4537fe124a P2P: Explicit nul termination of the generated passphrase
Nul terminate the struct p2p_go_neg_results::passphrase explicitly to
keep static analyzers happier. This was already nul terminated in
practice due to the full array being cleared to zero on initialization,
but that was apparently not clear enough for some analyzers.

8690374439 Discard unencrypted EAPOL/EAP when TK is set and PMF is enabled (AP)
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. EAPOL-Start and
EAPOL-Logoff are potential candidate for such attacks since those frames
could be used to terminate an authentication or initiate a new EAP
authentication. Such an attack could result in the station ending up
disconnecting or at minimum, getting into somewhat mismatching state
with the AP.

Drop EAPOL-Start/Logoff/EAP frames on the AP/Authenticator 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.

sm->pairwise_set needs to be set whenever the TK has been configured to

specifically, not to request them to not be encrypted). The FILS case

98278c0de0 Fix no_encrypt flag in control port TX for rekeying
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.

b1172c19e1 WPA: Discard EAPOL-Key msg 1/4 with corrupted information elements
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.

and Mathy Vanhoef (imec-DistriNet, KU Leuven).

566ce69a8d EAP peer: Workaround for servers that do not support safe TLS renegotiation
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.

With the latest Linux kernel (5.12 version onward), interface
creation/deletion is not allowed using vendor commands as it leads to a
deadlock while acquiring the RTNL_LOCK during the register/unregister of
netdev. Create and delete NDP interface using NL80211_CMD_NEW_INTERFACE

Copy channels from only valid operating classes in the source channel
list while preparing a non-6 GHz channel/op-classes list when the 6 GHz
band is not used for P2P GO negotiation.

Earlier, during preparation of P2P channels for GO negotiation, a union
of the GO channels and the P2P Client channels is used. While generating
the union in p2p_channels_union_inplace() as the first list itself has
P2P_MAX_REG_CLASSES number of entries, the operating classes from the
second list which are not in the first list were not getting considered.

Fix this by not setting the dst->reg_classes to too large a value.
