From 8c07fa9eda13e835f3f968b2e1c9a8be3a851ff9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] AP: Silently ignore management frame from unexpected source
address
Do not process any received Management frames with unexpected/invalid SA
so that we do not add any state for unexpected STA addresses or end up
sending out frames to unexpected destination. This prevents unexpected
sequences where an unprotected frame might end up causing the AP to send
out a response to another device and that other device processing the
unexpected response.
In particular, this prevents some potential denial of service cases
where the unexpected response frame from the AP might result in a
connected station dropping its association.
