[$] Collaboration for battling security incidents

Par : jake
25 mars 2026 à 17:07
The keynote for Sun Security Con 2026 (SunSecCon) was given by Farzan Karimi on how incident handling can go awry because of a lack of collaboration between the "good guys"—which stands in contrast to how attackers collaboratively operate. He provided some "war stories" where security incident handling had benefited from collaboration and others where it was hampered by its lack. SunSecCon was held in conjunction with SCALE 23x in Pasadena in early March.

Setting up a Tor Relay at National Taiwan Normal University (Tor Blog)

Par : jzb
25 mars 2026 à 15:10

The Tor Blog has an interesting article about the non-technical side of setting up a Tor Relay. It documents how a computer science student at National Taiwan Normal University worked with the university system to set up a relay and provides a template for future attempts:

In Taiwan, anonymous networks do not lack technical documentation or ideological support. The real scarcity is experience from actually working through the real institutional system once. Especially in an environment where academic networks are highly centralized and outbound connectivity is tightly controlled, distributed anonymous infrastructure like Tor Relays is inherently difficult to sustain.

This implementation at National Taiwan Normal University was not meant to provide a final answer for anonymous networks. It was a concrete attempt made within real-world institutions. It may not immediately improve the performance or security of anonymous networks, and it was not intended to become a directly reproducible standard process. What it did achieve was leaving behind a clearly visible path of practice—one that can be understood, referenced, and built upon.

LibreQoS v2.0 released

Par : jzb
25 mars 2026 à 14:46

Version 2.0 of the LibreQoS traffic-management and network operations platform has been released.

This release makes LibreQoS easier to operate, easier to understand, and much more useful for day-to-day network work. Now users can see more of what is happening across the network, troubleshoot subscriber issues with better tools, and work from a much stronger local WebUI.

This release includes many capabilities that reflect ideas and direction long championed by our late colleague, Dave Täht.

Dave's work helped shape the understanding of bufferbloat and the importance of latency under load across the networking community. His influence continues to guide both LibreQoS and the broader effort to improve Internet quality.

The project has also announced the release of the LibreQoS Bufferbloat Test v2, also dedicated to Täht. It runs in a user's browser to look at "latency under load, jitter, loss, and what those things mean for the kinds of traffic people actually care about: browsing, streaming, video calls, audio calls, backups, and gaming".

[$] More efficient removal of pages from the direct map

Par : corbet
25 mars 2026 à 14:32
The kernel's direct map provides code running in kernel mode with direct access to all physical memory installed in the system — on 64-bit systems, at least. It obviously makes life easier for kernel developers, but the direct map also brings some problems of its own, most of which are security-related. Interest in removing at least some pages from the direct map has been simmering for years; a couple of patch sets under discussion show some use cases for memory that has been removed from the direct map, and how such memory might be efficiently managed.

[$] A PHP license change is imminent

Par : jzb
24 mars 2026 à 16:00

PHP's licensing has been a source of confusion for some time. The project is, currently, using two licenses that cover different parts of the code base: PHP v3.01 for the bulk of the code and Zend v2.0 for code in the Zend directory. Much has changed since the project settled on those licenses in 2006, and the need for custom licensing seems to have passed. An effort to simplify PHP's licensing, led by Ben Ramsey, is underway; if successful, the existing licenses will be deprecated and replaced by the BSD three-clause license. The PHP community is now voting on the license update RFC through April 4, 2026.

LiteLLM on PyPI is compromised

Par : corbet
24 mars 2026 à 13:48
This issue report describes a credential-stealing attack buried within LiteLLM 1.82.8 in the PyPI repository. It collects and exfiltrates a wide variety of information, including SSH keys, credentials for a number of cloud services, crypto wallets, and so on. Anybody who has installed this package has likely been compromised and needs to respond accordingly.

Update: see this futuresearch article for some more information. "The release contains a malicious .pth file (litellm_init.pth) that executes automatically on every Python process startup when litellm is installed in the environment."

Down: Debunking zswap and zram myths

Par : corbet
24 mars 2026 à 13:34
Chris Down has posted a detailed look at how the kernel's zswap and zram subsystems work — and how they differ.

Most people think of zswap and zram simply as two different flavours of the same thing: compressed swap. At a surface level, that's correct – both compress pages that would otherwise end up on disk – but they make fundamentally different bets about how the kernel should handle memory pressure, and picking the wrong one for your situation can actively make things worse than having no swap at all

Krita 5.3.0 and 6.0.0 released

Par : jzb
24 mars 2026 à 13:31

The Krita project has announced the release of Krita 5.3.0 and 6.0.0:

Krita 5.3/6.0 is the result of many years of work by the Krita developers. Some features have been rewritten from the ground up, others make their first appearance.

Enjoy the completely new text feature: on canvas editing, full opentype support, text flowing into shapes. It is now easier than ever to create vector-based panels for comic pages. Tools got extended: for instance, the fill tool now can close gaps. The liquify mode of the transform tool is much faster. There are new filters: a propagate colors filter and a reset transparent filter. Support for HDR painting has been improved. The recorder docker can now work in real time. There is improved support for file formats, like support for text objects in PSD files. And much, much, much more!

According to the announcement, the versions are almost functionally identical. However, the 6.0.0 release is the first based on Qt 6; it has more Wayland functionality but is considered experimental. It cautions that users should stick to 5.3.0 for real work. See the release notes for a full list of changes.

[$] Tracking when BPF programs may sleep

Par : daroc
23 mars 2026 à 16:00

BPF programs can run in both sleepable and non-sleepable (atomic) contexts. Currently, sleepable BPF programs are not allowed to enter an atomic context. Puranjay Mohan has a new patch set that changes that. The patch set would let BPF programs called in sleepable contexts temporarily acquire locks that cause the programs to transition to an atomic context. BPF maintainer Alexei Starovoitov objected to parts of the implementation, however, so acceptance of the patch depends on whether Mohan is willing and able to straighten it out.

Agama 19 released

Par : jzb
20 mars 2026 à 18:41

Version 19 of the Agama installer for openSUSE and SUSE has been released. This release includes major changes in Agama's architectural design, organization of the web interface, and more.

We always wanted Agama to follow the schema [...] in which the core of the installer could be controlled through a consistent and simple programming interface (an API, in developers jargon). In that schema, the web-based user interface, the command-line tools and the unattended installation are built on top of that generic API.

But previous versions of Agama were full of quirks that didn't allow us to define an API that would match our quality standards as a solid foundation to build a simple but comprehensive installer. Agama 19 represents a quite significant architectural overhaul, needed to leave all those quirks behind and to define mechanisms that can be the cornerstone for any future development.

LWN last looked at Agama in September 2025.

[$] A truce in the Manjaro governance struggle

Par : jzb
20 mars 2026 à 18:06

Members of the Manjaro Linux distribution's community have published a "Manjaro 2.0 Manifesto" that contains a list of complaints and a demand to restructure the project to provide a clear separation between the community and Manjaro as a company. The manifesto asserts that the project's leadership is not acting in the best interests of the community, which has caused developers to leave and innovation to stagnate. It also demands a handover of the Manjaro trademark and other assets to a to-be-formed nonprofit association. The responses on the Manjaro forum showed widespread support for the manifesto; Philip Müller, project lead and CEO of the Manjaro company, largely stayed out of the discussion. However, he surfaced on March 19 to say he was "open to serious discussions", but only after a nonprofit had actually been set up.

Google details new 24-hour process to sideload unverified Android apps (Ars Technica)

Par : corbet
19 mars 2026 à 19:21
Ars Technica describes the ritual that will be required before a future Android device will deign to install apps from somewhere other than the Play Store. It is not for the impatient.

Here are the steps:
  • Enable developer options by tapping the software build number in About Phone seven times
  • In Settings > System, open Developer Options and scroll down to "Allow Unverified Packages."
  • Flip the toggle and tap to confirm you are not being coerced
  • Enter device unlock code
  • Restart your device
  • Wait 24 hours
  • Return to the unverified packages menu at the end of the security delay
  • Scroll past additional warnings and select either "Allow temporarily" (seven days) or "Allow indefinitely."
  • Check the box confirming you understand the risks.
  • You can now install unverified packages on the device by tapping the "Install anyway" option in the package manager.
