A first of its kind Linux CVE dropped and in kernel code rewritten in Rust. The Rust rewrite introduced a race condition in a multi-threaded doubly linked list implementation leading to memory corruption.

This is the first formal CVE located in the Linux Rust code, a bit of an auspicious milestone.

Hello, hachyderm.io! I'm Artur Manuel, better known as @amadaluzia across other platforms.

I've been on Mastodon in the past under @amadaluzia@bsd.cafe, and recently moved in because I was self-consious about my status as a *BSD user. If you aren't sure who I am from that tag alone, I have a webpage that describes who I am that can be found in the following URL.

https://amadaluzia.is-a.dev

You should expect long posts from me, as I generally like to write long posts for the sake of detail. If you want short form posts, wait for a while until I have a reason to make a short post, which can be pretty hard to find. Otherwise, you'll at least have something to read. :D

Aside from the basic Mastodon tags, I'll add my interests as well. I hope we can get along!

I booted one of the original Slackware ARM development machines this week.

It’s a StrongARM RiscPC, running a Slackware ARM system that was last booted in April 2008. There was a kernel mismatch between the public builds and the original development kernel, so it took some careful archaeology to get it running; but it did boot, and I was able to log in and explore.

Is it Linux? Is it Windows? It's Winboat (https://github.com/TibixDev/winboat) a real Windows 11 VM, running inside a Docker container. Accessing the individual applications via xRDP.

And it works surpsisingly well! 🙂

Both #Mobian and #PostmarketOS (#Alpine #Linux) repositories block updates over #Tor, but so does GrapheneOS. However, it is possible to have onionized repositories with #Debian on #Termux.

proot-distro with alpine can install (apk add) #rust and #cargo. Just add the required libraries and #Arti is built! PostmarketOS is built on Alpine and, interestingly, "apks" and "sdks" derive from Alpine, not from Google.
https://pkgs.alpinelinux.org/package/edge/main/x86/rust

I wonder if microG can be installed in PostmarketOS. The Tor Browser should install on mobile linux devices (whether #Posh or #Gnome, etc). Until then, you can modify the proxy settings in #Firefox to use Arti. Onionsites could also be accessed this way.

I have it running on #NetBSD, #FreeBSD, #OpenBSD, #Linux, #MacOS, #IllumOS, #iOS, and have a user on the legacy #Android OS. That's basically everything that matters.

Friends,
Is there a good kind of course/ guide/ how to for learning how to use the terminal (I'm currently running Fedora Linux) for dummies. No crypic abbreviations, no "run this string of code" and then no further explanation, no assuming I know anything but how to open the terminal. Something that starts with telling me what everything means that I see even when I first open the terminal. How to do the most basic things, before going into the more interesting things. One stept after the other.

Please tell me there is such a thing? I really want to learn.

I don't even know what that means!

Whenever I see a “rice my Arch #Linux w/hyprland” video, I’m like:

You think that’s badass? You should’ve tried getting X11 running on a Linux machine in the mid-90s. You needed your monitor & video card manuals & a calculator (seriously) so you could calculate “modelines” for your X11 config file.

If you got the math wrong you’d fry your monitor by driving it at too high a frequency (back then nearly all monitors were fixed-frequency).

Typing “startx” for the first time was *so* stressful.

Does anyone knows good way to find #gig opportunity for software dev? I'd like to avoid pitfalls of well known platforms. I can do:
- #Rust CLI/Dev tools, APIs
- #C code (#FreeRTOS, #Zephyr, #Linux including some #drivers or #v4l2)
- #Cpp C++ code
- #Bash or #Python scripts, tools
- #CI workflows (GitHub, GitLab)
- #Yocto layers
- #Debian packaging + #DKMS

Anyone has experience in getting hands on small projects?

Edit: I can #teach / #training Rust or C++.

Two things in this Google Trends graph.

First, search interest in #Ansible peaked in 2019 and has been in general decline since. It's down about 25% from peak volume. During the same period, search volume for #NixOS has increased about 25%.

Second, every year in December, Google searches for #Ansible in the US plummet.

#Linux #DevOps

Alt...

Screenshot of Google trends graph with searches for Ansible going steadily down and NixOS searches going steadily up. Still about twice as many searches for Ansible, but if trends continue, the lines may cross in the next five years with NixOS being more popular.

Almost an hour spent trying to figure out why Flatpak-installed apps looked different on openSUSE Tumbleweed and Void Linux, configured the same way.
I just could not make sense of it.
Then I realized one was running Xorg and the other Wayland.

Needless to say, that was the problem…

And instead, they got loaded up with #nixbook and we gave them away to members of this community, along with a live demo, class and some Q&A.

Liebe Nerds und Geeks,
für unseren Linuxadmin David sind wir dringend auf der Suche nach einer Stellenquerfinanzierung
David ist Tetra-Spastiker, nutzt einen E-Rolli und hat eine Lernbehinderung.
Er ist #Linux Nerd und hat bei uns eine ehrenamtlich Sendung, den „Barrierefrei-Funk“, wo er über Missstände und Entwicklungen in Sachen Barrierefreiheit berichtet. Überhaupt setzt er sich aktiv für seine Belange und die anderer Menschen mit #Behinderung ein.
Dazu gehört auch sein starker Wunsch, auf dem ersten Arbeitsmarkt einer sinnvollen Beschäftigung nachzugehen.
Deutschland wurde bereits 2 mal gerügt, weil Menschen mit Behinderungen in gesonderte Schulen, Wohnheime und Werkstätten gezwungen werden statt sie zu integrieren und mit zu denken. 95% der Menschen in Werkstätten bleiben dort für immer. Egal ob das zu ihren Interessen und Fähigkeiten passt.
Fast kein Radioaktives muss sich dank Davids Engagement und Überzeugungskraft noch mit #Windows rumschlagen;)

Wir haben versucht ihn weiterhin als Administrator zu beschäftigen, so dass er nicht mehr unterbezahlt und unterfordert in einer Behindertenwerkstatt arbeiten muss.
Das Amt für Integration zahlt bei Eingliederung in den ersten Arbeitsmarkt 75 % des Arbeitnehmerbruttos. Leider können wir als nicht-kommerzielles Radio die restlichen Gelder für seine Arbeit nicht aufbringen und benötigen jährlich knapp 8.000 € für seine Stelle.
Wir stehen aktuell vor einem immer größer werdenden Finanzierungsloch und David droht die Rückkehr in die Werkstatt für Menschen mit Behinderung.
Aber gerade diese Stelle und sein Engagement im Barrierefreifunk sind wichtige Bausteine im Kampf gegen ableistische Strukturen.

Wir haben mit Beginn von Davids Stelle eine Betterplace Kampagne gestartet, die zwar durch die kurze Finanzierungsübernahme durch die LFK pausiert war, aber jetzt umso aktueller ist und die nun an die richtigen Leute geraten muss:
https://www.betterplace.org/de/projects/147170-lohnkostenbeteiligung-und-inklusion-fuer-linuxnerd

Wir wären euch super dankbar, wenn ihr die Kampagne teilt, sie euren Bitcoinmillionärs Freund*innen zukommen lasst und selbst als Crowd an einer inklusiveren Gesellschaft mitwirkt indem ihr für Davids Stelle monatlich oder einmalig was dazu gebt.
Sobald sich eine institutionelle Lösung auftut, an der wir dran sind, lassen wir es euch natürlich wissen.
Solong 1000- Dank schomal, guten Jahresendspurt und guten Congress
wünscht euch Lisa von radio dreyeckland
für Rückfragen und mehr Material erreicht ihr mich unter:
jugendredaktion@rdl.de
@ccc@anonsys.net
@CCC@social.bau-ha.us @cccfr

Another crowd wisdom toot...

I'm looking for an affordable #art /#drawing tablet. It should be reliable and work with #krita under #linux and maybe #windows.

I have no idea what I should be looking for/at, so any and all help or #retoot appreciated.

Good.

Thanks all who engaged on this thread re: my problems w/ hibernate (suspend-to-disk) on my new @novacustom laptop V54.

I've confirmed this problem has nothing to do w/ #NovaCustom, but an #Anker #Thunderbolt hub that I bought. Details: https://novacustom.com/forum/d/619-resume-after-hibernation-initially-worked-but-now-fails-every-time/2

The only thing left is I'd love advice on how to report this bug upstream to #Linux. I've truly never understood how to make useful bug reports to Linux itself, as problems are often so hardware specific.

Da Syncthing seit einiger Zeit nicht mehr funktionieren möchte, suche ich jetzt nach Input. Local Send ist mir für das, was ich gerne hätte, ehrlich gesagt ein wenig zu mühsam.

Syncthing behauptet seit einigen Wochen, es sei nicht erreichbar und ich finde den Fehler nicht. Ja, ich habe es schon mit Neuinstallation versucht. Ergebnis blieb das Gleiche.

Was ich möchte: Dass bestimmte Ordner ihre Textdokumente synchronisieren, weil ich manchmal auch am Laptop an einem Schreibprojekt fortfahren können möchte, ohne dann später händisch einzeln die Dateien schubsen zu müssen. Der aktuelle Laptop ist zwar auch irgendwie "durch", aber das ist ein anderes Thema.

Hat irgendwer Vorschläge, womit ich meine Dateien möglichst unkompliziert synchronisieren kann? Ja, im gleichen System/WLAN reicht mir für daheim rum eigentlich, wobei ich inzwischen auch kein Problem damit hätte, einen seriösen Cloud-Anbieter ein paar EUR zu geben.

(Ich hab jetzt dann Spätdienst und werde einiges erst später lesen)

((Der 15 Jahre alte Laptop wird demnächst gegen ein jüngeres Modell getauscht, auf das auch Linux Mint soll, also werde ich weiterhin Dateien zum Synchronisieren habe.))

TIL, when a thread calls mmap(2) with a fd on #linux, another thread can race with it to change the fd with a dup2(2) to have another fd mapped to memory. I wonder what #kernel people think about this. Do you think it's a bug worth reporting? I'm also curious how #bsd behaves, I plan to check.

So, I'm now desperate, as this is the only big blocker for my @novacustom laptop to meet my computing requirements.
I realize hibernatation to an encrypted partition can be tricky, but the tricky part isn't the problem because (given the logs) clearly the hibernate image is found during startup. I don't get why it says:

“Hibernate inconsistent memory map detected!”
“PM: hibernation: Image mismatch: architecture specific data”
