Fedora Weekly News Issue 172
Welcome to Fedora Weekly News Issue 172 for the week ending April 19th, 2009.
This week Announcements rubs its hands with glee over the "Fedora 11" freeze. Similarly Artwork enthuses about "Fedora 11 Landing" with great Leonidas themes including a surprise for wide-screen setups. Developments gushes about "Presto and DeltaRPM Status" and SecurityWeek asks the interesting question "Who in the Linux World Would be Responsible for a Worm?". SecurityAdvisories faithfully lists updates that might just help avoid that worm. With a red face we draw your attention with an Erratum to last week's missing QualityAssurance beat. This week's QualityAssurance beat "Test Days" advertizes the upcoming minimal installation testing and reports in "Weekly meetings" that PulseAudio issues with snd-intel-hda and snd-intel8x0 are resolved. Translation reports on the availability of a bulky "Fedora 11 Installation Guide Ready for Translation". The FedoraWeeklyWebcomic joins us again and Ambassadors shares a neat list of LinuxFestNorthWest talks by Fedora folk.

Erratum: Missing QualityAssurance Beat in FWN#171
Last week (FWN#171) your painstaking QualityAssurance correspondent, Adam Williamson, wrote a very readable account of the activity around the UEFI BIOS replacement, Graphics-card Metrics and a lot more. Somehow we omitted to include this in the plaintext issue. With apologies to Adam and to our readers we suggest you take a look at our archived web version.
In this section, we cover announcements from the Fedora Project.

We're getting very close to the Fedora 11 release, and excitement is building.
Jesse Keating announced that we are now frozen for Fedora 11. "We've reached the final freeze, as well as mass branched. From this point on, builds from F-11/ will go to dist-f11-updates-candidate and builds from devel/ will go to dist-f12. dist-f11 itself is locked."
John Poelstra gave a final reminder to feature owners whose features are not at 100%. "Feature freeze has past and the following feature pages still need updates. Some have not been updated for several months. All need to be at 100% completion and their content set to reflect that."

This week saw two Test Days. The first was a follow-up on the Fedora 11 rewrite of Anaconda's storage device code. The second was on the Presto plugin for yum, which enables the use of deltarpms for updates. The Anaconda test day verified that many issues from the earlier test day had been resolved and turned up several new bugs, many of which have been fixed already. The Presto test day was surprisingly uneventful: there was good participation but few bugs were discovered, the system worked well and reliably for almost every test.
Next week's Test Day will be on the minimal platform feature, support for very small minimal installations. This is another test day which will require installation, so if you are interested in taking part, please make sure to have a spare system or partition on which you can install a Rawhide system. Of course, this week it only needs to be small!
The QA group weekly meeting was held on 2009-04-15. The full log is available. The group briefly discussed James Laska's plan to improve the customization possibilities for Test Day live CDs. James promised to send a mail to the list regarding his ideas here.
Adam Williamson reported on his progress in evaluating whether important bugs reported in the X driver Test Days are fully represented on the Fedora 11 release blocker bugs list. The nouveau maintainer, Ben Skeggs, has already reviewed all nouveau bugs. Review of intel and radeon bugs are in process together with the regular triagers for these components, Matej Cepl and Francois Cami.
Will Woods provided an update on his progress in checking on PulseAudio's readiness for a Fedora 11 release. He noted that some significant problems remained in two ALSA drivers - snd-intel-hda and snd-intel8x0 - which cause problems in PulseAudio. These drivers are used by a very large amount of current sound hardware. However, patches to fix several problematic cases have been added to the Rawhide kernel recently, and the remaining problems can be worked around if fixes are not integrated prior to release time, so it should be possible to release Fedora 11 with a fairly reliable PulseAudio. The group discussed whether it would make sense to schedule a Test Day for Intel audio chipsets, but concluded it was too close to release time and the Test Day schedule was already too busy to make it practical.
The Bugzappers group weekly meeting was held on 2009-04-14. The full log is available. The meeting opened with a call for the Bugzappers group to be proactive in adding serious bugs to the Fedora 11 Blocker and Target bug lists. Several group members expressed the concern that they would not be able accurately to identify which bugs should be added to the list, so Adam Williamson and James Laska promised to discuss the issue at the next QA meeting and see if there was a way to provide firmer policies and guidance in future.
The group agreed to delegate the creation and organization of a Wiki area covering SOPs (Standard Operating Procedures) to John Poelstra.
The discussion about how long to wait before closing NEEDINFO bugs was resolved by a proposal from John Poelstra: whether to close after 30 or 60 days will be left to the discretion of individual triagers, while if there is in future any co-ordinated team working to resolve stale NEEDINFO issues not handled by the initial triager, they will use the 60 days method.
The next QA weekly meeting will be held on 2009-04-22 at 1600 UTC in #fedora-meeting, and the next Bugzappers weekly meeting on 2009-04-21 at 1500 UTC in #fedora-meeting.
In this section the people, personalities and debates on the @fedora-devel mailing list are summarized.

Frozen for Fedora 11. Some Packages Still Not Built dist-f11
Jesse Keating announced that henceforth all F-11/ builds would go to dist-f11-updates-candidate and builds from devel/ would go to dist-f12. He asked for concerned parties to check that builds were being properly tagged.
In response to Mike Chambers' question Jesse confirmed that the nightly rawhide composes would consist of
Fedora 11 content until the GOLD packages were on their way out to the mirrors at which point the nightly rawhide composes would contain
Fedora 12 content.
On a related note Bill Nottingham asked maintainers of a list of packages not yet rebuilt in dist-f11 (with the attendant compiler and strong RPM hashes) to fix them if possible. Jesse Keating provided a slightly more aggressive list as an addendum.
Xorg Hacking Solves DontZapTom Callaway drew attention to a blog entry of Peter's which mentioned upstream patches by Julien Cristau (of Debian) to
xkeyboard-configand Peter's own patch to
Xserverwhich together make it possible to disallow zapping by default and also to turn zapping on with a
'setxkbmap -option terminate:ctrl_alt_bksp'. The net result is that it is possible to get zapping to work but the
XKB configuration needs to be set up properly and the DontZap option left disabled (as per the new default).
In discussion with Kevin Kofler Peter clarified the situation in which the new settings would take effect. Kevin responded that it appeared that for
KDE users zapping with Ctrl-Alt-BkSp would remain as before.
The above summary of an elegant technical solution ignores the long, and at times vitriolic, complaints about this change. A common trope occurring in some recent threads seems to be that changes are made by Red Hat employees who are implementing changes without community consultation and all work to a common game plan. Seth Vidal challenged the latter assumption:"In a survey of 10 RH employees you will find between 10 and 40 different opinions. sometimes more if you don't ask some of them to confine their comments to a limited amount of time." In any event it's worth noting that the resolution (which filters the "Terminate_Server" action in a manner consistent with the handling of other actions in xkb rulesets) was contributed upstream by a Red Hat employee. As a point of information Kevin Fenzi also made it clear that the change had not been instigated by FESCo.
The new options presented by Peter were in addition to those already suggested in the beta Release Notes.
Minesweeper Certified Solitaire Professionals Satisfied with DVD
Feedback suggested that retaining the games was preferred and dropping the development libraries made sense as the latest versions would be needed and could be obtained from the repositories anyway. Jesse later posted this was sufficient to achieve the desired image size.
Presto and DeltaRPM Status
The ability to download binary diffs of RPM packages has been offered for some time now on Fedora through the
Presto project and presto-enabled repositories. Interest is high enough in Presto's bandwidth-saving abilities that no fewer than three separate threads were started to ensure that it would function properly for
Warren Togami asked if
Presto would be enabled by default for
Fedora 11. Last month (2009-03-21) Jonathan Dieter reported that the use of
rpm had broken
deltarpm but that a patched version was available in rawhide. See FWN#166 for earlier coverage of the challenges and changes resulting from the introduction of stronger hashes.
Jonathan also reported that the changes necessary in infrastructure to build deltarpms had been done. These changes were made fairly rapidly thanks to work done by Michael Schroeder, the upstream
deltarpm developer. One issue that concerned Axel Thimm was the security with which checksums of deltarpms were being made. Till Maas and Jonathan Dieter provided reassurance that all deltarpms are generated from original rpms which needed to pass all verifications which
Martin Sourada was excited not just about
Presto but also about the slick new
Fedora 11. Martin was concerned about the issue of
Presto apparently not working well together. A BugZilla entry revealed that
PackageKit developer Richard Hughes quickly created a patch which Martin reported as working.
On 2009-04-16 Bill Nottingham added to the "Rawhide Report" that "[...] rawhide is composed with deltarpms against the prior rawhide. Due to a bug, this is only currently working on i386; it should be fixed for other arches tomorrow. Please test and report any issues."
Browser Plugins May Strip SELinux Protections
Dan worried that while "[a] confined nsplugin is a nice feature for confining plugins downloaded from the network. But if you run openoffice and evince from within nsplugin they get confined, causing the apps to not work properly." In response to Simo Sorce Dan explained that any attempt to write transition rules to enable said applications to work properly would create an easy avenue of attack. Simo wondered if it would be possible to either write a security wrapper to restrict the command line, or to get application developers to honor SELinux labels in some way.
Warren Togami shared that removing
mozplugger was "[...] something I always do. It seems to cause more problems than it solves [...]" and James Morris expanded upon this with instructions "[...] on both removing mozplugger and restoring the security protections of SELinux. Simply removing the package isn't enough[.]" James questioned "[...] how a package which breaks a security feature not only made it into the repo, but how it became enabled by default[?]"
- Mozplugger describes itself as "[a] general purpose Mozilla plugin module that allows the user to embed and launch their favorite application to handle the various different types of media found on the Internet." http://mozplugger.mozdev.org/
Getting Rid of /usr for Fedora 12 ?
Lennart Poettering cheerfully invited any inclined parties to a flamefest over the elimination of the /usr directory. Lennart suggested that recent history indicated that more files were being moved from /usr to / and that confusion between the two was a source of error from some packages.
Enthusiasm for both the flamewar and the proposal was low.
A forceful and well-argued objection was made by Konstantin Ryabitsev on the basis that he liked to keep /boot and /usr on their own partitions and use a LUKS-encrypted LVM for everything else. Konstantin emphasized this was especially well-suited to portable machines which need to conserve power and are more likely to need encryption.
Ralf Corsepius invoked the FHS on /usr and the need to contain non-essential packages unavailable at certain boot stages therein. Chris Adams added that symlinking /usr to / had been shown to break
Lennart explained how /etc could be made read-only and adduced OpenSUSE, Debian and Gentoo as further evidence that a read-only root could be attained. Callum Lerwick pined for the days of floppy disks.
Toshio Kuratomi completely declined to play and asked: "I'm hereby giving notice that I don't have time to read obvious flamefests anymore. Once this thread concludes, please summarize whatever the pros and cons are and send it to the packaging committee to discuss and vote on."

Fedora 11 Installation Guide Ready for Translation
Ruediger Landmann announced the availability of the Fedora 11 Installation Guide for translation. Due to import of relevant content from the Red Hat Enterprise Linux Installation Guide into this Guide, the content has substantially increased. The final translation due date is 14th of May 2009 with an extension of 1 week for additional corrections. The .po files would be refreshed on April 28th 2009, to correct errors identified until that date.

Malicious Activity Grows in 2008
2008 Saw a surge in malicious code activity  This is a disturbing trend, and for the underground, this is easy money. The threat will continue to grow until either the money dries up (unlikely) or the difficulty of exploiting this is greater than the potential gain. Right now it looks like the trend will continue for several years.
Who in the Linux World Would be Responsible for a Worm ?
Last week OSNews asked a rather interesting, but easily answered question: OSNews Asks: Who'd Be Responsible for a Linux Conficker?  The world of Open Source security is mostly a process that happens behind the scenes, but is quite effective. There is a wiki called OSS-Security  that provides a number of links to various groups. In the event of something like a worm, the vast majority of the effort would end up happening on the Vendor Security (vendor-sec) mailing list. This is a group of trusted Open Source distributors that communicate in private in an effort to keep the end users of Open Source software secure. To date this group has been working out quite well, and the members are very used to solving security flaws in a cooperative manner. In the event of a widespread Linux worm, there would be many tired people, and quite a lot of vendor-sec emails.
