Kernel prepatch 4.9-rc6

Sunday 20th of November 2016 10:29:12 PM
Linus has released the 4.9-rc6 kernel prepatch for testing. "We're getting further in the rc series, and while things have stayed pretty calm, I'm not sure if we're quite there yet. There's a few outstanding issues that just shouldn't be issues at rc6 time, so we'll just have to see. This may be one of those releases that have an rc8, which considering the size of 4.9 is perhaps not that unusual."

LinuxCon + CloudOpen + ContainerCon Become The Linux Foundation Open Source Summit for 2017

Thursday 17th of November 2016 08:25:50 PM
The Linux Foundation has announced that it is consolidating three conferences under one name going forward. LinuxCon, CloudOpen, and ContainerCon join together under the "Linux Foundation Open Source Summit" name. For 2017, that encompasses three events: OSS Japan in Tokyo May 31-June 2, OSS North America in Los Angeles September 11-13, and OSS Europe in Prague October 23-25. "The Linux Foundation Open Source Summit in North America and Europe will also contain a brand new event, Community Leadership Conference. Attendees will have access to sessions across all events in a single venue, enabling them to collaborate and share information across a wide range of open source topics and areas of technology. They can take advantage of not only unparalleled educational opportunities, but also an expo hall, networking activities, hackathons, additional co-located events and The Linux Foundation’s diversity initiatives, including free childcare, nursing rooms, non-binary restrooms and a diversity luncheon."

Mission Improbable: Hardening Android for Security And Privacy (Tor blog)

Thursday 17th of November 2016 08:02:26 PM
The Tor blog has a post about the refresh of its Tor-enabled Android phone prototype, which is now in a workable state though it still has some rough edges. There is also a worrisome trend that the post highlights: "It is unfortunate that Google seems to see locking down Android as the only solution to the fragmentation and resulting insecurity of the Android platform. We believe that more transparent development and release processes, along with deals for longer device firmware support from SoC vendors, would go a long way to ensuring that it is easier for good OEM players to stay up to date. Simply moving more components to Google Play, even though it will keep those components up to date, does not solve the systemic problem that there are still no OEM incentives to update the base system. Users of old AOSP base systems will always be vulnerable to library, daemon, and operating system issues. Simply giving them slightly more up to date apps is a bandaid that both reduces freedom and does not solve the root security problems. Moreover, as more components and apps are moved to closed source versions, Google is reducing its ability to resist the demand that backdoors be introduced. It is much harder to backdoor an open source component (especially with reproducible builds and binary transparency) than a closed source one."

Farewell to Rob Collins

Wednesday 16th of November 2016 05:36:31 PM
The EuroPython Society shares the sad news that Rob Collins has passed away. "Many of you may know Rob from the sponsored massage sessions he regularly ran at EuroPython in recent years and which he continued to develop, taking them from a single man setup (single threaded process) to a group of people setup by giving workshops (multiprocessing) and later on by passing on his skills to more leaders (removing the GIL) to spread wellness and kindness throughout our conference series."

The "cryptsetup initrd root shell" vulnerability

Tuesday 15th of November 2016 03:58:04 PM
Hector Marco and Ismael Ripoll report a discouraging vulnerability in many encrypted disk setups: simply running up too many password failures will eventually result in a root shell. "This vulnerability allows to obtain a root initramfs shell on affected systems. The vulnerability is very reliable because it doesn't depend on specific systems or configurations. Attackers can copy, modify or destroy the hard disc as well as set up the network to exfiltrate data. This vulnerability is specially serious in environments like libraries, ATMs, airport machines, labs, etc, where the whole boot process is protect (password in BIOS and GRUB) and we only have a keyboard or/and a mouse."

KDE neon users may want to reinstall

Monday 14th of November 2016 10:14:29 PM
The KDE Project has a little problem to report for users of the KDE neon distribution: "The package archive used by KDE neon was incorrectly configured allowing anyone to upload packages to it. There is no reason to think that anyone actually did so but as a precaution we have emptied the archives and removed ISOs built before this date." Once the process of rebuilding the archive is complete, users are recommended to upgrade to the new versions, or, better, simply reinstall.

[$] Topics in live kernel patching

Monday 14th of November 2016 08:42:31 PM
Getting live-patching capabilities into the mainline kernel has been a multi-year process. Basic patching support was merged for the 4.0 release, but further work has been stalled over disagreements on how the consistency model — the code ensuring that a patch is safe to apply to a running kernel — should work. The addition of kernel stack validation has addressed the biggest of the objections, so, arguably, it is time to move forward. At the 2016 Linux Plumbers Conference, developers working on live patching got together to discuss current challenges and future directions.

Kernel prepatch 4.9-rc5

Sunday 13th of November 2016 07:27:53 PM
The 4.9-rc5 kernel prepatch is out. Linus says: "Things have definitely gotten smaller, so a normal release schedule (with rc7 being the last one) is still looking possible despite the large size of 4.9. But let's see how things work out over the next couple of weeks. In the meantime, there's a lot of normal fixes in here, and we just need more testing."

The Libreboot C201 from Minifree is really really really ridiculously open source

Open source laptops – ones not running any commercial software whatsoever – have been the holy grail for free software fans for years. Now, with the introduction of libreboot, a truly open source boot firmware, the dream is close to fruition. The $730 laptop is a bog standard piece of hardware but it contains only open source software. The OS, Debian, is completely open source and to avoid closed software the company has added an Atheros Wi-Fi dongle with open source drivers rather than use the built-in Wi-Fi chip. Read more
