OK. This looks like some kind of bug in the supplicant, but I would like
to confirm that that is indeed the case.

The debug log you sent previously had some of the long lines truncated
and made it difficult for me to manually parse the messages from the
supplicant. As such, I could not easily figure out why there would be
any difference between hostapd and FreeRADIUS as the authentication
If you can easily generate that same error case, i.e., "EAP-PEAP: Length
mismatch in Phase 2 EAP frame (len=75
hdr->length=76)", I would be interested in seeing a complete debug log
from hostapd (-ddK on command line) with all information included. This
is especially needed for the hexdumps of the messages that got
truncated for longer packets.
