Add support to use a push button -based bootstrap mechanism with DPP.
The new DPP_PUSH_BUTTON control interface command enables this mode on
the AP/hostapd and station/wpa_supplicant. This goes through the
following sequence of events: a suitable peer in active push button mode
is discovered with session overlap detection, PKEX is executed with
bootstrap key hash validation, DPP authentication and configuration
exchanges are performed.

Move most of CHANWIDTH_* definitions from ieee80211_defs.h to defs.h as
the definitions are getting used mostly for internal purpose only. Also
change prefix of the definitions to CONF_OPER_CHWIDTH_* and update in
all the files accordingly.
Leave the couple of VHT-specific exceptions to use the old defines (the
reason why they were originally added as VHT values), to avoid use of
clearly marked configuration values in information elements. In
addition, use the defines instead of magic values where appropriate.

For hidden GBK encoding of a Chinese SSID, both the UTF-8 and GBK
encoding profiles are added into wpa_supplicant to make sure the
connection succeeds. In this situation, wpa_supplicant_select_network()
will not be called so current_ssid is NULL when association begins.
Android monitors the WPA_EVENT_STATE_CHANGE event to get the SSID and
BSSID. When connecting to a Chinese SSID, in case of association
rejection happens, Android will report null SSID to OEM APP because
current_ssid is updated after wpa_supplicant_set_state(wpa_s,
WPA_ASSOCIATING), which may cause confusion.
Fix this by setting the current_ssid before changing state to

RSN design is supposed to encrypt all Data frames, including EAPOL
frames, once the TK has been configured. However, there are deployed
implementations that do not really follow this design and there are
various examples from the older uses of EAPOL frame where those frames
were not encrypted. As such, strict filtering of unencrypted EAPOL
frames might results in undesired interoperation issues.
However, some of the most important cases of missing EAPOL frame
encryption should be possible to handle without causing too significant
issues. These are for cases where an attacker could potentially cause an
existing association to be dropped when PMF is used. EAP-Request is one
potential candidate for such attacks since that frame could be used to
initiate a new EAP authentication and the AP/Authenticator might not
allow that to complete or a large number of EAP-Request frames could be
injected to exceed the maximum number of EAP frames. Such an attack
could result in the station ending up disconnecting or at minimum,
getting into somewhat mismatching state with the AP.
Drop EAPOL-EAP frames when it is known that it was not encrypted but
should have been and when PMF is enabled. While it would be correct to
drop this even without PMF, that does not provide any significant
benefit since it is trivial to force disconnection in no-PMF cases. It
should also be noted that not all drivers provide information about the
encryption status of the EAPOL frames and this change has no impact with
drivers that do not indicate whether the frame was encrypted.

Send the status code from the AP authentication response instead of
sending the hardcoded WLAN_STATUS_UNSPECIFIED_FAILURE when the external
SAE authentication failure is due to an explicit rejection by the AP.
This will allow the driver to indicate the correct status in connect
response.
For example, an AP can send WLAN_STATUS_AP_UNABLE_TO_HANDLE_NEW_STA in
SAE authentication response. With this change the driver gets the real
status for the SAE authentication failure and it can fill the correct
status in the connect response event.

The TLS protocol design for renegotiation was identified to have a
significant security flaw in 2009 and an extension to secure this design
was published in 2010 (RFC 5746). However, some old RADIUS
authentication servers without support for this are still used commonly.
This is obviously not good from the security view point, but since there
are cases where the user of a network service has no realistic means for
getting the authentication server upgraded, TLS handshake may still need
to be allowed to be able to use the network.
OpenSSL 3.0 disabled the client side workaround by default and this
resulted in issues connection to some networks with insecure
authentication servers. With OpenSSL 3.0, the client is now enforcing
security by refusing to authenticate with such servers. The pre-3.0
behavior of ignoring this issue and leaving security to the server can
now be enabled with a new phase1 parameter allow_unsafe_renegotiation=1.
This should be used only when having to connect to a network that has an
insecure authentication server that cannot be upgraded.
The old (pre-2010) TLS renegotiation mechanism might open security
vulnerabilities if the authentication server were to allow TLS
renegotiation to be initiated. While this is unlikely to cause real
issues with EAP-TLS, there might be cases where use of PEAP or TTLS with
an authentication server that does not support RFC 5746 might result in
a security vulnerability.

When a station receives either a Beacon frame or a Probe Response frame
from an AP that contains an MBO element with the Association Disallowed
attribute, the station should prevent association to that AP. When using
passive scanning, it is possible for the scan results to contain the
latest information in the Beacon frame elements instead of the Probe
Response frame elements. That could result in using old information and
not noticing the AP having changed its state to disallowing new
associations.
Make it more likely to follow the AP's change to disallow associations
by checking the Beacon frame elements instead of Probe Response frame
elements if the scan results are known to contain newer information for
the Beacon frame.
