Spencer: The Community Team

k, 2014-07-22 21:44
Rick Spencer introduces Ubuntu's community team. "First, we created the role Community Team Manager. Notice the important inclusion of the word “Team”. This person’s job is not to “manage the community”, but rather to organize and lead the rest of the community team members. This includes things like project planning, HR responsibilities, strategic planning and everything else entailed in being a good line manager. After a rather competitive interview process, with some strong candidates, one person clearly rose to the top as the best candidate. So, I would like formally introduce David Planella as the Community Team Manager!" Michael Hall, Daniel Holbach, and Nicholas Skaggs are the other members of the team.

Docker security with SELinux (Opensource.com)

k, 2014-07-22 20:51
Dan Walsh looks at container security, on Opensource.com. "I hear and read about a lot of people assuming that Docker containers actually sandbox applications—meaning they can run random applications on their system as root with Docker. They believe Docker containers will actually protect their host system [...] Stop assuming that Docker and the Linux kernel protect you from malware."

The EFF's open wireless router project

h, 2014-07-21 14:04
The Electronic Frontier Foundation has announced a project to create a new distribution for wireless home routers. It is based on CeroWrt and is meant to make it easy and safe to run an open wireless network, include all of the latest bufferbloat fixes, and "advance the state of the art in consumer Wi-Fi router security and begin turning back the growing tide of attacks against them." The work is in an early state and only runs on Netgear WNDR3800 routers for now; testers and contributors are eagerly sought.

Kernel prepatch 3.16-rc6

h, 2014-07-21 13:55
The 3.16-rc6 release is out, and Linus is starting to think that things are still too active. "Anyway, rc6 still isn't all *that* big, so I'm not exactly worried, but I am getting to the point where I'm going to start calling people names and shouting at you if you send me stuff that isn't appropriate for the late rc releases. Which is not to say that people did: while rc6 is bigger than I wished for, I don't think there's too much obviously frivolous in there. But I'll be keeping an eye out, and I'll be starting to get grumpy (or grumpiER) if I notice that people aren't being serious about trying to calm things down."

Changes on the openSUSE board

p, 2014-07-18 16:15
OpenSUSE board chair Vincent Untz has announced that he will be stepping down from the position to free time for other priorities. "I'm stepping down with regrets because these two years as chairman have been totally awesome, and I would love to keep contributing to the project that way. But I know I won't have enough time to dedicate to being a chairman in the months to come, and I'm a strong believer that board members (including the chairman) should be active in their role. Having motivation is extremely important, of course, but free time is simply essential." SUSE has chosen Richard Brown as Vincent's successor.

Faults in Linux 2.6

cs, 2014-07-17 22:36
Six researchers (including Julia Lawall of the Coccinelle project) have just released a paper [PDF] (abstract) that looks at the faults in the 2.6 kernel. "In August 2011, Linux entered its third decade. Ten years before, Chou et al. published a study of faults found by applying a static analyzer to Linux versions 1.0 through 2.4.1. A major result of their work was that the drivers directory contained up to 7 times more of certain kinds of faults than other directories. This result inspired numerous efforts on improving the reliability of driver code. Today, Linux is used in a wider range of environments, provides a wider range of services, and has adopted a new development and release model. What has been the impact of these changes on code quality? To answer this question, we have transported Chou et al.'s experiments to all versions of Linux 2.6; released between 2003 and 2011. We find that Linux has more than doubled in size during this period, but the number of faults per line of code has been decreasing. Moreover, the fault rate of drivers is now below that of other directories, such as arch. These results can guide further development and research efforts for the decade to come. To allow updating these results as Linux evolves, we define our experimental protocol and make our checkers available." (Thanks to Asger Alstrup Palm.)

The state of accessibility in Linux and open source software (Opensource.com)

cs, 2014-07-17 22:18
Over at Opensource.com, Rikki Endsley interviews Spencer Hunley, who will be giving a talk on accessibility at LinuxCon NA in August. Hunley also spoke at last year's LinuxCon NA and, shortly after that, helped form the Universal Tux Google+ community to work on accessibility in Linux. "Built-in, easy to use and understand accessibility support is hard to find in many distributions. Can you tell me the key combination to activate that support in Ubuntu? How about any other distro? The fact is that although it's there, it may not be easy to locate and/or use. When addressing this, focusing on independence is vital. No one wants to have to call upon someone else to help them install a new OS, or to utilize an application. This is especially true for people with disabilities; the learning curve can be nearly impossible, which leaves little in the way of choice in the FOSS world, depending on your abilities."

2014 Linux Security Summit schedule published

sze, 2014-07-16 01:56
James Morris has a blog post announcing that the schedule for this year's Linux Security Summit (LSS) is now available. It starts with a keynote from James Bottomley of Parallels, then there are seven refereed talks, as well as other sessions: "Discussion session topics include Trusted Kernel Lock-down Patch Series, led by Kees Cook; and EXT4 Encryption, led by Michael Halcrow & Ted Ts’o. There’ll be kernel security subsystem updates from the SELinux, AppArmor, Smack, and Integrity maintainers. The break-out sessions are open format and a good opportunity to collaborate face-to-face on outstanding or emerging issues." LSS will be held August 18-19 in Chicago, overlapping the first two days of the Kernel Summit and it is followed by LinuxCon North America; all are being held in the same location.

OpenSSL fork LibreSSL is declared “unsafe for Linux” (Ars Technica)

sze, 2014-07-16 00:25
Ars Technica reports that a security researcher has found what he calls a "catastrophic failure" in the Linux version of LibreSSL. "The failure results in cases where the same 16-bit PID is used to designate two or more processes. Linux ensures that a process can never have the same ID as the child process it spawned, but it remains possible for a process to have the same PID as its grandparent process. The condition appears to be an edge case, but it's one that may be possible if the Linux fork_rand program forks enough times to produce identical PIDs. OpenSSL, the open-source program LibreSSL aims to replace, has ways to recover from such cases. LibreSSL does not, at least not on Linux."

Update: This issue has been fixed in LibreSSL 2.0.2.

KDE Plasma 5.0

k, 2014-07-15 18:12
KDE has announced the release of Plasma 5.0. "Plasma 5.0 introduces a new major version of KDE's workspace offering. The new Breeze artwork concept introduces cleaner visuals and improved readability. Central work-flows have been streamlined, while well-known overarching interaction patterns are left intact. Plasma 5.0 improves support for high-DPI displays and ships a converged shell, able to switch between user experiences for different target devices. Changes under the hood include the migration to a new, fully hardware-accelerated graphics stack centered around an OpenGL(ES) scenegraph. Plasma is built using Qt 5 and Frameworks 5."
