STRUCT IWL_SEC_KEY_CMD(9)

💖 struct iwl_sec_key_cmd — security key command 💖

okay bestie so this is a page straight out of the Kernel API Manual (yes, the kernel has lore) and today's main character is struct iwl_sec_key_cmd, the security key command. it's giving "i hold your keys and i'm not sorry." 🔑✨

---

🌸 NAME 🌸

struct iwl_sec_key_cmd — security key command. that's it, that's the vibe. she's a struct, she carries key commands, she slays.

---

✨ SYNOPSIS ✨

okay look at her. look at the anatomy. the way she's built 🫶

struct iwl_sec_key_cmd {
    __le32 action;
    union {
      struct {
        __le32 sta_mask;
        __le32 key_id;
        __le32 key_flags;
        u8 key[32];
        u8 tkip_mic_rx_key[8];
        u8 tkip_mic_tx_key[8];
        __le64 rx_seq;
        __le64 tx_seq;
      } add;
      struct {
        __le32 old_sta_mask;
        __le32 new_sta_mask;
        __le32 key_id;
        __le32 key_flags;
      } modify;
      struct {
        __le32 sta_mask;
        __le32 key_id;
        __le32 key_flags;
      } remove;
    } u;
 };

so there's action, and then there's u — the union that switches up its whole personality depending on which command type you're running. add, modify, remove. three little eras, one union. iconic. 💅

🎀 Members 🎀

• action — the action, pulled from enum iwl_ctxt_action. she decides which member of the union gets to shine. ✨
• u — the union itself, and which face she's wearing totally depends on the command type. union depending on command type, periodt.
• u.add.sta_mask — station mask for the new key 💫
• u.add.key_id — key ID (0-7) for the new key. yes, 0-7, no cap, that's the range 🔢
• u.add.key_flags — key flags, per enum iwl_sec_key_flags
• u.add.key — the actual key material. ⚠️ heads up: WEP keys should start from IWL_SEC_WEP_KEY_OFFSET. don't forget the offset, bestie, you'll have a bad time 😭
• u.add.tkip_mic_rx_key — TKIP MIC RX key
• u.add.tkip_mic_tx_key — TKIP MIC TX key
• u.add.rx_seq — RX sequence counter value
• u.add.tx_seq — TX sequence counter value

like, the add era is the full glam: keys, mics, sequences, she has everything. 💅

• u.modify.old_sta_mask — old station mask (the before picture 📸)
• u.modify.new_sta_mask — new station mask (the glow-up ✨)
• u.modify.key_id — key ID
• u.modify.key_flags — new key flags
• u.remove.sta_mask — station mask
• u.remove.key_id — key ID
• u.remove.key_flags — key flags

and remove is the minimalist era: mask, key ID, flags, bye 👋 the way she's so much shorter than add... it's giving "we don't do extra here."

ngl the u.add.key WEP offset thing is the one you'll actually trip over. IWL_SEC_WEP_KEY_OFFSET. write it on your hand. fr fr. 💀
