e3570f5e1c dbus: Use current_bss to get correct group BSSID and frequency on client
When the P2P persistent group is provisioned out-of-band, i.e., add
persistent group with a known BSSID, SSID, passphrase, and frequency,
and start the group with GroupAdd dbus command, the group info fetched
on the cliend side has zero MAC address for BSSID and no value for
frequency. Fix this issue by getting that information from
wpa_s->current_bss instead of wpa_s->go_params.

5927455b8b MLD: Add support for disabled APs
An affiliated AP of an AP MLD can temporarily be disabled. Other
affiliated APs of the AP MLD indicate this in the Reduced Neighbor
Report (RNR) elements added to their Beacon and Probe Response frames.

When an affiliated AP is disabled, it should be included in the
association exchange, but can be activated only after it is enabled.

Add support identifying disabled APs and propagate the information
to the driver within the associate() callback.

88984bbb94 MLD STA: Update SAE PWE derivation in hunting-and-pecking loop case
Use AP MLD address instead of BSSID for PWE derivation during MLO

("wpa_supplicant: Use MLD address in SAE authentication"). While IEEE
P802.11be requires H2E to be used, there are deployed AP MLDs that do
not follow that requirement. This change to the hunting-and-pecking loop
case is needed for interoperability workarounds with such APs.

1efdba5fdc Handle PMKSA flush in the driver for SAE/OWE offload cases
For wpa_supplicant based SAE/OWE connection, the wpa_supplicant state
machine is aware of the PMKID created for a connection and this gets
removed when "REMOVE_NETWORK all" is called. However, when SAE/OWE
offload is enabled, wpa_supplicant is not aware of the PMKID generated
by the driver/firmware. So add PMKSA del indication to the driver from
remove_network context so that the driver can free PMKs associated with
the SSID.

bbb0d3a40e mesh: Add for_each_sta implementation in wpa_auth_callbacks
The wpa_auth_callbacks for mesh was missing a for_each_sta
implementation. This is an issue with pmksa cache, as when a cache entry
expires the for_each_sta callback is called in order to clear the pmksa
reference for all sta that was using this entry. Not having a
for_each_sta callback will prevent this cleanup to happen then a sta
could still use this pmksa entry even after it has been freed.

This used after free was not a problem up until recently where
dpp_pkhash is now stored in pmksa entry and retreived later on causing
crash with below backtrace:

b9c81e2005 MLD: Use MLD MAC address for deauthentication
When connecting, pending_bssid is set to the main link that we are
authenticating/associating on. Later on, the MLD MAC address will be
stored in the bssid, but we may also try to deauthenticate before we are

address.

As such, use the ap_mld_addr instead of pending_bssid if n_mld_links is
non-zero. This is the sensible thing to do and expected behavior on

4ff287e922 P2P: Do not skip updating BSS table when frequency is changed
BSS table is not updated when a non-P2P station runs a scan without P2P
IE in Probe Response frame, since that would remove P2P IE information.
However, this results also in not updating mandatory rates in Supported
Rates and BSS Membership Selectors element even though AP/GO changes
frequency from 2.4 GHz to 5 GHz band.

This is causing connection failure since BSS table has 1 Mbps as
mandatory rate for AP connection but minimum supported rate in 5 GHz
band is 6 Mbps.

To avoid connection failures in such cases, don't skip updating BSS
table when the BSS frequency is changed. This covers the most important
case addressed in commit ff57398fca ("P2P: Do not drop P2P IEs from
BSS table on non-P2P scans") while still allowing other changes to be
taken into account if the GO were to actually change channels (or band,
which would be the most likely case needing the update).

initial version used the incorrect drv_flags value and by doing so,
ended up using incorrect driver capabilities (DEAUTH_TX_STATUS,
BSS_SELECT, TDLS_SUPPORT) which could result in incorrect OWE
functionality for both AP and STA cases.

Fixes: d984c7b298 ("hostapd: Add support for OWE offload for STA/AP interface")
Fixes: da364180fb ("hostapd: Support 4-way handshake offload for AP/P2P GO")
