Some driver interfaces (e.g., wext) might not include the
data->scan_info information and data could be NULL here. Do not try to
call the RRM handler in this case since that would dereference the NULL
pointer when determining where scan_info is located and could
potentially result in trying to read from unexpected location if RRM is
enabled with a driver interface that does not support it.

According to IEEE Std 802.11-2016, 9.4.2.25 when fields of an RSNE are
not included, the default values are used. The cipher suite defaults
were hardcoded to CCMP in the previous implementation, but the default
is actually different for DMG: GCMP (per 9.4.2.25.2).
It is not possible to find out from the RSNE if the network is non-DMG
or DMG, so callers of wpa_parse_wpa_ie_rsn() need to handle this case
based on context, which can be different for each caller.
In order to fix this issue, add flags to the wpa_ie_data indicating
whether pairwise/group ciphers were included in the RSNE. Callers can
check these flags and fill in the appropriate ciphers. The
wpa_parse_wpa_ie_rsn() function still initializes the ciphers to CCMP by
default so existing callers will not break. This change also fixes some
callers which need to handle the DMG network case.

The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the backhaul STA needs to add
a Multi-AP IE to the WFA vendor extension element in the WSC M1 message
that indicates it supports the Multi-AP backhaul STA role. The Registrar
(if it support Multi-AP onboarding) will respond to that with a WSC M8
message that also contains the Multi-AP IE, and that contains the
credentials for the backhaul SSID (which may be different from the SSID
on which WPS is performed).
Introduce a new parameter to wpas_wps_start_pbc() and allow it to be
set via control interface's new multi_ap=1 parameter of WPS_PBC call.
multi_ap_backhaul_sta is set to 1 in the automatically created SSID.
Thus, if the AP does not support Multi-AP, association will fail and
WPS will be terminated.
Only wps_pbc is supported.
This commit adds the multi_ap argument only to the control socket
interface, not to the D-Bus interface.
Since WPS associates with the fronthaul BSS instead of the backhaul BSS,
we should not drop association if the AP announces fronthaul-only BSS.
Still, we should only do that in the specific case of WPS. Therefore,
add a check to multi_ap_process_assoc_resp() to allow association with a
fronthaul-only BSS if and only if key_mgmt contains WPS.

Add support for negotiating WNM Collocated Interference Reporting. This

interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.
For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".
For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems

more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic

unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".

reason, FILS authentication attempts with ERP fails and the previous

Address this by trying to use full (non-FILS) authentication when trying

complex cases, e.g., when STA is acting as an active slave with DFS
offload enabled and decided to start CAC after receiving CONNECT
command, in such a case the 10 second timeout is too small and
wpa_supplicant need to wait for CAC completion or CAC timeout (up to 10

Without such timeout modification wpa_supplicant will be unable to

That's because wpa_supplicant computed the PMKID using the wrong (old)
MAC address used during the scan. wpa_supplicant updates own_addr when
the interface goes up, as the MAC can only change while the interface
is down. However, drivers don't report all interface state changes:
for example the nl80211 driver may ignore a down-up cycle if the down
message is processed later, when the interface is already up. In such
cases, wpa_supplicant (and in particular, the EAP state machine) would
continue to use the old MAC.
Add a new driver event that notifies of MAC address changes while the
interface is active.

This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.
This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.
Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

This could result in hwsim test case failures due to unexpected BSS

This provides more details on BSS selection process in the debug log.
Previously, the BSSs that were not either the current or the selected
one were not necessarily printed at all. Now all BSSs that match the
currently selected network are listed with their frequency and signal

Previously, the estimated throughput was used to enable roaming to a
better AP. However, this information was not used when considering a
roam to an AP that has better signal strength, but smaller estimated
throughput. This could result in allowing roaming from 5 GHz band to 2.4
GHz band in cases where 2.4 GHz band has significantly higher signal
strength, but still a lower throughput estimate.
Make this less likely to happen by increasing/reducing the minimum
required signal strength difference based on the estimated throughputs
of the current and selected AP. In addition, add more details about the
selection process to the debug log to make it easier to determine whaty
happened and why.

Previously, a build without IBSS RSN support tried to start/join an IBSS
even if the profile was configured with RSN parameters. This does not
work and resulted in quite confusing debug log. Make this clearer by
explicitly checking for this case and reject the connection attempt with
a clearer debug log entry instead of trying something that is known to
fail.

Scan results were not propagated to all interfaces if scan results
started a new operation, in order to prevent concurrent operations. But
this can cause other interfaces to trigger a new scan when scan results
are already available. Instead, always notify other interfaces of the
scan results, but note that new operations are not allowed.

In some cases, after a sudden AP disappearing and reconnection to
another AP in the same ESS, if another scan occurs, wpa_supplicant might
try to roam to the old AP (if it was better ranked than the new one)
because it is still saved in BSS list and the blacklist entry was
cleared in previous reconnect. This attempt is going to fail if the AP
is not present anymore and it'll cause long disconnections.
Remove an AP that is probably out of range from the BSS list to avoid
such disconnections. In particular mac80211-based drivers use the
WLAN_REASON_DISASSOC_DUE_TO_INACTIVITY reason code in locally generated
disconnection events for cases where the AP does not reply anymore.

The P2P Device interface can only send Public Action frames. Non-Public
Action frames must be sent over a group interface. The previous
implementation sometimes tried to send non-Public Action frames such as
GO Discoverability over the P2P Device interface, however, the source
address of the frame was set to the group interface address so the code
in offchannel.c knew to select the correct interface for the TX.
The check breaks when the P2P Device and group interfaces have the same
MAC address. In this case the frame will be sent over the P2P Device
interface and the send will fail.
Fix this problem in two places:
1. In offchannel, route non-Public Action frames to the GO
interface when the above conditions are met.
2. When a TX_STATUS event arrives on such routed frame, it will
arrive on the GO interface but it must be handled by the P2P Device
interface since it has the relevant state logic.

The NL80211_CMD_WIPHY_REG_CHANGE can be handled by any of the
interfaces that are currently controlled by the wpa_supplicant.
However, some applications expect the REGDOM_CHANGE event to be
sent on the control interface of the initially added interface
(and do not expect the event on any of child interfaces).
To resolve this, when processing NL80211_CMD_WIPHY_REG_CHANGE,
find the highest parent in the chain, and use its control interface
to emit the CTRL-EVENT-REGDOM-CHANGE event.

Commit dd271857a5 ('Skip normal scan when
PNO is already in progress') fixed issues with normal scans getting
rejected by the driver when PNO scan is already running. The part about
skipping such a scan request is fine, but the part about clearing
wpa_s->pno back to 0 in EVENT_SCHED_SCAN_STOPPED handler is problematic.
If PNO is stopped ("SET pno 0") and then restarted ("SET pno 1")
immediately, it is possible for the EVENT_SCHED_SCAN_STOPPED event from
the stopping part to be received only after the new PNO instance has
been started. This would have resulted in clearing wpa_s->pno and the
driver and wpa_supplicant getting out of sync. This would then prevent
PNO from being stopped with "SET pno 0" (that fails if wpa_s->pno == 0).
Fix this race condition by reverting the wpa_s->pno = 0 addition from
the EVENT_SCHED_SCAN_STOPPED handler.
