anon_inode_create_getfile(9)

💫 anon_inode_create_getfile(9) 💫

okay so bestie, welcome to the Kernel API Manual — this one is anon_inode_create_getfile, and it's lowkey iconic. sit down, grab a strawberry 🍓, let's get into it.

---

✨ NAME ✨

anon_inode_create_getfile — it's literally like anon_inode_getfile(), except instead of reusing the singleton anon inode, it creates a brand new !S_PRIVATE anon inode. and it calls the inode_init_security_anon() LSM hook. no cap, that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

struct file * anon_inode_create_getfile (const char *name , const struct
       file_operations *fops , void *priv , int flags , const struct inode
       *context_inode );

---

🦋 ARGUMENTS 🦋

• name [in] — the name of the "class" of the new file. it's giving label energy. 🏷️
• fops [in] — the file operations for the new file. the whole personality, fr fr.
• priv [in] — private data for the new file. heads up: this will literally become the file's private_data. 💅
• flags [in] — flags. yes. that's the description. flags. 🫶
• context_inode [in] — the logical relationship with the new inode, and it's optional. optional! we love a low-pressure king. 👑

---

💖 DESCRIPTION 💖

so it creates a new anonymous inode and file pair. a matched set. main character energy for both of them. ✨

you'd do this for two reasons, and only two, and here they are:

• so the inode can have its own security context, so that LSMs can enforce policy on the inode's creation. security girlies rise. 🔥
• if the caller needs a unique inode — for example, in order to customize the size returned by fstat. bespoke. artisanal. 🎀

quick heads up bestie: the LSM may use context_inode in inode_init_security_anon, but a reference to it is not held. so don't go assuming it's gonna stick around for you. 😭

it returns the newly created file* or an error pointer. slay either way. 💀
