Linux APIC Code Prepares For A Major Overhaul

Filed under
Linux

The x86 APIC subsystem within the Linux kernel is beginning the process of a major overhaul with the Linux 3.17 kernel.

The Advanced Programmable Interrupt Controller (APIC) support is being overhauled to support physical IOAPIC hot-plugging. Within the Linux 3.17 kernel this feature isn't present but the prepatory work is moving forward after a first attempt at the hot-plug support was rejected on technical grounds. In prepping for the APIC hot-plug support, obsolete driver abstractions were removed and other changes made for this merge window.

Those concerned about the Linux APIC code can find out more about the forthcoming changes via this lengthy mailing list message.

9 Signs You Should Use Linux on Your Computer

Filed under
GNU
Linux

you may know Linux operating systems are in the vast majority of cases completely free, and not just free in the sense that you don't have to pay anything, but also in the sense that you're free to legally copy it as many times as you want and share with anyone. What's called illegal piracy in the Windows world pretty much doesn't exist in the Linux world. That's the nature of open source software licensing.

This can lead to money savings because you don't have to buy Windows upgrades to run it legally, and if you're upgrading multiple systems (family, business, etc.) this can add up.

Yet despite being free the quality is surprisingly good. Big companies like Canonical, RedHat, Novell, Google and so on are funding its development and making money on related support services they offer their business users. The model is shown to work. You may not be foreign to open source software if you've used popular programs like Chrome, Firefox, VLC, and many others, all of which are open source, like Linux.

The Connected Car, Part 2: Wired For Wireless - It's All Business

Filed under
Linux

The connected car is a battlefield among technology purveyors fighting to get their hardware plugged into the vehicle's network bus. Open source technology is becoming a key contender. OEMs are sorting through a garage full of options from versions of embedded Linux to the Automotive Grade Linux (AGL) distro and the Android car platform.

The connected car concept is picking up speed as a vehicle intelligence system in its own right. It is turning the common car into a fully functional communications center on wheels. Its abilities reach far beyond mere infotainment.

12 Linux-Based Home Automation Systems for Under $300

Filed under
Linux

Home automation hubs have emerged as the tech startup product of choice in 2014, and most run on embedded Linux. The category has been re-energized with the dropping costs of wireless radios and embedded processors, as well as the ubiquity of readymade touchscreen interfaces in the form of Android and iOS devices. This slide show presentation covers 10 Linux-based and two Android-based home automation systems starting at under $300.

Home automation systems have been around for more than a decade, but were usually affordable only to a few. Early Linux-based products include the circa-2002 CorAccess Companion, as well as later tuxified products from Control4, such as the Control4 Home Controller HC-500. While the HC-500's $1,500 was a price breakthrough back in 2008, Control4's entry level system is now an HC-250 model selling for under $500 plus licensing. You'll find most of the systems listed here starting at under $200, with some hubs selling for as little as $49. Of course, you'll likely spend much more than that on compatible smart devices, and equipping a large home could easily push you over the $1,000 mark.

FiveNinjas has launched a “Slice” media player on Kickstarter based on the Raspberry Pi Compute Module, with a 1TB HDD and a customized version of XBMC.

UK-based startup FiveNinjas developed the Slice because the developers found it annoying when their media players became useless when carried beyond an Internet connection. Unlike most media players, the Slice ships with a 1TB hard disk drive for storing plenty of video for offine playback.

XFS Introduces A Sysfs Interface With Linux 3.17

Filed under
Linux

The latest noteworthy pull request worth covering for the Linux 3.17 kernel merge window is of the XFS file-system updates.

Dave Chinner sent in the XFS pull request for Linux 3.17 on Tuesday. The changes this time around aren't anything jaw-dropping but just another minor step forward for this file-system competing with EXT4 and Btrfs. Perhaps the most notable change this time around is the introduction of a sysfs interface to the file-system. Below is Chinner's highlights for XFS on Linux 3.17.

As popular as the iPad has been for end consumers, schools have also been a major part of the tablet’s success. Ever since Apple launched the iPad in 2010, schools all over the country have experimented with placing them in classrooms or giving them to students to bring home with them. The Atlantic reports that although many institutions were initially satisfied with the results, many are now beginning to see the potential upshot of affordable laptops over expensive tablets.

Events: FOSDEM Samba Talks, USENIX Enigma, LCA (linux.conf.au) and FAST18

  • Authentication and authorization in Samba 4
    Volker Lendecke is one of the first contributors to Samba, having submitted his first patches in 1994. In addition to developing other important file-sharing tools, he's heavily involved in development of the winbind service, which is implemented in winbindd. Although the core Active Directory (AD) domain controller (DC) code was written by his colleague Stefan Metzmacher, winbind is a crucial component of Samba's AD functionality. In his information-packed talk at FOSDEM 2018, Lendecke said he aimed to give a high-level overview of what AD and Samba authentication is, and in particular the communication pathways and trust relationships between the parts of Samba that authenticate a Samba user in an AD environment.
  • Two FOSDEM talks on Samba 4
    Much as some of us would love never to have to deal with Windows, it exists. It wants to authenticate its users and share resources like files and printers over the network. Although many enterprises use Microsoft tools to do this, there is a free alternative, in the form of Samba. While Samba 3 has been happily providing authentication along with file and print sharing to Windows clients for many years, the Microsoft world has been slowly moving toward Active Directory (AD). Meanwhile, Samba 4, which adds a free reimplementation of AD on Linux, has been increasingly ready for deployment. Three short talks at FOSDEM 2018 provided three different views of Samba 4, also known as Samba-AD, and left behind a pretty clear picture that Samba 4 is truly ready for use. I will cover the first two talks in this article, and the third in a later one.
  • A report from the Enigma conference
    The 2018 USENIX Enigma conference was held for the third time in January. Among many interesting talks, three presentations dealing with human security behaviors stood out. This article covers the key messages of these talks, namely the finding that humans are social in their security behaviors: their decision to adopt a good security practice is hardly ever an isolated decision. Security conferences tend to be dominated by security researchers demonstrating their latest exploits. The talks are attack-oriented, they keep a narrow focus, and usually they close with a dark outlook. The security industry has been doing security conferences like this for twenty years and seems to prefer this format. Yet, if you are tired of this style, the annual USENIX Enigma conference is a welcome change of pace. Most of the talks are defense-oriented, they have a horizon going far beyond technology alone, and they are generally focused on successful solutions.
  • DIY biology
    A scientist with a rather unusual name, Meow-Ludo Meow-Meow, gave a talk at linux.conf.au 2018 about the current trends in "do it yourself" (DIY) biology or "biohacking". He is perhaps most famous for being prosecuted for implanting an Opal card RFID chip into his hand; the Opal card is used for public transportation fares in Sydney. He gave more details about his implant as well as describing some other biohacking projects in an engaging presentation. Meow-Meow is a politician with the Australian Science Party, he said by way of introduction; he has run in the last two elections. He founded BioFoundry, which is "Australia's first open-access molecular biology lab"; there are now two such labs in the country. He is also speaks frequently as "an emerging technology evangelist" for biology as well as other topics.
  • Notes from FAST18

    I attended the technical sessions of Usenix's File And Storage Technology conference this week. Below the fold, notes on the papers that caught my attention.

Security: Vista10 and uTorrent Holes Found by Google

  • Google drops new Edge zero-day as Microsoft misses 90-day deadline

    Google originally shared details of the flaw with Microsoft on 17 November 2017, but Microsoft wasn’t able to come up with a patch within Google’s non-negotiable “you have 90 days to do this” period.

  • Google Goes Public with Another Major Windows 10 Bug
    After revealing an Edge browser vulnerability that Microsoft failed to fix, Google is now back with another disclosure, this time aimed at Windows 10 Fall Creators Update (version 1709), but potentially affecting other Windows versions as well. James Forshaw, a security researcher that’s part of Google’s Project Zero program, says the elevation of privilege vulnerability can be exploited because of the way the operating system handles calls to Advanced Local Procedure Call (ALPC). This means a standard user could obtain administrator privileges on a Windows 10 computer, which in the case of an attack, could eventually lead to full control over the impacted system. But as Neowin noted, this is the second bug discovered in the same function, and both of them, labeled as 1427 and 1428, were reported to Microsoft on November 10, 2017. Microsoft said it fixed them with the release of the February 2018 Patch Tuesday updates, yet as it turns out, only issue 1427 was addressed.
  • uTorrent bugs let websites control your computer and steal your downloads

    The vulnerabilities, according to Project Zero, make it possible for any website a user visits to control key functions in both the uTorrent desktop app for Windows and in uTorrent Web, an alternative to desktop BitTorrent apps that uses a web interface and is controlled by a browser. The biggest threat is posed by malicious sites that could exploit the flaw to download malicious code into the Windows startup folder, where it will be automatically run the next time the computer boots up. Any site a user visits can also access downloaded files and browse download histories.

  • BitTorrent Client uTorrent Suffers Security Vulnerability (Updated)

    BitTorrent client uTorrent is suffering from an as yet undisclosed vulnerability. The security flaw was discovered by Google security researcher Tavis Ormandy, who previously said he would reveal a series of "remote code execution flaws" in torrent clients. BitTorrent Inc. has rolled out a 'patch' in the latest Beta release and hopes to fix the stable uTorrent client later this week.
