OpenSource.com Test-Drives Linux Distros From 1993 To 2003 (opensource.com) 80

An anonymous reader quotes OpenSource.com: A unique trait of open source is that it's never truly EOL (End of Life). The disc images mostly remain online, and their licenses don't expire, so going back and installing an old version of Linux in a virtual machine and getting a precise picture of what progress Linux has made over the years is relatively simple... Whether you're new to Linux, or whether you're such an old hand that most of these screenshots have been more biographical than historical, it's good to be able to look back at how one of the largest open source projects in the world has developed. More importantly, it's exciting to think of where Linux is headed and how we can all be a part of that, starting now, and for years to come.
The article looks at seven distros -- Slackware 1.01 (1993), Debian 0.91 (1994), Jurix/S.u.S.E. (1996), SUSE 5.1 (1998), Red Hat 6.0 (1999), Mandrake 8.0 (2001), and Fedora 1 (2003). Click through for some of the highlights.

Canonical Needs Your Help Transitioning Ubuntu Linux From Unity To GNOME (ubuntu.com) 111

BrianFagioli quotes BetaNews: On August 24 and 25, the Ubuntu Desktop team will be holding a "Fit and Finish Sprint," where they will aggressively test GNOME. Canonical is also asking the Ubuntu community to help with this process. In other words, you might be able to assist with making Artful Aardvark even better.

What makes this particularly cool, however, is that Canonical will be selecting some community members to visit its London office on August 24 between 4 pm and 9 pm. "Over the two days we'll be scrutinizing the new GNOME Shell desktop experience, looking for anything jarring/glitchy or out of place," says Alan Pope, Community Manager. "We'll be working on the GTK, GDM and desktop theme alike, to fix inconsistencies, performance, behavioral or visual issues. We'll also be looking at the default key bindings, panel color schemes and anything else we discover along the way."

A few caveats: Canonical won't pay anyone's travel expenses to London, and "Ideally we're looking for people who are experienced in identifying (and fixing) theme issues, CSS experts and GNOME Shell / GTK themers."

AMD Confirms Linux 'Performance Marginality Problem' On Ryzen (phoronix.com) 120

An anonymous reader writes: Ryzen customers experiencing segmentation faults under Linux when firing off many compilation processes have now had their problem officially acknowledged by AMD. The company describes it as a "performance marginality problem" affecting some Ryzen customers and only on Linux. AMD confirmed Threadripper and Epyc processors are unaffected; they will be dealing with the issue on a customer-by-customer basis, and their future consumer products will see better Linux testing/validation. Ryzen customers believed to be affected by the problem can contact AMD Customer Care. Michael Larabel writes via Phoronix: "With the Ryzen segmentation faults on Linux they are found to occur with many, parallel compilation workloads in particular -- certainly not the workloads most Linux users will be firing off on a frequent basis unless intentionally running scripts like ryzen-test/kill-ryzen. As I've previously written, my Ryzen Linux boxes have been working out great except in cases of intentional torture testing with these heavy parallel compilation tasks. [AMD's] analysis has also found that these Ryzen segmentation faults aren't isolated to a particular motherboard vendor or the like, contrary to rumors/noise online due to the complexity of the problem."

OpenSSL Support In Debian Unstable Drops TLS 1.0/1.1 Support (debian.org) 76

An anonymous reader writes: Debian Linux "sid" is deprecating TLS 1.0 Encryption. A new version of OpenSSL has been uploaded to Debian Linux unstable. This version disables the TLS 1.0 and 1.1 protocol. This currently leaves TLS 1.2 as the only supported SSL/TLS protocol version. This will likely break certain things that for whatever reason still don't support TLS 1.2. I strongly suggest that if it's not supported that you add support for it, or get the other side to add support for it. OpenSSL made a release 5 years ago that supported TLS 1.2. The current support of the server side seems to be around 90%. I hope that by the time Buster releases the support for TLS 1.2 will be high enough that I don't need to enable them again. This move caused some concern among Debian users and sysadmins. If you are running Debian Unstable on server tons of stuff is going to broken cryptographically. Not to mention legacy hardware and firmware that still uses TLS 1.0. On the client side (i.e. your users), you need to use the latest version of a browser such as Chrome/Chromium and Firefox. The Older version of Android (e.g. Android v5.x and earlier) do not support TLS 1.2. You need to use minimum iOS 5 for TLS 1.2 support. Same goes with SMTP/mail servers, desktop email clients, FTP clients and more. All of them using old outdated crypto.

This move will also affect for Android 4.3 users or stock MS-Windows 7/IE users (which has TLS 1.2 switched off in Internet Options.) Not to mention all the mail servers out there running outdated crypto.

Red Hat Acquires Data-Cleaning Company Permabit (fortune.com) 85

An anonymous reader quotes Fortune: Business software company Red Hat said on Monday that it is acquiring the technology assets of Permabit, a small company that specializes in cleaning up corporate data to make storage more efficient and data access faster. Terms of the deal were not disclosed but a Red Hat spokesman said 16 people from Permabit will be joining that company...

While the conventional wisdom is that data storage is cheap, it is not free. And with companies turning to more expensive flash storage, it saves money to remove redundant data, said Richard Fichera, vice president and principal analyst at Forrester Research... Red Hat, which sells a version of the Linux operating system used by many Fortune 500 companies, also offers its own storage software. And, it wants to become a more formidable challenger in data storage, a goal that can be furthered by buying Permabit's technology, Fichera said.

Slashdot reader See Attached points out that this week Red Hat also released RHEL 7.4, which introduces support for Network Bound Disk Encryption (NBDE) and system protection against intrusive USB devices.

Linux Kernel Hardeners Grsecurity Sue Open Source's Bruce Perens (theregister.co.uk) 307

An anonymous reader shares a report from The Register: In late June, noted open-source programmer Bruce Perens [a longtime Slashdot reader] warned that using Grsecurity's Linux kernel security could invite legal trouble. "As a customer, it's my opinion that you would be subject to both contributory infringement and breach of contract by employing this product in conjunction with the Linux kernel under the no-redistribution policy currently employed by Grsecurity," Perens wrote on his blog. The following month, Perens was invited to court. Grsecurity sued the open-source doyen, his web host, and as-yet-unidentified defendants who may have helped him draft that post, for defamation and business interference. Grsecurity offers Linux kernel security patches on a paid-for subscription basis. The software hardens kernel defenses through checks for common errors like memory overflows. Perens, meanwhile, is known for using the Debian Free Software Guidelines to draft the Open Source Definition, with the help of others.

Grsecurity used to allow others to redistribute its patches, but the biz ended that practice for stable releases two years ago and for test patches in April this year. It offers its GPLv2 licensed software through a subscription agreement. The agreement says that customers who redistribute the code -- a right under the GPLv2 license -- will no longer be customers and will lose the right to distribute subsequent versions of the software. According to Perens, "GPL version 2 section 6 explicitly prohibits the addition of terms such as this redistribution prohibition." A legal complaint (PDF) filed on behalf of Grsecurity in San Francisco, California, insists the company's software complies with the GPLv2. Grsecurity's agreement, the lawsuit states, only applies to future patches, which have yet to be developed. Perens isn't arguing that the GPLv2 applies to unreleased software. Rather, he asserts the GPLv2, under section 6, specifically forbids the addition of contractual terms.

Ubuntu Will Revert Window Controls To the Right-Hand Side in Next Release (neowin.net) 171

Following a survey carried out last month, Ubuntu will begin shipping with the minimise, maximise, and close buttons on the right-hand side of windows. From a report: In the survey 46.2% of people said they prefer their window controls on the left-hand side and 53.8% said they prefer them on the right. The decision comes after seven years of window controls being on the left, at the time it had plenty of detractors but Ubuntu founder, Mark Shuttleworth, maintained that the controls needed shifting to the left because they'd be in the way of the then newly introduced window indicators.

It Will Take Fedora More Releases To Switch Off Python 2 (phoronix.com) 94

An anonymous reader quotes Phoronix: Finalizing Fedora's switch from Python 2 to Python 3 by default is still going to take several more Fedora release cycles and should be done by the 2020 date when Python 2 will be killed off upstream. While much of Fedora's Python code is now compatible with Py3, the /usr/bin/python still points to Python 2, various python-* packages still mean Python 2... The end game is to eventually get rid of Python 2 from Fedora but that is even further out.
Fedora is now gathering feedback on a Wiki page explaining the switch.

Microsoft Further Pledges Linux Loyalty, Joins Cloud Native Computing Foundation (betanews.com) 109

BrianFagioli quotes BetaNews: Today, Microsoft further pledges its loyalty to Linux and open source by becoming a platinum member of the Cloud Native Computing Foundation. If you aren't familiar, the CNCF is a part of the well-respected Linux Foundation (of which Microsoft is also a member). With the Windows-maker increasingly focusing its efforts on the cloud -- and profiting from it -- this seems like a match made in heaven. In fact, Dan Kohn, Executive Director of the foundation says, "We are honored to have Microsoft, widely recognized as one of the most important enterprise technology and cloud providers in the world, join CNCF as a platinum member."

"CNCF is a part of the Linux Foundation, which helps govern for a wide range of cloud-oriented open source projects, such as Kubernetes, Prometheus, OpenTracing, Fluentd, Linkerd, containerd, Helm, gRPC, and many others," says John Gossman Azure Architect, Microsoft. "Since we joined the Linux Foundation last year, and now have decided to expand that relationship to CNCF membership as a natural next step to invest in open source communities and code at multiple levels, especially in the area of containers."

The announcement notes that Microsoft has already been contributing code to the Kubernetes project, "as well as running Kubernetes as part of the Azure Container Service."

Systemd Named 'Lamest Vendor' At Pwnie Security Awards (theregister.co.uk) 436

Long-time Slashdot reader darkpixel2k shares a highlight from the Black Hat USA security conference. The Register reports: The annual Pwnie Awards for serious security screw-ups saw hardly anyone collecting their prize at this year's ceremony in Las Vegas... The gongs are divided into categories, and nominations in each section are voted on by the hacker community... The award for best server-side bug went to the NSA's Equation Group, whose Windows SMB exploits were stolen and leaked online this year by the Shadow Brokers...

And finally, the lamest vendor response award went to Systemd supremo Lennart Poettering for his controversial, and perhaps questionable, handling of the following bugs in everyone's favorite init replacement: 5998, 6225, 6214, 5144, and 6237... "Where you are dereferencing null pointers, or writing out of bounds, or not supporting fully qualified domain names, or giving root privileges to any user whose name begins with a number, there's no chance that the CVE number will referenced in either the change log or the commit message," reads the Pwnie nomination for Systemd, referring to the open-source project's allergy to assigning CVE numbers. "But CVEs aren't really our currency any more, and only the lamest of vendors gets a Pwnie!"

CSO has more coverage -- and presumably there will eventually be an official announcement up at Pwnies.com.

Microsoft's 'Windows Subsystem For Linux' Finally Leaves Beta (microsoft.com) 163

An anonymous reader quotes Microsoft's Developer blog: Early adopters on the Windows Insider program will notice that Windows Subsystem for Linux is no longer marked as a beta feature as of Insider build 16251. This will be great news for those who've held-back from employing WSL as a mainline toolset: You'll now be able to leverage WSL as a day-to-day developer toolset, and become ever more productive when building, testing, deploying, and managing your apps and systems on Windows 10... What will change is that you will gain the added advantage of being able to file issues on WSL and its Windows tooling via our normal support mechanisms if you want/need to follow a more formal issue resolution process. You can also provide feedback via Windows 10 Feedback Hub app, which delivers feedback directly to the team.
Microsoft points out that distro-publishers are still responsible for supporting and fixing the internals of their distros -- and they have no plans to support X/GUI apps or desktops. And of course, Linux files are not currently accessible from Windows -- though Microsoft says they're working on a fix.

OpenMoko: Ten Years After (vanille.de) 48

Michael Lauer, member of the core team at OpenMoko, a project that sought to create a family of open source mobile phones -- which included the hardware specs and the Linux-based OS -- has shared the inside story of what the project wanted to do and why it failed. From his blog post: For the 10th anniversary since the legendary OpenMoko announcement at the "Open Source in Mobile" (7th of November 2006 in Amsterdam), I've been meaning to write an anthology or -- as Paul Fertser suggested on #openmoko-cdevel -- an obituary. I've been thinking about objectively describing the motivation, the momentum, how it all began and -- sadly -- ended. I did even plan to include interviews with Sean, Harald, Werner, and some of the other veterans. But as with oh so many projects of (too) wide scope this would probably never be completed. As November 2016 passed without any progress, I decided to do something different instead. Something way more limited in scope, but something I can actually finish. My subjective view of the project, my participation, and what I think is left behind: My story, as OpenMoko employee #2. On top of that you will see a bunch of previously unreleased photos (bear with me, I'm not a good photographer and the camera sucked as well). [....] Right now my main occupation is writing software for Apple's platforms -- and while it's nice to work on apps using a massive set of luxury frameworks and APIs, you're locked and sandboxed within the software layers Apple allows you. I'd love to be able to work on an open source Linux-based middleware again. However, the sad truth is that it looks like there is no business case anymore for a truly open platform based on custom-designed hardware, since people refuse to spend extra money for tweakability, freedom, and security. Despite us living in times where privacy is massively endangered.

FreeBSD, which is based off of the historical BSD Unix in which TCP/IP was developed on from the University of California at Berkeley, has been updated. It does not include systemd nor PulseAudio and is popular in many web server installations and networking devices. FreeBSD 11.1 is out with improvements in UEFI and Amazon cloud support in addition to updated userland programs. EFI improvements including a new utility efivar(8) to manage UEFI variables, EFI boot from TFTP or NFS, as well as Microsoft Hyper-V UEFI and Secure Boot for generation 2 virtual machines for both Windows Server and Windows 10 Professional hosts. FreeBSD 11.1 also has extended support Amazon Cloud features. A new networking stack for Amazon has been added with the ena(4) driver, which adds support for Amazon EC2 platform. This also adds support for using Amazon EC2 NFS shares and support for the Amazon Elastic Filesystem for NFS. For application updates, FreeBSD 11.1 Clang, LLVM, LLD, LLDB, and libc++ to version 4.0.0. ZFS has been updated too with a new zfsbootcfg with minor performance improvements. Downloads are here which include Sparc, PowerPC, and even custom SD card images for Raspberry Pi, Beagle-bone and other devices.

DNS Lib Underscore Bug Bites Everyone's Favorite Init Tool, Blanks Netflix (theregister.co.uk) 292

Reader OneHundredAndTen writes and shares a report: Systemd doing what it does best. From a report on The Register: A few Penguinistas spent a weekend working out why they can't get through to Netflix from their Linux machines, because when they tried, their DNS lookups failed. The issue emerged over the weekend, when Gentoo user Dennis Schridde submitted a bug report to the Systemd project. Essentially, he described a failure within systemd-resolve, a Systemd component that turns human-readable domain names into IP addresses for software, like web browsers, to connect to. The Systemd resolver couldn't look up Netflix's servers for Schridde's web browser, according to the report. In his detailed post, Schridde said he expected this to happen: ipv6_1-cxl0-c088.1.lhr004.ix.nflxvideo.net gets resolved to 37.77.187.142 or 2a00:86c0:5:5::142. When in reality, that wasn't happening, so Netflix couldn't be reached on his box. His speculation that libidn2, which adds internationalised domain names support to the resolver, was at fault turned out to be accurate. Rebuilding Systemd without that library cleared the problem.

Debian, Gnome Patched 'Bad Taste' VBScript-Injection Vulnerabilities (neowin.net) 72

Slashdot reader KiloByte warned us about new exploit for .MSI files named "bad taste". Neowin reports: A now-patched vulnerability in the "GNOME Files" file manager was recently discovered which allowed hackers to create dodgy MSI files which would run malicious VBScript code on Linux... Once Nils Dagsson Moskopp discovered the bug, he reported it to the Debian Project which fixed it very rapidly. The GNOME Project also patched the gnome-exe-thumbnailer file which is responsible for parsing MSI and EXE files inside the GNOME Files app... If you run a Linux distribution with the GNOME desktop it's advisable to run the update manager and check for updates as soon as possible before you become affected by this critical vulnerability.

Linus Torvalds Now Reviews Gadgets On Google+ (zdnet.com) 51

An anonymous reader quotes ZDNet: If you know anything about Linus Torvalds, you know he's the mastermind and overlord of Linux. If you know him at all well, you know he's also an enthusiastic scuba diver and author of SubSurface, a do-it-all dive log program. And, if you know him really well, you'd know, like many other developers, he loves gadgets. Now, he's starting his own gadget review site on Google+: Working Gadgets...

"[W]hile waiting for my current build to finish, I decided to write a note about some of the gadgets I got that turned out to work, rather than all the crazy crap that didn't. Because while 90% of the cool toys I buy aren't all that great, there's still the ones that actually do live up to expectations. So the rule is: no rants. Just good stuff. Because this is about happy gadgets."

So far Linus has reviewed an automatic cat litter box, a scuba diving pressure regulator, and a Ubiquiti UniFi Wi-Fi access point that complements his Google WiFi mesh network.

Linus will be great at this. Just last week I saw him recommending a text editor.

Slackware, Oldest Linux Distro Still In Active Development, Turns 24 70

sombragris writes: July 17 marked the 24th anniversary of Slackware Linux, the oldest GNU/Linux still in active development, being created in 1993 by Patrick Volkerding, who still serves as its BDFL. Version 14.2 was launched last year, and the development version (Slackware-current) currently offers kernel 4.9.38, gcc 7.1, glibc 2.25, mesa 17.1.5, and KDE and Xfce as official desktops, with many others available as 3rd party packages. Slackware is also among the Linux distributions which have not adopted systemd as its init system; instead, it uses a modified BSD init which is quite simple and effective. Slackware is known to be a solid, stable and fast setup, with easy defaults which is appreciated by many Linux users worldwide. Phoronix has a small writeup noting the anniversary and there's also a nice reddit thread.

In Which Linus Torvalds Makes An 'Init' Joke (lkml.org) 359

Long-time Slashdot reader jawtheshark writes: In a recent Linux Kernel Mailing List post, Linux Torvalds finishes his mail with a little poke towards a certain init system. It is a very faint criticism, compared to his usual style. While Linus has no direct influence on the "choices" of distro maintainers, his opinion is usually valued.
In a discussion about how to set rlimit default values for setuid execs, Linus concluded his email by writing, "And yes, a large part of this may be that I no longer feel like I can trust "init" to do the sane thing. You all presumably know why."

Bruce Perens Warns Grsecurity Breaches the Linux Kernel's GPL License (perens.com) 474

Bruce Perens co-founded the Open Source Initiative with Eric Raymond. Now he's sharing a "strong opinion" that companies should avoid the Grsecurity security patch for the Linux kernel "because it presents a contributory infringement and breach of contract risk." Slashdot reader NewGnu shared Bruce's comments: [I]t would fail a fair-use test... Because of its strongly derivative nature of the kernel, it must be under the GPL version 2 license, or a license compatible with the GPL and with terms no more restrictive than the GPL. Earlier versions were distributed under GPL version 2... My understanding from several reliable sources is that customers are verbally or otherwise warned that if they redistribute the Grsecurity patch, as would be their right under the GPL, that they will be assessed a penalty: they will no longer be allowed to be customers, and will not be granted access to any further versions of Grsecurity. GPL version 2 section 6 explicitly prohibits the addition of terms such as this redistribution prohibition...

This is tantamount to the addition of a term to the GPL prohibiting distribution or creating a penalty for distribution. GPL section 6 specifically prohibits any addition of terms. Thus, the GPL license, which allows Grsecurity to create its derivative work of the Linux kernel, terminates, and the copyright of the Linux Kernel is infringed. The contract from the Linux kernel developers to both Grsecurity and the customer which is inherent in the GPL is breached.

Perens advises companies to discuss his position with their attorneys, adding "In the public interest, I am willing to discuss this issue with companies and their legal counsel, under NDA, without charge."

WikiLeaks Unveils CIA Implants That Steal SSH Credentials From Windows, Linux PCs (thehackernews.com) 140

An anonymous reader quotes a report from The Hacker News: WikiLeaks has today published the 15th batch of its ongoing Vault 7 leak, this time detailing two alleged CIA implants that allowed the agency to intercept and exfiltrate SSH (Secure Shell) credentials from targeted Windows and Linux operating systems using different attack vectors. Secure Shell or SSH is a cryptographic network protocol used for remote login to machines and servers securely over an unsecured network. Dubbed BothanSpy -- implant for Microsoft Windows Xshell client, and Gyrfalcon -- targets the OpenSSH client on various distributions of Linux OS, including CentOS, Debian, RHEL (Red Hat), openSUSE and Ubuntu. Both implants steal user credentials for all active SSH sessions and then sends them to a CIA-controlled server.

OpenBSD Will Get Unique Kernels On Each Reboot (bleepingcomputer.com) 162

An anonymous reader quotes a report from Bleeping Computer: A new feature added in test snapshots for the upcoming OpenBSD 6.2 release will create a unique kernel every time an OpenBSD user reboots or upgrades his computer. This feature is named KARL -- Kernel Address Randomized Link -- and works by relinking internal kernel files in a random order so that it generates a unique kernel binary blob every time. Currently, for stable releases, the OpenBSD kernel uses a predefined order to link and load internal files inside the kernel binary, resulting in the same kernel for all users. Developed by Theo de Raadt, KARL will work by generating a new kernel binary at install, upgrade, and boot time. If the user boots up, upgrades, or reboots his machine, the most recently generated kernel will replace the existing kernel binary, and the OS will generate a new kernel binary that will be used on the next boot/upgrade/reboot, constantly rotating kernels on reboots or upgrades. KARL should not be confused with ASLR -- Address Space Layout Randomization -- a technique that randomizes the memory address where application code is executed, so exploits can't target a specific area of memory where an application or the kernel is known to run. A similar technique exists for randomizing the memory location where the kernel loads -- called KASLR. The difference between the two is that KARL loads a different kernel binary in the same place, while KASLR loads the same binary in random locations. Currently Linux and Windows only support KASLR.

Linux Is Not As Safe As You Think (betanews.com) 237

BrianFagioli writes via BetaNews: Would you be surprised if I told you that threat methods for Linux increased an astonishing 300 percent in 2016, while Microsoft's operating systems saw a decrease? Well, according to a new report, that is true. Does this mean Linux is unsafe? No way, Jose! There are some important takeaways here. Microsoft's Windows operating systems are still the most targeted platforms despite the year over year decline -- far beyond Linux. Also, just because there is an increase in malware attack methods doesn't necessarily mean that more systems will be infected. Let us not forget that it is easier to find a vulnerability with open source too; Microsoft largely uses closed source code. "At the end of November, criminals with other variants of the same Linux malware unleashed devastating attacks against DSL routers of Telekom customers. 900,000 devices were taken down. In October, the Mirai code appeared freely available on the Internet. Since then, the AV-TEST systems have been investigating an increasing number of samples with spikes at the end of October, November and beginning of December," says AV Test of the Mirai malware. "Other Linux malware, such as the Tsunami backdoor, has been causing trouble for several years now and can be easily modified for attacks against IoT devices. The detection systems of AV-TEST first detected the Tsunami malicious code in the year 2003. Although, at that time, practically no IoT devices existed, the Linux backdoor already offered attack functions which even today would be suitable for virtually unprotected attacks on routers: In this manner, Tsunami can download additional malicious code onto infected devices and thus make devices remote controllable for criminals. But the old malware can also be used for DDoS attacks. The Darlloz worm, known since 2013, as well as many other Linux and Unix malware programs, have similar attack patterns which AV-TEST has been detecting and analyzing for years."

'Severe' Systemd Bug Allowed Remote Code Execution For Two Years (itwire.com) 551

ITWire reports: A flaw in systemd, the init system used on many Linux systems, can be exploited using a malicious DNS query to either crash a system or to run code remotely. The vulnerability resides in the daemon systemd-resolved and can be triggered using a TCP payload, according to Ubuntu developer Chris Coulson. This component can be tricked into allocating less memory than needed for a look-up. When the reply is bigger it overflows the buffer allowing an attacker to overwrite memory. This would result in the process either crashing or it could allow for code execution remotely. "A malicious DNS server can exploit this by responding with a specially crafted TCP payload to trick systemd-resolved in to allocating a buffer that's too small, and subsequently write arbitrary data beyond the end of it," is how Coulson put it.
Affected Linux vendors have pushed out patches -- but the bug has apparently been present in systemd code since June of 2015. And long-time Slashdot reader walterbyrd also reports a recently-discovered bug where systemd unit files that contain illegal usernames get defaulted to root.

Development on the Linux 4.12 kernel kicked off in mid-May with the first release candidate, and now, seven weeks later we can finally get our hands on the final release... A lot of great improvements, new hardware support, and new security features were added during all this time, which makes it one of the biggest releases, after Linux 4.9...

Prominent features of the Linux 4.12 kernel include initial support for AMD Radeon RX Vega graphics cards, intial Nvidia GeForce GTX 1000 "Pascal" accelerated support, implementation of Budget Fair Queueing (BFQ) and storage-I/O schedulers, more MD RAID enhancements, support for Raspberry Pi's Broadcom BCM2835 thermal driver, a lot of F2FS optimizations, as well as ioctl for the GETFSMAP space mapping ioctl for both XFS and EXT4 filesystems.

Linus said in announcing the release that "I think only 4.9 ends up having had more commits," also noting that 4.9 was a Long Term Support kernel, whereas "4.12 is just plain big."

"There's also nothing particularly odd going on in the tree - it's all just normal development, just more of it than usual."

Ubuntu Disputes 'Ads In MOTD' Claims (twitter.com) 110

Thursday Lproven (Slashdot reader #6030) wrote: It appears that Ubuntu is using a feature it has added -- intended to insert headlines of breaking tech news (security alerts and so on) into the Message of the Day displayed at login to the console -- to display advertising and promotional messages.
The message in question linked to a Hacker Noon article titled "How HBO's Silicon Valley built 'Not Hotdog' with mobile TensorFlow, Keras & React Native." Later that day Dustin Kirkland, a Ubuntu Product Manager for the feature's design (and the Core Developer for its implementation) suggested the message had been mistaken for an ad, describing it on Hacker News as a "fun fact... an interesting tidbit of potpourri from the world of Ubuntu," and later saying it was intended like Google's doodles. "Last week's message actually announced an Ubuntu conference in Latin America. The week before, we linked to an article asking for feedback on Kubuntu. Before that, we announced the availability of Extended Security Maintenance updates for 12.04. And so on." He later confirmed Canonical received no money for the message, and also pointed out that the messages all come from an open source repository, and "You're welcome to propose your own messages for merging, if you have a well formatted, informative message for Ubuntu users."

System76 Unveils Its Own Ubuntu-Based Linux Distribution Called 'Pop!_OS' (betanews.com) 117

BrianFagioli writes: Not content with simply following Canonical and embracing vanilla GNOME, System76 has decided to take its future into its own hands. Today, the company releases the first alpha of an all-new Linux-based operating system called "Pop!_OS," which will eventually be the only OS pre-loaded on its computers. While it will still be based on Ubuntu and GNOME, System76 is tweaking it with its own style and included drivers. In other words, the company is better controlling the user experience, and that is smart.

"The Pop!_OS community is in its infancy. This is a fantastic time to engage with and help develop the processes and practices that will govern the future development of the operating system and its community. The team is currently opening up planning for the development roadmap, code of conduct, discussion forums, and the processes surrounding code contribution. Progress made on Pop!_OS has established an inviting, modern, and minimalist look and has improved the first-use experience including streamlining installation and user setup. Work on the first release, scheduled for October 19th, centers on appearance, stability, and overall tightness of the user experience followed by adding new features and greater customization ability," says System76.
You can check out the project on GitHub here and download the alpha ISO here. For more information, the company has set up a subreddi.

Linus Explains What Surprises Him After 25 Years Of Linux (linux.com) 181

Linus Torvalds appeared in a new "fireside chat" with VMware Head of Open Source Dirk Hohndel. An anonymous reader writes: Linus explained what still surprises him about Linux development. "Code that I thought was stable continually gets improved. There are things we haven't touched for many years, then someone comes along and improves them or makes bug reports in something I thought no one used. We have new hardware, new features that are developed, but after 25 years, we still have old, very basic things that people care about and still improve... Our processes have not only worked for 25 years, we still have a very strong maintainer group... And as these maintainers get older and fatter, we have new people coming in."

Linus also says he's surprised by the widespread popularity of Git. "I expected it to be limited mostly to the kernel -- as it's tailored to what we do... In certain circles, Git is more well known than Linux." And he also shares advice if you want to get started as an open source developer. "I'm not sure my example is the right thing for people to follow. There are a ton of open source projects and, if you are a beginning programmer, find something you're interested in that you can follow for more than just a few weeks... If you can be part of a community and set up patches, it's not just about the coding, but about the social aspect of open source. You make connections and improve yourself as a programmer."

Linus also says that "I really like what I'm doing. I like waking up and having a job that is technically interesting and challenging without being too stressful so I can do it for long stretches; something where I feel I am making a real difference and doing something meaningful not just for me."

Survey Says: Raspberry Pi Still Rules, But X86 SBCs Have Made Gains (linuxgizmos.com) 82

DeviceGuru writes: Results from LinuxGizmos.com's annual hacker-friendly single board computer survey are in, and not surprisingly, the Raspberry Pi 3 is the most desired maker SBC by a 4-to-1 margin. In other trends: x86 SBCs and Linux/Arduino hybrids have trended upwards. The site's popular hacker SBC survey polled 1,705 survey respondents and asked for their first, second, and third favorite SBCs from a curated list of 98 community oriented, Linux- and Android-capable boards. Spreadsheets comparing all 98 SBCs' specs and listing their survey vote tallies are available in freely downloadable Google Docs.
Other interesting findings:
  • "A Raspberry Pi SBC has won in all four of our annual surveys, but never by such a high margin."
  • The second-highest ranked board -- behind the Raspberry Pi 3 -- was the Raspberry Pi Zero W.
  • "The Raspberry Pi's success came despite the fact that it offers some of the weakest open source hardware support in terms of open specifications. This, however, matches up with our survey responses about buying criteria, which ranks open source software support and community over open hardware support."
  • "Despite the accelerating Raspberry Pi juggernaut, there's still plenty of experimentation going on with new board models, and to a lesser extent, new board projects."

'Stack Clash' Linux Flaw Enables Root Access. Patch Now (threatpost.com) 126

msm1267 writes: Linux, BSD, Solaris and other open source systems are vulnerable to a local privilege escalation vulnerability known as Stack Clash that allows an attacker to execute code at root. Major Linux and open source distributors made patches available Monday, and systems running Linux, OpenBSD, NetBSD, FreeBSD or Solaris on i386 or amd64 hardware should be updated soon.

The risk presented by this flaw, CVE-2017-1000364, becomes elevated especially if attackers are already present on a vulnerable system. They would now be able to chain this vulnerability with other critical issues, including the recently addressed Sudo vulnerability, and then run arbitrary code with the highest privileges, said researchers at Qualys who discovered the vulnerability.

Phoronix Announces '2017 Linux Laptop Survey' (google.com) 66

Phoronix is hosting a 2017 Linux Laptop Survey. From their site: While Linux laptop compatibility is much better than where it was years ago, it's still not too uncommon to run into display/hybrid issues, shorter battery life under Linux than Windows or macOS, touchpad problems, and other occasional compatibility/performance shortcomings. So we've established this Linux Laptop Survey in conjunction with Linux stakeholders to hopefully gather more feedback that will be useful to many different parties...
The survey will be online until July 6th, after which the results will be publicly available, and will determine the most popular brands, distros, screen sizes, and GPUs, as well as common pain points and popular price points. And one particularly interestng question asks respondents what they'd like to see in a "dream Linux laptop."

Linus Torvalds Says Linux Still Surprises and Motivates Him (linux.com) 78

Linus Torvalds: What I find interesting is code that I thought was stable continually gets improved. There are things we haven't touched for many years, then someone comes along and improves them or makes bug reports in something I thought no one used. We have new hardware, new features that are developed, but after 25 years, we still have old, very basic things that people care about and still improve. I really like what I'm doing. I like waking up and having a job that is technically interesting and challenging without being too stressful so I can do it for long stretches; something where I feel I am making a real difference and doing something meaningful not just for me. I occasionally have taken breaks from my job. The 2-3 weeks I worked on Git to get that started for example. But every time I take a longer break, I get bored. When I go diving for a week, I look forward to getting back. I never had the feeling that I need to take a longer break.

Ask Slashdot: Best Way To Isolate a Network And Allow Data Transfer? 237

Futurepower(R) writes: What is the best way to isolate a network from the internet and prevent intrusion of malware, while allowing carefully examined data transfer from internet-facing computers? An example of complete network isolation could be that each user would have two computers with a KVM switch and a monitor and keyboard, or two monitors and two keyboards. An internet-facing computer could run a very secure version of Linux. Any data to be transferred to that user's computer on the network would perhaps go through several Raspberry Pi computers running Linux; the computers could each use a different method of checking for malware. Windows computers on the isolated network could be updated using Autopatcher, so that there would never be a direct connection with the internet. Why not use virtualization? Virtualization does not provide enough separation; there is the possibility of vulnerabilities. Do you have any ideas about improving the example above?

Munich's Green Party is citing the WannaCry virus as a valid reason not to switch to Windows. "As with many of the biggest attacks, the computers that were mainly hit were running the Windows operating system," the Green Party said in a statement.

Linux Malware Infects Raspberry Pi Devices And Makes Them Mine Cryptocurrency (hothardware.com) 84

An anonymous reader quotes Hot Hardware: If you're a Raspberry Pi user who's never changed the default password of the "pi" user, then heed this warning: change it. A brand new piece of malware has hit the web, called "Linux.MulDrop.14", and it preys on those who haven't secured their devices properly... After scanning for RPis with an open (and default) SSH port, the "pi" user is logged into (if the password is left default), and the password is subsequently changed. After that, the malware installs ZMap and sshpass software, and then it configures itself. The ultimate goal of Linux.MulDrop.14 is to make digital money for someone else, namely the author of the malware, using your Raspberry Pi.

Docker's LinuxKit Launches Kernel Security Efforts, Including Next-Generation VPN (eweek.com) 44

darthcamaro writes: Back in April, when Docker announced its LinuxKit effort, the primary focus appeared to just be [tools for] building a container-optimized Linux distribution. As it turns out, security is also a core focus -- with LinuxKit now incubating multiple efforts to help boost Linux kernel security. Among those efforts is the Wireguard next generation VPN that could one day replace IPsec. "Wireguard is a new VPN for Linux using the cryptography that is behind some of the really good secure messaging apps like Signal," said Nathan McCauley, Director of Security at Docker Inc.
According to the article, Docker also has several full-time employees looking at ways to reduce the risk of memory corruption in the kernel, and is also developing a new Linux Security Module with more flexible access control policies for processes.

Ubuntu Works With GNOME To Improve HiDPI Support On Linux Desktop (omgubuntu.co.uk) 85

An anonymous reader shares an article: Canonical is playing host to a 'fractional scaling hackfest' in its Taipei offices this week. Both GNOME developers and Ubuntu developers are in attendance, ready to wrestle with the aim: improve GNOME HiDPI support. Ubuntu's Unity desktop (I'm told, anyhow) plays fairly nice with high DPI monitors because the shell supports fractional scaling (though most apps, I believe, do not). Furthermore, users can tweak some high DPI settings to better suit their display(s). GNOME Shell also supports HiDPI monitors, but has, until now, been a little less flexible about it. "Currently, we only allow to scale windows by integral factors (typically 2). This proves somewhat limiting as there are many systems that are just in between the dpi ranges that are good for scale factor 2, or unscaled," the hackfest page explains.

OpenELEC 8.0.4 Kodi-Focused Linux Distro Now Available (openelec.tv) 43

BrianFagioli writes: Unfortunately, Kodi is not its own operating system, meaning it has to be run on top of an OS. Sure, you could use Windows 10, but that is overkill if you only want to run Kodi. Instead, a lightweight Linux distribution that only serves to run the media center is preferable. One of the most popular such distros is OpenELEC. It can run on traditional PC hardware, but also Raspberry Pi, and, my favorite — WeTek boxes. Today, version 8.0.4 achieves stable release. It is a fairly ho-hum update, focusing mostly on fixes and stability.

The team shares the following changes in the release.

- fix crash in WeTek DVB driver on WeTek Play (1st gen).
- enable Kernel NEON mode for RPi2 builds.
- enable some more SOC sound drivers for RPi/RPi2 builds.
- enable Regulator support on all builds.
- enable Extcon support on all builds.
- fix loading for some I2C sound modules on RPI/RPi2 builds.
- fix loading splash screen on systems with Nvidia GPUs.
- fix speed problems on Nvidia ION systems.
- fix problems loading dvbhdhomerun addons.
- fix using user created sleep scripts.
- build PNG support with SSE support for x86_64 builds.
- update to linux-4.9.30, mesa-17.0.7, alsa-lib-1.1.4.1, alsa-utils-1.1.4, kodi-17,3, mariadb-10.1.23, samba-4.6.4.

Technology Is Making the World More Unequal; Only Technology Can Fix This (theguardian.com) 145

mspohr shares an excerpt from an article written by Cory Doctorow via The Guardian: The inequality of badly-run or corrupt states is boosted by the power of technology -- but it's also easier than ever to destabilize these states, thanks to technology. The question is: which future will prevail?" [The article discusses two sides to the issue:] Here's the bad news: technology -- specifically, surveillance technology -- makes it easier to police disaffected populations, and that gives badly run, corrupt states enough stability to get themselves into real trouble. Here's the good news: technology -- specifically, networked technology -- makes it easier for opposition movements to form and mobilize, even under conditions of surveillance, and to topple badly run, corrupt states. Long before the internet radically transformed the way we organize ourselves, theorists were predicting we'd use computers to achieve ambitious goals without traditional hierarchies -- but it was a rare pundit who predicted that the first really successful example of this would be an operating system (GNU/Linux), and then an encyclopedia (Wikipedia). [Cory also has a new novel, Walkaway , which explores these ideas further.] The future will see a monotonic increase in the ambitions that loose-knit groups can achieve. My new novel, Walkaway, tries to signpost a territory in our future in which the catastrophes of the super-rich are transformed into something like triumphs by bohemian, anti-authoritarian "walkaways" who build housing and space programs the way we make encyclopedias today: substituting (sometimes acrimonious) discussion and (sometimes vulnerable) networks for submission to the authority of the ruling elites.

Wormable Code-Execution Bug Lurked In Samba For 7 Years (arstechnica.com) 83

Long-time Slashdot reader williamyf was the first to share news of "a wormable bug [that] has remained undetected for seven years in Samba verions 3.5.0 onwards." Ars Technica reports: Researchers with security firm Rapid7...said they detected 110,000 devices exposed on the internet that appeared to run vulnerable versions of Samba. 92,500 of them appeared to run unsupported versions of Samba for which no patch was available... Those who are unable to patch immediately can work around the vulnerability by adding the line nt pipe support = no to their Samba configuration file and restart the network's SMB daemon. The change will prevent clients from fully accessing some network computers and may disable some expected functions for connected Windows machines.
The U.S. Department of Homeland Security's CERT group issued an anouncement urging sys-admins to update their systems, though SC Magazine cites a security researcher arguing this attack surface is much smaller than that of the Wannacry ransomware, partly because Samba is just "not as common as Windows architectures." But the original submission also points out that while the patch came in fast, "the 'Many eyes' took seven years to 'make the bug shallow'."
