✨ tomoyo_realpath_from_path(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one lives in the TOMOYO security module and honestly it's giving path resolver but make it security-flavoured 🎀

---

🌸 NAME 🌸

tomoyo_realpath_from_path — returns realpath(3) of the given pathname, but ignores chroot'ed root 👑

lowkey important: the chroot part means it does not get fooled by a chroot jail, iykyk. Not me adding meaning — that's literally what it says 🫶

---

🦋 SYNOPSIS 🦋

char * tomoyo_realpath_from_path (const struct path *path );

one function, one pointer in, one char * out. slay ✨

---

🎀 ARGUMENTS 🎀

• path — pointer to "struct path" 🧚 that's it, that's the whole input, she's simple like that

---

💖 DESCRIPTION 💖

Returns the realpath of the given path on success, NULL otherwise 🔥

If the dentry is a directory, a trailing '/' is appended. periodt 📁

Characters out of the 0x20 < c < 0x7F range get converted to a style octal string. Characters that are \ get converted to a \ string. (yes bestie, the escaping is real, it's giving escape room but for filenames 😭)

💀 technically important: these functions use kzalloc, so the caller must call kfree if these functions didn't return NULL. Not me reminding you to free your memory — memory leaks are NOT the vibe 🙈

⭐ the sign-off ⭐

so this page comes from the source path ./security/tomoyo 🍓 and the date on it is October 2026 🗓️ and yes the version/date footer thing is here in spirit — the manual name up top is tomoyo_realpath_from_path(9) and that's her full government name 💜

go forth and resolve those paths, bestie 💅✨🦋
