Commit f1df4fbfc7 ("mesh: Use setup completion callback to complete
mesh join") added a check for iface->conf being NULL into a debug print.
However, it is not clear how that could be NULL here. In any case,
setup_interface() could end up dereferencing iface->conf in the call to
hostapd_validate_bssid_configuration(), so better be consistent with the
checks and not get warnings from static analyzers regardless of whether
this can happen in practice.

These frames are used for verifying that a specific SA and protected
link is in functional state between two devices. The IEEE 802.11
standard defines only a case that uses individual MAC address as the
destination. While there is no explicit rule on the receiver to ignore
other cases, it seems safer to make sure group-addressed frames do not
end up resulting in undesired behavior. As such, drop such frames
instead of interpreting them as valid SA Query Request/Response.

For an autonomous P2P group on the 5 GHz band, a channel was picked only
from the operating class 115 which is not available in the EU region
anymore. As a result, an autonomous group creation would always fail in
this generic 5 GHz channel case.
There are more possible available channels for the 5 GHz currently.
Especially in the EU region, the operating class 115 channels are no
longer available, but SRD channels (the operating class 124) are
available. Allow them to be used here if they are marked as allowed for
P2P GO use.
In addition, iterate through all the potential options instead of just
checking the first randomly picked channel. Start this iteration from
random position to maintain some randomness in this process.

p2p_add_device() may remove the oldest entry if there is no room in the
peer table for a new peer. This would result in any pointer to that
removed entry becoming stale. A corner case with an invalid PD Request
frame could result in such a case ending up using (read+write) freed

maximum size and the PD Request frame is received from the P2P Device
Address of the oldest remaining entry and the frame has incorrect P2P
Device Address in the payload.
Fix this by fetching the dev pointer again after having called
p2p_add_device() so that the stale pointer cannot be used.

Reordering of code in handle_auth_cb() when adding support for full
station state messaged up frame length checks. The length was originally
tested before looking at the payload of the frame and that is obviously
the correct location for that check. The location after those full state
state changes was after having read six octets of the payload which did
not help at all since there was no addition accesses to the payload
after that check.
Move the payload length check to appropriate place to get this extra
level of protection behaving in the expected manner. Since this is a TX
status callback handler, the frame payload is from a locally generated
Authentication frame and as such, it will be long enough to include
these fields in production use cases. Anyway, better keep this check in
working condition.

EAP peer does not expect data present when beginning the Phase 2 in
EAP-{TTLS,PEAP} but in TLS 1.3 session tickets are sent after the
handshake completes.
There are several strategies that can be used to handle this, but this
patch picks up from the discussion[1] and implements the proposed use of
SSL_MODE_AUTO_RETRY. SSL_MODE_AUTO_RETRY has already been enabled by
default in OpenSSL 1.1.1, but it needs to be enabled for older versions.
The main OpenSSL wrapper change in tls_connection_decrypt() takes care
of the new possible case with SSL_MODE_AUTO_RETRY for
SSL_ERROR_WANT_READ to indicate that a non-application_data was
processed. That is not really an error case with TLS 1.3, so allow it to
complete and return an empty decrypted application data buffer.
EAP-PEAP/TTLS processing can then use this to move ahead with starting
Phase 2.

The RADIUS client currently determines if a radius message is longer
than the supported maximum length by checking whether the size of the
received buffer and the length of the buffer (as returned by recv()) is
equal. This method fails to detect if the buffer has actually been
truncated. This change modifies the RADIUS client to instead use the

whether or not the received message has been truncated and drop the

RADIUS_MAX_MSG_LEN within the header file radius.h and modifies
