[$] XFS: There and back ... and there again?
In a thought-provoking—and characteristically amusing—talk at the Vault conference,Dave Chinner looked at the history of XFS, its current status, and where the filesystem may be heading.In keeping with the title of the talk (shared by this article), he sees parallels in what drove the original development of XFS and what will bedriving new filesystems.Chinner's vision of the future for today's filesystems, and not justof XFS, may be a bit surprising or controversial—possibly both.

[$] Development activity in LibreOffice and OpenOffice
The LibreOffice project was announced withgreat fanfare in September 2010. Nearly one year later, the OpenOffice.orgproject (from which LibreOffice was forked) wascut loose from Oracle andfound a new home as an Apache project. It is fair to say that the rivalrybetween the two projects in the time since then has been strong.Predictions that one project or the other would fail have not been borneout, but that does not mean that the two projects are equally successful.A look at the two projects' development communities reveals someinteresting differences.Click below (subscribers only) for the full article.

Meet Cyanogen, The Startup That Wants To Steal Android From Google (Forbes)
Forbes takesa look at Cyanogen, and its prospects in the phone market."Cyanogen has a chance to snag as many as 1 billion handsets, morethan the total number of iPhones sold to date, according to someanalysts. Fifty million people already run Cyanogen on their phones, thecompany says. Most went through the hours-long process of erasing anAndroid phone and rebooting it with Cyanogen. [Kirt] McMaster is now persuading a growing list of phone manufacturers to make devices with Cyanogen built in, rather than Google’s Android. Their phones are selling out in record time. Analysts say each phone could bring Cyanogen a minimum of $10 in revenue and perhaps much more."
Van de Ven: Deprecating old crypto
Worth a read: this postfrom Arjan van de Ven on the difficulty of removing old, insecurecryptographic algorithms from a Linux distribution. "But more, andthis is a call to action: If you're working on an open source project thatuses crypto, please please don't opencode crypto algorithm usage.

Google: Maintaining digital certificate security
It seems it was about time for another certificate authority horror story;the Google Online Security Blog duly delivers."CNNIC responded on the 22nd to explain that they had contracted withMCS Holdings on the basis that MCS would only issue certificates fordomains that they had registered. However, rather than keep the private keyin a suitable HSM, MCS installed it in a man-in-the-middle proxy. Thesedevices intercept secure connections by masquerading as the intendeddestination and are sometimes used by companies to intercept theiremployees’ secure traffic for monitoring or legal reasons. The employees’computers normally have to be configured to trust a proxy for it to be ableto do this. However, in this case, the presumed proxy was given the fullauthority of a public CA, which is a serious breach of the CAsystem."
Windows 10 to make the Secure Boot alt-OS lock out a reality (Ars Technica)
Ars Technica is one of several news outlets to report on a change announced in Microsoft's Windows 10 plans. Though the headlines (including Ars Technica's) paint a rather bleak scenario, the details are not as clear-cut. The UEFI "Secure Boot" mechanism was introduced with Windows 8, at which time Microsoft's OEM-certification rules mandated that hardware must include a means for the local user to disable Secure Boot. The Windows 10 certification rules does not include the mandated disable switch. Writes Peter Bright: "Should this stand, we can envisage OEMs building machines that will offer no easy way to boot self-built operating systems, or indeed, any operating system that doesn't have appropriate digital signatures. This doesn't cut out Linux entirely—there have been some collaborations to provide Linux boot software with the 'right' set of signatures, and these should continue to work—but it will make it a lot less easy." Note, also, that the only source for this story appears to be a presentation from a Microsoft event in Shenzhen, China. Bright adds that he has contacted Microsoft seeking clarification, but has so far received no reply.

Snellman: On open sourcing existing code
Juho Snellman has an interesting treatise on the oft-overlooked challenges that face developers attempting to release an existing, proprietary codebase under open-source terms. "As soon as you get outside of the "one self-contained file or directory" level of complexity, the threshold for releasing code becomes much higher. And likewise every change to a program that was made in order to open source it will make it less likely that the two versions can really be kept in sync in the long term. In this case the core code is maybe 2k-3k lines and won't require much work. It's all the support infrastructure that's going to be an issue." Snellman also reflects on possible strategies for writing internal code that may some day be released to the public.

Docker security in the future (Opensource.com)
Over at Opensource.com, Daniel Walsh writes about applying various Linux security technologies to Docker containers. In the article, he looks at using user namespaces and seccomp filters to provide better security for Docker. "One of the problems with all of the container separation modes described here and elsewhere is that they all rely on the kernel for separation. Unlike air gapped computers, or even virtual machines, the processes within the container can talk directly to the host kernel. If the host kernel has a kernel vulnerability that a container can access, they might be able to disable all of the security and break out of the container.The x86_64 Linux kernel has over 600 system calls, a bug in any one of which could lead to a privilege escalation. Some of the system calls are seldom called, and should be eliminated from access within the container."

[$] Reservations for must-succeed memory allocations
When the schedulefor the 2015 Linux Storage, Filesystem, and Memory Management Summit waslaid out, its authors optimistically set aside 30 minutes on the first dayfor the thorny issue of memory-allocation problems in low-memorysituations. That session (covered here)didn't get past the issue of whether small allocations should be allowed tofail, so the remainder of the discussion, focused on finding bettersolutions for the problem of allocations that simply cannot fail, waspushed into a plenary session on the second day.With this article, LWN's coverage of the memory-management track at LSFMM2015 is complete; sessions from the filesystems track are being added aswell.

The GNU Manifesto Turns Thirty (New Yorker)
The New Yorker notesthe 30th anniversary of the GNU Manifesto. "Stallman was one of the first to grasp that, if commercial entitieswere going to own the methods and technologies that controlled computers,then computer users would inevitably become beholden to thoseentities. This has come to pass, and in spades. Most computer users havebecome dependent on proprietary code provided by companies like Apple,Facebook, and Google, the use of which comes with conditions we may notcondone or even know about, and can’t control; we have forfeited thefreedom to adapt such code according to our needs, preferences, andpersonal ethics."
