📦 version 7.3.1, in nixpkgs unstable

💅 aa_get_profile_rcu(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in AppArmor land, poking at profiles that other code might swap out from under you at literally any moment 👀 and you need to grab one safely and bump its refcount. That's the whole gig. It's giving "hold my spot, I'll be right back" energy 🎀

✨ NAME ✨

aa_get_profile_rcu — increment a refcount profile that can be replaced, no cap 🔥

Like, the profile is a moving target, and this function is how you snag it without things going sideways 💀

🌸 SYNOPSIS 🌸

struct aa_profile * aa_get_profile_rcu (struct aa_profile __rcu **p );

That's it. One parameter. One return. So clean, so iconic, honestly ✨

🦋 ARGUMENTS 🦋

  • p — pointer to profile that can be replaced — and like, NOT NULL, okay?? 🫶 This is not the function where you get to be cute and pass NULL. The docs said NOT NULL and they meant it. Respect the boundary 💅

👑 RETURN 👑

Returns a pointer to a refcounted profile — slay, now you own a reference and you're responsible for it 🎀

Otherwise it's NULL if there's no profile. That's the "nobody's home" result, and you should absolutely check for it 😭

🌈 SEE ALSO 🌈

Kernel file ./security/apparmor/include/policy.h — that's the mothership, go look 🧚

The whole refcount friend group fr fr — getters and putters living in harmony 💖

lowkey important: aa_get_profile_rcu and friends are the AppArmor refcount squad. Grab with a get, release with a put. If you get and never put, that's a leak bestie, and nobody wants that 😭🙈
