[$] Preserving the mobility of ZONE_MOVABLE
Memory fragmentation has long been a problem for Linux systems, to the point that, for years, finding even two physically contiguous pages was an uncertain affair. That said, the situation has improved considerably in the last decade or so thanks to a number of changes implemented by the memory-management developers. One of those changes is the creation of […]

This is 2021: what’s coming in free/libre software (Libre Arts)
Libre Arts (formerly Libre Graphics World) has posted a comprehensive survey of what 2021 might hold for a wide range of free content-creation software. The topic of fullscreen color management implementation in Wayland is back, and it’s a kinda frustrating story. In a nutshell: people who are now working on this (Collabora developers) seem to have little ex […]

Corellium: How we ported Linux to the M1
The Corellium blog is carrying a description of how the Linux port to the Apple M1 processor was done. "Many components of the M1 are shared with Apple mobile SoCs, which gave us a good running start. But when writing Linux drivers, it became very apparent how non-standard Apple SoCs really are. Our virtual environment is extremely flexible in terms of […]

[$] Avoiding blocking file-name lookups
As a general rule, when one attempts to open a file with a system call like openat2(), the expectation is that the call will not return until the job is done. But there are times where the desire to open the file is conditional on being able to open it immediately, without blocking. Linux has never supported that mode well, but that may be about to change wi […]

[$] Installing Debian on modern hardware
It is an unfortunate fact of life that non-free firmware blobs are required to use some hardware, such as network devices (WiFi in particular), audio peripherals, and video cards. Beyond that, those blobs may even be required in order to install a Linux distribution, so an installation over the network may need to get non-free firmware directly from the inst […]

The Debian tech committee allows Kubernetes vendoring
Back in October, LWN looked at a conversation within the Debian project regarding whether it was permissible to ship Kubernetes bundled with some 200 dependencies. The Debian technical committee has finally come to a conclusion on this matter: this bundling is acceptable and the maintainer will not be required to make changes: Our consensus is that Kubernete […]

Another File Extension to Block in your MTA: .jnlp, (Fri, Jan 22nd) 22 Ιανουαρίου, 2021
When hunting, one thing that I like to learn is how attackers can be imaginative at deploying new techniques. I spotted some emails that had suspicious attachments based on the â€˜.jnlp&#x27 extension. I&#x27m pretty sure that many people don&#x27t know what&#x27s their purpose and, if you don&#x27t know them, you don&#x27t […]

I spotted a piece of Powershell code that deserved some investigations because it makes use of RunSpaces[1]. The file (SHA256:e1e19d637e6744fedb76a9008952e01ee6dabaecbc6ad2701dfac6aab149cecf) has a very low VT score: only 1/59![2].
