This is a generic AES GCM and GMAC implementation that can be used for
other purposes than just implementing GCMP, so it fits better in a
separate file in src/crypto.

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.

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.

This driver_op can now be used in station mode, too, to fetch

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.

When building the Invitation Request for WFD use cases, match the BSSID,
i.e., P2P Interface Address, of the group on the GO to avoid using
information from another group should the device be operating multiple
concurrent groups as GO.

Store permanent username (i.e., including prefix character) instead of
IMSI in the SQLite DB. Convert the string to a string since the EAP-AKA
prefix can start with zero. This cleans up the field names since the
value was already with the prefix included instead of just IMSI. In
addition, this explicitly removes some theoretical cases where the
different identity types could have been mixed.
Signed-hostap: Jouni Malinen <j@w1.fi>
Since the EAP-SIM/AKA identities are ASCII strings, there is no need to
use more complex way for storing and passing them. In addition, be more
strict about enforcing username (i.e., no realm part) to be used in the
EAP-SIM DB API. Similarly, require specific username type instead of any
of the types to be used as the key in the pseudonym and reauth
operations. This allows simpler lookup operations to be used.

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.
