💖 netlbl_mgmt_add_common(9) 💖

okay bestie, so this one's from the Kernel API Manual (yes, the kernel has a manual and yes it's kind of iconic) — it's netlbl_mgmt_add_common, and no cap it's the little helper that handles an ADD message. let's get into it 🫶

---

✨ NAME ✨

netlbl_mgmt_add_common — literally just "Handle an ADD message" 💅

---

🦋 SYNOPSIS 🦋

int netlbl_mgmt_add_common (struct genl_info *info , struct netlbl_audit
*audit_info );

like, it takes two things and gives you back an int, that's the whole vibe 🌸

---

🎀 ARGUMENTS 🎀

• info — the Generic NETLINK info block. that's the message payload situation right there ✨
• audit_info — the NetLabel audit information. receipts for the audit trail, iykyk 👑

---

💜 DESCRIPTION 💜

so this is a helper function for the ADD and ADDDEF messages — its whole job is taking the domain mappings from the message and adding them into the hash table 🗂️ she's a team player fr fr.

for the actual deets on what the message format looks like, go peek at netlabel.h — that's where the description lives, not here 🙈

returns zero on success, and negative values on failure. that's it, that's the contract 💀
