mls_export_netlbl_cat(9)

📦 version 7.3.1, in nixpkgs unstable

💅 mls_export_netlbl_cat(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: it's a kernel API manual page, section 9, and the star of the show is a little function called mls_export_netlbl_cat. she's lowkey iconic and honestly kind of a one-job girlie, but we stan. let's get into it ✨

🌸 NAME 🌸

mls_export_netlbl_cat — literally just exporting the MLS categories to NetLabel, that's the whole vibe 💫

🦋 SYNOPSIS 🦋

int mls_export_netlbl_cat (struct policydb *p , struct context *context
, struct netlbl_lsm_secattr *secattr );

no cap, that's the exact signature — copy it character for character or it will NOT compile, and we do not want that energy 😭

🎀 ARGUMENTS 🎀

  • p — the policy. yes, just "the policy", she's mysterious like that 👑
  • context — the security context, the main character of this whole operation 💖
  • secattr — the NetLabel security attributes, aka the destination where the good stuff goes 🧚

✨ DESCRIPTION ✨

so here's the tea: given the security context, this function copies the low MLS categories into the NetLabel MLS category field. that's it, that's the job. she copies, she slays, she leaves 🫶

and the return value? if it works you get zero back — success, we love to see it. if it doesn't, you get negative values, meaning failure, meaning something went sideways 😭

fr fr, anything negative = not the vibe. check it. always check it.

🌈 bye bestie 🌈
