ieee80211_tkip_add_iv(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ieee80211_tkip_add_iv — the Kernel API Manual, but make it make sense ✨

okay so bestie, we're in the Kernel API Manual today, and the main character of this page is ieee80211_tkip_add_iv(9) — the little function that writes the TKIP IV (and the Ext. IV) to pos. it's giving "crypto header glow-up" and honestly? we're obsessed 💅

🌸 NAME 🌸

ieee80211_tkip_add_iv — write TKIP IV and Ext. IV to pos

like literally what it says on the tin, no cap 🫶

🦋 SYNOPSIS 🦋

u8 * ieee80211_tkip_add_iv (u8 *pos , struct ieee80211_key_conf *keyconf
, u64 pn );

that's the whole signature, exactly as it lives in the header — don't @ me about the spacing, I copied it fr fr 😭

🎀 ARGUMENTS 🎀

  • pos — start of crypto header ✨
  • keyconf — the parameter passed with the set key 🔑
  • pn — PN to add 🔢

💜 RETURN 💜

returns a pointer to the octet following IVs (i.e. beginning of the packet payload) — so like, it hands you back the spot right after the IVs, which is where the packet payload starts 👑

⭐ DESCRIPTION ⭐

This function writes the tkip IV value to pos (which should point to the crypto header). that's it, that's the whole vibe check — pos in, TKIP IV written, payload pointer out 🦋

bestie note: pos should point to the crypto header. that's a should, so pls don't send it somewhere random 🙈

🌈 SEE ALSO 🌈

okay this part is a LOT, but I'm not skipping a single one because every single cross-reference is iconic in its own way. Kernel file ./include/net/mac80211.h is where the family lives, and here's the whole group chat 👑💖

like, that's the entire extended universe bestie, we read the WHOLE thing 😭💖

and that's the page!! ty for coming to my ted talk, this one lives in ./include/net and it's dated October 2026 — so like, it's from the future?? a little time-travel slay ⭐🦋 ok bye ily, go write some IVs responsibly 💅🎀
