💅 netlbl_domhsh_add_default — kernel API manual, section 9

okay so bestie, welcome to netlbl_domhsh_add_default(9) 💖 this one lives in the Kernel API Manual and it's basically the function that slides the default entry into the domain hash table. no cap, it's a whole moment.

✨ SYNOPSIS ✨

int netlbl_domhsh_add_default (struct netlbl_dom_map *entry , struct
       netlbl_audit *audit_info );

like, it takes two things and returns an int. that's it, that's the vibe 🎀

🫶 ARGUMENTS 🫶

  • entry — the entry to add 👑 this is the actual thing you're putting in there.
  • audit_info — the NetLabel audit information 🌸 yes, the audit receipts are part of the package, we love accountability.

🌈 DESCRIPTION 🌈

So what it does: it adds a brand-new default entry to the domain hash table, and it also handles any updates that need to happen to the lower level protocol handler — i.e. CIPSO 🦋 (that's literally how the original says it, "i.e. CIPSO", so we're keeping it exactly like that).

Return behaviour, listen up:

  • returns zero on success ✅ slay
  • returns negative on failure 💀 not slay
fr fr, check that return value. zero = good, negative = something went sideways. don't just ignore it and hope for the best 🙈
