  • The final step for huge-page swapping

    For many years, Linux system administrators have gone out of their way to avoid swapping. The advent of nonvolatile memory is changing the equation, though, and swapping is starting to look interesting again — if it can perform well enough. That is not the case in current kernels, but a longstanding project to allow the swapping of transparent huge pages promises to improve that situation considerably. That work is reaching its final stage and might just enter the mainline soon.

    The use of huge pages can improve the performance of the system significantly, so the kernel works hard to make them available. The transparent huge pages mechanism collects application data into huge pages behind the scenes, and the memory-management subsystem as a whole works hard to ensure that appropriately sized pages are available. When it comes time to swap out a process's pages, though, all of that work is discarded, and a huge page is split back into hundreds of normal pages to be written out. When swapping was slow and generally avoided, that didn't matter much, but it is a bigger problem if one wants to swap to a fast device and maintain performance.

  • Revisiting the MAP_SHARED_VALIDATE hack

    One of the the most commonly repeated mistakes in system-call design is a failure to check for unknown flags wherever flags are accepted. If there is ever a point where callers can get away with setting unknown flags, then adding new flags becomes a hazardous act. In the case of mmap(), though, developers found a clever way around this problem. A recent discussion has briefly called that approach into question, though, and raised the issue of what constitutes a kernel regression. No changes are forthcoming as a result, but the discussion does provide an opportunity to look at both the specific hack and how the kernel community decides whether a change is a regression or not.

    Back in 2017, several developers were trying to figure out a way to safely allow direct user-space access to files stored on nonvolatile memory devices. The hardware allows this memory to be addressed directly by the processor, but any changes could go astray if the filesystem were to move blocks around at the same time. The solution that arose was a new mmap() flag called MAP_SYNC. When a file is mapped with this flag set (and the file is stored on a nonvolatile memory device), the kernel will take extra care to ensure that access to the mapping and filesystem-level changes will not conflict with each other. As far as applications are concerned, using this flag solves the problem.

  • Fedora 29 Dropping GCC From Their Default Build Root Has Been Causing A Heated Debate

    One of the surprisingly controversial changes being implemented for Fedora 29 is dropping GCC and GCC-C++ from the default BuildRoot for assembling Fedora packages with Koji and Mock.

    Up to now it's always just been implied that GCC (including the GCC C++ compiler) is there by default with every build-root. But these days with more packages being written in languages like Go, Rust, Python, Node.js, and other modern languages, the proportion of C/C++ applications is decreasing. As such, the GCC C/C++ support is no longer being implied with the default build environments in Koji/Mock, which in turn should help package build times for non-C/C++ packages as they will no longer need to pull in the gcc/gcc-c++ packages and in turn a cleaner buildroot environment too.

  • Open Source GraphQL Engine Launched

    An open source GraphQL Engine has been launched that can be used with applications based on Postgres without the need for backend GraphQL processing code.

    The new GraphQL as a service can be used by front-end developers to build scaleable GraphQL apps on Postgres.

    Hasura’s GraphQL Engine automates the implementation and linking of databases to the graph. The APIs can be used to choose tables from new or existing database for use with GraphQL and link those existing tables into a graph. The engine has built-in authorization and authentication with granular authentication and a dynamic access control system that integrates with existing authentication systems such as Auth0 or custom implementations. The engine is also lightweight, consuming only 50MB of RAM even while serving more than a thousand requests per second.

  • Event management with Indico

    There are many things to love about the Linux Plumbers Conference (LPC), but the event's web site has not often been considered one of them. This year, your editor took on the task of finding a new system to handle proposal submission, review, and scheduling, despite his own poor track record when it comes to creating attractive web sites. The search finally settled on a system called Indico; read on for some impressions of this interesting free event-management system.

    There are a number of free systems out there for handling the needs of conferences. Among the others that were considered are Symposion, which is used by linux.conf.au, and OSEM, the openSUSE event-management system. Both are capable systems, but neither seems to have been developed with the idea that others might want to pick it up and run it. In particular, every Symposion installation seems to require a fair amount of low-level customization. The installation documentation for both is, to put it charitably, a bit scant. Indico, instead, comes with a nice installation manual that makes the task something that is, if not actually easy, at least achievable without having to actually learn the entire code base first. 

    [...]

     Events in Indico have most of the features needed to track their life cycle. Each event has a home page with a reasonable degree of customization; pages of information can be attached to the home page. There is an elaborate mechanism for proposal submission and review. Events can be split into tracks and sessions, with a different coordinator for each session; the schedule for the whole thing can be managed in a reasonably straightforward way. For those who need it, Indico also offers a registration system, though LPC is not using it.

  • An Invisible Tax on the Web: Video Codecs

    Here’s a surprising fact: It costs money to watch video online, even on free sites like YouTube. That’s because about 4 in 5 videos on the web today rely on a patented technology called the H.264 video codec.

    A codec is a piece of software that lets engineers shrink large media files and transmit them quickly over the internet. In browsers, codecs decode video files so we can play them on our phones, tablets, computers, and TVs. As web users, we take this performance for granted. But the truth is, companies pay millions of dollars in licensing fees to bring us free video.

    It took years for companies to put this complex, global set of legal and business agreements in place, so H.264 web video works everywhere. Now, as the industry shifts to using more efficient video codecs, those businesses are picking and choosing which next-generation technologies they will support. The fragmentation in the market is raising concerns about whether our favorite web past-time, watching videos, will continue to be accessible and affordable to all.

  • ARM Takes Down Boneheaded Website Attacking Open-Source Rival

    ARM, the incredibly successful developer of CPU designs, appears to be getting a little nervous about an open-source rival that’s gaining traction. At the end of June, ARM launched a website outlining why it’s better than its competitor’s offerings and it quickly blew up in its face. Realizing the site was a bad look, ARM has now taken it down.

    For the uninitiated, ARM Holdings designs various architectures and cores that it licenses to major chipmakers around the world. Its tech can be found in over 100 billion chips manufactured by huge names like Apple and Nvidia as well as many other lesser-known players in the low-power market. If ARM is Windows, you can think of RISC-V as an early Linux. Like ARM, it’s an architecture based on reduced instruction set computing (RISC), but it’s free to use and open to anyone to contribute or modify. While ARM has been around since 1991, RISC-V just got started in 2010 but it’s gaining a lot of ground and ARM’s pitiful website could easily be seen as a legitimizing moment for the tech.

  • A Landmark Legal Shift Opens Pandora’s Box for DIY Guns

     

    Two months ago, the Department of Justice quietly offered Wilson a settlement to end a lawsuit he and a group of co-plaintiffs have pursued since 2015 against the United States government. Wilson and his team of lawyers focused their legal argument on a free speech claim: They pointed out that by forbidding Wilson from posting his 3-D-printable data, the State Department was not only violating his right to bear arms but his right to freely share information. By blurring the line between a gun and a digital file, Wilson had also successfully blurred the lines between the Second Amendment and the First.

     

    "If code is speech, the constitutional contradictions are evident," Wilson explained to WIRED when he first launched the lawsuit in 2015. "So what if this code is a gun?”

  • Kindness and open-source projects

    Brett Cannon is a longtime Python core developer and member of the open-source community. He got to check off one of his bucket-list items when he gave a keynote [YouTube video] at PyCon 2018. That keynote was a rather personal look at what he sees as some problem areas in the expectations of the users of open-source software with respect to those who produce it. While there is lots to be happy for in the open-source world, there are some sharp edges (and worse) that need filing down.

    He started with his background as a way to show that he has the experience to give this talk. He is the development lead on the Python extension for Visual Studio Code, which is Microsoft's cross-platform open-source code editor. He noted that the two qualifiers for the editor are probably shocking to some. It was originally a community open-source project; Microsoft hired the developer behind it and it is now "corporate open source", Cannon said. That means there is a company backstopping the project; if the community fell away, the project would continue.

    He has been a Python core developer since April 2003; he got the commit bit shortly after attending the first PyCon (and he has attended every PyCon since as well). In contrast, Python is community open source; if the community disappeared, the project "would probably collapse within a month". He has contributed to over 80 open-source projects along the way; many of those were simply typo fixes of various sorts, but it has given him exposure to a lot of different development processes. "I've been lucky enough to have a broad range of exposure to open source overall."

  • Python and the web

    Dan Callahan is a developer advocate at Mozilla and no stranger to PyCon (we covered a talk of his at PyCon 2013). He was also the champion at Mozilla for the grant that helped revamp the Python Package Index (PyPI). At PyCon 2018, he gave a keynote talk [YouTube video] that focused on platforms of various sorts—and where Python fits into the platforms of the future.

    He began with a slide showing the IBM PCjr, which was the first computer IBM made for the home market. It was released in 1984 and immediately drew a bad reaction from the public and the press (Time magazine called it "one of the biggest flops in the history of computing"). Commercially and even objectively, the PCjr was a bad platform, he said.

    But when he was old enough to become interested in computers, that was the computer that was available to him—his father had bought one during the roughly one year they were available. He learned BASIC as his first language because the PCjr came with BASIC. He didn't think about it at the time, but his first language was chosen for him; he didn't get to consider what features he wanted or how the language's community was. His platform had determined the tool he would use.

    Fast-forward a few years to when he was in high school and had his own computer; even though he had access to Linux, PHP, and Perl, he still found himself programming in BASIC. This was the pre-smartphone era, so when he was bored in class, he had to find some other way to distract himself; he and his friends turned to TI-82 graphing calculators. Those were programmable in BASIC, so even though he had more sophisticated tools available to him, if he wanted to share something with his friends, it would have to be written in BASIC for the TI-82. That platform also dictated the tool that he would use.

  • ​The return of Spectre

    The return of Spectre sounds like the next James Bond movie, but it's really the discovery of two new Spectre-style CPU attacks.

    Vladimir Kiriansky, a Ph.D. candidate at MIT, and independent researcher Carl Waldspurger found the latest two security holes. They have since published a MIT paper, Speculative Buffer Overflows: Attacks and Defenses, which go over these bugs in great detail. Together, these problems are called "speculative execution side-channel attacks."

    These discoveries can't really come as a surprise. Spectre and Meltdown are a new class of security holes. They're deeply embedded in the fundamental design of recent generations of processors. To go faster, modern chips use a combination of pipelining, out-of-order execution, branch prediction, and speculative execution to run the next branch of a program before it's called on. This way, no time is wasted if your application goes down that path. Unfortunately, Spectre and Meltdown has shown the chip makers' implementations used to maximize performance have fundamental security flaws.

    Denuvo is... look, just go read this trove of backlinks, because I've written far too many of these intros to be able to come up with one that is even remotely original. Rather than plagiarize myself, let me just assume that most of you know that Denuvo is a DRM that was once thought to be invincible but has since been broken in every iteration developed, with cracking times often now down to days and hours rather than weeks or months. Key in this post is that much if not most of the work cracking Denuvo has been done by a single person going by the handle Voksi. Voksi is notable not only for their nearly singlehandedly torpedoing the once-daunting Denuvo DRM, but also for their devotion to the gaming industry and developers that do things the right way, even going so far as to help them succeed.

  • Chrome 67 to Counter Spectre on Mac, Windows, Linux, Chrome OS via Site Isolation

    The Spectre and Meltdown vulnerabilities, discovered earlier this year, caught everyone off guard including hardware and software companies. Since then, several vendors have patched them, and today, Google Chrome implemented measures to protect the browser against Spectre. The exploit uses the a feature found in most CPUs to access parts of memory that should be off-limits to a piece of code and potentially discover the values stored in that memory. Effectively, this means that untrustworthy code may be able to read any memory in its process’s address space. In theory, a website could use such an attack to steal information from other websites via malicious JavaScript code. Google Chrome is implementing a technique known as site isolation to prevent any future Spectre-based attacks from leaking data.

Hiding the Fedora boot menu

Filed under
Red Hat

The venerable Linux boot menu has made its appearance at boot time since the days when LILO was the standard boot loader, through the days of GRUB, and onward to today's GRUB 2 and others. It is sometimes configured out by distributions as something that will potentially confuse less-technical users, but it has been a mainstay of Fedora for many releases. A recent proposal to hide the menu, starting in Fedora 29, has met a mixed reaction, but those who are not in favor are also those most able to revert to the existing behavior.

Hans de Goede raised the issue back at the end of May. He suggested that Fedora had at one time hidden the boot menu, but changed. As a longtime Fedora user, I don't remember that switch, but my memory is faulty and that may be the case here. In any case, De Goede's idea is to not have the distribution print any confusing messages at boot time: "the end goal being a user pressing the on button and then going to the graphical login manager without him seeing any text messages / menus filled with technical jargon."

The response was somewhat mixed, as might be expected. Stephen Gallagher was concerned about boots that failed and gave the user no alternatives to try. De Goede said that the plan was to detect failed boots and then show the boot menu on the next boot. He muddied the waters somewhat by mentioning a "fastboot" feature that he is planning for Fedora 30. It would effectively provide no way for a user sitting at the console to override the boot sequence (with a key press, say) and get the boot menu once the system has started booting.

On Indiegogo, Network Sorcery is pitching “UCAN” software for a CAN-equipped Raspberry Pi board that enables passive, real-time decoding of automotive telematics data over the CAN Bus. UCAN initially supports GM, Infiniti, and Nissan cars.

San Diego based Network Sorcery, which publishes information about network communication protocols, including the RFC Sourcebook, has gone to Indiegogo to launch a telematics program that runs on a Raspberry Pi 3 equipped with a CAN adapter board. The Linux-based UCAN software passively extracts and decodes telematics data in real time via the CAN Bus, offering “more detail and up to 50 times the volume of data than OBD2 (or OBD-II) based systems can provide,” says Network Sorcery.

Oracle reckons Linux remote direct memory access (RDMA) implementations need features like high availability and load balancing, and hopes to sling code into the kernel to do exactly that.

The problem, as Oracle Linux kernel developer Sudhakar Dindukurti explained in this post, is that performance and security considerations mean RDMA adapters tie hardware to a “specific port and path”.

A standard network interface card, on the other hand, can choose which netdev (network device) to use to send a packet. Failover and load balancing is native.
