Marco d'Itri: CISPE's call for new regulations on VMware

A few days ago CISPE, a trade association of European cloud providers, published a press release complaining about the new VMware licensing scheme and asking for regulators and legislators to intervene. But VMware does not have a monopoly on virtualization software: I think that asking regulators to interfere is unnecessary and unwise, unless, of course, they wish to question the entire foundations of copyright. Which, on the other hand, could be an intriguing position that I would support... I believe that over-reliance on a single supplier is a typical enterprise risk: in the past decade some companies have invested in developing their own virtualization infrastructure using free software, while others have decided to rely entirely on a single proprietary software vendor. My only big concern is that many public sector organizations will continue to use VMware and pay the huge fees designed by Broadcom to extract the maximum amount of money from their customers. However, it is ultimately the citizens who pay these bills, and blaming the evil US corporation is a great way to avoid taking responsibility for these choices.
"Several CISPE members have stated that without the ability to license and use VMware products they will quickly go bankrupt and out of business."
Insert here the Jeremy Clarkson "Oh no! Anyway..." meme.

Marco d'Itri: Extending access to the systemd RuntimeDirectory with a POSIX ACL

inn2 uses ephemeral UNIX domain sockets in /run/news/ to communicate with the ctlinnd program. Since the directory is only writeable by the "news" user, other unprivileged users are not able to use the command. I solved this by extending the inn2.service systemd unit with a drop-in file which uses setfacl to give access to my user "md" to the RuntimeDirectory created by systemd. This is the content of /etc/systemd/system/inn2.service.d/md-ctlinnd.conf: 
[Service]
# innd will change the permissions of /run/news/ when started: without
# creating it now with mode 0775 then that will change the ACL mask.
RuntimeDirectoryMode=0775
# allow user md to run ctlinnd(8), which creates sockets in /run/news/
ExecStartPost=/usr/bin/setfacl --modify user:md:rwx $RUNTIME_DIRECTORY
The non-obvious issue here is that the innd daemon on startup will change the directory permissions in a way which sets a more restrictive (non group-writeable) ACL mask, and this would make the newly created user ACL ineffective. The solution is to create the directory group-writeable from start. (Beware: this creates a trivial privileges escalation from md to news.)

Freexian Collaborators: Debian Contributions: Upcoming Improvements to Salsa CI, /usr-move, and more! (by Utkarsh Gupta)

Upcoming Improvements to Salsa CI, by Santiago Ruano Rinc n Santiago started picking up the work made by Outreachy Intern, Enock Kashada (a big thanks to him!), to solve some long-standing issues in Salsa CI. Currently, the first job in a Salsa CI pipeline is the extract-source job, used to produce a debianize source tree of the project. This job was introduced to make it possible to build the projects on different architectures, on the subsequent build jobs. However, that extract-source approach is sub-optimal: not only it increases the execution time of the pipeline by some minutes, but also projects whose source tree is too large are not able to use the pipeline. The debianize source tree is passed as an artifact to the build jobs, and for those large projects, the size of their source tree exceeds the Salsa s limits. This is specific issue is documented as issue #195, and the proposed solution is to get rid of the extract-source job, relying on sbuild in the very build job (see issue #296). Switching to sbuild would also help to improve the build source job, solving issues such as #187 and #298. The current work-in-progress is very preliminary, but it has already been possible to run the build (amd64), build-i386 and build-source job using sbuild with the unshare mode. The image on the right shows a pipeline that builds grep. All the test jobs use the artifacts of the new build job. There is a lot of remaining work, mainly making the integration with ccache work. This change could break some things, it will also be important to test how the new pipeline works with complex projects. Also, thanks to Emmanuel Arias, we are proposing a Google Summer of Code 2024 project to improve Salsa CI. As part of the ongoing work in preparation for the GSoC 2024 project, Santiago has proposed a merge request to make more efficient how contributors can test their changes on the Salsa CI pipeline.

/usr-move, by Helmut Grohne In January, we sent most of the moving patches for the set of packages involved with debootstrap. Notably missing is glibc, which turns out harder than anticipated via dumat, because it has Conflicts between different architectures, which dumat does not analyze. Patches for diversion mitigations have been updated in a way to not exhibit any loss anymore. The main change here is that packages which are being diverted now support the diverting packages in transitioning their diversions. We also supported a few packages with non-trivial changes such as netplan.io. dumat has been enhanced to better support derivatives such as Ubuntu.

Miscellaneous contributions
  • Python 3.12 migration trundles on. Stefano Rivera helped port several new packages to support 3.12.
  • Stefano updated the Sphinx configuration of DebConf Video Team s documentation, which was broken by Sphinx 7.
  • Stefano published the videos from the Cambridge MiniDebConf to YouTube and PeerTube.
  • DebConf 24 planning has begun, and Stefano & Utkarsh have started work on this.
  • Utkarsh re-sponsored the upload of golang-github-prometheus-community-pgbouncer-exporter for Lena.
  • Colin Watson added Incus support to autopkgtest.
  • Colin discovered Perl::Critic and used it to tidy up some poor practices in several of his packages, including debconf.
  • Colin did some overdue debconf maintenance, mainly around tidying up error message handling in several places (1, 2, 3).
  • Colin figured out how to update the mirror size documentation in debmirror, last updated in 2010. It should now be much easier to keep it up to date regularly.
  • Colin issued a man-db buster update to clean up some irritations due to strict sandboxing.
  • Thorsten Alteholz adopted two more packages, magicfilter and ifhp, for the debian-printing team. Those packages are the last ones of the latest round of adoptions to preserve the old printing protocol within Debian. If you know of other packages that should be retained, please don t hesitate to contact Thorsten.
  • Enrico participated in /usr-merge discussions with Helmut.
  • Helmut sent patches for 16 cross build failures.
  • Helmut supported Matthias Klose (not affiliated with Freexian) with adding -for-host support to gcc-defaults.
  • Helmut uploaded dput-ng enabling dcut migrate and merging two MRs of Ben Hutchings.
  • Santiago took part in the discussions relating to the EU Cyber Resilience Act (CRA) and the Debian public statement that was published last year. He participated in a meeting with Members of the European Parliament (MEPs), Marcel Kolaja and Karen Melchior, and their teams to clarify some points about the impact of the CRA and Debian and downstream projects, and the improvements in the last version of the proposed regulation.

Thorsten Alteholz: My Debian Activities in January 2024

FTP master This month I accepted 333 and rejected 31 packages. The overall number of packages that got accepted was 342.

Hooray, I already accepted package number 30000.

The statistic, where I get my numbers from, started in February 2002. Up to now 81694 packages got accepted. Given that I accepted package 20000 in October 2020, would I be able to accept half of the packages that made it through NEW? Debian LTS This was my hundred-fifteenth month that I did some work for the Debian LTS initiative, started by Raphael Hertzog at Freexian. During my allocated time I uploaded: This month I was finally able to really run the test suite of bind9. I already wanted to give up with this package, but Santiago encouraged me to proceed. So, here you are fixed-Buster-version. Jessie and Stretch have to wait a bit until the dust has settled. Last but not least I also did a few days of frontdesk duties. Debian ELTS This month was the sixty-sixth ELTS month. During my allocated time I uploaded: This month I also worked on the Jessie and Stretch updates for bind9. The uploads should happen soon. I also started to work on an update for exim4. Last but not least I did a few days of frontdesk duties. Debian Printing This month I adopted: At the moment these packages are the last adoptions to preserve the old printing protocol within Debian. If you know of other packages that should be retained, please don t hesitate to ask me. But don t wait for too long, I have fun to process RM-bugs :-). This work is generously funded by Freexian! Debian Astro This month I uploaded a new upstream version of: Debian IoT This month I uploaded new upstream versions of: Other stuff This month I uploaded new upstream version of packages, did a source upload for the transition or uploaded it to fix one or the other issue:

Freexian Collaborators: Debian Contributions: LXD/Incus backend bug, /usr-merge updates, gcc-for-host, and more! (by Utkarsh Gupta)

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.

LXD/Incus backend bug in autopkgtest by Stefano Rivera While working on the Python 3.12 transition, Stefano repeatedly ran into a bug in autopkgtest when using LXD (or in the future Incus), that caused it to hang when running cython s multi-hour autopkgtests. After some head-banging, the bug turned out to be fairly straightforward: LXD didn t shut down on receiving a SIGTERM, so when a testsuite timed out, it would hang forever. A simple fix has been applied.

/usr-merge, by Helmut Grohne Thanks to Christian Hofstaedtler and others, the effort is moving into a community effort and the work funded by Freexian becomes more difficult to separate from non-funded work. In particular, since the community fully handled all issues around lost udev rules, dh_installudev now installs rules to /usr. The story around diversions took another detour. We learned that conflicts do not reliably prevent concurrent unpack and the reiterated mitigation for molly-guard triggered this. After a bit of back and forth and consultation with the developer mailing list, we concluded that avoiding the problematic behavior when using apt or an apt-based upgrader combined with a loss mitigation would be good enough. The involved packages bfh-container, molly-guard, progress-linux-container and systemd have since been uploaded to unstable and the matter seems finally solved except that it doesn t quite work with sysvinit yet. The same approach is now being proposed for the diversions of zutils for gzip. We thank involved maintainers for their timely cooperation.

gcc-for-host, by Helmut Grohne Since forever, it has been difficult to correctly express a toolchain build dependency. This can be seen in the Build-Depends of the linux source package for instance. While this has been solved for binutils a while back, the patches for gcc have been unfinished. With lots of constructive feedback from gcc package maintainer Matthias Klose, Helmut worked on finalizing and testing these patches. Patch stacks are now available for gcc-13 and gcc-14 and Matthias already included parts of them in test builds for Ubuntu noble. Finishing this work would enable us to resolve around 1000 cross build dependency satisfiability issues in unstable.

Miscellaneous contributions
  • Stefano continued work on the Python 3.12 transition, including uploads of cython, pycxx, numpy, python-greenlet, twisted, foolscap and dh-python.
  • Stefano reviewed and selected from a new round of DebConf 24 bids, as part of the DebConf Committee. Busan, South Korea was selected.
  • For debian-printing Thorsten uploaded hplip to unstable to fix a /usr-merge bug and cups to Bookworm to fix bugs related to printing in color.
  • Utkarsh helped newcomers in mentoring and reviewing their packaging; eg: golang-github-prometheus-community-pgbouncer-exporter.
  • Helmut sent patches for 42 cross build failures unrelated to the gcc-for-host work.
  • Helmut continues to maintain rebootstrap. In December, blt started depending on libjpeg and this poses a dependency loop. Ideally, Python would stop depending on blt. Also linux-libc-dev having become Multi-Arch: foreign poses non-trivial issues that are not fully resolved yet.
  • Enrico participated in /usr-merge discussions with Helmut.

Valhalla's Things: Random Sashiko + Crazy Quilt Pocket

Posted on January 5, 2024
Tags: madeof:atoms
A 18th century pocket in black jeans with a random pattern of pink running stitches forming squares and other shapes. The unfinished edges of the pieces of jeans can be seen, running more or less diagonally. Lately I ve seen people on the internet talking about victorian crazy quilting. Years ago I had watched a Numberphile video about Hitomezashi Stitch Patterns based on numbers, words or randomness. Few weeks ago I had cut some fabric piece out of an old pair of jeans and I had a lot of scraps that were too small to do anything useful on their own. It easy to see where this can go, right? The wrong side of a pocket piece, showing a light coloured fabric with a grid drawn in pencil, a line of small stitches all around the edges and a mess of thread ends left hanging. I cut a pocket shape out of old garment mockups (this required some piecing), drew a square grid, arranged scraps of jeans to cover the other side, kept everything together with a lot of pins, carefully avoided basting anything, and started covering everything in sashiko / hitomezashi stitches, starting each line with a stitch on the front or the back of the work based on the result of: 
import random
random.choice(["front", "back"])
The wrong side of the other pocket piece, with just three lines of stitching and a piece of paper to mark the pattern. There are bits of jeans peeking out of the sides. For the second piece I tried to use a piece of paper with the square grid instead of drawing it on the fabric: it worked, mostly, I would not do it again as removing the paper was more of a hassle than drawing the lines in the first place. I suspected it, but had to try it anyway. The front of the pocket seen from the wrong side, with a machine seam around the lit, whose end has been cut in a triangle so that it can be turned. Then I added a lining from some plain black cotton from the stash; for the slit I put the lining on the front right sides together, sewn at 2 mm from the marked slit, cut it, turned the lining to the back side, pressed and then topstitched as close as possible to the slit from the front. The finished pocket attached to a belt made from the waistband of a pair of jeans (with button, buttonhole and belt loops still attached) whose raw edges (left when unpicking away the jeans) have been sewn shut by hand. I bound everything with bias tape, adding herringbone tape loops at the top to hang it from a belt (such as one made from the waistband of one of the donor pair of jeans) and that was it. The back of the pocket, showing another random pattern in two different shades of pink for the vertical and horizontal lines of stitching. I like the way the result feels; maybe it s a bit too stiff for a pocket, but I can see it work very well for a bigger bag, and maybe even a jacket or some other outer garment.

Russ Allbery: Review: The Blackwing War

Review: The Blackwing War, by K.B. Spangler
Series: Deep Witches #1
Publisher: A Girl and Her Fed Books
Copyright: March 2021
ISBN: blackwing-war
Format: Kindle
Pages: 284
The Blackwing War is the first book of a projected space opera series. I previously reviewed Stoneskin, which was intended as a prelude to this series. In theory you can start here, but I would read Stoneskin first. Tembi is a Witch, which means she can ask the Deep to do things for her. At the start of the book, those things mostly involve disarming bombs. The galaxy is in the middle of a genocidal war between the well-equipped and all-but-officially supported Sagittarius Armed Forces, also known as the Blackwings, and the Sabenta resistance movement. To settle the galaxy, humans fiddled with their genes to adapt themselves to otherwise-hostile planets. The Blackwings take exception, in the tradition of racist humans throughout history, and think it's time to purify human bloodlines again. Both sides are using bombs. The Deep is the brilliant idea of this series. It seems to exist everywhere simultaneously, it's alive, it adores teleporting things, and it's basically a giant cosmic puppy. Humans are nearly incomprehensible to the Deep, and it's nearly incomprehensible to humans, but it somehow picks out specific humans who can (sort of) understand it and whom it gets attached to and somehow makes immortal. These are the Witches, and they have turned the Deep into the logistical backbone of human civilization. Essentially all commerce and travel is now done through Deep teleportation, requested by a Witch and coordinated by Lancaster, the Witches' governing council. The exception is war. Lancaster is strictly neutral; it does not take sides, even in the face of an ongoing genocide, and it refuses to transport military ships, any type of weapons, or even war refugees. Domino, Lancaster's cynically manipulative leader, is determined to protect its special privileges and position at all costs. Tembi is one of the quasi-leaders of a resistance against that position, but even they are reluctant to ask the Deep to take sides in a war. To them, the Deep is a living magical creature that they are exploiting, and which also tends to be a bundle of nerves. Using it as a weapon feels like a step too far. That's how the situation lies at the start of this book when, after a successful bomb defusing, the Deep whisks Tembi away to watch an unknown weapon blow up a moon. A lot of this book consists of Tembi unraveling a couple of mysteries, starting with the apparent experimental bomb and then expanding to include the apparent drugging and disappearance of her former classmate. The low-grade war gets worse throughout, leaving Tembi torn between the justifications for Lancaster's neutrality and her strong sense of basic morality. The moments when Tembi gets angry enough or impatient enough to take action are the best parts, but a lot of this book is quite grim. Do not expect all to be resolved in a happy ending. There is some catharsis, but The Blackwing War is also clearly setup for a longer series. Tembi is a great character and the Deep is even better. I thoroughly enjoyed reading about both of them, and Tembi's relationship with the Deep is a delight. Usually I get frustrated by baffling incomprehensibility as a plot devices, but Spangler pulls it off as well as I've seen it done. But unfortunately, this book is firmly in the "gets worse before it will get better" part of the overall story arc, and the sequels have not yet appeared. The Blackwing War ends on a cliffhanger that portends huge changes for the characters and the setting, and if I had the next book to rush into, I wouldn't mind the grimness as much. As is, it was a somewhat depressing reading experience despite its charms, and despite a somewhat optimistic ending (that I doubt will truly resolve anything). I think the world-building elements were a touch predictable, and I wish Spangler wouldn't have her characters keep trying to justify Domino's creepy, abusive, and manipulative actions. But the characters are so much fun, and the idea of the Deep as a character is such a delight, that I am hooked on this series regardless. Recommended, although I will (hopefully) be able to recommend it more heartily once at least one sequel has been published. Content warnings: genocide, racism, violent death. Rating: 7 out of 10

The Long Now has an insightful article about air quality [1]. Every country needs food labelling laws like Mexico has [2]. Also we need to abolish the investor state tribunals, companies should just accept local laws and obey them or be treated in the same way as pirates on the high seas. Ian Jackson wrote a good post about conference policies regarding Covid19 [3]. We really need to do more about this, conservatives like to imagine that it s gone away but people are still getting sick and dying of it. John Goerzen wrote an informative article about air gaps and ways they can be part of a useful and usable security system [4]. This YouTube video has a good introduction to LLMs (Large Languge Models) for machine learning [5]. This eye tracker is interesting technology [6]. The video shows it being used for MS Flight Simulator but it can be used for other things. Unfortunately the price of about $550 Australian puts it out of range of a lot of free software work. I think this would be good for tracking the user FOR THEIR BENEFIT so that notifications won t be delivered when the user is concentrating. This ABC article about the risk of a past Covid19 infection exacerbating or accelerating Parkinson s or Alzheimer s is a worry [7]. Sam Hartman wrote an insightful blog post about AI safety, consent, and discussions of sex [8].

Dimitri John Ledkov: Ubuntu 23.10 significantly reduces the installed kernel footprint


Photo by Pixabay
Ubuntu systems typically have up to 3 kernels installed, before they are auto-removed by apt on classic installs. Historically the installation was optimized for metered download size only. However, kernel size growth and usage no longer warrant such optimizations. During the 23.10 Mantic Minatour cycle, I led a coordinated effort across multiple teams to implement lots of optimizations that together achieved unprecedented install footprint improvements.

Given a typical install of 3 generic kernel ABIs in the default configuration on a regular-sized VM (2 CPU cores 8GB of RAM) the following metrics are achieved in Ubuntu 23.10 versus Ubuntu 22.04 LTS:

  • 2x less disk space used (1,417MB vs 2,940MB, including initrd)

  • 3x less peak RAM usage for the initrd boot (68MB vs 204MB)

  • 0.5x increase in download size (949MB vs 600MB)

  • 2.5x faster initrd generation (4.5s vs 11.3s)

  • approximately the same total time (103s vs 98s, hardware dependent)


For minimal cloud images that do not install either linux-firmware or modules extra the numbers are:

  • 1.3x less disk space used (548MB vs 742MB)

  • 2.2x less peak RAM usage for initrd boot (27MB vs 62MB)

  • 0.4x increase in download size (207MB vs 146MB)


Hopefully, the compromise of download size, relative to the disk space & initrd savings is a win for the majority of platforms and use cases. For users on extremely expensive and metered connections, the likely best saving is to receive air-gapped updates or skip updates.

This was achieved by precompressing kernel modules & firmware files with the maximum level of Zstd compression at package build time; making actual .deb files uncompressed; assembling the initrd using split cpio archives - uncompressed for the pre-compressed files, whilst compressing only the userspace portions of the initrd; enabling in-kernel module decompression support with matching kmod; fixing bugs in all of the above, and landing all of these things in time for the feature freeze. Whilst leveraging the experience and some of the design choices implementations we have already been shipping on Ubuntu Core. Some of these changes are backported to Jammy, but only enough to support smooth upgrades to Mantic and later. Complete gains are only possible to experience on Mantic and later.

The discovered bugs in kernel module loading code likely affect systems that use LoadPin LSM with kernel space module uncompression as used on ChromeOS systems. Hopefully, Kees Cook or other ChromeOS developers pick up the kernel fixes from the stable trees. Or you know, just use Ubuntu kernels as they do get fixes and features like these first.

The team that designed and delivered these changes is large: Benjamin Drung, Andrea Righi, Juerg Haefliger, Julian Andres Klode, Steve Langasek, Michael Hudson-Doyle, Robert Kratky, Adrien Nader, Tim Gardner, Roxana Nicolescu - and myself Dimitri John Ledkov ensuring the most optimal solution is implemented, everything lands on time, and even implementing portions of the final solution.

Jonathan McDowell: Installing Debian on the BananaPi M2 Zero

My previously mentioned C.H.I.P. repurposing has been partly successful; I ve found a use for it (which I still need to write up), but unfortunately it s too useful and the fact it s still a bit flaky has become a problem. I spent a while trying to isolate exactly what the problem is (I m still seeing occasional hard hangs with no obvious debug output in the logs or on the serial console), then realised I should just buy one of the cheap ARM SBC boards currently available. The C.H.I.P. is based on an Allwinner R8, which is a single ARM v7 core (an A8). So it s fairly low power by today s standards and it seemed pretty much any board would probably do. I considered a Pi 2 Zero, but couldn t be bothered trying to find one in stock at a reasonable price (I ve had one on backorder from CPC since May 2022, and yes, I know other places have had them in stock since but I don t need one enough to chase and I m now mostly curious about whether it will ever ship). As the title of this post gives away, I settled on a Banana Pi BPI-M2 Zero, which is based on an Allwinner H3. That s a quad-core ARM v7 (an A7), so a bit more oompfh than the C.H.I.P. All in all it set me back 25, including a set of heatsinks that form a case around it. I started with the vendor provided Debian SD card image, which is based on Debian 9 (stretch) and so somewhat old. I was able to dist-upgrade my way through buster and bullseye, and end up on bookworm. I then discovered the bookworm 6.1 kernel worked just fine out of the box, and even included a suitable DTB. Which got me thinking about whether I could do a completely fresh Debian install with minimal tweaking. First thing, a boot loader. The Allwinner chips are nice in that they ll boot off SD, so I just needed a suitable u-boot image. Rather than go with the vendor image I had a look at mainline and discovered it had support! So let s build a clean image:

I had the advantage here of already having a host setup to cross build armhf binaries, but this was all done on a Debian bookworm host with packages from main. I ve put my build up here in case it s useful to someone - everything else below can be done on a normal x86_64 host. Next I needed a Debian installer. I went for the netboot variant - although I was writing it to SD rather than TFTP booting I wanted as much as possible to come over the network. 
noodles@buildhost:~/BPI$ wget https://deb.debian.org/debian/dists/bookworm/main/installer-armhf/20230607%2Bdeb12u1/images/netboot/netboot.tar.gz

Then I took a suitable microSD card and set it up with a 500M primary VFAT partition, leaving the rest for Linux proper. I could have got away with a smaller VFAT partition but I d initially thought I might need to put some more installation files on it.

At this point the installer runs and you can do a normal install. Well, except the wifi wasn t detected, I think because the netinst images don t include firmware. I spent a bit of time trying to figure out how to include it but ultimately ended up installing over a USB ethernet dongle, which Just Worked and was less faff. Installing firmware-brcm80211 once installation completed allowed the built-in wifi to work fine. After install you need to configure u-boot to boot without intervention. At the u-boot prompt (i.e. after hitting a key to stop autoboot): 
=> setenv bootargs "console=ttyS0,115200n8 root=LABEL=BPI-ROOT ro"
=> setenv bootcmd 'ext4load mmc 0:2 $ fdt_addr_r  /boot/sun8i-h2-plus-bananapi-m2-zero.dtb ; fdt addr $ fdt_addr_r  0x40000 ; ext4load mmc 0:2 $ kernel_addr_r  /boot/vmlinuz ; ext4load mmc 0:2 $ ramdisk_addr_r  /boot/initrd.img ; bootz $ kernel_addr_r  $ ramdisk_addr_r :$ filesize  $ fdt_addr_r '
=> saveenv
Saving Environment to FAT... OK
=> reset
This is assuming you have /boot on partition 2 on the SD - I left the first partition as VFAT (that s where the u-boot environment will be saved) and just used all of the rest as a single ext4 partition. I did have to do an e2label /dev/sdb2 BPI-ROOT to label / appropriately; otherwise I occasionally saw the SD card appear as mmc1 for Linux (I m guessing due to asynchronous boot order with the wifi). You should now find the device boots without intervention.

Aigars Mahinovs: Debconf 23 photos all

Two weeks have passed since Debconf 23 came to a close in Kochi, Kerala, India this year. In keeping with the more relaxed nature of Debconf in India, the rest of my photos from the event were to be published about two weeks from the end of the event. That will give me a bit more time to process them correctly and also give all of you a chance to see these pictures with fresh eyes and stir up new memories from the event. In the end we are looking at 653 photos and one video. Several different group photos, including a return of the pool group photo that was missing from the event since Mexico in 2006! This year was the first for a new camera (Canon R7) and I am quite happy with the results, even if I still need to learn a lot about this new beast. Also the gradual improvements of panorama stiching software (Hugin) ment that this year I did not need to manually correct any face-melt events on any of the group photos. So that is cool! DebConf 23 pool Group photo You can find all my photos on: Also, don't forget to explore the rest of the Git LFS share content - there are very many great photos by others this year as well!

Antoine Beaupr : OpenPGP key transition

This is a short announcement to say that I have changed my main OpenPGP key. A signed statement is available with the cryptographic details but, in short, the reason is that I stopped using my old YubiKey NEO that I have worn on my keyring since 2015. I now have a YubiKey 5 which supports ED25519 which features much shorter keys and faster decryption. It allowed me to move all my secret subkeys on the key (including encryption keys) while retaining reasonable performance. I have written extensive documentation on how to do that OpenPGP key rotation and also YubiKey OpenPGP operations.

Warning on storing encryption keys on a YubiKey People wishing to move their private encryption keys to such a security token should be very careful as there are special precautions to take for disaster recovery. I am toying with the idea of writing an article specifically about disaster recovery for secrets and backups, dealing specifically with cases of death or disabilities.

Autocrypt changes One nice change is the impact on Autocrypt headers, which are considerably shorter. Before, the header didn't even fit on a single line in an email, it overflowed to five lines:

Note that I have implemented my own kind of ridiculous Autocrypt support for the Notmuch Emacs email client I use, see this elisp code. To import keys, I pipe the message into this script which is basically just: 
sq autocrypt decode   gpg --import
... thanks to Sequoia best-of-class Autocrypt support.

Note on OpenPGP usage While some have claimed OpenPGP's death, I believe those are overstated. Maybe it's just me, but I still use OpenPGP for my password management, to authenticate users and messages, and it's the interface to my YubiKey for authenticating with SSH servers. I understand people feel that OpenPGP is possibly insecure, counter-intuitive and full of problems, but I think most of those problems should instead be attributed to its current flagship implementation, GnuPG. I have tried to work with GnuPG for years, and it keeps surprising me with evilness and oddities. I have high hopes that the Sequoia project can bring some sanity into this space, and I also hope that RFC4880bis can eventually get somewhere so we have a more solid specification with more robust crypto. It's kind of a shame that this has dragged on for so long, but Update: there's a separate draft called openpgp-crypto-refresh that might actually be adopted as the "OpenPGP RFC" soon! And it doesn't keep real work from happening in Sequoia and other implementations. Thunderbird rewrote their OpenPGP implementation with RNP (which was, granted, a bumpy road because it lost compatibility with GnuPG) and Sequoia now has a certificate store with trust management (but still no secret storage), preliminary OpenPGP card support and even a basic GnuPG compatibility layer. I'm also curious to try out the OpenPGP CA capabilities. So maybe it's just because I'm becoming an old fart that doesn't want to change tools, but so far I haven't seen a good incentive in switching away from OpenPGP, and haven't found a good set of tools that completely replace it. Maybe OpenSSH's keys and CA can eventually replace it, but I suspect they will end up rebuilding most of OpenPGP anyway, just more slowly. If they do, let's hope they avoid the mistakes our community has done in the past at least...

Shirish Agarwal: Birth Control, Consent, Rape & Violence.

Consent, Violence, Sexual Abuse This again would be somewhat of a mature post. So children, please refrain from reading. When I hear the above words, my first thought goes to Aamir Khan s Season 1 Episode 2 in Satyamev Jayate. This was the first time that the topic of child sexual abuse was bought in the forefront in the hall rather than a topic to be discussed in the corner. Unfortunately, that episode is still in Hindi and no English subtitles available even today shows a lack of sensitivity in Indian s part to still come to terms with Child abuse that happens in India. The numbers that they had shared at that time were shocking. More than 50 per cent children experience sexual abuse and mostly from friends or relatives. That means 1 in every 2 children. And this was in 2012. But the problem of child sexual abuse didn t start then, it started in the 1960 s, 70 s. In the 1960 s, 1970s we didn t have much of cinema and TV and whatever there was pretty limited. There were few B movie producers, but most of them came into their own in the 1980s. So what influenced Indians in those days were softcore magazines that either had a mature aunt or a teen and they would tease and sooner or later the man would sort of overpower them and fulfill his needs. Even mainstream Indian cinema used similar tropes. One of the most memorable songs of that era Wada Karo Nahi Chodoge Tum Meera Saath from Aa Gale Lag jaa. A bit of context for the song. This is where Shashi Kapoor sees, he tries to ask her to date him, she says no. He tries to put an act where he shows he can t skate or rather pretends. And kinda takes a promise from her that she will date him if he is able to skate. And viola, the next moment he is not just skating, but dancing and singing as well. And the whole he touches her and you can see that is uncomfortable and yet after a while he woos her. Now this is problematic today because we are seeing it from today s lens. It might also have problematic with the feminists of that time, but they probably would have been called overly sensitive or something like that. And this is what went in Universal cinema. But this is just tip of the surface. There were and are multiple poems and even art in those times that flirted and even sort of engaged with sexual molestation, rape both in poems as well as literature, both in Hindi and various regional literature. Similar to stuff that Keats and some other poets (problematic stuff) they wrote and where both men and women were in two minds, whether to take all the other good literature out or kinda make the difference between the art and artist. Now, while Aamir spoke about consent it wasn t in any official capacity or even a legal capacity. The interesting thing was that there was an Act that kinda put some safeguards but had been doing rounds for almost a decade. Because the extremists on both sides, Hindus and Muslims were not in favor of that Act, it was still doing rounds. Aamir s episode on 6th May 2012 and the discussions in mainstream media following that forced the Indian legislature to make POSCO as a law on 22nd May 2012. Almost 6 months to 2 weeks, Nirbhaya happened and changes to the law happened in another 6 months. Both voyeurism and stalking were made jailable offenses and consent became part of lingua franca in the Supreme Court. Couple of weeks back, I had shared in the Manipur case the part about fingering . In the same Act, another change that was done that insertion of any part including foreign objects in any of the openings would be classed as rape . So in that Manipur case, at least those 2-3 people who have been identified as clear perpetrators according to the law of land would be rapists and should have the highest punishment. Unfortunately, the system is rigged against women as Vrinda Grover had shared just couple of weeks back. How a 6 month fast track case (to be completed within 6 months) becomes a 10 year old case tells you the efficacy of the system. The reality is far more worse than is shared or known. Just a few months ago, GOI shared some data on Sexual Harassment in 2018-19. And this is after constant pressurizing by Activists that GOI doesn t like. In fact, in 2021, Unicef had shared data about how India was one of the five countries where child brides are still prevalent. India denied but didn t produce any alternative data. The firing of Mr. James over NHFS data sets doesn t give it any brownie points to the present Government. What has happened in the last few years is that the Government for reasons of its own had been scrubbing and censoring a lot of data. I won t go far, just 2 day old story which I had shared just couple of days back. Roughly a 25 year old RPF constable kills his superior and kills 3 Muslims after going to various coaches and then the Government uses the defence of temporary insanity.
Even the mental instability defence has twists and turns
Incidentally, Press Trust of India is s private organization and not the public broadcaster of the old. And incidentally, just a few days back, it came to light that they hadn t paid Income tax for last 2-3 years. Because of issues in reward money, the public came to know otherwise they wouldn t have known. Coming back to the topic itself, there was a video where you could hear and see the accused stating after killing the three Muslims that if you want to remain in India, then you have to vote for only Modi or Yogi, otherwise this will happen. That video was scrubbed both from Twitter as well as YouTube. All centralized platforms at the very least, whether it is Google (Youtube) or Twitter or Meta uses its own media ID. Meta s being most problematic but that probably being a discussion for another day. The same censorship tools are applied rigorously and lot of incidents are buried. Cases of girls being thrown in lakes just after lakes or low numbers of conviction in case of gang rapes are more often than not disappears.
The above article shared just a few days ago that how low the conviction rates of gang rapes are in Gujarat tells you the story. You might get the story today, but wait for a few weeks and you will find that the story has disappeared. What most people do not know or understand is that the web is increasingly a public repository of idea, imaginations and trust and authoritarian regimes like Government of India is increasingly using both official as well as unofficial methods to suppress the same. To see that in the last 9 odd years, GOI has made the highest number of takedown requests and been either number one or number two tells all. My question is where we do from here ??? If even the Minister and her Ministry can do only whataboutery rather than answer the questions, then how we are supposed to come up solutions. And even if a solution exists, without the state and Center agreeing and co-operating with civil society, any solution will be far off the desired result. I am sorry that I at least have no answers

C.J. Collier: Converting a windows install to a libvirt VM

Reduce the size of your c: partition to the smallest it can be and then turn off windows with the understanding that you will never boot this system on the iron ever again.
Boot into a netinst installer image (no GUI). hold alt and press left arrow a few times until you get to a prompt to press enter. Press enter. In this example /dev/sda is your windows disk which contains the c: partition
and /dev/disk/by-id/usb0 is the USB-3 attached SATA controller that you have your SSD attached to (please find an example attached). This SSD should be equal to or larger than the windows disk for best compatability. A photo of a USB-3 attached SATA controller To find the literal path names of your detected drives you can run fdisk -l. Pay attention to the names of the partitions and the sizes of the drives to help determine which is which. Once you have a shell in the netinst installer, you should maybe be able to run a command like the following. This will duplicate the disk located at if (in file) to the disk located at of (out file) while showing progress as the status. 
dd if=/dev/sda of=/dev/disk/by-id/usb0 status=progress
If you confirm that dd is available on the netinst image and the previous command runs successfully, test that your windows partition is visible in the new disk s partition table. The start block of the windows partition on each should match, as should the partition size. 
fdisk -l /dev/disk/by-id/usb0
fdisk -l /dev/sda
If the output from the first is the same as the output from the second, then you are probably safe to proceed. Once you confirm that you have made and tested a full copy of the blocks from your windows drive saved on your usb disk, nuke your windows partition table from orbit. 
dd if=/dev/zero of=/dev/sda bs=1M count=42
You can press alt-f1 to return to the Debian installer now. Follow the instructions to install Debian. Don t forget to remove all attached USB drives. Once you install Debian, press ctrl-alt-f3 to get a root shell. Add your user to the sudoers group: 
# adduser cjac sudoers
log out 
# exit
log in as your user and confirm that you have sudo 
$ sudo ls
Don t forget to read the spider man advice enter your password you ll need to install virt-manager. I think this should help: 
$ sudo apt-get install virt-manager libvirt-daemon-driver-qemu qemu-system-x86
insert the USB drive. You can now create a qcow2 file for your virtual machine. 
$ sudo qemu-img convert -O qcow2 \
/dev/disk/by-id/usb0 \
/var/lib/libvirt/images/windows.qcow2
I personally create a volume group called /dev/vg00 for the stuff I want to run raw and instead of converting to qcow2 like all of the other users do, I instead write it to a new logical volume. 
sudo lvcreate /dev/vg00 -n windows -L 42G # or however large your drive was
sudo dd if=/dev/disk/by-id/usb0 of=/dev/vg00/windows status=progress
Now that you ve got the qcow2 file created, press alt-left until you return to your GDM session. The apt-get install command above installed virt-manager, so log in to your system if you haven t already and open up gnome-terminal by pressing the windows key or moving your mouse/gesture to the top left of your screen. Type in gnome-terminal and either press enter or click/tap on the icon. I like to run this full screen so that I feel like I m in a space ship. If you like to feel like you re in a spaceship, too, press F11. You can start virt-manager from this shell or you can press the windows key and type in virt-manager and press enter. You ll want the shell to run commands such as virsh console windows or virsh list When virt-manager starts, right click on QEMU/KVM and select New.
In the New VM window, select Import existing disk image
When prompted for the path to the image, use the one we created with sudo qemu-img convert above.
Select the version of Windows you want.
Select memory and CPUs to allocate to the VM.
Tick the Customize configuration before install box
If you re prompted to enable the default network, do so now.
The default hardware layout should probably suffice. Get it as close to the underlying hardware as it is convenient to do. But Windows is pretty lenient these days about virtualizing licensed windows instances so long as they re not running in more than one place at a time. Good luck! Leave comments if you have questions.

Marco d'Itri: On having a track record in operating systems development

Now that Debian 12 has been released with proprietary firmwares on the official media, non-optional merged-/usr and systemd adopted by everybody, I want to take a moment to list, not without some pride, a few things that I was right about over the last 20 years: Accepting the obvious solution about firmwares took 18 years. My work on the merged-/usr transition started in 2014, and the first discussions about replacing sysvinit are from 2011. The general adoption of udev (and dynamic device names, and persistent network interface names...) took less time in comparison and no large-scale flame wars, since people could enable it at their own pace. But it required countless little debates in the Debian Bug Tracking System: I still remember the people insisting that they would never use this newfangled dynamic /dev/, or complaining about their beloved /dev/cdrom symbolic link and persistent network interface names. So follow me for more rants about inevitable technologies.

Shirish Agarwal: Odisha Train Crash and Coverup, Demonetization 2.0 & NHFS-6 Survey

Just a few days back we came to know about the horrific Train Crash that happened in Odisha (Orissa). There are some things that are known and somethings that can be inferred by observance. Sadly, it seems the incident is going to be covered up . Some of the facts that have not been contested in the public domain are that there were three lines. One loop line on which the Goods Train was standing and there was an up and a down line. So three lines were there. Apparently, the signalling system and the inter-locking system had issues as highlighted by an official about a month back. That letter, thankfully is in the public domain and I have downloaded it as well. It s a letter that goes to 4 pages. The RW is incensed that the letter got leaked and is in public domain. They are blaming everyone and espousing conspiracy theories rather than taking the minister to task. Incidentally, the Minister has three ministries that he currently holds. Ministry of Communication, Ministry of Electronics and Information Technology (MEIT), and Railways Ministry. Each Ministry in itself is important and has revenues of more than 6 lakh crore rupees. How he is able to do justice to all the three ministries is beyond me The other thing is funds both for safety and relaying of tracks has been either not sanctioned or unutilized. In fact, CAG and the Railway Brass had shared how derailments have increased and unfulfilled vacancies but they were given no importance In fact, not talking about safety in the recently held Chintan Shivir (brainstorming session) tells you how much the Govt. is serious about safety. In fact, most of the programme was on high speed rail which is a white elephant. I have shared a whitepaper done by RW in the U.S. that tells how high-speed rail doesn t make economic sense. And that is an economy that is 20 times + the Indian Economy. Even the Chinese are stopping with HSR as it doesn t make economic sense. Incidentally, Air Fares again went up 200% yesterday. Somebody shared in the region of 20k + for an Air ticket from their place to Bangalore Coming back to the story itself. the Goods Train was on the loopline. Some say it was a little bit on the outer, some say otherwise, but it is established that it was on the loopline. This is standard behavior on and around Railway Stations around the world. Whether it was in the Inner or Outer doesn t make much of a difference with what happened next. The first train that collided with the goods train was the 12864 (SMVB-HWH) Yashwantpur Howrah Express and got derailed on to the next track where from the opposite direction 12841 (Shalimar- Bangalore) Coramandel Express was coming. Now they have said that around 300 people have died and that seems to be part of the cover-up. Both the trains are long trains, having between 23 odd coaches each. Even if you have reserved tickets you have 80 odd people in a coach and usually in most of these trains, it is at least double of that. Lot of money goes to TC and then above (Corruption). The Railway fares have gone up enormously but that s a question for perhaps another time . So at the very least, we could be looking at more than 1000 people having died. The numbers are being under-reported so that nobody has to take responsibility. The Railways itself has told that it is unable to identify 80% of the people who have died. This means that 80% were unreserved ticket holders or a majority of them. There have been disturbing images as how bodies have been flung over on tractors and whatnot to be either buried or cremated without a thought. We are in peak summer season so bodies will start to rot within 24-48 hours No arrangements made to cool the bodies and take some information and identifying marks or whatever. The whole thing being done in a very callous manner, not giving dignity to even those who have died for no fault of their own. The dissent note also tells that a cover-up is also in the picture. Apparently, India doesn t have nor does it feel to have a need for something like the NTSB that the U.S. used when it hauled both the plane manufacturer (Boeing) and the FAA when the 737 Max went down due to improper data collection and sharing of data with pilots. And with no accountability being fixed to Minister or any of the senior staff, a small junior staff person may be fired. Perhaps the same official that actually told them about the signal failures almost 3 months back There were and are also some reports that some jugaadu /temporary fixes were applied to signalling and inter-locking just before this incident happened. I do not know nor confirm one way or the other if the above happened. I can however point out that if such a thing happened, then usually a traffic block is announced and all traffic on those lines are stopped. This has been the thing I know for decades. Traveling between Mumbai and Pune multiple times over the years am aware about traffic block. If some repair work was going on and it wasn t able to complete the work within the time-frame then that may well have contributed to the accident. There is also a bit muddying of the waters where it is being said that one of the trains was 4 hours late, which one is conflicting stories. On top of the whole thing, they have put the case to be investigated by CBI and hinting at sabotage. They also tried to paint a religious structure as mosque, later turned out to be a temple. The RW says done by Muslims as it was Friday not taking into account as shared before that most Railway maintenance works are usually done between Friday Monday. This is a practice followed not just in India but world over. There has been also move over a decade to remove wooden sleepers and have concrete sleepers. Unlike the wooden ones they do not expand and contract as much and their life is much more longer than the wooden ones. Funds had been marked (although lower than last few years) but not yet spent. As we know in case of any accident, it is when all the holes in cheese line up it happens. Fukushima is a great example of that, no sea wall even though Japan is no stranger to Tsunamis. External power at the same level as the plant. (10 meters above sea-level), no training for cascading failures scenarios which is what happened. The Days mini-series shares some but not all the faults that happened at Fukushima and the Govt. response to it. There is a difference though, the Japanese Prime Minister resigned on moral grounds. Here, nor the PM, nor the Minister would be resigning on moral grounds or otherwise :(. Zero accountability and that was partly a natural disaster, here it s man-made. In fact, both the Minister and the Prime Minister arrived with their entourages, did a PR blitzkrieg showing how concerned they are. Within 50 hours, the lines were cleared. The part-time Railway Minister shared that he knows the root cause and then few hours later has given the case to CBI. All are saying, wait for the inquiry report. To date, none of the accidents even in this Govt. has produced an investigation report. And even if it did, I am sure it will whitewash as it did in case of Adani as I had shared before in the previous blog post. Incidentally, it is reported that Adani paid off some of its debt, but when questioned as to where they got the money, complete silence on that part :(. As can be seen cover-up after cover-up FWIW, the Coramandel Express is known as the Migrant train so has a huge number of passengers, the other one which was collided with is known as sick train as huge number of cancer patients use it to travel to Chennai and come back

Demonetization 2.0 Few days back, India announced demonetization 2.0. Surprised, don t be. Apparently, INR 2k/- is being used for corruption and Mr. Modi is unhappy about it. He actually didn t like the INR 2k/- note but was told that it was needed, who told him we are unaware to date. At that time the RBI Governor was Mr. Urjit Patel who didn t say about INR 2k/- he had said that INR 1k/- note redesigned would come in the market. That has yet to happen. What has happened is that just like INR 500/- and INR 1k/- note is concerned, RBI will no longer honor the INR 2k/- note. Obviously, this has made our neighbors angry, namely Nepal, Sri Lanka, Bhutan etc. who do some trading with us. 2 Deccan herald columns share the limelight on it. Apparently, India wants to be the world s currency reserve but doesn t want to play by the rules for everyone else. It was pointed out that both the U.S. and Singapore had retired their currencies but they will honor that promise even today. The Singapore example being a bit closer (as it s in Asia) is perhaps a bit more relevant than the U.S. one. Singapore retired the SGD $10,000 as of 2014 but even in 2022, it remains as legal tender. They also retired the SGD $1,000 in 2020 but still remains legal tender.

So let s have a fictitious example to illustrate what is meant by what Singapore has done. Let s say I go to Singapore, rent a flat, and find a $1000 note in that house somewhere. Both practically and theoretically, I could go down to any of the banks, get the amount transferred to my wallet, bank account etc. and nobody will question. Because they have promised the same. Interestingly, the Singapore Dollar has been pretty resilient against the USD for quite a number of years vis-a-vis other Asian currencies. Most of the INR 2k/- notes were also found and exchanged in Gujarat in just a few days (The PM and HM s state.). I am sure you are looking into the mental gymnastics that the RW indulge in :(. What is sadder that most of the people who try to defend can t make sense one way or the other and start to name-call and get personal as they have nothing else

Disability questions dropped in NHFS-6 Just came to know today that in the upcoming National Family Health Survey-6 disability questions are being dropped. Why is this important. To put it simply, if you don t have numbers, you won t and can t make policies for them. India is one of the worst countries to live if you are disabled. The easiest way to share to draw attention is most Railway platforms are not at level with people. Just as Mick Lynch shares in the UK, the same is pretty much true for India too. Meanwhile in Europe, they do make an effort to be level so even disabled people have some dignity. If your public transport is sorted, then people would want much more and you will be obligated to provide for them as they are citizens. Here, we have had many reports of women being sexually molested when being transferred from platform to coach irrespective of their age or whatnot The main takeaway is if you do not have their voice, you won t make policies for them. They won t go away but you will make life hell for them. One thing to keep in mind that most people assume that most people are disabled from birth. This may or may not be true. For e.g. in the above triple Railways accidents, there are bound to be disabled people or newly disabled people who were healthy before the accident. The most common accident is road accidents, some involving pedestrians and vehicles or both, the easiest is Ministry of Road Transport data that says 4,00,000 people sustained injuries in 2021 alone in road mishaps. And this is in a country where even accidents are highly under-reported, for more than one reason. The biggest reason especially in 2 and 4 wheeler is the increased premium they would have to pay if in an accident, so they usually compromise with the other and pay off the Traffic Inspector. Sadly, I haven t read a new book, although there are a few books I m looking forward to have. People living in India and neighbors please be careful as more heat waves are expected. Till later.

Next.
