Your expensive cloud observability stack is frozen, but do not worry, the Linux kernel has been hallucinating a zero-byte dashboard in RAM this whole time. 🫠 Read how to use it before your nodes crash completely. #DevOps #LinuxKernel

If I am the kernel of your life, then core.c is my promise to always choose you, fair.c is my vow to give you an equal and overflowing, share of my time, and rt.c is my guarantee that I will drop everything else the moment you call, my priority.

Linuxのデバイスは、大きくBlock DeviceとCharacter Deviceに分類できます。
・Block Device → ブロック単位でアクセス。HDD / SSDなど
・Character Device → バイトストリームとしてアクセス。端末 / シリアルポートなど

Linuxで read() / write() を実行したあと、内部では何が起きているのか？
ポイントは、ファイルI/O＝必ずストレージI/Oではないこと。
Page Cacheにデータがあれば、ストレージへアクセスせずに処理できる場合があります。
各レイヤーの役割は以下で説明しています👇

The final part of my Bad Epoll (CVE-2026-46242) 1-day analysis is up - from an 8-byte UAF all the way to root. I also jotted down a few takeaways worth remembering.

SLUB Allocator vs Buddy Allocator in Linux 🐧
They manage memory at different levels:
• Buddy Allocator → manages physical memory in pages
• SLUB Allocator → manages small kernel objects
• SLUB gets the pages it needs from the Buddy Allocator
#Linux #LinuxKernel #MemoryManagement
kmalloc() relies on two key Linux kernel memory allocators:
• SLUB manages and reuses small kernel objects.
• Buddy Allocator manages physical memory in page-sized blocks.
SLUB gets pages from the Buddy Allocator, divides them into smaller objects, and reuses freed objects for fast allocation.

☁️ Amazon Linux 2023’s “default” AMI now jumps from kernel 6.1 to 6.18. Convenient until a rolling SSM parameter turns production deployments into surprise compatibility tests. Pin it—or embrace chaos.

🐧 Linux 7.3 targets memory pressure where it hurts: fewer zRAM stalls and less KSM busywork scanning useless mappings. “The system is responsive” shouldn’t be an advanced feature.

🐉 Garuda’s Temeraire refresh swaps linux-zen for its own CachyOS-derived kernel and replaces SDDM with Plasma Login Manager. Fresh installs get a new stack—because “stable default” was apparently too mainstream.
