📦 version 7.3.1, in nixpkgs unstable

💖 netlbl_unlhsh_add_addr6(9) 💖

okay so bestie, welcome to the Kernel API Manual section for netlbl_unlhsh_add_addr6 — yes that's the whole manual name, we're in kernel-land now, no cap. This one is a lil function in ./net/netlabel and she's here to add IPv6 address entries to a hash table. iykyk. 🦋

✨ NAME ✨

netlbl_unlhsh_add_addr6 — add a brand-new IPv6 address entry to the hash table</p> 🎀

🌸 SYNOPSIS 🌸

int netlbl_unlhsh_add_addr6 (struct netlbl_unlhsh_iface *iface , const
       struct in6_addr *addr , const struct in6_addr *mask , u32 secid );

she takes four arguments and gives you back an int, that's the whole vibe. 💅

🦋 ARGUMENTS 🦋

  • iface — the associated interface entry. like, the interface she's gonna attach this address to. 🌈
  • addr — the IPv6 address, in network byte order. yes, network byte order, don't come at me with host order, that's a different situation entirely. 😭
  • mask — the IPv6 address mask, also in network byte order. same rules bestie. ✨
  • secid — the LSM secid value for the entry. it's a u32, she's little but she matters. 👑

💜 DESCRIPTION 💜

so what she actually does: she adds a new address entry into the unlabeled connection hash table, using the interface entry you passed in as iface. that's it, that's the job. 🫶

On success she returns zero — slay. Otherwise she returns a negative value, which is your sign that something did not go to plan, and you should probably go look at the return code instead of ignoring it. 🙈

ngl bestie, no zero-return means no happy ending. check your negative value fr fr. 💀

and the whole friend group, all in section (9), all present and accounted for:

like, that's the entire group chat, bestie. every single one of them. 🔥

and that's the page!! 💖 this iconic lil number lives under ./net/netlabel and she's dated October 2026 — so go add those IPv6 entries, return your zero, and remember: network byte order always. periodt. 👑🎀🌸
