This was already done for most driver cases, but it is possible that the
BSSID/frequency is not forced if the driver reports BSS selection
capability (e.g., NL80211_ATTR_ROAM_SUPPORT). That could potentially
result in the driver ignoring the BSSID/frequency hint and associating
with another (incorrect) AP for the WPS provisioning step if that
another AP in the same ESS is more preferred (e.g., better signal
strength) by the driver and only one of the APs (the not preferred one)
is in active WPS registrar state.
While most drivers follow the BSSID hint for the initial connection to
an ESS, not doing it here for the WPS provisioning would break the
protocol. Fix this by enforcing a single BSSID/frequency to disallow the
driver from selecting an incorrect AP for the WPS provisioning
association.

PNO is sometimes restarted due to changes in scan parameters
(e.g., selected network changed or MAC randomization being
enabled/disabled). Restart is done by stopping PNO and immediately
starting it again. This may result in the SCHED_SCAN_STOPPED event being
received after the request for new PNO, which will make wpa_supplicant
believe PNO is not active although it is actually is. As a result, the
next request to start PNO will fail because PNO is active and should be
stopped first.
Fix this by deferring the request to start PNO until the
SCHED_SCAN_STOPPED event is received in case sched_scan is being
stopped.

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.

This signal sends the peer properties to applications for discovered

because the current DeviceFound signal provides only the peer object
path. If there are many peers in range there will be many DeviceFound
signals and for each DeviceFound signal, applications would need to use
GetAll to fetch peer properties. Doing this many times would create
extra load over application as well as over wpa_supplicant, so it is
better to send peer properties in the event so that applications can
extract found peer information without extra steps.
The existing DeviceFound signal is left as-is to avoid changing its

that the wildcard BSSID value is used in Public Action frames that are
transmitted to a STA that is not a member of the same BSS.
wpa_supplicant used to use the actual BSSID value for all such frames
regardless of whether the destination STA is a member of the BSS.
P2P does not follow this rule, so P2P Public Action frame construction
must not be changed. However, the cases using GAS/ANQP for non-P2P
purposes should follow the standard requirements.
Unfortunately, there are deployed AP implementations that do not reply
to a GAS request sent using the wildcard BSSID value. The previously
used behavior (Address3 = AP BSSID even when not associated) continues
to be the default, but the IEEE 802.11 standard compliant addressing
behavior can now be configured with gas_address3=1.

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.

When the P2P Device interface is used and an existing interface is used

1. Copy the NFC key data only if it was not set in the configuration

2. The WPS string fields are set only if they were not previously set

Commit dd271857a5 ('Skip normal scan when

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).

This patch add functionality of mesh SAE PMKSA caching. If the local STA

If the peer does not support PMKSA caching or does not have the local

of the peer will be removed. Then STA retries with ordinary SAE
authentication.
If the peer does not support PMKSA caching and the local STA uses
no_auto_peer=1, the local STA can not retry SAE authentication because
NEW_PEER_CANDIDATE event cannot start SAE authentication when
no_auto_peer=1. So this patch extends MESH_PEER_ADD command to use

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 does more than intended; apart from denying messages to that
particular interface it also denies all messages non-qualified with an
interface globally. This blocks messages completely unrelated to
wpa_supplicant, such as NetworkManager communication with the VPN
plugins.
From the dbus-daemon manual:
Be careful with send_interface/receive_interface, because the
interface field in messages is optional. In particular, do NOT
specify <deny send_interface="org.foo.Bar"/>! This will cause
no-interface messages to be blocked for all services, which is almost
certainly not what you intended. Always use rules of the form: <deny
send_interface="org.foo.Bar" send_destination="org.foo.Service"/>
We can just safely remove those rules, since we're sufficiently
protected by the send_destination matches and method calls are
disallowed by default anyway.

When a mesh point reconnects by starting from Authentication frame
sequence, the plink count was not decremented from its last connection.
This resulted in leaking peer link count and causing wpa_supplicant to
reject the connection after max_peer_links (default: 99) reconnects.
This was reproduced by pre-configuring 2 mesh points with mesh
credentials. Boot both mesh points and make sure they connect to each
other. Then in a loop reboot one of the mesh points after it
successfully connects while leaving the other mesh point up and running.
After 99 iterations the supplicant on mesh point that is not rebooting
will reject the connection request from the other mesh point.
Fix this by decrementing num_plinks when freeing a STA entry that is
still in PLINK_ESTAB state.

In cases where the bandwidth is not set when starting an AP/P2P GO,

Fix this by changing the AP/P2P GO configuration not to use VHT channels

environment with interference or other traffic. Make this less likely to
fail the full exchange by trying full GAS query again and using longer
wait time on the GAS comeback exchanges.

When exchanging GAS frames with the AP, the initial response from the AP
may take a while to come, since the AP may need to fetch the info from a
server. The next fragments/comeback response frames should take much
less time since the AP already has all of the info, so the wait time
for these frames can be reduced.
In addition, some drivers, e.g., mac80211, try to combine ROC based flows,
to improve medium utilization. For example, if the requested ROC fits
entirely in a previous requested ROC they can be combined. Thus, reducing
the wait time for the next frames can improve medium utilization.
Shorten the duration of GAS comeback to improve medium utilization and
overall GAS exchange times.

Commit 2c0d0ae370 ('GAS: End
remain-on-channel due to delayed GAS comeback request') started ending
the remain-on-channel operation between the initial request and the
following comeback request. However, it did not check or update the
offchannel_tx_started variable. While this alone would not necessarily
be problematic, this makes it more difficult to optimize wait time for
offchannel TX operations, so make sure the internal tracking variable
gets updated.

Such a pending frame cannot be valid anymore, so drop it instead of
risking of using an unexpected EAPOL frame after association if a
previous association received one at the end and the new association can
happen within 100 ms.

Only one of the icon entries with a matching BSSID and file name can be
fetched from wpa_supplicant and as such, there is no need to maintain
the old data if it was not explicitly deleted before running a new fetch
for the same BSSID and icon. Remove older duplicated entries whenever
completing a pending icon fetch to optimize memory use.

This adds a new command based Hotspot 2.0 icon retrieval option.
In short, here is the new command sequence:
1. REQ_HS20_ICON <bssid> <file-name>
2. event: RX-HS20-ICON <bssid> <file-name> <size>
3. GET_HS20_ICON <bssid> <file-name> <offset> <size>
(if needed, repeat with larger offset values until full icon is
fetched)
5. DEL_HS20_ICON <bssid> <file-name>
REQ_HS20_ICON is a new command that is analogous to HS20_ICON_REQUEST
with the slight difference that an entry to store the icon in memory is
prepared. The RX-HS20-ICON event has been augmented with BSSID,
file-name and size, and GET_HS20_ICON is used to retrieve a chunk of up
to <size> bytes of icon data at offset <offset>. Each chunk is returned
as a base64 encoded fragment, preceded by "HS20-ICON-DATA", BSSID, and
file-name as well as the starting offset of the data.
If there is no entry prepared for the icon when the ANQP result comes
back, hs20_process_icon_binary_file falls back to legacy behavior.
Finally the DEL_HS20_ICON command deletes (all) icons associated with
BSSID and file-name (there could be several if retries are used and they
have different dialog tokens).

SIGNAL_MONITOR THRESHOLD=DD HYSTERESIS=DD command will request signal
strength monitoring events based on there having been requested amount
of drop in the signal strength. The threshold value is the RSSI
threshold in dBm for the event to be sent. 0 threshold can be used to
disable monitoring. The hysteresis value is RSSI hysteresis in dB to
specify the minimum amount of change before a consecutive event is
reported.
With nl80211 driver interface, these values map to the
NL80211_CMD_SET_CQM command with NL80211_ATTR_CQM_RSSI_THOLD and
NL80211_ATTR_CQM_RSSI_HYST attributes to the driver.
This command cannot be used when bgscan module is in use since that
depends on being able to control the connection monitoring parameters.

During the sequence of exchanging GAS frames with the AP, the AP can
request to come back in X amount of time and resend the GAS request.
Previously, wpa_supplicant did not terminate the remain-on-channel
session, but rather waited until the requested comeback delay had
expired, and then tried to send the GAS frame (potentially to save the
time that is required to schedule a new remain on channel flow).
This might cause unnecessary idle time (can be close to 1000 ms) in
which the device might be off-channel. Ending the current
remain-on-channel session and then rescheduling makes better usage of
the time in this case.
End remain-on-channel session due to receiving a delayed GAS comeback
request from the AP.

wpa_ctrl_command_sta(), called by the "ALL_STA" handler, didn't consider
ifname_prefix, resulting in various commands being sent to the global
control interface, rather than the specified interface when IFNAME=
prefix was used.
This in turn caused the unexpected "UNKNOWN COMMAND" result be
considered as valid station, resulting in infinite loop while trying to
get all stations.
Fix it by considering ifname_prefix, similarly to _wpa_ctrl_command().

Previously, when wpa_supplicant received bgscan results with a preferred
network, it connected to that network without disconnecting from the
previous one. This might result in an inconsistent state of upper

Fix this by disconnecting from the current AP before connecting to the
new one when the network profile changes and there is an existing

If scan results arrive during the connection process, the network
selection function was called, interrupting the current connection.
While a regular scan is mutually exclusive with connection establishment
via the nature of radio work, there's no such protection for scheduled
scan. Prevent network selection while a connection is in progress.

The full VHT channel information was not set in the hostapd data
structures which resulted in incorrect information (all zeros) being
used when building the VHT Operation element for peering messages while
the actual driver mode was set with the full details. We did not seem to
use the VHT information from peering messages, so this does not change
behavior with another wpa_supplicant-based mesh implementation. Anyway,
these elements should match the ones used in Beacon frames.

This allows the internal TLS client implementation to accept
CertificateStatus message from the server when trying to use OCSP

This adds support for optional functionality to validate server
certificate chain in TLS-based EAP methods in an external program.
wpa_supplicant control interface is used to indicate when such
validation is needed and what the result of the external validation is.
This external validation can extend or replace the internal validation.
When ca_cert or ca_path parameter is set, the internal validation is
used. If these parameters are omitted, only the external validation is
used. It needs to be understood that leaving those parameters out will
disable most of the validation steps done with the TLS library and that
configuration is not really recommend.
By default, the external validation is not used. It can be enabled by
addingtls_ext_cert_check=1 into the network profile phase1 parameter.
When enabled, external validation is required through the CTRL-REQ/RSP
mechanism similarly to other EAP authentication parameters through the
control interface.
The request to perform external validation is indicated by the following
event:
CTRL-REQ-EXT_CERT_CHECK-<id>:External server certificate validation needed for SSID <ssid>
Before that event, the server certificate chain is provided with the
CTRL-EVENT-EAP-PEER-CERT events that include the cert=<hexdump>
parameter. depth=# indicates which certificate is in question (0 for the
server certificate, 1 for its issues, and so on).
The result of the external validation is provided with the following
command:
CTRL-RSP-EXT_CERT_CHECK-<id>:<good|bad>
It should be noted that this is currently enabled only for OpenSSL (and
BoringSSL/LibreSSL). Due to the constraints in the library API, the
validation result from external processing cannot be reported cleanly
with TLS alert. In other words, if the external validation reject the
server certificate chain, the pending TLS handshake is terminated
without sending more messages to the server.

This was already working for the case where a separate group interface
is used due to the recent commit
328f49acfe ('P2P: Complete group formation

Commit f05cee9714 ('P2P: Clear
p2p_in_invitation on cancel') added a wpas_p2p_cancel() case to call
wpas_p2p_group_formation_failed() if wpa_s->p2p_in_invitation is set.
This is done in a loop going through wpa_s->next pointers. However, the
call here can result in removing the interface and freeing wpa_s. The
following attempt to read wpa_s->next is from freed memory and that can
result in process termination when using a separate P2P group interface
and issuing P2P_CANCEL on a group that was started through re-invocation
of a persistent group.
The recent commit 328f49acfe ('P2P:
Complete group formation on client data connection') "fixed" this by
accident since wpa_s->p2p_in_invitation gets cleared in the sequence
that could hit this issue and this results in P2P_CANCEL getting
rejected. However, the real bug here is in the loop that continues after
possible wpa_s instance deletion. Fix that by breaking out of the loop.

This was already the case in the GO role where the first client
connection is waited before marking
wpa_s->p2p_go_group_formation_completed = 1 and clearing
wpa_s->global->p2p_group_formation. However, in the P2P Client role,
that was done already at the completion of the WPS exchange. This can be
problematic since group formation timeout may still try to clear the
group and with wpa_s->global->p2p_group_formation == NULL, the correct
group interface may not be found.
Fix this by postponing clearing of wpa_s->global->p2p_group_formation on
the P2P Client side until the data connection has been completed and
group is declared started.
