The previous implementation did not check that we are associated with
the sender of the GAS response before checking for PMF status. This
could have accepted Venue URL when not in associated state. Fix this by
explicitly checking for association with the responder first.
This fixes an issue that was detected, e.g., with these hwsim test case

Force use of the wildcard BSSID address in GAS query frames with DPP
regardless of how the gas_address3 configuration parameter is set. DPP
specification mandates this and the use of GAS here is really outside
the context of a BSS, so using the wildcard BSSID makes sense even for
the corner case of Configurator running on a known AP (where IEEE 802.11
standard would allow the BSSID of the AP to be used).

If the configured credential includes a username without '@' (i.e., no

This adds a new command based Hotspot 2.0 icon retrieval option.
In short, here is the new command sequence:
1. REQ_HS20_ICON <bssid> <file-name>
2. event: RX-HS20-ICON <bssid> <file-name> <size>
3. GET_HS20_ICON <bssid> <file-name> <offset> <size>
(if needed, repeat with larger offset values until full icon is
fetched)
5. DEL_HS20_ICON <bssid> <file-name>
REQ_HS20_ICON is a new command that is analogous to HS20_ICON_REQUEST
with the slight difference that an entry to store the icon in memory is
prepared. The RX-HS20-ICON event has been augmented with BSSID,
file-name and size, and GET_HS20_ICON is used to retrieve a chunk of up
to <size> bytes of icon data at offset <offset>. Each chunk is returned
as a base64 encoded fragment, preceded by "HS20-ICON-DATA", BSSID, and
file-name as well as the starting offset of the data.
If there is no entry prepared for the icon when the ANQP result comes
back, hs20_process_icon_binary_file falls back to legacy behavior.
Finally the DEL_HS20_ICON command deletes (all) icons associated with
BSSID and file-name (there could be several if retries are used and they
have different dialog tokens).

"anqp[265]=<hexdump>".

While being associated, if an ANQP request is received for a different
AP that doesn't exist in the BSS list, the ANQP request will be sent on
the frequency of the AP that we are currently associated to.
In such a case, it is possible that the ANQP request would be sent on
a channel different than that of the requested AP, potentially delaying
other requests/activities.
Avoid sending the ANQP request to an AP that is not in the BSS list.

interworking_credentials_available_3gpp() would have left excluded2
uninitialized without INTERWORKING_3GPP in the build. This could result
in a static analyzer warning within
interworking_credentials_available_helper() about use of uninitialized
variable. Get rid of that warning by explicitly initializing excluded2
even though this does not really result in any difference in behavior
since the excluded2 value would be used only if the non-NULL is returned
and that could not have been the case here without INTERWORKING_3GPP.

This can be used to provide more control to upper layers on network
blocks generated as part of Interworking network selection.
INTERWORKING_ADD_NETWORK behaves otherwise identically to
INTERWORKING_CONNECT, but it does not request a new connection after
having added the network block and it returns the network id of the
added network.
INTERWORKING_ADD_NETWORK followed by REASSOCIATE would behave more or
less identically to INTERWORKING_CONNECT, but this allows the created
network profile to be modified, if desired, and/or stored externally.
SELECT_NETWORK can also be used with the network id returned from
INTERWORKING_ADD_NETWORK to enforce that specific network profile to be
used for the next connection (though, it should be noted that this
behavior may not meet all Hotspot 2.0 requirements if there were other
enabled networks that could have higher priority).

other reason of duplicated BSS entries was present while doing ANQP

It was possible for interworking_find_network_match() to find a possible
BSS match in a case where more thorough checks in
wpa_supplicant_select_bss() reject network. This itself is fine, in
general, but when combined with wpa_supplicant_fast_associate()
optimization and auto_interworking=1, this resulted in a busy loop of up
to five seconds and a possible stack overflow due to recursion in that
loop.
Fix this by limiting the Interworking wpa_supplicant_fast_associate()
call to be used only once per scan iteration, so that new scan
operations can be completed before going through the scan results again.

Reduce maximum stack use by starting next ANQP fetch operation from an

ANQP operations are executed in cases where automatic Interworking
network selection is used and scan results do not have a full match for

For one specific case when running with Interworking enabled the
re-initialisation of the scan timer is missing. This makes auto connect
to a configured network fail.
The case is:
- Interworking credentials available, but do not match
- Auto interworking is enabled (auto_interworking=1)
- Interworking auto select is disabled (i.e., this is from
auto_interworking=1, not from INTERWORKING_SELECT auto)
- No configured (enabled and non blacklisted) networks are present
in scan results list with full match
- Interworking finds matching networks (it does not do full security
policy match)
This patch covers the case and re-initialises the scan timer to allow
search for a suitable network to continue.
