Greg Kroah-Hartman has announced the release of a new batch of stable kernels: 3.13.4, 3.12.12, 3.10.31, and 3.4.81. Each contains fixes throughout the tree and users of those series should upgrade.
On his blog, Martin Peres has a lengthy discourse on security in Wayland, which is targeted at replacing X some day. He looks at security properties, the current state of security in Wayland, and has recommendations for Wayland compositor authors on handling privileged clients. "While I think the user-intent method has a higher security than static privilege assignation, I think both should be implemented with the latter used as a way for users to specify they are OK with potentially reducing the security of the desktop environment to let the application he/she wants to run properly. This will lower users’ dissatisfaction and should result in a better security than bypassing some security properties for all applications. I am however worried that some stupid applications may be OK with creating snapshot capabilities from the command line, without requiring the user’s input. A packager would then grant the privileges to this application by default and thus, the mere fact of having this application installed will make your desktop non-confidential anymore." (Thanks to Patrick Guignot.)
The Linux Plumbers Conference has put out its "Call for Microconference Proposals" for the 2014 edition of the conference. It will be held in Düsseldorf, Germany on October 15-17, co-located with LinuxCon Europe. "A microconference is a collection of collaborative sessions focused on problems in a particular area of the Linux plumbing, which includes the kernel, libraries, utilities, UI, and so forth, but can also focus on cross-cutting concerns such as security, scaling, energy efficiency, and so forth. Good microconferences result in solutions to these problems and concerns, while the very best microconferences of course result in patches that implement those solutions. Topics that require significant slideware are probably better candidates for the refereed track than for a microconference." More information can be found on the LPC Participate page. The call for refereed-track proposals went out on January 29.
Lennart Poettering has announced the release of systemd 209. In the roughly five months since 208, systemd has seen a lot of changes including support for kdbus (albeit with an unstable API for now). Two new tools, systemd-networkd and systemd-socket-proxyd, have been added. Several libraries have been combined into a single libsystemd to reduce code duplication. Lots more changes are listed in the announcement. Unlike earlier releases, it is not yet available for Fedora Rawhide due to an ARM build problem. "This is a massive new release, it includes a lot of new code. You probably don't want to base your LTS release on this. We hope to return to a shorter release cycle now to stabilize the new code. Expect a couple of bugfix releases over the next weeks."

The LWN.net Weekly Edition for February 20, 2014 is available.
Debian has updated libtar (directory traversal).
openSUSE has updated poppler (11.4: multiple vulnerabilities).
Ubuntu has updated EC2 kernel (10.04 LTS: multiple vulnerabilities), kernel (10.04 LTS; 12.04 LTS; 12.10; 13.10: multiple vulnerabilities), linux-lts-quantal (12.04 LTS: multiple vulnerabilities), linux-lts-raring (12.04 LTS: multiple vulnerabilities), linux-lts-saucy (12.04 LTS: multiple vulnerabilities), and linux-ti-omap4 (12.04 LTS; 12.10; 13.10: multiple vulnerabilities).
The C11 standard added a number of new features for the C and C++ languages. One of those features — built-in atomic types — seems like it would naturally be of interest to the kernel development community; for the first time, the language standard tries to address concurrent access to data on contemporary hardware. But, as recent discussions show, it may be a while before C11 atomics are ready for use with the kernel — if they ever are — and the kernel community may not feel any great need to switch.

Gentoo has updated xpdf (multiple vulnerabilities from 2009 and 2010).
Version 2.17 of the GNU grep utility is out. "This release is notable for its performance improvements: we don't often see a 10x speed-up in a tool like grep." Other changes include the removal of the long-deprecated --mmap option.
Fedora has updated curl (F19: information disclosure), imapsync (F19: TLS botch), numpy (F20: insecure temp files), python3 (F20: code execution), xen (F19; F20: multiple vulnerabilities), and zarafa (F19; F20: denial of service).
Mageia has updated cxxtols (MG4: denial of service), denyhosts (MG3: denial of service), gnutls (certificate verification error), libgadu (buffer overflow), libpng (MG3: denial of service), libpng12 (MG4: denial of service), maradns (MG3; MG4: denial of service), pacemaker (MG3: denial of service), rawtherapee (denial of service), socat (denial of service), tntnet (information leak), and xbmc (denial of service).
openSUSE has updated pidgin, (13.1, 12.3: multiple vulnerabilities).
Linus has released 3.14-rc3, and he's on the verge of getting grumpy. "When I made the rc2 announcement, I mentioned how nice and small it was. I also mentioned that I mistrusted you guys, and that I suspected that some people were giggling to themselves and holding back their pull requests, evil little creatures like you are. And I hate being right." One assumes that the subsystem maintainers, having been warned, will be careful about what they send for the rest of the development cycle.
The Ubuntu Community Council has issued a statement regarding Canonical's requirement that binary redistributors (such as Linux Mint) obtain a license from Canonical. "We believe there is no ill-will against Linux Mint, from either the Ubuntu community or Canonical and that Canonical does not intend to prevent them from continuing their work, and that this license is to help ensure that. What Linux Mint does is appreciated, and we want to see them succeed." There is no real discussion on what is being licensed; it would appear to be a fairly mundane trademark issue stemming from the fact that Linux Mint distributes binary packages taken directly from the Ubuntu repository.
The South China Morning Post is reporting the demise of Red Flag, which is a government-backed Linux distribution by and for the Chinese people. "China’s best hope for a home-grown computer operating system to take on global giants like Microsoft lay in tatters after state-backed Red Flag Software was forced to close its doors for business. Founded in 2000 during the dot-com boom, Red Flag was once the world’s second-largest Linux distributor, providing desktop and server software built on top of the free and open-source Linux program. Despite its lofty goals and early success, Beijing-based Red Flag has gone out of business and terminated all its employment contracts on Monday, according to a report on the Sina news portal on Thursday."
Over at opensource.com, Red Hat's cloud evangelist Gordon Haff looks at the adoption of OpenStack through the lens of the adoption of Linux (and surrounding projects). "Early Linux success didn’t come about because it was better technology than Unix. For the most part it wasn’t. Rather it often won because it was less expensive than proprietary Unix running on proprietary hardware. It also gave users a choice of both distributions and hardware vendors as well as the ability to customize the code should they so choose. However, what has truly distinguished Linux and open source broadly over time is the power of the open source development models and the innovation that comes from communities around projects."
Fedora has updated icedtea-web (F19: insecure tmpfile use), imapsync (F20: TLS botch), libgadu (F20: code execution), maradns (F20: denial of service), pidgin (F19: multiple vulnerabilities), and python (F20: code execution).
Oracle has updated piranha (OL5: access restriction bypass).
Mark Shuttleworth responds to Debian's decision to go with systemd. "Nevertheless, the decision is for systemd, and given that Ubuntu is quite centrally a member of the Debian family, that’s a decision we support. I will ask members of the Ubuntu community to help to implement this decision efficiently, bringing systemd into both Debian and Ubuntu safely and expeditiously."

Milyen tapasztalataid vannak Ubuntu disztribúció upgrade-el kapcsolatban?
Simán le szokott menni, semmilyen probléma nem fordul elő.
Egy-két apróbb hiba/kisebb bug előfordul, de semmi zavaró.
Komolyabb hegesztés kell, mert néhány dolog elromlik/nem működik, idegesítő bugok jönnek elő.
Friss install kell, mert használhatatlan/nem indítható lesz a rendszer.
Nem upgradeltem még Ubuntut | csak az eredményre vagyok kíváncsi.
