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. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
