885097125c mesh: Fix peer link counting when removing a mesh peer
When removing a mesh peer with control interface commands (ACCEPT_ACL
DEL_MAC/DENY_ACL ADD_MAC/MESH_PEER_REMOVE) the plink count was not
decreased from its last connection. This resulted in peer link count
leakage and wpa_supplicant rejecting the connections after reaching
max_peer_links (default: 99).

Fix this by decreasing the plink count when removing a mesh peer which
is in PLINK_ESTAB state.

c9dc075fcd dpp-nfc: Fix connection handover renegotiation
The use of the alternative channel list did not work properly for the
case were both ends were trying to initiate the negotiated connection
handover. Fix this by always starting a new connection handover client
thread for sending the alternative proposal and ignoring peer messages
(likely something from the first attempt) during this modified attempt.

d0819a11cc FILS: Use FILS auth alg when connecting using PMKSA caching
When a PMKSA cache entry is available and used for connection with FILS
key management suite, use FILS authentication algorithm for connection
even if ERP keys are not available. This scenario may happen when
applications using wpa_supplicant cache persistently only PMKSA but not
ERP keys and reconfigures wpa_supplicant with PMKSA cache after
restarting wpa_supplicant.

The previous implementation correctly handles SME-in-wpa_supplicant
cases. However, SME-in-driver cases, complete FILS authentication
without PMKSA caching is performed.

Fix SME-in-driver behavior by setting authentication algorithm to
WPA_AUTH_ALG_FILS when connecting to a FILS AP using PMKSA caching.

cc2d03601b HS 2.0: Use global pmf=2 for the created network block
Previously, PMF support was enabled in optional mode (ieee80211w=1) for
Hotspot 2.0 network blocks automatically. This did not consider the
global PMF parameter and unconditionally changed that value to optional.
Since the newly added network block had an explicit ieee80211w
parameter, this overrode the global parameter. To make this less
surprising, use the global pmf parameter value to select whether to add
network blocks for Hotspot 2.0 with PMF being optionally enabled (pmf=0
or pmf=1) or required (pmf=2).

fcef598ea2 Do not try to connect with zero-length SSID
It was possible to find a BSS to local network profile match for a BSS
entry that has no known SSID when going through some of the SSID
wildcard cases. At leas the OWE transition mode case without BSSID match
could result in hitting this. Zero-length SSID (i.e., wildcard SSID) is
not valid in (Re)Association Request frame, so such an association will
fail. Skip such a BSS to avoid known-to-be-failing association attempts.

215b4d8a72 FT: Do not add PMKID to the driver for FT-EAP if caching is disabled
wpa_supplicant disables PMKSA caching with FT-EAP by default due to
known interoperability issues with APs. This is allowed only if the
network profile is explicitly enabling caching with
ft_eap_pmksa_caching=1. However, the PMKID for such PMKSA cache entries
was still being configured to the driver and it was possible for the
driver to build an RSNE with the PMKID for SME-in-driver cases. This
could result in hitting the interop issue with some APs.

Fix this by skipping PMKID configuration to the driver fot FT-EAP AKM if
ft_eap_pmksa_caching=1 is not used in the network profile so that the
driver and wpa_supplicant behavior are in sync for this.

Use key_mgmt_iftype instead of key_mgmt when the specific interface type
is known by the context of the operation.

Use per interface type AKM capabilities in capa.key_mgmt_iftype array
based on the wpa_supplicant context instead of using capa.key_mgmt to
determine the driver AKM capability.

0c5edededa DPP: Fix config exchange with gas_rand_mac_addr
Do not use a random MAC address for the GAS exchange that is used as
part of the DPP protocol exchange since that would break DPP.
Configurator expects the same MAC address to be used for DPP
Authentication exchange and DPP Configuration exchange (GAS).

Since the DPP Authentication exchange has already used the MAC address
configured on the interface, use of a random address for the GAS
exchange would not provide any additional privacy protection. If a
random MAC address needs to be used for this type of an exchange, that
random address would need to be first configured on the interface before
starting DPP exchange.

This does not change GAS query behavior for any other use case, i.e.,
the gas_rand_mac_addr configuration continues to apply to all the
Interworking/Hotspot 2.0 uses.
