Communication

Respond to queries from Debian users and developers on the mailing lists and IRC

Sponsors The ifenslave and apt-listchanges work was sponsored by my employer. All other work was done on a volunteer basis.

While waiting for my priority date to become current, and with enough "quarantine time" on my hand, i just come up with a very simple Python tool to parse the USCIS Visa Bulletin to gather some data from that.

You can find code and images in this GitHub repo.

For now it only contains a single plot for the EB3 final action date; it answers a simple question: how many months ago your priority date should be if you want to file your AOS on that month. We started from FY2016, to cover the final full year of the Obama administration.

If you're interested in more classes/visas, let me know and the tool could be easily extended to cover that too. PRs are always welcome.

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian. If you re interested in Java, Games and LTS topics, this might be interesting for you. Debian Games

I sponsored a new release of hexalate for Unit193 and icebreaker for Andreas Gnau. The latter is a reintroduction.
New upstream releases this month: freeorion and hyperrogue.
I backported freeciv and freeorion to Stretch.

Debian Java

New upstream releases and one update: sweethome3d, sweethome3d-furniture, sweethome3d-furniture-editor, sweethome3d-textures-editor (update), libsambox-java, libsejda-java, pdfsam, easymock, jboss-modules, jboss-xnio and undertow.
I fixed one RC bug in libsejda-io-java (#874494) and investigated another one (#869266) in commons-httpclient which could be closed.
The new build-dependencies of jboss-xnio, wildfly-client-config and wildfly-common, were accepted into the archive this month.
I spent some quality time on fixing #874579 in libhibernate-validator-java. This was the last blocking bug for pdfsam which I could finally upload to unstable. It s a really great JavaFX application. Check it out!
I sponsored another update of libimglib2-java for Ghislain Vaillant and simplyhtml, freeplane and knopflerfish-osgi for Felix Natter.
I also fixed RC bug #871348 in robocode, a Java programming game and #871347 in tycho.

Debian LTS This was my nineteenth month as a paid contributor and I have been paid to work 15,75 hours on Debian LTS, a project started by Rapha l Hertzog. In that time I did the following:

From 18. September to 24. September I was in charge of our LTS frontdesk. I triaged bugs in poppler, binutils, kannel, wordpress, libsndfile, libexif, nautilus, libstruts1.2-java, nvidia-graphics-drivers, p3scan, otrs2 and glassfish.
DLA-1108-1. Issued a security update for tomcat7 fixing 1 CVE.
DLA-1116-1. Issued a security update for poppler fixing 3 CVE.
DLA-1119-1. Issued a security update for otrs2 fixing 4 CVE.
DLA-1122-1. Issued a security update for asterisk fixing 1 CVE. I also investigated CVE-2017-14099 and CVE-2017-14603. I decided against a backport because the fix was too intrusive and the vulnerable option is disabled by default in Wheezy s version which makes it a minor issue for most users.
I submitted a patch for Debian s reportbug tool. (#878088) During our LTS BoF at DebConf 17 we came to the conclusion that we should implement a feature in reportbug that checks whether the bug reporter wants to report a regression for a recent security update. Usually the LTS and security teams receive word from the maintainer or users who report issues directly to our mailing lists or IRC channels. However in some cases we were not informed about possible regressions and the new feature in reportbug shall ensure that we can respond faster to such reports.
I started to investigate the open security issues in wordpress and will complete the work in October.

Misc

I packaged a new version of xarchiver. Thanks to the work of Ingo Br ckl xarchiver can handle almost all archive formats in Debian now.

QA upload

I did a QA upload of xball, an ancient game from the 90ies that simulates bouncing balls. It should be ready for another decade at least.

Thanks for reading and see you next time.

Sent three pull requests to git-buildpackage, a tool to assist in Debian packaging from Git repositories:
- Make pq --abbrev= configurable. (#872351)
- Use build profiles to avoid installation of test dependencies. (#31)
- Correct "allow to" grammar. (#30)
Updated travis.debian.net (my hosted service for projects that host their Debian packaging on GitHub to use the Travis CI continuous integration platform for testing):
- Move away from deb.debian.org; Travis appears to be using a HTTP proxy that strips SRV records. (commit)

Assigned two pull requests to the Redis key-value database store to correct "did not received" and "faield" typos. (#4216 & #4215).

Reproducible builds

Whilst anyone can inspect the source code of free software for malicious flaws, most software is distributed pre-compiled to end users. The motivation behind the Reproducible Builds effort is to allow verification that no flaws have been introduced either maliciously or accidentally during this compilation process by promising identical results are always generated from a given source, thus allowing multiple third-parties to come to a consensus on whether a build was compromised. I have generously been awarded a grant from the Core Infrastructure Initiative to fund my work in this area. This month I:

Presented a status update at Debconf17 in Montr al, Canada alongside Holger Levsen, Maria Glukhova, Steven Chamberlain, Vagrant Cascadian, Valerie Young and Ximin Luo.
I worked on the following issues upstream:
- glib2.0: Please make the output of gio-querymodules reproducible. (...)
- gcab: Please make the output reproducible. (...)
- gtk+2.0: Please make the immodules.cache files reproducible. (...)
- desktop-file-utils: Please make the output reproducible. (...)
Within Debian:
- My work as Debian Project Leader (DPL) is covered in my monthly Bits from the DPL email to debian-devel-announce.
- Created isdebianreproducibleyet.com.
- Sent a patch to dpkg to sort the "unused substitution" warnings. (#870221)
- Added a script to devscripts to report on reproducibility status of installed packages. (#872514)
- Modified the Debian archive tools (dak) to automatically reject packages which do not bump their date in debian/changelog. (debian-devel post)
- Fixed an QA issue in snappy that was caught by the reproducible builds continuous integration framework. (#872226)
- I submitted three patches to fix specific reproducibility issues in grap, isa-support & python-numpy.
- Finally, I also performed two non-maintainer uploads (NMUs) for jsmath-fonts (#792319) and xvier (#777330) to make their builds reproducible.
Categorised a large number of packages and issues in the Reproducible Builds "notes" repository.
Worked on publishing our weekly reports. (#118, #119, #120, #121 & #122)

I also made the following changes to our tooling:

diffoscope

diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues.

Use name attribute over path to avoid leaking comparison full path in output. (commit)
Add missing skip_unless_module_exists import. (commit)
Tidy diffoscope.progress and the XML comparator (commit, commit)

disorderfs

disorderfs is our FUSE-based filesystem that deliberately introduces non-determinism into directory system calls in order to flush out reproducibility issues.

Add a simple autopkgtest smoke test. (commit)

[DSA 3869-1] tnef security update for one CVE

For [DLA 948-1] dropbear and [DLA 958-1] libonig I only did the LTS bookkeeping and sent the DLA. The icu upload would not have been possible without the help of Roberto. I also tried to work on jasper, libxml2, libytnef and swftools but unfortunately all upstreams did not finish their respective patches this month, so maybe there will be an upload in June. Other stuff Again this has been a busy LTS month, so I only uploaded a new version of smstools, which closed most of its bugs and adopted adopted ptpd as DOPOM. As a prerequisite of wview I uploaded radlib. Unfortunately I could not do anything for wview, so work on this has to be postponed. Another new package is te923con, which I hope is able to read data from my weather station. Last but no least I fixed an RC bug in alljoyn-services-1504.

Debian Long Term Support (LTS) This is my monthly Debian LTS report. My time this month was spent working on various hairy security issues, most notably XBMC (now known as Kodi) and yaml-cpp.

Kodi directory transversal I started by looking in CVE-2017-5982, a "directory traversal" vulnerability in XBMC (now known as Kodi) which is a technical term for "allow attackers to read any world-readable file on your computer from the network". It's a serious vulnerability which has no known fix. When you enable the "remote control" interface in Kodi, it allows anyone with the password (which is disabled by default) to download any files Kodi has read access to on the machine it's running. Considering Kodi is often connected to multiple services, this may mean elevated compromise and more nasty stuff. I furthered the investigation done with my own analysis which showed the problem is difficult to solve: Kodi internally uses the facility to show thumbnails and media to the user, and there are no clear way of restricting which paths Kodi should have access to. Indeed, Kodi is designed to access mounted file systems and paths in arbitrary locations. In Debian bug #855225, I further confirmed confirmed wheezy and jessie-backports as vulnerable and therefore showed with good certainty that stretch and sid are vulnerable as well. I also suggested possible workaround, but at this point, it's in upstream's hands, as the changes will be intrusive. The file transfer mechanism need to be revamped all over Kodi, or authentication (with a proper password policy), need to be enforced.

Squirrelmail Next I looked at that old webmail software, Squirrelmail, which suffers from a remote code execution vulnerability (CVE-2017-7692) when sending mails with sendmail on the commandline. This is arguably an edge case, but considering the patch was simple, I figured I would provide an update to the LTS community. I tried to get a coordinated release for jessie, since the code is the same, but this wasn't completed at the time of writing. A patch is available and will hopefully be picked up by another LTS worker soon.

Fop and Batik Those issues (CVE-2017-5661 and CVE-2017-5662) were more difficult. The patches weren't clearly documented and there were no upstream references other than security advisories for the first release in years (in the case of batik) or months (in the case of fop), which made it hard to track down the issues. Fortunately, I was able to track down the upstream issues (FOP-2668 and BATIK-1139) where I got confirmation on what the proper fixes were. I could then release DLA-927-1 and DLA-926-1 with the backported patches. I do not use fop or batik. In fact, even after reading the homepage of both products, I couldn't quite figure out what use people could possibly have for that thing. Before uploading the packages, I therefore made packages available for testing for fop and batik.

libsndfile Next up was libsndfile which a bunch of overflows when parsing various audio files. I backported a patch for CVE-2017-7585 CVE-2017-7586 and CVE-2017-7741 which all seemed to be fixed by a single patch usptream. CVE-2017-7742 was also fixed, although with a separate patch. In all of those, i could only test CVE-2017-7741 and CVE-2017-7742, as the others were missing test cases. I provided a test package for a few days then I also figured it would be best to incorporate the security fixes done in stable, which brought in fixes for CVE-2015-7805, CVE-2014-9756 and CVE-2014-9496. So in the end, I ported patches from wheezy to jessie and uploaded the jessie version (reverting certain build changes) into wheezy and uploaded DLA-928-1 with the results.

yaml-cpp I then turned to yaml-cpp, a C++ parser for YAML. This one didn't have a known upstream fix, but I figured I would give it a shot anyways. I ended up writing my first C++ code in years which is still pending review and merge upstream. It's not an easy problem to fix: this is basically an excessive recursion problem that can be used to smash the stack. I figured I could introduce a recursion limit, but as the discussion showed, this is a limited approach: stack size varies on different platforms and it's not easy to find the right limit. The real solution is to rewrite the code to avoid recursion but that's a major code refactoring I didn't feel belong in a LTS update. Besides, this could be better handled by upstream, so I will leave things at that for now. It does make you wonder how much code out there is recursing on untrusted data structures...

kedpm Finally, a friend over at Koumbit.org reported Debian bug #860817, as information leak in kedpm, a password manager I previously maintained. I requested and got assigned CVE-2017-8296 and provided a fix for wheezy and jessie. For unstable and the coming stretch release, I have requested kedpm to be completely removed from Debian (Debian bug #860817) which involved a release notes update (Debian bug #861277). It's unfortunate to see software go, but kedpm wasn't maintained. I wasn't the original author: I just gave a few patches and ended up maintaining that software and not using it. It's a bad situation to be in, as you don't really know what's working and not with the tools you are supposed to be responsible for. There are more modern alternatives available now and I encourage everyone to switch.

Triage Looking for more work, I peeked a bit in the secretary tasks to triage some pending issues. I found that trafficserver could be crashed with simple requests (CVE-2017-5659) so I looked into that issue. My analysis showed that the patch is long and complex and could be difficult to backport to the old version available in wheezy. I also couldn't reproduce the issue in wheezy, so it may be a bug introduced only later, although I couldn't confirm that directly. I also triaged wireshark, where I just noted the maintainer expressed concern that we were taking up issues too fast and will probably take care of this one. I also postponed various issues in GnuTLS (marked "no-dsa") as they affect only a (unfortunately) rarely used part of GnuTLS that has been removed in later version: OpenPGP support.

Other free software work

Debiman I finally got around contributing to the debiman project. I worked on ensuring that there is a dman compatibility in debiman, by shipping dman in the debian-goodies package (Debian bug #860920). I also submitted a pull request to fix the fix about page title, document the custom assets repository, fix a stray bracket and link to the link to venerable man7.org project After a discussion on IRC, I also filed a few more issues:

redirect bpf to bpf.2, not bpf.4freebsd

redirect to unstable by default

arrows missing in table of contents

automatically collapse long links

old ?query= parameter ignored/failing

I'm happy to be able to contribute to this important service and I hope the new FAQ I created will be online soon!

XMonad and Emacs I started using writeroom-mode again as part of my work on LWN. As it turns out, my setup was not exactly working: I had to port my config to the new version and windows weren't "sticky" as they should be, a known issue with Xmonad. Indeed, Xmonad doesn't obey the "static" or "all desktops" standard directives. Writeroom is a "distraction-free writing" mode for Emacs, so the irony of working on such a deep distraction in establishing a distraction free environment is not lost on me. Needing to scratch that particular itch, and with the help of clever people from the IRC channel, I was able to make Emacs tell Xmonad to show its window (or "frame" as Emacs likes to call it) on all desktops. This involved creating a new function which I think could be useful in the CopyWindow library:

--   Toggle between "copyToAll" or "killAllOtherCopies". Copies to all
-- workspaces, or remove from all other workspaces, depending on
-- previous state (checked with "wsContainingCopies").
copyToAllToggle :: X ()
copyToAllToggle = do
    -- check which workspaces have copies
    copies <- wsContainingCopies
    if null copies
      then windows copyToAll -- no workspaces, make sticky
      else killAllOtherCopies -- already other workspaces, unstick

There are probably better ways of implementing this directly in the CopyWindow code - wsContainingCopies, in particular, is probably overkill. But it's all I can use directly from my xmonad.hs, so that's what I did. The other bit I needed was something to trigger that function from the outside. I rejected the ServerMode hook because it looked a bit too complicated and there is a built-in facility within X that works without this, which, from Emacs' point of view, is the x-send-client-message function. So I made up a new message identifier and wrote a event hook handler to process it:

--   handle X client messages that tell Xmonad to make a window appear
-- on all workspaces
--
-- this should really be using _NET_WM_STATE and
-- _NET_WM_STATE_STICKY. but that's more complicated: then we'd need
-- to inspect a window and figure out the current state and act
-- accordingly. I am not good enough with Xmonad to figure out that
-- part yet.
--
-- Instead, just check for the relevant message and check if the
-- focused window is already on all workspaces and toggle based on
-- that.
--
-- this is designed to interoperate with Emacs's writeroom-mode module
-- and called be called from elisp with:
--
-- (x-send-client-message nil 0 nil "XMONAD_COPY_ALL_SELF" 8 '(0))
myClientMessageEventHook :: Event -> X All
myClientMessageEventHook (ClientMessageEvent  ev_message_type = mt, ev_data = dt ) = do
  dpy <- asks display
  -- the client message we're expecting
  copyAllMsg <- io $ internAtom dpy "XMONAD_COPY_ALL_SELF" False
  -- if the event matches the message we expect, toggle sticky state
  when (mt == copyAllMsg && dt /= []) $ do
    copyToAllToggle
  -- we processed the event completely
  return $ All True

All that was left was to hook that into Emacs, and I was done! Whoohoo! Full screen total domination, distraction free work!

I would love to hear from others what they think of that approach, if they have improvements or if the above copyToAllToggle function could be merged in. Ideally, Xmonad would just parse the STICKY client messages and do the right thing - maybe even directly in CopyWindow - but I have found this enough Haskell for one day. You can see the diff on my home directory to see exactly the changes involved to make this configuration work.

Emacs packaging Speaking of Emacs, after complaining in the noisy `#emacs` IRC channel about the poor TLS configuration of marmelade.org -- and filing a bug (Debian bug #861106) regarding the use of SHA-1 in certificate pinning -- I was told we shouldn't expect trust from third-party ELPA repositories. Marmelade seems to be dead, as the maintainer is "behind the great firewall of China" and MELPA still hasn't figured out how to sign packages. In the end, it seems like there are tons of elpa packages in Debian and that if your favorite one is missing, that's a bug that can be filed and fixed. I first discovered that 6 of the packages I used were already packaged:

elpa-notmuch

elpa-ledger

elpa-use-package

elpa-markdown-mode

elpa-go-mode

elpa-anzu

And so I went ahead and filed a ton more bugs for the packages I am using but that aren't in Debian just yet:

company-go: Debian bug #861177

elpy: Debian bug #861174

markdown-toc: Debian bug #861128

multiple-cursors: Debian bug #861127

writegood-mode: Debian bug #861125

writeroom-mode: Debian bug #861124

Of those, I can't recommend multiple-cursors (MC) enough: I used it at least 4 times just writing this text. It's just awesome. The other ones are also all great in their own right of course, but I feel they are more specific to my workflow whereas MC is just amazing.

ikiwiki I did some more work on ikiwiki the software driving this blog. I created a new plugin to, at least, fix anchors in the table of contents to be human readable. This is something I had done on the MoinMoin wiki almost a decade ago -- which I called then NicerHeadingIds and that I have always found frustrating with Ikiwiki. It turns out the problem was both easier and hairier than I thought. Right from the start, something weird was happening: something was already adding nice headings, but they were somewhat broken. It turns out that multimarkdown already inserts those headers, but I wasn't satisfied with the way they were generated. But even worse, I had the headinganchors plugin enabled, but that plugin wasn't taking effect, because of multimarkdown. And even if it would take effect, it doesn't behave well with non-ASCII characters, which gets turned in their numeric presentation. So I also wrote the i18nheadinganchors plugin that creates better headings and patched the toc plugin so that it can reuse existing anchors if they exist, while keeping backwards compatibility. I hope this gets merged in a future ikiwiki release so I do not have to carry this patch locally too long... In other news, I have upgraded the ikiwiki-hosting package to the latest version and sent a patch upstream to provide HSTS support.

Other stuff I have migrated all my public repos hosted on my home server to either Gitlab.com or Github. I also have repositories on 0xacab and it seemed ludicrous to have 4 different, canonical, places where my code was hosted. I have now about 40 different projects on Gitlab and about 60 on Github, although most of the latter are forks of existing projects. I also made a manpage for stressant and moved the documentation to RTFD which makes it neatly accessible. I also made small incremental improvements (like `--directory` support). I installed Rainloop on this server to give a nice, mobile-friendly webmail. Instructions to replicate this setup are in mail. In the constant git-annex documentation effort, I tried to draft a user guide that could be a basis for restructuring the documentation to be more easily accessible. I also helped a friend put his documentation on the wiki in splitting a repository. Finally, I also looked into Android stuff a little more. I wrote a usability review of the F-Droid privileged extension that will bring good changes, I hope. I also opened the discussion regarding reproducible builds to try and clarify exactly how those worked to help the Wallabag people ship consistently signed alphas. So far, it seems that it will remain a standard practice on F-Droid to ship packages that are not signed by the official upstream signature, unfortunately, unless upstream provides a reproducible build that is publicly available... Switching to such build is also a hairy issue, as, obviously, the signature changes, which raises the alarm we are trying to avoid in the first place.

Chris Lamb (4)

diffoscope development diffoscope 67 was uploaded to unstable by Chris Lamb. It included contributions from :

[ Chris Lamb ]
* Optimisations:
  - Avoid multiple iterations over archive by unpacking once for an ~8X
    runtime optimisation.
  - Avoid unnecessary splitting and interpolating for a ~20X optimisation
    when writing --text output.
  - Avoid expensive diff regex parsing until we need it, speeding up diff
    parsing by 2X.
  - Alias expensive Config() in diff parsing lookup for a 10% optimisation.
* Progress bar:
  - Show filenames, ELF sections, etc. in progress bar.
  - Emit JSON on the the status file descriptor output instead of a custom
    format.
* Logging:
  - Use more-Pythonic logging functions and output based on __name__, etc.
  - Use Debian-style "I:", "D:" log level format modifier.
  - Only print milliseconds in output, not microseconds.
  - Print version in debug output so that saved debug outputs can standalone
    as bug reports.
* Profiling:
  - Also report the total number of method calls, not just the total time.
  - Report on the total wall clock taken to execute diffoscope, including
    cleanup.
* Tidying:
  - Rename "NonExisting" -> "Missing".
  - Entirely rework diffoscope.comparators module, splitting as many separate
    concerns into a different utility package, tidying imports, etc.
  - Split diffoscope.difference into diffoscope.diff, etc.
  - Update file references in debian/copyright post module reorganisation.
  - Many other cleanups, etc.
* Misc:
  - Clarify comment regarding why we call python3(1) directly. Thanks to J r my
    Bobbio <lunar@debian.org>.
  - Raise a clearer error if trying to use --html-dir on a file.
  - Fix --output-empty when files are identical and no outputs specified.
[ Reiner Herrmann ]
* Extend .apk recognition regex to also match zip archives (Closes: #849638)
[ Mattia Rizzolo ]

Troubleshooting OBS

Generate a test environment by creating Stretch/SID VM Really, use whatever suits you best, but please create an untrusted test environment for this one. In the current tutorial it assumes $hostname is stretch , which should be stretch or sid suite. Be aware that copy & paste configuration files from current post might lead you into broken characters (i.e. ). Debian Stretch weekly netinst CD Enable experimental repository

# echo "deb http://httpredir.debian.org/debian experimental main" >> /etc/apt/sources.list.d/experimental.list
# apt-get update

Install and setup OBS server, api, worker and osc CLI packages

# apt-get install obs-server obs-api obs-worker osc

In the install process mysql database is needed, therefore if mysql server is not setup, a password needs to be provided.
When OBS API database obs-api is created, we need to pick a password for it, provide opensuse . The obs-api package will configure apache2 https webserver (creating a dummy certificate for stretch ) to serve OBS webui.
Add stretch and obs aliases to localhost entry in your /etc/hosts file.
Enable worker by setting ENABLED=1 in /etc/default/obsworker
Try to connect to the web UI https://stretch/
Login into OBS webui, default login credentials: Admin/opensuse).
From command line tool, try to list projects in OBS

 $ osc -A https://stretch ls

Accept dummy certificate and provide credentials (defaults: Admin/opensuse)
If the install proceeds as expected follow to the next step. Ensure all OBS services are running

$ osc -A https://stretch:443 co test ; cd test
$ mkdir hello ; cd hello ; apt-get source -d hello ; cd - ; 
$ osc add hello 
$ osc ci -m "New import" hello

The package should go to dispatched state then get in blocked state while it downloads build dependencies from DoD link, eventually it should start building. Please check the journal logs to check if something went wrong or gets stuck. Visit webUI to check hello package build state OBS logging to the journal Check in the journal logs everything went fine:

$ sudo journalctl -u obsdispatcher.service -u obsdodup.service -u obsscheduler@x86_64.service -u obsworker.service -u obspublisher.service

Troubleshooting Currently we are facing few issues with web UI:

And there are more issues that have not been reported, please do reportbug obs-api .

Here is my monthly update covering what I have been doing in the free software world (previous month):

Fixed a number of instances in the Django web development framework where methods had mutable defaults arguments such as lists or dictionaries. (#7253)
Made a large number of improvements to travis.debian.net, my hosted service for projects that host their Debian packaging on GitHub to use the Travis CI continuous integration platform to test builds on every update:
- Worked with Evgeni Golov to run autopkgtest and autodep8 tests after builds. (#23, #24 & #25)
- Ensured that all remote branches are created locally so that packages that specify options such as pristine_tar=True in debian/gbp.conf work as expected. (commit)
- Fixed an issue where checking out other branches did not reliably not work due to Travis cloning the repository with --depth=50. (#21)
- Updated the documentation after prompting from Valerie Young. (db7238 & 470d24)
Improved my Chrome extension for the FastMail web interface to collapse whitespace when appending to the subject. (#9)
Submitted a pull request for the Handbrake video transcoder to make the build reproducible. (#320)
Updated the configuration for my OpenWRT-based router (a device I use as a range extender and to save tedious reconfiguration of all my wifi devices in new locales) to enter a "fallback" mode if it cannot connect to the client network. This works around a longstanding "wontfix" upstream issue. (diff)
Updated django-agpl, my reusable Django application to assist in releasing projects under the GNU Affero General Public License:
- Merged support from defivelo to support Django 1.8. (#1)
- Improved the code quality & testability throughout the package. (diff)
Filed in issue in Mailvelope (a browser extension for OpenPGP encryption) to support composing/viewing messages in a fixed-width font. (#422)
Blogged about how to write your first Lintian check as well as on the progress bar I added to Diffoscope.

Reproducible builds

Whilst anyone can inspect the source code of free software for malicious flaws, most Linux distributions provide binary (or "compiled") packages to end users. The motivation behind the Reproducible Builds effort is to allow verification that no flaws have been introduced either maliciously and accidentally during this compilation process by promising identical binary packages are always generated from a given source. My work in the Reproducible Builds project was also covered in our weekly reports #71, #72, #71 & #74. I made the following improvements to our tools:

diffoscope

diffoscope is our "diff on steroids" that will not only recursively unpack archives but will transform binary formats into human-readable forms in order to compare them.

Added a global Progress object to track the status of the comparison process allowing for graphical and machine-readable status indicators. I also blogged about this feature in more detail.
Moved the global Config object to a more Pythonic "singleton" pattern and ensured that constraints are checked on every change.

disorderfs

disorderfs is our FUSE filesystem that deliberately introduces nondeterminism into the results of system calls such as readdir(3).

Display the "disordered" behaviour we intend to show on startup. (#837689)
Support relative paths in command-line parameters (previously only absolute paths were permitted).

strip-nondeterminism

strip-nondeterminism is our tool to remove specific information from a completed build.

Fix an issue where temporary files were being left on the filesystem and add a test to avoid similar issues in future. (#836670)
Print an error if the file to normalise does not exist. (#800159)
Testsuite improvements:
- Set the timezone in tests to avoid a FTBFS and add a File::StripNondeterminism::init method to the API to to set tzset everywhere. (#837382)
- "Smoke test" the strip-nondeterminism(1) and dh_strip_nondeterminism(1) scripts to prevent syntax regressions.
- Add a testcase for .jar file ordering and normalisation.
- Check the stripping process before comparing file attributes to make it less confusing on failure.
- Move to a lookup table for descriptions of stat(1) indices and use that for nicer failure messages.
- Don't uselessly test whether the inode number has changed.
Run perlcritic across the codebase and adopt some of its prescriptions including explicitly using oct(..) for integers with leading zeroes, avoiding mixing high and low-precedence booleans, ensuring subroutines end with a return statement, etc.

I also submitted 4 patches to fix specific reproducibility issues in golang-google-grpc, nostalgy, python-xlib & torque.

Debian

https://lamby-www.s3.amazonaws.com/yadt/blog.Image/image/original/28.jpeg

I attended the Debian Bug Squashing Party (BSP) in Salzburg, Austria where 70+ "release-critical" bugs were fixed. Sincere thanks to Bernd Zeimetz (bzed) for organising and Conova for sponsoring/hosting. The event was covered by the Salzburg Cityguide.
I attended NixOS user group in London, England.
Niels Thykier granted me commit access to the Lintian Git repository and I added myself to the debian/copyright there.
Filed an ITP for the roughtime secure time synchronisation client and server. This is blocked on packaging the Bazel build system. (#838416)

Patches contributed

Lintian:
- Tag debian/*.maintscript files that include "maint-script-parameters". (#838195.)
- Tag initscripts that use /lib/lsb/init-functions without the corresponding dependency on lsb-base. (#838997)
- Catch false positives in systemd-service-file-missing-install-key check. (#837057)

Debian LTS

This month I have been paid to work 12.75 hours on Debian Long Term Support (LTS). In that time I did the following:

"Frontdesk" duties, triaging CVEs, etc.
Issued DLA 608-1 for mailman fixing a CSRF vulnerability.
Issued DLA 611-1 for jsch correcting a path traversal vulnerability.
Issued DLA 620-1 for libphp-adodb patching a SQL injection vulnerability.
Issued DLA 631-1 for unadf correcting a buffer underflow issue.
Issued DLA 634-1 for dropbear fixing a buffer overflow when parsing ASN.1 keys.
Issued DLA 635-1 for dwarfutils working around an out-of-bounds read issue.
Issued DLA 638-1 for the SELinux policycoreutils, patching a sandbox escape issue.
Enhanced Brian May's find-work --unassigned switch to take an optional "except this user" argument.
Marked matrixssl and inspircd as being unsupported in the current LTS version.

Uploads

python-django 1:1.10.1-1 New upstream release and ensure that django-admin startproject foo creates files with the correct shebang under Python 3.
gunicorn:
- 19.6.0-5 Don't call chown(2) if it would be a no-op to avoid failure under snap.
- 19.6.0-6 Remove now-obsolete conffiles and logrotate scripts; they should have been removed in 19.6.0-3.
redis:
- 3.2.3-2 Call ulimit -n 65536 by default from SysVinit scripts to normalise the behaviour with systemd. I also bumped the Debian package epoch as the "2:" prefix made it look like we are shipping version 2.x. I additionaly backported this upload to Debian Jessie.
- 3.2.4-1 New upstream release, add missing -ldl for dladdr(3) & add missing dependency on lsb-base.
python-redis (2.10.5-2) Bump python-hiredis to Suggests to sync with Ubuntu and move to a machine-readable debian/copyright. I also backported this upload to Debian Jessie.
adminer (4.2.5-3) Move mysql-server dependencies to default-mysql-server. I also backported this upload to Debian Jessie.
gpsmanshp (1.2.3-5) on behalf of the QA team:
- Move to "minimal" debhelper style, making the build reproducible. (#777446 & #792991)
- Reorder linker command options to build with --as-needed (#729726) and add hardening flags.
- Move to machine-readable copyright file, add missing #DEBHELPER# tokens to postinst and prerm scripts, tidy descriptions & other debian/control fields and other smaller changes.

I sponsored the upload of 5 packages from other developers:

stressapptest (1.0.6-3) Make the build reproducible. (#831587)
zeroinstall-injector (2.12-1) Fix FTBFS due to failing tests. (#837226)
libisofs, libburn & libisoburn (1.4.6-1) New upstream releases.

I also NMU'd:

cfingerd (1.4.3-3.2) Fix a FTBFS due to lack of "." in Perl's @INC. (#837267)
dot-forward (0.71-2.1) Make the build reproducible. (#776760)
8 packages to remove dependencies on hardening-wrapper and hardening-includes: switchsh, pwauth, grap, libmsn, libevocosm, passwordmaker-cli, srtp & netatalk.
12 packages that were using now-unsupported debhelper levels: freetable, alsamixergui, linklint, openjade, python-cddb, dh-kpatches, dsh, jfsuils, lpr, myspell & libxml-dumper-perl.

RC bugs I filed 37 FTBFS bugs against csoundqt, cups-filters, dymo-cups-drivers, easytag, erlang-p1-oauth2, erlang-p1-sqlite3, erlang-p1-xmlrpc, erlang-redis-client, fso-datad, gnome-python-desktop, gnote, gstreamermm-1.0, gtkglextmm, gupnp-dlna, haskell-hmatrix-gsl, jdeb, kryo-serializers, libcmrt, libfso-glib, libmonitoring-livestatus-perl, librasterlite2, network-manager, print-manager, psychtoolbox-3, python-3to2, python-tidylib, recutils, slang2, snd, sugar, tj3, transmission-remote-gtk, vino, webkit2pdf, xml-core, xml-core & xml-core. I additionally filed 2 "important" bugs for packages that access the internet during build against gnupg2 & libgdata.

FTP assistant This month I marked 352 packages for accept and rejected 61 of them. I had to send only 15 emails to maintainers. I also started to work on #796095 and #796784, but my first patch was rejected. So expect more to come here Squeeze LTS This was my seventeenth month that I did some work for the Squeeze LTS initiative, started by Raphael Hertzog at Freexian. Due to Toshiba becoming the first platinum sponsor, I got a workload of 21.25h. This is a new and delightful record! Altogether I uploaded those DLAs:

[DLA 341-1] php5 security update
[DLA 343-1] libpng security update
[DLA 355-1] libxml2 security update
[DLA 356-1] libsndfile security update

I also started to work on two bugs that were filed against the pseudo-package ftp.debian.org, which are somehow related to the security team: #796095 and #796784 (see above). Moreover I started to work on the next php5 upload, which will happen at the end of December. As more and more people work at the LTS frontdesk now, this month I could chill out a bit and let the others do the work. Other stuff As the Advent season started again I would also like to draw some attention to the Debian Med Advent Calendar. It was announced here and like the past years, the Debian Med team starts a bug squashing event from the December 1st to 24th. Every bug that is closed will be registered in the calendar. So instead of taking something from the calendar, this special one will be filled and at Christmas hopefully every Debian Med related bug is closed. Don t hestitate, start to squash

What happened in the reproducible builds effort this week: Toolchain fixes Dmitry Shachnev uploaded sphinx/1.3.1-6 with improved patches from Val Lorentz. Chris Lamb submitted a patch for ibus-table which makes the output of ibus-table-createdb deterministic. Niko Tyni wrote a patch to make libmodule-build-perl linking order deterministic. Santiago Vila has been leading discussions on the best way to fix timestamps coming from Gettext POT files. Packages fixed The following 35 packages became reproducible due to changes in their build dependencies: apache-log4j2, dctrl-tools, dms, gitit, gnubik, isrcsubmit, mailutils, normaliz, oaklisp, octave-fpl, octave-specfun, octave-vrml, opencolorio, openvdb, pescetti, php-guzzlehttp, proofgeneral, pyblosxom, pyopencl, pyqi, python-expyriment, python-flask-httpauth, python-mzml, python-simpy, python-tidylib, reactive-streams, scmxx, shared-mime-info, sikuli, siproxd, srtp, tachyon, tcltk-defaults, urjtag, velvet.

reproducible.debian.net Some bugs that prevented packages to build successfully in the remote builders have been fixed. (h01ger) Two more amd64 build jobs have been removed from the Jenkins host in favor of six more on the new remote nodes. (h01ger) The munin graphs currently looks fine, so more amd64 jobs will probably be added in the next week. diffoscope development Version 32 of diffoscope has been released on September 3rd with the following new features:

A new --fuzzy-threshold option to specify the TLSH score used as cut-off for fuzzy matching. Specifying 0 will disable fuzzy-matching entirely. Suggested by Jakub Wilk.
A new --new-file option to treat absent files as empty. This make diffoscope a great tool to look at the content of an archive at once by comparing it with a non-existent file (example). Suggested by Jakub Wilk.
Comparisons of symlinks and devices given on the command line is now possible.
Default values are displayed in --help.

It also fixes many bugs. Head over to the changelog for the full list. Version 33 was released the day after to fix a bug introduced in the packaging. Documentation update Chris Lamb blessed the SOURCE_DATE_EPOCH specification with the version number 1.0 . Lunar documented how the .file assembler directive can help with random filenames in debug symbols. Package reviews 235 reviews have been removed, 84 added and 277 updated this week. 29 new FTBFS bugs were filled by Chris Lamb, Chris West (Faux), Daniel Stender, and Niko Tyni. New issues identified this week: random_order_in_ibus_table_createdb_output, random_order_in_antlr_output, nondetermistic_link_order_in_module_build, and timestamps_in_tex_documents. Misc. Thanks to Dhole and Thomas Vincent, the talk held at DebConf15 now has subtitles! Void Linux started to merge changes to make packages produced by xbps reproducible.

I recently acquired a Lenovo Yoga 2 13. While, at the time, the Yoga 3 was available, I decided to go for Yoga 2 13. The Yoga 3 comes with the newer Core M Broadwell family, which, in my opinion, doesn't really bring any astounding benefits. The Yoga 2 13 comes in mulitple variants worldwide. Infact these hardware variations have different effets when run under Linux. My varaint of Yoga 2 13 is:

In the interim, to overcome this problem, we can force the device to run in degraded mode. I'm not sure if it is really the degraded mode, or the device was falsely advertised as a 6 GiB capable device. Time will tell, but for now, force it to run in 3 GiB mode, and so far, I haven't run into the above mentioned probems. To force 3 GiB speed, apply the following.

And then verify it... As you can see below, I've forced it for ata1 because I want my SSD drive to run at full-speed. I've done enough I/O, which earlier resulted in the kernel spitting the SATA errors. With this workaround, the kernel does not spit any error messages.

And the throughput you get out of your WD SATA SSHD drive, with capability set to 3.0 GiB is:

Hannes Reinecke has submitted patches for NCQ enhancements, for Linux 4.1, which I hope will resolve these problems. Another option is to disable NCQ for the drive, or else blacklist the make/model in driver/ata/libata-core.c

By the time I finished this blog entry draft, I had tests to conclude that this did not look like an NCQ problem. Because in degraded mode too, it runs with NCQ enabled (check above).

rrs@learner:~$ sudo fstrim -vv /media/SSHD
/media/SSHD: 268.2 GiB (287930949632 bytes) trimmed

Another interesting feature of this drive is support for TRIM / DISCARD. This drive's FTL accepts the TRIM command. Ofcourse, you need to ensure that you have discard enabled in all the layers. In my case, SATA + Device Mapper (Crypt and LVM) + File System (ext4) Display

The overall display of this device is amazing. It is large enough to give you vibrant look. At 1920x1080 resolution, things look good. The display support was available out-of-the-box.

There were some suspend / resume hangs that occured with kernels < 4.x, during suspend / resume. The issue was root caused and fixed for Linux 4.0.

You may still notice the following kernel messages, though not problematic to me so far.

You may need to disable the Intel Management Engine Interface (mei.ko), incase you run into suspend/resume problems.

rrs@learner:/media/SSHD/tmp$ cat /etc/modprobe.d/intel-mei-blacklist.conf
blacklist mei
blacklist mei-me

You may also run into the following Kernel Oops during suspend/resume. Below, you see 2 interation of sleep because it first hibernates and then sleeps (s2both).

Network

In my case, the laptop came with the Realtek Wireless device (details above in lspci output). Note: The machine has no wired interface.

While the Intel Wifi devices shipped with this laptop have their own share of problems, this device (rtl8723be) works out of the box. But only for a while. There is no certain pattern on what triggers the bug, but once triggered, the network just freezes. Nothing is logged.

If your Yoga 2 13 came with the RTL chip, the following workaround may help avoid the network issues.

rrs@learner:/media/SSHD/tmp$ cat /etc/modprobe.d/rtl8723be.conf
options rtl8723be fwlps=0

MCE

Almost every boot, eventually, the kernel reports MCE errors. Not something I understand well, but so far, it hasn't caused any visible issues. And from what I have googled so far, nobody seems to have fixed it anywhere

So, with fingers crossed, lets just hope this never translates into a real problem.

What the kernel reports of the CPU's capabilities.

Aftenposten, one of the largest newspapers in Norway, today report that three of the nude body scanners now is put to use at Gardermoen, the main airport in Norway. This way the travelers can have their body photographed without cloths when visiting Norway. Of course this horrible news is presented with a positive spin, stating that "now travelers can move past the security check point faster and more efficiently", but fail to mention that the machines in question take pictures of their nude bodies and store them internally in the computer, while only presenting sketch figure of the body to the public. The article is written in a way that leave the impression that the new machines do not take these nude pictures and only create the sketch figures. In reality the same nude pictures are still taken, but not presented to everyone. They are still available for the owners of the system and the people doing maintenance of the scanners, as long as they are taken and stored. Wikipedia have a more on Full body scanners, including example images and a summary of the controversy about these scanners. Personally I will decline to use these machines, as I believe strip searches of my body is a very intrusive attack on my privacy, and not something everyone should have to accept to travel.

Conclusion: Sound over HDMI works with the Sapphire Radeon HD 6450 card in my HP N54L microserver. It requires a recent kernel and firmware from Wheezy 7.7 backports and the X.org server. There is no sound without X.org, even if audio has been enabled for the radeon kernel module. Last year I couldn't get audio over HDMI to work after I installed a Sapphire Radeon HD 6450 1 GB (11190-02-20g) card into my N54L microserver. The cable that connects the HDMI interfaces between the card and the TV monitor supports HDMI 1.3, so audio should have been possible even then. However, I didn't get any audio output by XBMC playing video or music files. Nothing happened with stock Wheezy 7.1 and X.org/XBMC installed. So I removed the latter two and used the server as stock server without X/desktop and delayed my plans for an HTPC.Now I tried again after I found some new hints, that made me curious for a second try :) Imagine my joy, when (finally) speaker-test produced noise on the TV! So here is my configuration and a step-by-step guide to

enable Sound over HDMI for the Radeon HD 6450
install a graphical environment
install XBMC
automatically start XBMC on boot

The latter two will be covered by a second post. Also note, that there is lot of information out there to achive the above tasks. So this is only about my configuration. Some packages below are marked as optional. A few are necessary only for the N54L microserver (firmware) and for a few I'm not sure they are necessary at all. Step 1 - Prepare the systemAt this point I don't have any desktop nor any other graphical environment (X.org) installed. First I purged pulseaudio and related packages completely and only use ALSA:

# apt-get autoremove --purge pulseaudio pulseaudio-utils pulseaudio-module-x11 gstreamer0.10-pulseaudio
# apt-get install alsa-base alsa-utils alsa-oss

Next I installed a recent linux kernel and recent firmware from Wheezy backports:

# apt-get install -t wheezy-backports linux-image-amd64 firmware-linux-free firmware-linux firmware-linux-nonfree firmware-atheros firmware-bnx2 firmware-bnx2x

This put linux-image-3.16-0.bpo.3-amd64 and recent firmware onto my system. I've chosen to upgrade linux-image-amd64 instead to pick a special (recent) linux kernel package from Wheezy backports to keep up-to-date with recent kernels from there.Then I enabled the audio output of the kernel radeon module. Essentially there are at least three ways to do this. I use the one to modify /etc/modules.d/radeon.conf and set the audio parameter there. The hw_i2c parameter is disabled. I read, that it might cause trouble with the audio output here although I never personally experienced it:

options radeon audio=1 hw_i2c=0

JFTR: This is how I boot the N54L by default:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force pcie_aspm=force nmi_watchdog=0"

After rebooting I see this for the Radeon card in question:

    HDMI Audio Output

At this point, without having the X.org server installed, I still have no audio output to the connected monitor. Running alsamixer I only see the S/PDIF bar for the HDA ATI HDMI device, showing a value of 00. I can mute and un-mute this device but not change the value. No need to worry, sound comes with step two. Step 2 - Install a graphical environment (X.org server)Next is to install a graphical environment, basically the X.org server. This is done in Debian by the desktop task. Unfortunately tasksel makes use of APT::Install-Recommends="true" and would install a desktop environment and some more recommended packages. At the moment I don't want this, only X. So basically I installed only the task-desktop package with dependencies:

# apt-get install task-desktop xfonts-cyrillic

Next is to install a display manager. I've chosen lightdm:

# apt-get install lightdm accountsservice

Done. Now (re-)start the X server. Simply ...

# service lightdm restart

... should do. And now there is sound, probably due to the X.org Radeon driver. The following command created noise on the two monitor speakers :)

# speaker-test -c2 -D hdmi:0 -t pink

Finally there is sound over HDMI! Step 3 - Install XBMC To be continued ...

I started transitioning from 1024D to 4096R. The new key is available at: https://people.debian.org/~jak/pubkey.gpg and the keys.gnupg.net key server. A very short transition statement is available at: https://people.debian.org/~jak/transition-statement.txt and included below (the http version might get extended over time if needed). The key consists of one master key and 3 sub keys (signing, encryption, authentication). The sub keys are stored on an OpenPGP v2 Smartcard. That s really cool, isn t it? Somehow it seems that GnuPG 1.4.18 also works with 4096R keys on this smartcard (I accidentally used it instead of gpg2 and it worked fine), although only GPG 2.0.13 and newer is supposed to work.

Oh, time flies... (= I'm lazy)

14th June, I've participated to OSC (Open Source Conference) 2014 Hokkaido in Sapporo, Hokkaido (sorry openSUSE folks, OSC does not mean openSUSE Conference ;) OSC has 10 years history in Japan, so don't blame me...)

Hokkaido is northan island of Japan (it has 4 major islands - Hokkaido, Honshu, Shikoku and Kyushu), takes 1.5 hours from Tokyo (HND-CTS) and debian-mirror.sakura.ne.jp is also there.

As always, we show the Debian booth with Debian lovers, Squeeze, Woody and Jessie.

And I gave talk about Debian a little,

mostly how it is developed and distribute, and shapes in Jessie at that time (PDF/odf is my page on Debian Wiki as usual).

Does Cowgirl Dream of Red Swirl? from Hideki Yamane

After that, Enjoyed food, beer (sure! :) and chatting in party.

Folks, see you in #osc15do again!

Wow. 3G delta. I haven t booted this laptop for a while I think I m finally ready to make the move from gnome2 to gnome3. There are bits that still annoy me, but I think it s off to a good start. Upgrading perl from 5.10 to 5.14.
