[patch] bug in a management of multiple ssid

Reported by: Assigned to:

Component: madwifi: 802.11 stack Version: v0.9.4

Patch is attached: 1 Pending: 0


There is a serious bug in the management of multi-ssid. When a station is associated with one of ssid, the 802.11 packets sent from the station and received to the physical device (wifiX) are directed toward the virtual interface you associate (athX) without checking the destionation mac address. All packets, regardless if they are broadcast or they are directed to an access point (even those not directed to the ssid associated), are sent to the virtual interface associated. When the station is associated with one of ssid available, the broadcast 802.11 PROBE REQUEST are addressed exclusively with vap associated. If the station fails to send the 802.11 DISASSOCIATION, it can no longer associate with another ssid. Messages 802.11 AUTH/ASSOC continue to be addressed to the previous ssid.

I have attached the patch that fixes the problem.

Ciao Massimo
