Hi,
We're getting reports of weird behavior on ath9k/mac80211 devices when
CONTROL_PORT_FRAME support is used. iwlwifi, works fine under the same
circumstances. If CONTROL_PORT_FRAME is disabled and the old legacy PAE
transport is used, everything works fine.
The short version:
- We Connect with MFP enabled
- Handshake packet 1 & 2 is exchanged
- Handshake packet 3 is received & reply sent
- Keys are set
- AP never receives our packet 4, or the card drops it locally
- Subsequent retransmissions are sent un-encrypted by the AP and are
probably sent encrypted (via MFP) by mac80211. Since the driver never
sets NO_ENCRYPT flag, userspace has no knowledge to try and send the
reply un-encrypted.
Here's a log (some parts are removed for brevity, but if someone wants
the full log, I can provide this as well):

Here comes the Handshake packet 1 from the AP. Why the hell is it here
prior to Authenticate ? But whatever ;)
