Thank you for your reply.
Yes, you are right, iwr->u.data.length and sizeof(wpaie) in the beginning of
ieee80211_ioctl_getwpaie() in MadWifi are not the same size without your
patch.
Now there is no "Failed to get WPA/RSN IE" error message to apply your
patch, but my client still can't connect to the ap. Some of the debug
message is as below. The message is too big, so please refer to the
attachment for the all message.
Thank you.
