If the driver indicates the association (or authentication) was
rejected, wpa_supplicant should handle this connection failure similarly
to other cases. Previously, this was only handled with drivers that use
wpa_supplicant SME.
In case of cfg80211-based drivers, a rejected association was actually
already handled since cfg80211 generates a deauthentication event after
indicating connection failure. However, rejected authentication resulted
in wpa_supplicant waiting for authentication timeout to expire which is
unnecessary long wait.
Fix this by calling wpas_connection_failed() to use the common mechanism
to reschedule a new connection attempt with the previously attempted
BSSID blacklisted.

If WPS Registrar tries to provision a WPA/WPA2-Personal network without

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".

If the driver rejects the scan request while handling an external

Commit 0d30cc240f forced
wpa_s->current_ssid to be cleared in wpa_supplicant_mark_disassoc()

P2P group idle mechanism for the case where p2p_group_idle is not set

timeout in that case if the interface is not recognized as a client
interface (which was based on wpa_s->current_ssid being set).
Fix this by making wpas_p2p_is_client() default to client case if
wpa_s->current_ssid is NULL. This is much more likely case since the P2P
GO mode operation would not really clear the pointer without explicit

P2P includes two use cases where one of the devices is going to start a
group and likely change channels immediately after processing a frame.
This operation may be fast enough to make the device leave the current
channel before the peer has completed layer 2 retransmission of the
frame in case the ctrl::ack frame was lost. This can result in the peer
not getting TX status success notification.
For GO Negotiation Confirm frame, p2p_go_neg_conf_cb() has a workaround
that ignores the TX status failure and will continue with the group
formation with the assumption that the peer actually received the frame
even though we did not receive ctrl::ack. For Invitation Response frame
to re-invoke a persistent group, no such workaround is used in
p2p_invitation_resp_cb(). Consequently, TX status failure due to lost
ctrl::ack frame results in one of the peers not starting the group.
Increase the likelihood of layer 2 retransmission getting acknowledged
and ctrl::ack being received by waiting a short duration after having
processed the GO Negotiation Confirm and Invitation Response frames for
the re-invocation case. For the former, use 20 ms wait since this case
has been worked around in deployed devices. For the latter, use 50 ms
wait to get even higher likelihood of getting ctrl::ack through since
deployed devices (and the current wpa_supplicant implementation) do not
have a workaround to ignore TX status failure.
20 ms is long enough to include at least couple of retries and that
should increase likelihood of getting ctrl::ack through quite a bit. The
longer 50 ms wait is likely to include full set of layer 2 retries.

By default, P2P is enabled globally for all virtual interfaces and this
makes wpa_supplicant include WSC and P2P IEs in Probe Request frames for

operations, it is now possible to disable addition of WSC and P2P IEs
into Probe Request frames with a per-interface p2p_disabled parameter.
This can be set either in the configuration file (p2p_disabled=1) or at
run time ("wpa_cli -i wlan0 set p2p_disabled 1"). Unlike the previous

Setting just ssid->passphrase is not enough to complete the network

This EAP type uses a vendor specific expanded EAP header to encapsulate
EAP-TLS with a configuration where the EAP server does not authenticate
the EAP peer. In other words, this method includes only server
authentication. The peer is configured with only the ca_cert parameter
(similarly to other TLS-based EAP methods). This method can be used for
cases where the network provides free access to anyone, but use of RSN

This enables setting a different max inactivity timeout for P2P GO.
This timeout is used to detect inactive clients. In some scenarios
it may be useful to have control over this and set a shorter timeout
than the default 300s. For example when running STA and P2P GO interfaces
concurrently, the STA interface may perform scans which may cause the
GO to miss a disassoc / deauth frames from a client and keep assuming
that the client is connected until the inactivity detection kicks in.

Like bgscan, autoscan is an optional module based feature to automate
scanning but while disconnected or inactive.
Instead of requesting directly a scan, it only sets the scan_interval
and the sched_scan_interval. So, if the driver supports sched_scan,
autoscan will be able to tweak its interval. Otherwise, the tweaked
scan_interval will be used. If scan parameters needs to be tweaked, an
autoscan_params pointer in wpa_s will provide those. So req_scan /
req_sched_scan will not set the scan parameters as they usually do, but
instead will use this pointer.
Modules will not have to request a scan directly, like bgscan does.
Instead, it will need to return the interval it wants after each
notification.

Some of the authentication/association failure paths left wpa_state to
its previous value. This can result in unexpected behavior when
wpa_supplicant tries to find an AP to connect to since the uncleared
state can result the in the selected BSS being ignored if it is same as
the previously used BSS. This could happen, e.g., when wpa_supplicant
SME was used and the AP rejected authentication. Fix this by explicitly
setting state to DISCONNECTED on auth/assoc failures that did not yet do
this.

If multiple station mode radios are bridged together on the same device,

This can results in problems since multiple instances of supplicant side

problem by filtering bridge interface EAPOL RX based on the desctination

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.

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.
Driver global init was considered a hard failure. Thus if, for example,
you used the Broadcom STA driver and didn't have nl80211 or cfg80211

the nl80211 driver's global init would fail with the following message:
nl80211: 'nl80211' generic netlink not found

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.

This avoids allocating global driver state for driver wrappers that
are built in but not used. This can save some resources and avoids
failures with driver_nl80211.c that is now initializing netlink
connections for nl80211 in global_init().
This code was used only with driver_test.c to allow MLME operations
in hostapd to be tested without having to use a real radio. There
are no plans on extending this to any other use than testing and
mac80211_hwsim has now obsoled the need for this type of testing.
As such, we can drop this code from wpa_supplicant to clean up the
implementation of unnecessary complexity.
This command allows an external program manage the BSS blacklist

This is the first step in allowing SA Query mechanism in hostapd to be
used with drivers that implement authentication and association MLME/SME
(i.e., do not use ieee802_11.c).
New configuration parameters home_imsi and home_milenage can be used
to configure SIM/USIM simulator parameters for network selection based
on SIM/USIM credentials.
home_imsi=(MCC | MNC | '-' | rest of IMSI)
home_milenage=(Ki):(OPc):(SQN)
For example:
home_imsi=310026-000000000
home_milenage=90dca4eda45b53cf0f12d7c9c3bc6a89:cb9cccc4b9258e6dca4760379fb82581:000000000123
Add support for network selection for username/password credentials with
EAP-TTLS and EAP-PEAP. The new global configuration parameters
home_username, home_password, and home_ca_cert can be used to specify
credentials for network selection.
This adds the basic mechanism for running through network selection:
scan, ANQP fetch, network selection, and connection. Actual rules for
network selection and the creation of the network block are still
missing, but will be added in separate commits.
Add mechanism for using GAS/ANQP to query Interworking related
information from APs. The received information is stored in the BSS
table and can be viewed with ctrl_iface BSS command.
New ctrl_iface command ANQP_GET can be used to fetch ANQP elements from
a specific AP. Additional commands FETCH_ANQP and STOP_FETCH_ANQP can be
used to initiate and stop an iteration through all APs in the BSS table
that indicate support Interworking to fetch ANQP elements from them.
"hostapd_cli ess_disassoc (STA addr) (URL)" can now be used to send
an ESS Dissassociation Imminent notification to the STA. This event
is shown in wpa_supplicant ctrl_iface monitors (e.g., wpa_cli):
"WNM: ESS Disassociation Imminent - session_info_url=http://example.com/session/"
The new wpa_supplicant.conf file global parameters interworking and
hessid can be used to configure wpa_supplicant to include
Interworking element in Probe Request frames.
EVENT_WPS_BUTTON_PUSHED wpa_supplicant_event can now be used in
station mode driver_*.c to indicate that a push button has been
pushed. This will activate WPS PBC mode.
When initializing, the scheduled scan code was being called before
everything is ready. With normal scans, the first scan round is
delayed, so the initialization is finished by the time it really

this function instead of starting the scheduled scan directly during

Clear the P2P GO callback parameters when removing the group to avoid
using these for non-P2P AP mode.
This is a fix for the bug I found in the following scenario:
A) p2p_group_add
A) p2p_group_remove wlan0
A) add_n
A) set_n 0 ssid "testap"
A) set_n 0 key_mgmt NONE
A) set_n 0 mode 2
A) set_n 0 frequency 2412
A) enable_n 0
B) try connect to testap
Authentication request will be always rejected because of
HOSTAPD_ACL_REJECT and not cleaned callbacks when group removed.
This allows the AP to be selected based on the BSSID when WPA-PSK
is used with a passphrase. The PSK will be derived from the passphrase
after the SSID has been learned from scan results.
This implements GAS request mechanism that is aimed at being used to
replace use case specific GAS/ANQP implementations in the future.
Compared to the earlier implementation in P2P SD, this implementation
includes support for multiple concurrent requests and more thorough
validation of frames against the pending query data.
GAS header processing, including comeback and reassembly, are handled
within gas_query.c and the users of this module will only need to
provide the Query Request and process the (possibly reassembled)
Query Response.
GAS/ANQP is a generic protocol and in no way specific to P2P, so move
routines used to build GAS/ANQP frames to a separate file that can be
shared for other uses than just P2P service discovery.
The new function, p2p_scan_ie_buf_len(), can be used to figure out
how large a buffer needs to be allocated for p2p_scan_ie() use. This
makes it easier to add new data into the buffer without forcing all
callers to be updated to use a larger buffer.
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).
If the initial attempt to start a scan for p2p_find fails, an error
is reported. However, the P2P scan handler and search state was
left behind. That can result in unexpected behavior when the next
non-P2P scan results are indicated. Avoid this by clearing the
P2P search state on failure.
There is no need to request periodic bgscans when the driver claims
to have capability for roaming within ESS. Ignoring the bgscan
configuration allows the same configuration file to be used both
with drivers the handle roaming and with drivers that don't.
If the driver indicates that it supports BSS selection (including
roaming within an ESS) with WPA_DRIVER_FLAGS_BSS_SELECTION, modify
ap_scan=1 mode to behave like ap_scan=2 mode for BSS selection.
The initial scan is still done to avoid the need for strict
configuration of or security parameters (e.g., to figure out whether
TKIP or CCMP is being used as the group cipher). However, when
requesting the driver to connect, the bssid and freq parameters are
not provided to leave the driver in control of selecting which BSS
to use and to allow the driver to decide when to roam.
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.
wpa_supplicant returns the PIN in reply to the connect method. Treating
this value as an integer runs the risk of not returning the correct
value if the first digit(s) happens to be a zero(es). To return the
correct PIN it needs to be returned as a string.

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.

The P2P specification (3.1.4.3) disallows use of the Label configuration
method between two P2P devices. This was previously enforced at upper
level, but the obsolete code can be removed from wpa_supplicant. This
adds a bit more strict enforcement of the policy, but should not result
in practical differences since no known P2P implementation uses Label
config method.
If a network configuration block is removed or modified, flush
all PMKSA cache entries that were created using that network
configuration. Similarly, invalidate EAP state (fast re-auth).
The special case for OKC on wpa_supplicant reconfiguration
(network_ctx pointer change) is now addressed as part of the
PMKSA cache flushing, so it does not need a separate mechanism
for clearing the network_ctx values in the PMKSA cache.
The previous code was trying to figure out which WPA version is
used based on the extra IEs requested for Association Request. That
did not work properly in cases where non-WPA networks are used with
some extra IEs. Fix this by using more robust mechanism for passing
the WPA versions from core wpa_supplicant to the driver_ops
associate().
Instead of hardcoding the Config Methods attribute value in Probe
Request frames, set this based on the configured parameter
config_methods to allow correct set of methods to be advertised.
This change is a first step in better supporting different driver
architectures for AP mode operations with nl80211. This commit in
itself does not add new functionality, but it makes it easier to add
new AP mode parameters to address needs of drivers that have more of
the MLME/SME in firmware or kernel.
Various pieces of the P2P code assume that P2P is enabled, so make
the D-Bus code not call the P2P stuff if P2P is disabled. Also
ensures that if P2P is disabled a suitable error is returned to

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.

This makes sure that the old connection is not maintained if the new
configuration does not allow it anymore. In addition, it is better to
use wpa_supplicant_clear_connection() instead of just clearing
wpa_s->current_ssid here to keep things in sync.
When the BSS table size limit has been reached, drop first the oldest
BSS entries for which there is not a matching network in the
configuration based on SSID (wildcards are ignored). This makes it
less likely to hit connection issues in environments with huge number
of visible APs.
Only accept Probe Request frames that have a Wildcard BSSID and a
destination address that matches with our P2P Device Address or is the
broadcast address per P2P specification 3.1.2.1.1.
The current implementation of p2p_intra_bss doesn't work since the flag
