Description Adrian Chadd freebsd_committer 2013-05-06 23:10:00 UTC
When UDP iperf transmit is going on, a WPA group rekey fails and the AP ditches the station.

What's going on:

* FreeBSD AP -> FreeBSD STA (both ath)
* AP sends a WPA rekey EAPOL message to the STA
* STA updates the key, sends an EAPOL message back
* AP doesn't get it, so it eventually disconnects the station.

What's breaking:

* The STA gets the EAPOL group rekey frame
* the STA updates the keycache entry
* The STA sends the EAPOL response
* .. but it doesn't actually send the frame, it gets dropped by ath_start() because the buffers are all allocated.

I'll dig into it some more.
