STRUCT IWL_WOWLAN_GTK_STATUS_V3(9)

💖 struct iwl_wowlan_gtk_status_v3(9) — Kernel API Manual 💖

okay so bestie, this is a page straight outta the Kernel API Manual, and the star of the show is struct iwl_wowlan_gtk_status_v3 — a GTK status struct, and honestly? it's giving "small but mighty" ✨

---

🌸 NAME 🌸

struct iwl_wowlan_gtk_status_v3 — GTK status, no cap 💅

---

🦋 SYNOPSIS 🦋

like, here's literally the whole shape of it:

struct iwl_wowlan_gtk_status_v3 {
    u8 key[WOWLAN_KEY_MAX_SIZE];
    u8 key_len;
    u8 key_flags;
    u8 reserved[2];
    u8 tkip_mic_key[IWL_MIC_KEY_SIZE];
    struct iwl_wowlan_all_rsc_tsc_v5 sc;
 };

she's compact, she's got one job, and she ate 🔥

---

🎀 Members 🎀

okay let's go field by field, bestie, because every single one matters:

• key — the GTK material itself 💖 (the actual bytes, the moment, the main character)
• key_len — the GTK length. but listen: if it's set to 0, the key is not available. like, it's just not there, periodt 🙈
• key_flags — the little info bundle about the key, and the bits are doing very specific things:
  • bits[0:1]: key index assigned by the AP
  • bits[2:6]: GTK index of the key in the internal DB
  • bit[7]: Set iff this is the currently used GTK 👑
• reserved — padding, just vibing in the corner 🫶
• tkip_mic_key — the TKIP RX MIC key
• sc — RSC/TSC counters ⭐

lowkey a reminder that this page describes the layout exactly as written — don't go renaming fields or "improving" the bit ranges, bestie, the firmware is literally counting on you 🙏
