Thanks. It looks like there is something quite badly wrong in whatever
is translating these messages between the authentication server and the
EAP peer implementation from wpa_supplicant. Based on the certificate
names, I would assume this is using WiMAX and some kind of translation
of EAP information from there into wpa_supplicant code. This code is not
included in the wpa_supplicant repository nor have I seen it, so I
cannot provide more comments on what could be wrong there.
I would suggest checking the translation glue code between WiMAX and EAP
peer. It seems to be sending most EAP messages multiple times (id=1
once, id=2 twice, id=3 thrice, id=4 at least four times)..
Is the WiMAX glue code that is used here something that is available
under an open source license (or could be released as such)?
