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.

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

might not. Remove the unnecessary auth_alg=OPEN configuration to get the

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.
Signed-off-by: Jouni Malinen <j@w1.fi>
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.

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.

While the WSC specification requires the Enrollee to stop PBC
provisioning if the scan sees multiple APs in active PBC mode, this is
problematic due to some deployed devices continuing to advertise PBC
mode for extended duration (or even permanently). Such an environment
will still need to prevent wildcard AP selection with PBC since an
incorrect device could be selected. However, if the Enrollee device has
been explicitly requested to connect to a specific AP based on its
BSSID, the other APs in scan results can be ignored without affecting
which AP would be selected (only the one matching the specified BSSID is
acceptable).
Start filtering scan results for PBC session overlap check based on the
locally specified constraint on the BSSID, if one is set. This allows
PBC to be used with "WPS_PBC <BSSID>" command in environment where
another AP device is claiming to be in active PBC mode while "WPS_PBC"
command will still continue to reject provisioning since the correct AP
cannot be selected.
This will also cover the P2P cases where P2P_CONNECT is used to start or
authorize GO Negotiation and joining-a-GO with a specific P2P GO
Interface Address (BSSID).

There does not seem to be a good reason for using the different IFACE=
prefix on the UDP control interface. This got added when the UDP
interface in wpa_supplicant was extended in commit f0e5d3b5c6
("wpa_supplicant: Share attach/detach/send UDP ctrl_iface functions")
and that was then extended to hostapd in commit e920805685 ("hostapd:

Replace the IFACE= prefix in UDP case with IFNAME= to be consistent with
the UNIX domain socket based control interface.

Rekeying a pairwise key using only keyid 0 (PTK0 rekey) has many broken

to leaking clear text MPDUs.
