your team/company ready? Are you upgraded, or are you going to bypass this by simply turning off NTP for the weekend?" Update: 07/01 03:14 GMT by S : ZeroPaid reports that this issue took down the Pirate Bay for a few hours.

How Red Hat Decides Which Open Source Companies To Buy 20

darthcamaro writes "You don't really buy an open source company — since the tech is all open. But then again, Red Hat 'buys' open source companies all the time, they just bought one this week. So when does it makes sense for Red Hat to buy a company versus just building it on their own? Apparently, it all comes down to community. 'When you buy an open source company, if the people aren't coming and passionate about staying then you spend a lot of money for what? Because you don't get a lot of intellectual property,' Red Hat CEO Jim Whitehurst said."

Red Hat Clarifies Doubts Over UEFI Secure Boot Solution 437

sfcrazy writes "Red Hat's Tim Burke has clarified Fedora/Red Hat's solution to Microsoft's secure boot implementation. He said, 'Some conspiracy theorists bristle at the thought of Red Hat and other Linux distributions using a Microsoft initiated key registration scheme. Suffice it to say that Red Hat would not have endorsed this model if we were not comfortable that it is a good-faith initiative.'" Color me unimpressed, and certainly concerned: "A healthy dynamic of the Linux open source development model is the ability to roll-your-own. For example, users take Fedora and rebuild custom variants to meet personal interest or experiment in new innovations. Such creative individuals can also participate by simply enrolling in the $99 one time fee to license UEFI. For users performing local customization, they will have the ability to self-register their own trusted keys on their own systems at no cost." From what I can tell, the worst fears of the trusted computing initiative are coming true despite any justifications from Red Hat here. Note that the ability to install your owns keys is certainly not a guaranteed right.

Red Hat Will Pay Microsoft To Get Past UEFI Restrictions 809

ToriaUru writes "Fedora is going to pay Microsoft to let them distribute a PC operating system. Microsoft is about to move from effectively owning the PC hardware platform to literally owning it. Once Windows 8 is released, hardware manufacturers will be forced to ship machines that refuse to run any software that is not explicitly approved by Microsoft — and that includes competing operating systems like Linux. Technically Fedora didn't have to go down this path. But, as this article explains, they are between a rock and a hard place: if they didn't pay Microsoft to let them onto the PC platform, they would have to explain to their potential users how to mess with firmware settings just to install the OS. How long before circumventing the secure boot mechanism is considered a DMCA violation and a felony?" Note that the author says this is likely, but that the entire plan is not yet "set in stone."

Fedora 17 Released 141

ekimd writes "Fedora 17 aka "Beefy Miracle" is released. Some of the major features include: ext4 with >16TB filesystems, dynamic firewall configuration, automatic multi-seat, and more. Major software updates include Gnome 3.4, GIMP 2.8, and GCC 4.7. The full feature list can be found here. Personally, I still find Gnome 3 to be an 'unholy mess' so I'm loving XFCE with Openbox."

In Your Face, Critics! Red Hat Passes $1 Billion In Revenue 227

head_dunce writes "Now that Red Hat has officially posted more than a billion dollars in revenue, ($1.13 billion to be exact), the company's PR department sent this funny list of quotes predicting doom. For instance, 'We think of Linux as a competitor in the student and hobbyist market but I really don't think in the commercial market we'll see it in any significant way.' Bill Gates, 2001."

Tom's Hardware Tests and Reviews Fedora 16 and Gnome 3 101

New submitter LordDCLXVI writes with a review at Tom's Hardware that starts out with some loaded questions about GNOME 3, as included in the newest version of Red Hat's Fedora: "While most other distros are passing up or postponing GNOME Shell, Fedora is full steam ahead. Does Red Hat know something the rest of us don't? Or is GNOME 3 really as bad as everyone says?" Writes LordDCLVXI: "This massive article amounts to a full-blown guide to Fedora 16 'Verne' and complete dissection of GNOME Shell. It begins with an installation guide, with instructions for enabling third-party repos, proprietary graphics drivers, Wi-Fi, Flash, Java, multimedia codecs, and 32-bit libs. Next up is a GNOME Shell tear-down, including customization options and methods to 'fix' the Shell or mimic GNOME 2. Finally, Fedora is benchmarked against Ubuntu 11.10 and Windows 7. [While the author] adds to the voices criticizing GNOME Shell, he also points out that the extensions can empower distributors to create unique, yet compatible layouts. One of the most fair and constructive critiques of GNOME 3 — definitely worth the read, and even makes GNOME 3 worth a second look."

Red Hat Appoints Robyn Bergeron First Female Fedora Project Leader 146

darthcamaro writes "Red Hat is changing the leadership at the Fedora Project. Jared Smith is out after having been the Fedora Project Leader since June of 2010. In is Robyn Bergeron — who will be the first female leader of the open source project's history. Bergeron is well known in the community as she has most recently been the Fedora Program Manager."

Linux-Powered Christmas Display Puts Rudolph To Shame 68

xmas2003 writes "Over at Linux.com, Zonker writes about Alek's Controllable Christmas Lights for Celiac Disease. This annual Internet tradition uses a hi/low-tech combo of LAMP'ed Redhat Web Servers, a 7+ year old Thinkpad running Ubuntu for the X10 control, and an old-school webpage design that could be politely described as Web 0.0 — wait until you see the animated cursor — D'OH! The site is free (and totally fun) as it also raises awareness and donations for Celiac Disease — over $70,000 to the University of Maryland. Nifty pictures of the crazy christmas display can be seen on the Christmas Blog (notice Clifford Stoll's The Cuckoo's Egg in post #220) plus watch videos of it in action with comedic history. Nothing quite says Christmas like a giant, inflatable HULK wearing a Santa Hat... along with three wise men of Elmo, SpongeBob, and Homer Simpson. The Slashdot Effect of turning 21,000 Christmas lights ON & OFF this evening should provide quite a Christmas Eve show to Alek's neighbors... and also the International Space Station."

Red Hat's Linux Changes Raise New Questions 433

itwbennett writes "Last month two Red Hat developers proposed to replace the 30-year-old syslog system with a new Journal daemon. Initial reaction was mostly negative and 'focused on the Journal's use of a binary key-value form of data to log system events,' says blogger Brian Proffit. But now, says Proffitt, it seems that the proposal to replace syslog has less to do with the fixing syslog's problems than with Red Hat's desire to go its own way with Linux infrastructure."

Tool Kills Hidden Linux Bugs, Vulnerabilities 47

mask.of.sanity writes with this excerpt from SC Magazine: "Australian researcher Silvio Cesare has released a tool capable of automatically detecting bugs and vulnerabilities in embedded Linux libraries. The script correlates vulnerability advisory CVEs for third-party libraries to determine if holes have carried over to Linux platforms or have not been patched. Such holes often escape the eye of developers because the libraries may not be kept updated with sources. This is further compounded because vulnerabilities in cross distributed packages can leave Linux platforms vulnerable."

GNOME Shell No Longer Requires GPU Acceleration 237

An anonymous reader writes "The GNOME 3.0 Shell with the Mutter window manager no longer requires GPU acceleration to work, while still retaining the compositing window manager and OpenGL support. GNOME Shell can now work entirely on the CPU using the LLVM compiler via the Gallium3D LLVMpipe driver. This will be another change to Fedora 17 to no longer depend upon the GNOME3 fall-back, which is expected to eventually be deprecated and further anger GNOME2 fans."

Fedora Aims To Simplify Linux Filesystem 803

jfruhlinger writes "Even Linux's most passionate partisans will admit that its filesystem, which stashes vital files in a variety of arcane directories, can be baffling to users. The developers at the Fedora project want to cut the Gordian knot and consolidate all executables into /usr/bin and all libraries into /usr/lib or /usr/lib64. One downside: this system would conflict with the standards developed by the Linux Standard Base, or the (rarely used) Filesystem Hierarchy Standard."

How Can I Justify Using Red Hat When CentOS Exists? 666

Bocaj writes "I recently spec'd out a large project for our company that included software from Red Hat. It came back from the CIO with everything approved except I have to use CentOS. Why? Because 'it's free Red Hat.' Personally I really like the CentOS project because it puts enterprise class software in the hands of people who might not otherwise afford it. We are not those people. We have money. In fact, I questioned the decision by asking why the CIO was willing to spend money on another very similar project and not this one. The answer was 'because there is no free alternative.' I know this has come up before and I don't want to beat a dead horse, but this is still a very persistent issue. Our CIO is convinced that technical support for any product is worthless. He's willing to spend money on 'one-time' software purchases, but nothing that is an annual subscription. There is data to support that the Red Hat subscription is cheaper that many other up-front paid software products but not CentOS. The only thing it lacks is support, which the CIO doesn't want. Help?"
