476aed355a Interworking: Move BSS ANQP information into separate struct
This is an initial step in allowing the ANQP responses to be shared

59ff6653aa Fix REMOVE_NETWORK to not run operations with invalid current_ssid
If the REMOVE_NETWORK command is used to delete the currently connected
network, some operations were run between removing the network and
clearing of wpa_s->current_ssid. This left wpa_s->current_ssid pointing
to freed memory and should any operation end up using it before the
pointer gets cleared, freed memory could be references. Avoid this by
removing the network only after having completed the operations that
clear wpa_s->current_ssid.

eb7719ff22 Add support for using GCMP cipher from IEEE 802.11ad
This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.

This commit does not included changes to WPS or P2P to allow GCMP to be
used.

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
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.

Do not try to associate with a network that has an invalid or incomplete
configuration because the association or at least data connection would

network block is disabled to make it easier to check network blocks

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.
