Arch Linux minimal container userland now 100% reproducible In remarkable news, Reproducible builds developer kpcyrd reported that that the Arch Linux minimal container userland is now 100% reproducible after work by developers dvzv and Foxboron on the one remaining package. This represents a real world , widely-used Linux distribution being reproducible. Their post, which kpcyrd suffixed with the question now what? , continues on to outline some potential next steps, including validating whether the container image itself could be reproduced bit-for-bit. The post, which was itself a followup for an Arch Linux update earlier in the month, generated a significant number of replies.

Validating Debian s build infrastructure after the XZ backdoor From our mailing list this month, Vagrant Cascadian wrote about being asked about trying to perform concrete reproducibility checks for recent Debian security updates, in an attempt to gain some confidence about Debian s build infrastructure given that they performed builds in environments running the high-profile XZ vulnerability. Vagrant reports (with some caveats):

So far, I have not found any reproducibility issues; everything I tested I was able to get to build bit-for-bit identical with what is in the Debian archive.

That is to say, reproducibility testing permitted Vagrant and Debian to claim with some confidence that builds performed when this vulnerable version of XZ was installed were not interfered with.

Making Fedora Linux (more) reproducible In March, Davide Cavalca gave a talk at the 2024 Southern California Linux Expo (aka SCALE 21x) about the ongoing effort to make the Fedora Linux distribution reproducible. Documented in more detail on Fedora s website, the talk touched on topics such as the specifics of implementing reproducible builds in Fedora, the challenges encountered, the current status and what s coming next. (YouTube video)

Increasing Trust in the Open Source Supply Chain with Reproducible Builds and Functional Package Management Julien Malka published a brief but interesting paper in the HAL open archive on Increasing Trust in the Open Source Supply Chain with Reproducible Builds and Functional Package Management:

Functional package managers (FPMs) and reproducible builds (R-B) are technologies and methodologies that are conceptually very different from the traditional software deployment model, and that have promising properties for software supply chain security. This thesis aims to evaluate the impact of FPMs and R-B on the security of the software supply chain and propose improvements to the FPM model to further improve trust in the open source supply chain. PDF

Julien s paper poses a number of research questions on how the model of distributions such as GNU Guix and NixOS can be leveraged to further improve the safety of the software supply chain , etc.

Software and source code identification with GNU Guix and reproducible builds In a long line of commendably detailed blog posts, Ludovic Court s, Maxim Cournoyer, Jan Nieuwenhuizen and Simon Tournier have together published two interesting posts on the GNU Guix blog this month. In early March, Ludovic Court s, Maxim Cournoyer, Jan Nieuwenhuizen and Simon Tournier wrote about software and source code identification and how that might be performed using Guix, rhetorically posing the questions: What does it take to identify software ? How can we tell what software is running on a machine to determine, for example, what security vulnerabilities might affect it? Later in the month, Ludovic Court s wrote a solo post describing adventures on the quest for long-term reproducible deployment. Ludovic s post touches on GNU Guix s aim to support time travel , the ability to reliably (and reproducibly) revert to an earlier point in time, employing the iconic image of Harold Lloyd hanging off the clock in Safety Last! (1925) to poetically illustrate both the slapstick nature of current modern technology and the gymnastics required to navigate hazards of our own making.

Two new Rust-based tools for post-processing determinism Zbigniew J drzejewski-Szmek announced add-determinism, a work-in-progress reimplementation of the Reproducible Builds project s own strip-nondeterminism tool in the Rust programming language, intended to be used as a post-processor in RPM-based distributions such as Fedora In addition, Yossi Kreinin published a blog post titled refix: fast, debuggable, reproducible builds that describes a tool that post-processes binaries in such a way that they are still debuggable with gdb, etc.. Yossi post details the motivation and techniques behind the (fast) performance of the tool.

Distribution work In Debian this month, since the testing framework no longer varies the build path, James Addison performed a bulk downgrade of the bug severity for issues filed with a level of normal to a new level of wishlist. In addition, 28 reviews of Debian packages were added, 38 were updated and 23 were removed this month adding to ever-growing knowledge about identified issues. As part of this effort, a number of issue types were updated, including Chris Lamb adding a new ocaml_include_directories toolchain issue [ ] and James Addison adding a new filesystem_order_in_java_jar_manifest_mf_include_resource issue [ ] and updating the random_uuid_in_notebooks_generated_by_nbsphinx to reference a relevant discussion thread [ ]. In addition, Roland Clobus posted his 24th status update of reproducible Debian ISO images. Roland highlights that the images for Debian unstable often cannot be generated due to changes in that distribution related to the 64-bit time_t transition. Lastly, Bernhard M. Wiedemann posted another monthly update for his reproducibility work in openSUSE.

Mailing list highlights Elsewhere on our mailing list this month:

• Alexander Railean of Siemens asked the list to aid in understanding how one can independently verify the reproducibility of Java projects from the Maven Central repository. Having explored those repositories, Alexander could not find examples where the buildinfo file was present. Arnout Engelen responded with some details.
• Fay Stegerman resuscitated a long-dormant thread to report that she added support in her diff-zip-meta.py tool to expose extra timestamps embedded in .zip and .apk metadata.

Website updates There were made a number of improvements to our website this month, including:

• Pol Dellaiera noticed the frequent need to correctly cite the website itself in academic work. To facilitate easier citation across multiple formats, Pol contributed a Citation File Format (CIF) file. As a result, an export in BibTeX format is now available in the Academic Publications section. Pol encourages community contributions to further refine the CITATION.cff file. Pol also added an substantial new section to the buy in page documenting the role of Software Bill of Materials (SBOMs) and ephemeral development environments. [ ][ ]
• Bernhard M. Wiedemann added a new commandments page to the documentation [ ][ ] and fixed some incorrect YAML elsewhere on the site [ ].
• Chris Lamb add three recent academic papers to the publications page of the website. [ ]
• Mattia Rizzolo and Holger Levsen collaborated to add Infomaniak as a sponsor of amd64 virtual machines. [ ][ ][ ]
• Roland Clobus updated the stable outputs page, dropping version numbers from Python documentation pages [ ] and noting that Python s set data structure is also affected by the PYTHONHASHSEED functionality. [ ]

Delta chat clients now reproducible Delta Chat, an open source messaging application that can work over email, announced this month that the Rust-based core library underlying Delta chat application is now reproducible.

diffoscope diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues. This month, Chris Lamb made a number of changes such as uploading versions 259, 260 and 261 to Debian and made the following additional changes:

• New features:
  • Add support for the zipdetails tool from the Perl distribution. Thanks to Fay Stegerman and Larry Doolittle et al. for the pointer and thread about this tool. [ ]
• Bug fixes:
  • Don t identify Redis database dumps as GNU R database files based simply on their filename. [ ]
  • Add a missing call to File.recognizes so we actually perform the filename check for GNU R data files. [ ]
  • Don t crash if we encounter an .rdb file without an equivalent .rdx file. (#1066991)
  • Correctly check for 7z being available and not lz4 when testing 7z. [ ]
  • Prevent a traceback when comparing a contentful .pyc file with an empty one. [ ]
• Testsuite improvements:
  • Fix .epub tests after supporting the new zipdetails tool. [ ]
  • Don t use parenthesis within test skipping messages, as PyTest adds its own parenthesis. [ ]
  • Factor out Python version checking in test_zip.py. [ ]
  • Skip some Zip-related tests under Python 3.10.14, as a potential regression may have been backported to the 3.10.x series. [ ]
  • Actually test 7z support in the test_7z set of tests, not the lz4 functionality. (Closes: reproducible-builds/diffoscope#359). [ ]

In addition, Fay Stegerman updated diffoscope s monkey patch for supporting the unusual Mozilla ZIP file format after Python s zipfile module changed to detect potentially insecure overlapping entries within .zip files. (#362) Chris Lamb also updated the trydiffoscope command line client, dropping a build-dependency on the deprecated python3-distutils package to fix Debian bug #1065988 [ ], taking a moment to also refresh the packaging to the latest Debian standards [ ]. Finally, Vagrant Cascadian submitted an update for diffoscope version 260 in GNU Guix. [ ]

Bernhard M. Wiedemann used reproducibility-tooling to detect and fix packages that added changes in their %check section, thus failing when built with the --no-checks option. Only half of all openSUSE packages were tested so far, but a large number of bugs were filed, including ones against caddy, exiv2, gnome-disk-utility, grisbi, gsl, itinerary, kosmindoormap, libQuotient, med-tools, plasma6-disks, pspp, python-pypuppetdb, python-urlextract, rsync, vagrant-libvirt and xsimd. Similarly, Jean-Pierre De Jesus DIAZ employed reproducible builds techniques in order to test a proposed refactor of the ath9k-htc-firmware package. As the change produced bit-for-bit identical binaries to the previously shipped pre-built binaries:

I don t have the hardware to test this firmware, but the build produces the same hashes for the firmware so it s safe to say that the firmware should keep working.

Reproducibility testing framework The Reproducible Builds project operates a comprehensive testing framework running primarily at tests.reproducible-builds.org in order to check packages and other artifacts for reproducibility. In March, an enormous number of changes were made by Holger Levsen:

• Debian-related changes:
  • Sleep less after a so-called 404 package state has occurred. [ ]
  • Schedule package builds more often. [ ][ ]
  • Regenerate all our HTML indexes every hour, but only every 12h for the released suites. [ ]
  • Create and update unstable and experimental base systems on armhf again. [ ][ ]
  • Don t reschedule so many depwait packages due to the current size of the i386 architecture queue. [ ]
  • Redefine our scheduling thresholds and amounts. [ ]
  • Schedule untested packages with a higher priority, otherwise slow architectures cannot keep up with the experimental distribution growing. [ ]
  • Only create the stats_buildinfo.png graph once per day. [ ][ ]
  • Reproducible Debian dashboard: refactoring, update several more static stats only every 12h. [ ]
  • Document how to use systemctl with new systemd-based services. [ ]
  • Temporarily disable armhf and i386 continuous integration tests in order to get some stability back. [ ]
  • Use the deb.debian.org CDN everywhere. [ ]

  • Show failed services that require manual cleanup. [ ][ ]
  • Integrate two new Infomaniak nodes. [ ][ ][ ][ ]
  • Improve IRC notifications for artifacts. [ ]
  • Run diffoscope in different systemd slices. [ ]
  • Run the node health check more often, as it can now repair some issues. [ ][ ]
  • Also include the string Bot in the userAgent for Git. (Re: #929013). [ ]
  • Document increased tmpfs size on our OUSL nodes. [ ]
  • Disable memory account for the reproducible_build service. [ ][ ]
  • Allow 10 times as many open files for the Jenkins service. [ ]
  • Set OOMPolicy=continue and OOMScoreAdjust=-1000 for both the Jenkins and the reproducible_build service. [ ]

Mattia Rizzolo also made the following changes:

• Debian-related changes:
  • Define a systemd slice to group all relevant services. [ ][ ]
  • Add a bunch of quotes in scripts to assuage the shellcheck tool. [ ]
  • Add stats on how many packages have been built today so far. [ ]
  • Instruct systemd-run to handle diffoscope s exit codes specially. [ ]
  • Prefer the pgrep tool over grepping the output of ps. [ ]
  • Re-enable a couple of i386 and armhf architecture builders. [ ][ ]
  • Fix some stylistic issues flagged by the Python flake8 tool. [ ]
  • Cease scheduling Debian unstable and experimental on the armhf architecture due to the time_t transition. [ ]
  • Start a few more i386 & armhf workers. [ ][ ][ ]
  • Temporarly skip pbuilder updates in the unstable distribution, but only on the armhf architecture. [ ]
• Other changes:
  • Perform some large-scale refactoring on how the systemd service operates. [ ][ ]
  • Move the list of workers into a separate file so it s accessible to a number of scripts. [ ]
  • Refactor the powercycle_x86_nodes.py script to use the new IONOS API and its new Python bindings. [ ]
  • Also fix nph-logwatch after the worker changes. [ ]
  • Do not install the stunnel tool anymore, it shouldn t be needed by anything anymore. [ ]
  • Move temporary directories related to Arch Linux into a single directory for clarity. [ ]
  • Update the arm64 architecture host keys. [ ]
  • Use a common Postfix configuration. [ ]

The following changes were also made by:

• Jan-Benedict Glaw:
  • Initial work to clean up a messy NetBSD-related script. [ ][ ]
• Roland Clobus:
  • Show the installer log if the installer fails to build. [ ]
  • Avoid the minus character (i.e. -) in a variable in order to allow for tags in openQA. [ ]
  • Update the schedule of Debian live image builds. [ ]
• Vagrant Cascadian:
  • Maintenance on the virt* nodes is completed so bring them back online. [ ]
  • Use the fully qualified domain name in configuration. [ ]

Node maintenance was also performed by Holger Levsen, Mattia Rizzolo [ ][ ] and Vagrant Cascadian [ ][ ][ ][ ]

• Andreas Tille [this document]
• Sruthi Chandran [Interview]

How am I? Well, I'm, as I wrote in my platform, I'm a proud grandfather doing a lot of free software stuff, doing a lot of sports, have some goals in mind which I like to do and hopefully for the best of Debian.

How I'm doing today? Well, actually I have some headaches but it's fine for the interview. So, usually I feel very good. Spring was coming here and today it's raining and I plan to do a bicycle tour tomorrow and hope that I do not get really sick but yeah, for the interview it's fine.

Yeah, well, I started with Debian kind of an accident because I wanted to have some package salvaged which is called WordNet. It's a monolingual dictionary and I did not really plan to do more than maybe 10 packages or so. I had some kind of training with xTeddy which is totally unimportant, a cute teddy you can put on your desktop. So, and then well, more or less I thought how can I make Debian attractive for my employer which is a medical institute and so on. It could make sense to package bioinformatics and medicine software and it somehow evolved in a direction I did neither expect it nor wanted to do, that I'm currently the most busy uploader in Debian, created several teams around it. DebianMate is very well known from me. I created the Blends team to create teams and techniques around what we are doing which was Debian TIS, Debian Edu, Debian Science and so on and I also created the packaging team for R, for the statistics package R which is technically based and not topic based. All these blends are covering a certain topic and R is just needed by lots of these blends. So, yeah, and to cope with all this I have written a script which is routing an update to manage all these uploads more or less automatically. So, I think I had one day where I uploaded 21 new packages but it's just automatically generated, right? So, it's on one day more than I ever planned to do.

The worst thing I think about Debian, it's complicated. I think today on Debian board I was asked about the technical progress I want to make and in my opinion we need to standardize things inside Debian. For instance, bringing all the packages to salsa, follow some common standards, some common workflow which is extremely helpful. As I said, if I'm that productive with my own packages we can adopt this in general, at least in most cases I think. I made a lot of good experience by the support of well-formed teams. Well-formed teams are those teams where people support each other, help each other. For instance, how to say, I'm a physicist by profession so I'm not an IT expert. I can tell apart what works and what not but I'm not an expert in those packages. I do and the amount of packages is so high that I do not even understand all the techniques they are covering like Go, Rust and something like this. And I also don't speak Java and I had a problem once in the middle of the night and I've sent the email to the list and was a Java problem and I woke up in the morning and it was solved. This is what I call a team. I don't call a team some common repository that is used by random people for different packages also but it's working together, don't hesitate to solve other people's problems and permit people to get active. This is what I call a team and this is also something I observed in, it's hard to give a percentage, in a lot of other teams but we have other people who do not even understand the concept of the team. Why is working together make some advantage and this is also a tough thing. I [would] like to tackle in my term if I get elected to form solid teams using the common workflow. This is one thing. The other thing is that we have a lot of good people in our infrastructure like FTP masters, DSA and so on. I have the feeling they have a lot of work and are working more or less on their limits, and I like to talk to them [to ask] what kind of change we could do to move that limits or move their personal health to the better side.

Yeah, well this is basically what I said are my main issues. I need to admit I have no really clear imagination what kind of tasks will come to me as a DPL because all these financial issues and law issues possible and issues [that] people who are not really friendly to Debian might create. I'm afraid these things might occupy a lot of time and I can't say much about this because I simply don't know.

As I said, I like to work on standards, I d like to make Debian try [to get it right so] that people don't get overworked, this third key point is be inviting to newcomers, to everybody who wants to come. Yeah, I also mentioned in my term this diversity issue, geographical and from gender point of view. This may be the three points I consider most important.

Yeah, my preferred one? Ah, well, I have no preferred text editor. I'm using the Midnight Commander very frequently which has an internal editor which is convenient for small text. For other things, I usually use VI but I also use Emacs from time to time. So, no, I have not preferred text editor. Whatever works nicely for me.

Yeah, I think the community is extremely important. So, I was on a lot of DebConfs. I think it's not really 20 but 17 or 18 DebCons and I really enjoyed these events every year because I met so many friends and met so many interesting people that it's really enriching my life and those who I never met in person but have read interesting things and yeah, Debian community makes really a part of my life.

Yeah, for instance, last year in Kochi, it became even clearer to me that the geographical diversity is a really strong point. Just discussing with some women from India who is afraid about not coming next year to Busan because there's a problem with Shanghai and so on. I'm not really sure how we can solve this but I think this is a problem at least I wish to tackle and yeah, this is an interesting point, the geographical diversity and I'm running the so-called mentoring of the month. This is a small project to attract newcomers for the Debian Med team which has the focus on medical packages and I learned that we had always men applying for this and so I said, okay, I dropped the constraint of medical packages. Any topic is fine, I teach you packaging but it must be someone who does not consider himself a man. I got only two applicants, no, actually, I got one applicant and one response which was kind of strange if I'm hunting for women or so. I did not understand but I got one response and interestingly, it was for me one of the least expected counters. It was from Iran and I met a very nice woman, very open, very skilled and gifted and did a good job or have even lose contact today and maybe we need more actively approach groups that are underrepresented. I don't know if what's a good means which I did but at least I tried and so I try to think about these kind of things.

Well, the card game which is called Mao on the DebConf made me smile all the time. I admit I joined only two or three times even if I really love this kind of games but I was occupied by other stuff so this made me really smile. I also think the first online DebConf in 2020 made me smile because we had this kind of short video sequences and I tried to make a funny video sequence about every DebConf I attended before. This is really funny moments but yeah, it's not only smile but yeah. One thing maybe it's totally unconnected to Debian but I learned personally something in Debian that we have a do-ocracy and you can do things which you think that are right if not going in between someone else, right? So respect everybody else but otherwise you can do so. And in 2020 I also started to take trees which are growing widely in my garden and plant them into the woods because in our woods a lot of trees are dying and so I just do something because I can. I have the resource to do something, take the small tree and bring it into the woods because it does not harm anybody. I asked the forester if it is okay, yes, yes, okay. So everybody can do so but I think the idea to do something like this came also because of the free software idea. You have the resources, you have the computer, you can do something and you do something productive, right? And when thinking about this I think it was also my Debian work. Meanwhile I have planted more than 3,000 trees so it's not a small number but yeah, I enjoy this.

Yeah, it's basically the same as I said before. We need more standards to work together. I do not want to repeat this but this is what I think, yeah.

It's also in general, the thing is the fact that I'm maintaining packages which are usually as modern software is maintained in Git, which is fine but we have some software which is at Sourceport, we have software laying around somewhere, we have software where Debian somehow became Upstream because nobody is caring anymore and free software is very different in several things, ways and well, I in principle like freedom of choice which is the basic of all our work. Sometimes this freedom goes in the way of productivity because everybody is free to re-implement. You asked me for the most favorite editor. In principle one really good working editor would be great to have and would work and we have maybe 500 in Debian or so, I don't know. I could imagine if people would concentrate and say five instead of 500 editors, we could get more productive, right? But I know this will not happen, right? But I think this is one thing which goes in the way of making things smooth and productive and we could have more manpower to replace one person who's [having] children, doing some other stuff and can't continue working on something and maybe this is a problem I will not solve, definitely not, but which I see.

Yeah, well, okay, we can bring together different Upstreams, so we are building some packages and have some general overview about similar things and can say, oh, you are doing this and some other person is doing more or less the same, do you want to join each other or so, but this is kind of a channel we have to our Upstreams which is probably not very successful. It starts with code copies of some libraries which are changed a little bit, which is fine license-wise, but not so helpful for different things and so I've tried to convince those Upstreams to forward their patches to the original one, but for this and I think we could do some kind of, yeah, [find] someone who brings Upstream together or to make them stop their forking stuff, but it costs a lot of energy and we probably don't have this and it's also not realistic that we can really help with this problem.

I enjoyed the interview, I enjoyed seeing you again after half a year or so. Yeah, actually I've seen you in the eating room or cheese and wine party or so, I do not remember we had to really talk together, but yeah, people around, yeah, for sure. Yeah.

  • The Suggests: is a little tighter as we do not list all packages optionally used in the the examples (as R does not check for it either)
  • The package load messag can account for the rare build of R under different architecture (Berwin Turlach in #117 closing #116)
  • In non-vanilla mode, the temporary directory initialization in re-run allowing for a non-standard temp dir via config settings

Usage: ciw.r [-h] [-x] [-a] [-m] [-i] [-t] [-p] [-w] [-r] [-s] [-n] [-u] [-l rows] [-z] [ARG...]

-m --mega           use 'mega' mode of all folders (see --usage)
-i --inspect        visit 'inspect' folder
-t --pretest        visit 'pretest' folder
-p --pending        visit 'pending' folder
-w --waiting        visit 'waiting' folder
-r --recheck        visit 'waiting' folder
-a --archive        visit 'archive' folder
-n --newbies        visit 'newbies' folder
-u --publish        visit 'publish' folder
-s --skipsort       skip sorting of aggregate results by age
-l --lines rows     print top 'rows' of the result object [default: 50]
-z --ping           run the connectivity check first
-h --help           show this help text
-x --usage          show help and short example usage 

where ARG... can be one or more file name, or directories or package names.

Examples:
  ciw.r -ip                            # run in 'inspect' and 'pending' mode
  ciw.r -a                             # run with mode 'auto' resolved in incoming()
  ciw.r                                # run with defaults, same as '-itpwr'

When no argument is given, 'auto' is selected which corresponds to 'inspect', 'waiting',
'pending', 'pretest', and 'recheck'. Selecting '-m' or '--mega' are select as default.

Folder selecting arguments are cumulative; but 'mega' is a single selections of all folders
(i.e. 'inspect', 'waiting', 'pending', 'pretest', 'recheck', 'archive', 'newbies', 'publish').

ciw.r is part of littler which brings 'r' to the command-line.

Reproducible Builds at FOSDEM 2024 Core Reproducible Builds developer Holger Levsen presented at the main track at FOSDEM on Saturday 3rd February this year in Brussels, Belgium. However, that wasn t the only talk related to Reproducible Builds. However, please see our comprehensive FOSDEM 2024 news post for the full details and links.

Maintainer Perspectives on Open Source Software Security Bernhard M. Wiedemann spotted that a recent report entitled Maintainer Perspectives on Open Source Software Security written by Stephen Hendrick and Ashwin Ramaswami of the Linux Foundation sports an infographic which mentions that 56% of [polled] projects support reproducible builds .

Three new reproducibility-related academic papers A total of three separate scholarly papers related to Reproducible Builds have appeared this month: Signing in Four Public Software Package Registries: Quantity, Quality, and Influencing Factors by Taylor R. Schorlemmer, Kelechi G. Kalu, Luke Chigges, Kyung Myung Ko, Eman Abdul-Muhd, Abu Ishgair, Saurabh Bagchi, Santiago Torres-Arias and James C. Davis (Purdue University, Indiana, USA) is concerned with the problem that:

Package maintainers can guarantee package authorship through software signing [but] it is unclear how common this practice is, and whether the resulting signatures are created properly. Prior work has provided raw data on signing practices, but measured single platforms, did not consider time, and did not provide insight on factors that may influence signing. We lack a comprehensive, multi-platform understanding of signing adoption and relevant factors. This study addresses this gap. (arXiv, full PDF)

Reproducibility of Build Environments through Space and Time by Julien Malka, Stefano Zacchiroli and Th o Zimmermann (Institut Polytechnique de Paris, France) addresses:

[The] principle of reusability [ ] makes it harder to reproduce projects build environments, even though reproducibility of build environments is essential for collaboration, maintenance and component lifetime. In this work, we argue that functional package managers provide the tooling to make build environments reproducible in space and time, and we produce a preliminary evaluation to justify this claim.

The abstract continues with the claim that Using historical data, we show that we are able to reproduce build environments of about 7 million Nix packages, and to rebuild 99.94% of the 14 thousand packages from a 6-year-old Nixpkgs revision. (arXiv, full PDF)
Options Matter: Documenting and Fixing Non-Reproducible Builds in Highly-Configurable Systems by Georges Aaron Randrianaina, Djamel Eddine Khelladi, Olivier Zendra and Mathieu Acher (Inria centre at Rennes University, France):

This paper thus proposes an approach to automatically identify configuration options causing non-reproducibility of builds. It begins by building a set of builds in order to detect non-reproducible ones through binary comparison. We then develop automated techniques that combine statistical learning with symbolic reasoning to analyze over 20,000 configuration options. Our methods are designed to both detect options causing non-reproducibility, and remedy non-reproducible configurations, two tasks that are challenging and costly to perform manually. (HAL Portal, full PDF)

Mailing list highlights From our mailing list this month:

• User cen posted a query asking How to verify a package by rebuilding it locally on Debian which received a followup from Vagrant Cascadian.
• James Addison asked Two questions about build-path reproducibility in Debian regarding the differences in the testing performed by Debian s GitLab continuous integration (CI) pipeline and the Debian-specific testing performed by the Reproducible Builds project itself, and followed this with a separate but related question regarding misconfigured reprotest configurations.

Distribution work In Debian this month, 5 reviews of Debian packages were added, 22 were updated and 8 were removed this month adding to Debian s knowledge about identified issues. A number of issue types were updated as well. [ ][ ][ ][ ] In addition, Roland Clobus posted his 23rd update of the status of reproducible ISO images on our mailing list. In particular, Roland helpfully summarised that all major desktops build reproducibly with bullseye, bookworm, trixie and sid provided they are built for a second time within the same DAK run (i.e. [within] 6 hours) and that there will likely be further work at a MiniDebCamp in Hamburg. Furthermore, Roland also responded in-depth to a query about a previous report
Fedora developer Zbigniew J drzejewski-Szmek announced a work-in-progress script called fedora-repro-build that attempts to reproduce an existing package within a koji build environment. Although the projects README file lists a number of fields will always or almost always vary and there is a non-zero list of other known issues, this is an excellent first step towards full Fedora reproducibility.
Jelle van der Waa introduced a new linter rule for Arch Linux packages in order to detect cache files leftover by the Sphinx documentation generator which are unreproducible by nature and should not be packaged. At the time of writing, 7 packages in the Arch repository are affected by this.
Elsewhere, Bernhard M. Wiedemann posted another monthly update for his work elsewhere in openSUSE.

diffoscope diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues. This month, Chris Lamb made a number of changes such as uploading versions 256, 257 and 258 to Debian and made the following additional changes:

• Use a deterministic name instead of trusting gpg s use-embedded-filenames. Many thanks to Daniel Kahn Gillmor dkg@debian.org for reporting this issue and providing feedback. [ ][ ]
• Don t error-out with a traceback if we encounter struct.unpack-related errors when parsing Python .pyc files. (#1064973). [ ]
• Don t try and compare rdb_expected_diff on non-GNU systems as %p formatting can vary, especially with respect to MacOS. [ ]
• Fix compatibility with pytest 8.0. [ ]
• Temporarily fix support for Python 3.11.8. [ ]
• Use the 7zip package (over p7zip-full) after a Debian package transition. (#1063559). [ ]
• Bump the minimum Black source code reformatter requirement to 24.1.1+. [ ]
• Expand an older changelog entry with a CVE reference. [ ]
• Make test_zip black clean. [ ]

In addition, James Addison contributed a patch to parse the headers from the diff(1) correctly [ ][ ] thanks! And lastly, Vagrant Cascadian pushed updates in GNU Guix for diffoscope to version 255, 256, and 258, and updated trydiffoscope to 67.0.6.

reprotest reprotest is our tool for building the same source code twice in different environments and then checking the binaries produced by each build for any differences. This month, Vagrant Cascadian made a number of changes, including:

• Create a (working) proof of concept for enabling a specific number of CPUs. [ ][ ]
• Consistently use 398 days for time variation rather than choosing randomly and update README.rst to match. [ ][ ]
• Support a new --vary=build_path.path option. [ ][ ][ ][ ]

Website updates There were made a number of improvements to our website this month, including:

• Chris Lamb:
  • Improve the relative sizing of headers. [ ]
  • Re-order and punch up the introduction and documentation on the SOURCE_DATE_EPOCH page. [ ]
  • Update SOURCE_DATE_EPOCH documentation re. datetime.datetime.fromtimestamp. Thanks, James Addison. [ ]
  • Add a post about Reproducible Builds at FOSDEM 2024. [ ]
• Holger Levsen:
  • Update the GNU Guix page to include their reproducibility QA page. [ ]
  • Add Sune Vuorela and Jan-Benedict Glaw to our contributors list. [ ][ ]
• Mattia Rizzolo:
  • Add Sovereign Tech Fund s logo to our sponsors. [ ]
  • Update our sponsors list. [ ]

Reproducibility testing framework The Reproducible Builds project operates a comprehensive testing framework (available at tests.reproducible-builds.org) in order to check packages and other artifacts for reproducibility. In February, a number of changes were made by Holger Levsen:

• Debian-related changes:
  • Temporarily disable upgrading/bootstrapping Debian unstable and experimental as they are currently broken. [ ][ ]
  • Use the 64-bit amd64 kernel on all i386 nodes; no more 686 PAE kernels. [ ]
  • Add an Erlang package set. [ ]
• Other changes:
  • Grant Jan-Benedict Glaw shell access to the Jenkins node. [ ]
  • Enable debugging for NetBSD reproducibility testing. [ ]
  • Use /usr/bin/du --apparent-size in the Jenkins shell monitor. [ ]
  • Revert reproducible nodes: mark osuosl2 as down . [ ]
  • Thanks again to Codethink, for they have doubled the RAM on our arm64 nodes. [ ]
  • Only set /proc/$pid/oom_score_adj to -1000 if it has not already been done. [ ]
  • Add the opemwrt-target-tegra and jtx task to the list of zombie jobs. [ ][ ]

Vagrant Cascadian also made the following changes:

• Overhaul the handling of OpenSSH configuration files after updating from Debian bookworm. [ ][ ][ ]
• Add two new armhf architecture build nodes, virt32z and virt64z, and insert them into the Munin monitoring. [ ][ ] [ ][ ]

In addition, Alexander Couzens updated the OpenWrt configuration in order to replace the tegra target with mpc85xx [ ], Jan-Benedict Glaw updated the NetBSD build script to use a separate $TMPDIR to mitigate out of space issues on a tmpfs-backed /tmp [ ] and Zheng Junjie added a link to the GNU Guix tests [ ]. Lastly, node maintenance was performed by Holger Levsen [ ][ ][ ][ ][ ][ ] and Vagrant Cascadian [ ][ ][ ][ ].

How we executed a critical supply chain attack on PyTorch John Stawinski and Adnan Khan published a lengthy blog post detailing how they executed a supply-chain attack against PyTorch, a popular machine learning platform used by titans like Google, Meta, Boeing, and Lockheed Martin :

Our exploit path resulted in the ability to upload malicious PyTorch releases to GitHub, upload releases to [Amazon Web Services], potentially add code to the main repository branch, backdoor PyTorch dependencies the list goes on. In short, it was bad. Quite bad.

The attack pivoted on PyTorch s use of self-hosted runners as well as submitting a pull request to address a trivial typo in the project s README file to gain access to repository secrets and API keys that could subsequently be used for malicious purposes.

New Arch Linux forensic filesystem tool On our mailing list this month, long-time Reproducible Builds developer kpcyrd announced a new tool designed to forensically analyse Arch Linux filesystem images. Called archlinux-userland-fs-cmp, the tool is supposed to be used from a rescue image (any Linux) with an Arch install mounted to, [for example], /mnt. Crucially, however, at no point is any file from the mounted filesystem eval d or otherwise executed. Parsers are written in a memory safe language. More information about the tool can be found on their announcement message, as well as on the tool s homepage. A GIF of the tool in action is also available.

Issues with our SOURCE_DATE_EPOCH code? Chris Lamb started a thread on our mailing list summarising some potential problems with the source code snippet the Reproducible Builds project has been using to parse the SOURCE_DATE_EPOCH environment variable:

I m not 100% sure who originally wrote this code, but it was probably sometime in the ~2015 era, and it must be in a huge number of codebases by now. Anyway, Alejandro Colomar was working on the shadow security tool and pinged me regarding some potential issues with the code. You can see this conversation here.

Chris ends his message with a request that those with intimate or low-level knowledge of time_t, C types, overflows and the various parsing libraries in the C standard library (etc.) contribute with further info.

Distribution updates In Debian this month, Roland Clobus posted another detailed update of the status of reproducible ISO images on our mailing list. In particular, Roland helpfully summarised that all major desktops build reproducibly with bullseye, bookworm, trixie and sid provided they are built for a second time within the same DAK run (i.e. [within] 6 hours) . Additionally 7 of the 8 bookworm images from the official download link build reproducibly at any later time. In addition to this, three reviews of Debian packages were added, 17 were updated and 15 were removed this month adding to our knowledge about identified issues. Elsewhere, Bernhard posted another monthly update for his work elsewhere in openSUSE.

Community updates There were made a number of improvements to our website, including Bernhard M. Wiedemann fixing a number of typos of the term nondeterministic . [ ] and Jan Zerebecki adding a substantial and highly welcome section to our page about SOURCE_DATE_EPOCH to document its interaction with distribution rebuilds. [ ].
diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues. This month, Chris Lamb made a number of changes such as uploading versions 254 and 255 to Debian but focusing on triaging and/or merging code from other contributors. This included adding support for comparing eXtensible ARchive (.XAR/.PKG) files courtesy of Seth Michael Larson [ ][ ], as well considerable work from Vekhir in order to fix compatibility between various and subtle incompatible versions of the progressbar libraries in Python [ ][ ][ ][ ]. Thanks!

Reproducibility testing framework The Reproducible Builds project operates a comprehensive testing framework (available at tests.reproducible-builds.org) in order to check packages and other artifacts for reproducibility. In January, a number of changes were made by Holger Levsen:

• Debian-related changes:
  • Reduce the number of arm64 architecture workers from 24 to 16. [ ]
  • Use diffoscope from the Debian release being tested again. [ ]
  • Improve the handling when killing unwanted processes [ ][ ][ ] and be more verbose about it, too [ ].
  • Don t mark a job as failed if process marked as to-be-killed is already gone. [ ]
  • Display the architecture of builds that have been running for more than 48 hours. [ ]
  • Reboot arm64 nodes when they hit an OOM (out of memory) state. [ ]
• Package rescheduling changes:
  • Reduce IRC notifications to 1 when rescheduling due to package status changes. [ ]
  • Correctly set SUDO_USER when rescheduling packages. [ ]
  • Automatically reschedule packages regressing to FTBFS (build failure) or FTBR (build success, but unreproducible). [ ]
• OpenWrt-related changes:
  • Install the python3-dev and python3-pyelftools packages as they are now needed for the sunxi target. [ ][ ]
  • Also install the libpam0g-dev which is needed by some OpenWrt hardware targets. [ ]
• Misc:
  • As it s January, set the real_year variable to 2024 [ ] and bump various copyright years as well [ ].
  • Fix a large (!) number of spelling mistakes in various scripts. [ ][ ][ ]
  • Prevent Squid and Systemd processes from being killed by the kernel s OOM killer. [ ]
  • Install the iptables tool everywhere, else our custom rc.local script fails. [ ]
  • Cleanup the /srv/workspace/pbuilder directory on boot. [ ]
  • Automatically restart Squid if it fails. [ ]
  • Limit the execution of chroot-installation jobs to a maximum of 4 concurrent runs. [ ][ ]

Significant amounts of node maintenance was performed by Holger Levsen (eg. [ ][ ][ ][ ][ ][ ][ ] etc.) and Vagrant Cascadian (eg. [ ][ ][ ][ ][ ][ ][ ][ ]). Indeed, Vagrant Cascadian handled an extended power outage for the network running the Debian armhf architecture test infrastructure. This provided the incentive to replace the UPS batteries and consolidate infrastructure to reduce future UPS load. [ ] Elsewhere in our infrastructure, however, Holger Levsen also adjusted the email configuration for @reproducible-builds.org to deal with a new SMTP email attack. [ ]

Upstream patches The Reproducible Builds project tries to detects, dissects and fix as many (currently) unreproducible packages as possible. We endeavour to send all of our patches upstream where appropriate. This month, we wrote a large number of such patches, including:

• Bernhard M. Wiedemann:
  • cython (nondeterminstic path issue)
  • deluge (issue with modification time of .egg file)
  • gap-ferret, gap-semigroups & gap-simpcomp (nondeterministic config.log file)
  • grpc (filesystem ordering issue )
  • hub (random)
  • kubernetes1.22 & kubernetes1.23 (sort-related issue)
  • kubernetes1.24 & kubernetes1.25 (go -trimpath vs random issue)
  • libjcat (drop test files with random bytes)
  • luajit (Use new d option for deterministic bytecode output)
  • meson [ ][ ] (sort the results from Python filesystem call)
  • python-rjsmin (drop GCC instrumentation artifacts)
  • qt6-virtualkeyboard+others (bug parallelism/race)
  • SoapySDR (parallelism-related issue)
  • systemd (sorting problem)
  • warewulf (CPIO modification time issue, etc.)
• Chris Lamb:
  • #1060254 filed against mumble.
• James Addison:
  • guake ( Schroedinger file due to race condition)
  • qhelpgenerator-qt5 (timezone localization; fix also merged upstream for QT6)
  • sphinx (search index doctitle sorting)

Separate to this, Vagrant Cascadian followed up with the relevant maintainers when reproducibility fixes were not included in newly-uploaded versions of the mm-common package in Debian this was quickly fixed, however. [ ]
