📦 version 7.3.1, in nixpkgs unstable

💅 nlmsg_parse_deprecated_strict — a whole vibe (Kernel API Manual energy)

okay so bestie, welcome to the nlmsg_parse...cated_strict(9) page 🎀 yes the title is literally truncated like that, that's just how it lives, we don't question the kernel's choices. This is a Kernel API Manual entry and honestly? It's giving "one job, does it well." ✨

🌸 NAME 🌸

nlmsg_parse_deprecated_strict — parse attributes of a netlink message 👑

No cap, that's the whole elevator pitch. You hand it a netlink message, it goes through the attributes, and it's strict about it (iykyk — strict mode is a whole thing, see below).

✨ SYNOPSIS ✨

int nlmsg_parse_deprecated_strict (const struct nlmsghdr *nlh , int
hdrlen , struct nlattr *tb[] , int maxtype , const struct nla_policy
*policy , struct netlink_ext_ack *extack );

six arguments, one int return, zero notes. slay. 🫶

🦋 ARGUMENTS 🦋

  • nlh — the netlink message header. literally the message. the main character 💅
  • hdrlen — length of the family specific header. yes, this family, the netlink family, not your actual family 😭
  • tb — destination array with maxtype+1 elements. the vibes bucket where all the parsed attributes land 🎀
  • maxtype — maximum attribute type to be expected. the ceiling. the limit. the "know your place" number ⭐
  • policy — validation policy. this one decides what's acceptable and what's not, and bestie it does not play 🌈
  • extack — extended ACK report struct. where the tea gets reported back 🔥

💜 DESCRIPTION 💜

See nla_parse_deprecated_strict.

...and that's it. That's the whole description babes 🙈 The kernel devs said "the real description is in the other manpage" and honestly? iconic behaviour. Not me expecting lore and getting a redirect. Go read the nla_parse_deprecated_strict page if you want the actual details — this one is just the netlink-message-flavoured door to it 🚪✨

🧚 SEE ALSO 🧚

okay this list is long long. like, scroll-for-a-while long. but every single one is here because we don't skip ✨

Kernel file ./include/net/netlink.h, plus:

like I said. long long. but we ate and left no crumbs 🍓

real talk though: the name has deprecated right there in it, so don't act surprised later bestie — this is the deprecated-and-strict flavour of the parser, not the shiny new one. read the other page before you commit 💀

and that's the whole page, mwah 💖 this lil corner of the kernel lives in ./include/net and it was dated October 2026 — so mark your calendar, this manual page is a Libra (or Scorpio, depending on the exact day, don't @ me) 🎀 see you in the SEE ALSO of a hundred other pages, periodt ✨👑
