Subject[ 049/122] mac80211: fail authentication when AP denied authentication
Date
From: Greg KH <gregkh@linuxfoundation.org>

3.5-stable review patch. If anyone has any objections, please let me know.

------------------

From: Eliad Peller <eliad@wizery.com>

commit dac211ec10d268b9d09000093a9fa2ac1773894f upstream.

ieee80211_rx_mgmt_auth() doesn't handle denied authentication
properly - it authenticates the station and waits for association
(for 5 seconds) instead of failing the authentication.

Fix it by destroying auth_data and bailing out instead.
