  • Steps toward a privacy-preserving phone

    What kind of cell phone would emerge from a concerted effort to design privacy in from the beginning, using free software as much as possible? Some answers are provided by a crowdfunding campaign launched in August by Purism SPC, which has used two such campaigns successfully in the past to build a business around secure laptops. The Librem 5, with a five-inch screen and radio chip for communicating with cell phone companies, represents Purism's hope to bring the same privacy-enhancing vision to the mobile space, which is much more demanding in its threats, technology components, and user experience.

    The abuse of mobile phone data has become a matter of worldwide concern. The capture and sale of personal data by apps is so notorious that it has been covered in USA Today; concerns over snooping contribute to the appeal of WhatsApp (which has topped 1.3 billion users) and other encrypted and privacy-conscious apps. But apps are only one attack vector. I got in touch with Todd Weaver, founder and CEO of Purism, to find out what the company is doing to plug the leaks in mobile devices.

  • DockerCon EU 17 Panel Debates Docker Container Security

    There are many different security capabilities that are part of the Docker container platform, and there are a number of vendors providing container security offerings. At the DockerCon EU 17 conference in Copenhagen, Denmark, eWEEK moderated a panel of leading vendors—Docker, Hewlett Packard Enterprise, Aqua Security, Twistlock and StackRox—to discuss the state of the market.

    To date, there have been no publicly disclosed data breaches attributed to container usage or flaws. However, that doesn't mean that organizations using containers have not been attacked. In fact, Wei Lien Dang, product manager at StackRox, said one of his firm's financial services customers did have a container-related security incident.

  • DockerCon EU: Tips and Tools for Running Container Workloads on AWS

    Amazon Web Services wants to be a welcome home for developers and organizations looking to deploy containers. At the DockerCon EU conference here, a pair of AWS technical evangelists shared their wisdom on the best ways to benefit from container deployments.

    The terms microservices and containers are often used interchangeably by people. Abby Fuller, technical evangelist at AWS, provided the definition of microservices coined by Adrian Crockford, VP of Cloud Architecture at AWS and formerly the cloud architect at Netflix.

    Steve Singh has ambitious plans for Docker Inc. that are nothing less than transforming the world of legacy applications into a modern cloud-native approach.

    Singh was named CEO of Docker on May 2 and hosted his first DockerCon event here Oct. 16-19. The highlight of DockerCon EU was the surprise announcement that Docker is going to support the rival open-source Kubernetes container orchestration system.

    In a video interview with eWEEK, Singh explained the rationale behind the Kubernetes support and provided insight into his vision for the company he now leads.

  • MongoDB's IPO Beats the Market Out of the Gate

    The folks at MongoDB raised a whole lot of money today in their debut on NASDAQ.

    Yesterday the open source company announced it was going to be asking $24 a share for the 8 million Class A shares it was letting loose in its IPO, which had some Wall Street investors scratching their heads and wondering if the brains at Mongo were suffering from some kind of undiagnosed damage. Analysts had been estimating an opening price of between $20-22 per share, and on October 6 the company had estimated an opening price in the range of $18-20.

LWN on Linux: LTS, API, Pointer Leaks and Linux Plumbers Conference (LPC)

Filed under
Linux
  • Cramming features into LTS kernel releases

    While the 4.14 development cycle has not been the busiest ever (12,500 changesets merged as of this writing, slightly more than 4.13 at this stage of the cycle), it has been seen as a rougher experience than its predecessors. There are all kinds of reasons why one cycle might be smoother than another, but it is not unreasonable to wonder whether the fact that 4.14 is a long-term support (LTS) release has affected how this cycle has gone. Indeed, when he released 4.14-rc3, Linus Torvalds complained that this cycle was more painful than most, and suggested that the long-term support status may be a part of the problem. A couple of recent pulls into the mainline highlight the pressures that, increasingly, apply to LTS releases.

    As was discussed in this article, the 4.14 kernel will include some changes to the kernel timer API aimed at making it more efficient, more like contemporary in-kernel APIs, and easier to harden. While API changes are normally confined to the merge window, this change was pulled into the mainline for the 4.14-rc3 release. The late merge has led to a small amount of grumbling in the community.

  • Improving the kernel timers API

    The kernel's timer interface has been around for a long time, and its API shows it. Beyond a lack of conformance with current in-kernel interface patterns, the timer API is not as efficient as it could be and stands in the way of ongoing kernel-hardening efforts. A late addition to the 4.14 kernel paves the way toward a wholesale change of this API to address these problems.

  • What's the best way to prevent kernel pointer leaks?

    An attacker who seeks to compromise a running kernel by overwriting kernel data structures or forcing a jump to specific kernel code must, in either case, have some idea of where the target objects are in memory. Techniques like kernel address-space layout randomization have been created in the hope of denying that knowledge, but that effort is wasted if the kernel leaks information about where it has been placed in memory. Developers have been plugging pointer leaks for years but, as a recent discussion shows, there is still some disagreement over the best way to prevent attackers from learning about the kernel's address-space layout.

    There are a number of ways for a kernel pointer value to find its way out to user space, but the most common path by far is the printk() function. There are on the order of 50,000 printk() calls in the kernel, any of which might include the value of a kernel pointer. Other places in the kernel use the underlying vsprintf() mechanism to format data for virtual files; they, too, often leak pointer values. A blanket ban on printing pointer values could solve this problem — if it could be properly enforced — but it would also prevent printing such values when they are really needed. Debugging kernel problems is one obvious use case for printing pointers, but there are others.

  • Continuous-integration testing for Intel graphics

    Two separate talks, at two different venues, give us a look into the kinds of testing that the Intel graphics team is doing. Daniel Vetter had a short presentation as part of the Testing and Fuzzing microconference at the Linux Plumbers Conference (LPC). His colleague, Martin Peres, gave a somewhat longer talk, complete with demos, at the X.Org Developers Conference (XDC). The picture they paint is a pleasing one: there is lots of testing going on there. But there are problems as well; that amount of testing runs afoul of bugs elsewhere in the kernel, which makes the job harder.

    Developing for upstream requires good testing, Peres said. If the development team is not doing that, features that land in the upstream kernel will be broken, which is not desirable. Using continuous-integration (CI) along with pre-merge testing allows the person making a change to make sure they did not break anything else in the process of landing their feature. That scales better as the number of developers grows and it allows developers to concentrate on feature development, rather than bug fixing when someone else finds the problem. It also promotes a better understanding of the code base; developers learn more "by breaking stuff", which lets them see the connections and dependencies between different parts of the code.

An update on GnuPG

Filed under
GNU
Security

The GNU Privacy Guard (GnuPG) is one of the fundamental tools that allows a distributed group to have trust in its communications. Werner Koch, lead developer of GnuPG, spoke about it at Kernel Recipes: what's in the new 2.2 version, when older versions will reach their end of life, and how development will proceed going forward. He also spoke at some length on the issue of best-practice key management and how GnuPG is evolving to assist.

It is less than three years since attention was focused on the perilous position of GnuPG; because of systematic failure of the community to fund its development, Koch was considering packing it all in. The Snowden revelations persuaded him to keep going a little longer, then in the wake of Heartbleed there was a resurgent interest in funding the things we all rely on. Heartbleed led to the founding of the Core Infrastructure Initiative (CII). A grant from CII joined commitments from several companies and other organizations and an upsurge in community funding has put GnuPG on a more secure footing going forward.

  • Ubuntu 17.10: We're coming GNOME! Plenty that's Artful in Aardvark, with a few Wayland wails

    Ubuntu has done a good job of integrating a few plugins that improve GNOME's user experience compared to stock GNOME – most notably a modified version of the Dash-to-Dock and the App Indicator extensions, which go a long way toward making GNOME a bit more like Unity. It's worth noting that Ubuntu's fork of Dash-to-Dock lacks some features of the original, but you can uninstall the Ubuntu version in favour of the original if you prefer. In fact you can really revert to a pretty stock GNOME desktop with just a few tweaks. Canonical said it wasn't going to heavily modify GNOME and indeed it hasn't.

Over the past year, Mozilla has been working on a series of major changes to the Firefox browser, mainly for performance and security. These changes are referred to as Project Quantum. Some improvements arrived already with no major differences for its users.

Last month the major changes landed in the developer channel. These changes mark a major deadline for how extensions work. This deadline gave third party developers a chance to look at their extensions and make changes to remain compatible. It was an important milestone date for the various Firefox add-ons. Firefox 57 marks an end to the legacy XUL based extensions. Starting with version 57, Firefox supports only a new type of extension, named WebExtension.

3 Tools to Help You Remember Linux Commands

Filed under
Software

The Linux desktop has come a very long way from its humble beginnings. Back in my early days of using Linux, knowledge of the command line was essential—even for the desktop. That’s no longer true. Many users might never touch the command line. For Linux system administrators, however, that’s not the case. In fact, for any Linux admin (be it server or desktop), the command line is a requirement. From managing networks, to security, to application and server settings—there’s nothing like the power of the good ol’ command line.

But, the thing is… there are a lot of commands to be found on a Linux system. Consider /usr/bin alone and you’ll find quite a lot of commands (you can issue ls /usr/bin/ | wc -l to find out exactly how many you have). Of course, these aren’t all user-facing executables, but it gives you a good idea of the scope of Linux commands. On my Elementary OS system, there are 2029 executables within /usr/bin. Even though I will use only a fraction of those commands, how am I supposed to remember even that amount?

How Eclipse is advancing IoT development

Development

Eclipse may not be the first open source organization that pops to mind when thinking about Internet of Things (IoT) projects. After all, the foundation has been around since 2001, long before IoT was a household word, supporting a community for commercially viable open source software development.

September's Eclipse IoT Day, held in conjunction with RedMonk's ThingMonk 2017 event, emphasized the big role Eclipse is taking in IoT development. It currently hosts 28 projects that touch a wide range of IoT needs and projects. While at the conference, I talked with Ian Skerritt, who heads marketing for Eclipse, about Eclipse's IoT projects and how Eclipse thinks about IoT more broadly.

Effective Strategies for Recruiting Open Source Developers

Filed under
OSS

Experienced open source developers are in short supply. To attract top talent, companies often have to do more than hire a recruiter or place an ad on a popular job site. However, if you are running an open source program at your organization, the program itself can be leveraged as a very effective recruiting tool. That is precisely where the new, free online guide Recruiting Open Source Developers comes in. It can help any organization in recruiting developers, or building internal talent, through nurturing an open source culture, contributing to open source communities, and showcasing the utility of new open source projects.

Why does your organization need a recruiting strategy? One reason is that the growing shortage of skilled developers is well documented. According to a recent Cloud Foundry report, there are a quarter-million job openings for software developers in the U.S. alone and half a million unfilled jobs that require tech skills. They’re also forecasting the number of unfillable developer jobs to reach one million within the next decade.

  • How to Choose a Linux Container Image

    A comparison of Linux container images talks about the best-practices in choosing an image. Architecture, security and performance are among the factors, while commercial users would also look for support options.

    A Linux container allows separate management of kernel space and user space components by utilizing cgroups and namespaces, which are resource and process isolation mechanisms. Solaris and BSD also have abstractions similar to Linux containers but the article's focus is on the latter only. The host running the container has the operating system kernel and a set of libraries and tools required to run containers. The container image, on the other hand, has the libraries, interpreters and application code required to run the application that is being distributed in the container. These depend on underlying system libraries. This is true for interpreted languages too as the interpreters themselves are written in low level languages.

  • The Four Pillars of Cloud-Native Operations

    As organizations shift their application strategies to embrace the cloud-native world, the purpose of the cloud transitions from saving money to delivering and managing applications. Platforms such as Cloud Foundry, Kubernetes, and Docker redefine the possibilities for application environments that utilize the cloud. It’s time for us as operations professionals to rethink how we approach our jobs in this new world. We should be asking, how do our organizations take advantage of cloud-native as a new mode of application delivery?

  • How to align your team around microservices

    Microservices have been a focus across the open source world for several years now. Although open source technologies such as Docker, Kubernetes, Prometheus, and Swarm make it easier than ever for organizations to adopt microservice architectures, getting your team on the same page about microservices remains a difficult challenge.

    For a profession that stresses the importance of naming things well, we've done ourselves a disservice with microservices. The problem is that that there is nothing inherently "micro" about microservices. Some can be small, but size is relative and there's no standard measurement unit across organizations. A "small" service at one company might be 1 million lines of code, but far fewer at another organization.

Canonical on Path to IPO as Ubuntu Unity Linux Desktop Gets Ditched

Filed under
Interviews
Ubuntu

In October 2010, Mark Shuttleworth, founder of the Ubuntu open-source operating system and CEO of Canonical, announced his grand plan to build a converged Linux desktop that would work on mobile devices, desktops and even TVs. He called the effort "Unity" and poured significant financial resources into it.

Seven years later, the Unity dream is dead.

On Oct. 19, Ubuntu 17.10 was released as the first Ubuntu Linux version since 2010 that didn't use Unity as the default Linux desktop. In a video interview with eWEEK, Shuttleworth details the rationale behind his decision to cancel Unity and why he has now put his company on the path toward an initial public offering (IPO).

Because Ubuntu has moved into the mainstream in a bunch of areas, including the cloud, he said some of the things his company had been doing were never going to be commercially sustainable.
