ima_measure_raw_policy(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay so bestie, this is the ima_measure_raw_policy(9) page from the Kernel API Manual, and it’s giving “measure the raw policy write buffer.” ✨ No cap, that’s the whole vibe: it measures the raw policy buffer. 💅

✨ SYNOPSIS ✨

int ima_measure_raw_policy (const char *buf , size_t buf_len );

🎀 ARGUMENTS 🎀

  • buf — pointer to the buffer containing the raw policy data 🫶
  • buf_len — size of the buffer 🌸

💅 DESCRIPTION 💅

okay so picture this: the function measures the raw policy buffer sent to the IMA policy securityfs file. The buffer is written from userspace, and the measurement is performed before parsing it. That means this measurement includes any data written on the policy file, such as malformed policy rules and comments — yes, even the messy stuff, bestie. 😭

Return 0 on success, a negative value otherwise. Periodt. 💖
