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.

Commit 361cdf3400 changed the way the
group formation timeout is used on P2P client. However, it resulted in
clearing the timeout on the GO when the GO started beaconing. This is
not correct since the timeout is supposed to be maintained until at
least the completion of the WPS provisioning step. Fix this regression
by clearing the timeout here only in the case we are not GO in group
formation phase.

It is possible for wpa_state to be WPA_DISCONNECTED when a new scan is
scheduled to be started in the future. If wpas_wps_cancel() gets called

The previous version set scan_res_handler unconditionally and then

Send an "EAP" signal via the new DBus interface under various

- EAP success and failure messages
This provides DBus callers a number of new tools:
- The ability to probe an AP for available EAP methods
(given an identity).

Use an empty IPv4 packet as the keep-alive packet for WNM BSS max idle

Commit aa9bb7644b improved robustness

This is a workaround for interoperability issues with some deployed P2P

Excessive debug level can now be used to dump the IEs received in scan

Previously, wpa_supplicant did not specify BSSID to any connection
request if the driver indicated that it will take care of BSS selection.
This is fine for most use cases, but can result to issues if the network
block has an explicit bssid parameter to select which BSS is to be used.
Fix this by setting BSSID and channel when the network block includes the
bssid parameter even if the driver indicates support for BSS selection.

If WPS commands are used with a specific BSSID instead of wildcard,
the BSSID that was supposed to be used only for the provisioning step
may end up getting copied to the network block that gets provisioned
based on the WPS credentials. Fix this by clearing ssid->bssid_set
when creating the network block by replacing the block used for WPS
provisioning.
This issue could show up with the provisioned network not getting
selected properly with APs that have multiple radios. Depending on
the driver, this could result in only a single one of the available
BSSes being available or the connection failing completely.

Previusly the peer was assumed to not be operating a GO if the BSS entry
for it was not updated in the single scan run started by
p2p_connect-auto. This is not very robust since a scan may miss the peer
if either a Probe Request or Probe Response frame is lost. Improve
robustness by assuming the peer is still operating the GO and starting
the join operation. If the GO is not found during PD-for-join or the
single-channel scans during the join, fall back to GO Negotiation.

Do not try to associate with a network that has an invalid or incomplete
configuration because the association or at least data connection would
fail anyway. This commits adds a common function for checking whether a
network block is disabled to make it easier to check network blocks
