Those concerned about the proliferation of application-packaging formats will soon have one fewer to worry about. At his blog, Matthias Klumpp announces that he intends to scale back his work on Limba, the cross-distribution application-packaging format he has developed as an extension of the ideas in the earlier Listaller. The decision comes on the heels of discussions with Flatpak developer Alexander Larsson, since the two projects overlap in many respects: "Alex and I had very productive discussions, and except for the modularity issue, we were pretty much on the same page in every other aspect regarding the sandboxing and app-distribution matters."Given that he has several other active projects in development, Klumpp has decided to throttle back on Limba, although he will continue to hack on it "as a research project" and sees several opportunities where it might still fit into vendor-independent software distribution down the road. "This is good news for all the people out there using the Tanglu Linux distribution, AppStream-metadata-consuming services, PackageKit on Debian, etc. – those will receive more attention," Klumpp concludes.

For those who are wondering what Kubernetes is all about, Matt Butcher hasposted anillustrated guide for children. "Phippy loved life aboardCaptain Kube's ship and she enjoyed the company of her new friends (everyreplicated pod of Goldie was equally delightful). But as she thought backto her days on the scary hosted provider, she began to wonder if perhapsshe could also have a little privacy. 'It sounds like what you need,' saidCaptain Kube, 'is a namespace.'"

Qt 5.7 has been released, with a new Qt 3D module and other improvements."The future of user interfaces is moving towards heavier integrationof 3D graphics. 3D integration of Qt has always been possible with directOpenGL programming but with Qt 5.7 and the new Qt 3D module it is now easyto create 3D UIs and interact with 3D objects using high-level Qt C++ andQML APIs. Visualizing a 3D model with Qt 3D is now a matter of minutesinstead of hours or days of OpenGL programming. In addition to just 3Drendering, Qt 3D is a fully extensible 3D framework for near-realtimesimulations e.g. physics engine, artificial intelligence, collisiondetection. Qt 3D has been developed together with KDAB, a Qt ServicePartner and the biggest external contributor to Qt. For more informationabout KDAB, please visit www.kdab.com."

openSUSE has updated libxml2 (Leap42.1; 13.2: multiple vulnerabilities).SUSE has updated kernel (SLE12:privilege escalation).

The LWN.net Weekly Edition for June 16, 2016 is available.

Arch maintainer Kyle Keen speaks out against directdelivery of software by upstream projects. "Maintainers' greatestpower is the ability to outright say 'This is not good enough for ourusers' and consequently punish an ISV by either patching out the offensivepart or in extreme cases removing the software from the repositories. ISVsknow this and so don't act out. After 20 years of enforced good behaviorthis has lead to the idea of ISVs as 'the benevolent upstream developer.'This is why Linux doesn't have spyware, doesn't come with browser toolbars,doesn't bundle limited trials, doesn't nag you to purchase and doesn'tpummel you with advertising."

Debian has updated libav (code execution) and php5 (multiple vulnerabilities).openSUSE has updated clamav-database (Leap42.1: database refresh),monit (Leap42.1: disable SSLv3), and ntp (13.2: multiple vulnerabilities).SUSE has updated ntp (SLE11-SP4:multiple vulnerabilities) and php53(SOSC5, SMP2.1, SM2.1, SLE11-SP4: multiple vulnerabilities).

It has long been understood that static-analysis tools can be useful infinding (and defending against) bugs and security problems in code. One ofthe best places to implement such tools is in the compiler itself, since much of the work required toanalyze a program is already done in the compilation process. Despite thefact that GCC has had the ability to support security-oriented plugins forsome years, the mainline kernel has never adopted any such plugins. Thatsituation looks likely to change with the 4.8 kernel release, though.

Ars Technica reportsthat Ubuntu's snapd tool has beenported to other Linux distributions."To install snap packages on non-Ubuntu distributions, Linux desktopand server users will have to first install the newly cross-platformsnapd. This daemon verifies the integrity of snap packages, confines theminto their own restricted space, and acts as a launcher. Instructions forcreating snaps and installing snapd on a variety of distributions areavailable at this website.Snapd itself is installed as traditional packages on these other operatingsystems. That means there's a snapd RPM package for Fedora, forexample. It's the same snapd code for every Linux distribution, justpackaged differently, and applications packaged as snaps should work on anyLinux distro running snapd without needing to be re-packaged."Snapd is available for Arch, Debian, and Fedora. It's also being tested byCentOS, Elementary, Gentoo, Mint, openSUSE, OpenWrt and RHEL.

Debian has updated icedove (code execution).Debian-LTS has updated libav (code execution).openSUSE has updated libtasn1(13.2: two denial of service vulnerabilities) and nodejs (Leap42.1, 13.2: multiple vulnerabilities).Oracle has updated kernel 4.1.12 (OL7; OL6:privilege escalation), kernel 3.8.13 (OL7; OL6:privilege escalation), kernel 2.6.39 (OL6; OL5:privilege escalation).Red Hat has updated kernel(RHEL6.5: two remote denial of service vulnerabilities).SUSE has updated ImageMagick(SLE12-SP1: command execution) and ntp (SLE12-SP1; SLE12: multiple vulnerabilities).

Version 2.9.0 of the Git source-code management system is out. There arevarious improvements and small changes that maintainers of scripts usingGit will want to look at, but no major changes.

Allison Lortie writesabout a new proposed GTK release scheme that may take some getting usedto."Meanwhile, Gtk 4.0 will not be the final stable API of what we wouldcall 'Gtk 4'. Each 6 months, the new release (Gtk 4.2, Gtk 4.4, Gtk 4.6)will break API and ABI vs. the release that came before it. Theseincompatible minor versions will not be fully parallel installable; theywill use the same pkg-config name and the same header file directory. Wewill, of course, bump the soname with each new incompatible release — youwill be able to run Gtk 4.0 apps alongside Gtk 4.2 and 4.4 apps, but youwon’t be able to build them on the same system. This policy fits the modelof how most distributions think about libraries and their 'developmentpackages'." Only the last release in each major number series(expected every two years) would have a stable API. Read the whole thingto fully understand what is being proposed.

Let's Encrypt has a preliminaryreport about an email address disclosure. "On June 11 2016(UTC), we started sending an email to all active subscribers who providedan email address, informing them of an update to our subscriberagreement. This was done via an automated system which contained a bug thatmistakenly prepended between 0 and 7,618 other email addresses to the bodyof the email. The result was that recipients could see the email addressesof other recipients. The problem was noticed and the system was stoppedafter 7,618 out of approximately 383,000 emails (1.9%) were sent. Eachemail mistakenly contained the email addresses from the emails sent priorto it, so earlier emails contained fewer addresses than later ones."A postmortem is underway. (Thanks to Paul Wise)Update: postmortem results have been added to the incident report. "A small piece of software had been written to handle one-off mass emailing to our subscribers. It was being used for the first time when this incident occurred.The software went through code review and testing as it was beingdeveloped, but testing was insufficient. It did not catch a bug whichprepended the email addresses of prior recipients to the body of emails. Insufficient testing is considered to be the root cause of this incident."

Thomas Gleixner wrote the following to us: The Linux Kernel community ismourning the passing of Hans-Jürgen Koch. Hans was a free-software enthusiast and an active contributor. He worked on RadioData System support both in kernel and user space and was the main author andmaintainer of the UIO subsystem and contributed in various ways to the Linuxkernel as a professional and hobbyist. He authored a UIO book, gavecountless talks at various open-source conferences, and served as a member of theLinuxtag program committee.His calm and modest nature made it a pleasure to work with him. Meeting him inperson was always a enjoyable experience. His interests spanned a broad rangefrom literature, music and history to politics and engagement for the germanbranch of Friends of the Earth. His wicked sense of humor along with hisalways ready to be told bag of anecdotes enlivened quite some social events.He will be sorely missed and our thoughts are with his family and friends.

The third 4.7 prepatch is out for testing.Linus says: "The diffstat looks fairly normal and innocuous. There'smore of a filesystem component to it than usual, but that's mostly someadded new btrfs tests, and if you ignore that part it's all the normalstuff: drivers dominate (gpu and networking drivers are the bulk, butthere's i2c, rdma, ...) with some arch updates, and general networkingcode. And the usual random stuff all over."

On his blog, Andy Grover makes a case for using the Rust language for new projects instead of C or Python. "Second, there are people like me, people working in C and Python on Linux systems-level stuff — the “plumbing”, who are frustrated with low productivity. C and Python have diametrically-opposed advantages and disadvantages. C is fast to run but slow to write, and hard to write securely. Python is more productive but too slow and RAM-hungry for something running all the time, on every system. We must deal with getting C components to talk to Python components all the time, and it isn’t fun. Rust is the first language that gives a system programmer performance and productivity. These people might see Rust as a chance to increase security, to increase their own productivity, to never have to touch libtool/autoconf ever again, and to solve the C/Python dilemma with a one language solution."

On The Mozilla blog, Chris Riley announces the "Secure Open Source" (SOS) fund to provide money to help with the security of open-source software."The SOS Fund will provide security auditing, remediation, and verification for key open source software projects. The Fund is part of the Mozilla Open Source Support program (MOSS) and has been allocated $500,000 in initial funding, which will cover audits of some widely-used open source libraries and programs. But we hope this is only the beginning. We want to see the numerous companies and governments that use open source join us and provide additional financial support. We challenge these beneficiaries of open source to pay it forward and help secure the Internet.Security is a process. To have substantial and lasting benefit, we need to invest in education, best practices, and a host of other areas. Yet we hope that this fund will provide needed short-term benefits and industry momentum to help strengthen open source projects." SOS sounds similar in scope to the Core Infrastructure Initiative (CII) set up by the Linux Foundation.

The first version of KDE neon, which is a distribution based on Ubuntu 16.04 that is meant to be a stable platform on which to try the latest Plasma desktop, has been released."KDE neon User Edition 5.6 is based on the latest version of Plasma 5.6 and intends to showcase the latest KDE technology on a stable foundation. It is a continuously updated installable image that can be used not just for exploration and testing but as the main operating system for people enthusiastic about the latest desktop software. It comes with a slim selection of apps, assuming the user's capacity to install her own applications after installation, to avoid cruft and meaningless weight to the ISO. The KDE neon team will now start adding all of KDE's applications to the neon archive.Since the announcement of the project four months ago the team has been working on rolling out our infrastructure, using current best-practice devops technologies. A continuous integration Jenkins system scans the download servers for new releases and automatically fires up computers with Docker instances to build packages. We work in the open and as a KDE project any KDE developer has access to our packaging Git repository and can make fixes, improvements and inspect our work."

Nikolai Tschacher demonstrateshow easy it is to run arbitrary code by way of "typosquatting" uploadsto programming language download sites. "Because everybody canupload any package on PyPi, it is possible to create packages which aretypo versions of popular packages that are prone to be mistyped. And ifsomebody unintentionally installs such a package, the next question comesintuitively: Is it possible to run arbitrary code and take over thecomputer during the installation process of a package?" He tried anexperiment and was able to run a little program that phoned home fromthousands of systems.

The Qt Blog announcesthe launch of the Qt Automotive Suite. "With cumulativeexperience from over 20 automotive projects it was noted how Qt is reallywell suited to the needs of building IVIs and Instrument Clusters, thatthere were already millions of vehicles on the road with Qt inside, andthat there were a lot of ongoing projects. There was though a feeling thatthings could be even better, that there were still a few things holdingback the industry, contributing to the sense that shipped IVI systems couldbe built faster, cheaper and with a higher quality."

Linux users tend to pride themselves on their position at the leading edgeof a fast-moving development community. But, in truth, much of what we dois rooted in many decades of Unix tradition, and we tend to get grumpy whenyoung developers show up and start changing things around. A recent change ofdefault in systemd represents such a change and the kind of response thatit brings out; as a result, Linux distributors are going to have to make adecision on whether they should preserve the way things have always workedor make a change that, while potentially disruptive to users, is arguably astep toward more predictable, controllable, and secure behavior.

Firefox 47 has been released. This version enables the VP9 video codec forusers with fast machines, plays embedded YouTube videos with HTML5 video ifFlash is not installed, and more. There is a blogpost about these and other improvements. "Now, we are making iteven easier to access synced tabs directly in your desktop Firefoxbrowser.

The second 4.7 prepatch is now availablefor testing. Linus says: "There's a late non-fix I took even thoughthe merge window is over, because I've been wanting it for a while. I doubtanybody notices the actual effects of a pty change/cleanup that means thatour old disgusting DEVPTS_MULTIPLE_INSTANCES kernel config option is gone,because the cleanup means that it is no longer needed." For detailson this change, see this article from lastweek's Kernel Page.

At his blog, Gunnar Wolf urges developers to stop using"short" (eight hex-digit) PGP key IDs as soon as possible. Theimpetus for the advice originates with Debian's Enrico Zini, who recentlyfound two keys sharing the same short ID in the wild. Thepossibility of short-ID collisions has been known for a while, but itis still disconcerting to see in the wild. "Those three keysare not (yet?) uploaded to the keyservers, though... But we can expectthem to appear at any point in the future. We don't know who is behindthis, or what his purpose is. We just know this looks veryevil."Wolf goes on to note that short IDs are not merely human-readableconveniences, but are actually used to identify PGP keys in somesoftware programs. To mitigate the risk, he recommends configuringGnuPG to never shows short IDs, to ensure that other programs do notconsume short IDs, and to "only sign somebody else's key if yousee and verify its full fingerprint. [...] And there are surely many other important recommendations. But this is a good set of points to start with."

At OSCON2016 in Austin, a panel of invited experts debated thealways-thorny subject of how open-source software projects deal withpatents. The panel was packed, featuring representatives from thefree-software world, commerce, and the legal community, so there wasscarcely enough time to move through the prepared topics in the timeallotted, much less to take questions from the audience. But thediscussion was able to highlight a number of current issues, includingpatent abolition, implicit patent licenses, and where theopen-source community should focus its efforts to improve matters.

PostgreSQL's annual developer conference, PGCon, took place in May, which made it agood place to get a look at the new PostgreSQL features coming in version9.6. The first 9.6beta was released just the week before and severalcontributors demonstrated key changes at the conference in Ottawa. Formany users, this was the first time to see the finished versions offeatures that had been under development for months or years.

For those who have been wondering about the exodus from ownCloud, the announcement of a company called"Nextcloud" should make things clear. "Started by the well knownopen source file sync and share developer Frank Karlitschek and joined bythe most active contributors to his previous project, building on itsmature code base, we offer a more reliable and sustainable solution forusers and customers. We will develop a drop-in replacement for that legacycode base over the coming weeks, providing the bug fixes and securityhardening all users need and the Enterprise Subscription capabilitiesenterprise customers require."See also thisblog post from Jos Poortvliet.

There is no doubt that the addition of containertechnologies to Linux has created a lot of value,allowing workloads to be effectively and efficiently isolated from each other.Implementing these technologies presents a number of challenges,particularly as much of Linux and Unix was designed to use singletons:objects of which there could never ever be more than one, such ashost names, network routing tables, or process-ID namespaces.Containers require this design approach to be revised as they needmultiple instances of these objects. A singleton that has been causing problems recently is the set of pseudoterminals (TTYs).<p>Click below (subscribers only) for the full article from Neil Brown.

Thiswhite paper by Jesse Hertz [PDF] examines various ways to compromise andescape from containers on Linux systems. "A common configuration forcompanies offering PaaS solutions built on containers is to have multiplecustomers’ containers running on the same physical host. By default, bothLXC and Docker setup container networking so that all containers share thesame Linux virtual bridge. These containers will be able to communicatewith each other. Even if this direct network access is disabled (using the–icc=false flag for Docker, or using iptables rules for LXC), containersaren’t restricted for link-layer traffic. In particular, it is possible(and in fact quite easy) to conduct an ARP spoofing attack on anothercontainer within the same host system, allowing full middle-person attacksof the targeted container’s traffic."

Greg KH has released stable kernels 4.6.1,4.5.6, 4.4.12, and 3.14.71. All of them contain important fixes.

The Open Source Initiative (OSI) has announced the Open Source License API,to "allow third parties to becomelicense-aware, and give organizations the ability to clearly determine if alicense is, in fact, an Open Source license, from the authoritative sourceregarding Open Source licenses, the OSI."

CoreOS has announceda new project called Torus which is creating a distributed storage systemfor containers. "At its core, Torus is a library with an interfacethat appears as a traditional file, allowing for storage manipulationthrough well-understood basic file operations. Coordinated and checkpointedthrough etcd’s consensus process, this distributed file can be exposed touser applications in multiple ways. Today, Torus supports exposing thisfile as block-oriented storage via a Network Block Device (NBD). We alsoexpect that in the future other storage systems, such as object storage,will be built on top of Torus as collections of these distributed files,coordinated by etcd." The project is quite young, and the currentrelease is a "prototype version."

The Tor Browser Team has announcedthe release of Tor browser 6.0. This release brings the browserup-to-date with Firefox 45-ESR, which provides better support for HTML5video on Youtube, as well as a host of other improvements. DuckDuckGo isnow the default search engine. "Lately, we got a couple of comments on our blog and via email wondering why we are now using DuckDuckGo as the default search engine and not Disconnect anymore. Well, we still use Disconnect. But for a while now Disconnect has no access to Google search results anymore which we used in Tor Browser. Disconnect being more a meta search engine which allows users to choose between different search providers fell back to delivering Bing search results which were basically unacceptable quality-wise. While Disconnect is still trying to fix the situation we asked them to change the fallback to DuckDuckGo as their search results are strictly better than the ones Bing delivers."

Qubes founder Joanna Rutkowska writes about how Qubesworks to avoid building compromised software into its distribution."Ultimately, we would like to introduce a multiple-signature scheme,in which several developers (from different countries, social circles,etc.) can sign Qubes-produced binaries and ISOs. Then, an adversary wouldhave to compromise all the build locations in order to get backdooredversions signed. For this to happen, we need to make the build processdeterministic (i.e. reproducible). Yet, this task still seems to be yearsahead of us."
