security_ker...dule_request(9)

💅 security_kernel_module_request(9) ✨

okay so this is a page from the Kernel API Manual and it's genuinely so straightforward bestie, like a little vibe check for module loading. the function name gets truncated in the header as security_ker...dule_request(9) because manpage headers have zero chill about long names, but the real one is security_kernel_module_request. let's get into it 🫶

---

🌸 NAME 🌸

security_kernel_module_request — checks if loading a module is allowed 💖

---

✨ SYNOPSIS ✨

int security_kernel_module_request (char *kmod_name );

that's it. that's the whole function. one arg, returns an int, main character energy 👑

---

🎀 ARGUMENTS 🎀

• kmod_name — the module's name 🏷️ like literally just the name of the module, that's the whole argument, slay

---

🦋 DESCRIPTION 🦋

okay so the way this works is: this hook covers the ability to trigger the kernel to automatically upcall to userspace, so that userspace loads a kernel module with the given name ✨

that's the whole description ngl, it's giving "short and iconic." no cap, the manpage really said "here's the one sentence, take it or leave it" 💀

---

🌈 RETURN 🌈

returns 0 if successful 💖 (yes, that's the only return value listed, and yes, it's giving minimalist queen 👑)

👑 SEE ALSO 👑

so the SEE ALSO section on this one is... a lot. like, a lot a lot. it's the entire LSM cinematic universe fr fr 😭 starting with the kernel file ./security/security.c and then just going absolutely feral:

like. bestie. that is every LSM hook. whoever generated this page said "link everything" and honestly? respect 💅

ok real talk — that list is long enough that your terminal is gonna scroll for a min, but every single one of those is a real reference from the original page, so no skipping, no cap 🔥

🧚 a lil sign-off 🧚

this gem comes from the source path ./security and it's dated October 2026 ✨ keep it cute, keep your modules checked, and remember: security_kernel_module_request(9) is literally just here to ask "is this allowed bestie?" before your kernel goes off and upcalls to userspace 💖🎀🦋
