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.

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.

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.
