ce267f4da9 P2P: DFS offload for the autonomous GO
Enhance the P2P_GROUP_ADD command to support DFS channel with 80 and 160
MHz bandwidth to be used for autonomous GO when using offloaded DFS.

For example, 'P2P_GROUP_ADD freq=5500 max_oper_chwidth=80 ht40 vht'

- Previous behavior: AP fallback to channel 100 using 20 MHz with
  "No VHT higher bandwidth support for the selected channel 100"
- Enhanced behavior: AP starts on channel 100 using 80 MHz with
  "VHT center channel 106 for 80 or 80+80 MHz bandwidth"

This functionality is on top of the driver's capability to offload DFS,
which is advertized through WPA_DRIVER_FLAGS_DFS_OFFLOAD.

80bcd7ecd1 FILS: Flush PMKSA entries on FILS connection failure
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.

5ac977758d Reject authentication start during explicit roam requests
The roam D-Bus and ROAM control itnerface commands flip the reassociate
bit before calling wpa_supplicant_connect(). wpa_supplicant connect
eventually aborts ongoing scans (if any), which causes 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 and cancel
the initial connetion request. This often causes wpa_supplicant to
reassociate to the same AP it is currently associated to instead of the
explicitly requested roaming target.

Add a roam_in_progress flag to indicate that we're currently attempting
to roam via an explicitly request to a specific BSS so that we don't
initiate another connection attempt based on the possibly received scan
results from a scan that was in progress at the time the roam command
was received.

11355a122d Reset external_scan_running on interface deletion
Currently, the external_scan_running flag is not reset when an interface
is removed. Thus, if a connection attempt is made on another iface, it
will fail due to wpa_supplicant incorrectly assuming the radio is still
busy due to the ongoing scan.

To fix this, convert external_scan_running to a pointer to the interface
that started the scan. If this interface is removed, also reset the
pointer to NULL so that other operations may continue on this radio.

Test:
  1. Start scan on wlan0
  2. Remove wlan0
  3. Can connect to a network on wlan1

5c65ad6c0b PASN: Support PASN with FT key derivation
Add support for PASN authentication with FT key derivation:

- As IEEE P802.11az/D2.6 states that wrapped data is optional and
  is only needed for further validation of the FT security parameters,
  do not include them in the first PASN frame.

- PASN with FT key derivation requires knowledge of the PMK-R1 and
  PMK-R1-Name for the target AP. As the WPA state machine stores PMK-R1,
  etc. only for the currently associated AP, store the mapping of
  BSSID to R1KH-ID for each previous association, so the R1KH-ID
  could be used to derive PMK-R1 and PMK-R1-Name. Do so instead
  of storing the PMK-R1 to avoid maintaining keys that might not
  be used.

2fd35d9857 wpa_supplicant: Track consecutive connection failures
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.

(dpp_pfs=0) remains same as it was previously, i.e., try to use PFS if

This is also working around an interoperability issue of DPP R2 STA with
certain hostapd builds that included both OWE and DPP functionality.
That issue was introduced by commit 09368515d1 ("OWE: Process
Diffie-Hellman Parameter element in AP mode") and removed by commit
16a4e931f0 ("OWE: Allow Diffie-Hellman Parameter element to be
included with DPP"). hostapd builds between those two commits would
reject DPP association attempt with PFS. The new wpa_supplicant default
(dpp_pfs=0) behavior is to automatically try to connect again with PFS
disabled if that happens.

The previous implementation was assuming a fixed 20 MHz channel
bandwidth when determining which operating class value to indicate as

This is not accurate for many HT/VHT cases.

Fix this by determining the current operating class (i.e., the operating

1f90a49d02 STA: Allow PTK rekeying without Ext KeyID to be disabled as a workaround
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

466e48dcd7 HT: Remove SMPS in AP mode
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")

d0e116f61f Enhance get_mode() to return correct hw_mode with 6 GHz support
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.

Previously, this ended up flushing the BSS table that wpa_supplicant

was changed between the previous scan and the connection attempt. This
is unnecessary extra latency, so maintain the BSS entries for 5 seconds

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

2e06cef80a MBO/OCE: Work around misbehaving MBO/OCE APs that use RSN without PMF
The MBO and OCE specification require the station to mandate use of PMF
when connecting to an MBO/OCE AP that uses WPA2. The earlier
implementation prevented such misbehaving APs from being selected for
connection completely. This looks like the safest approach to take, but
unfortunately, there are deployed APs that are not compliant with the
MBO/OCE requirements and this strict interpretation of the station
requirements results in interoperability issues by preventing the
association completely.

Relax the approach by allowing noncompliant MBO/OCE APs to be selected
for RSN connection without PMF to avoid the main impact of this
interoperability issue. However, disable MBO/OCE functionality when PMF
cannot be negotiated to try to be as compliant as practical with the
MBO/OCE tech spec requirements (i.e., stop being an MBO/OCE STA for the
duration of such workaround association). Also disable support for BTM
in this workaround state since MBO would expect all BTM frames to be
protected.

Add support for negotiating WNM Collocated Interference Reporting. This

interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.

For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".

For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".

af835d75b7 FILS: Fix FILS connect failures after ERP key invalidation

reason, FILS authentication attempts with ERP fails and the previous
wpa_supplicant implementation ended up trying to use the same keys for
all consecutive attempts as well. This did not allow recovery from state
mismatch between the ERP server and peer using full EAP authentication.

Address this by trying to use full (non-FILS) authentication when trying
to connect to an AP using the same ERP realm with FILS-enabled network
profile if the previous authentication attempt had failed. This allows
new ERP keys to be established and FILS authentication to be used again

command, in such a case the 10 second timeout is too small and
wpa_supplicant need to wait for CAC completion or CAC timeout (up to 10
minutes).

Without such timeout modification wpa_supplicant will be unable to
connect to an AP on DFS channel, since the default authentication
timeout (10 s) is smaller than the minimum CAC time (60 s).

Tested with nl80211 DFS offload implementation.

6a252ece24 DPP: Fix GAS query removal race condition on DPP_STOP_LISTEN
If a DPP_STOP_LISTEN call happens to be received when there is a pending
gas-query radio work that has not yet been started, it was possible for
gas_query_stop() to go through gas_query_done() processing with
gas->work == NULL and that ended up with the pending GAS query getting
freed without removing the pending radio work that hold a reference to
the now freed memory. Fix this by removing the pending non-started radio
work for the GAS query in this specific corner case.

These commnds are mesh version of PMKSA_GET/ADD commands. So the usage
and security risk is similar to them. Refer to
commit 3459381dd2 ('External persistent

The MESH_PMKSA_GET command requires peer MAC address or "any" as an
argument and outputs appropriate stored PMKSA cache. And the
MESH_PMKSA_ADD command receives an output of MESH_PMKSA_GET and re-store
the PMKSA cache into wpa_supplicant. By using re-stored PMKSA cache,
wpa_supplicant can skip commit message creation which can use

bf88401d23 Add support to abort vendor scan
This commit enhances the existing implementation of abort scan to also
abort concurrent active vendor scans. This is achieved by passing the
the scan_cookie to the driver interface with the intention to abort
the specific scan request. This scan_cookie is returned from the driver
interface when the scan request is scheduled.

This scan_cookie is 0 if the scan is triggered through the upstream
cfg80211 interface. Thus, the scan_cookie is used to determine whether
to abort the cfg80211 or vendor scan request.

Also, the previous implementation of relying on scan_work/p2p_scan_work
for the active work to trigger the abort scan is enhanced to check for
the started state of either of these work operations. This should also
help to abort the concurrent active scan/p2p-scan operations.
