Interworking: Add ANQP query requests Add mechanism for using GAS/ANQP to query Interworking related information from APs. The received information is stored in the BSS table and can be viewed with ctrl_iface BSS command. New ctrl_iface command ANQP_GET can be used to fetch ANQP elements from a specific AP. Additional commands FETCH_ANQP and STOP_FETCH_ANQP can be used to initiate and stop an iteration through all APs in the BSS table that indicate support Interworking to fetch ANQP elements from them.

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. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

Interworking: Keep up to two pending GAS_REQUEST responses Previously, only the last response data was kept in memory. This increases that to hold up to two last responses to allow some more parallel operations to be requested. In addition, the response data is now freed as soon as the external program has fetched it. Signed-hostap: Jouni Malinen <j@w1.fi>

Interworking: Continue ANQP fetch after TX failure If the driver rejected any of the offchannel Action frame TX requests, the previous implementation terminated ANQP fetch process. While the driver should not really reject the request normally, it is possible that a request gets rejected for some reason. Allow the fetch process to continue with the next AP in such case to avoid breaking networking selection. This could result, e.g., in auto_interworking=1 process failing to connect if any the driver rejects requests to any of the APs in the scan result even if some other APs provided suitable information.

Add INTERWORKING_ADD_NETWORK command This can be used to provide more control to upper layers on network blocks generated as part of Interworking network selection.

In addition, this is easier to support in case there is a large number of realms that can be used for authentication. Signed-hostap: Jouni Malinen <j@w1.fi>

Add INTERWORKING_ADD_NETWORK command 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).

In addition, this is easier to support in case there is a large number of realms that can be used for authentication. Signed-hostap: Jouni Malinen <j@w1.fi>

Add INTERWORKING_ADD_NETWORK command 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).

For example, "ANQP_GET <BSSID> 265" can be used to fetch the AP Geospatial Location ANQP-element and if the AP has this information, the "BSS <BSSID>" command will include the response as "anqp[265]=<hexdump>".

Interworking: Try to use same BSS entry for storing GAS results There may be cases where multiple BSS entries for a single BSSID are in the table. This is mostly in automated test cases due to the AP configuration changes, but something similar could potentially happen as a corner case in more realistic networks, too, e.g., when an AP changes its operating channel. Make network selection more robust by trying to find the exact BSS entry instead of any BSS entry with a matching BSSID when storing GAS/ANQP response. Signed-hostap: Jouni Malinen <j@w1.fi>

HS 2.0: Add a command to retrieve icon with in-memory storage 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).

HS 2.0: Try to use same BSS entry for storing GAS results Commit 17b8995cf5813d7c027cd7a6884700e791d72392 ('Interworking: Try to use same BSS entry for storing GAS results') added a mechanism to try to pair GAS request and response to a single BSS entry to cover cases where multiple BSS entries may exists for the same BSSID. However, that commit did not cover the Hotspot 2.0 ANQP elements. Extend this mechanism to all ANQP elements. This can help in cases where information in the Hotspot 2.0 specific ANQP elements got lost if a hidden SSID or some other reason of duplicated BSS entries was present while doing ANQP fetches.

HS 2.0: Add a command to retrieve icon with in-memory storage 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).

Additional commands FETCH_ANQP and STOP_FETCH_ANQP can be used to initiate and stop an iteration through all APs in the BSS table that indicate support Interworking to fetch ANQP elements from them.

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 070108010c01dddd0c00 > 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. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

GAS: Delay GAS query Tx while another query is in progress It would be possible to issue another GAS query when a previous one is still in progress and this could result in conflicting offchannel operations. Prevent that by delaying GAS query initiation until the previous operation has been completed. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
