If there are any disabled networks, show a debug print with the count
of those networks when no enabled networks are found. This can be
helpful in trying to figure out why scans are being skipped.

The ASCII hexdump is somewhat difficult to search for (especially on
Android builds), so make the debug log easier to parse by printing the
full control interface command as a text string. In addition, use
wpa_dbg() to get the interface name printed so that multi-interface
cases can be debugged.

Setting just ssid->passphrase is not enough to complete the network
block for the GO entry. Also the PSK needs to be derived so that the
network is considered enabled by wpas_network_disabled(). The previous
version worked as long as something else allowed the scan request to be
performed (this is needed even though the actual scan is skipped when
starting GO).
The first GO start was allowed because wpa_s->scan_req is initialized to
1 in wpa_supplicant_alloc(). However, other attempts may fail if
wpa_s->scan_req is cleared. This failure shows up as "No enabled
networkas - do not scan" in debug log followed by state change to
INACTIVE when trying to start GO.
Fix this by deriving PSK from the passphrase for GO mode.

Commit 30ee769235 started skipping P2P
group removal if wpa_s->current_ssid is not set and commit
0d30cc240f started clearing
wpa_s->current_ssid on disconnection. This combination broke
p2p_group_idle timeout on P2P client interface in a case where no
separate P2P group interface is used and when the disconnection is
triggered by something else than an explicit indication of GO
terminating the group.
Fix this by relaxing network block matching rules when figuring out
whether any of the configured network blocks could be in P2P use. The
p2p_group flag alone should be enough for this since temporary P2P group
network blocks are removed once the P2P group is terminated.

If a connection operation is started on an interface based on scan
results, other virtual interfaces should not be information about the
results to avoid potential concurrent operations during the association
steps. Since the sibling notification of scan results received was added
as an optimization, skipping it for this type of cases is the simplest
way of avoiding unnecessary concurrent operations.

This makes sure that the interrupted station mode scan can be completed

Driver could reject the new scan based on any virtual interface
running a concurrent scan. As such, mark the pending scan callback
for P2P based on any interfaces instead of just the one used for
the p2p_scan operation.
Signed-hostap: Jouni Malinen <j@w1.fi>
Since we have a global P2P module, the flag to trigger scan completion
events to it needs to be in similar context. The previous design
maintained this separately for each virtual interface and if P2P module
did not run its scan operation on the virtual interface that completed
the scan, P2P module would not be allowed to restart operations
properly.

If the REMOVE_NETWORK command is used to delete the currently connected
network, some operations were run between removing the network and
clearing of wpa_s->current_ssid. This left wpa_s->current_ssid pointing
to freed memory and should any operation end up using it before the
pointer gets cleared, freed memory could be references. Avoid this by
removing the network only after having completed the operations that
clear wpa_s->current_ssid.

Commit 0d30cc240f forced

wpa_supplicant_mark_disassoc() which gets called from
wpa_supplicant_event_disassoc(). This broke IEEE 802.1X authentication
failure processing and P2P deauthentication notification (group

Fix this by splitting wpa_supplicant_event_disassoc() into two parts and
make wpas_p2p_deauth_notif() indicate whether the interface was removed.
If so, the last part of disassocition event processing is skipped. Since
the wpa_supplicant_mark_disassoc() call is in the second part, the above
mentioned issues are resolved. In addition, this cleans up the P2P group
interface removal case by not trying to use fast reconnection mechanism
just before the interface gets removed.

This allows both hostapd and wpa_supplicant to be used to derive and

configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in

CCMP could have been used.
