That looks weird. In this case wpa_supplicant runs in AP mode using WEP
security. However it looks like AUTH frame passed to the function
handle_auth (src/ap/ieee802_11.c) is completely broken.
Could you please provide some details about the platform in use, at least
hardware architecture and kernel version is use ? Maybe this is some kind
of endianness issue. Full wpa_supplicant verbose log would be useful
as well.
Regards,
Sergey
