The Debian init system general resolution returns

p, 2014-10-17 06:34
Ian Jackson has resurrected the general resolution prohibiting Debian packages from depending on a single init system. This resolution failed to obtain enough seconds to proceed to a vote back in March, but this time more seconds have appeared and a vote will take place after the two-week discussion period. The initial discussion suggests that there is some support for the idea, but that not everybody appreciates seeing this resolution just before the jessie release is supposed to go into a freeze.

Docker 1.3 released

cs, 2014-10-16 22:47
The 1.3 release of the Docker container system is available. "First up, in this release, the Docker Engine will now automatically verify the provenance and integrity of all Official Repos using digital signatures. Official Repos are Docker images curated and optimized by the Docker community to be the best building blocks for assembling distributed applications. A valid signature provides an added level of trust by indicating that the Official Repo image has not been tampered with."

GCC Undefined Behavior Sanitizer – ubsan (RH Developer Blog)

cs, 2014-10-16 22:45
The Red Hat Developer Blog has an article about the undefined behavior sanitizer that was a part of the GCC 4.9 release. "One of the most important [checks] is the signed integer overflow checking. The practice shows that this undefined behavior is very common in real programs. Ubsan is able to check that the result of addition, subtraction, multiplication and negation does not overflow in signed arithmetic."

Tor Browser 4.0 released

cs, 2014-10-16 22:41
Version 4.0 of the Tor Browser is now available. "The primary user-facing change since the 3.6 series is the transition to Firefox 31-ESR. More importantly for censored users who were using 3.6, the 4.0 series also features the addition of three versions of the meek pluggable transport. In fact, we believe that both meek-amazon and meek-azure will work in China today, without the need to obtain bridge addresses."

[$] A damp discussion of network queuing

sze, 2014-10-15 22:01
Very few presenters at technical conferences come equipped with gallons of water and a small inflatable swimming pool to contain it. But that is just how Stephen Hemminger showed up at the 2014 Linux Plumbers Conference. Stephen was there to talk about the current state of the fight against bufferbloat; while there was some good news to share, the sad fact is that, in a number of areas, we are still all wet.

The POODLE vulnerability

sze, 2014-10-15 16:05
Google has disclosed a new SSL vulnerability that goes by the name POODLE. In essence: a man-in-the-middle attacker can force a connection to drop back to the obsolete SSL 3.0 protocol, then recover plaintext data. "Disabling SSL 3.0 support, or CBC-mode ciphers with SSL 3.0, is sufficient to mitigate this issue, but presents significant compatibility problems, even today. Therefore our recommended response is to support TLS_FALLBACK_SCSV. This is a mechanism that solves the problems caused by retrying failed connections and thus prevents attackers from inducing browsers to use SSL 3.0. It also prevents downgrades from TLS 1.2 to 1.1 or 1.0 and so may help prevent future attacks." The OpenSSL project has issued an advisory describing its response to a few vulnerabilities, POODLE included.

White paper: the state of KVM

sze, 2014-10-15 11:03
For those with an interest in the KVM hypervisor: the Linux Foundation's Open Virtualization Alliance has published a white paper [PDF] with an overview of KVM and where it is going. "OpenStack is one of the brightest spots for KVM. As cloud deployments gain in adoption, OpenStack is the leading open source option and has tremendous community momentum behind it. KVM is the most popular hypervisor for OpenStack deployments, so as OpenStack succeeds, so will KVM."

What’s new in the graphics stack in Fedora 21? (Fedora Magazine)

sze, 2014-10-15 00:16
Fedora Magazine looks at new features in the Fedora 21 graphics stack. "This article details some of the driver support and feature updates that will be available for the graphics stack in Fedora 21. Note that this post does contain some pretty low level details about new drivers and features in Fedora 21. While most users won’t directly see many of these features in day to day usage, the effects of all these low-level updates make more graphics cards work better on Fedora. Special thanks to Adam Jackson for collating this list of updates for this article."

The Linux Foundation announces Dronecode

h, 2014-10-13 14:32
The Linux Foundation has announced a new project, called Dronecode, that is concerned with free systems to drive autonomous vehicles — drones, in other words. There is a lot of code already in place, it seems. "Today more than 1,200 developers are working on Dronecode projects with more than 150 code commits a day on some projects." Andrew "Tridge" Tridgell is the chair of the project's steering committee.
