Linux's Lockdown LSM Back To Being Maintained For Restricted Computing
31 July 2025 - Linux Lockdown

Upstreamed to the Linux kernel back in 2019 was the Lockdown security module for opt-in hardware/kernel security restrictions. It was a difficult and contentious process getting to the Linux kernel but then was left without any formal maintainer shortly after being mainlined. Now for helping to renew this Linux security module, two developers have stepped up to takeover maintainership of Lockdown.

Intel QuickAssist Hit By Second Demotion In Linux 6.17 Due To Lack Of Kernel Benefit
3 August 2025 - Intel QuickAssist

A few days ago the Intel QuickAssist "QAT" accelerators were demoted by FSCRYPT in the Linux 6.17 development code due to being slow and bug prone with AVX-512 showing to be much faster than leveraging the QAT accelerators in this file encryption framework. With the Linux 6.17 crypto subsystem is a second separate demotion to Intel's QAT support for kernel use.

Linux 6.17 Making Kdump Crash Kernel More Reliable, Less Wasted Memory
4 August 2025 - Linux 6.17 Kdump

In addition to the many MM changes merged this weekend for Linux 6.17, Andrew Morton on Sunday also sent out his "non-MM" pull request for this new kernel. Notable there is improving the Kdump code to allow for crash kernel reservation made from the contiguous memory allocator to help yield less wasted RAM and greater reliability.

我经常把Telegram的收藏夹当成安全、高效、可同步的便签功能使用，但使用Telegram这么多年我曾经遇到过一次收藏夹消息随机丢失的问题，并且只发生在Android客户端上。当时的解决方法有点笨：在PC客户端上把没丢失的消息转发给其他用户，再转发回来。
结果在昨天收藏夹消息随机丢失的问题又发生了一次，这次我随便摸索了一下，找到了解决方法：
在系统设置中查看Telegram的应用信息，点击“清除数据”，然后点击“管理空间”，在新界面点开右上角的菜单，然后点击“清除本地数据库”。

Linus Torvalds Rejects RISC-V Changes For Linux 6.17: "Garbage"
9 August 2025 - Linux 6.17 + RISC-V

Linus Torvalds has used his authority to reject the RISC-V architecture changes for the Linux 6.17 kernel. The RISC-V updates won't land this cycle and will need to try again for v6.18 later in the year. Linus refers to at least some of the proposed RISC-V code as garbage along with being submitted rather late during the merge window.

Reboot -> Redmi logo appears -> Black screen and automatic reboot before the boot animation appears -> Boots normally.
