c69ce778f6 Fix building against OpenSSL 3
Smartcard support uses the ENGINE API of OpenSSL, which has been
deprecated as of OpenSSL 3. Rather than migrating the code to the new API
or pretending that we do not support OpenSSL 3, accept that we use
deprecated functionality.

5589d62c57 nl80211: Avoid NL80211_WPA_VERSION_3 on older kernel versions
NL80211_WPA_VERSION_3 was only added in kernel 5.2 so it should not be
set for older kernel versions.  There is no direct way to check if the
value is supported. However, we can use the new infrastructure to check
whether the kernel has the NL80211_ATTR_SAE_PASSWORD attribute. It is
related and was added at the same time.

71bcb97b8c tests: Use pgrep instead of ps
The ps command as shipped by busybox does not support the "command"
column. Change the code to use pgrep instead which will work fine in all
environments.

In addition, raise an exception if PID was not found since the test
would just hang with pid = 0.

Now that we have a more advanced check for the differences within the
Key Data field, nonzero Key Data Length case can be determined to be

4abc37e67b Support Key Data field decryption for EAPOL-Key msg 2/4 and 4/4
Extend RSN authenticator to be able to process EAPOL-Key msg 2/4 and 4/4
messages in cases where the Key Data field is encrypted using AES key
wrapping (i.e., non-AEAD cipher). While there is not yet any defined
case where such encryption would be used in IEEE Std 802.11-2020,
extensions are considered to be added to use such constructions (e.g.,
in IEEE P802.11bh). As such, it is good to extend the parsing and
processing rules in the authenticator to be ready for such
functionality.

f7a903654f Extend mechanism to distinguish EAPOL-Key msg 2/4 from 4/4
The initial Authenticator implementation depended on the Key Data field
being empty for EAPOL-Key msg 4/4. This worked fine for years in
practice, but in theory, vendor specific elements or KDEs could have
been added inti EAPOL-Key msg 4/4 and that would have broken this
design. In addition, the MLD case did introduce a KDE into EAPOL-Key msg
4/4 and required changes here.

As an initial step to make this more robust for future extensions,
recognize a received EAPOL-Key message as msg 4/4 if it is for RSN
(i.e., not WPAv1), has Secure=1, contains an unencrypted Key Data field,
and does not include RSNE.

af6e21faa0 P2P: Fix a logical error of workaround of extended listen failure
When p2p->state == P2P_LISTEN_ONLY, the statement before it
'p2p->cfg->is_p2p_in_progress(p2p->cfg->cb_ctx)' will be true, too, so
this function will print a message "Operation in progress" and return;
the workaround to handle listen failure will be never reached.

I met such an error when the 'remain-on-channel' command failed, then
the function p2p_ext_listen_timeout() just printed 'Operation in
progress' again and again, and the listen operation was not started
anymore.

f136837202 nl80211: Pass wiphy events to all affected interfaces
Previously, we would only pass the event to the first interface that
matches. However, one wiphy can have multiple interfaces and each one
needs to get the event delivered. Without this, it could e.g. happen
that a radar detection event is forwarded to p2p-dev-wlan0 and not to
the wlan0 interface which actually needs it.

As such, keep iterating if we are processing a wiphy match and send the
event to all affected BSSs.

11.25.3 (MSCS procedures):

If an MSCS Descriptor element is present in a MSCS Response
frame that does not indicate a status of "SUCCESS", the request
type field is set to "change" - the element indicates a suggested

subsequent request by the non-AP STA.

Handle both MSCS Response frame and (Re)Association Response frame with
change request by extending WPA_EVENT_MSCS_RESULT with the change
values.

Note: since we extend MSCS_RESULT event, move the original event from
both MSCS Response frame and (Re)Association Response frame handlers to
a common function that handles now both 'change' and other response.
