270c9a43e6 Interworking: Allow FT to be used for connection
This extends Interworking network selection to enable FT-EAP as an
optional key_mgmt value to allow FT to be used instead of hardcoding
WPA2-Enterprise without FT.

13f6a07efc Add SIM identifier to the network profile and cred block
This allows the specific SIM to be identified for authentication
purposes in multi-SIM devices. This SIM number represents the index of
the SIM slot. This SIM number shall be used for the authentication using
the respective SIM for the Wi-Fi connection to the corresponding

b7fb98f072 Interworking: Fix already-connected check to verify network priority
Commit d28f4e44f1 optimized Interworking
network selection in a case where the operation is run while already
connected to the selected network by skipping the reconnection. However,
this did not take into account that a higher priority network may have
shown up in the new scan results.

Fix this by checking whether network selection based on the latest scan
results (the ones from the interworking_select operation) would result
in a network with higher priority being selected. If so, skip the
optimization and force normal network connection (which will select this
newly found higher priority network). This fixes cases where a
non-Hotspot 2.0 network with higher priority (e.g., home network) shows
up while connected to a Hotspot 2.0 network with lower priority.

3d910ef497 Interworking: Prefer last added network during network selection
Previously, any network block could be used to select the BSS to connect
to when processing scan results after Interworking network selection.
This can result in somewhat unexpected network selection in cases where
credential preferences indicated that a specific network was selected,
but another network ended up getting used for the connection. While the
older networks continue to be valid, add special processing for this
initial post-interworking-connect case to get more consistent network
selection to match with the Interworking network selection result.

6ede8a7e4d Interworking: Avoid duplicated network blocks
Do not add multiple network blocks for the same network from a single
credential. INTERWORKING_CONNECT used to generate a new network block
for each instance regardless of what network blocks have already been
configured. While this allows the connection to go through, it is not
efficient to leave behind potentially large number of network blocks
with the same contents (or worse, changed contents). Address this by
removing an older network block for the same credential before adding a
new one.

0b9d3b22c8 Interworking: Relax 3GPP info PLMN matching for MNC
3GPP TS 24.232 Annex A.3 allows network operator to advertise only two
digits of MNC even if MNC has three digits. Allow such matches in

MNC length was assumed to be two to avoid missing networks if MNC length
cannot be determined reliably. Remove the '-' separator from simulated
SIM/USIM cases to allow the new matching rules to work.

Fix the PLMN List information element parsing loop to use the length of
the PLMN List instead of the length of the full 3GPP Cellular Info to
avoid unexpected matches should a new element ever be added by 3GPP.

Finally, add more debug prints from PLMN matching to make the logs

0dd5431312 Do not inform other virtual interfaces of scan results in all cases
If a connection operation is started on an interface based on scan
results, other virtual interfaces should not be information about the
results to avoid potential concurrent operations during the association
steps. Since the sibling notification of scan results received was added
as an optimization, skipping it for this type of cases is the simplest
way of avoiding unnecessary concurrent operations.

b1f122964e Add generic GAS request mechanism
The new gas_request and gas_response_get commands can be used to request
arbitary GAS queries to be performed. These can be used with ANQP or
with other (including vendor specific) advertisement protocols.

gas_request <BSSID> <AdvProtoID> [Query]
gas_response_get <addr> <dialog token> [offset,length]

For example, ANQP query for Capability list in interactive wpa_cli
session:

> gas_request 02:00:00:00:01:00 00 000102000101
<3>GAS-RESPONSE-INFO addr=02:00:00:00:01:00 dialog_token=0
status_code=0 resp_len=32
> gas_response_get 02:00:00:00:01:00 00
01011c00010102010501070108010c01dddd0c00506f9a110200020304050607
> gas_response_get 02:00:00:00:01:00 00 0,10
01011c00010102010501
> gas_response_get 02:00:00:00:01:00 00 10,10

> gas_response_get 02:00:00:00:01:00 00 20,10
506f9a11020002030405
> gas_response_get 02:00:00:00:01:00 00 30,2
0607

It should be noted that the maximum length of the response buffer is
currently 4096 bytes which allows about 2000 bytes of the response data
to be fetched with a single gas_response_get command. If the response is
longer, it can be fetched in pieces as shown in the example above.

network block is disabled to make it easier to check network blocks
without having to reject them during configuration file parsing (which
would prevent wpa_supplicant from starting). The only additional check
added in this commit is to verify the WEP key length. Similar checks for
other parameters can be added in future commits.
