1966e3d1b7 sched scan: Fix passive scanning
Scan wasn't initiated in case the config contained only networks without
scan_ssid. In such a case we want scan to be initiated without any SSIDs
to actively scan but include all the SSIDs in the filter list. Also
added some debug logs to easily see which SSIDs were included in which
list.

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.

2d4f15d683 P2P: Stop any on-going "p2p_find" on creating an Autonomous GO
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.

Avoid unexpected behavior by delaying station mode scan requests

available when GnuTLS was used. Since GnuTLS removed this functionality
in 3.0.0, there is no available TLS/IA implementation in the latest

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.

e73edcaa6a wpa_s AP mode: Fix regression in P2P AP mode setup
Commit c76e5d7f9b moved the
ap_configured_cb() call into a completion callback from AP mode code.
However, this callback can be called before hostap_setup_interface()
returns. In that case, the ap_configured_cb() ended up getting
called before the wpa_supplicant connection information was updated.
Fix this by reordering code to set up everything before calling
hostapd_setup_interface().

4378fc14eb nl80211: Send EAPOL frames as QoS data frames for QoS aware clients
This should fix EAPOL reauthentication and rekeying timeout issues
with Intel clients when using WMM (e.g., with IEEE 802.11n). These
stations do not seem to be able to handle EAPOL data frames as
non-QoS Data frames after the initial setup.

This adds STA flags to hapd_send_eapol() driver op to allow
driver_nl80211.c to mark the EAPOL frames as QoS Data frame
when injecting it through the monitor interface.

6d21d41125 bgscan_simple: Time out short scan interval
We gain diminishing returns by the short scan interval. The short
scan interval is used to hunt for a better AP if the RSSI of the
current AP drops. However, if we never roam, and the AP continues
to have low RSSI, at some point we should give up and return to
the slow background scan rate, otherwise we waste a lot of power.

bc8397822b wpa_supplicant: Search BSS list from back to front

example both <bssid, "Check11b"> (from the previous test) and <bssid,
"Check11g"> (from the current test) - note that the bssid is the same for
both. The (old) D-Bus API for fetching scan responses from wpa_supplicant
is fetch-by-bssid, so the caller (flimflam) incorrectly believes we're
associated with <bssid, "Check11b">.

This is needed to allows WPS PBC session overlap detection to work
with drivers that process Probe Request frames internally. This
code is is run in hostapd, but the wpa_supplicant AP mode did not
have call to the hostapd_probe_req_rx() function even though it
registered handlers for hostapd Probe Request RX callbacks.

d601247ca9 P2P: Allow WPS_PBC command on GO to select on P2P Device Address
An optional parameter, p2p_dev_addr, can now be given to WPS_PBC
command on P2P GO to indicate that only the P2P device with the
specified P2P Device Address is allowed to connect using PBC. If
any other device tries to use PBC, a session overlap is indicated
and the negotiation is rejected with M2D. The command format for
specifying the address is "WPS_PBC p2p_dev_addr=<address>", e.g.,
WPS_PBC p2p_dev_addr=02:03:04:05:06:07

In addition, show the PBC session overlap indication as a WPS failure
event on an AP/GO interface. This particular new case shows up as
"WPS-FAIL msg=4 config_error=12".

resulted in blacklisting not working in the expected way (i.e., the same

problems.

Use a common function to handle all these cases and fix the blacklist
operation. Use smaller delay before trying to scan again during the
initial cycle through the available APs to speed up connection. Add

By default, make hostapd and wpa_supplicant maintain an internal

- Probe Request frames (timing, RSSI)
- Association events (timing)
- SNonce from Supplicants

- Scan results (timing, signal/noise)
- Association events (timing)

The internal pool is used to augment the random numbers generated
with the OS mechanism (os_get_random()). While the internal
implementation is not expected to be very strong due to limited
amount of generic (non-platform specific) information to feed the
pool, this may strengthen key derivation on some devices that are
not configured to provide strong random numbers through
os_get_random() (e.g., /dev/urandom on Linux/BSD).

This new mechanism is not supposed to replace proper OS provided
random number generation mechanism. The OS mechanism needs to be
initialized properly (e.g., hw random number generator,
maintaining entropy pool over reboots, etc.) for any of the
security assumptions to hold.

If the os_get_random() is known to provide strong ramdom data (e.g., on
Linux/BSD, the board in question is known to have reliable source of
random data from /dev/urandom), the internal hostapd random pool can be
disabled. This will save some in binary size and CPU use. However, this
should only be considered for builds that are known to be used on
devices that meet the requirements described above. The internal pool
is disabled by adding CONFIG_NO_RANDOM_POOL=y to the .config file.

9dd7d6b09c WPS: Add special AP Setup Locked mode to allow read only ER
ap_setup_locked=2 can now be used to enable a special mode where
WPS ER can learn the current AP settings, but cannot change then.
In other words, the protocol is allowed to continue past M2, but
is stopped at M7 when AP is in this mode. WPS IE does not
advertise AP Setup Locked in this case to avoid interoperability
issues.

In wpa_supplicant, use ap_setup_locked=2 by default. Since the AP PIN
is disabled by default, this does not enable any new functionality
automatically. To allow the read-only ER to go through the protocol,
wps_ap_pin command needs to be used to enable the AP PIN.

43882f1efc Allow TSN AP to be selected when configured for WEP
Commit d8d940b746 introduced a regression
that prevented TSN APs from being used with WEP since the AP was
rejected if it advertised WPA or RSN IE when we were configured to use
WEP. Resolve this by checking whether the AP is advertising a TSN, i.e.,
whether the AP allows WEP to be used as a group cipher. If so, allow
the AP to be selected if we are configured to use static WEP or
IEEE 802.1X (non-WPA).

It should be noted that this is still somewhat more restricted in AP
selection than earlier wpa_supplicant branches (0.7.x or older) that
ignore the WPA/RSN IE completely when configured for non-WPA.

8ee69e0633 dbus_new_handlers: Don't send NULL to dbus_message_new_error
The new DBus API helper function wpas_dbus_error_unknown_error
function can be called as a result of a failure within internal
getter calls, which will call this function with a NULL message
parameter.  However, dbus_message_new_error looks very unkindly
(i.e, abort()) on a NULL message, so in this case, we should not
call it.

I've observed this course of events during a call to
wpas_dbus_getter_bss_wpa with a faileld parse of the IE parameter.
We got here through a call to fill_dict_with_properties which
explicitly calls getters with a NULL message parameter.  Judging
from the way it is called, this could easily occur if an AP sends
out a malformed (or mis-received) probe response.  I usually run
into this problem while driving through San Francisco, so I'm
exposed to any number of base stations along this path.

556522ee09 dbus: Treat '' in SSIDs of Interface.Scan as a request for broadcast scan
This patch changes wpa_supplicant policy for handling '' in SSIDs field of
Interface.SSID DBus message. It treats '' (zero-length) SSID as a request
for a broadcast scan, instead of ignoring it.

This patch updates DBus API .Scan() logic per the test cases listed below:

1) Interface.Scan({'Type':'active', 'Channel':(2412, 20)})
   Request:     Active scan with only '' SSID (1 channel)
   Should be:   1 broadcast ProbeRequest on specified channel
   Previous:    1 broadcast ProbeRequest on specified channel
   This Patch:  1 broadcast ProbeRequest on specified channel

2) Interface.Scan({'Type':'active', 'Channel':(2412, 20), 'SSIDs':['']})
   Request:     Active scan with only '' SSID (1 channel)
   Should be:   1 broadcast ProbeRequest on specified channel
   Previous:    No ProbeRequests; passive scan results for specified channel
   This Patch:  FIXED: 1 broadcast ProbeRequest on specified channel

3) Interface.Scan({'Type':'active', 'Channel':(2412, 20), 'SSIDs':['MySSID']})
   Request:     Active scan with only non-'' SSIDs (1 channel)
   Should be:   1 directed ProbeRequest for each SSID on specified channel,
	no broadcast ProbeRequest
   Previous:    1 directed ProbeRequest for each SSID on specified channel,
	no broadcast ProbeRequest
   This Patch:  1 directed ProbeRequest for each SSID on specified channel,
	no broadcast ProbeRequest

4) Interface.Scan({'Type':'active', 'Channel':(2412, 20), 'SSIDs':['',
	'MySSID']})
   Request:     Active scan with SSIDs, including 1 '' SSID (1 channel)
   Should be:   1 broadcast ProbeRequest, 1 directed ProbeRequest for each
	non-'' SSID on specified channel
   Previous:    1 directed ProbeRequest for each non-'' SSID on specified
	channel
   This Patch:  FIXED: 1 broadcast ProbeRequest, 1 directed ProbeRequest for
	each non-'' SSID on specified channel

a7af023b84 dbus: Fix passive/active scans in some cases
Currently the DBus Interface.Scan API is counter-intuitive. It issues
ProbeRequests when doing passive scans when channels are specified, and
does not issue ProbeRequests for broadcast active scans.

This patch updates DBus API .Scan() logic per the test cases listed below:

 1) Interface.Scan({'Type':'passive'})
    Request:     Passive scan (all channels)
    Should be:   No ProbeRequests; Passive Scan results for all channels
    Previous:    1 ProbeRequest on all channels for both broadcast SSID and
	selected network (scan_ssid=1)
    This Patch:  --No change--: 1 ProbeRequest on all channels for both
	broadcast SSID and selected network (scan_ssid=1)

 2) Interface.Scan({'Type':'passive', 'Channel':(2412, 20)})
    Request:     Passive scan (1 channel)
    Should be:   No ProbeRequests; Passive Scan results for 1 channel
	(plus overlapping channels)
    Previous:    1 broadcast ProbeRequest on specified channel
    This Patch:  --Fixed--: No ProbeRequests; Passive Scan results for 1
	channel (plus overlapping channels)

 3) Interface.Scan({'Type':'active'})
    Request:     Active scan with no SSIDs (all channels)
    Should be:   1 broadcast ProbeRequest on all channels
    Previous:    No ProbeRequests;  passive scan results for all channels
    This Patch:  --Fixed--: 1 broadcast ProbeRequest on all channels

 4) Interface.Scan({'Type':'active', 'Channel':(2412, 20)})
    Request:     Active scan with no SSIDs (1 channel)
    Should be:   1 broadcast ProbeRequest on specified channel
    Previous:    No ProbeRequests; Passive scan results for specified
	channel (plus overlapping channels)
    This Patch:  --Fixed--: 1 broadcast ProbeRequest on specified channel

b4e34f2fdf WPS: Make testing operations configurable at runtime
Instead of build time options (CONFIG_WPS_TESTING_EXTRA_CRED and
CONFIG_WPS_EXTENSIBILITY_TESTING), use a single build option
(CONFIG_WPS_TESTING) and runtime configuration of which testing
operations are enabled. This allows a single binary to be used
for various tests.

The runtime configuration can be done through control interface
with wpa_cli/hostapd_cli commands:
Enable extensibility tests:
set wps_version_number 0x57
Disable extensibility tests (WPS2 build):
set wps_version_number 0x20
Enable extra credential tests:

The wpa_state change can happen before the D-Bus interface is set up,

it should be possible to reorder initialization code to make sure

00468b4650 Add TLS client events, server probing, and srv cert matching
This allows external programs (e.g., UI) to get more information
about server certificate chain used during TLS handshake. This can
be used both to automatically probe the authentication server to
figure out most likely network configuration and to get information
about reasons for failed authentications.

The follow new control interface events are used for this:
CTRL-EVENT-EAP-PEER-CERT
CTRL-EVENT-EAP-TLS-CERT-ERROR

In addition, there is now an option for matching the server certificate
instead of the full certificate chain for cases where a trusted CA is
not configured or even known. This can be used, e.g., by first probing
the network and learning the server certificate hash based on the new
events and then adding a network configuration with the server
certificate hash after user have accepted it. Future connections will
then be allowed as long as the same server certificate is used.

Authentication server probing can be done, e.g., with following
configuration options:
    eap=TTLS PEAP TLS
    identity=""
    ca_cert="probe://"

Example set of control events for this:
CTRL-EVENT-EAP-STARTED EAP authentication started
CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=21
CTRL-EVENT-EAP-METHOD EAP vendor 0 method 21 (TTLS) selected
CTRL-EVENT-EAP-PEER-CERT depth=0 subject='/C=US/ST=California/L=San Francisco/CN=Server/emailAddress=server@kir.nu' hash=5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a
CTRL-EVENT-EAP-TLS-CERT-ERROR reason=8 depth=0 subject='/C=US/ST=California/L=San Francisco/CN=Server/emailAddress=server@kir.nu' err='Server certificate chain probe'
CTRL-EVENT-EAP-FAILURE EAP authentication failed

Server certificate matching is configured with ca_cert, e.g.:
    ca_cert="hash://server/sha256/5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a"

TLS libraries (including internal implementation) may be added in
the future.

48563d86b2 Try to avoid some unnecessary roaming
When multiple APs are present in scan results with similar signal
strength, wpa_supplicant may end up bounching between them frequently
whenever new scan results are available (e.g., due to periodic scans
requested by NetworkManager). This can result in unnecessary roaming
and in case of the current cfg80211 version, to frequent network
disconnections.

Do not request a roam if the current BSS is still present in the scan
results and the selected BSS is in the same ESS and has only a slighly
stronger signal strength.

Aggregated PropertiesChanged signal is sent
- for all object after responding on DBus call
- for specified object after manual call to
  wpa_dbus_flush_object_changed_properties() function
- for each object separately after short timeout (currently 5 ms)
  which starts when first property in object is marked changed

27f43d8de5 dbus: Replace StateChanged with PropertiesChanged signal
The actual supplicant state is exposed via a property on the interface
object. So having a separate signal StateChanged for notifying about
changes is a bad idea. The standard PropertiesChanged signal should be
used for this.

The advantage of StateChanged signal was that it includes the previous
state, but not even NetworkManager is making use of this. And tracking
the old state via the property and this signal is easily possible anyway.

something to WPA internal code, just use simple strings. Possible

those throughout without having to allocate memory and copy all the
