16 January 2025 - AT_EXECVE_CHECK

In anticipation of the Linux 6.14 merge window opening next week if Linux 6.13 releases as expected this coming Sunday, Google engineer Kees Cook has already sent out pull requests to Linus Torvalds of new feature code he's been aligning for the v6.14 cycle. One of the interesting pulls is the introduction of the AT_EXECVE_CHECK flag to the execveat call.

Linux To Allow Adjusting pid_max Per PID Namespace - Helping Old Software
19 January 2025 - pid_max per namespace

The pid_max tunable for the maximum number of process IDs allowed simultaneously was increased by default back in 2019 with systemd. But that increase breaks a long held assumption by some user-space software that pid_max or the process ID would not be greater than 65,535. To now better workaround such outdated user-space software, a set of patches for the Linux 6.14 kernel will allow adjusting the pid_max limit on a per PID namespace basis to help cope with such software hitting such artificial limits and without having to lower the overall system limit.

More Rust Code Is Coming For Linux 6.14 Along With Hitting Another "Major Milestone"
20 January 2025 - Linux 6.14 Rust

For the Linux 6.13 cycle the Rust code was hitting a "tipping point" with more Rust kernel drivers expected soon. For Linux 6.14 there is indeed a lot more Rust code being primed for this next kernel version.

分析了一下国际版、印度版、欧洲版和天（zhong）朝（guo）版当前最新版本的firmware，发现只有天朝版更新了adsp2。

因此，对于中国用户，如果你想安装AOSP roms，为避免遇到充电问题，请确保你的天朝版firmware不要新于OS1.0.9.0.UMRCNXM，或者改用国际版firmware，或者在使用最新的天朝版firmware的同时使用最新版本的Melt Kernel（笑）。

然后是自己的预感：等marble的官方版HyperOS 2发布以后，其他地区的firmware估计也会和天朝版一样更新adsp2 firmware。

Linus Torvalds Adapts Linux User Address Masking To Use CMOV
21 January 2025 - CMOV User Address Masking

In addition to merging a number of the pull requests yesterday for the start of the Linux 6.14 cycle, Linux creator Linus Torvalds did merge some of his own new code as well. While his time these days working on new kernel code itself is more limited with managing the ever-growing upstream kernel community, he has managed some notable items in recent times like addressing ARM64 kernel annoyances and some performance optimizations.

某些app会因为检测到KernelSU利用了kprobes而认为设备环境异常。因此为了避免被检测，应按照KernelSU的官方文档手动hook，就像在传统的内核上做的一样。

此提交使得我们能够在保持启用CONFIG_KPROBES的同时手动hook。

注：
内核拥有kprobes支持并不意味着环境异常，因为GKI默认就有kprobes支持，给GKI禁用kprobes反而会使得设备无法启动。
