fm10k_tlv_attr_validate(9)

📦 version 7.3.1, in nixpkgs unstable

💅 fm10k_tlv_attr_validate(9) — like, the kernel API manual bestie 🎀

okay so first things first: this page lives in the Kernel API Manual (manual name fm10k_tlv_attr_validate(9), yes the title is literally the section, iconic), and it's all about one lil' function that does a vibe check on your TLV attributes before the rest of the driver has to deal with them. no cap. 🦋

✨ NAME ✨

fm10k_tlv_attr_validate — Validate attribute metadata 👑

🌸 SYNOPSIS 🌸

s32 fm10k_tlv_attr_validate (u32 *attr , const struct fm10k_tlv_attr
*tlv_attr );

literally just that. two args, one s32 coming back at you. 💖

🫶 ARGUMENTS 🫶

  • attr — Pointer to attribute. that's your actual attribute data, the thing getting inspected 💅
  • tlv_attr — Type and length info for attribute. like, the metadata that tells you what attr is supposed to be 🌸

🔥 DESCRIPTION 🔥

So what does this function actually do? It does some basic validation of the input TLV — a little starter vibe check, nothing extra. 🧚

It verifies the length, and in the case of null terminated strings it verifies that the last byte is null. yes bestie, that last byte. the final one. it has ONE job and it's checking that byte is null. 😭

The function will return FM10K_ERR_PARAM if any attribute is malformed, otherwise it returns 0. so like — 0 means slay, FM10K_ERR_PARAM means something's busted. periodt. 💀

fr fr, that's the whole function. small, focused, does its little job. main character energy in a single-purpose way. 👑

🌈 SEE ALSO 🌈

the kernel file lives at ./drivers/net/ethernet/intel/fm10k/fm10k_tlv.c and honestly the whole TLV friend group shows up here, so lemme introduce you:

okay that's the whole page bestie, go validate some attributes 💜✨
