security_inode_getsecurity(9)

🎀 NAME 🎀

okay bestie, this is the security_inode_getsecurity(9) page from the Kernel API Manual, and it's all about getting the xattr security label of an inode. It's giving security-label detective energy. 💅✨

---

🌸 SYNOPSIS 🌸

int security_inode_getsecurity (struct mnt_idmap *idmap , struct inode *inode , const char *name , void **buffer , bool alloc );

---

🦋 ARGUMENTS 🦋

• idmap — the idmap of the mount.
• inode — the inode.
• name — the xattr name.
• buffer — the security label buffer.
• alloc — the allocation flag.

---

💖 DESCRIPTION 💖

okay so, this call retrieves a copy of the extended attribute representation of the security label associated with name for inode, and it sends that copy back via buffer. 🫶

Important lil note, bestie: name is the remainder of the attribute name after the security prefix has been removed. Like, the prefix is already gone when it gets here. 💅

And alloc is used to specify whether the call should return a value via buffer or just the value length. That's the whole vibe check. ✨

---

✨ RETURN ✨

Returns size of buffer on success. Slay. 👑
