Debian Python 3 patch review, by Stefano Rivera Last month, at DebConf, Stefano reviewed the current patch set of Debian s cPython packages with Matthias Klose, the primary maintainer until now. As a result of that review, Stefano re-reviewed the patchset, updating descriptions, etc. A few patches were able to be dropped, and a few others were forwarded upstream. One finds all sorts of skeletons doing reviews like this. One of the patches had been inactive (fortunately, because it was buggy) since the day it was applied, 13 years ago. One is a cleanup that probably only fixes a bug on HPUX, and is a result of copying code from xfree86 into Python 25 years ago. It was fixed in xfree86 a year later. Others support just Debian-specific functionality and probably never seemed worth forwarding. Or good cleanup that only really applies to Debian. A trivial new patch would allow Debian to multiarch co-install Python stable ABI dynamic extensions (like we can with regular dynamic extensions). Performance concerns are stalling it in review, at the moment.

DebConf 24 Organization, by Stefano Rivera Stefano helped organize DebConf 24, which concluded in early August. The event is run by a large entirely volunteer team. The work involved in making this happen is far too varied to describe here. While Freexian provides funding for 20% of collaborator time to spend on Debian-related work, it only covers a small fraction of contributions to time-intensive tasks like this. Since the end of the event, Stefano has been doing some work on the conference finances, and initiated the reimbursement process for travel bursaries.

Archive rebuilds on Debusine, by Stefano Rivera The recent setuptools 73 upload to Debian unstable removed the test subcommand, breaking many packages that were using python3 setup.py test in their Debian packaging. Stefano did a partial archive-rebuild using debusine.debian.net to find the regressions and file bugs. Debusine will be a powerful tool to do QA work like this for Debian in the future, but it doesn t have all the features needed to coordinate rebuild-testing, yet. They are planned to be fleshed out in the next year. In the meantime, Debusine has the building blocks to work through a queue of package building tasks and store the results, it just needs to be driven from outside the system. So, Stefano started working on a set of tools using the Debusine client API to perform archive rebuilds, found and tagged existing bugs, and filed many more.

OpenSSH GSS-API split, by Colin Watson Colin landed the first stage of the planned split of GSS-API authentication and key exchange support in Debian s OpenSSH packaging. In order to allow for smooth upgrades, the second stage will have to wait until after the Debian 13 (trixie) release; but once that s done, as upstream puts it, this substantially reduces the amount of pre-authentication attack surface exposed on your users sshd by default .

OpenSSL vs. cryptography, by Colin Watson Colin facilitated a discussion between Debian s OpenSSL team and the upstream maintainers of Python cryptography about a new incompatibility between Debian s OpenSSL packaging and cryptography s handling of OpenSSL s legacy provider, which was causing a number of build and test failures. While the issue remains open, the Debian OpenSSL maintainers have effectively reverted the change now, so it s no longer a pressing problem.

/usr-move, by Helmut Grohne There are less than 40 source packages left to move files to /usr, so what we re left with is the long tail of the transition. Rather than fix all of them, Helmut started a discussion on removing packages from unstable and filed a first batch. As libvirt is being restructured in experimental, we re handling the fallout in collaboration with its maintainer Andrea Bolognani. Since base-files validates the aliasing symlinks before upgrading, it was discovered that systemd has its own ideas with no solution as of yet. Helmut also proposed that dash checks for ineffective diversions of /bin/sh and that lintian warns about aliased files.

rebootstrap by Helmut Grohne Bootstrapping Debian for a new or existing CPU architecture still is a quite manual process. The rebootstrap project attempts to automate part of the early stage, but it still is very sensitive to changes in unstable. We had a number of fairly intrusive changes this year already. August included a little more fallout from the earlier gcc-for-host work where the C++ include search path would end up being wrong in the generated cross toolchain. A number of packages such as util-linux (twice), libxml2, libcap-ng or systemd had their stage profiles broken. e2fsprogs gained a cycle with libarchive-dev due to having gained support for creating an ext4 filesystem from a tar archive. The restructuring of glib2.0 remains an unsolved problem for now, but libxt and cdebconf should be buildable without glib2.0.

Salsa CI, by Santiago Ruano Rinc n Santiago completed the initial RISC-V support (!523) in the Salsa CI s pipeline. The main work started in July, but it was required to take into account some comments in the review (thanks to Ahmed!) and some final details in [!534]. riscv64 is the most recently supported port in Debian, which will be part of trixie. As its name suggests, the new build-riscv64 job makes it possible to test that a package successfully builds in the riscv64 architecture. The RISC-V runner (salsaci riscv64 runner 01) runs in a couple of machines generously provided by lab.rvperf.org. Debian Developers interested in running this job in their projects should enable the runner (salsaci riscv64 runner 01) in Settings / CI / Runners, and follow the instructions available at https://salsa.debian.org/salsa-ci-team/pipeline/#build-job-on-risc-v. Santiago also took part in discussions about how to optimize the build jobs and reviewed !537 to make the build-source job to only satisfy the Build-Depends and Build-Conflicts fields by Andrea Pappacoda. Thanks a lot to him!

Why ISPs need IPv6? Providing a public IPv4 address to each customer is quite costly when each IP address costs US$40 on the market. For fixed access, some consumer ISPs are still providing one IPv4 address per customer.² Other ISPs provide, by default, an IPv4 address shared among several customers. For mobile access, most ISPs distribute a shared IPv4 address. There are several methods to share an IPv4 address:³

NAT44

The customer device is given a private IPv4 address, which is translated to a public one by a service provider device. This device needs to maintain a state for each translation.

464XLAT and DS-Lite

The customer device translates the private IPv4 address to an IPv6 address or encapsulates IPv4 traffic in IPv6 packets. The provider device then translates the IPv6 address to a public IPv4 address. It still needs to maintain a state for the NAT64 translation.

Lightweight IPv4 over IPv6, MAP-E, and MAP-T

The customer device encapsulates IPv4 in IPv6 packets or performs a stateless NAT46 translation. The provider device uses a binding table or an algorithmic rule to map IPv6 tunnels to IPv4 addresses and ports. It does not need to maintain a state.

Solutions to share an IPv4 address across several customers. Some of them require the ISP to keep state, some don't.

All these solutions require a translation device in the ISP s network. This device represents a non-negligible cost in terms of money and reliability. As half of the top 1000 websites support IPv6 and the biggest players can deliver most of their traffic using IPv6,⁴ ISPs have a clear path to reduce the cost of translation devices: provide IPv6 by default to their customers.

Why content providers need IPv6? Content providers should expose their services over IPv6 primarily to avoid going through the ISP s translation devices. This doesn t help users who don t have IPv6 or users with a non-shared IPv4 address, but it provides a better service for all the others. Why would the service be better delivered over IPv6 than over IPv4 when a translation device is in the path? There are two main reasons for that:⁵

1. Translation devices introduce additional latency due to their geographical placement inside the network: it is easier and cheaper to only install these devices at a few points in the network instead of putting them close to the users.
2. Translation devices are an additional point of failure in the path between the user and the content. They can become overloaded or malfunction. Moreover, as they are not used for the five most visited websites, which serve their traffic over IPv6, the ISPs may not be incentivized to ensure they perform as well as the native IPv6 path.

Looking at Google statistics, half of the users reach Google over IPv6. Moreover, their latency is lower.⁶ In the US, all the nationwide mobile providers have IPv6 enabled. For France, we can refer to the annual ARCEP report: in 2022, 72% of fixed users and 60% of mobile users had IPv6 enabled, with projections of 94% and 88% for 2025. Starting from this projection, since all mobile users go through a network translation device, content providers can deliver a better service for 88% of them by exposing their services over IPv6. If we exclude Orange, which has 40% of the market share on consumer fixed access, enabling IPv6 should positively impact more than 55% of fixed access users.

---

In conclusion, content providers aiming for the best user experience should expose their services over IPv6. By avoiding translation devices, they can ensure fast and reliable content delivery. This is crucial for latency-sensitive applications, like live streaming, but also for websites in competitive markets, where even slight delays can lead to user disengagement.

---

1. A way to limit this complexity is to build IPv6 services and only provide IPv4 through reverse proxies at the edge.
2. In France, this includes non-profit ISPs, like FDN and Milkywan. Additionally, Orange, the previously state-owned telecom provider, supplies non-shared IPv4 addresses. Free also provides a dedicated IPv4 address for customers connected to the point-to-point FTTH access.
3. I use the term NAT instead of the more correct term NAPT. Feel free to do a mental substitution. If you are curious, check RFC 2663. For a survey of the IPv6 transition technologies enumerated here, have a look at RFC 9313.
4. For AS 12322, Google, Netflix, and Meta are delivering 85% of their traffic over IPv6. Also, more than half of our traffic is delivered over IPv6.
5. An additional reason is for fighting abuse: blacklisting an IPv4 address may impact unrelated users who share the same IPv4 as the culprits.
6. IPv6 may not be the sole reason the latency is lower: users with IPv6 generally have a better connection.

GTK file chooser image preview size should be configurable The file chooser that appears when uploading a file (e.g. an image to Google Fotos) learned to show a preview in issue 15500. The preview image size is hard coded to 256x512 in kPreviewWidth and kPreviewHeight in ui/gtk/select_file_dialog_linux_gtk.cc. Please make the size configurable. On high DPI screens the images are too small to be of much use.
