The Debian Project recently learned that community member Peter Miller died last July. "Peter was a relative newcomer to the Debian project, but his contributions to Free and Open Source Software goes back the the late 1980s. Peter was significant contributor to GNU gettext as well as being the main upstream author and maintainer of other projects that ship as part of Debian, including, but not limited to srecord, aegis and cook. Peter was also the author of the paper "Recursive Make Considered Harmful"."
Ubuntu 14.10 "Utopic Unicorn" is due to be released this week. That marks 10 years of Ubuntu releases, beginning with Ubuntu 4.10 "Warty Warthog". In this article Mark Shuttleworth announces the name of what will the 15.04 release. "This verbose tract is a venial vanity, a chance to vector verbal vibes, a map of verdant hills to be climbed in months ahead. Amongst those peaks I expect we’ll find new ways to bring secure, free and fabulous opportunities for both developers and users. This is a time when every electronic thing can be an Internet thing, and that’s a chance for us to bring our platform, with its security and its long term support, to a vast and important field. In a world where almost any device can be smart, and also subverted, our shared efforts to make trusted and trustworthy systems might find fertile ground. So our goal this next cycle is to show the way past a simple Internet of things, to a world of Internet things-you-can-trust."
The Free Software Foundation (FSF) and the GNU Project have announced the opening of nominations for the 17th annual Free Software Awards. The Free Software Awards include the Award for the Advancement of Free Software and the Award for Projects of Social Benefit. "In the case of both awards, previous winners are not eligible for nomination, but renomination of other previous nominees is encouraged. Only individuals are eligible for nomination for the Advancement of Free Software Award (not projects), and only projects can be nominated for the Social Benefit Award (not individuals). For a list of previous winners, please visit https://www.fsf.org/awards."
Debian has updated iceweasel (multiple vulnerabilities).
Fedora has updated glibc (F19: multiple vulnerabilities), gnome-shell (F20: lock screen bypass), kernel (F19: multiple vulnerabilities), libxml2 (F20: denial of service), openssl (F20; F19: multiple vulnerabilities), openstack-glance (F20: denial of service), and torque (F20; F19: authentication bypass).
Oracle has updated libxml2 (OL6: denial of service).
In a relatively predictable move, Linus has released 3.18-rc1 and closed the 3.18 merge window sooner than expected. He has, however, said that he will be more than usually open to post-rc1 pull requests from people who "grovel a bit." "There is also at least one pull request that I am hoping to get asap and planning on still pulling, ie I'm very much still hoping to get overlayfs finally merged." In the end, 9,711 non-merge changesets found their way into the mainline repository during this merge window.
Linux Voice has an interview with Canonical's Thomas Voß, the technical architect of the Mir display server. The interview deals largely with background topics, such as the Mir team's decision to standardize on an API rather than define a protocol, and the various languages to support. "Obviously there are disadvantages to having only one graphics language, but the benefits outweigh the disadvantages. And I think that’s a common theme in the industry. Android made the same decision to go that way. Even Wayland to a certain degree has been doing that. They have to support EGL and GL, simply because it’s very convenient for app developers and toolkit developers – an open graphics language. That was the part that inspired us, and we wanted to have this one graphics language and support it well."
Debian has updated openssl (multiple vulnerabilities).
Fedora has updated firefox (F20: multiple vulnerabilities), java-1.7.0-openjdk (F20: multiple vulnerabilities), java-1.8.0-openjdk (F20: multiple vulnerabilities), kernel (F20: multiple vulnerabilities), php-ZendFramework (F19; F20: multiple vulnerabilities), and thunderbird (F20: multiple vulnerabilities).
Oracle has updated cups (O6: multiple vulnerabilities), file (O6: multiple vulnerabilities), firefox (O5; O6: multiple vulnerabilities), glibc (O6: multiple vulnerabilities), java-1.6.0-openjdk (O6: multiple vulnerabilities), java-1.7.0-openjdk (O6: multiple vulnerabilities), krb5 (O6: multiple vulnerabilities), libxml2 (O7: denial of service), openssh (O6: multiple vulnerabilities), openssl (O5; O6; O7: multiple vulnerabilities), thunderbird (O6: multiple vulnerabilities), and trousers (O6: denial of service).
Red Hat has updated java-1.6.0-sun (multiple vulnerabilities), java-1.7.0-oracle (multiple vulnerabilities), libxml2 (RHEL6,7: denial of service), openssl (RHEL5: protocol downgrade), openssl (RHEL6,7: multiple vulnerabilities), and rsyslog7 (RHEL6: denial of service).
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.
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."
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."
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."
CentOS has updated thunderbird (C5: multiple vulnerabilities).
Slackware has updated openssl (multiple vulnerabilities).
Ubuntu has updated mysql-5.5 (12.04, 14.04: multiple vulnerabilities).
The LWN.net Weekly Edition for October 16, 2014 is available.
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.
Greg Kroah-Hartman has released four kernel updates: 3.17.1, 3.16.6, 3.14.22, and 3.10.58. All contain the usual set of important fixes.
Debian has updated wireshark (yet another pile of dissector flaws).
Oracle has updated java-1.6.0-openjdk (OL7: multiple vulnerabilities).
Red Hat has updated firefox (RHEL5,6,7: multiple vulnerabilities), java-1.6.0-openjdk (RHEL5,6,7: multiple vulnerabilities), java-1.7.0-openjdk (RHEL6,7; RHEL5: multiple vulnerabilities), and java-1.8.0-openjdk (RHEL6: multiple vulnerabilities).
SUSE has updated rsyslog (SLES11 SP3: two vulnerabilities).
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.
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."
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."
