💅 netlbl_domhsh_remove_entry — the Kernel API Manual, bestie edition

okay so welcome to netlbl_domhsh_remove_entry(9), the kernel API manual page you didn't know you needed in your life. it's giving "one small function, huge responsibilities" and honestly? iconic. let's get into it 🫶

✨ NAME ✨

netlbl_domhsh_remove_entry — removes a given entry from the domain table. that's it, that's the whole vibe. bye bye entry 👋

🌸 SYNOPSIS 🌸

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

it returns an int, it takes two pointers, and yes the line break mid-signature is just how the manpage dresses itself. slay 💅

🎀 ARGUMENTS 🎀

  • entry — the entry to remove. literally the main character of this whole operation. it's the thing getting yeeted from the domain table.
  • audit_info — NetLabel audit information. the receipts, basically. it's the audit stuff that tags along for the ride so the grown-ups can keep track 📋

💖 DESCRIPTION 💖

so what does it actually do? bestie, it removes an entry from the domain hash table ✨ and — this is the part people forget — it handles any updates to the lower level protocol handler (i.e. CIPSO). yes, CIPSO. it's not just deleting; it's doing the follow-up admin too. multi-tasking queen behavior 👑

🚨 IMPORTANT CAVEAT, NO CAP: the caller is responsible for ensuring that the RCU read lock is held. like, that's on you, not on the function. do not come for this function if you didn't hold the lock. the function is not the problem. 🙈

and the return values? cute and simple:

  • returns zero on success 🎉
  • returns negative on failure 😭

periodt. no in-between, no gray area. it ate and left no crumbs.
