STRUCT IWL_WOWLAN_GTK_STATUS_V2(9)

🎀 NAME 🎀

struct iwl_wowlan_gtk_status_v2 — GTK status, bestie. that's the whole thing. that's the assignment. 💅

(also real talk, this is from the Kernel API Manual, and the manual's own header is out here truncating the name to struct iwl_...tk_status_v2(9) like it's subtweeting it. the header bar has zero chill about long names. we move.)

---

✨ SYNOPSIS ✨

okay so here's the struct, and I'm handing it to you character-for-character because every single one of these is load-bearing:

       struct iwl_wowlan_gtk_status_v2 {
           u8 key[WOWLAN_KEY_MAX_SIZE];
           u8 key_len;
           u8 key_flags;
           u8 reserved[2];
           u8 tkip_mic_key[8];
           struct iwl_wowlan_rsc_tsc_params_cmd_ver_2 rsc;
        };

no cap, that's it. now let's meet the members one by one, group-chat style 🫶

🌸 Members 🌸

• key — the GTK material itself. the main character of the struct, honestly 👑
• key_len — GTK length. and hear me: if this is set to 0, the key is not available. no key, no vibe check, nothing to see here 😭
• key_flags — the tea about the key, served in bits:
  • 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. literally just padding. it's giving background character energy, let it live 🙈
• tkip_mic_key — TKIP RX MIC key
• rsc — TSC RSC counters

lowkey? read the kernel file in the source tree before you ship anything. the man page is the vibe, the header is the receipts.

okay that's the whole page, you ate that 💖 mwah. source-and-version sign-off time: this one comes to you from ./drivers/net/wireless/intel/i... (yes, cutely truncated, we respect the bit) and it's dated October 2026, filed under struct iwl_...tk_status_v2(9). slay, go forth and read structs 🌈⭐
