security_xf...lloc_acquire(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

security_xfrm_state_alloc_acquire — bestie, it allocates a xfrm state LSM blob 💖

okay so this page lives in the Kernel API Manual and its official abbreviated title is security_xf...lloc_acquire(9) (yes the truncation is serving cunty abbreviations, we don't question it) 🎀

🫶 SYNOPSIS 🫶

int security_xfrm_state_alloc_acquire (struct xfrm_state *x , struct xfrm_sec_ctx *polsec , u32 secid );

🎀 ARGUMENTS 🎀

  • x — the xfrm state that's being added to the SAD, she's the main character here 👑
  • polsec — the associated policy's security context, like her little entourage ✨
  • secid — the secid from the flow, okayyy we see you 🌸

🌈 DESCRIPTION 🌈

So the whole gig is: allocate a security structure into the x->security field. That's it, that's the task, and she ate 💅

Fun little detail you need to know though — that security field is initialized to NULL when the xfrm_state is allocated. So before this call it's just an empty little void, and we're the ones filling it in 🫶

And then, set the context to correspond to secid. No cap, that's literally the whole job 🔥

💖 RETURN 💖

Returns 0 if the operation was successful. That's the good ending, we love a zero, periodt ✨

🦋 SEE ALSO 🦋

Kernel file ./security/security.c — and honestly? the whole extended friend group showed up to the group chat. Every single one of them 💀

okay that's the whole page bestie, you're officially educated 🧚💜 mwah 💋

this lil masterpiece came out of ./security, dated October 2026, and yes she's filed under security_xf...lloc_acquire(9) because even kernel docs deserve a cute nickname 🎀⭐
