We are shipping the latest GNOME 3.30, Firefox 63, LibreOffice 6.1.2, and many others. Ubuntu Server 18.10 includes the Rocky release of OpenStack including the clustering enabled LXD 3.0, new network configuration via, and iteration on the next-generation fast server installer.

The PostgreSQL 11 release is out. "PostgreSQL 11 provides users with improvements to overall performance of the database system, with specific enhancements associated with very large databases and high computational workloads. Further, PostgreSQL 11 makes significant improvements to the table partitioning system, adds support for stored procedures capable of transaction management, improves query parallelism and adds parallelized data definition capabilities, and introduces just-in-time (JIT) compilation for accelerating the execution of expressions in queries." See this article for a detailed overview of what is in this release.

[$] Making the GPL more scary

9 hours 1 min ago
For some years now, one has not had to look far to find articles proclaiming the demise of the GNU General Public License. That license, we are told, is too frightening for many businesses, which prefer to use software under the far weaker permissive class of license. But there is a business model that is based on the allegedly scary nature of the GPL, and there are those who would like to make it more lucrative; the only problem is that the GPL isn't quite scary enough yet.

[$] A new direction for i965

Wednesday 17th of October 2018 10:30:08 PM

Graphical applications are always pushing the limits of what the hardware can do and recent developments in the graphics world have caused Intel to rethink its 3D graphics driver. In particular, the lower CPU overhead that the Vulkan driver on Intel hardware can provide is becoming more attractive for OpenGL as well. At the 2018 X.Org Developers Conference Kenneth Graunke talked about an experimental re-architecting of the i965 driver using Gallium3D—a development that came as something of a surprise to many, including him.

[$] Secure key handling using the TPM

Wednesday 17th of October 2018 04:36:57 PM

Trusted Computing has not had the best reputation over the years — Richard Stallman dubbing it "Treacherous Computing" probably hasn't helped — though those fears of taking away users' control of their computers have not proven to be founded, at least yet. But the Trusted Platform Module, or TPM, inside your computer can do more than just potentially enable lockdown. In our second report from Kernel Recipes 2018, we look at a talk from James Bottomley about how the TPM works, how to talk to it, and how he's using it to improve his key handling.

[$] A farewell to email

Tuesday 16th of October 2018 10:29:04 PM
The free-software community was built on email, a distributed technology that allows people worldwide to communicate regardless of their particular software environment. While email remains at the core of many projects' workflow, others are increasingly trying to move away from it. A couple of recent examples show what is driving this move and where it may be headed.

Bro becomes Zeek

Tuesday 16th of October 2018 04:43:32 PM
The Bro network security monitoring project has announced a name change to "Zeek". "On the Leadership Team of the Bro Project, we heard clear concerns from the Bro community that the name 'Bro' has taken on strongly negative connotations, such as 'Bro culture'. These send a sharp, anti-inclusive - and wholly unintended and undesirable - message to those who might use Bro. The problems were significant enough that during BroCon community sessions, several people have mentioned substantial difficulties in getting their upper management to even consider using open-source software with such a seemingly ill-chosen, off-putting name."

SFLC: Automotive Software Governance and Copyleft

Tuesday 16th of October 2018 03:28:35 PM
The Software Freedom Law Center has announced the availability of a whitepaper [PDF] about automotive software and copyleft, written by Mark Shuttleworth and Eben Moglen. At its core, it's an advertisement for Ubuntu and Snap, but it does look at some of the issues involved.

The fine grain of interface access rights provided by the snapd governance agent can thus provide further isolation and security when it is running user-modified code, guaranteed under the snap packaging paradigm to cause no other program code to be modified, to break, or to perform differently because of the presence of the user-modified program. Such a structure of modification permission can be operated by the OEM consistent with the requirements of GPLv3. The OEM can publish an authenticated record of the installation permission issued, indexed by the Vehicle Identification Number—without publishing the car owner’s personal information—so that public and private parties can be assured that no surreptitious modification of vehicle software occurs.

[$] Fighting Spectre with cache flushes

Monday 15th of October 2018 11:23:44 PM
One of the more difficult aspects of the Spectre hardware vulnerability is finding all of the locations in the code that might be exploitable. There are many locations that look vulnerable that aren't, and others that are exploitable without being obvious. It has long been clear that finding all of the exploitable spots is a long-term task, and keeping new ones from being introduced will not be easy. But there may be a simple technique that can block a large subset of the possible exploits with a minimal cost.

[$] I/O scheduling for single-queue devices

Friday 12th of October 2018 05:03:33 PM
Block I/O performance can be one of the determining factors for the performance of a system as a whole, especially on systems with slower drives. The need to optimize I/O patterns has led to the development of a long series of I/O schedulers over the years; one of the most recent of those is BFQ, which was merged during the 4.12 development cycle. BFQ incorporates an impressive set of heuristics designed to improve interactive performance, but it has, thus far, seen relatively little uptake in deployed systems. An attempt to make BFQ the default I/O scheduler for some types of storage devices has raised some interesting questions, though, on how such decisions should be made.
