🌍 Ambiente, Ecologia e Mobilità Sostenibile
Benvenutə nel Gruppo per la sostenibilità ambientale e la mobilità sostenibile su Diggita
Uno spazio per attivistə, cittadinə, ricercatorə e chiunque non voglia più stare a guardare mentre il pianeta brucia. Qui pensiamo con azione: discutiamo di ecotransizione, conservazione della biodiversità, ma anche di mobilità sostenibile — perché cambiare il modo in cui ci muoviamo è parte fondamentale della rivoluzione climatica. Consigli green su come vivere in spazi verdi giardinaggio: piante, fiori e orti urbani Consapevolezza ambientale: suggerimenti concreti per viaggiare con minor consumo, privilegiando mezzi eco-friendly, valorizzando la biodiversità e contribuendo a tutela del patrimonio naturale e culturale.

Computing to support life on Earth
Computing in the age of climate crisis is often wasteful and adds nothing useful to our real life communities. Here we try to find out how to change that.

I'm Nick, and I like to tinker with Linux stuff. I'll bumble through distro reviews, tutorials, and general helpful tidbits and impressions on Linux desktop environments, applications, and news. You might see a bit of Linux gaming here and there, and some more personal opinion pieces, but in the end, it's more or less all about Linux and FOSS !

Sourced from thirteen subreddits, Reddit's AI-generated answers began: Richard Stallman and Linus Torvalds do not actively cooperate; their relationship is often characterized by ideological differences rather than direct collaboration. While both are foundational figures in free and open-source software, their distinct philosophies and approaches have led to a separation in their work. … -

Port knocking is mostly a bad idea. But people keep wanting to do it, for some false sense of security. If you don't consider it a security control but a way to keep garbage out of your logs, it might be valid. In my case I'm using an old USG Pro 4 running OpenBSD as my firewall and I'd prefer to avoid writing stuff to the logs, as I'd prefer the flash not to wear out sooner than needed, definitely not thanks to background radiation on the internet.

OpenBSD's sppp_pap_input function used attacker-controlled length fields as the bcmp comparison length for credential validation. Sending zero-length name and password fields caused bcmp to return 0 unconditionally, bypassing PAP authentication entirely. The vulnerability was introduced in 1999 and survived for 27 years before being fixed.

https://freebsdfoundation.org/blog/freebsd-ai-assisted-vulnerability-discovery-project-launch/
… the key goal of reducing the number of exploitable vulnerabilities in the FreeBSD source code.
The 6-month project is being funded by a grant from the Alpha Omega project. The funds will be used to engage FreeBSD Security Team members under fixed-term contracts to find and patch vulnerabilities. The Security Team’s access to publicly available AI models and tokens will be provided free of charge. AI will be used for vulnerability discovery and analysis only, all patches will be manually created.

The purpose of this post is to summarise the various details regarding upcoming changes, improvements and new features in Linux 7.1.
See:
⇒ Linux 7.1 Lands ARM64 NEON-Accelerated CRC64-NVMe For ~6x Improvement:
Descr: Merged 13/04 were all the CRC code updates for the Linux 7.1 kernel. Most notable with that pull is an ARM64-optimized CRC64-NVMe implementation that can deliver multiple times faster performance...⇒ Linux 7.1 Revamps T10 PI Data Integrity Handling For Better Read Performance:
Descr: Merged 13/04 for the Linux 7.1 kernel is overhauling the T10 PI code for generating and verifying data integrity information. In turn the new code is cleaner while also allowing for better read storage performance...⇒ Linus Torvalds Rejects Performance Fix "Hack" & Kconfig "Terrible Things" For Linux 7.1:
Descr: While a lot of interesting new features and changes have been merged already for the Linux 7.1 merge window, two pull requests stand out so far for being rejected by Linus Torvalds and complete with his to-the-point commentary...⇒ LLM-Assisted Patches For Linux 7.1 May Have Negative Impact On 32-bit Systems:
Descr: Code now merged for the Linux 7.1 kernel may provide some negative performance implications for those still running modern Linux kernels on 32-bit hardware. A fundamental change can present cache line alignment and slab sizing implications for 32-bit Linux OS users but will provide for cleaner code with modern 64-bit computing...⇒ Linus Torvalds Merged The Code Beginning To Remove Intel 486 CPU Support In Linux 7.1:
Descr: As a follow-up to the news first-covered on Phoronix earlier this month about Linux 7.1 expected to begin removing i486 CPU support: it indeed happened. Linus Torvalds took the initial removal bits today without any fuss today for beginning the phase out of M486 / M486SX / ELAN kernel support...⇒ exFAT For Linux 7.1 Helps Reduce File Fragmentation, Fixes:
Descr: The exFAT file-system changes have landed for the in-development Linux 7.1 kernel...⇒ Linux 7.1 Gets Rid Of Some Unnecessary Memory Clobbers:
Descr: The x86/asm changes merged yesterday for the Linux 7.1 kernel with a few low-level improvements...⇒ AMD EDAC Driver In Linux 7.1 Adds Support For Zen 3 Rembrandt Hardware With ECC:
Descr: The Error Detection And Correction "EDAC" subsystem updates have been merged for Linux 7.1 that deal with reporting of ECC memory errors and the like from various hardware drivers...⇒ Linux 7.1 Adds New Child Auto-Reap & PIDFD Auto-Kill Flags For clone3():
Descr: The clone3() system call in Linux 7.1 is adding three new flags for greater control over the creation of child processes...
If someone has others sources of informations about this topic, please, do not hesitate to post-IT!
(06/15) ⇒ Linux Kernel 7.1 is a Feature Release That Could Be Useful For You Don't let the .1 fool you, this release has plenty to offer. https://itsfoss.com/news/linux-kernel-7-1-release/ ⇒ GNU Linux-libre 7.1-gnu Released With More Driver Deblobbing, Unhappy With i486 Removal Following yesterday's release of the upstream Linux 7.1 kernel release, GNU Linux-libre 7.1 is out with its new build for de-blobbing various drivers from loading non-free-software microcode/firmware and other sanitizing of the kernel code in the name of software freedom. https://www.phoronix.com/news/GNU-Linux-Libre-7.1 -

Code, using the button in the editor here:
I remade the post with
text-specific formatting. No better, still wrapped in Mastodon:

Essentially, two commands:
pkg upgrade -Fqypkg upgrade -qUy && shutdown -r +30 "restarting with an upgraded kernel"
– it was not necessary to repeat the first.

Generating apropos(1) database for /usr/share/openssl/man... ===== Message from FreeBSD-local-unbound-15.1: -- After upgrading local-unbound, the configuration file should be regenerated by running "service local_unbound setup" before restarting the service. root@clean:~ # freebsd-version -kru ; uname -KU 15.1-RELEASE 15.1-RC3-p1 15.1-RELEASE 1501000 1501000 root@clean:~ # shutdown -r +30 "restarting with an upgraded kernel"Please note
This is not an encouragement to perform upgrades before official announcements.
For the second command, I used the
--quietand--yesoptions only because in this case – a test machine in VirtualBox – I had confidence that installing packages would have no adverse effect. You should never combine those two options without knowing exactly what you're doing.It was a simple upgrade, not a minor or major upgrade.

It's a sensationalist article, which is not a bad thing in this case.
Less sensationally, but critical (9.8/10):
For the other three vulnerabilities, all moderate, that are mentioned in the article:
- Vulnerability in the PeopleSoft Enterprise PeopleTools... · CVE-2026-21934 · GitHub Advisory Database
- Vulnerability in the PeopleSoft Enterprise HCM Shared... · CVE-2026-22019 · GitHub Advisory Database
- Vulnerability in the PeopleSoft Enterprise FIN... · CVE-2026-34299 · GitHub Advisory Database
This week's breach is all over the news, I first found it at https://mastodon.opencloud.lu/@BrideOfLinux/116737809000928257 from @BrideOfLinux@mastodon.opencloud.lu

(06/10) ⇒ OpenBSD stories—Trojaned OpenSSH This is a story I had been considering writing for a long time, as many wrong or stupid things have been said or written at the time it happened. Being on a quite sensitive subject, I have however opted to redact a few things, especially the identity of two OpenBSD developers, as well as some IP addresses and other minor details which could help identify them. They will be referred to as dev1 and dev2 in this story. It does not matter who they are, and they really are trustworthy. http://miod.online.fr/software/openbsd/stories/trojan.html Very interesting!
