-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.
