Cluetrain at Fifteen (Linux Journal)

sze, 2014-08-27 01:13
Doc Searls looks back over the fifteen years that have passed since he (along with Chris Locke, David Weinberger and Rick Levine) wrote "The Cluetrain Manifesto". "What we had in mind was much fresher to me in the Summer of 2000, when I worked with Jason Schumaker, another Linux Journal editor, on an interview about Cluetrain and its relevance to Linux. What we ended up with was too long for both the magazine and our website at the time, so the project got sidelined and eventually buried in archival directories, where it stayed until this morning, when I found it during a search for something else. Reading it, I realized that I had come across a kind of time capsule."

The poisoned NUL byte, 2014 edition (Project Zero)

k, 2014-08-26 15:15
For those interested in the gory details of a complex exploit, Google's Project Zero page describes the process of getting arbitrary code execution from a single NUL byte written to the heap by glibc in an off-by-one error. "The main point of going to all this effort is to steer industry narrative away from quibbling about whether a given bug might be exploitable or not. In this specific instance, we took a very subtle memory corruption with poor levels of attacker control over the overflow, poor levels of attacker control over the heap state, poor levels of attacker control over important heap content and poor levels of attacker control over program flow. Yet still we were able to produce a decently reliable exploit! And there’s a long history of this over the evolution of exploitation: proclamations of non-exploitability that end up being neither advisable nor correct."

Kernel prepatch 3.17-rc2

k, 2014-08-26 14:28
Linus has released 3.17-rc2 a little later than might have been expected. "So I deviated from my normal Sunday schedule partly because there wasn't much there (I blame the KS and LinuxCon), but partly due to sentimental reasons: Aug 25 is the anniversary of the original Linux announcement ('Hello everybody out there using minix'), so it's just a good day for release announcements."

[$] news: two-factor authentication and more

h, 2014-08-25 18:33
Kernel developers depend heavily on for the hosting of Git repositories and the management of patch flow in general, so it is not surprising that the annual Kernel Summit sets aside a slot to discuss what is happening with this site. In recent years, there has been a lot of change to discuss, mostly relating to the reorganization of management resulting from the compromise of the site in 2011. The 2014 discussion, run by Konstantin Ryabitsev, shows that, in a lot of ways, the pace of change is slowing, but the maintainers are still working to improve their support and make it more secure.

Day: New Human Interface Guidelines for GNOME and GTK+

p, 2014-08-22 23:25

At his blog, Allan Day announces the preliminary availability of a brand-new edition of the GNOME Human Interface Guidelines (HIG). Prepared for the upcoming GNOME 3.14 release, this is the first major overhaul of the GNOME HIG in some time. Day notes: "There is a downside to all the experimentation that has been happening in software design in recent years, of course – it can often be a bewildering space to navigate. This is where the HIG comes in. Its goal is to help developers and designers take advantage of the new abilities at their disposal, without losing their way in the process. This is reflected in the structure of the new HIG: the guidelines don’t enforce a single template on which applications have to be based, but presents a series of patterns and elements which can be drawn upon." He also emphasizes that the new HIG, despite its name, is not a GNOME-only document, but is designed to aid interface design in other GTK+ applications, too.

FSF: GNU hackers discover HACIENDA government surveillance and give us a way to fight back

p, 2014-08-22 00:40

The Free Software Foundation blog has posted an article detailing a newly discovered government surveillance project as well as a new technological countermeasure. The surveillance project is known as HACIENDA, as is reportedly a multi-national effort "to map every server in twenty-seven countries, employing a technique known as port scanning." The countermeasure, developed by Julian Kirsch, Christian Grothoff, Jacob Appelbaum, and Holger Kenn, is called TCP Stealth. According to the TCP Stealth whitepaper, the system "replaces the traditional random TCP SQN number with a token that authenticates the client and (optionally) the first bytes of the TCP payload. Clients and servers can enable TCP Stealth by explicitly setting a socket option or linking against a library that wraps existing network system calls." A Linux implementation of the scheme is available.

[$] GNOME development updates from GUADEC

sze, 2014-08-20 21:39

A project as large as GNOME consists of enough constituent parts that it can be a challenge just to keep up with the latest developments of the various applications, libraries, and infrastructure efforts. GUADEC 2014 in Strasbourg provided a number of opportunities to get up speed on the various moving pieces. Of course, it is impossible to catch everything at a multi-track event, but there were still quite a few updates worth mentioning.

Linux Kernel Git Repositories Add 2-Factor Authentication (

k, 2014-08-19 19:47 takes a look at using 2-factor authentication for commit access to kernel git repositories. "Having the technology available is one thing, but how to incorporate it into the kernel development process -- in a way that doesn't make developers' lives painful and unbearable? When we asked them, it became abundantly clear that nobody wanted to type in 6-digit codes every time they needed to do a git remote operation. Where do you draw the line between security and usability in this case? We looked at the options available in gitolite, the git repository management solution used at, and found a way that allowed us to trigger additional checks only when someone performed a write operation, such as "git push." Since we already knew the username and the remote IP address of the developer attempting to perform a write operation, we put together a verification tool that allowed developers to temporarily whitelist their IP addresses using their 2-factor authentication token."
