nla_parse_nested_deprecated(9)

💅 nla_parse_nested_deprecated — Kernel API Manual, bestie edition ✨

okay so bestie, welcome to nla_parse_nested_deprecated 💖 this one lives in the Kernel API Manual section 9, and it's lowkey a little shy — the whole description is basically a "go ask my sibling" moment. Anyway, let's get into it 🫶

🌸 NAME 🌸

nla_parse_nested_deprecated — parse nested attributes ✨

🎀 SYNOPSIS 🎀

int nla_parse_nested_deprecated (struct nlattr *tb[] , int maxtype ,
       const struct nlattr *nla , const struct nla_policy *policy , struct
       netlink_ext_ack *extack );

like, yes, that's a lot of arguments, but we're gonna walk through them one by one, no cap 💅

👑 ARGUMENTS 👑

• tb — the destination array, and it needs maxtype+1 elements. count them properly bestie, the +1 is not decorative 🍓
• maxtype — the maximum attribute type you're expecting to see. the ceiling. the limit. the "don't come at me with anything bigger than this" 💀
• nla — the attribute that's holding all the nested attributes inside it. it's giving "bag full of smaller bags" 🎀
• policy — the validation policy. the rules of the group chat 📜
• extack — the extended ACK report struct. this is where the receipts get written if something goes wrong 🧾

🦋 DESCRIPTION 🦋

See nla_parse_deprecated.

...that's it. that's the whole thing. i'm not even joking 😭 bestie the manpage literally just points you at nla_parse_deprecated and dips. iconic behaviour honestly, main character energy of the highest order 👑 but fr fr go read that one, it's got the actual scoop.

and that's the whole page babes 💜 it came from ./include/net, dropped October 2026, and it's the nla_parse_nested_deprecated(9) page — short, sweet, and fully delegating 😭💅 go read nla_parse_deprecated and slay ✨🌷
