smk_curacc(9)

💅 smk_curacc(9) — like, the Kernel API Manual one, bestie

okay so real talk, this is smk_curacc from section 9 of the Kernel API Manual and it's literally the vibes-check function for Smack access. buckle up 🎀

---

✨ NAME ✨

smk_curacc — determine if current has a specific access to an object 🫶

(yes that's the whole name section, she said what she said)

---

🌸 SYNOPSIS 🌸

int smk_curacc (struct smack_known *obj_known , u32 mode , struct
smk_audit_info *a );

that's the signature, copy it exactly, no cap 💅

---

🦋 ARGUMENTS 🦋

• obj_known — a pointer to the object's Smack label entry. like, the label of the thing you're trying to touch ✨
• mode — the access requested, in "MAY" format 🔥
• a — common audit data 🎀

---

💖 DESCRIPTION 💖

so what she does is: this function checks the current subject label/object label pair in the access rule list, and returns 0 if the access is permitted, non zero otherwise. iconic behaviour honestly.

and the little bonus: it allows that current may have the capability to override the rules. main character energy, she can skip the line if she's got the cap 👑
