Flávio Ceolin 3f6e50ac28 dbus: Make the P2P peer's properties accessible separately
Since there is the method org.freedesktop.DBus.Properties.GetAll that
returns all properties from a specific interface, it makes more sense to
separate the properties to make it possible to get only a single
property using the method org.freedesktop.DBus.Properties.Get as well.

Jouni Malinen f63b854215 P2P: Wait for PD-before-join response
Even though the Provision Discovery Response frame from PD-before-join
does not really provide any additional information, it can be better to
wait for it before starting the join operation. This adds a minimal
extra latency in the most common case and cleans up the sequence of
driver operations and debug log by avoiding potential processing of the
Provision Discovery Response while already running a scan for the actual
connection.

If transmission of Provision Discovery Request fails, join operation is
started without the additional wait. In addition, a new timeout is used
to start the join if Provision Discovery Response is lost for any
reason.

Jouni Malinen c19316354e P2P: Skip event notification on PD Response in join-group case
Provision Discovery is used as a notification to the GO in the case we
are about join a running group. In such case, there is not much point in
indicating the provision discovery response events to external programs
especially when the PIN-to-be-displayed was different from the one
returned for the p2p_connect command. Skip this confusing event
completely for join-a-running-group case.

Paul Stewart 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.

Dan Williams 0f4668ceac Try fallback drivers if global init for preferred drivers fails
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
loaded into the kernel, and specified a driver value of "nl80211,wext",
the nl80211 driver's global init would fail with the following message:

nl80211: 'nl80211' generic netlink not found
Failed to initialize driver 'nl80211'

but since global init was a hard failure, creating the supplicant
interface would fail and the WEXT driver would not be tried.
Give other drivers a chance instead.

Jouni Malinen d93dfbd588 Delay scan request on select_network if disconnecting
The disconnection command results in disassociation and deauthentication
events which were previously processed during the scan in case of
select_network command being used while associated with another network.
While this works in most cases, it can result in confusing event
messages in ctrl_iface and debug log. Avoid this by using a short delay
between the disconnection and scan request to allow the disconnection
events to be processed prior to starting the new scan.

Sujith Manoharan 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.
