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 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>
