Commit aa9bb7644b improved robustness
of p2p_connect-auto mechanism by using older scan results to help in
determination whether the peer was operating a GO. Improve this by
accepting new GO information from scan-for-WPS-provisioning results
even if the GO is not yet ready for WPS.
In addition, fix an issue where Provision Discovery exchange timeout
could have left offchannel TX operation in progress when the fallback
was used.

This is a workaround for interoperability issues with some deployed P2P
implementations that require a Provision Discovery exchange to be used
before GO Negotiation. The new provdisc parameter for the p2p_connect
command can be used to request this behavior without having to run a
separate p2p_prov_disc command.

Excessive debug level can now be used to dump the IEs received in scan
results from both Beacon and Probe Response frames. This makes it easier
to debug issues where the driver (or well, more likely cfg80211) does
not update the IEs based on Beacon frames if even a single Probe
Response frame has been received.

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.

The P2P implementation assumes that the first wpa_s interface instance
is used to manage P2P operations and the P2P module maintains a pointer
to this interface in msg_ctx. This can result in issues (e.g., use of
freed memory) when the management interface is removed. Fix this by
deinitializing global P2P data if the interface that created it is
removed. This will disable P2P until the next interface is added.

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
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.

An existing persistent group information can now be used to force GO
Negotiation to use the previously used SSID/passphrase from a persistent
group if we become a GO. This can be used as an alternative to inviting
a new P2P peer to join the group (i.e., use GO Negotiation with GO
intent 15 instead of starting an autonomous GO and using invitation),

are not running as a GO. The persistent group to use for parameters is

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.
