Check Point has discovered four local-root vulnerabilities inQualcomm-based Android devices and is hyping the result as "QuadRooter"."QuadRooter is a set of four vulnerabilities affecting Androiddevices built using Qualcomm chipsets. Qualcomm is the world’s leadingdesigner of LTE chipsets with a 65% share of the LTE modem basebandmarket. If any one of the four vulnerabilities is exploited, an attackercan trigger privilege escalations for the purpose of gaining root access toa device." Actually getting the report requires registration. Allfour vulnerabilities are in Android-specific code; three of them are inout-of-tree modules (kgsl and ipc_router); the fourth is in the "ashmem" code in the staging tree.

Linus has released the 4.8-rc1 prepatch andclosed the merge window for this development cycle — sort of. "Iactually still have a few pull requests pending in my inbox that I justwanted to take another look at before merging, but the large bulk of themerge window material has been merged, and I wanted to make sure therearen't any new ones coming in." A total of 11,618 non-mergechangesets were pulled during the merge window.

The Let's Encrypt project, which provides a free SSL/TLS certificate authority (CA), has announced that Mozilla has accepted the project's root key into the Mozilla root program and will be trusted by default as of Firefox 50. This is a step forward from Let's Encrypt's earlier status. "In order to start issuing widely trusted certificates as soon as possible, we partnered with another CA, IdenTrust, which has a number of existing trusted roots. As part of that partnership, an IdenTrust root 'vouches for' the certificates that we issue, thus making our certificates trusted. We’re incredibly grateful to IdenTrust for helping us to start carrying out our mission as soon as possible. However, our plan has always been to operate as an independently trusted CA. Having our root trusted directly by the Mozilla root program represents significant progress towards that independence." The project has also applied for inclusion the CA trust roots maintained by Apple, Microsoft, Google, Oracle, and Blackberry. News on those programs is still pending.

The 2.24 version of the GNU C Library (glibc) has been released. It comeswith lots of bug fixes, including five for security vulnerabilities (fourstack overflows and a memory leak). Some deprecated features havebeen removed, as well as deprecating the readdir_r() andreaddir64_r() functions in favor of readdir() andreaddir64(). There are also additions to the math library(nextup*() and nextdown*()) to return the nextrepresentable value toward either positive or negative infinity.

The Tor Blog looks at using Pluggable Transports to avoid country-level Tor blocking. There are some new easy-to-follow graphical directions for using the transports."Many repressive governments and authorities benefit from blocking their users from having free and open access to the internet. They can simply get the list of Tor relays and block them. This bars millions of people from access to free information, often including those who need it most. We at Tor care about freedom of access to information and strongly oppose censorship. This is why we've developed methods to connect to the network and bypass censorship. These methods are called Pluggable Transports (PTs).Pluggable Transports are a type of bridge to the Tor network. They take advantage of various transports and make encrypted traffic to Tor look like not-interesting or garbage traffic. Unlike normal relays, bridge information is kept secret and distributed between users via BridgeDB."

The LWN.net Weekly Edition for August 4, 2016 is available.

It has been some time since our last update on the state of LWN itself.That's somewhat by design, as we'd rather be writing about the communityand the code than ourselves. Occasionally, though, we do like to updateour readers and subscribers on the state of the operation, especially whenthere is some news to report, as is the case now.

Inaddition, multiple signature descriptions are now supported, along withimport and export of signatures from OOXML files.Interoperability features have also been improved, with better Writerimport filters for DOCX and RTF files, and the added support for Wordfor DOS legacy documents."There's a lot more; see therelease notes [PDF] for an illustrated list.See also: thispost from Michael Meeks on the last year of LibreOffice development.

The 4.7 kernel was released onJuly 24, so longtime readers might be wondering where the usualdevelopment statistics are. We're running a little late this time around,but for good reason — Greg Kroah-Hartman obtained information from a largenumber of developers on who they work for, and we're now able to use thatinformation to produce better numbers. Of course, the overall story hasn'tchanged a whole lot — kernel development is relatively boring andpredictable these days — but each cycle still has a few noteworthy points.Click below (subscribers only) for the full article from this week's KernelPage.

Firefox 48 is out, featuring process separation (e10s) for some users,mandatory add-ons signatures, stable WebExtensions, enhanced downloadprotection, and more. See the releasenotes for details.

GNOME Maps recently ran into a tile problem (LWN article) when a service it relied on shutdown. Jonas Danielsson reportsthat Maps will be getting tiles from Mapbox. "We access Mapbox through a GNOME based redirect, so that we could redirect to something else if a similar situation would arise again."

Evan Klitzke explainswhy Uber Engineering moved away from Postgresql. "The earlyarchitecture of Uber consisted of a monolithic backend application writtenin Python that used Postgres for data persistence. Since that time, thearchitecture of Uber has changed significantly, to a model of microservices and new dataplatforms. Specifically, in many of the cases where we previously usedPostgres, we now use Schemaless, a noveldatabase sharding layer built on top of MySQL. In this article, we’llexplore some of the drawbacks we found with Postgres and explain thedecision to build Schemaless and other backend services on top ofMySQL." (Thanks to Dimitri John Ledkov)

The US Federal Communications Commission (FCC) has announced a settlement with network-hardware manufacturer TP-Link, covering both the company's non-compliance with FCC transmission-power regulations and the company's plan to lock-out third-party firmware—including open-source firmware projects like OpenWrt. "While manufacturers of Wi-Fi routers must ensure reasonable safeguards toprotect radio parameters, users are otherwise free to customize their routers and we support TP-Link’s commitment to work with the open-source community and Wi-Fi chipset manufacturers to enable third-party firmware on TP-Link routers." Under the settlement agreement, TP-Link will pay a $200,000 fine for shipping WiFi routers that could be configured to run above the permitted power limits, but it will also have to cooperate with open-source firmware projects to make sure they remain installable. TP-Link had moved to block user-installed firmware in March as its first attempt to satisfy the FCC's complaint about non-compliant power settings.

The CFP deadline for the 2017 linux.conf.au (January 16-20, Hobart) is August 5; the organizers are warning that, contrary to the usual LCAtradition, that deadline will not be extended this year. So anybodywho thinks they may want to speak at LCA should get going on a proposal;see the CFP page forinstructions.

OpenSSH 7.3 is out. This release fixes a number of security issues (mostlyrelated to timing attacks) and adds a handful of new minor features. Thedevelopers also warn that RSA keys less than 1024 bits will be refused in anear-future release.

The Androidsecurity bulletin for July covers the issues that have recently beenfixed for supported Android devices. "The most severe of theseissues is a Critical security vulnerability that could enable remote codeexecution on an affected device through multiple methods such as email, webbrowsing, and MMS when processing media files." There are severaldozen CVE numbers listed overall, including 31 Qualcomm-specificvulnerabilities dating as far back as 2013.

Jehan Pagès writesabout the current GIMP development release and the plan from here."I want to imagine a future where most big graphics programintegrates GEGL, where Blender for instance would have GEGL as the newimplementation of nodes, with image processing graphs which can beexchanged between programs, where darktable would share buffers with GIMPso that images can be edited in one program and updated in real time in theother, and so on. Well of course the short/mid-term improvements will benon-destructive editing with live preview on high bit depth images, andthat’s already awesomely cool right?" See also theannouncement for more information on the GIMP 2.9.4 release.

On his blog, Gmane creator and maintainer Lars Magne Ingebrigtsen warns that the email-to-news (and web) gateway may be disappearing soon. The site, which is hosted by his employer, has been under a distributed denial of service (DDoS) attack for the last few weeks, but there are other problems as well. "And now the DDoS stuff, which I have no idea why is happening, but I can only assume that somebody is angry about something.Probably me being a wise ass.So… it’s been 14 years… I’m old now. I almost threw up earlier tonight because I’m so stressed about the situation. I should retire and read comic books and watch films. Oh, and the day job. Work, work, work. Oh, and Gnus.I’m thinking about ending Gmane, at least as a web site. Perhaps continue running the SMTP-to-NNTP bridge? Perhaps not? I don’t want to make 20-30K mailing lists start having bouncing addresses, but I could just funnel all incoming mail to /dev/null, I guess…" The site, which has been relied on by many (including LWN) since it started in 2002, is down now and it appears to be unclear when (or if) it will be back.

A few years ago, the hardware vendor Yubico made a bit of a splashwhen it introduced its YubiKey line of inexpensive hardware securitytokens powered by open-source software. With its most recent productrelease, however, Yubico has dropped open source and started deploying onlyproprietary software in its devices. Consequently, many communitymembers have started looking for a viable replacement that will adhereto open-source principles. At present, one of the leading contendersfor Yubico's departed customers is Nitrokey, which manufactures a lineof hardware tokens capable of generating one-time passwords (OTPs),storing and using OpenPGP keys, and several other features. Thedevices made by Nitrokey run open-source software and are open hardwareas well.

Shari Steele has posted a statement from theTor project on the results of an investigation into the allegations ofharassment (and worse) within Tor and how the project will respond. "I ampleased, therefore, to announce that both the Tor Project and the Torcommunity are taking active steps to strengthen our ability to handleproblems of unprofessional behavior. Specifically, the Tor Project hascreated an anti-harassment policy, a conflicts of interest policy,procedures for submitting complaints, and an internal complaint reviewprocess. They were recently approved by Tor’s board of directors, and theywill be rolled out internally this week."

Harald Sitter reportson a discussion at recent sprint focused on making Snap packaging usefulfor KDE. "Shipping things users can use on Linux has been a pain in the rearsince forever and these bundles are meant to change that. As such weas KDE should have a strong interest and presence in this field in thehopes of shaping a future that is useful to us. After all, we are oneof the biggest source distributors, and the primary reason we don'talso offer generic binary packages of our applications is because thisnever scaled and was altogether terrible to pull off from a KDE pointof view." He and Scarlett Clark are working on somehigh level mass automation of snap building on top of KDE Neon's existingdeb binaries. (Thanks to Jos van den Oever)

At his blog, Matthias Clasen exploresthe recent enhancements to the the classic GNU gettext utility.Thanks in large part to new maintainer Daiki Ueno, gettext nowunderstands many more file formats—thus enabling developers to easilyextract strings from a wide variety of source files for translation.In addition to programming languages, Clasen notes, gettextunderstands .desktop files, GSettings schemas, GtkBuilder ui files,and Appdata files. "If you don’t want to wait for your favorite format to come with built-in its support, you can also include its files with your application; gettext will look for such files in $XDG_DATA_DIRS/gettext/its/."

The Electronic Frontier Foundation (EFF) has announced that it is suing the US government over provisions in the Digital Millennium Copyright Act (DMCA). The suit has been filed on behalf of Andrew "bunnie" Huang, who has a blog post describing the reasons behind the suit. The EFF also explained why these DMCA provisions should be ruled unconstitutional:"These provisions—contained in Section 1201 of the DMCA—make it unlawful for people to get around the software that restricts access to lawfully-purchased copyrighted material, such as films, songs, and the computer code that controls vehicles, devices, and appliances. This ban applies even where people want to make noninfringing fair uses of the materials they are accessing. Ostensibly enacted to fight music and movie piracy, Section 1201 has long served to restrict people’s ability to access, use, and even speak out about copyrighted materials—including the software that is increasingly embedded in everyday things. The law imposes a legal cloud over our rights to tinker with or repair the devices we own, to convert videos so that they can play on multiple platforms, remix a video, or conduct independent security research that would reveal dangerous security flaws in our computers, cars, and medical devices. It criminalizes the creation of tools to let people access and use those materials."

Congratulations are due to Alan Cox, who was awardedan honorary degree by Swansea University for his work with Linux."Alan started working on Version 0. There were bugs and problems hecould correct. He put Linux on a machine in the Swansea University computernetwork, which revealed many problems in networking which he sorted out;later he rewrote the networking software. Alan brought to Linux softwareengineering discipline: Linux software releases that were tested, correctedand above all stable. On graduating, Alan worked at Swansea University, setup the UK Linux server and distributed thousands of systems."

Benjamin Smedberg writesthat the Firefox browser will soon start taking a more active approach tothe elimination of Flash content. "Starting in August, Firefox willblock certain Flash content that is not essential to the user experience,while continuing to support legacy Flash content. These and future changeswill bring Firefox users enhanced security, improved battery life, fasterpage load, and better browser responsiveness."

The Register reportsthat longtime Tor contributor Lucky Green is quitting and closing down thenode and bridge authority he operates. "Practically, it's a bigdeal. Bridge Authorities are part of the infrastructure that lets users getaround some ISP-level blocks on the network (not, however, defeating deeppacket inspection). They're also incorporated in the Tor code, meaning thatto remove a Bridge Authority is going to need an update." Theshutdown is scheduled for August 31. (Thanks to Nomen Nescio)

The Software Freedom Conservancy is one of the few organizations involvedin GPL enforcement, and it has publishedprinciples regarding enforcement practices that seek compliance and notfinancial penalties. Bradley Kuhn and Karen Sandler urgeothers doing GPL enforcement to follow principles set forth by theSFC. "One impetus in drafting the Principles was our discovery ofongoing enforcement efforts that did not fit with the GPL enforcementcommunity traditions and norms established for the last twodecades. Publishing the previously unwritten guidelines has quicklyseparated the wheat from the chaff. Specifically, we remain aware ofmultiple non-community-oriented GPL enforcement efforts, where none ofthose engaged in these efforts have endorsed our principles nor pledged toabide by them. These “GPL monetizers”, who trace their roots to nefariousbusiness models that seek to catch users in minor violations in order tosell an alternative proprietary license, stand in stark contrast to thework that Conservancy, FSF and gpl-violations.org have done foryears." The actions of one individual prompted the netfilterproject to make a statement endorsing the principles, which we covered earlier this month.

Version 1.0 of the QtWebBrowser has been released.Qt WebBrowser is a browser for embedded devices developed using thecapabilities of Qt and Qt WebEngine. "The browser is optimized for embedded touch displays (running Linux), but you can play with it on the desktop platforms, too! Just make sure that you have Qt WebEngine, Qt Quick, and Qt VirtualKeyboard installed (version 5.7 or newer). For optimal performance on embedded devices you should plan for hardware-accelerated OpenGL, and around 1 GiByte of memory for the whole system. Anyhow, depending on your system configuration and the pages to be supported there is room for optimization."
