At least with driver_test.c, the BSS table may not include frequency
information. In such a case, we need to skip rate set matching during
BSS selection to avoid rejecting valid AP.

The interface may not yet have been set to P2P client mode immediately
after GO Negotiation when doing the scan before association request.
Consequently, the scan request in this state has to specify that the
specific P2P probe mode is used to disable IEEE 802.11b rates.
Signed-hostap: Jouni Malinen <j@w1.fi>
Instead of hardcoding IEEE 802.11b rates to be disabled whenever
P2P support is built in and supported by the driver, do this only
when an interface is set to P2P mode (both when adding a new
interface and when changing the interface mode). This re-enables
use of IEEE 802.11b APs with CONFIG_P2P=y builds.
Signed-hostap: Jouni Malinen <j@w1.fi>
This function was used unconditionally if wpa_supplicant build
includes CONFIG_P2P=y. Adding a separate driver_ops for such use
is not really useful since the driver wrappers can do the same
internally. Remove this driver_ops and move matching functionality
into driver_nl80211.c which was the only driver wrapper using
this driver_ops callback.

nl80211_disable_11b_rates() function was supposed to use the 'disabled'
parameter to figure out whether to disable or re-enable 802.11b rates.
In addition, the driver deinit path was now ending up re-disabling the
enabled rates at the end of the deinit operations when the interface
type was forced back to station. Both of these issues are now fixed
and the 2.4 GHz band TX rate index is cleared properly when
wpa_supplicant is stopped.

disable_11b_rates() is called on interface addition,
but not on interface type change, resulting in 11b rates
enabled on p2p interfaces.

This can be used to apply the no-CCK rule conditionally depending on
which frame is being sent. The no-CCK rule applies only for P2P
management frames while SA Query and FT use cases do not have similar
restrictions.
Signed-hostap: Jouni Malinen <j@w1.fi>
Add a new attribute to specify whether to use CCK rate or not during
scan and sending management frames. This helps to send P2P probes
at non-CCK rate. This ensures that P2P probe request/response/action
frames are always sent at non-CCK rates.

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 was included in the AP configuration parameters, but there has
been no way to set it to anything else than the default automatic

The MS-CHAPv1 and MS-CHAPv2 RFCs specify that the password is a string
of "Unicode characters", which for Windows means UCS-2; thus the
password could be any even-length string of up to 512 bytes.
Instead of making the incompatible change of requiring the incoming
password to be UCS-2 encoded, assume the password is UTF-8 encoded and
convert it before using it in NtPasswordHash and
EncryptPwBlockWithPasswordHash.

P2P Client did not show correct frequency in the control interface
event P2P_EVENT_GROUP_STARTED. Fix that by using the frequency from
the BSS table or association event.
The netlink event processing is delayed since they are only returned
after control returns to eloop. This can result in netlink down events
being processed at a point when the interface has is actually still
there (the first event on new interface is down) and that can result in
odd behavior especially when the resulting interface-disabled event is
delivered to AP mode interface with wpa_supplicant.
Work around this by filtering netlink down events if the matching
interface is up at the time the netlink event is processed. This fixes
an issue brought up by commit 36d84860bb.
hostapd_wpa_auth_conf() is called on uninitialized memory and the
conditional blocks in this function may leave some fields into
uninitialized state. This can result in unexpected behavior elsewhere
since some of the variables may be used without matching #ifdef
blocks. Fix this by zeroing the memory.
TPK will be needed to be able to generate FTIE MIC for the
teardown message, so maintain peer data for a bit longer in
case the teardown FTIE request comes back from the driver.
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.
These can be useful in tests involving association state mismatch
between the AP and the STA (i.e., STA assumes it is still associated
but the AP does not have association state). In such a case, the AP
would be sending out unprotected Deauthentication or Disassociation
frames with reason code 6 or 7 depending on what frame is triggering
this.
The Query Response Length Limit is not allowed to be zero when
this is sent by the AP. Use 0x7F to indicate that the limit is
based on maximum number of GAS fragments.
For P2P, the p2p_connect takes in device address argument to make a
connection. However the connected event AP-STA-CONNECTED comes with
interface address. The application listening on events would find it
difficult to map interface address to the p2p device address which is
provided for connection.
Append P2P Device Address to AP-STA-CONNECTED event for P2P Client
connection. This will help applications to easily map the P2P Interface
Address to P2P Device Address on CONNECTED event. For non-P2P case, it
will just print the usual STA MAC address alone.

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.

However, this was not being advertised in the Group Capability bitmap.
