Reproducible builds folks: Reproducible Builds: Weekly report #133

Here's what happened in the Reproducible Builds effort between Sunday November 5 and Saturday November 11 2017: Upcoming events On November 17th Chris Lamb will present at Open Compliance Summit, Yokohama, Japan on how reproducible builds ensures the long-term sustainability of technology infrastructure. We plan to hold an assembly at 34C3 - hope to see you there! LEDE CI tests Thanks to the work of lynxis, Mattia and h01ger, we're now testing all LEDE packages in our setup. This is our first result for the ar71xx target: "502 (100.0%) out of 502 built images and 4932 (94.8%) out of 5200 built packages were reproducible in our test setup." - see below for details how this was achieved. Bootstrapping and Diverse Double Compilation As a follow-up of a discussion on bootstrapping compilers we had on the Berlin summit, Bernhard and Ximin worked on a Proof of Concept for Diverse Double Compilation of tinycc (aka tcc). Ximin Luo did a successful diverse-double compilation of tinycc git HEAD using gcc-7.2.0, clang-4.0.1, icc-18.0.0 and pgcc-17.10-0 (pgcc needs to triple-compile it). More variations are planned for the future, with the eventual aim to reproduce the same binaries cross-distro, and extend it to test GCC itself.

Here's what happened in the Reproducible Builds effort between Sunday October 22 and Saturday October 28 2017: Past Events Upcoming/current events Documentation updates Bernhard Wiedemann started The Unreproducible Package which "is meant as a practical way to demonstrate the various ways that software can break reproducible builds using just low level primitives without requiring external existing programs that implement these primitives themselves. It is structured so that one subdirectory demonstrates one class of issues in some variants observed in the wild." Reproducible work in other projects Hush, a fork of ZCash, opened an issue into reproducible builds. A new tag was added to lintian (lint checker for Debian packages) to ensure that changelog entry timestamps are strictly increasing. This avoids certain real-world issues with identical timestamps, documented in Debian #843773.

Holger Levsen: 20171024-Reproducible-Builds-Summit-3

Reproducible Builds Summit 3 next week in Berlin Next week from Tuesday, the 31st of October until Thursday, November 2nd, we'll have the 3rd Reproducible Builds summit in Berlin, to improve collaboration both between and inside projects, expand the scope and reach of reproducible builds to more projects and to brainstorm designs on tools enabling users to get the most benefits from reproducible builds. We're again expecting contributors from around twenty projects and we're still having some free seats available. If you want to join this meeting, please register by sending us a short mail briefly describing why (eg. by stating you involvement in some project). We also have some funding available to further rextend the diversity of our community, so please also contact us if you think you cannot make it for financial reasons! Personally I'm much looking forward to this event. The reproducible builds crowd is really a lovely bunch of people and thus I expect us to have some great discussions, some cool ideas and also some concrete actionable plans as a result of it. Totally worth it! Talk about Reproducible Builds at OSSE in Prague tomorrow Tomorrow, Wednesday, October 25th I'll be giving a talk at OSSE in Prague about the current status of Reproducible Builds and why we are not 'there' yet. I'd be glad to have a chat with you if you are there!

Chris Lamb: Free software activities in August 2017

Here is my monthly update covering what I have been doing in the free software world in August 2017 (previous month):
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:
  • 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)

Holger Levsen: 20170829-qubes-os

"Qubes OS from the POV of a Debian developer" and "Qubes OS user meetup at Bornhack" I wrote the following while on my way home from Bornhack which was an awesome hacking camp on the Danish island of Bornholm, where about 200 people gathered for a week, with a nice beach in walking distance (and a not too cold Baltic Sea) and vegan and not so vegan grills, to give some hints why it was awesome. (Actually it was mostly awesome due to the people there, not the things, but anyway ) And there were of course also talks and workshops, and one was a Qubes OS users meetup, which amazingly was attended by 20 Qubes OS users (and some Qubes OS users present were even missing), so in other words: Qubes OS had a >10% user base at this event! And I even found one heads user! ;-) At DebConf17 I gave a talk titled "Qubes OS from the POV of a Debian developer" and while the video was immediatly available (thanks to the DebConf videoteam!) I've also now put my slides for it online. Since then, I learned a few things: I'm looking forward to more Qubes OS user meetups in future!

Holger Levsen: 20170827-coreboot-build-environment

setting up a coreboot build environment, including an Ada compiler So without much explaination, this is how lynxis told me how to setup a coreboot build environment, which contains an Ada compiler which is needed to build the free graphics initialisation for Intel cards (=so no binary VGA bios blob is needed). The Ada compiler is build automatically by default if it's build depends are installed:
sudo apt install build-essential bison flex zlib1g-dev ncurses-dev gnat
git clone --recursive https://review.coreboot.org/p/coreboot.git
cd coreboot/
git submodule update --init --checkout 3rdparty/blobs   # for the x230 this only contains microcode updates
make iasl CPUS=$(nproc)
make gnumake CPUS=$(nproc)
make crossgcc-i386 CPUS=$(nproc)
coreboot is then build as usual:
make menuconfig
make
That's it. (I've just left out the steps to choose the coreboot revision and validating it, as well as choosing a configurationwith make menuconfig as this is better documented elsewhere.)

Reproducible builds folks: Reproducible Builds: Weekly report #121

Here's what happened in the Reproducible Builds effort between Sunday August 13 and Saturday August 19 2017: Reproducible Builds finally mandated by Debian Policy "Packages should build reproducibly" was merged into Debian policy! The added text is as follows and has been included into debian-policy 4.1.0.0:
Reproducibility
---------------
Packages should build reproducibly, which for the purposes of this
document [#]_ means that given
- a version of a source package unpacked at a given path;
- a set of versions of installed build dependencies;
- a set of environment variable values;
- a build architecture; and
- a host architecture,
repeatedly building the source package for the build architecture on
any machine of the host architecture with those versions of the build
dependencies installed and exactly those environment variable values
set will produce bit-for-bit identical binary packages.
It is recommended that packages produce bit-for-bit identical binaries
even if most environment variables and build paths are varied.  It is
intended for this stricter standard to replace the above when it is
easier for packages to meet it.
.. [#]
   This is Debian's precisification of the  reproducible-builds.org
   definition  _.
Reproducible work in other projects Bernhard M. Wiedemann's reproducibleopensuse scripts now work on Debian buster on the openSUSE Build Service with the latest versions of osc and obs-build. Toolchain development and fixes #872514 was opened on devscripts by Chris Lamb to add a reproducible-check program to report on the reproducibility status of installed packages. Packages reviewed and fixed, and bugs filed Upstream reports: Debian reports: Debian non-maintainer uploads: Reviews of unreproducible packages 47 package reviews have been added, 58 have been updated and 39 have been removed in this week, adding to our knowledge about identified issues. 4 issue types have been updated: Weekly QA work During our reproducibility testing, FTBFS bugs have been detected and reported by: diffoscope development Development continued in git, including the following contributions: disorderfs development Development continued in git, including the following contributions: reprotest development Development continued in git, including the following contributions: tests.reproducible-builds.org Mattia fixed the script which creates the HTML representation of our database scheme to not append .html twice to the filename.

laser-cutter sprint So I'm overcoming my jetlag after DebConf17 by helping to make the Alioth sprint happen, and while it's good to witness work on the upcoming git.debian.org replacement, I'm rather minding my own business instead of getting involved And so I got interested in this laser cutter, which since two months has been set up in the CCCHH hackerspace and which is nicely documentend (and set up), so I managed to learn how to do my first baby steps with the laser cutter in one evening: Basically there is a hosted web application named 'LaserWeb4' for which a pre-configuration exists, so that one only needs to load an image, scale and position it and tune the laser settings a bit. The laser itself is inside a cage, which has a physical safety switch which will turn off the laser if the cage is opened. Obviously the setup is a lot more complex and there are many parameters to tune, and I basically just learned one thing, which is "printing images on wood", but "printing images on a laptop cover" should be pretty similar and something to learn in the future ;-) And now I'm even teaching weasel how to use this thing (and he already made interesting new mistakes) and it looks like Ganneff & formorer are next. Fun fun fun! Oh, and the Alioth sprint also seems to be quite productive, but I'll leave reporting about this to others.
