90e478aa0a DPP2: Use the PFS fallback if multiple key_mgmt values are enabled
Previously this fallback from PFS enabled to disabled (and back to
enabled) was used only if the local network profile used key_mgmt=DPP,
i.e., did not enable another other AKM. That leaves out some valid cases
since the local network profile could actually enable both DPP and SAE.
Extend this check to accept cases DPP AKM is enabled and it was selected
for the connection even if there other enabled AKMs.

93a73ce028 MSCS: Fix issues due to incorrect usage of wpa_hexdump_buf()
Previously wpabuf_head() of the buffer is passed to wpa_hexdump_buf()
instead of the wpabuf struct itself and it was causing wpa_supplicant to
crash. Fix this by using the correct pointer in the debug prints.

1733e356e4 dpp-nfc: Fix handover client wait for receiving handover select
This was supposed to wait for up to 3.0 seconds for the handover select,
but the incorrect loop terminated ended up limiting this to a single
iteration of 0.1 second wait. This was too fast for some cases like the
AP mode operation where it may take significant time to enable the radio
for listening to DPP authentication messages.

Fix the loop to allow that full three second wait for the response to be
used. In addition, report the amount of time it takes to receive the
response.

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

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).

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.

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.

5058f771d9 DPP2: Allow station to require or not allow PFS
The new wpa_supplicant network profile parameter dpp_pfs can be used to
specify how PFS is applied to associations. The default behavior
(dpp_pfs=0) remains same as it was previously, i.e., try to use PFS if
the AP supports it. PFS use can now be required (dpp_pfs=1) or disabled
(dpp_pfs=2).

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.

22f0318dbd Interpolate rate calculation functions
Make max_*_rate() functions and rate calculation at the beginning of
wpas_get_est_tpt() more continuous. In wpa_supplicant_need_to_roam(), we
compare these values to make a roaming decision. However, at certain
SNRs, we see unrealistically large jumps in estimated throughput
according to these functions, leading us to make incorrect roaming
decisions. Perform linear interpolation where applicable to more
accurately reflect actual throughput.

Example:
wlan0: Current BSS: 88:3d:24:b4:95:d2 freq=2412 level=-69 snr=20 est_throughput=54000
wlan0: Selected BSS: 88:3d:24:b4:89:9e freq=2417 level=-67 snr=22 est_throughput=63500
wlan0: Using signal poll values for the current BSS: level=-69 snr=20 est_throughput=54000
wlan0: Allow reassociation - selected BSS has better estimated throughput

2 dB increase in RSSI likely isn't responsible for a 17% increase in
throughput.

1d9cff86bd Multi-AP: Set 4-address mode after network selection
Split multi_ap_process_assoc_resp() to set 4-address mode after network
selection. Previously, wpa_s->current_ssid might have been NULL in some
cases and that would have resulted in 4-address mode not getting enabled
properly.

2b9713d616 Fill the current opclass in (Re)AssocRequest depending on HT/VHT IEs
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.

1f13c1393c mesh: Fix CONFIG_HT_OVERRIDES build without CONFIG_VHT_OVERRIDES
Commit e5a9b1e8a3 ("mesh: Implement use of VHT20 config in mesh mode")
introduced the possibility to check the disable_vht param. However, this
entry is only available when CONFIG_VHT_OVERRIDES is enabled and as
such, this broke the build for some cases.

Fix this by encapsulating VHT property with the proper CONFIG entry.

52efde2aaa WPS: Do not set auth_alg=OPEN for PSK+SAE case
When wps_cred_add_sae=1 is used, WPS_AUTH_WPA2PSK credential gets
converted to enabling both PSK and SAE AKMs. However, this case was
still hardcoded auth_alg=OPEN which is not really correct for SAE. While
the SME-in-wpa_supplicant case can handle that, the SME-in-driver case
might not. Remove the unnecessary auth_alg=OPEN configuration to get the
normal PSK+SAE configuration enabled for the network profile.

fe0429a589 Replace systemd install Alias with WantedBy
According to the systemd documentation "WantedBy=foo.service in a
service bar.service is mostly equivalent to
Alias=foo.service.wants/bar.service in the same file." However,
this is not really the intended purpose of install Aliases.

f4bf6a5d44 OWE: Allow BSS entry with different SSID to be used in transition mode
Similarly to the wpa_supplicant_select_config() case,
wpa_get_beacon_ie() needs to handle the special case for OWE transition
mode where the SSID in the network profile does not match the SSID of
the OWE BSS (that has a hidden, random SSID). Accept such a BSS in case
the current scan results needs to be fetched for verifying EAPOL-Key msg
3/4 IEs.

3c73811507 OWE: Mark BSS for transition mode based on active OWE network profiles
It is possible for the hidden OWE BSS to be found based on SSID-specific
scan (e.g., from the special OWE scan mechanism). In that sequence, the
previously used learning of OWE BSS was skipped since the SSID was
already present in the BSS entry. This could result in not being able to
find a matching BSS entry for the OWE BSS in transition mode.

Fix this by adding the BSS flag for transition mode based on SSID
matching against currently enabled OWE network profiles in addition to
the previous mechanism.

ecb5219d8c OWE: Avoid incorrect profile update in transition mode
The "unexpected" change of SSID between the current network profile
(which uses the SSID from the open BSS in OWE transition mode) and the
association with the OWE BSS (which uses a random, hidden SSID) resulted
in wpa_supplicant incorrectly determining that this was a
driver-initiated BSS selection ("Driver-initiated BSS selection changed
the SSID to <the random SSID from OWE BSS>" in debug log).

This ended up with updating security parameters based on the network
profile inwpa_supplicant_set_suites() instead of using the already
discovered information from scan results. In particular, this cleared
the RSN supplicant state machine information of AP RSNE and resulted in
having to fetch the scan results for the current BSS when processing
EAPOL-Key msg 3/4.

Fix this by recognizing the special case for OWE transition mode where
the SSID for the associated AP does not actually match the SSID in the
network profile.
