ocsp=3 extends ocsp=2 by require all not-trusted certificates in the
server certificate chain to receive a good OCSP status. This requires
support for ocsp_multi (RFC 6961). This commit is only adding the
configuration value, but all the currently included TLS library wrappers
are rejecting this as unsupported for now.

This adds a new hostapd configuration parameter
ocsp_stapling_response_multi that can be used similarly to the existing
ocsp_stapling_response, but for the purpose of providing multiple cached

This adds support for hostapd-as-authentication-server to be build with
the internal TLS implementation and OCSP stapling server side support.
This is more or less identical to the design used with OpenSSL, i.e.,
the cached response is read from the ocsp_stapling_response=<file> and
sent as a response if the client requests it during the TLS handshake.

This error case in own buffer lengths being too short was not handled

When AES-WRAP was used to protect the EAPOL-Key Key Data field, this was
decrypted using a temporary heap buffer with aes_unwrap(). That buffer
was not explicitly cleared, so it was possible for the group keys to
remain in memory unnecessarily until the allocated area was reused.
Clean this up by clearing the temporary allocation explicitly before
freeing it.

On systems that have multiple WLAN rfkill instances, the rfkill code
can become confused into thinking that the device was unblocked when
in fact it wasn't, because it only matches on the WLAN type.
Since it then stores the new (unblocked) state from the wrong rfkill
instance, it will never retry the failing IFF_UP operation and the
user has to toggle rfkill again, or otherwise intervene manually, in
this case to get back to operational state.
Fix this by using the existing (but unused) ifname argument when the
rfkill instance is created to match to a specific rfkill index only.
As a P2P Device interface does not have a netdev interface associated
with it, use the name of a sibling interface to initialize the rfkill
context for the P2P Device interface. For nl80211, as the wiphy index
is known only after getting the driver capabilities from the kernel,
move the initialization of the rfkill object to
wpa_driver_nl80211_finish_drv_init().

The rfkill processing in nl80211 driver assumes that the
INTERFACE_ENABLED/DISABLED will be also issued, so does not do much in
the rfkill callbacks. However, as a P2P Device interface is not
associated with a network interface, these events are not issued for it.
Handle rfkill events for the P2P_DEVICE interface by faking the
INTERFACE_ENABLED/DISABLED.

This patch fixes an issue with an invalid phase2 parameter value
auth=MSCHAPv2 getting interpreted as auth=MSCHAP (v1) which could
degrade security (though, only within a protected TLS tunnel). Now when
invalid or unsupported auth= phase2 parameter combinations are
specified, EAP-TTLS initialization throws an error instead of silently
doing something.
More then one auth= phase2 type cannot be specified and also both auth= and
autheap= options cannot be specified.
Parsing phase2 type is case sensitive (as in other EAP parts), so phase2
parameter auth=MSCHAPv2 is invalid. Only auth=MSCHAPV2 is correct.

This adds support for optional functionality to validate server
certificate chain in TLS-based EAP methods in an external program.
wpa_supplicant control interface is used to indicate when such
validation is needed and what the result of the external validation is.
This external validation can extend or replace the internal validation.
When ca_cert or ca_path parameter is set, the internal validation is
used. If these parameters are omitted, only the external validation is
used. It needs to be understood that leaving those parameters out will
disable most of the validation steps done with the TLS library and that
configuration is not really recommend.
By default, the external validation is not used. It can be enabled by
addingtls_ext_cert_check=1 into the network profile phase1 parameter.
When enabled, external validation is required through the CTRL-REQ/RSP
mechanism similarly to other EAP authentication parameters through the
control interface.
The request to perform external validation is indicated by the following
event:
CTRL-REQ-EXT_CERT_CHECK-<id>:External server certificate validation needed for SSID <ssid>
Before that event, the server certificate chain is provided with the
CTRL-EVENT-EAP-PEER-CERT events that include the cert=<hexdump>
parameter. depth=# indicates which certificate is in question (0 for the
server certificate, 1 for its issues, and so on).
The result of the external validation is provided with the following
command:
CTRL-RSP-EXT_CERT_CHECK-<id>:<good|bad>
It should be noted that this is currently enabled only for OpenSSL (and
BoringSSL/LibreSSL). Due to the constraints in the library API, the
validation result from external processing cannot be reported cleanly
with TLS alert. In other words, if the external validation reject the
server certificate chain, the pending TLS handshake is terminated
without sending more messages to the server.
