ff4a6d4382 EAP-SIM/AKA: Explicitly check for header to include Reserved field
This was previously checked as part of the eap_sim_parse_attr()
processing, but it is easier to review the code if there is an
additional explicit check for confirming that the Reserved field is
present since the pos variable is advanced beyond it.

f534ee0804 EAP peer: Clear keying material on deinit
Reduce the amount of time keying material (MSK, EMSK, temporary private
data) remains in memory in EAP methods. This provides additional
protection should there be any issues that could expose process memory
to external observers.

28bfa29117 EAP-AKA: Remove unnecessary dead increment
The pos pointer is not used after this now nor in future plans, so no
need to increment the value. This remove a static analyzer warning about
dead increment.

05c79d6acd EAP-SIM/AKA: Use os_memcmp_const() for hash/password comparisons
This makes the implementation less likely to provide useful timing
information to potential attackers from comparisons of information
received from a remote device and private material known only by the
authorized devices.

b2b8a4cb10 EAP-SIM/AKA: Pass EAP type as argument to eap_sim_msg_finish()
This makes it easier for static analyzers to figure out which code paths
are possible within eap_sim_msg_finish() for EAP-SIM. This will
hopefully avoid some false warnings (CID 68110, CID 68113, CID 68114).

db13605816 EAP-AKA/AKA' peer: Allow external USIM processing to be used
This allows the new external_sim=1 case to be used to perform UMTS
authentication step in EAP-AKA/AKA' peer process. Following control
interface event is used to request the operation:

CTRL-REQ-SIM-<network id>:UMTS-AUTH:<RAND>:<AUTN> needed for SSID <SSID>

Response from external processing is returned with
CTRL-RSP-SIM-<network id> UMTS-AUTH:<IK>:<CK>:<RES>
or
CTRL-RSP-SIM-<network id> UMTS-AUTS:<AUTS>

e026159a8e EAP-SIM/AKA: Store pseudonym identity in configuration
Use the anonymous_identity field to store EAP-SIM/AKA pseudonym identity
so that this can be maintained between EAP sessions (e.g., after
wpa_supplicant restart) even if fast re-authentication data was cleared.

762e4ce620 EAP-AKA': Update to RFC 5448
There was a technical change between the last IETF draft version
(draft-arkko-eap-aka-kdf-10) and RFC 5448 in the leading characters
used in the username (i.e., use unique characters for EAP-AKA' instead
of reusing the EAP-AKA ones). This commit updates EAP-AKA' server and
peer implementations to use the leading characters based on the final
RFC.

Note: This will make EAP-AKA' not interoperate between the earlier
draft version and the new version.

This fixes an issue where two AKA'/Challenge messages are received when
resynchronizing SEQ#. Previously, this used to trigger an authentication
