genlmsg_parse_deprecated(9)

💅 genlmsg_parse_deprecated(9) — from the Kernel API Manual, bestie

okay so picture this: it's a genlmsg_parse_deprecated(9) kind of day — that's the kernel manual page we're doing, and yes the "deprecated" in the name is right there being all ominous, we'll get to it. sit down, grab a strawberry 🍓, and let's parse some attributes together.

---

✨ NAME ✨

genlmsg_parse_deprecated — the one that parses the attributes of a genetlink message 🎀 (yes, that genetlink message, the one your family is gossiping about)

---

🌸 SYNOPSIS 🌸

int genlmsg_parse_deprecated (const struct nlmsghdr *nlh , const struct
genl_family *family , struct nlattr *tb[] , int maxtype , const struct
nla_policy *policy , struct netlink_ext_ack *extack );

like, that's the whole signature, no notes 💅

---

🦋 ARGUMENTS 🦋

okay bestie, six things going in, keep up:

• nlh — the netlink message header. the main character of this whole operation, ngl 👑
• family — the genetlink message family. it's giving "who even are you" energy, in the good way 🫶
• tb — destination array with maxtype+1 elements. yes, plus one, do not forget the plus one, this is fr fr the classic off-by-one trap 🙈
• maxtype — maximum attribute type to be expected. the vibes ceiling ⭐
• policy — validation policy. she checks your outfit before you leave the house and honestly? iconic 💖
• extack — extended ACK report struct. the receipts 🔥

mwah 💜 that's the page!! this one lives in ./include/net and the manual beeped into existence in October 2026 — so go forth, parse those attributes, and remember: maxtype+1 elements, bestie, always 💅✨
