📰 AI Helped Uncover A "50-80x Improvement" For Linux's IO_uring
Linux block maintainer and IO_uring lead developer Jens Axboe recently was debugging some slowdowns in the AHCI/SCSI code with IO_uring usage. When turning to Claude AI to help in sorting through the issue, patches were devised that can deliver up to a "literally yield a 50-80x improvement on the io_uring side for idle systems." The code is on its way to the Linux kernel...

#今天又看了啥#security#提权#Linux#GitHub
The Dirty Pipe Vulnerability CVE-2022-0847
a vulnerability in the Linux kernel since 5.8 which allows overwriting data in arbitrary read-only files. This leads to privilege escalation because unprivileged processes can inject code into root processes.
It is similar to CVE-2016-5195 “Dirty Cow” but is easier to exploit.
The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102.
又一个 Linux kernel 本地提权,可覆盖重写任意只读文件中的数据,从而可将普通权限的用户提升到特权 root
影响范围 >=5.8, <5.16.11, 5.15.25 and 5.10.102

This is Probably the Best Video Downloader App (And it is Free and Open Source) | itsFOSS
VidBee allows you to download videos from YouTube, Facebook, X, Instagram, etc. In fact, it supports over 1,800 websites.
It is built on top of popular command line tools like yt-dlp and #ffmpeg. For the interface, it uses the Electron framework. I understand that some people dislike Electron framework as it runs a web browser underneath, but the 'advantage' of this framework is that you get the same interface in all the operating systems. At least, it's an advantage for the developers as they don't have to build the interface separately for #Linux, #Windows and #macOS.
The source code for VidBee is available on its GitHub repository.

[$] The future for Tyr
Tyr 团队在 2025 年初时,为 Arm Mali 硬件开发 Rust GPU 驱动的工作进展甚微。但到年底,他们已在 Linux Plumbers Conference 上成功运行了开源 3D 赛车游戏 SuperTuxKart。该原型由 Arm、Collabora 和 Google 合作开发,在会议期间运行稳定,性能足以满足游戏需求。
这一进展恰逢其时:Dave Airlie 在维护者峰会上宣布,DRM 子系统将在大约一年后禁止新的 C 语言驱动程序,并要求使用 Rust。因此,团队现在需要为 2026 年制定路线图,以期将所有工作整合到上游内核中。
