192ad3d730 Interworking: Clear SCANNING state if no match found
Previously, it was possible for wpa_state to be left at SCANNING if
INTERWORKING_SELECT command failed to find any match. Now the state is
set to DISCONNECTED if the operation terminates because of no matching
networks.

a51c40aa35 P2P: Fix regression in start-GO/AP through a "fake" scan
Commit 3f9ebc439c ('P2P: Allow AP/GO
interface to be started while P2P-in-progress') moved the
wpa_s->connect_without_scan and wpa_s->last_scan_req checks to an
earlier place within the wpa_supplicant_scan() function without
adjusting wpa_s->last_scan_req. This variable was set between the old
and new location, so the new location needs to use wpa_s->scan_req.

This fixes an issue where AP/GO operations were not properly started in
some operation sequence. Instead, a station mode scan was executed. This
issue could be triggered, e.g., by running the no_go_freq test case
followed by autogo_random_channel.

1772d348ea P2P: Fix interface deinit for failed group interface initialization
wpa_supplicant_deinit_iface() ends up removing all P2P groups if the
removed interface is the parent interface. This is correct behavior in
general, but this resulted in issues in the new group interface
initialization error path since wpa_s->parent was not assigned before
hitting this check. Fix this by assigning wpa_s->parent as part of

There are number of cases where wpa_supplicant requests the current

0d2030ee20 Use estimated throughput to improve roaming selection
Previously, within-ESS roaming was skipped if the selected BSS did not
have a higher signal strength than the current BSS regardless of AP
capabilities. This could result in not moving to a BSS that would
provide higher throughput, e.g., due to larger channel bandwidth or
higher rates (HT/VHT MCS).

Use estimated throughput information from scan result processing to
allow within-ESS roaming if the selected BSS is likely to provide better
throughput even if the current BSS has larger RSSI.

a1b790eb9d Select AP based on estimated maximum throughput
This modifies the BSS selection routines to calculate SNR and estimated
throughput for each scan result and then use the estimated throughput as
a criteria for sorting the results. This extends the earlier design by
taking into account higher throughput rates if both the AP and local
device supports HT20, HT40, or VHT80. In addition, the maximum rate is
restricted based on SNR.

In practice, this gives significantly higher probability of selecting
HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not
low enough to prevent higher MCS use.

71d77adb6d Update current BSS level when signal change event occurs
When an EVENT_SIGNAL_CHANGE occurs the bgscan is informed about this
change but the new RSSI value is not stored. In consequence, when
roaming candidates are evaluated, the RSSI value of the current BSS used
to compare is an old one obtained during the last scan rather than the
new one given by the signal change event. This leads sometimes to bad
decision when selecting a new BSS for roaming.

This patch solves the issue by updating the current BSS level when
receiving a signal change event in order to have a very up-to-date
current signal value when choosing an new BSS.

f91a512f1f Add INTERWORKING_ADD_NETWORK command
This can be used to provide more control to upper layers on network
blocks generated as part of Interworking network selection.
INTERWORKING_ADD_NETWORK behaves otherwise identically to
INTERWORKING_CONNECT, but it does not request a new connection after
having added the network block and it returns the network id of the
added network.

INTERWORKING_ADD_NETWORK followed by REASSOCIATE would behave more or
less identically to INTERWORKING_CONNECT, but this allows the created
network profile to be modified, if desired, and/or stored externally.
SELECT_NETWORK can also be used with the network id returned from
INTERWORKING_ADD_NETWORK to enforce that specific network profile to be
used for the next connection (though, it should be noted that this
behavior may not meet all Hotspot 2.0 requirements if there were other
enabled networks that could have higher priority).

b0e669beeb P2P: Fix P2P_CONNECT-auto fallback to GO Neg with group interface
If a separate P2P group interface was used, P2P_CONNECT-auto fallback to
GO Negotiation could result in use of freed memory and segmentation
fault. This happened in cases where the peer GO was found in some old
scans, but not in the first scan triggered by the P2P_CONNECT-auto
command ("P2P: Peer was found running GO in older scan -> try to join
the group" shows up in the debug log). In addition, the GO would still
need to reply to PD Request to allow this code path to be triggered.

When five scans for the GO were completed in this sequence, the P2P
group interface was removed as part of falling back to GO Negotiation.
However, that ended up dereferencing the freed wpa_s instance at the end
of scan event processing. Fix this by reordering code a bit and breaking
out from EVENT_SCAN_RESULTS processing if the interface could have been
removed.

bf51f4f82b mesh: Fix remaining BLOCKED state after SAE auth failure
When SAE authentication fails, wpa_supplicant retries four times. If all
the retries result in failure, SAE state machine enters BLOCKED state.
Once it enters this state, wpa_supplicant doesn't retry connection. This
commit allow connection retries even if the state machine entered
BLOCKED state.

There could be an opinion "Is this patch needed? User could know the SAE
state machine is in the BLOCKED mode by MESH-SAE-AUTH-BLOCKED event.
Then user can retry connection. By user action, SAE state machine can
change the state from BLOCKED to another.". Yes, this is a true at the
joining mesh STA. However, a STA that is already a member of existing
mesh BSS should not retry connection because if the joining mesh STA
used wrong password, all the existing STA should do something from UI to
retry connection.
