Jouni Malinen 953d25ca5f HS 2.0: Fix sp_type check in ctrl_iface status command
Commit e99b4f3a14 added functionality to
check whether the current association is with the home SP. This commit
did not take into account that the domain name ANQP information could be
NULL and that could result to a NULL pointer dereference. Fix that by
validation that domain_names != NULL before calling
domain_name_list_contains().

Jouni Malinen 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.

Jouni Malinen 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

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.

not really that likely for APs supporting Interworking, it is good to
get the PSK option removed to avoid any issues with missing
