407be00b6c P2P: Postpone P2P scan only if station mode scan is pending
sta_scan_pending was supposed to be accurate enough for determining
whether a P2P scan needs to be postponed. However, it has turned out
that there were cases where sta_scan_pending was not cleared properly.
While the known cases have now been addressed, it is possible that some
other cases may still exist. To avoid issues with P2P operationg getting
stuck, verify more carefully that there is a real pending station mode
scan (either in progress or scheduled to be requested).

cfd31b5026 Use special scan result processing steps only on requesting interface
Scan result events are shared between all virtual interfaces sharing the
same radio. However, some of the steps are not really appropriate on
virtual interfaces that did not issue the scan request. Fix this by
making these steps conditional on the scan results being processed on
the interface that requested them.

b1cd021e29 P2P: Re-start P2P operation if station mode scanning is stopped
There were couple of code paths that could end up stopping station mode
scanning without clearing sta_scan_pending. This could result in P2P
search getting stuck waiting for completion of station mode scan which
would never show up. Fix this by calling wpas_p2p_continue_after_scan()
in cases where station mode scans are stopped. This allows
sta_scan_pending to be cleared and P2P search operation continued.

Add a driver capability flag for drivers which support IBSS mode and set
it for nl80211 drivers which have set the NL80211_IFTYPE_ADHOC.

Add a new option "modes" to "get_capability" which will return "AP" and
"IBSS" if the corresponding capability flags are set.

dbca75f82a P2P: Remove persistent group peer if it rejects invitation
If a peer replies to persistent group invitation with status code 8
(unknown group), remove the peer from the p2p_client_list if we are the
GO or remove the persistent group if we are the P2P client since it
looks like that the peer has dropped persistent group credentials and
the provisioning step needs to be executed again.

b277a2bebc P2P: Allow shared interface channel preference to be ignored
p2p_ignore_shared_freq=1 in the configuration file (or "SET
p2p_ignore_shared_freq 1" on control interface) can now be used to
configure wpa_supplicant to ignore the preference on shared operating
channel when the driver support multi-channel concurrency. The default
behavior is to try to start any new P2P group on an operating channel
that is already in use on another virtual interface to avoid extra cost
from hopping between multiple channels. If this new parameter is set to
1, such preference is not used and instead, the channel for the new P2P
group is selected based on other preferences while ignoring operating
channels of any concurrent connection.

6cb27aa85f P2P: Fix shared frequency preference for concurrent operations
Commit 50285f5ca8 changed number of rules
in channel selection and among other things, it broke the design where
the currently used operating channel on a virtual interface that is
shared by the same radio is preferred to avoid costs related to
multi-channel concurrency. Fix this regression by making the P2P module
aware of the shared channel and using that preference as the highest
priority when re-selecting the channel during negotiation.

77e4e85321 P2P: Mark peer authorized for persistent group invitation
When p2p_invite persistent=<id> is used to request a persistent group to
be re-invoked, the peer may reply with status=1 (info not yet available)
if upper layer processing of the invitiation is requested. The peer is
ten expected to start another invitation exchanged within 120 seconds if
the user authorizes the connection. Allow this process to be used more
easily by automatically authorizing the peer that we tried to invite to
use this second invitation sequence even if persistent_reconnect=0.

For this mechanism to work, the device that starts the invitation needs
to start listen mode to be able to receive the invitation request from
the peer. At least for now, this is not done automatically, but future
changes could potentially enable this automatically at least if there
are no concurrent operations in progress.

Example sequence on the initiator:

cmd: P2P_INVITE persistent=1 peer=<addr>
event: P2P-INVITATION-RESULT status=1
cmd: P2P_LISTEN 120
wait for peer to start another invitiation round.. group will be
re-invoked automatically

On the peer (with persistent_reconnect=0):

event: P2P-INVITATION-RECEIVED sa=<addr> persistent=1 [freq=<MHz>]
wait for user approval
cmd: P2P_INVITE persistent=1 peer=<addr>
group will be re-invoked automatically

cd1e2309a2 P2P: Indicate frequency for upper layer invitation processing
When a device that is a GO in a persistent group receives an Invitation
Request from a P2P client and persistent_reconnect=0, upper layer is
notified of this with P2P-INVITATION-RECEIVED event. The upper layer is
supposed to run another invitation exchange is this case, but if that
does not happen and the GO is started without successful (status=0)
invitation exchange, the operating channel for the group may end up
getting set in a way that the P2P client is not able to support. Provide
optional freq parameter in the P2P-INVITATION-RECEIVED event on the GO
side. If this parameter is received and the upper layer decides to issue
P2P_GROUP_ADD command, that command should include this freq parameter
to make sure the operating channel gets selected from the set that the
peer can support.
