💅 Constants 💅

bestie, here are the constants in order — no skips, no “oops I forgot one”, we are doing all of them. ✨

  • IEEE80211_KEY_FLAG_GENERATE_IV_MGMT — the driver should set this for a CCMP/GCMP key when it needs IV generation only for management frames (MFP). 💖
  • IEEE80211_KEY_FLAG_GENERATE_IV — the driver should set this to say it needs IV generation for this particular key. lowkey important: setting this flag does not necessarily mean the SKBs will have sufficient tailroom for ICV or MIC. 🫶
  • IEEE80211_KEY_FLAG_GENERATE_MMIC — the driver should set this for a TKIP key if it needs Michael MIC generation done in software. 🧚
  • IEEE80211_KEY_FLAG_PAIRWISE — set by mac80211, this one means the key is pairwise rather than a shared key. 💫
  • IEEE80211_KEY_FLAG_SW_MGMT_TX — the driver should set this for a CCMP/GCMP key if it needs CCMP/GCMP encryption of management frames (MFP) to happen in software. 💅
  • IEEE80211_KEY_FLAG_PUT_IV_SPACE — the driver should set this if space should be prepared for the IV, but the IV itself should not be generated. ⚠️ Do not set this together with IEEE80211_KEY_FLAG_GENERATE_IV on the same key. Also, setting this flag does not necessarily mean the SKBs will have sufficient tailroom for ICV or MIC. 🌸
  • IEEE80211_KEY_FLAG_RX_MGMT — this key will be used to decrypt received management frames. The flag can help drivers that have a hardware crypto implementation that doesn't deal with management frames properly, by letting them not upload the keys to hardware and fall back to software crypto. note note note: this flag deals only with RX — if your crypto engine can't deal with TX, you can also set the IEEE80211_KEY_FLAG_SW_MGMT_TX flag to encrypt such frames in SW. 🦋
  • IEEE80211_KEY_FLAG_RESERVE_TAILROOM — the driver should set this for a key to indicate that sufficient tailroom must always be reserved for ICV or MIC, even when HW encryption is enabled. 👑
  • IEEE80211_KEY_FLAG_PUT_MIC_SPACE — the driver should set this for a TKIP key if it only requires MIC space. ⚠️ Do not set this together with IEEE80211_KEY_FLAG_GENERATE_MMIC on the same key. 🍓
  • IEEE80211_KEY_FLAG_NO_AUTO_TX — key needs explicit Tx activation. periodt. 💀
  • IEEE80211_KEY_FLAG_GENERATE_MMIE — the driver should set this for an AES_CMAC or an AES_GMAC key to indicate that it requires sequence number generation only. 🌈
  • IEEE80211_KEY_FLAG_SPP_AMSDU — SPP A-MSDUs can be used with this key (set by mac80211 from the sta->spp_amsdu flag). 💜

🌟 Description 🌟

These flags are used for communication about keys between the driver and mac80211, with the flags parameter of struct ieee80211_key_conf. 🫶✨
