Subject: [PATCH 8/8] FT: Do not allow multiple Reassociation Response frames
|
|
|
|
The driver is expected to not report a second association event without
|
|
the station having explicitly request a new association. As such, this
|
|
case should not be reachable. However, since reconfiguring the same
|
|
pairwise or group keys to the driver could result in nonce reuse issues,
|
|
be extra careful here and do an additional state check to avoid this
|
|
even if the local driver ends up somehow accepting an unexpected
|
|
Reassociation Response frame.
