ca4fa867d3 Enable PMF automatically if OCV is enabled
OCV cannot be used without PMF and such a configuration were to be used
with wpa_supplicant, the AP would reject the association. hostapd is
already enabling PMF automatically whenever OCV is being enabled, so do
the same with wpa_supplicant.

65c8633d90 Allow a lower priority BSS to be tried after network disabling
If a higher priority BSS has invalid security parameters, e.g., an
invalid SAE password, and a lower priority BSS is discovered only after
the local network profile has been temporarily disabled, the BSSID
ignoring mechanism is not sufficient to allow the lower priority BSS to
be tried and all consecutive attempts will continue to use the higher
priority BSS. This might prevent connection in some unexpected cases
with invalid network configuration.

Extend BSSID ignoring mechanism to work in this type of a case by
ignoring the BSSID that resulted in disabling the SSID temporarily
during the first connection attempt after having re-enabled the SSID.
This allows a lower priority BSS, if any is available in scan results,
to be tried next to see if it might have working security parameters.

bbe5f0c1eb FT: Do not try to use FT protocol between mobility domains
wpa_supplicant has support for only a single FT key hierarchy and as
such, cannot use more than a single mobility domain at a time. Do not
allow FT protocol to be started if there is a request to reassociate to
a different BSS within the same ESS if that BSS is in a different
mobility domain. This results in the initial mobility domain association
being used whenever moving to another mobility domain.

While it would be possible to add support for multiple FT key hierachies
and multiple mobility domains in theory, there does not yet seem to be
sufficient justification to add the complexity needed for that due to
limited, if any, deployment of such networks. As such, it is simplest to
just prevent these attempts for now and start with a clean initial
mobility domain association.

b92f61885c Don't use default RSNE/RSNXE when the driver indicates cross SSID roaming
During cross SSID roaming wpa_supplicant ended up using the default
RSNE/RSNXE in EAPOL-Key msg 2/4 though the driver indicated
(Re)Association Request frame elements without RSNE/RSNXE. This causes
RSNE/RSNXE mismatch between (Re)Association Request frame and EAPOL-Key
msg 2/4.

To avoid this skip copying the default RSNE/RSNXE if the driver
indicates the actually used (Re)Association Request frame elements in
the association event.

c6f8af507e Add option to disable SAE key_mgmt without PMF
Add the `sae_check_mfp` global option to limit SAE when PMF will
not be selected for the connection.
With this option SAE is avoided when the hardware is not capable
of PMF due to missing ciphers.
With this option SAE is avoided on capable hardware when the AP
does not enable PMF.

Allows falling back to PSK on drivers with the
WPA_DRIVER_FLAGS_SAE capability but do not support the BIP cipher
necessary for PMF. This enables configurations that can fall back
to WPA-PSK and avoid problems associating with APs configured
with `sae_require_mfp=1`.

Useful when `pmf=1` and `sae_check_mfp=1` are enabled and networks
are configured with ieee80211w=3 (default) and key_mgmt="WPA-PSK SAE".
In this configuration if the device is unable to use PMF due to
lacking BIP group ciphers it will avoid SAE and fallback to
WPA-PSK for that connection.

2e73394426 P2P: Discount current operating frequency when scanning new connection
When scanning for a new connection, we currently optimize by scanning
all frequencies only when our MCC capabilities will allow an additional
operating frequency, and scan only the existing operating frequencies
otherwise. This is problematic when there the current operating
frequency singularly accounts for one of the shared radio frequencies
because we should be able to switch operating frequencies without adding
to the channel count. Fix this.

6b461f68c7 Set current_ssid before changing state to ASSOCIATING
For hidden GBK encoding of a Chinese SSID, both the UTF-8 and GBK
encoding profiles are added into wpa_supplicant to make sure the
connection succeeds. In this situation, wpa_supplicant_select_network()
will not be called so current_ssid is NULL when association begins.

Android monitors the WPA_EVENT_STATE_CHANGE event to get the SSID and
BSSID. When connecting to a Chinese SSID, in case of association
rejection happens, Android will report null SSID to OEM APP because
current_ssid is updated after wpa_supplicant_set_state(wpa_s,
WPA_ASSOCIATING), which may cause confusion.

Fix this by setting the current_ssid before changing state to
ASSOCIATING.
