💖 netlbl_af6list_search_exact — like, the search for an EXACT IPv6 address entry 💖

okay so bestie, this is a page straight out of the Kernel API Manual (yes, the kernel has a manual, and yes it's kind of iconic), and today's main character is netlbl_af6list_search_exact. no cap, it does exactly one thing and it does it slayfully. let's get into it 🫶

✨ NAME ✨

netlbl_af6list_search_exact — Search for an exact IPv6 address entry 🌸

---

🦋 SYNOPSIS 🦋

struct netlbl_af6list * netlbl_af6list_search_exact (const struct
in6_addr *addr , const struct in6_addr *mask , struct list_head *head );

like, that's the whole signature, copy-pasted with love 💅

---

🎀 ARGUMENTS 🎀

• addr — the IPv6 address, the literal address of the situation 👑
• mask — the IPv6 address mask, its ride-or-die 💜
• head — the list head, aka where the whole list starts, the main character energy of the data structure 🌟

---

💀 DESCRIPTION 💀

so basically it searches the IPv6 address list given by head. 🔍 if an exact match is found, it gets returned — like, "here's your entry, bestie" 🎁 — otherwise NULL is returned, which is the kernel's way of saying "sorry babe, nothing here" 😭.

⚠️ real talk though: the caller is responsible for calling the rcu_read_[un]lock functions. that's on YOU, not on this function. do not skip it, fr fr, the RCU lock is not a vibe you can just ignore 🙈
