sm->pairwise_set needs to be set whenever the TK has been configured to
the driver to request following EAPOL frames to be encrypted (or more
specifically, not to request them to not be encrypted). The FILS case
missed this setting and that could result in rekeying or
reauthentication in an associated started with FILS not working
correctly.

The wpa_supplicant check for whether a TK is configured into the driver
was broken during the time this information is needed for rekeying or
reauthenticating with another 4-way handshake. sm->ptk.installed is not
set at the point the EAPOL-Key msg 4/4 is sent and while that means the
initial 4-way handshake needs to prevent encryption, the consecutive
4-way handshake must not be doing that since the old key (TK) is still
in the driver. Fix this so that the EAPOL-Key msg 4/4 during rekeying
does not get transmitted without encryption.

Currently a corrupted handshake message 1/4 causes the client to
disconnect from the network. This can lead to a denial-of-service
vulnerability allowing an adversary to forcibly disconnect a client from
protected networks even when Wi-Fi Management Frame Protection (MFP) is
enforced if the driver allows unencrypted EAPOL-Key frames to be
received after key configuration..
Fix this by discarding the corrupted handshake message 1/4.
This issue was discovered by Domien Schepers (Northeastern University)
and Mathy Vanhoef (imec-DistriNet, KU Leuven).

wpa_validate_wpa_ie() might update sm->* values, so it should not be

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.

Add a notification message to indicate reason for TLS handshake failure
due to the server not supporting safe renegotiation (RFC 5746).
Signed-off-by: Jouni Malinen <quic_jouni@quicinc.com>
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.

TLS 1.3 sends the OCSP response with the server Certificate message.

The internal flag prot_success_received was not cleared between the
sessions and that resulted in the resumed session not mandating the
protected success indication to be received. Fix this by clearing the
internal flag so that the EAP-TLS handshake using session resumption
with TLS 1.3 takes care of the required check before marking the
authentication successfully completed. This will make the EAP-TLS peer
reject an EAP-Success message should it be received without the
protected success indication.
