ab28911dbf P2P: Deinitialize global P2P context on P2P mgmt interface removal
The P2P implementation assumes that the first wpa_s interface instance
is used to manage P2P operations and the P2P module maintains a pointer
to this interface in msg_ctx. This can result in issues (e.g., use of
freed memory) when the management interface is removed. Fix this by
deinitializing global P2P data if the interface that created it is
removed. This will disable P2P until the next interface is added.

aa9bb7644b P2P: Allow older scan results to improve p2p_connect-auto robustness
Previusly the peer was assumed to not be operating a GO if the BSS entry
for it was not updated in the single scan run started by
p2p_connect-auto. This is not very robust since a scan may miss the peer
if either a Probe Request or Probe Response frame is lost. Improve
robustness by assuming the peer is still operating the GO and starting
the join operation. If the GO is not found during PD-for-join or the
single-channel scans during the join, fall back to GO Negotiation.

fea7c3a055 Ignore network blocks that have invalid WEP key length
Do not try to associate with a network that has an invalid or incomplete
configuration because the association or at least data connection would
fail anyway. This commits adds a common function for checking whether a
network block is disabled to make it easier to check network blocks
without having to reject them during configuration file parsing (which
would prevent wpa_supplicant from starting). The only additional check
added in this commit is to verify the WEP key length. Similar checks for
other parameters can be added in future commits.

c3701c66a5 Add handling of OBSS scan requests and 20/40 BSS coex reports
Add support for HT STA to report 40 MHz intolerance to the associated AP.
A HT station generates a report (20/40 BSS coexistence) of channel list
if it finds a non-HT capable AP or a HT AP which prohibits 40 MHz

from the scan results.

Parse the OBSS scan parameter from Beacon or Probe Response frames and
schedule periodic scan to generate 20/40 coexistence channel report if
requested to do so. This patch decodes Scan Interval alone from the OBSS
Scan Parameters element and triggers scan on timeout.

wpa_drv_scan() may fail for the initial p2p_connect join scan request,
e.g., if the driver happened to be scanning at the time the new

result in partial scan results (e.g., from p2p_find social scan) from
being used as full results for join (or now more importantly for
p2p_connect auto) purposes. Fix this by registering the new scan result
handler only if wpa_drv_scan() returns success.

eb6f8c2bd4 P2P: Fix crash for failure case when WSC PIN is entered incorrectly
When forming a P2P group using WSC PIN method, if the PIN is entered
incorrectly the P2P client supplicant instance will crash as a result
of cleanup happening on data that is still in use in a case where a
separate P2P group interface is used.

For example, here is the path for the first crash:
eap_wsc_process():
- creates struct wpabuf tmpbuf; on the stack
- sets data->in_buf = &tmpbuf;
- calls wps_process_msg()
- which calls wps_process_wsc_msg()
- which, in case WPS_M4: calls wps_fail_event()
- which calls wps->event_cb()
- wps->event_cb = wpa_supplicant_wps_event()
- wpa_supplicant_wps_event()
- wpa_supplicant_wps_event_fail()
- which calls wpas_clear_wps()
- which calls wpas_notify_network_removed()
- which calls wpas_p2p_network_removed()
- which calls wpas_p2p_group_formation_timeout()
- which calls wpas_group_formation_completed()
- which calls wpas_p2p_group_delete()
- which calls wpa_supplicant_remove_iface()
- which calls wpa_supplicant_deinit_iface()
- which calls wpa_supplicant_cleanup()
- which calls eapol_sm_deinit()
- ... which eventually uses the ptr data->in_buf to free tmpbuf, our
stack variable and then the supplicant crashes

If you fix this crash, you'll hit another. Fix it and then a segfault.
The way we're cleaning up and deleting data from under ourselves here
just isn't safe, so make the teardown portion of this async.

c772ef43f6 P2P: Update BSS entries in P2P group interface only if P2P IE is present
For concurrency scenarios we should not update the scan results without
P2P IE to P2P group interfaces. This patch is to take care if a scan has
been requested on STA interface and scan results are getting updated
from sibling to P2P group interface. A P2P GO Probe Response for a
legacy STA scan would be without P2P IE. So it will wrongly update the
BSS list of P2P group interface too when results are updated from
sibling.

Since P2P group interfaces are used only for connecting to a P2P group,
it is fine to filter out all non-P2P entries from their BSS table.

For debugging I needed to look at the frames in a wpa_supplicant debug

2d43d37ff2 DBus: Add ability to report probe requests
Some applications require knowing about probe requests to identify
devices. This can be the case in AP mode to see the devices before they
connect, or even in P2P mode when operating as a P2P device to identify
non-P2P peers (P2P peers are identified via PeerFound signals).

As there are typically a lot of probe requests, require that an
interested application subscribes to this signal so the bus isn't always
flooded with these notifications. The notifications in DBus are then
unicast only to that application.

A small test script is also included.

baf513d695 Pass signal strength through, fix units
The signal strength is currently never used as the only driver reporting
it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never
populated by the kernel. The kernel will (soon) populate
IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that.

Also, since it was never really populated, we can redefine the signal
field to be in dBm units only.

My next patch will also require knowing the signal strength of probe
requests throughout the code (where available), so add it to the

If multiple station mode radios are bridged together on the same device,
it is possible for wpa_supplicant to receive EAPOL frames from the

This can results in problems since multiple instances of supplicant side
could end up trying to process a single 4-way handshake. Avoid this
problem by filtering bridge interface EAPOL RX based on the desctination
MAC address. It should be noted that this works only when unicast

group address (e.g., most wired networks).

First, 3f6e50ac28 changed the type used to

addition to the type change the way in which the vendor extension data
was provided to the function creating the string was incorrect and would
not present the correct vendor extension data even in string format.

Revert the type change made in 3f6e50ac28
and present the WPS vendor extension data as an array of an array of
bytes as it was before.

Second, 3f6e50ac28 changes the secondary
device types representation from an array of an array of bytes to an
array of bytes. Revert that change to make secondary device types
accessible via an array of an array of bytes again.

a7a30b90e5 P2P: Fix group idle timer cancellation on group removal
The wpas_p2p_group_idle_timeout was getting cancelled in the beginning
of wpas_p2p_group_delete(). However, in the case of P2P client role,
this function called wpa_supplicant_deauthenticate() next and that ended
up changing state to WPA_DISCONNECTED which resulted in
wpas_p2p_notif_disconnected() rescheduling the timeout. This left the
unexpected timeout behind after the group was removed. If another group
operation was started within P2P_MAX_CLIENT_IDLE (10) seconds, that
timeout could end up terminating the group while it was still being set
up.

Fix this by reordering wpas_p2p_group_delete() to cancel the group idle
timeout only after having called wpa_supplicant_deauthenticate(). The
group idle timeout is still rescheduled, but it gets removed immediately
afterwards when the actual group information is being cleared.

The previous elements need to be moved only if we are inserting the new

the end of the array does not cause real problems, some static analyzers
complain about this, so in addition to slightly optimized

87343c2017 bgscan_simple: Refinements to fast-scan backoff
These changes account for situations where the CQM threshold
might be approximately the same as the currently received signal,
and thus CQM events are triggered often due to measurement
error/small fluctuations.  This results in scanning occurring
too frequently.

Firstly, inhibit the immediate scan when the short-scan count
is at the maximum.  This keeps bursts of CQM toggling from
causing a torrent of back-to-back scans.  This does not inhibit
immediate scans if the CQM triggers a second time (if the signal
falls lower past the hysteresis).  This reduces the scan rate in
the worst case (fast-rate toggling high/low CQM events) to the
short scan interval.

Secondly, change the behavior of the short scan count so it acts like
a "leaky bucket".  As we perform short-scans, the bucket fills until
it reaches a maximal short-scan count, at which we back-off and
revert to a long scan interval.  The short scan count decreases by
one (emptying the bucket) every time we complete a long scan interval
without a low-RSSI CQM event.

This reduces the impact of medium-rate toggling of high/low CQM
events, reducing the number of short-interval scans that occur before
returning to a long-interval if the system was recently doing
short scans.

cd2f4ddfb9 Update WPA/RSN IE properly for driver based BSS selection
This patch fixes an issue with roaming for drivers that set
WPA_DRIVER_FLAGS_BSS_SELECTION (currently ath6kl). On moving to an AP
with a different BSSID, an EVENT_ASSOC is received and the subsequent
4-way handshake may fail because of a mismatch between the RSN IE in
message 3/4 and in Beacon/Probe Response. This happens only when the APs
use different RSN IE contents and ap_scan is set to 1, since
wpa_supplicant fails to update its cached IEs.

Initial association may fail, too, in case of multiple APs with
the same SSID, since BSSID selection is done by the driver and again
a mismatch could be seen.

Fix these two issues by clearing and updating the cached IEs on
receiving an Association event from the driver. Also, retrieve the
scan results when the new BSS information is not present locally.

3d9975d5b0 Do not trigger fast reconnection on locally generated deauth/disassoc

The reason this commit broke it is that the state

Fix this by calling wpa_init_keys() when the new

ed57c5907e SME: Fix processing of Authentication request failure
The wpa_state needs to be dropped back to DISCONNECTED to allow scan
results to trigger a new authentication attempt. In addition, we can use
wpas_connection_failed() instead of requesting a scan after a fixed time
to make this error case more consistent with other similar error paths
in sme.c.

I have a test case where I remove and insert another network adapter
between two connections to AP. The interface get the same interface name
but switches macadresses between the connections. When running WPA2 I
got a failure in EAPOL negotiation and found out that the reason for
this was that the supplicant did not update the MAC address in the
correct place.

WPS to be used with WPA/TKIP-only configuration (i.e., at minimum, mixed

56d24b4ee0 Call wpas_connection_failed() only if actually trying to connect
A disconnection event from the driver may end up getting delivered at a
time when wpa_supplicant is not even trying to connect (e.g., during a
scan that was already started after WPS provisioning step). In such a
case, there is not much point calling wpas_connection_failed() and
skipping this avoids confusing attempts of re-starting scanning while
the previous scan is still in progress.

treated as full signal bar, signals between range of -95<->-35dBm are
displayed linearly. Convert WEXT signal level value to scale that
nl80211 typically reports in dBm. The condition which differentiates

Control requests will be extended for non-EAP uses later, so it makes
sense to have them be generic. Furthermore, having them defined as an

interfaces that may not use field names. The public ctrl_req_type /

4483f23e15 dbus: Raise PropertiesChanged on org.freedesktop.DBus.Properties
wpa_supplicant dbus objects are currently difficult to use with
GDBusProxy. This is because they do not follow the dbus standard in
emitting the PropertiesChanged signal on the standard D-Bus properties
interface, so GDBusProxy stores stale property values.

Fix this by raising PropertiesChanged on the standard interface.
For backwards compatibility, the existing custom PropertiesChanged
signals are not removed; I anticipate them being removed in a future
major release.

This patch stops any on-going "p2p_find" on creating an Autonomous GO.

So normally the GO doesn't need to do a p2p_find until and unless it
wants to invite a P2P Client. In case of Invite scenario, logically it
is better to do a explicit discover [via user intervention] after the GO
is created. This patch will help to reduce battery wastage [due to

303f60d39b P2P: Do not request station mode scans during P2P operations
The P2P search mechanism depends on the same scan functionality that
is used for station mode scans. If these operations are being used
at the same time, scan result processing is not handled properly.
Avoid unexpected behavior by delaying station mode scan requests
if a P2P operation is in progress.

Among other things, this allows the station mode connection attempt
to be continued after a P2P find or group formation has been completed
if the interface is available (i.e., when the P2P group uses a
separate virtual interface).

fd2f2d0489 Remove EAP-TTLSv1 and TLS/IA
These protocols seem to be abandoned: latest IETF drafts have expired
years ago and it does not seem likely that EAP-TTLSv1 would be
deployed. The implementation in hostapd/wpa_supplicant was not complete
and not fully tested. In addition, the TLS/IA functionality was only
available when GnuTLS was used. Since GnuTLS removed this functionality
in 3.0.0, there is no available TLS/IA implementation in the latest
version of any supported TLS library.

Remove the EAP-TTLSv1 and TLS/IA implementation to clean up unwanted
complexity from hostapd and wpa_supplicant. In addition, this removes
any potential use of the GnuTLS extra library.

af9d709019 D-Bus: Fix memory leak when using array of array of bytes
When parsing a dict entry which is an array of an array of bytes the entry
representing the dict entry has DBUS_TYPE_ARRAY as its type and
WPAS_DBUS_TYPE_ARRAY as its array_type. The function freeing this parsed
data incorrectly tested the entry type for WPAS_DBUS_TYPE_ARRAY while doing
no testing of this value for array_type. This results in a memory leak
whenever a D-Bus message with this type of data is parsed.

Messages affected are:
fi.w1.wpa_supplicant1.Interface.P2PDevice
	using RequestedDeviceTypes with Find method
	using SecondaryDeviceTypes or VendorExtension with P2PDeviceProperties

fi.w1.wpa_supplicant1.Group
	using WPSVendorExtensions with Properties property

All of the above messages are parsed with the same function,
wpa_dbus_dict_get_entry, so the assignment of the entry's type and
array_type is consistent. The parsed data is also consistently freed with
the same function, wpa_dbus_dict_entry_clear, so we can use the same checks
to free the data correctly.

6aeeb6fa21 dbus: clean up new D-Bus interface getters and setters
A number of fixes/improvements here:

1) Remove casting of getter/setter function types which allows
us to change the prototypes in the future and not have hard-to-find
runtime segfaults

2) Instead of having the getters create a fake reply message which
then gets its arguments copied into the real reply message, and is
then disposed, just pass message iters around and have them add
their arguments to the message itself

3) For setters, just pass in the message iter positioned at the
start of the argument list, instead of each setter having to skip
over the standard interface+property name

4) Convert error handling to use DBusError and return the error
back down through the call stacks to the function that will
actually send the error back to the caller, instead of having a
fake DBusMessage of type DBUS_MESSAGE_TYPE_ERROR that then
needs to have the error extracted from it.

But most of all, this fixes various segfaults (like rh #725517
and #678625) which were caused by some functions deep down in the
getter callpaths wanting a source DBusMessage* when the getters were
used for two things: signals (which don't have a source DBusMessage)
and methods (which will have a source DBusMessage that's being
replied to).  This duality made the code fragile when handling
errors like invalid IEs over the air.

Some new code we're working on will require the dbus type "aay" (an
array of arrays of bytes). To add this, refactor the array code to
reduce code duplication by given a type string to the array starting
code, and also add code to create and parse such arrays from or into an
array of struct wpabuf respectively.

Since there's no unique DBus type for this, add a "fake"
WPAS_DBUS_TYPE_BINARRAY type that is separate from the regular DBus
types for parsing.

However, this callback can be called before hostap_setup_interface()

called before the wpa_supplicant connection information was updated.
