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.

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.
