aa_ns_visible(9)

📦 version 7.3.1, in nixpkgs unstable

✨ aa_ns_visible ✨

okay so bestie, welcome to aa_ns_visible 🎀 — straight out of the Kernel API Manual, and honestly? she's a little icon. the whole gig is <cyan>aa_ns_visible</cyan> — as in, test if @view is visible from @curr 👀💅

🌸 SYNOPSIS 🌸

like, here's the whole signature, no cap:

bool aa_ns_visible (struct aa_ns *curr , struct aa_ns *view , bool subns
);

she returns a bool, she takes three args, she's lowkey doing the most for namespace visibility checks. periodt 💜

🦋 ARGUMENTS 🦋

  • curr — the namespace you're treating as the parent. and babes, she is NOT NULL — like, do not even try it 🙈
  • view — the namespace you're testing to see if it's visible from curr. also NOT NULL, same energy, no exceptions ✨
  • subns — a bool that says whether view of a subns is allowed. yes ma'am, that's the whole vibe check 🫶

💖 RETURN 💖

  • true if view is visible from curr — slay! 👑
  • otherwise false — she said nope 💀

fr fr, that's the entire return situation. no hidden lore.

🌈 SEE ALSO 🌈

the Kernel file ./security/apparmor/policy_ns.c is the main character here, and she brought her whole friend group 💅:

ngl bestie, all three pointers being NOT NULL is not a suggestion, it's a lifestyle. respect the contract or catch these crashes 😭🔥

and that's the whole page, mwah 💋 big sign-off energy: brought to you by ./security/apparmor, stamped October 2026, and yes she ate 🌟🎀🦋
