Fran ois Marier: Blocking comment spammers on an Ikiwiki blog

Despite comments on my ikiwiki blog being fully moderated, spammers have been increasingly posting link spam comments on my blog. While I used to use the blogspam plugin, the underlying service was likely retired circa 2017 and its public repositories are all archived. It turns out that there is a relatively simple way to drastically reduce the amount of spam submitted to the moderation queue: ban the datacentre IP addresses that spammers are using.

Looking up AS numbers It all starts by looking at the IP address of a submitted comment:

From there, we can look it up using whois:

$ whois -r 2a0b:7140:1:1:5054:ff:fe66:85c5

The important bit here is this line:

origin:         AS207408

which referts to Autonomous System 207408, owned by a hosting company in Germany called Servinga.

Looking up IP blocks Autonomous Systems are essentially organizations to which IPv4 and IPv6 blocks have been allocated. These allocations can be looked up easily on the command line either using a third-party service:

$ curl -sL https://ip.guide/as207408   jq .routes.v4 >> servinga
$ curl -sL https://ip.guide/as207408   jq .routes.v6 >> servinga

or a local database downloaded from IPtoASN. This is what I ended up with in the case of Servinga:

[
  "45.11.183.0/24",
  "80.77.25.0/24",
  "194.76.227.0/24"
]
[
  "2a0b:7140:1::/48"
]

Preventing comment submission While I do want to eliminate this source of spam, I don't want to block these datacentre IP addresses outright since legitimate users could be using these servers as VPN endpoints or crawlers. I therefore added the following to my Apache config to restrict the CGI endpoint (used only for write operations such as commenting):

<Location /blog.cgi>
        Include /etc/apache2/spammers.include
        Options +ExecCGI
        AddHandler cgi-script .cgi
</Location>

and then put the following in /etc/apache2/spammers.include:

<RequireAll>
    Require all granted
    # https://ipinfo.io/AS207408
    Require not ip 46.11.183.0/24
    Require not ip 80.77.25.0/24
    Require not ip 194.76.227.0/24
    Require not ip 2a0b:7140:1::/48
</RequireAll>

Finally, I can restart the website and commit my changes:

$ apache2ctl configtest && systemctl restart apache2.service
$ git commit -a -m "Ban all IP blocks from Servinga"

Future improvements I will likely automate this process in the future, but at the moment my blog can go for a week without a single spam message (down from dozens every day). It's possible that I've already cut off the worst offenders. I have published the list I am currently using.

Petter Reinholdtsen: 121 packages in Debian mapped to hardware for automatic recommendation

For some years now, I have been working on a automatic hardware based package recommendation system for Debian and other Linux distributions. The isenkram system I started on back in 2013 now consist of two subsystems, one locating firmware files using the information provided by apt-file, and one matching hardware to packages using information provided by AppStream. The former is very similar to the mechanism implemented in debian-installer to pick the right firmware packages to install. This post is about the latter system. Thanks to steady progress and good help from both other Debian and upstream developers, I am happy to report that the Isenkram system now are able to recommend 121 packages using information provided via AppStream. The mapping is done using modalias information provided by the kernel, the same information used by udev when creating device files, and the kernel when deciding which kernel modules to load. To get all the modalias identifiers relevant for your machine, you can run the following command on the command line:

find /sys/devices -name modalias -print0   xargs -0 sort -u

The modalias identifiers can look something like this:

acpi:PNP0000
cpu:type:x86,ven0000fam0006mod003F:feature:,0000,0001,0002,0003,0004,0005,0006,0007,0008,0009,000B,000C,000D,000E,000F,0010,0011,0013,0015,0016,0017,0018,0019,001A,001B,001C,001D,001F,002B,0034,003A,003B,003D,0068,006B,006C,006D,006F,0070,0072,0074,0075,0076,0078,0079,007C,0080,0081,0082,0083,0084,0085,0086,0087,0088,0089,008B,008C,008D,008E,008F,0091,0092,0093,0094,0095,0096,0097,0098,0099,009A,009B,009C,009D,009E,00C0,00C5,00E1,00E3,00EB,00ED,00F0,00F1,00F3,00F5,00F6,00F9,00FA,00FB,00FD,00FF,0100,0101,0102,0103,0111,0120,0121,0123,0125,0127,0128,0129,012A,012C,012D,0140,0160,0161,0165,016C,017B,01C0,01C1,01C2,01C4,01C5,01C6,01F9,024A,025A,025B,025C,025F,0282

The entries above are a selection of the complete set available on a Dell PowerEdge R730 machine I have access to, to give an idea about the various styles of hardware identifiers presented in the modalias format. When looking up relevant packages in a Debian Testing installation on the same R730, I get this list of packages proposed:

% sudo isenkram-lookup
firmware-bnx2x
firmware-nvidia-graphics
firmware-qlogic
megactl
wsl
%

The list consist of firmware packages requested by kernel modules, as well packages with program to get the status from the RAID controller and to maintain the LAN console. When the edac-utils package providing tools to check the ECC RAM status will enter testing in a few days, it will also show up as a proposal from isenkram. In addition, once the mfiutil package we uploaded in October get past the NEW processing, it will also propose a tool to configure the RAID controller. Another example is the trusty old Lenovo Thinkpad X230, which have hardware handled by several packages in the archive. This is running on Debian Stable:

% isenkram-lookup 
beignet-opencl-icd
bluez
cheese
ethtool
firmware-iwlwifi
firmware-misc-nonfree
fprintd
fprintd-demo
gkrellm-thinkbat
hdapsd
libpam-fprintd
pidgin-blinklight
thinkfan
tlp
tp-smapi-dkms
tpb
%

Here there proposal consist of software to handle the camera, bluetooth, network card, wifi card, GPU, fan, fingerprint reader and acceleration sensor on the machine. Here is the complete set of packages currently providing hardware mapping via AppStream in Debian Unstable: air-quality-sensor, alsa-firmware-loaders, antpm, array-info, avarice, avrdude, bmusb-v4l2proxy, brltty, calibre, colorhug-client, concordance-common, consolekit, dahdi-firmware-nonfree, dahdi-linux, edac-utils, eegdev-plugins-free, ekeyd, elogind, firmware-amd-graphics, firmware-ath9k-htc, firmware-atheros, firmware-b43-installer, firmware-b43legacy-installer, firmware-bnx2, firmware-bnx2x, firmware-brcm80211, firmware-carl9170, firmware-cavium, firmware-intel-graphics, firmware-intel-misc, firmware-ipw2x00, firmware-ivtv, firmware-iwlwifi, firmware-libertas, firmware-linux-free, firmware-mediatek, firmware-misc-nonfree, firmware-myricom, firmware-netronome, firmware-netxen, firmware-nvidia-graphics, firmware-qcom-soc, firmware-qlogic, firmware-realtek, firmware-ti-connectivity, fpga-icestorm, g810-led, galileo, garmin-forerunner-tools, gkrellm-thinkbat, goldencheetah, gpsman, gpstrans, gqrx-sdr, i8kutils, imsprog, ledger-wallets-udev, libairspy0, libam7xxx0.1, libbladerf2, libgphoto2-6t64, libhamlib-utils, libm2k0.9.0, libmirisdr4, libnxt, libopenxr1-monado, libosmosdr0, librem5-flash-image, librtlsdr0, libticables2-8, libx52pro0, libykpers-1-1, libyubikey-udev, limesuite, linuxcnc-uspace, lomoco, madwimax, media-player-info, megactl, mixxx, mkgmap, msi-keyboard, mu-editor, mustang-plug, nbc, nitrokey-app, nqc, ola, openfpgaloader, openocd, openrazer-driver-dkms, pcmciautils, pcscd, pidgin-blinklight, ponyprog, printer-driver-splix, python-yubico-tools, python3-btchip, qlcplus, rosegarden, scdaemon, sispmctl, solaar, spectools, sunxi-tools, t2n, thinkfan, tlp, tp-smapi-dkms, trezor, tucnak, ubertooth, usbrelay, uuu, viking, w1retap, wsl, xawtv, xinput-calibrator, xserver-xorg-input-wacom and xtrx-dkms. In addition to these, there are several with patches pending in the Debian bug tracking system, and even more where no-one wrote patches yet. Good candiates for the latter are packages with udev rules but no AppStream hardware information. The isenkram system consist of two packages, isenkram-cli with the command line tools, and isenkram with a GUI background process. The latter will listen for dbus events from udev emitted when new hardware become available (like when inserting a USB dongle or discovering a new bluetooth device), look up the modalias entry for this piece of hardware in AppStream (and a hard coded list of mappings from isenkram - currently working hard to move this list to AppStream), and pop up a dialog proposing to install any not already installed packages supporting this hardware. It work very well today when inserting the LEGO Mindstorms RCX, NXT and EV3 controllers. :) If you want to make sure more hardware related packages get recommended, please help out fixing the remaining packages in Debian to provide AppStream metadata with hardware mappings.

Petter Reinholdtsen: What is the most supported MIME type in Debian in 2025?

Seven and twelve years ago, I measured what the most supported MIME type in Debian was, first by analysing the desktop files in all packages in the archive, then by analysing the DEP-11 AppStream data set. I guess it is time to repeat the measurement, only for unstable as last time: Debian Unstable:

  count MIME type
  ----- -----------------------
     63 image/png
     63 image/jpeg
     57 image/tiff
     54 image/gif
     51 image/bmp
     50 audio/mpeg
     48 text/plain
     42 audio/x-mp3
     40 application/ogg
     39 audio/x-wav
     39 audio/x-flac
     36 audio/x-vorbis+ogg
     35 audio/x-mpeg
     34 audio/x-mpegurl
     34 audio/ogg
     33 application/x-ogg
     32 audio/mp4
     31 audio/x-scpls
     31 application/pdf
     29 audio/x-ms-wma

The list was created like this using a sid chroot:

cat /var/lib/apt/lists/*sid*_dep11_Components-amd64.yml.gz   \
  zcat   awk '/^  - \S+\/\S+$/  print $2  '   sort   \
  uniq -c   sort -nr   head -20

It is nice to see that the same number of packages now support PNG and JPEG. Last time JPEG had more support than PNG. Most of the MIME types are known to me, but the 'audio/x-scpls' one I have no idea what represent, except it being an audio format. To find the packages claiming support for this format, the appstreamcli command from the appstream package can be used:

% appstreamcli what-provides mediatype audio/x-scpls   grep Package:   sort -u
Package: alsaplayer-common
Package: amarok
Package: audacious
Package: brasero
Package: celluloid
Package: clapper
Package: clementine
Package: cynthiune.app
Package: elisa
Package: gtranscribe
Package: kaffeine
Package: kmplayer
Package: kylin-burner
Package: lollypop
Package: mediaconch-gui
Package: mediainfo-gui
Package: mplayer-gui
Package: mpv
Package: mystiq
Package: parlatype
Package: parole
Package: pragha
Package: qmmp
Package: rhythmbox
Package: sayonara
Package: shotcut
Package: smplayer
Package: soundconverter
Package: strawberry
Package: syncplay
Package: vlc
%

Look like several video and auto tools understand the format. Similarly one can check out the number of packages supporting the STL format commonly used for 3D printing:

% appstreamcli what-provides mediatype model/stl   grep Package:   sort -u
Package: cura
Package: freecad
Package: open3d-viewer
%

How strange the slic3r and prusa-slicer packages do not support STL. Perhaps just missing package metadata? Luckily the amount of package metadata in Debian is getting better, and hopefully this way of locating relevant packages for any file format will be the preferred one soon. As usual, if you use Bitcoin and want to show your support of my activities, please send Bitcoin donations to my address 15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.

Dominique Dumont: How we solved storage API throttling on our Azure Kubernetes clusters

Hi This issue was quite puzzling, so I m sharing how we investigated this issue. I hope it can be useful for you. My client informed me that he was no longer able to install new instances of his application. k9s showed that only some pods could not be created, only the ones that created physical volume (PV). The description of these pods showed a HTTP error 429 when creating pods: New PVC could not be created because we were throttled by Azure storage API. This issue was confirmed by Azure diagnostic console on Kubernetes ( menu Diagnose and solve problems Cluster and Control Plane Availability and Performance Azure Resource Request Throttling ). We had a lot of throttling:

Which were explained by the high call rate:

The first clue was found at the bottom of Azure diagnostic page:

According, to this page, throttling is done by services whose user agent is:

Go/go1.23.1 (amd64-linux) go-autorest/v14.2.1 Azure-SDK-For-Go/v68.0.0
storage/2021-09-01microsoft.com/aks-operat azsdk-go-armcompute/v1.0.0 (go1.22.3; linux)

The main information is Azure-SDK-For-Go, which means the program making all these calls to storage API is written in Go. All our services are written in Typescript or Rust, so they are not suspect. That leaves controllers running in kube-systems namespace. I could not find anything suspects in the logs of these services. At that point I was convinced that a component in Kubernetes control plane was making all those calls. Unfortunately, AKS is managed by Microsoft and I don t have access to the control plane logs. However, we re realized that we had quite a lot of volumesnapshots that are created in our clusters using k8s-scheduled-volume-snapshotter:

about 1800 on dev instead of 240
1070 on preprod instead of 180
6800 on prod instead of 2400

We suspected that kubernetes reconciliation loop is throttled when checking the status of all these snapshots. May be so, but we also had the same issues and throttle rates on preprod and prod were the number of snapshots were quite different. We tried to get more information using Azure console on our snapshot account, but it was also broken by the throttling issue. We were so puzzled that we decided to try L odagan s advice (tout cr mer pour repartir sur des bases saines, loosely translated as burn everything down to start from scratch ) and we destroyed piece by piece our dev cluster while checking if the throttling stopped. First, we removed all our applications, no change. Then, all ancillary components like rabbitmq, cert-manager were removed, no change. Then, we tried remove the namespace containing our applications. But, we faced another issue: Kubernetes was unable to remove the namespace because it could not destroy some PVC and volumesnapshots. That was actually good news, because it meant that we were close to the actual issue. We managed to destroy the PVC and volumesnapshots by removing their finalizers. Finalizers are some kind of markers that tell kubernetes that something needs to be done before actually deleting a resource. The finalizers were removed with a command like:

kubectl patch volumesnapshots $ volumesnapshot  \
  -p ' \"metadata\": \"finalizers\":null '  --type merge

Then, we got the first progress : the throttling and high call rate stopped on our dev cluster. To make sure that the snapshots were the issue, we re-installed the ancillary components and our applications. Everything was copacetic. So, the problem was indeed with PVC and snapshots. Even though we have backups outside of Azure, we weren t really thrilled at trying L odagan s method on our prod cluster So we looked for a better fix to try on our preprod cluster. Poking around in PVC and volumesnapshots, I finally found this error message in the description on a volumesnapshotcontents:

Code="ShareSnapshotCountExceeded" Message="The total number of snapshots
for the share is over the limit."

The number of snapshots found in our cluster was not that high. So I wanted to check the snapshots present in our storage account using Azure console, which was still broken. Fortunately, Azure CLI is able to retry HTTP calls when getting 429 errors. I managed to get a list of snapshots with

az storage share list --account-name [redacted] --include-snapshots \
      tee preprod-list.json

There, I found a lot of snapshots dating back from 2024. These were no longer managed by Kubernetes and should have been cleaned up. That was our smoking gun. I guess that we had a chain of events like:

too many snapshots in some volumes
Kubernetes control plane tries to reconcile its internal status with Azure resources and frequently retries snapshot creation
API throttling kicks in
client not happy

To make things worse, k8s-scheduled-volume-snapshotter creates new snapshots when it cannot list the old ones. So we had 4 new snapshots per day instead of one. Since we had the chain of events, fixing the issue was not too difficult (but quite long ):

stop k8s-scheduled-volume-snapshotter by disabling its cron job
delete all volumesnapshots and volume snapshots contents from k8s.
since Azure API was throttled, we also had to remove their finalizers
delete all snapshots from azure using az command and a Perl script (this step took several hours)
re-enable k8s-scheduled-volume-snapshotter

After these steps, preprod was back to normal. I m now applying the same recipe on prod. We still don t know why we had all these stale snapshots. It may have been a human error or a bug in k8s-scheduled-volume-snapshotter. Anyway, to avoid this problem is the future, we will:

setup an alert on the number of snapshots per volume
check with k8s-scheduled-volume-snapshotter author to better cope with throttling

Russell Coker: Systemd Hardening and Sending Mail

A feature of systemd is the ability to reduce the access that daemons have to the system. The restrictions include access to certain directories, system calls, capabilities, and more. The systemd.exec(5) man page describes them all [1]. To see an overview of the security of daemons run systemd-analyze security and to get details of one particular daemon run a command like systemd-analyze security mon.service . I created a Debian wiki page for a systemd-analyze security goal [2]. At this time release goals aren t a serious thing for Debian so this won t result in release critical bug reports, but it is still something we can aim for. For a simple daemon (EG BIND, dhcpd, and syslogd) this isn t difficult to do. It might be difficult to understand the implications of some changes (especially when restricting system calls) but you can do some quick tests. The functionality of such programs has a limited scope and once you get it basically working it s done. For some daemons it s harder. Network-Manager is one of the well known slightly more difficult cases as it could do things like starting a VPN connection. The larger scope and the use of plugins makes it difficult to test the combinations. The systemd restrictions apply to child processes too unlike restrictions by SE Linux and AppArmor which permit a child process to run in a different security context. The messages when a daemon fails due to systemd restrictions are usually unclear which makes things harder to setup and makes it more important to get it right. My mon package (which I forked upstream as etbe-mon [3] is one of the difficult daemons as local test can involve probing large parts of the system. But I have got that working reasonably well for most cases. I have a bug report about running mon with Exim [4]. The problem with this is that Exim has a single process model which means that the process doing local delivery can be a child of the process that initially received the message. So the main mon process needs all the access for delivering mail (writing to /home etc). This also means that every other child of mon will get such access including programs that receive untrusted data from the Internet. Most of the extra access needed by Exim is not a problem, but /home access is a potential risk. It also means that more effort is needed when reviewing the access control. The problem with this Exim design is that it applies to many daemons. Every daemon that sends email or that potentially could send email in some configuration needs extra access to be granted. Can Exim be configured to have it s sendmail -T type operation just write a file in a spool directory for another program to process? Do we need to grant permissions to most of the system just for Exim?

Thomas Lange: FAI 6.2.5 and new ISO available

The new years starts with a FAI release. FAI 6.2.5 is available and contains many small improvements. A new feature is that the command fai-cd can now create ISOs for the ARM64 architecture. The FAIme service uses the newest FAI version and the Debian most recent point release 12.9. The FAI CD images were also updated. The Debian packages of FAI 6.2.5 are available for Debian stable (aka bookworm) via the FAI repository adding this line to sources.list:

deb https://fai-project.org/download bookworm koeln

Using the tool extrepo, you can also add the FAI repository to your host

# extrepo enable fai

FAI 6.2.5 will soon be available in Debian testing via the official Debian mirrors.

Kentaro Hayashi: Stick to boot from 6.11 linux-image

Since Dec 2024, there is a compatibility issue with linux-image 6.12 and nvidia-driver 535.216.03. #1089513 - nvidia-driver: crash in drm_open_helper on Linux 6.12.3 - Debian Bug report logs It seems that the upstream was already fixed this issue in newer release, but not available yet on Debian sid. If you keep installed linux-image-amd64 or linux-headers-amd64, it will be booted from 6.12 by default. Surely it will boot, but it still has the resolution issue. It can't be your daily driver. Thus workaround is sticking to boot from 6.11 linux-image. As usually older image was listed in "Advanced options for ..." submenu, you need to explicitly choose 6.11 image during booting. In such a case, the changing default boot image is useful. (another option is just purge all 6.12 linux-image, linux-image-amd64 and linux-headers-amd64, but it's out of scope in this article) See /boot/grub/grub.cfg and collect each menuentry_id_option. You need to collect the following menuentry id.

submenu menuentry's id (It might be 'gnulinux-advanced-.....') [1]
6.11 kernel's menuentry id which you want to boot by default. (It might be 'gnulinux-6.11.10-amd64-advanced-...') [2]

Then, edit GRUB_DEFAULT entry in /etc/default/grub. GRUB_DEFAULT should be combination with [1] and [2] which is concatenated with ">" e.g. NOTE: the actual value might vary on your environment

GRUB_DEFAULT="gnulinux-advanced-2e0e7dd0-7e10-4b58-92f7-518dabb5b547>gnulinux-6.11.10-amd64-advanced-2e0e7dd0-7e10-4b58-92f7-518dabb5b547"

After that, update grub entry with sudo update-grub. /boot/grub/grub.cfg will be updated correctly.

Thorsten Alteholz did 11.0h (out of 11.0h assigned).

Tobias Frost did 12.0h (out of 12.0h assigned).

Evolution of the situation In December, we have released 29 DLAs. The LTS Team has published updates to several notable packages. Contributor Guilhem Moulin published an update of php7.4, a widely-used open source general purpose scripting language, which addressed denial of service, authorization bypass, and information disclosure vulnerabilities. Contributor Lucas Kanashiro published an update of clamav, an antivirus toolkit for Unix and Linux, which addressed denial of service and authorization bypass vulnerabilities. Finally, contributor Tobias Frost published an update of intel-microcode, the microcode for Intel microprocessors, which well help to ensure that processor hardware is protected against several local privilege escalation and local denial of service vulnerabilities. Beyond our customary LTS package updates, the LTS Team has made contributions to Debian s stable bookworm release and its experimental section. Notably, contributor Lee Garrett published a stable update of dnsmasq. The LTS update was previously published in November and in December Lee continued working to bring the same fixes (addressing the high profile KeyTrap and NSEC3 vulnerabilities) to the dnsmasq package in Debian bookworm. This package was accepted for inclusion in the Debian 12.9 point release scheduled for January 2025. Addititionally, contributor Sean Whitton provided assistance, via upload sponsorships, to the Debian maintainers of xen. This assistance resulted in two uploads of xen into Debian s experimental section, which will contribute to the next Debian stable release having a version of xen with better longterm support from the upstream development team.

Divine Attah-Ohiemi: My 30-Day Outreachy Experience with the Debian Community

Hey everyone! It s Divine Attah-Ohiemi here, and I m excited to share what I ve been up to in my internship with the Debian community. It s been a month since I began this journey, and if you re thinking about applying for Outreachy, let me give you a glimpse into my project and the amazing people I get to work with. So, what s it like in the Debian community? It s a fantastic mix of folks from all walks of life seasoned developers, curious newbies, and everyone in between. What really stands out is how welcoming everyone is. I m especially thankful to my mentors, Thomas Lange, Carsten Schoenert, and Subin Siby, for their guidance and for always clocking in whenever I have questions. It feels like a big family where you can share your ideas and learn from each other. The commitment to diversity and merit is palpable, making it a great place for anyone eager to jump in and contribute. Now, onto the project! We re working on improving the Debian website by switching from WML (Web Meta Language) to Hugo, a modern static site generator. This change doesn t just make the site faster; it significantly reduces the time it takes to build compared to WML. Plus, it makes it way easier for non-developers to contribute and add pages since the content is built from Markdown files. It s all about enhancing the experience for both new and existing users. My role involves developing a proof of concept for this transition. I m migrating existing pages while ensuring that old links still work, so users won t run into dead ends. It s a bit of a juggling act, but knowing that my work is helping to make Debian more accessible is incredibly rewarding. What gets me most excited is the chance to contribute to a project that s been around for over 20 years! It s an honor to be part of something so significant and to help shape its future. How cool is it to know that what I m doing will impact users around the globe? In the past month, I ve learned a bunch of new things. For instance, I ve been diving into Apache's mod_rewrite to automatically map old multilingual URLs to new ones. This is important since Hugo handles localization differently than WML. I ve also been figuring out how to set up 301 redirects to prevent dead links, which is crucial for a smooth user experience. One of the more confusing parts has been using GNU Make to manage Perl scripts for dynamic pages. It s a bit of a learning curve, but I m tackling it head-on. Each challenge is a chance to grow, and I m here for it! If you re considering applying to the Debian community through Outreachy, I say go for it! There s so much to learn and experience, and you ll be welcomed with open arms. Happy coding, everyone!

Dirk Eddelbuettel: Rcpp 1.0.14 on CRAN: Regular Semi-Annual Update

The Rcpp Core Team is once again thrilled, pleased, and chuffed (am I doing this right for LinkedIn?) to announce a new release (now at 1.0.14) of the Rcpp package. It arrived on CRAN earlier today, and has since been uploaded to Debian. Windows and macOS builds should appear at CRAN in the next few days, as will builds in different Linux distribution and of course r2u should catch up tomorrow too. The release was only uploaded yesterday, and as always get flagged because of the grandfathered .Call(symbol) as well as for the url to the Rcpp book (which has remained unchanged for years) failing . My email reply was promptly dealt with under European morning hours and by the time I got up the submission was in state waiting over a single reverse-dependency failure which is also spurious, appears on some systems and not others, and also not new. Imagine that: nearly 3000 reverse dependencies and only one (spurious) change to worse. Solid testing seems to help. My thanks as always to the CRAN for responding promptly. This release continues with the six-months January-July cycle started with release 1.0.5 in July 2020. This time we also need a one-off hotfix release 1.0.13-1: we had (accidentally) conditioned an upcoming R change on 4.5.0, but it already came with 4.4.2 so we needed to adjust our code. As a reminder, we do of course make interim snapshot dev or rc releases available via the Rcpp drat repo as well as the r-universe page and repo and strongly encourage their use and testing I run my systems with these versions which tend to work just as well, and are also fully tested against all reverse-dependencies. Rcpp has long established itself as the most popular way of enhancing R with C or C++ code. Right now, 2977 packages on CRAN depend on Rcpp for making analytical code go faster and further. On CRAN, 13.6% of all packages depend (directly) on Rcpp, and 60.8% of all compiled packages do. From the cloud mirror of CRAN (which is but a subset of all CRAN downloads), Rcpp has been downloaded 93.7 million times. The two published papers (also included in the package as preprint vignettes) have, respectively, 1947 (JSS, 2011) and 354 (TAS, 2018) citations, while the the book (Springer useR!, 2013) has another 676. This release is primarily incremental as usual, generally preserving existing capabilities faithfully while smoothing our corners and / or extending slightly, sometimes in response to changing and tightened demands from CRAN or R standards. The move towards a more standardized approach for the C API of R once again to a few changes; Kevin did once again did most of these PRs. Other contributed PRs include G bor permitting builds on yet another BSD variant, Simon Guest correcting sourceCpp() to work on read-only files, Marco Colombo correcting a (surprisingly large) number of vignette typos, I aki rebuilding some documentation files that tickled (false) alerts, and I took care of a number of other maintenance items along the way. The full list below details all changes, their respective PRs and, if applicable, issue tickets. Big thanks from all of us to all contributors!

Changes in Rcpp release version 1.0.14 (2025-01-11)

Changes in Rcpp API:

Support for user-defined databases has been removed (Kevin in #1314 fixing #1313)

The SET_TYPEOF function and macro is no longer used (Kevin in #1315 fixing #1312)

An errorneous cast to int affecting large return object has been removed (Dirk in #1335 fixing #1334)

Compilation on DragonFlyBSD is now supported (G bor Cs rdi in #1338)

Use read-only VECTOR_PTR and STRING_PTR only with with R 4.5.0 or later (Kevin in #1342 fixing #1341)

Changes in Rcpp Attributes:

The sourceCpp() function can now handle input files with read-only modes (Simon Guest in #1346 fixing #1345)

Changes in Rcpp Deployment:

One unit tests for arm64 macOS has been adjusted; a macOS continuous integration runner was added (Dirk in #1324)

Authors@R is now used in DESCRIPTION as mandated by CRAN, the Rcpp.package.skeleton() function also creates it (Dirk in #1325 and #1327)

A single datetime format test has been adjusted to match a change in R-devel (Dirk in #1348 fixing #1347)

Changes in Rcpp Documentation:

The Rcpp Modules vignette was extended slightly following #1322 (Dirk)

Pdf vignettes have been regenerated under Ghostscript 10.03.1 to avoid a false positive by a Windows virus scanner (I aki in #1331)

A (large) number of (old) typos have been corrected in the vignettes (Marco Colombo in #1344)

Thanks to my CRANberries, you can also look at a diff to the previous release Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page. Bugs reports are welcome at the GitHub issue tracker as well (where one can also search among open or closed issues).

This post by Dirk Eddelbuettel originated on his Thinking inside the box blog. If you like this or other open-source work I do, you can sponsor me at GitHub.

Bastian Venthur: Investigating the popularity of Python build backends over time (II)

Last year, I analyzed the popularity of build backends used in pyproject.toml files over time. This post is the update for 2024. Analysis Like last year, I m using Tom Forbes fantastic dataset containing information about every file within every release uploaded to PyPI. To get the current dataset, I followed the same process as in last year s analysis, so I won t repeat all the details here. Instead, I ll highlight the main steps:

Download the parquet files from the dataset
Use DuckDB to query the parquet files, extracting the project name, upload date, the pyproject.toml file, and its hash for each upload
Download each pyproject.toml file and extract the build backend. To avoid redundant downloads, I stored a mapping of the file hash and their respective build backend

Downloading all the parquet files took roughly a week due to GitHub s rate limiting. Tom suggested leveraging the Git v2 protocol to fetch the data directly. This approach could bypass rate limiting and complete the download of all pyproject.toml files in just 20 minutes(!). However, I couldn t find sufficient documentation that would help me to implement this method, so this will have to wait until next year s analysis. Once all the data is downloaded, I perform some preprocessing:

Grouped the top 4 build backends by their absolute number of uploads and categorized the remaining ones as other
Binned upload dates into quarters to reduce clutter in the resulting graphs

Results I modified the plots a bit from last year to make them easier to read. Most notably, I binned the data into quarters to make the plots less noisy, and secondly, I stopped stacking the relative distribution plots to make the percentages directly readable. The first plot shows the absolute number of uploads (in thousands) by quarter and build backend.

Absolute distribution of build backends by quarter

The second plot shows the relative distribution of build backends by quarter.

In 2024, we observe that:

Setuptools continues to grow in absolute numbers and remains around the 50% mark in relative distribution
Poetry maintains a 30% relative distribution, but the trend has been declining since 2024-Q3. Preliminary data for 2025-Q1 (not shown here) supports this, suggesting that Poetry might be surpassed by Hatch in 2025, which showed a remarkable growth last year.
Flit is the only build backend in this analysis whose absolute and relative numbers decreased in 2024. With a 5% relative distribution, it underlines the dominance of Setuptools, Poetry, and Hatch over the remaining build backends.

The script for downloading and analyzing the data is available in my GitHub repository. If someone has insights or examples on implementing the Git v2 protocol to download the pyproject.toml file given the repository URL and its hash, I d love to hear from you!

Valhalla's Things: Winter

An acrylic painting in blue and greenish grey vaguely resembling rocky slopes at the bottom right and a cloudy sky at the top left.

A few days ago¹ I wanted to paint, but I didn t know what to paint, so I did a few more colour tests to find out which green combinations I can get out of the available yellows and blues (and greens) acrylic I have (from a cheap student grade line). A sheet of colour tests with mixes of various yellows and blues.

A sheet of colour tests with mixes of various yellows and blues.

I liked the cool grey tones in the second to last line, from 200 Naples yellow (PY3 PY83 PW6) and 410 Ultramarine blue (PB29), so I went up a step on the scale of things to do when having a desire to paint, but the utter inability to actually paint something and did a bit of a study with those two colours plus titanium white. The study above over a sheet of scrap paper: at one of the edge the excess paint has connected the two together.

The study above over a sheet of scrap paper: at one of the edge the excess paint has connected the two together.

And btw, painting with acrylics on watercolour paper taped to a sheet of scrap paper works just fine for stuff like this that is not supposed to last, but the work will get glued to the paper below when (not if) the paint overflows :D

i.e. almost three months, and then I wrote 95% of this post and forgot to finish and publish it.

Reproducible Builds: Reproducible Builds in December 2024

Welcome to the December 2024 report from the Reproducible Builds project! Our monthly reports outline what we ve been up to over the past month and highlight items of news from elsewhere in the world of software supply-chain security when relevant. As ever, however, if you are interested in contributing to the Reproducible Builds project, please visit our Contribute page on our website. Table of contents:

reproduce.debian.net Last month saw the introduction of reproduce.debian.net. Announced at the recent Debian MiniDebConf in Toulouse, reproduce.debian.net is an instance of rebuilderd operated by the Reproducible Builds project. rebuilderd is our server designed monitor the official package repositories of Linux distributions and attempts to reproduce the observed results there. This month, however, we are pleased to announce that not only does the service now produce graphs, the reproduce.debian.net homepage itself has become a start page of sorts, and the amd64.reproduce.debian.net and i386.reproduce.debian.net pages have emerged. The first of these rebuilds the `amd64` architecture, naturally, but it also is building Debian packages that are marked with the no architecture label, `all`. The second builder is, however, only rebuilding the `i386` architecture. Both of these services were also switched to reproduce the Debian trixie distribution instead of unstable, which started with 43% of the archive rebuild with 79.3% reproduced successfully. This is very much a work in progress, and we ll start reproducing Debian unstable soon. Our `i386` hosts are very kindly sponsored by Infomaniak whilst the `amd64` node is sponsored by OSUOSL thank you! Indeed, we are looking for more workers for more Debian architectures; please contact us if you are able to help.

debian-repro-status Reproducible builds developer kpcyrd has published a client program for reproduce.debian.net (see above) that queries the status of the locally installed packages and rates the system with a percentage score. This tool works analogously to arch-repro-status for the Arch Linux Reproducible Builds setup. The tool was packaged for Debian and is currently available in Debian trixie: it can be installed with `apt install debian-repro-status`.

On our mailing list On our mailing list this month:

Bernhard M. Wiedemann wrote a detailed post on his long journey towards a bit-reproducible Emacs package. In his interesting message, Bernhard goes into depth about the tools that they used and the lower-level technical details of, for instance, compatibility with the version for `glibc` within openSUSE.

Shivanand Kunijadar posed a question pertaining to the reproducibility issues with encrypted images. Shivanand explains that they must use a random IV for encryption with AES CBC. The resulting artifact is not reproducible due to the random IV used. The message resulted in a handful of replies, hopefully helpful!

User Danilo posted an in interesting question related to their attempts in trying to achieve reproducible builds for Threema Desktop 2.0. The question resulted in a number of replies attempting to find the right combination of compiler and linker flags (for example).

Longstanding contributor David A. Wheeler wrote to our list announcing the release of the Census III of Free and Open Source Software: Application Libraries report written by Frank Nagle, Kate Powell, Richie Zitomer and David himself. As David writes in his message, the report attempts to answer the question what is the most popular Free and Open Source Software (FOSS)? .

Lastly, `kpcyrd` followed-up to a post from September 2024 which mentioned their desire for someone to implement a hashset of allowed module hashes that is generated during the kernel build and then embedded in the kernel image , thus enabling a deterministic and reproducible build. However, they are now reporting that somebody implemented the hash-based allow list feature and submitted it to the Linux kernel mailing list . Like `kpcyrd`, we hope it gets merged.

Enhancing the Security of Software Supply Chains: Methods and Practices Mehdi Keshani of the Delft University of Technology in the Netherlands has published their thesis on Enhancing the Security of Software Supply Chains: Methods and Practices . Their introductory summary first begins with an outline of software supply chains and the importance of the Maven ecosystem before outlining the issues that it faces that threaten its security and effectiveness . To address these:
First, we propose an automated approach for library reproducibility to enhance library security during the deployment phase. We then develop a scalable call graph generation technique to support various use cases, such as method-level vulnerability analysis and change impact analysis, which help mitigate security challenges within the ecosystem. Utilizing the generated call graphs, we explore the impact of libraries on their users. Finally, through empirical research and mining techniques, we investigate the current state of the Maven ecosystem, identify harmful practices, and propose recommendations to address them.
A PDF of Mehdi s entire thesis is available to download.

diffoscope diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues. This month, Chris Lamb made the following changes, including preparing and uploading versions `283` and `284` to Debian:

Update copyright years. [ ]

Update tests to support file 5.46. [ ][ ]

Simplify `tests_quines.py::test_ differences,differences_deb` to simply use assert_diff and not mangle the test fixture. [ ]

Supply-chain attack in the Solana ecosystem A significant supply-chain attack impacted Solana, an ecosystem for decentralised applications running on a blockchain. Hackers targeted the @solana/web3.js JavaScript library and embedded malicious code that extracted private keys and drained funds from cryptocurrency wallets. According to some reports, about $160,000 worth of assets were stolen, not including SOL tokens and other crypto assets.

Website updates Similar to last month, there was a large number of changes made to our website this month, including:

Chris Lamb:

Make the landing page hero look nicer when the vertical height component of the viewport is restricted, not just the horizontal width.

Rename the Buy-in page to Why Reproducible Builds? [ ]

Removing the top black border. [ ][ ]

Holger Levsen:

Fixed a number of issues on the 2024 Summit page, including fixing the path to a sponsor logo [ ] but also added the event documentation from Aspiration [ ].

Check and cleanup a presentation formerly linked from the About page on the Debian wiki. [ ]

Link to reproduce.debian.net on the Involved Projects page. [ ]

Fix a number of links on the Talks & Resources page. [ ][ ][ ][ ]

hulkoba:

Remove the sidebar-type layout and move to a static navigation element. [ ][ ][ ][ ]

Create and merge a new Success stories page, which highlights the success stories of Reproducible Builds, showcasing real-world examples of projects shipping with verifiable, reproducible builds. These stories aim to enhance the technical resilience of the initiative by encouraging community involvement and inspiring new contributions. . [ ]

Further changes to the homepage. [ ]

Remove the translation icon from the navigation bar. [ ]

Remove unused CSS styles pertaining to the sidebar. [ ]

Add sponsors to the global footer. [ ]

Add extra space on large screens on the Who page. [ ]

Hide the side navigation on small screens on the Documentation pages. [ ]

Debian changes There were a significant number of reproducibility-related changes within Debian this month, including:

Santiago Vila uploaded version `0.11+nmu4` of the `dh-buildinfo` package. In this release, the `dh_buildinfo` becomes a no-op ie. it no longer does anything beyond warning the developer that the `dh-buildinfo` package is now obsolete. In his upload, Santiago wrote that We still want packages to drop their [dependency] on `dh-buildinfo`, but now they will immediately benefit from this change after a simple rebuild.

Holger Levsen filed Debian bug #1091550 requesting a rebuild of a number of packages that were built with a very old version of `dpkg`.

Fay Stegerman contributed to an extensive thread on the `debian-devel` development mailing list on the topic of Supporting alternative zlib implementations . In particular, Fay wrote about her results experimenting whether `zlib-ng` produces identical results or not.

kpcyrd uploaded a new `rust-rebuilderd-worker`, `rust-derp`, `rust-in-toto` and `debian-repro-status` to Debian, which passed successfully through the so-called NEW queue.

Gioele Barabucci filed a number of bugs against the `debrebuild` component/script of the `devscripts` package, including:

#1089087: Address a spurious extra subdirectory in the build path.

#1089201: Extra zero bytes added to `.dynstr` when rebuilding CMake projects.

#1089088: Some binNMUs have a 1-second offset in some timestamps.

Gioele Barabucci also filed a bug against the `dh-r` package to report that the `Recommends` and `Suggests` fields are missing from rebuilt R packages. At the time of writing, this bug has no patch and needs some help to make over 350 binary packages reproducible.

Lastly, 8 reviews of Debian packages were added, 11 were updated and 11 were removed this month adding to our knowledge about identified issues.

Other development news In other ecosystem and distribution news:

Jan-Benedict Glaw published the 6th NetBSD Reproducibility Report and reported on our mailing list as well.

Developer unmush wrote a long post on the GNU Guix blog on the topic of Adding a fully-bootstrapped Mono to the distribution.

The Glasgow Haskell Compiler (GHC) has released a new version of their compiler. This release introduces a new experimental flag, `-fobject-determinism`, which enables deterministic object code generation .

The IzzyOnDroid Android APK repository published an extensive Review of 2024 and Outlook for 2025 which includes statistics and future plans related to reproducible builds (including having passed the 30% mark this month).

The historic Arch Linux reproducibility tests that were hosted at `tests.reproducible-builds.org/archlinux` now redirect to reproducible.archlinux.org instead. In fact, everything Arch-related has now been removed from the `jenkins.debian.net.git` repository, as those continuous integration tests have been disabled for some time.

reprotest version `0.7.29` was uploaded to Debian unstable by Vagrant Cascadian. It included contributions already covered in previous months as well as new ones from Rebecca N. Palmer, such as:

Stop using `pkg_resources`. [ ][ ]

The `as_file` attribute is not a method. [ ]

Use a non-constant object to test memory address capture. [ ]

rebuilderd was updated as follows by kpcyrd:

Migrate `diesel` dependency from 1.x to 2.x. [ ]

Migrate `clap` dependency from 2 to 4. [ ]

Refactor `reqwest` code, and the replace openssl dependency with the memory-safe rustls. [ ][ ]

Lastly, in openSUSE, Bernhard M. Wiedemann published another report for the distribution. There, Bernhard reports about the success of building R-B-OS , a partial fork of openSUSE with only 100% bit-reproducible packages. This effort was sponsored by the NLNet NGI0 initiative.

Upstream patches The Reproducible Builds project detects, dissects and attempts to 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: `cargo-packaging/rusty_v8`, `cockpit`, `collectd`, `deepin-daemon`, `deepin-file-manager`, `esbuild`, `grpc`, `hyperkitty`, `icedtea-web`, `java-atk-wrapper`, `kdenetwork-filesharing`, `kicad`, `kompare`, `librespeed-cli`, `lincity-ng`, `mraa`, `ollama`, `opa-fmgui`, `opencryptoki`, `opencryptoki`, `openmpi4:gnu-hpc`, `openwsman`, `patterns-microos`, `portmidi`, `presage`, `procps`, `sad`, `scons/nst`, `sendmail`, `static-initrd`, `suse-hpc`, `swtpm`, `tiny`, `vtk`, `xdg-desktop-portal` and `yast`.

Chris Lamb:

#1089011 filed against `pyorbital`.

#1089095 filed against `python-pbcore`.

Gioele Barabucci:

#1089088 filed against `sbuild`.

James Addison:

#1090395 filed against `binutils`.

Johannes Schauer Marin Rodrigues:

#1089092 filed against `hurd`.

Moritz Schlarb:

#1090078 filed against `firehol`.

Roland Clobus:

#1090981 filed against `dictionaries-common`.

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 November, a number of changes were made by Holger Levsen, including:

reproduce.debian.net-related:

Add a new `i386.reproduce.debian.net` rebuilder. [ ][ ][ ][ ][ ][ ]

Make a number of updates to the documentation. [ ][ ][ ][ ][ ]

Run `i386.reproduce.debian.net` run on a public port to allow external workers. [ ]

Add a link to the `/api/v0/pkgs/list` endpoint. [ ]

Add support for a statistics page. [ ][ ][ ][ ][ ][ ]

Limit build logs to 20 MiB and diffoscope output to 10 MiB. [ ]

Improve the frontpage. [ ][ ]

Explain that we re testing `arch:any` and `arch:all` on the `amd64` architecture, but only `arch:any` on `i386`. [ ]

Misc:

Freexian Collaborators: Debian Contributions: Tracker.debian.org updates, Salsa CI improvements, Coinstallable build-essential, Python 3.13 transition, Ruby 3.3 transition and more! (by Anupa Ann Joseph, Stefano Rivera)

Debian Contributions: 2024-12 Contributing to Debian is part of Freexian s mission. This article covers the latest achievements of Freexian and their collaborators. All of this is made possible by organizations subscribing to our Long Term Support contracts and consulting services.

Tracker.debian.org updates, by Rapha l Hertzog Profiting from end-of-year vacations, Rapha l prepared for tracker.debian.org to be upgraded to Debian 12 bookworm by getting rid of the remnants of `python3-django-jsonfield` in the code (it was superseded by a Django-native field). Thanks to Philipp Kern from the Debian System Administrators team, the upgrade happened on December 23rd. Rapha l also improved distro-tracker to better deal with invalid `Maintainer` fields which recently caused multiples issues in the regular data updates (#1089985, MR 105). While working on this, he filed #1089648 asking dpkg tools to error out early when maintainers make such mistakes. Finally he provided feedback to multiple issues and merge requests (MR 106, issues #21, #76, #77), there seems to be a surge of interest in distro-tracker lately. It would be nice if those new contributors could stick around and help out with the significant backlog of issues (in the Debian BTS, in Salsa).

Salsa CI improvements, by Santiago Ruano Rinc n Given that the Debian buildd network now relies on sbuild using the unshare backend, and that Salsa CI s reproducibility testing needs to be reworked (#399), Santiago resumed the work for moving the build job to use sbuild. There was some related work a few months ago that was focused on sbuild with the schroot and the sudo backends, but those attempts were stalled for different reasons, including discussions around the convenience of the move (#296). However, using sbuild and unshare avoids all of the drawbacks that have been identified so far. Santiago is preparing two merge requests: !568 to introduce a new build image, and !569 that moves all the extract-source related tasks to the build job. As mentioned in the previous reports, this change will make it possible for more projects to use the pipeline to build the packages (See #195). Additional advantages of this change include a more optimal way to test if a package builds twice in a row: instead of actually building it twice, the Salsa CI pipeline will configure sbuild to check if the clean target of debian/rules correctly restores the source tree, saving some CPU cycles by avoiding one build. Also, the images related to Ubuntu won t be needed anymore, since the build job will create chroots for different distributions and vendors from a single common build image. This will save space in the container registry. More changes are to come, especially those related to handling projects that customize the pipeline and make use of the extract-source job.

Coinstallable `build-essential`, by Helmut Grohne Building on the `gcc-for-host` work of last December, a notable patch turning `build-essential` `Multi-Arch: same` became feasible. Whilst the change is small, its implications and foundations are not. We still install `crossbuild-essential-$ARCH` for cross building and due to a `britney2` limitation, we cannot have it depend on the host s C library. As a result, there are workarounds in place for sbuild and pbuilder. In turning `build-essential` `Multi-Arch: same`, we may actually express these dependencies directly as we install `build-essential:$ARCH` instead. The `crossbuild-essential-$ARCH` packages will continue to be available as transitional dummy packages.

Python 3.13 transition, by Colin Watson and Stefano Rivera Building on last month s work, Colin, Stefano, and other members of the Debian Python team fixed 3.13 compatibility bugs in many more packages, allowing 3.13 to now be a supported but non-default version in testing. The next stage will be to switch to it as the default version, which will start soon. Stefano did some test-rebuilds of packages that only build for the default Python 3 version, to find issues that will block the transition. The default version transition typically shakes out some more issues in applications that (unlike libraries) only test with the default Python version. Colin also fixed Sphinx 8.0 compatibility issues in many packages, which otherwise threatened to get in the way of this transition.

Ruby 3.3 transition, by Lucas Kanashiro The Debian Ruby team decided to ship Ruby 3.3 in the next Debian release, and Lucas took the lead of the interpreter transition with the assistance of the rest of the team. In order to understand the impact of the new interpreter in the ruby ecosystem, ruby-defaults was uploaded to experimental adding ruby3.3 as an alternative interpreter, and a mass rebuild of reverse dependencies was done here. Initially, a couple of hundred packages were failing to build, after many rounds of rebuilds, adjustments, and many uploads we are down to 30 package build failures, of those, 21 packages were asked to be removed from testing and for the other 9, bugs were filled. All the information to track this transition can be found here. Now, we are waiting for PHP 8.4 to finish to avoid any collision. Once it is done the Ruby 3.3 transition will start in unstable.

Miscellaneous contributions

Enrico Zini redesigned the way nm.debian.org stores historical audit logs and personal data backups.

Carles Pina submitted a new package (python-firebase-messaging) and prepared updates for python3-ring-doorbell.

Carles Pina developed further po-debconf-manager: better state transition, fixed bugs, automated assigning translators and reviewers on edit, updating po header files automatically, fixed bugs, etc.

Carles Pina reviewed, submitted and followed up the debconf templates translation (more than 20 packages) and translated some packages (about 5).

Santiago continued to work on DebConf 25 organization related tasks, including handling the logo survey and results. Stefano spent time on DebConf 25 too.

Santiago continued the exploratory work about linux livepatching with Emmanuel Arias. Santiago and Emmanuel found a challenge since kpatch won t fully support linux in trixie and newer, so they are exploring alternatives such as klp-build.

Helmut maintained the /usr-move transition filing bugs in e.g. `bubblewrap`, `e2fsprogs`, `libvpd-2.2-3`, and `pam-tmpdir` and corresponding on related issues such as `kexec-tools` and `live-build`. The removal of the `usrmerge` package unfortunately broke `debootstrap` and was quickly reverted. Continued fallout is expected and will continue until `trixie` is released.

Helmut sent patches for 10 cross build failures and worked with Sandro Knau on stuck Qt/KDE patches related to cross building.

Helmut continued to maintain rebootstrap removing the need to build `gnu-efi` in the process.

Helmut collaborated with Emanuele Rocca and Jochen Sprickerhof on an interesting adventure in diagnosing why gcc would FTBFS in recent sbuild.

Helmut proposed supporting build concurrency limits in coreutils s nproc. As it turns out `nproc` is not a good place for this functionality.

Colin worked with Sandro Tosi and Andrej Shadura to finish resolving the multipart vs. python-multipart name conflict, as mentioned last month.

Colin upgraded 48 Python packages to new upstream versions, fixing four CVEs and a number of compatibility bugs with recent Python versions.

Colin issued an openssh bookworm update with a number of fixes that had accumulated over the last year, especially fixing GSS-API key exchange which had been quite broken in bookworm.

Stefano fixed a minor bug in debian-reimbursements that was disallowing combination PDFs containing JAL tickets, encoded in UTF-16.

Stefano uploaded a stable update to PyPy3 in bookworm, catching up with security issues resolved in cPython.

Stefano fixed a regression in the eventlet from his Python 3.13 porting patch.

Stefano continued discussing a forwarded patch (renaming the sysconfigdata module) with cPython upstream, ending in a decision to drop the patch from Debian. This will need some continued work.

Anupa participated in the Debian Publicity team meeting in December, which discussed the team activities done in 2024 and projects for 2025.

John Goerzen: Censorship Is Complicated: What Internet History Says about Meta/Facebook

In light of this week s announcement by Meta (Facebook, Instagram, Threads, etc), I have been pondering this question: Why am I, a person that has long been a staunch advocate of free speech and encryption, leery of sites that talk about being free speech-oriented? And, more to the point, why an I a person that has been censored by Facebook for mentioning the Open Source social network Mastodon not cheering a lighter touch ? The answers are complicated, and take me back to the early days of social networking. Yes, I mean the 1980s and 1990s. Before digital communications, there were barriers to reaching a lot of people. Especially money. This led to a sort of self-censorship: it may be legal to write certain things, but would a newspaper publish a letter to the editor containing expletives? Probably not. As digital communications started to happen, suddenly people could have their own communities. Not just free from the same kinds of monetary pressures, but free from outside oversight (parents, teachers, peers, community, etc.) When you have a community that the majority of people lack the equipment to access and wouldn t understand how to access even if they had the equipment you have a place where self-expression can be unleashed. And, as J. C. Herz covers in what is now an unintentional history (her book Surfing on the Internet was published in 1995), self-expression WAS unleashed. She enjoyed the wit and expression of everything from odd corners of Usenet to the text-based open world of MOOs and MUDs. She even talks about groups dedicated to insults (flaming) in positive terms. But as I ve seen time and again, if there are absolutely no rules, then whenever a group gets big enough more than a few dozen people, say there are troublemakers that ruin it for everyone. Maybe it s trolling, maybe it s vicious attacks, you name it it will arrive and it will be poisonous. I remember the debates within the Debian community about this. Debian is one of the pillars of the Internet today, a nonprofit project with free speech in its DNA. And yet there were inevitably the poisonous people. Debian took too long to learn that allowing those people to run rampant was causing more harm than good, because having a well-worn Delete key and a tolerance for insults became a requirement for being a Debian developer, and that drove away people that had no desire to deal with such things. (I should note that Debian strikes a much better balance today.) But in reality, there were never absolutely no rules. If you joined a BBS, you used it at the whim of the owner (the sysop or system operator). The sysop may be a 16-yr-old running it from their bedroom, or a retired programmer, but in any case they were letting you use their resources for free and they could kick you off for any or no reason at all. So if you caused trouble, or perhaps insulted their cat, you re banned. But, in all but the smallest towns, there were other options you could try. On the other hand, sysops enjoyed having people call their BBSs and didn t want to drive everyone off, so there was a natural balance at play. As networks like Fidonet developed, a sort of uneasy approach kicked in: don t be excessively annoying, and don t be easily annoyed. Like it or not, it seemed to generally work. A BBS that repeatedly failed to deal with troublemakers could risk removal from Fidonet. On the more institutional Usenet, you generally got access through your university (or, in a few cases, employer). Most universities didn t really even know they were running a Usenet server, and you were generally left alone. Until you did something that annoyed somebody enough that they tracked down the phone number for your dean, in which case real-world consequences would kick in. A site may face the Usenet Death Penalty delinking from the network if they repeatedly failed to prevent malicious content from flowing through their site. Some BBSs let people from minority communities such as LGBTQ+ thrive in a place of peace from tormentors. A lot of them let people be themselves in a way they couldn t be in real life . And yes, some harbored trolls and flamers. The point I am trying to make here is that each BBS, or Usenet site, set their own policies about what their own users could do. These had to be harmonized to a certain extent with the global community, but in a certain sense, with BBSs especially, you could just use a different one if you didn t like what the vibe was at a certain place. That this free speech ethos survived was never inevitable. There were many attempts to regulate the Internet, and it was thanks to the advocacy of groups like the EFF that we have things like strong encryption and a degree of freedom online. With the rise of the very large platforms and here I mean CompuServe and AOL at first, and then Facebook, Twitter, and the like later the low-friction option of just choosing a different place started to decline. You could participate on a Fidonet forum from any of thousands of BBSs, but you could only participate in an AOL forum from AOL. The same goes for Facebook, Twitter, and so forth. Not only that, but as social media became conceived of as very large sites, it became impossible for a person with enough skill, funds, and time to just start a site themselves. Instead of neading a few thousand dollars of equipment, you d need tens or hundreds of millions of dollars of equipment and employees. All that means you can t really run Facebook as a nonprofit. It is a business. It should be absolutely clear to everyone that Facebook s mission is not the one they say it is [to] give people the power to build community and bring the world closer together. If that was their goal, they wouldn t be creating AI users and AI spam and all the rest. Zuck isn t showing courage; he s sucking up to Trump and those that will pay the price are those that always do: women and minorities. Really, the point of any large social network isn t to build community. It s to make the owners their next billion. They do that by convincing people to look at ads on their site. Zuck is as much a windsock as anyone else; he will adjust policies in whichever direction he thinks the wind is blowing so as to let him keep putting ads in front of eyeballs, and stomp all over principles even free speech doing it. Don t expect anything different from any large commercial social network either. Bluesky is going to follow the same trajectory as all the others. The problem with a one-size-fits-all content policy is that the world isn t that kind of place. For instance, I am a pacifist. There is a place for a group where pacifists can hang out with each other, free from the noise of the debate about pacifism. And there is a place for the debate. Forcing everyone that signs up for the conversation to sign up for the debate is harmful. Preventing the debate is often also harmful. One company can t square this circle. Beyond that, the fact that we care so much about one company is a problem on two levels. First, it indicates how succeptible people are to misinformation and such. I don t have much to offer on that point. Secondly, it indicates that we are too centralized. We have a solution there: Mastodon. Mastodon is a modern, open source, decentralized social network. You can join any instance, easily migrate your account from one server to another, and so forth. You pick an instance that suits you. There are thousands of others you can choose from. Some aggressively defederate with instances known to harbor poisonous people; some don t. And, to harken back to the BBS era, if you have some time, some skill, and a few bucks, you can run your own Mastodon instance. Personally, I still visit Facebook on occasion because some people I care about are mainly there. But it is such a terrible experience that I rarely do. Meta is becoming irrelevant to me. They are on a path to becoming irrelevant to many more as well. Maybe this is the moment to go shrug, this sucks and try something better. (And when you do, feel free to say hi to me at @jgoerzen@floss.social on Mastodon.)

Jonathan Wiltshire: Using TPM for Automatic Disk Decryption in Debian 12

These days it s straightforward to have reasonably secure, automatic decryption of your root filesystem at boot time on Debian 12. Here s how I did it on an existing system which already had a stock kernel, secure boot enabled, grub2 and an encrypted root filesystem with the passphrase in key slot 0. There s no need to switch to systemd-boot for this setup but you will use systemd-cryptenroll to manage the TPM-sealed key. If that offends you, there are other ways of doing this.

Caveat The parameters I ll seal a key against in the TPM include a hash of the initial ramdisk. This is essential to prevent an attacker from swapping the image for one which discloses the key. However, it also means the key has to be re-sealed every time the image is rebuilt. This can be frequent, for example when installing/upgrading/removing packages which include a kernel module. You won t get locked out (as long as you still have a passphrase in another slot), but will need to re-seal the key to restore the automation. You can also choose not to include this parameter for the seal, but that opens the door to such an attack.
Caution: these are the steps I took on my own system. You may need to adjust them to avoid ending up with a non-booting system.

Check for a usable TPM device We ll bind the secure boot state, kernel parameters, and other boot measurements to a decryption key. Then, we ll seal it using the TPM. This prevents the disk being moved to another system, the boot chain being tampered with and various other attacks.

# apt install tpm2-tools
# systemd-cryptenroll --tpm2-device list
PATH        DEVICE     DRIVER 
/dev/tpmrm0 STM0125:00 tpm_tis

Clean up older kernels including leftover configurations I found that previously-removed (but not purged) kernel packages sometimes cause dracut to try installing files to the wrong paths. Identify them with:

# apt install aptitude
# aptitude search '~c'

Change search to purge or be more selective, this part is an exercise for the reader.

Switch to dracut for initramfs images Unless you have a particular requirement for the default initramfs-tools, replace it with dracut and customise:

# mkdir /etc/dracut.conf.d
# echo 'add_dracutmodules+=" tpm2-tss crypt "' > /etc/dracut.conf.d/crypt.conf
# apt install dracut

Remove root device from `crypttab`, configure `grub` Remove (or comment) the root device from `/etc/crypttab` and rebuild the initial ramdisk with `dracut -f`. Edit `/etc/default/grub` and add `rd.auto rd.luks=1` to `GRUB_CMDLINE_LINUX`. Re-generate the config with `update-grub`. At this point it s a good idea to sanity-check the initrd contents with `lsinitrd`. Then, reboot using the new image to ensure there are no issues. This will also have up-to-date TPM measurements ready for the next step.

Identify device and seal a decryption key

# lsblk -ip -o NAME,TYPE,MOUNTPOINTS
NAME                                                    TYPE  MOUNTPOINTS
/dev/nvme0n1p4                                          part  /boot
/dev/nvme0n1p5                                          part  
 -/dev/mapper/luks-deff56a9-8f00-4337-b34a-0dcda772e326 crypt 
   -/dev/mapper/lv-var                                  lvm   /var
   -/dev/mapper/lv-root                                 lvm   /
   -/dev/mapper/lv-home                                 lvm   /home

In this example my root filesystem is in a container on /dev/nvme0n1p5. The existing passphrase key is in slot 0.

# systemd-cryptenroll --tpm2-device=auto --tpm2-pcrs=7+8+9+14 /dev/nvme0n1p5
Please enter current passphrase for disk /dev/nvme0n1p5: ********
New TPM2 token enrolled as key slot 1.

The PCRs I chose (7, 8, 9 and 14) correspond to the secure boot policy, kernel command line (to prevent init=/bin/bash-style attacks), files read by grub including that crucial initrd measurement, and secure boot MOK certificates and hashes. You could also include PCR 5 for the partition table state, and any others appropriate for your setup.

Reboot You should now be able to reboot and the root device will be unlocked automatically, provided the secure boot measurements remain consistent. The key slot protected by a passphrase (mine is slot 0) is now your recovery key. Do not remove it!

Thorsten Alteholz: My Debian Activities in December 2024

Debian LTS This was my hundred-twenty-sixth month that I did some work for the Debian LTS initiative, started by Raphael Hertzog at Freexian. I worked on updates for ffmpeg and haproxy in all releases. Along the way I marked more CVEs as not-affected than I had to fix. So finally there was no upload needed for haproxy anymore. Unfortunately testing ffmpeg was not as easy, as the recommended just look whether mpv can play random videos is not really satisfying. So the upload will happen only in January. I also wonder whether fixing glewlwyd is really worth the effort, as the software is already EOL upstream. Debian ELTS This month was the seventy-seventhth ELTS month. During my allocated time I worked on ffmpeg, haproxy, amanda and kmail-account-wizzard. Like LTS, all CVEs of haproxy and some of ffmpeg could be marked as not-affected and testing of the other packages was/is not really straight forward. So the final upload will only happen in January as well. Debian Printing Unfortunately I didn t found any time to work on this topic. Debian Matomo Thanks a lot to William Desportes for all fixes of my bad PHP packaging. Debian Astro This month I uploaded new packages or new upstream or bugfix versions of:

astronomical-almanac to add CI, gbp.conf and fix a bug

I again sponsored an upload of calceph. Debian IoT This month I uploaded new upstream or bugfix versions of: Debian Mobcom This month I uploaded new packages or new upstream or bugfix versions of:

libosmo-analog (package prepared by Nathan)
osmo-tetra (package prepared by Nathan)
libosmo-sccp
osmo-libasn1c

misc This month I uploaded new upstream or bugfix versions of:

I also sponsored uploads of emacs-lsp-docker, emacs-dape, emacs-oauth2, gpgmngr, libjs-jush. FTP master This month I accepted 330 and rejected 13 packages. The overall number of packages that got accepted was 335.

Jonathan McDowell: Free Software Activities for 2024

I tailed off on blog posts towards the end of the year; I blame a bunch of travel (personal + business), catching the flu, then December being its usual busy self. Anyway, to try and start off the year a bit better I thought I d do my annual recap of my Free Software activities. For previous years see 2019, 2020, 2021, 2022 + 2023.

Conferences In 2024 I managed to make it to FOSDEM again. It s a hectic conference, and I know there are legitimate concerns about it being a super spreader event, but it has the advantage of being relatively close and having a lot of different groups of people I want to talk to / see talk at it. I m already booked to go this year as well. I spoke at All Systems Go in Berlin about Using TPMs at scale for protecting keys. It was nice to actually be able to talk publicly about some of the work stuff my team and I have been working on. I d a talk submission in for FOSDEM about our use of attestation and why it s not necessarily the evil some folk claim, but there were a lot of good talks submitted and I wasn t selected. Maybe I ll find somewhere else suitable to do it. BSides Belfast may or may not count - it s a security conference, but there s a lot of overlap with various bits of Free software, so I feel it deserves a mention. I skipped DebConf for 2024 for a variety of reasons, but I m expecting to make DebConf25 in Brest, France in July.

Debian Most of my contributions to Free software continue to happen within Debian. In 2023 I d done a bunch of work on retrogaming with Kodi on Debian, so I made an effort to try and keep those bits more up to date, even if I m not actually regularly using them at present. RetroArch got 1.18.0+dfsg-1 and 1.19.1+dfsg-1 uploads. libretro-core-info got associated 1.18.0-1 and 1.19.0-1 uploads too. I note 1.20.0 has been released recently, so I ll have to find some time to build the appropriate DFSG tarball and update it. rcheevos saw 11.2.0-1, 11.5.0-1 + 11.6.0-1 uploaded. kodi-game-libretro itself had 20.2.7-1 uploaded, then 21.0.7-1. Latest upstream is 22.1.0, but that s tracking Kodi 22 and we re still on Kodi 21 so I plan to follow the Omega branch for now. Which I ve just noticed had a 21.0.8 release this week. Finally in the games space I uploaded mgba 0.10.3+dfsg-1 and 0.10.3+dfsg-2 for Ryan Tandy, before realising he was already a Debian Maintainer and granting him the appropriate ACL access so he can upload it himself; I ve had zero concerns about any of his packaging. The Debian Electronics Packaging Team continues to be home for a bunch of packages I care about. There was nothing big there, for me, in 2024, but a few bits of cleanup here and there. I seem to have become one of the main uploaders for sdcc - I have some interest in the space, and the sigrok firmware requires it to build, so I at least like to ensure it s in half decent state. I uploaded 4.4.0+dfsg-1, 4.4.0+dfsg-2, and, just in time to count for 2024, 4.4.0+dfsg-3. The sdcc 4.4 upload lead to some compilation issues for sigrok-firmware-fx2laf so I uploaded 0.1.7-2 fixing that, then 0.1.7-3 doing some further cleanups. OpenOCD had 0.12.0-2 uploaded to disable the libgpiod backend thanks to incompatible changes upstream. There were some in-discussion patches with OpenOCD upstream at the time, but they didn t seem to be ready yet so I held off on pulling them in. 0.12.0-3 fixed builds with more recent versions of jimtcl. It looks like the next upstream release is about a year away, so Trixie will in all probability ship with 0.12.0 as well. libjaylink had a new upstream release, so 0.4.0-1 was uploaded. libserialsport also had a new upstream release, leading to 0.1.2-1. I finally cracked and uploaded sg3-utils 1.48-1 into experimental. I m not the primary maintainer, but 1.46 is nearly 4 years old now and I wanted to get it updated in enough time to shake out any problems before we get to a Trixie freeze. Outside of team owned packages, libcli had compilation issues with GCC 14, leading to 1.10.7-2. I also added a new package, sedutil 1.20.0-2 back in April; it looks fairly unmaintained upstream (there s been some recent activity, but it doesn t seem to be release quality), but there was an outstanding ITP and I ve some familiarity with the space as we ve been using it at work as part of investigating TCG OPAL encryption. I continue to keep an eye on Debian New Members, even though I m mostly inactive as an application manager - we generally seem to have enough available recently. Mostly my involvement is via Front Desk activities, helping out with queries to the team alias, and contributing to internal discussions. Finally the 3 month rotation for Debian Keyring continues to operate smoothly. I dealt with 2023.03.24, 2023.06.24, 2023.09.22 + 2023.11.24.

Linux I d a single kernel contribution this year, to Clean up TPM space after command failure. That was based on some issues we saw at work. I ve another fix in progress that I hope to submit in 2025, but it s for an intermittent failure so confirming the fix is necessary + sufficient is taking a little while.

Personal projects I didn t end up doing much in the way of externally published personal project work in 2024. Despite the release of OpenPGP v6 in RFC 9580 I did not manage to really work on onak. I started on the v6 support, but have not had sufficient time to complete anything worth pushing external yet. listadmin3 got some minor updates based on external feedback / MRs. It s nice to know it s useful to other folk even in its basic state. That wraps up 2024. I ve got no particular goals for this year at present. Ideally I d get v6 support into onak, and it would be nice to implement some of the wishlist items people have provided for listadmin3, but I ll settle for making sure all my Debian packages are in reasonable state for Trixie.

Kentaro Hayashi: Tips when building debian-installer

Recently, I'm trying to fix d-i Han-Unification issue for Japanese. This issue was not fixed for a long time since Debian 9 (stretch). #1037256 - debian-installer: GUI font for Japanese was incorrectly rendered - Debian Bug report logs

To know about how Han-Unification is harmful for Japanese in some cases, See "Your Code Displays Japanese Wrong". heistak.github.io

When building d-i (GUI Installer), you need to build build_netboot-gtk target. But note that you need recent master because it has nitpick issue with GNU Make 4.4.x. bugs.debian.org After that, need to prepare required packages. See README in details.

apt-get update
apt-get install -y myrepos git libgtk2.0-dev fakeroot
apt-get build-dep -y debian-installer

It seems that Bug#1037256 will be fixed with supporting compressed font. I don't know how to do it furthermore , but I'm sure that Mr. Cyril Brulebois will handle this issue better. :-) (I thought that creating fake fontconfig cache when building image, then decompress compressed font dynamically might work as just an idea, but it didn't work.) If you would like to tackle fixing d-i issues as a newbie, it might be better to execute "make reallyclean" before rebuilding image not to fall-in pitfalls.

Bits from Debian: Bits from the DPL

Dear Debian community, this is bits from DPL for December. Happy New Year 2025! Wishing everyone health, productivity, and a successful Debian release later in this year. Strict ownership of packages I'm glad my last bits sparked discussions about barriers between packages and contributors, summarized temporarily in some post on the debian-devel list. As one participant aptly put it, we need a way to visibly say, "I'll do the job until someone else steps up". Based on my experience with the Bug of the Day initiative, simplifying the process for engaging with packages would significantly help. Currently we have

NMU The Developers Reference outlines several preconditions for NMUs, explicitly stating, "Fixing cosmetic issues or changing the packaging style in NMUs is discouraged." This makes NMUs unsuitable for addressing package smells. However, I've seen NMUs used for tasks like switching to source format 3.0 or bumping the debhelper compat level. While it's technically possible to file a bug and then address it in an NMU, the process inherently limits the NMUer's flexibility to reduce package smells.
Package Salvaging This is another approach for working on someone else's packages, aligning with the process we often follow in the Bug of the Day initiative. The criteria for selecting packages typically indicate that the maintainer either lacks time to address open bugs, has lost interest, or is generally MIA.

Both options have drawbacks, so I'd welcome continued discussion on criteria for lowering the barriers to moving packages to Salsa and modernizing their packaging. These steps could enhance Debian overall and are generally welcomed by active maintainers. The discussion also highlighted that packages on Salsa are often maintained collaboratively, fostering the team-oriented atmosphere already established in several Debian teams. Salsa Continuous Integration As part of the ongoing discussion about package maintenance, I'm considering the suggestion to switch from the current opt-in model for Salsa CI to an opt-out approach. While I fully agree that human verification is necessary when the pipeline is activated, I believe the current option to enable CI is less visible than it should be. I'd welcome a more straightforward approach to improve access to better testing for what we push to Salsa. Number of packages not on Salsa In my campaign, I stated that I aimed to reduce the number of packages maintained outside Salsa to below 2,000. As of March 28, 2024, the count was 2,368. As of this writing, the count stands at 1,928 [1], so I consider this promise fulfilled. My thanks go out to everyone who contributed to this effort. Moving forward, I'd like to set a more ambitious goal for the remainder of my term and hope we can reduce the number to below 1,800. [1] UDD query: SELECT DISTINCT count(*) FROM sources WHERE release = 'sid' and vcs_url not like '%salsa%' ; Past and future events Talk at MRI Together In early December, I gave a short online talk, primarily focusing on my work with the Debian Med team. I also used my position as DPL to advocate for attracting more users and developers from the scientific research community. FOSSASIA I originally planned to attend FOSDEM this year. However, given the strong Debian presence there and the need for better representation at the FOSSASIA Summit, I decided to prioritize the latter. This aligns with my goal of improving geographic diversity. I also look forward to opportunities for inter-distribution discussions. Debian team sprints Debian Ruby Sprint I approved the budget for the Debian Ruby Sprint, scheduled for January 2025 in Paris. If you're interested in contributing to the Ruby team, whether in person or online, consider reaching out to them. I'm sure any helping hand would be appreciated. Debian Med sprint There will also be a Debian Med sprint in Berlin in mid-February. As usual, you don't need to be an expert in biology or medicine basic bug squashing skills are enough to contribute and enjoy the friendly atmosphere the Debian Med team fosters at their sprints. For those working in biology and medicine, we typically offer packaging support. Anyone interested in spending a weekend focused on impactful scientific work with Debian is warmly invited. Again all the best for 2025

Andreas.
