While other authentication algorithms mark Status Code as being Reserved
in the case of the transaction number 1, SAE does not. Check that the
Status Code indicates success before creating SAE state. In addition,
fix the mesh anti-clogging token request parsing on big endian CPUs.
Transaction number 2 (confirm) can also have non-zero Status Code to
report an error. Those should be processed, but not replied to with yet
another error message. This could happen in mesh case. Avoid a loop of
error messages by dropping the non-success case without additional
response.
In addition, don't reply to unknown transaction numbers if the status
code is non-zero. This avoids a loop of error messages if an invalid
frame where to be injected (or unlikely corruption were to occur).

Commit d4913c585e ('OpenSSL: Fix EAP-FAST
peer regression') introduced a workaround to use a new SSL_CTX instance
set for TLSv1_method() when using EAP-FAST. While that works, it is
unnecessarily complex since there is not really a need to use a separate
SSL_CTX to be able to do that. Instead, simply use SSL_set_ssl_method()
to update the ssl_method for the SSL instance. In practice, this commit
reverts most of the tls_openssl.c changes from that earlier commit and
adds that single call into tls_connection_set_params() based on EAP-FAST
flag.

Commit 35efa2479f ('OpenSSL: Allow TLS
v1.1 and v1.2 to be negotiated by default') changed from using
TLSv1_method() to SSLv23_method() to allow negotiation of TLS v1.0,
v1.1, and v1.2.
Unfortunately, it looks like EAP-FAST does not work with this due to
OpenSSL not allowing ClientHello extensions to be configured with
SSL_set_session_ticket_ext() when SSLv23_method() is used. Work around
this regression by initiating a separate SSL_CTX instance for EAP-FAST
phase 1 needs with TLSv1_method() while leaving all other EAP cases
using TLS to work with the new default that allows v1.1 and v1.2 to be
negotiated. This is not ideal and will hopefully get fixed in the future
with a new OpenSSL method, but until that time, this can be used allow
other methods use newer TLS versions while still allowing EAP-FAST to be
used even if it remains to be constraint to TLS v1.0 only.

Commit ac330cfd87 ('P2P: Reinvite with
social operation channel if no common channels') introduced a mechamisn
to reinvite a peer during a persistent group reinvocation from a GO with
a different operating channel proposal. This mechanism can fail if the
inviting device (GO) ends up getting a retransmitted, duplicated
Invitation Response frame processed second time while waiting for the
response to the retried Invitation Request (using one of the social
channels as the operating channel). IEEE 802.11 duplicate frame
detection mechanisms are supposed to prevent this type of sequence, but
not all drivers support those rules properly for pre-association frames,
including P2P Public Action frames.
Work around this issue by checking that the dialog token in the
Invitation Response frame matches the one from the last Invitation
Request if the special invitation retry mechanism is used. This is safer
to do now than to enable dialog token matching for all invitation cases.

It is possible for unmasking of 11b rates to fail if a P2P group is
terminated while the netdev is down (e.g., due to rfkill block). This
could result in the 11b TX rates being left masked for non-P2P
operations. This would be particularly unfortunate for channel 14 use
since OFDM rates are not allowed on channel 14 and only OFDM rates were
configured P2P. This issue showed up, e.g., when running hwsim test case
rfkill_autogo followed by ap_wps_conf_chan14.
It may be possible to allow the failed operation in cfg80211/mac80211,
but it looks better to work around this on wpa_supplicant side as well.
Try to unmask the 11b rates again on the next connection request if the
rate unmasking operation had failed.
