STRUCT KEY_PARAMS(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual — we're looking at struct key_params(9) and it's literally the info packet for a key. it's giving “everything you need to know about this key” energy, no cap. 💖

✨ NAME ✨

struct key_params — key information. short, iconic, to the point. that's the name, periodt. 🎀

🌸 SYNOPSIS 🌸

here's the whole struct, bestie — exact copy, no edits, no vibes-based rewriting:

       struct key_params {
           const u8 *key;
           const u8 *seq;
           int key_len;
           int seq_len;
           u16 vlan_id;
           u32 cipher;
           enum nl80211_key_mode mode;
           const u8 *ltf_keyseed;
           size_t ltf_keyseed_len;
        };

💅 Members 💅

okay, member by member, because every field is a main character:

  • key — key material. literally the key stuff, bestie. 🔑
  • seq — sequence counter (IV/PN), must be in little endian, length given by seq_len. this one has rules, so don't play with endianness. ⚠️
  • key_len — length of key material.
  • seq_len — length of seq.
  • vlan_id — vlan_id for VLAN group key (if nonzero). yes, the field is named the same as the thing it is. iconic. 💅
  • cipher — cipher suite selector.
  • mode — key install mode (RX_TX, NO_TX or SET_TX). those are the three modes, periodt.
  • ltf_keyseed — LTF key seed material.
  • ltf_keyseed_len — length of LTF key seed material.

🎀 Description 🎀

Information about a key. that's the whole description, bestie — short and sweet, says exactly what it needs to. this struct is the vibe check for a key: all the info, none of the fluff. 💖

💫 SEE ALSO 💫

okay bestie, this SEE ALSO list is literally the whole group chat of cfg80211 pages — every single one is invited, no skips, no “seen at 2:14am” energy. Here’s the full roster in order 🫶✨

…and the see-also cinematic universe keeps going, bestie, no cap. Here's the rest of the list — same energy, every single entry intact:

Okay so that's genuinely the whole thing. Sixty-four cross-references, zero skips, iykyk. Go click through them, your future self will thank you 🦋

That's a wrap on struct key_params(9)! This lil slice lives in ./include/net, dated October 2026, and the page signs off as struct key_params(9) — so if you ever need to cite it, that's your receipt. Now go forth and key your params responsibly, bestie 💖✨
