73f06af143 wpa_supplicant: Do not invalidate PMKSA cache for bssid_* updates
These updates do not cause the PMKSA cache to become invalid. As such,
allow setting any of bssid_hint, bssid_ignore, and bssid_accept without
clearing the cache and causing the current connection to be dropped
immediately.

05c167eb0a MLD: Fail connection if ML Authentication frame could not be parsed
If the Authentication frame response did not contain the expected ML
element (or it was invalid), we cannot continue with the ML association.
As such, the only choice we have in this case is to abort the
association.

If we do continue, we would end up sending the Association Request frame
with our MLD MAC address.

f9b3ecb0ad DPP: Work arouind missing Auth Confirm ACK for testing
The dpp_test DPP_TEST_STOP_AT_AUTH_CONF case is supposed to prevent the
GAS exchange from happening. It was possible to bypass that testing
functionality if the TX status event for the Authentication Confirm
message was lost or delayed long enough for the GAS Request to be
proessed first. This could happen at least with UML time travel.

Work around this by checking for the special dpp_test case within GAS
request handling.

b427683bf0 MSCS: Extend MSCS response handling
Align MSCS response handling as described in IEEE P802.11-REVme/D4.0,
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
set of parameters that could be accepted by the AP in response to a
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.

0120d052d7 nl80211: Add NL80211_ATTR_MLO_LINK_ID for NL80211_CMD_REMAIN_ON_CHANNEL
cfg80211 requires the link ID to be specified for requests to start a
remain-on-channel operation during an ML association. This feels wrong
since the ROC operation is in most cases unrelated to the
association. However, that requirement has been in place since kernel
commit 7b0a0e3c3a88 ("wifi: cfg80211: do some rework towards MLO link
APIs") from April 2022, and as such, it looks necessary to have
wpa_supplicant work around this by specifying the currently used link ID
that would seem to match the ROC channel most closely.
