aa_free_ns(9)

📦 version 7.3.1, in nixpkgs unstable

💅 aa_free_ns(9) — like, the Kernel API Manual, but make it cute

okay so bestie, gather round, because today we're learning about aa_free_ns(9) from the Kernel API Manual (section 9, the ~cool~ section). Basically: it frees a profile namespace. That's the whole vibe. Simple, iconic, done. ✨

🎀 NAME 🎀

aa_free_ns — literally just frees a profile namespace. that's it. that's the function. 💖

🌸 SYNOPSIS 🌸

void aa_free_ns (struct aa_ns *ns );

no cap, that's the whole signature. void in, void out, namespace freed. slay. 🫶

🦋 ARGUMENTS 🦋

  • ns — the namespace to free. and listen, this one's marked (MAYBE NULL), so don't come for me if it's NULL, it's literally allowed. 🙈

✨ DESCRIPTION ✨

okay so here's the part you actually need to remember, bestie, because it's giving prerequisites and we do not skip prerequisites. 👑

Requires: all references to the namespace must have been put. like, all of them. every single one. gone. put already.

and if the namespace was referenced by a profile confining a task? yeah, those references need to be put too. don't be out here freeing a namespace that still has refs holding on — that's not the move. 😭

lowkey this is a "clean up your room before you redecorate" situation. put the references first, then free. periodt. 💅

🔥 SEE ALSO 🔥

the kernel file in question lives at ./security/apparmor/policy_ns.c — and here's the whole friend group, all tagged (9) because they're all in the same section, iykyk:

ngl that's a whole squad. go read them, they're all connected. 🌈⭐

and that's the page!! cute little sign-off time: this one came from the ./security/apparmor directory, dated October 2026, and it's filed under aa_free_ns(9) — like the header and footer said all along. 🍓🧚💜

mwah, go put your references before you free anything 💖
