acc5f4ec60 P2P: Add dbus python scripts to perform p2p_find and p2p_connect
Two DBUS scripts using python glib are added to perform p2p_find and
p2p_connect operations respectively. p2p_connect script just performs
the traditional connect to create a new p2p group. Additional updates
will be required to perform join, auth etc. al.

40a5e3bfde WPS: Add a standalone tool for building NFC password tokens
nfc_pw_token can be used to build random NFC password token for WPS.
This tool prints out the wpa_supplicant.conf (or hostapd.conf)
parameters and the hexdump of the WPS password token (with and without
NDEF encapsulation) so that it can be written to a NFC tag with an
external program.

7c865c6853 Add automatic scanning support
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.

c1c023429b Set state to DISCONNECTED on auth/assoc failures
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.

aa9bb7644b P2P: Allow older scan results to improve p2p_connect-auto robustness
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.

fea7c3a055 Ignore network blocks that have invalid WEP key length
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
without having to reject them during configuration file parsing (which
would prevent wpa_supplicant from starting). The only additional check
added in this commit is to verify the WEP key length. Similar checks for
other parameters can be added in future commits.

c3701c66a5 Add handling of OBSS scan requests and 20/40 BSS coex reports
Add support for HT STA to report 40 MHz intolerance to the associated AP.
A HT station generates a report (20/40 BSS coexistence) of channel list
if it finds a non-HT capable AP or a HT AP which prohibits 40 MHz
transmission (i.e., 40 MHz intolerant bit is set in HT capabilities IE)
from the scan results.

Parse the OBSS scan parameter from Beacon or Probe Response frames and
schedule periodic scan to generate 20/40 coexistence channel report if
requested to do so. This patch decodes Scan Interval alone from the OBSS
Scan Parameters element and triggers scan on timeout.

wpa_drv_scan() may fail for the initial p2p_connect join scan request,
e.g., if the driver happened to be scanning at the time the new
operation was initialized. Previously, a special scan result handler was
registered regardless of whether the new scan was started. This could
result in partial scan results (e.g., from p2p_find social scan) from
being used as full results for join (or now more importantly for
p2p_connect auto) purposes. Fix this by registering the new scan result
handler only if wpa_drv_scan() returns success.
