7e608d1def P2P: Use the correct wpa_s interface to handle P2P state flush
A control interface call to flush the current state used the
current wpa_s to clear the P2P state even though it might not
be the interface controlling the P2P state.

Fix it by using the correct interface to flush the P2P state.

911942ee64 Add a test framework for various wpa_supplicant failure cases
For CONFIG_TESTING_OPTIONS=y builds, add a new test parameter than can
be used to trigger various error cases within wpa_supplicant operations
to make it easier to test error path processing. "SET test_failure
<val>" is used to set which operation fails. For now, 0 = no failures
and 1 = scan trigger fails with EBUSY. More operations can be added in
the future to extend coverage.

6c69991382 Make wpa_supplicant FLUSH command more likely to clear all BSS entries
Move the wpa_bss_flush() call to the end of the function to allow any
pending user of a BSS entry to be cleared before removing the unused
entries. There were number of cases where BSS entries could have been
left in the list and this resulted in some hwsim test failures.

783b2a977f Interworking: Fix INTERWORKING_CONNECT with zero-length SSID BSS entry
For Interworking connection to work, the SSID of the selected BSS needs
to be known to be able to associate with the AP. It was possible for the
scan results to include two BSS entries matching the BSSID when an
earlier scan with that AP has shown a hidden SSID configuration (e.g.,
when running hwsim test cases, but at least in theory, this could happen
with real use cases as well). When that happened, the incorrect BSS
entry may not have included RSN configuration and as such, it would get
rejected for Interworking connection.

Fix this by confirming that the selected BSS entry has a real SSID. If
not, try to find another BSS entry matching the same BSSID and use that,
if found with an SSID.

a156ffda61 Add support for testing memory allocation failures
The new control interface command TEST_ALLOC_FAIL and GET_ALLOC_FAIL can
now be used to trigger memory allocation failures for testing purposes.
TEST_ALLOC_FAIL sets a failure conditions with
<count>:func[;func][;func]... string and GET_ALLOC_FAIL returns the
current state using the same format. Whenever an allocation is made with
a matching backtrace of calling functions, the count is decremented by
one and once zero is reached, the allocation is forced to fail.

Function names can be prefixed with either '=' or '?' to get different
matching behavior. '=' requires this specific function to be the next
one in the backtrace (i.e., do not skip any other functions in the list
which is the default behavior). '?' allows the function to be optionally
present in the backtrace.

6b90deae4d TDLS: Propagate enable/disable channel-switch commands to driver
The supplicant code does not try to control the actual channel of the
radio at any point. It simply passes the target peer and channel
parameters to the driver. It's the driver's responsibility to
periodically initiate TDLS channel-switch operations when TDLS
channel-switching is enabled.

e69ae5ff31 Reject new SCAN commands if there is a pending request
FAIL-BUSY was already returned for the case where a scan had been
started, but with the radio work design, it would have been possible to
schedule multiple scan requests if a non-scan radio work was in
progress. Multiple back-to-back scans are not usually very helpful, so
reject this type of cases where the SCAN command would be used to build
such a sequence.

97cfe110dc Clear wpa_s->disconnected on ctrl_iface FLUSH
This is needed to get into more consistent state after the FLUSH
command. DISCONNECT followed by FLUSH could result in
wpa_s->disconnected being left to 1 and this resulted in a test failure,
e.g., when running wpas_ctrl_dup_network followed by
wpas_ctrl_enable_disable_network where the latter was expecting
ENABLE_NETWORK on a disabled network to connect automatically and that
does not happen if wpa_s->disconnected == 1.

Commit 86bd36f0d5 ("Add generic

where it miscalculates the length of memory to move using

c267753ba2 Add support for using random local MAC address
This adds experimental support for wpa_supplicant to assign random local
MAC addresses for both pre-association cases (scan, GAS/ANQP) and for
connections. MAC address policy for each part can be controlled
separately and the connection part can be set per network block.

This requires support from the driver to allow local MAC address to be
changed if random address policy is enabled. It should also be noted
that number of drivers would not support concurrent operations (e.g.,
P2P and station association) with random addresses in use for one or
both.

This functionality can be controlled with the global configuration
parameters mac_addr and preassoc_mac_addr which set the default MAC
address policies for connections and pre-association operations (scan
and GAS/ANQP while not connected). The global rand_addr_lifetime
parameter can be used to set the lifetime of a random MAC address in
seconds (default: 60 seconds). This is used to avoid unnecessarily
frequent MAC address changes since those are likely to result in driver
clearing most of its state. It should be noted that the random MAC
address does not expire during an ESS connection, i.e., this lifetime is
only for the case where the device is disconnected.

The mac_addr parameter can also be set in the network blocks to define
different behavior per network. For example, the global mac_addr=1 and
preassoc_mac_addr=1 settings and mac_addr=0 in a home network profile
would result in behavior where all scanning is performed using a random
MAC address while connections to new networks (e.g.,
Interworking/Hotspot 2.0) would use random address and connections to
the home network would use the permanent MAC address.

VENDOR_ELEM_GET <frame id>
VENDOR_ELEM_REMOVE <frame id> <hexdump of elem(s)>

The following frames are supported in this commit (additional frames can
be added in the future):

0 = Probe Request frame in P2P device discovery
1 = Probe Response frame from P2P Device role
2 = Probe Response frame from P2P GO
3 = Beacon frame from P2P GO

6 = GO Neg Req
7 = GO Neg Resp
8 = GO Neg Conf
9 = Invitation Request
10 = Invitation Response
11 = P2P Association Request
12 = P2P Association Response

One or more vendor element can be added/removed with the commands. The
hexdump of the element(s) needs to contain the full element (id, len,
payload) and the buffer needs to pass IE parsing requirements to be

e3bd6e9dc0 P2P: Use another interface operating channel as listen channel
Performing a P2P Device flow such as p2p_listen or
p2p_find, can degrade the performance of an active interface
connection, if the listen frequency is different than the
frequency used by that interface.

To reduce the effect of P2P Device flows on other interfaces,
try changing the listen channel of the P2P Device to match the
operating channel of one of the other active interfaces. This change
will be possible only in case that the listen channel is not forced
externally, and will be delayed to a point where the P2P Device
state machine is idle.

The optimization can be configured in the configuration file and
is disabled by default.

3d910ef497 Interworking: Prefer last added network during network selection
Previously, any network block could be used to select the BSS to connect
to when processing scan results after Interworking network selection.
This can result in somewhat unexpected network selection in cases where
credential preferences indicated that a specific network was selected,
but another network ended up getting used for the connection. While the
older networks continue to be valid, add special processing for this
initial post-interworking-connect case to get more consistent network
selection to match with the Interworking network selection result.

b3253ebb73 wpa_supplicant: Complete radio works on disable event
While testing rfkill blocking of a scanning interface, it
was seen that the ongoing scan never completes. This happens
since EVENT_SCAN_RESULTS is discarded on a disabled interface.

Fix this and also other possible radio work completion issues
by removing all the radio works (including started) of the
disabled interface.

To be able to remove already started radio works, make their
callbacks be reentrant with deinit flag (when the work
is started), so each radio work should be able to handle
its own termination.

cf70d2981d wpa_supplicant: Schedule PNO on completion of ongoing sched_scan
When start PNO request comes from control interface, wpa_supplicant
should wait until ongoing sched_scan (triggered by wpa_supplicant)
gets cancelled. Issuing cancel sched_scan and start PNO scan
one after another from pno_start() would lead wpa_supplicant to clear
wps->sched_scanning flag while getting sched_scan stopped event
from driver for cancel sched_scan request. In fact, PNO scan will
be in progress in driver and wpa_s->sched_scanning will not be set
in such cases.

In addition to this change, RSSI threshold limit is passed as part of
start sched_scan request. This was previously set only in pno_start(),
but the same parameter should be available for generic sched_scan calls
as well and this can now be reached through the new PNO start sequence.

f86d282f43 Handle legacy scan interruption of sched_scan/PNO
While starting from PNO start context, the scheduled scan was not
setting the flag wpa_s->scanning. This was resulting in the subsequent
SCAN command to proceed further and send command to nl80211/cfg80211.
The expected behavior of cancelling sched_scan was not happening here.

While sched_scan is in progress and a legacy scan comes on the
cli/socket, the sched_scan is cancelled and normal scan is allowed to
continue. However, sometimes sched_scan cancelled event comes a bit
delayed and we will send out the scan command before the wpa_s->scanning
is cleared. Instead, reschedule the incoming scan req if the
wpa_s->scanning shows that it is still in progress.

800d58721c TDLS: Provide external control to specify the peers for setup
There are use cases requesting the host driver to initiate the TDLS
setup with the peer only when configured by the external applications.
Thus, enable this control by tdls_external_control=1 and pass the
requisite information for the specific TDLS operation to the driver
on the request from such use cases.

This operation mode expects the driver to initiate TDLS link
automatically based on signal strength and traffic to a peer and tear
down links whenever they are not used or suitable due to signal strength
etc. The list of peers with which such operations are to be performed
are provided with the TDLS driver operations.

bbc6c729a5 P2P: Use group formation timeout on persistent group GO
Previously, GO considered the group to be fully re-invoked after
starting beaconing on successful invitation exchange. This would leave
the group running until idle timeout (which may not be enabled) or
explicit removal if the client fails to connect for any reason. Since
the client is expected to connect immediately after the invitation
exchange that ends with status=0 (i.e., either client initiated the
exchange or it responded with success), extend group formation timeout
to cover that period until the first successfully completed data
connection. This allows the GO to remove the group automatically if the
client devices does not connect within
P2P_MAX_INITIAL_CONN_WAIT_GO_REINVOKE (15) seconds.

When enabled, a default passphrase is still generated by the GO for

This gives more protection for the P2P group by preventing clients from
being able to derive the unicast keys used by other clients. This is

reliably without having to tear down the full group to do so.

f1a5263389 Maintain maximum blacklist count over list clear operations
wpas_connection_failed() uses the blacklist count to figure out a
suitable time to wait for the next scan. This mechanism did not work
properly in cases where the temporary blacklist gets cleared due to no
other BSSes being available. Address this by maintaining an additional
count of blacklisting values over wpa_blacklist_clear() calls. In
addition, add one more step in the count to timeout mapping to go to 10
second interval if more than four failures are seen.

96beff11d1 P2P: Allow discoverable interval for p2p_find to be configured
The new P2P_SET parameter disc_int can now be used to configure
discoverable interval for p2p_find operations. The format of the command
for setting the values is "P2P_SET disc_int <minDiscoverableInterval>
<maxDiscoverableInterval> <max TUs for discoverable interval>". The
first two parameters are given in units of 100 TUs (102.4 ms). The third
parameter can be used to further limit the interval into a specific TU
amount. If it is set to -1, no such additional limitation is enforced.
It should be noted that the P2P specification describes the random
Listen state interval to be in units of 100 TUs, so setting the max TU
value to anything else than -1 is not compliant with the specification
and should not be used in normal cases. The default parameters can be
set with "P2P_SET disc_int 1 3 -1".

The bssid and priority parameters in a network block do not have any
effect on the validity of a PMKSA cache entry, so avoid flushing the
PMKSA cache when only these parameters are changed. This is mainly
to allow forced roaming or network selection changes without causing
a disconnection if the changes are done during RSN association that
used EAP.

6407f4132f Add disallow_aps parameter to disallow BSSIDs/SSIDs
External programs can use this new parameter to prevent wpa_supplicant
from connecting to a list of BSSIDs and/or SSIDs. The disallowed BSSes
will still be visible in scan results and it is possible to run ANQP
operations with them, but BSS selection for connection will skip any
BSS that matches an entry in the disallowed list.

The new parameter can be set with the control interface SET command
using following syntax:

SET disallow_aps <disallow_list>
disallow_list ::= <ssid_spec> | <bssid_spec> | <disallow_list> | “”
SSID_SPEC ::= ssid <SSID_HEX>
BSSID_SPEC ::= bssid <BSSID_HEX>

For example:
wpa_cli set disallow_list "ssid 74657374 bssid 001122334455 ssid 68656c6c6f"
wpa_cli set disallow_list
(the empty value removes all entries)

removing the network only after having completed the operations that
