__module_text_address(9)

💅 __module_text_address(9) 💅

okay so this page is from the Kernel API Manual, and it's literally here to answer: “which module's code contains this address?” No cap. 🫶

✨ NAME ✨

__module_text_address — get the module whose code contains an address.

🌸 SYNOPSIS 🌸

struct module * __module_text_address (unsigned long addr );

🎀 ARGUMENTS 🎀

• addr — the address. Like, the address you're asking about, bestie. 💖

🦋 DESCRIPTION 🦋

Okay so real talk: you must call this within an RCU read section or with the module mutex held. Why? So that the module doesn't get freed during this. That's the safety condition, and it is not optional, periodt. 🚨
