Moving Compiler Dependency Checks to Kconfig

Linux Journal - mer, 09/19/2018 - 07:00
by Zack Brown

The Linux kernel config system, Kconfig, uses a macro language very similar to the make build tool's macro language. There are a few differences, however. And of course, make is designed as a general-purpose build tool while Kconfig is Linux-kernel-specific. But, why would the kernel developers create a whole new macro language so closely resembling that of an existing general-purpose tool?

One reason became clear recently when Linus Torvalds asked developers to add an entirely new system of dependency checks to the Kconfig language, specifically testing the capabilities of the GCC compiler.

It's actually an important issue. The Linux kernel wants to support as many versions of GCC as possible—so long as doing so would not require too much insanity in the kernel code itself—but different versions of GCC support different features. The GCC developers always are tweaking and adjusting, and GCC releases also sometimes have bugs that need to be worked around. Some Linux kernel features can only be built using one version of the compiler or another. And, some features build better or faster if they can take advantage of various GCC features that exist only in certain versions.

Up until this year, the kernel build system has had to check all those compiler features by hand, using many hacky methods. The art of probing a tool to find out if it supports a given feature dates back decades and is filled with insanity. Imagine giving a command that you know will fail, but giving it anyway because the specific manner of failure will tell you what you need to know for a future command to work. Now imagine hundreds of hacks like that in the Linux kernel build system.

Part of the problem with having those hacky checks in the build system is that you find out about them only during the build—not during configuration. But since some kernel features require certain GCC versions, the proper place to learn about the GCC version is at config time. If the user's compiler doesn't support a given feature, there's no reason to show that feature in the config system. It should just silently not exist.

Linus requested that developers migrate those checks into the Kconfig system and regularize them into the macro language itself. This way, kernel features with particular GCC dependencies could identify those dependencies and then show up or not show up at config time, according to whether those dependencies had been met.

That's the reason simply using make wouldn't work. The config language had to represent the results of all those ugly hacks in a friendly way that developers could make use of.

Writing More Compact Bash Code

Linux Journal - mar, 09/18/2018 - 07:00
by Mitch Frazier

In any programming language, idioms may be used that may not seem obvious from reading the manual. Often these usages of the language represent ways to make your code more compact (as in requiring fewer lines of code). Of course, some will eschew these idioms believing they represent bad style. Style, of course, is in the eyes of beholder, and this article is not intended as an exercise in defining good or bad style. So for those who may be tempted to comment on the grounds of style I would (re)direct your attention to /dev/null.

Globbing and Regex: So Similar, So Different

Linux Journal - lun, 09/17/2018 - 08:51
by Shawn Powers

Grepping is awesome, as long as you don't glob it up! This article covers some grep and regex basics.

There are generally two types of coffee drinkers. The first type buys a can of pre-ground beans and uses the included scoop to make their automatic drip coffee in the morning. The second type picks single-origin beans from various parts of the world, accepts only beans that have been roasted within the past week and grinds those beans with a conical burr grinder moments before brewing in any number of complicated methods. Text searching is a bit like that.

For most things on the command line, people think of *.* or *.txt and are happy to use file globbing to select the files they want. When it comes to grepping a log file, however, you need to get a little fancier. The confusing part is when the syntax of globbing and regex overlap. Thankfully, it's not hard to figure out when to use which construct.

Globbing

The command shell uses globbing for filename completion. If you type something like ls *.txt, you'll get a list of all the files that end in .txt in the current directory. If you do ls R*.txt, you'll get all the files that start with capital R and have the .txt extension. The asterisk is a wild card that lets you quickly filter which files you mean.

You also can use a question mark in globbing if you want to specify a single character. So, typing ls read??.txt will list readme.txt, but not read.txt. That's different from ls read*.txt, which will match both readme.txt and read.txt, because the asterisk means "zero or more characters" in the file glob.

Here's the easy way to remember if you're using globbing (which is very simple) vs. regular expressions: globbing is done to filenames by the shell, and regex is used for searching text. The only frustrating exception to this is that sometimes the shell is too smart and conveniently does globbing when you don't want it to—for example:

grep file* README.TXT

In most cases, this will search the file README.TXT looking for the regular expression file*, which is what you normally want. But if there happens to be a file in the current folder that matches the file* glob (let's say filename.txt), the shell will assume you meant to pass that to grep, and so grep actually will see:

grep filename.txt README.TXT

Gee, thank you so much Mr. Shell, but that's not what I wanted to do. For that reason, I recommend always using quotation marks when using grep. 99% of the time you won't get an accidental glob match, but that 1% can be infuriating. So when using grep, this is much safer:

grep "file*" README.TXT

Because even if there is a filename.txt, the shell won't substitute it automatically.

News briefs for September 17, 2018.

Linus Torvalds is taking a break. In his rc4 email update over the weekend, he writes about his scheduling mix-up with the kernel summit and having a "look yourself in the mirror moment", and then (to summarize), he writes: "hey, I need to change some of my behavior, and I want to apologize to the people that my personal behavior hurt and possibly drove away from kernel development entirely. I am going to take time off and get some assistance on how to understand people's emotions and respond appropriately."

Krita announced its developer fundraiser "let's squash the bugs"! The goal this year for the open-source graphics editor is to "fix bugs, make Krita more stable and bring more polish and shine to all the features we have made possible together". Visit here to learn how you can help.

A vulnerability, has been discovered in Alpine Linux, which is commonly used in Docker images. Worst-case scenario, according to The Register, an "attacker could intercept apk's package requests during Docker image building, inject them with malicious code, and pass them along to the target machines that would unpack and run the code within their Docker container." Update apk and images now.

Alexander Larsson, lead developer and creator of the Flatpak package system, announced via Twitter that it now works on Windows Subsystem for Linux. See the post on Neowin for more on the story, and the "hacky workarounds" required.

Lights, Camera, Open Source: Hollywood Turns to Linux for New Code Sharing Initiative

Linux Journal - ven, 09/14/2018 - 08:08
by Gabriel Avner

Software has permeated all industries, bringing us technologies to help create fantastic products and even works of art.No longer confined to sectors whose products are software-focused, everyone from the automotive to the medical industries are writing their own code to meet their needs, some of which may surprise you.

In looking to code smarter, faster and more efficiently, developers across the globe and industries are turning to open-source components that allow them to add powerful features to their work without having to write everything from scratch themselves. One of the latest groups to embrace the Open Source movement is the entertainment industry.

Similar to many other initiatives that have come together in recent years to support the sharing of code between companies, a number of key players under the umbrella of the Academy of Motion Picture Arts and Sciences (AMPAS) have teamed up with The Linux Foundation to establish the Academy Software Foundation (ASWF). Members include companies like Disney, Google, Dreamworks, Epic Games and Intel, just to name a few.

Facing the Reality of Open Source

The drive for these entertainment industry players to team up with The Linux Foundation comes after a two-year study by the AMPAS’ Science and Technology Council into how the sector was using open source. Their survey found that some 84% were using open source in their work, specifically in the fields of animation and visual effects.

However, even as these actors understood the benefits of using open-source projects that were being developed by others, maintaining an ecosystem of sharing software between often competing interests proved to be a challenge. Issues of governance, licensing, multiple versions of libraries and siloed development by individual companies proved to be significant pain points.

According to information available from the ASWF, they are providing much of the infrastructure for the projects, including running their CI server on Jenkins where code can go through the build, test and eventually release for use by the members. Using a centralized system, developers at the various member companies can upload their code to the ASWF repository and CI where it is then available to the other teams.

They note that along with support for Linux, their CI infrastructure will offer service for Windows and Mac desktops and servers, an important requirement in an industry with a high level of Apple usage.

A Look at KDE's KAlgebra

Linux Journal - jeu, 09/13/2018 - 07:00
by Joey Bernard

Many of the programs I've covered in the past have have been desktop-environment-agnostic—all they required was some sort of graphical display running. This article looks at one of the programs available in the KDE desktop environment, KAlgebra.

You can use your distribution's package management system to install it, or you can use Discover, KDE's package manager. After it's installed, you can start it from the command line or the launch menu.

When you first start KAlgebra, you get a blank slate to start doing calculations.

Figure 1. When you start KAlgebra, you get a blank canvas for doing calculations.

The screen layout is a large main pane where all of the calculations and their results are displayed. At the top of this pane are four tabs: Calculator, 2D Graph, 3D Graph and Dictionary. There's also a smaller pane on the right-hand side used for different purposes for each tab.

In the calculator tab, the side pane gives a list of variables, including predefined variables for things like pi or euler, available when you start your new session. You can add new variables with the following syntax:

a := 3

This creates a new variable named a with an initial value of 3. This new variable also will be visible in the list on the right-hand side. Using these variables is as easy as executing them. For example, you can double it with the following:

a * 2

There is a special variable called ans that you can use to get the result from your most recent calculation. All of the standard mathematical operators are available for doing calculations.

Figure 2. KAlgebra lets you create your own variables and functions for even more complex calculations.

There's also a complete set of functions for doing more complex calculations, such as trigonometric functions, mathematical functions like absolute value or floor, and even calculus functions like finding the derivative. For instance, the following lets you find the sine of 45 degrees:

sin(45)

You also can define your own functions using the lambda operator ->. If you want to create a function that calculates cubes, you could do this:

x -> x^3

This is pretty hard to use, so you may want to assign it to a variable name:

cube := x -> x^3

You then can use it just like any other function, and it also shows up in the list of variables on the right-hand side pane.

Support for a LoRaWAN Subsystem

Linux Journal - mer, 09/12/2018 - 08:08
by Zack Brown

Sometimes kernel developers find themselves competing with each other to get their version of a particular feature into the kernel. But sometimes developers discover they've been working along very similar lines, and the only reason they hadn't been working together was that they just didn't know each other existed.

Recently, Jian-Hong Pan asked if there was any interest in a LoRaWAN subsystem he'd been working on. LoRaWAN is a commercial networking protocol implementing a low-power wide-area network (LPWAN) allowing relatively slow communications between things, generally phone sensors and other internet of things devices. Jian-Hong posted a link to the work he'd done so far: https://github.com/starnight/LoRa/tree/lorawan-ndo/LoRaWAN.

He specifically wanted to know "should we add the definitions into corresponding kernel header files now, if LoRaWAN will be accepted as a subsystem in Linux?" The reason he was asking was that each definition had its own number. Adding them into the kernel would mean the numbers associated with any future LoRaWAN subsystem would stay the same during development.

However, Marcel Holtmann explained the process:

When you submit your LoRaWAN subsystem to netdev for review, include a patch that adds these new address family definitions. Just pick the next one available. There will be no pre-allocation of numbers until your work has been accepted upstream. Meaning, that the number might change if other address families get merged before yours. So you have to keep updating. glibc will eventually follow the number assigned by the kernel.

Meanwhile, Andreas Färber said he'd been working on supporting the same protocol himself and gave a link to his own proof-of-concept repository: https://github.com/afaerber/lora-modules.

On learning about Andreas' work, Jian-Hong's response was, "Wow! Great! I get new friends :)"

That's where the public conversation ended. The two of them undoubtedly have pooled their energies and will produce a new patch, better than either of them might have done separately.

Stop Killing Your Cattle: Server Infrastructure Advice

Linux Journal - mar, 09/11/2018 - 07:00
by Kyle Rankin

It's great to treat your infrastructure like cattle—until it comes to troubleshooting.

If you've spent enough time at DevOps conferences, you've heard the phrase "pets versus cattle" used to describe server infrastructure. The idea behind this concept is that traditional infrastructure was built by hand without much automation, and therefore, servers were treated more like special pets—you would do anything you could to keep your pet alive, and you knew it by name because you hand-crafted its configuration. As a result, it would take a lot of effort to create a duplicate server if it ever went down. By contrast, modern DevOps concepts encourage creating "cattle", which means that instead of unique, hand-crafted servers, you use automation tools to build your servers so that no individual server is special—they are all just farm animals—and therefore, if a particular server dies, it's no problem, because you can respawn an exact copy with your automation tools in no time.

If you want your infrastructure and your team to scale, there's a lot of wisdom in treating servers more like cattle than pets. Unfortunately, there's also a downside to this approach. Some administrators, particularly those that are more junior-level, have extended the concept of disposable servers to the point that it has affected their troubleshooting process. Since servers are disposable, and sysadmins can spawn a replacement so easily, at the first hint of trouble with a particular server or service, these administrators destroy and replace it in hopes that the replacement won't show the problem. Essentially, this is the "reboot the Windows machine" approach IT teams used in the 1990s (and Linux admins sneered at) only applied to the cloud.

This approach isn't dangerous because it is ineffective. It's dangerous exactly because it often works. If you have a problem with a machine and reboot it, or if you have a problem with a cloud server and you destroy and respawn it, often the problem does go away. Because the approach appears to work and because it's a lot easier than actually performing troubleshooting steps, that success then reinforces rebooting and respawning as the first resort, not the last resort that it should be.

GNU Nano Announces Version 3.0, ZFS on Linux Version 0.7.10 Released, Qt 3D Studio 2.1 Beta 1 Now Available, Tor Project's New Android App in the Works and Elive 3.0 Is Out

Linux Journal - lun, 09/10/2018 - 08:46

News briefs September 10, 2018.

GNU Nano 3.0 "water flowing underground" was released yesterday. This release of the popular text editor speeds up file reading by 70%, doubles the speed of reading ascii text, changes the way words at line boundaries are deleted and much more.

ZFS on Linux has released version 0.7.10. According to the Phoronix post, the most notable change is the Linux 4.18 kernel is now supported, and the new version "also has build improvements, support for Debian DKMS builds, a default 4 KiB ashift is added to Amazon EC2 NVMe devices, and various other minor enhancements and several bug fixes". See the zfs-0.7.10 GitHub page for more details.

The Qt 3D Studio 2.1 Beta 1 release was announced this morning. The release features a new Boolean data type, a new project structure and improvements that make working with sub-projects more convenient. You can download the Qt online installer from here.

The Tor Project is working on an Android app for anonymous browsing, TNW reports. The official launch is scheduled for next year, but the alpha is available for testing from Google Play.

Elive 3.0 is out after eight years of development. The release announcement notes that "the result is simply amazing and the integration is gorgeous, it is not even possible to describe every inside feature and the new website only contains a small portion of its characteristics."

What Is the Point of Mozilla?

Linux Journal - lun, 09/10/2018 - 08:07
by Glyn Moody

Is Mozilla a software organization or an advocacy group?

Few journeys in the world of open source have been as exciting as Mozilla's. Its birth was dramatic. Netscape, the pioneering company whose Netscape Navigator browser shaped the early Web, had enjoyed the most successful IPO up until then, valuing the 18-month-year-old company at nearly $3 billion. That was in 1995. Three years later, the company was in freefall, as the browser wars took their toll, and Microsoft continued to gain market share with its Internet Explorer, launched alongside Windows 95. Netscape's response was bold and unprecedented. On January 27, 1998, it announced that it was making the source code for the next generation of its web browser freely available under a GPL-like license.

Although of huge symbolic importance for the still-young Free Software world—the term "open source" was coined only a month after Netscape's announcement—the release and transformation of the code for what became the Mozilla browser suite was fraught with difficulties. The main problem was trying to re-write the often problematic legacy code of Netscape Navigator. Mozilla 1.0 was finally released in 2002, but by then, Internet Explorer dominated the sector. The failure of the Mozilla browser to make much of an impact ultimately spurred development of the completely new Firefox browser. Version 1.0 was launched in 2004, after three years of work.

Microsoft's failure to update its flabby Internet Explorer 6 browser for more than five years meant that successive releases of Firefox were steadily gaining market share—and fans. As I wrote in Linux Journal in June 2008:

Three things are striking about the recent launch of Firefox 3. First, the unanimity about the quality of the code: practically everyone thinks it's better in practically every respect. Secondly, the way in which the mainstream media covered its launch: it was treated as a normal, important tech story—gone are the days of supercilious anecdotes about those wacky, sandal-wearing free software anoraks. And finally—and perhaps most importantly—the scale and intensity of participation by the millions of people who have downloaded the software in the last week.

Tor Browser 8.0 Released, EU Votes Next Week on Copyright Directive, Indico Launches Open-Source Project Finetune, Linux Mint 19.1 Release to Come Late Fall, KDE's Akademy 2018 Videos Now Available

Linux Journal - ven, 09/07/2018 - 09:24

News briefs for September 7, 2018.

Tor Browser version 8.0 was released this week. This is the first stable release based on Firefox 60 ESR, and it includes "a new user onboarding experience; an updated landing page that follows our styleguide; additional language support; and new behaviors for bridge fetching, displaying a circuit, and visiting .onion sites." You can download it from here.

On September 12, the EU votes on the Directive on Copyright in the Digital Single Market. Of particular concern are Article 13 upload filters, "which would scan all content uploaded to online platforms for any copyrighted works and prevent those works from going online if a match is discovered", and Article 11, which would require "anyone using snippets of journalistic content to first get a license or pay a fee to the publisher for its use online". See The Creative Commons for information on the issues. If you're in the EU, make your voice heard.

Indico, "provider of Enterprise AI solutions for intelligent process automation", announced a new open-source project named Finetune this week that enhances "the performance of machine learning for natural language processing". According to the press release, this project "offers users a single, general-purpose language model which can be easily tuned to solve a variety of different tasks involved in text and document-based workflows". See also the Indico blog for more background information.

Linux Mint announces that the 19.1 release, code-named Tessa, is scheduled for November or December 2018. The upcoming version will be supported until 2023.

KDE's Akademy 2018 videos are now all online. You can download them from the repository or view the YouTube Playlist.
