security_task_movememory(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay so bestie, welcome to security_task_movememory(9) straight outta the Kernel API Manual 💅 (yes that's the manual name, we're literally in the kernel's own docs now, main character energy fr)

security_task_movememory — the tiny little permission check that answers the question "are we allowed to move this process's memory?" 🧠✨ No cap, that's the whole vibe.

🌸 SYNOPSIS 🌸

int security_task_movememory (struct task_struct *p );

that's it. one function, one arg, zero drama 🎀

🎀 ARGUMENTS 🎀

  • p — the task. that's the task_struct pointer, the whole entire argument list, she's lowkey minimal and I respect it 💖

🦋 DESCRIPTION 🦋

so here's the tea 🍓: before memory that's owned by process p gets moved, this hook gets called to check permission first. That's it. That's the job. It's a vibe check for memory relocation, and it takes its little job very seriously 🧚

Think of it as the bouncer at the door of memory-moving, except instead of a velvet rope it's an LSM hook and instead of a clipboard it's a permission check ✨

🔥 RETURN 🔥

Returns 0 if permission is granted. 🫶 Zero means yes, bestie — green light, go ahead, move that memory 👑

👑 SEE ALSO 👑

okay this is the part where I need you to sit down and hydrate 💀 because the SEE ALSO section on this one is iconic in the "there are a LOT of them" sense. They all live in the kernel file ./security/security.c — same house, same family reunion, no one's leaving early 🌈

bestie if you read that whole list you're genuinely built different 💀 iykyk

anyway that's the page!! 🎀 source is ./security and she's dated October 2026 — so take that up with the ./security directory if you've got notes, xoxo 💜🦋✨
