When a station receives either a Beacon frame or a Probe Response frame
from an AP that contains an MBO element with the Association Disallowed
attribute, the station should prevent association to that AP. When using
passive scanning, it is possible for the scan results to contain the
latest information in the Beacon frame elements instead of the Probe
Response frame elements. That could result in using old information and
not noticing the AP having changed its state to disallowing new
associations.

by checking the Beacon frame elements instead of Probe Response frame
elements if the scan results are known to contain newer information for

After receiving a BSS Transition Management request,
wpa_supplicant_connect() will abort ongoing scans, which will cause scan
results to be reported. Since the reassociate bit is set, this will
trigger a connection attempt based on the aborted scan's scan results

wpa_supplicant to reassociate to the same AP it is currently associated
to instead of the AP it was asked to transition to.

wpa_supplicant generates both a PMKSA cache entry and ERP keys upon
successful FILS connection and uses FILS authentication algorithm for
subsequent connections when either ERP keys or a PMKSA cache entry is
available.
In some cases, like AP/RADIUS server restart, both ERP keys and PMKSA
becomes invalid. But currently when an AP rejects an association,
wpa_supplicant marks only ERP keys as failed but not clearing PMKSA.
Since PMKSA is not cleared, consecutive connection attempts are still
happening with FILS authentication algorithm and connection attempts are
failing with the same association rejection again instead of trying to
recover from the state mismatch by deriving a new ERP key hierarchy.
Clear PMKSA entries as well on association rejection from an AP to allow
the following connection attempt to go with open authentication to
re-establish a valid ERP key hierarchy. Also, since clearing PMKSA
entries on unprotected (Re)Association Response frames could allow DoS
attack (reduce usability of PMKSA caching), clear PMKSA entries only
when ERP keys exists.

- PASN with FT key derivation requires knowledge of the PMK-R1 and

etc. only for the currently associated AP, store the mapping of
BSSID to R1KH-ID for each previous association, so the R1KH-ID

of storing the PMK-R1 to avoid maintaining keys that might not

Within wpas_connection_failed(), the 'count' value of wpa_blacklist is
erroneously used as a tally of the number times the device has failed
to associate to a given BSSID without making a successful connection.
This is not accurate because there are a variety of ways a BSS can be
added to the blacklist beyond failed association such as interference
or deauthentication. This 'count' is lost whenever the blacklist is
cleared, so the wpa_supplicant stores an additional value
'extra_blacklist_count' which helps persist the 'count' through clears.
These count values are used to determine how long to wait to rescan
after a failed connection attempt.
While this logic was already slightly wrong, it would have been
completely broken by the upcoming change which adds time-based
blacklisting functionality. With the upcoming change, 'count' values
are not cleared on association, and thus do not necessarily even
approximate the "consecutive connection failures" which they were being
used for.
This change seeks to remove this unnecessary overloading of the
blacklist 'count' by directly tracking consecutive connection failures
within the wpa_supplicant struct, independent of the blacklist. This new
'consecutive_conn_failures' is iterated with every connection failure
and cleared when any successful connection is made. This change also
removes the now unused 'extra_blacklist_count' value.

The previous implementation was assuming a fixed 20 MHz channel
bandwidth when determining which operating class value to indicate as
the Current Operating Class in the Supported Operating Classes element.
This is not accurate for many HT/VHT cases.
Fix this by determining the current operating class (i.e., the operating
class used for the requested association) based on the HT/VHT operation
elements from scan results.

Specific BSSID scan was replacing wildcard SSID with the known SSID if
any BSS with the specified BSSID is available in the known BSSes list.
Add control interface support to force use of a wildcard SSID in a
specific BSSID scan by user with the new "wildcard_ssid=1" argument to
the SCAN command.

Rekeying a pairwise key using only keyid 0 (PTK0 rekey) has many broken
implementations and should be avoided when using or interacting with
one. The effects can be triggered by either end of the connection and
range from hardly noticeable disconnects over long connection freezes up
to leaking clear text MPDUs.
To allow affected users to mitigate the issues, add a new configuration
option "wpa_deny_ptk0_rekey" to replace all PTK0 rekeys with fast
reconnects.

SM Power Save was described in somewhat unclear manner in IEEE Std
802.11n-2009 as far the use of it locally in an AP to save power. That
was clarified in IEEE Std 802.11-2016 to allow only a non-AP STA to use
SMPS while the AP is required to support an associated STA doing so. The
AP itself cannot use SMPS locally and the HT Capability advertisement
for this is not appropriate.
Remove the parts of SMPS support that involve the AP using it locally.
In practice, this reverts the following commits:
04ee647d58 ("HT: Let the driver advertise its supported SMPS modes for AP mode")
8f461b50cf ("HT: Pass the smps_mode in AP parameters")
da1080d721 ("nl80211: Advertise and configure SMPS modes")

The 5 GHz channels are stored in one hw_features set with mode
HOSTAPD_MODE_IEEE80211A while the 6 GHz channels will need to be stored
in a separate hw_features set (but with same mode
HOSTAPD_MODE_IEEE80211A) due to possibility of different HT/VHT/HE
capabilities being available between the 5 GHz and 6 GHz bands.
Iterate through all hw_features sets and check and match the band of
channel supported by the hw_features set while getting the hw_features
set in get_mode(). This allows both the 5 GHz and 6 GHz channels to be
found and correct capabilities to be used in cases where the driver
reports different capability values between 5 and 6 GHz channels.

This variable is not specific to any P2P group interface and since it
was already used through global->p2p_init_wpa_s, it is cleaner to simply
move this to the global structure so that there is a single variable
instead of per-interface variables and need to pick the correct
interface.

"SET driver_signal_override <BSSID> [<si_signal< <si_avg_signal>
<si_avg_beacon_signal> <si_noise> <scan_level>]" command can now be used
to request wpa_supplicant to override driver reported signal levels for
signal_poll and scan results. This can be used to test roaming behavior.

This is targeting the case of MAC address change for an association
which may require the interface to be set down for a short moment.
Previously, this ended up flushing the BSS table that wpa_supplicant
maintained and that resulted in having to scan again if the MAC address
was changed between the previous scan and the connection attempt. This
is unnecessary extra latency, so maintain the BSS entries for 5 seconds
(i.e., the same time that the old scan results are consider valid for a
new connection attempt) after an interface goes down.

This allows a P2P connection over P802.11ay EDMG channels to achieve the
highest link speed that the standard allows for channel bonding (CB) up
to CB4.
Let each P2P peer add its EDMG channels to the Supported Channels IE
advertised in P2P GO negotiation. Give EDMG channels priority when peers
negotiate for operating channel.
User may add 'edmg' parameter to p2p_connect, p2p_add_group, and
p2p_invite commands to prefer an EDMG channel for the P2P link. User may
also set p2p_go_edmg=1 in wpa_supplicant configuration file to prefer
EDMG.
When EDMG is used, P2P will try to find the highest channel bonding
supported channel that matches the frequency parameter, if the devices
do not support EDMG, the P2P connection will use a legacy (1-6) 60 GHz
channel.

"SET ignore_sae_h2e_only 1" can now be used to configurate
wpa_supplicant to a test mode where it ignores AP's H2E-required

This is used only for testing AP behavior with unexpected STA behavior.
