ipe_bprm_creds_for_exec(9)

💅 NAME 💅

okay so bestie, this page is ipe_bprm_creds_for_exec(9) from the Kernel API Manual — and it's literally the ipe security hook function for bprm creds check. iconic behavior, no cap ✨

---

✨ SYNOPSIS ✨

int ipe_bprm_creds_for_exec (struct linux_binprm *bprm );

---

🎀 ARGUMENTS 🎀

• bprm — hands over a pointer to a linux_binprm structure, and that's what sources the file being evaluated. very "here's the file, do ur thing" energy 🫶

---

🦋 DESCRIPTION 🦋

so this LSM hook gets called when userspace signals the kernel to check a file for execution through the execveat syscall with the AT_EXECVE_CHECK flag. yes bestie, that whole little handshake 😌

the hook triggers IPE policy evaluation on the script file and returns the policy decision to userspace. the userspace program receives the return code and can decide whether to proceed with script execution. main character decision-making, honestly 👑

---

🌈 RETURN 🌈

• 0 — Success 💖
• -EACCES — Did not pass IPE policy 🙅‍♀️
