If two BSS entries have the same HESSID and SSID, share the fetched ANQP
information between these BSS entries to save memory and GAS/ANQP
operations.

The eap parameter in the cred block can now be used to override
automatic EAP-SIM/AKA/AKA' selection.

This is an initial step in allowing the ANQP responses to be shared
among multiple BSSes if the BSSes are determined to be operating under
identical configuration.

If the REMOVE_NETWORK command is used to delete the currently connected
network, some operations were run between removing the network and
clearing of wpa_s->current_ssid. This left wpa_s->current_ssid pointing
to freed memory and should any operation end up using it before the
pointer gets cleared, freed memory could be references. Avoid this by
removing the network only after having completed the operations that
clear wpa_s->current_ssid.

Use configured credentials to figure out which ANQP information needs to
be fetched and only fetch those when using Interworking network
selection. The fetch_anqp command is still fetching all ANQP
information.

If the scan results from before ANQP fetch are fresh (less than five
seconds old), do not run a new scan when selecting the BSS after having
used Interworking network selection.
Signed-hostap: Jouni Malinen <j@w1.fi>
This allows the BSS selection functions to be called without having the
scan result data structure. This can be used to skip extra scans in
cases where previous results can be considered fresh.
Signed-hostap: Jouni Malinen <j@w1.fi>
This allows last results to be used even after they have been freed
since the information is copied to the BSS entries anyway and this new
array provides the order in which scan results were processed.
Signed-hostap: Jouni Malinen <j@w1.fi>
The same information is available in the BSS table, so we can reduce the
need for using the raw scan results in wpa_supplicant_need_to_roam().

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.

The EAP-SIM/AKA code is already validating the prefix and the following
lookup would not find matches if the prefix is incorrect, so there is no
need for the extra checks here.

If EAP-Response/Identity includes a known pseudonym or re-auth username,

These fields are used only as the search key, so the value is already
known and does not need to be copied from the database.

Store permanent username (i.e., including prefix character) instead of
IMSI in the SQLite DB. Convert the string to a string since the EAP-AKA
prefix can start with zero. This cleans up the field names since the
value was already with the prefix included instead of just IMSI. In
addition, this explicitly removes some theoretical cases where the
different identity types could have been mixed.
Signed-hostap: Jouni Malinen <j@w1.fi>
Since the EAP-SIM/AKA identities are ASCII strings, there is no need to
use more complex way for storing and passing them. In addition, be more
strict about enforcing username (i.e., no realm part) to be used in the
EAP-SIM DB API. Similarly, require specific username type instead of any
of the types to be used as the key in the pseudonym and reauth
operations. This allows simpler lookup operations to be used.

Since we always request an identity in the request, the response
has to include AT_IDENTITY. This allows the AKA/Identity response
processing to be simplified a bit.

There is no need to use eap_sim_db_identity_known() here since a new
AKA/Identity message is built only if the identity in the previous

AT_ANY_ID_REQ to meet the RFC 4187 recommendation on EAP method specific
identity request.

Commit 0d30cc240f forced
wpa_s->current_ssid to be cleared in wpa_supplicant_mark_disassoc()

Commit 0d30cc240f forced
wpa_s->current_ssid and wpa_s->key_mgmt to be cleared in
wpa_supplicant_mark_disassoc() which gets called from
wpa_supplicant_event_disassoc(). This broke IEEE 802.1X authentication
failure processing and P2P deauthentication notification (group
termination).
Fix this by splitting wpa_supplicant_event_disassoc() into two parts and
make wpas_p2p_deauth_notif() indicate whether the interface was removed.
If so, the last part of disassocition event processing is skipped. Since
the wpa_supplicant_mark_disassoc() call is in the second part, the above
mentioned issues are resolved. In addition, this cleans up the P2P group
interface removal case by not trying to use fast reconnection mechanism
just before the interface gets removed.

The wpa_s->current_ssid pointer may get cleared, e.g., when
disconnected. Commit 30ee769235 made
wpas_p2p_group_delete() exit early before removing a P2P interface in
this type of case. That can cause number of issues from p2p_group_remove
command failing to busy loop when terminating wpa_supplicant if there is
a P2P group interface in client mode and that interface happens to be in
disconnected state. Fix these issues by allowing wpas_p2p_group_delete()
remove the P2P group interface regardless of whether wpa_s->currnt_ssid
is set.
