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

However, some applications expect the REGDOM_CHANGE event to be

To resolve this, when processing NL80211_CMD_WIPHY_REG_CHANGE,

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.

PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for IEEE 802.11ad devices.
Add a new "pbss" argument to network block. The argument is used
in the following scenarios:
1. When network has mode=2 (AP), when pbss flag is set will start
as a PCP instead of an AP.
2. When network has mode=0 (station), when pbss flag is set will
connect to PCP instead of AP.
The function wpa_scan_res_match() was modified to match BSS according to

is set it will match only PCPs, and when it is clear it will match only
APs.

It is possible for driver-based BSS selection to end up reassociating
back to the current AP. If wpa_supplicant preferred another BSS, it
would have updated the internal knowledge of the AP's WPA/RSN IE when
requesting a new connection. In the special case of existing association
and new association being with the same BSS that is different from the
wpa_supplicant preference, association event processing skipped the
WPA/RSN IE update. This could result in the following 4-way handshake
getting rejected due to incorrectly detected mismatch with AP's RSN/WPA
IE between Beacon/Probe Response frame and EAPOL-Key msg 3/4.
Fix this by updating the AP WPA/RSN IE on all association events when
driver-based BSS selection is used regardless of whether the BSSID
changes. This could also cover a theoretical case of the AP changing its
RSN/WPA IE at the very moment we try to reassociate back to the same

It was possible for auth/assoc timeout/failure event from the driver to
result in unexpected processing during mesh group setup if that
operation was started before the previously started driver operation to
association/connect had completed. Since those events cannot happen in
mesh cases, ignore them to avoid issues due to this corner case.
For example, monitor_iface_unknown_sta followed by wpas_mesh_secure test
case resulted in failure without this change.

Send link measurement response when a request is received. Advertise
only RCPI, computing it from the RSSI of the request. The TX power field
is left to be filled by the driver. All other fields are not published.

Add the ability to send a Neighbor Report Request (part of
RRM). Requester is then notified once the report arrives.

In case the AP we are associating with advertises support for RRM,
advertise our own RRM support in the (Re)Association Request frame. This
is done by adding an RRM Capabilities IE. The underlying driver is
expected to further add a Power Capabilities IE to the request, and set
the Radio Measurement flag in the Capability Info field. At this point
the RRM Capabilities IE advertises no measurement support.

If the last scans are recent (for now, less than ten seconds old), use
them instead of triggering a new scan when a BSS Transition Management
Request frame is received. As a fallback, allow a new scan to be
triggered if no matches were found.

The mesh peering manager establishes and maintains links among
mesh peers, tracking each peer link via a finite state machine.
This implementation supports open mesh peerings.

This commit introduces a QCA vendor command and event to provide an
option to use extended versions of the nl80211 connect/roam operations
in a way that allows drivers to offload key management operations to the
driver/firmware.

If "STA_AUTOCONNECT 0" has been used to disable automatic connection on
disconnection event and the driver indicates multiple disconnection
events for the disconnection from the current AP when WPS is started, it
could have been possible to hit a case where wpa_s->disconnected was set
to 1 during WPS processing and the following scan result processing
would stop the operation.
wpa_s->key_mgmt == WPA_KEY_MGMT_WPS check was trying to avoid to skip
autoconnect when WPS was in use, but that does not seem to work anymore.
Fix this by checking through wpas_wps_searching() as well to avoid
setting wpa_s->disconnect = 1 when there is an ongoing WPS operation.

The commit 5cd4740580 has rearranged the
update scan results code and hence the IEs were not getting updated
properly for ap_scan=1 case. This can result in a 4-way handshake
failure in the roaming case (IE mismatch in 3/4 EAPOL). Fix this by
updating the scan results even if ap_scan=1 is used and network does not
need to get reselected based on association information.
