match_mnt_path_str(9)

💅 match_mnt_path_str — kernel API manual, bestie edition 🎀

Okay so like, welcome to the match_mnt_path_str(9) page, which lives in the Kernel API Manual and is genuinely just here to handle path matching for mount. That's it, that's the plot. Slay. ✨

🌸 NAME 🌸

match_mnt_path_str — handle path matching for mount 🗂️

---

🦋 SYNOPSIS 🦋

int match_mnt_path_str (struct aa_profile *profile , const struct path
*mntpath , char *buffer , const char *devname , const char *type ,
unsigned long flags , void *data , bool binary , const char *devinfo ,
struct apparmor_audit_data *ad );

One function, ten arguments, absolutely main character energy. Not me counting them like a girlboss. 🔥

---

✨ ARGUMENTS ✨

Bestie, there's a lot of them, but they all pull their weight:

• profile — the confining profile 👑 the one doing the confining, the icon, the moment.
• mntpath — for the mntpnt. And listen: it is NOT NULL. Like, do not pass NULL. I'm serious. 🚫
• buffer — buffer to be used to lookup mntpath 🧺 your little lookup workspace.
• devname — string for the devname / src_name. This one is chill: it MAY BE NULL OR ERRPTR 🫶 yes literally either.
• type — string for the dev type. MAYBE NULL — typo's in the original, we keep it, we love it 🙈
• flags — mount flags to match 🚩
• data — fs mount data. MAYBE NULL 🍓
• binary — whether data is binary. true/false vibes, no cap 💀
• devinfo — error str if IS_ERR(devname) 😭 i.e. the string that explains what went wrong with devname.
• ad — apparmor audit data structure 📋 the receipts.

---

⭐ RETURN ⭐

0 on success, else error. That's it. Zero = slay, anything else = the vibe check failed. 🌈

Ngl, "error" is doing a lot of heavy lifting here — the page says error and we're not out here inventing codes. 😌
