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.

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.
This is already taken care in case of invoking a persistent GO. GO as
such will be advertising via the beacons for other devices to discover.
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
p2p_find operations] in scenarios where user creates a GO and doesn't
initiate a connection.
Once PBC overlap detected when using dynamic group interfaces, the wpa_s
corresponding to P2P group interface is freed. This patch avoids
accessing the wpa_s data structure after it is freed. This fixes a
possible crash in P2P client role in such a case.
The persistent_reconnect configuration parameter was used to decide
whether to accept invitation to re-establish a persistent group.
However, this was not being advertised in the Group Capability bitmap.

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 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

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 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

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

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

The current implementation of p2p_intra_bss doesn't work since the flag

Need to define CONFIG_NO_PBKDF2 even though the crypto cleanup moved
the function to a separate file since there is conditional code in
wpa_supplicant/config.c. In addition, wpa_passphrase should not be
built at all if passphrase functionality is removed.
These checks were previously skipped if the scan result included WPA
or RSN IE. However, that can result in selecting a network that does
not match local configuration in some cases.
There are some corner cases, where the wpa_supplicant_req_scan() call
may end up scheduling a scan even if we are about to start a GO. Avoid
this by explicitly marking the GO network to be selected for the next
connection.
Some new code we're working on will require the dbus type "aay" (an

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.

WPAS_DBUS_TYPE_BINARRAY type that is separate from the regular DBus

Processing of the scan results for RSN pre-authentication candidates

Fix this by moving the processing to happen after the network has

point, use the BSS table instead of scan results to fetch the
