4bf3910574 Move AES-CCM implementation into src/crypto
This is a generic AES CCM implementation that can be used for other
purposes than just implementing CCMP, so it fits better in a separate
file in src/crypto.

071c6164ab Enable 256-bit key AES in internal TLS implementation
Now that the internal AES implementation supports 256-bit keys, enable
use of the TLS cipher suites that use AES-256 regardless of which crypto
implementation is used.

802bc4211b Fix AES block size handling for internal cipher
AES uses the same 128-bit block size with 128, 192, 256 bit keys, so use
the fixed block size definition instead of trying to dynamically set the
block size based on key length. This fixes use of 192-bit and 256-bit
AES keys with crypto_cipher_*() API when using the internal AES
implementation.

4425645113 AP: Configure basic rates from iface and not conf
The conf doesn't contain any basic rates in some cases. Most notably,
when starting a P2P GO in 5 GHz. Use the iface rates which are
initialized in hostapd_prepare_rates() to the conf rates or set to
default values if no conf values exist. This fixes a bug introduced in
commit e5693c4775.

f0898e9519 Make copies basic_rates list more useful
Commit e5693c4775 added a copy of the
determined basic rate set into struct hostapd_iface, but did not
actually copy the terminating -1 value. This could be problematic if
something were to actually try to use this list since would be no way to
know what is the last entry in the list. Fix this by copying the
terminating value.

a05126d620 WFD: Properly match group for WFD element in Invitation Response
The group matching should be done by comparing the P2P Interface Address
(which the group_bssid here is) to the group's BSSID and not the group
ID (which uses P2P Device Address and would have also needed the SSID).
Though, it should be noted that this case cannot really happen since a
GO in an active group would never be invited to join another group in
its GO role (i.e., if it receives an Invitation Request, it will reply
in P2P Device role). As such, this fix does not really change any
observable behavior, but anyway, it is good to keep the implementation
here consistent with the Invitation Request case.

strict about enforcing username (i.e., no realm part) to be used in the

of the types to be used as the key in the pseudonym and reauth
operations. This allows simpler lookup operations to be used.

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

The new gas_request and gas_response_get commands can be used to request

with other (including vendor specific) advertisement protocols.

gas_request <BSSID> <AdvProtoID> [Query]

> 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.
