The AP rejects the FILS-IM association request with reason
"Invalid IE format". In the assoc request, two problems are
seen:
1. The RSN IE has a junk group management cipher suite.
2. FILS HLP container IE is fragmented, and the fragment
IE does not immediately follow the HLP container IE.
In the assoc request, the RSN IE encoded in the authentication
is unpacked and the PMKID is replaced with the pmkr1 name
derived at the end of FILS authentication. Currently, the
existing PMKID in the RSN IE is replaced only if the group
management cipher is present. In non-802.11w case, the new
PMKID is appended at the end of existing PMKID, and leads to
improper IE format.
To fix this, replace the existing PMKID whenever PMKID is
present.
To fix invalid HLP container IE format, encode the HLP
container and its fragment IEs together in the assoc request.
Also, inorder to get the pmksa match from the crypto table for
a FT-FILS, fill both ssid and cache ID. Without cache id, the
cached entry is not updated with MDIE.
