🌸 SYNOPSIS 🌸

void cfg80211_michael_mic_failure (struct net_device *dev , const u8 *addr ,
                                   enum nl80211_key_type key_type , int key_id ,
                                   const u8 *tsc , gfp_t gfp );

like, that's the whole signature, copy it exactly, don't be weird about it 🫶

🧚 ARGUMENTS 🧚

  • dev — network device 🌈
  • addr — The source MAC address of the frame 👑
  • key_type — The key type that the received frame used 🔑
  • key_id — Key identifier (0..3). Can be -1 if missing. 🙈
  • tsc — The TSC value of the frame that generated the MIC failure (6 octets) ⭐
  • gfp — allocation flags 💜

💖 DESCRIPTION 💖

so this function gets called whenever the local MAC detects a MIC failure in a received frame — like, it's the moment the vibe check fails at the hardware level, bestie 😭

it matches with the MLME-MICHAELMICFAILURE.indication primitive. periodt. 🔥

ngl, that's the whole description on this one — no extra lore, no hidden flags, just the notification and the primitive it lines up with 🎀
