P2P-GROUP-STARTED event depends on having enough information about the

upper layers, do not accept scan results without P2P IE (e.g., from a

When the BSS table is being updated based on new scan results, a BSS
entry could end up getting added into last_scan_res list multiple times
if the scan results from the driver includes duplicated values. This
should not happen with driver_nl80211.c since it filter outs duplicates,
but in theory, other driver wrappers could indicate such scan results.
Anyway, it is safer to make sure this cannot happen by explicitly
verifying the last_scan_res list before adding an updated BSS entry
there. A duplicated entry in the list could potentially result in freed
memory being used if there is large enough number of BSSes in the scan
results to cause removal of old BSS entries.

If there are large number of BSSes in the scan results, BSS table update
could have added a BSS entry to the last_scan_res in a case where that
BSS entry got just deleted. This would happen only if there are more
than bss_max_count (by default 200) BSSes and if at least bss_max_count
of those BSSes are known (match a configured network). In such a case,
wpa_bss_add() could end up allocating a new BSS entry and return a
pointer to that entry even if it was the one that ended up getting freed
to keep the BSS table length within the limit. This could result in
freed memory being used and the process crashing (likely with segfault)
when trying to access information from that BSS entry.
Fix the issue by removing the oldest BSS entry before linking the new
entry to the table. This makes sure the newly added entry will never get
picked up as the one to be deleted immediately.

If wpa_supplicant ctrl_iface clients are misbehaving and refusing to
read replies or event messages from wpa_supplicant, the single socket
used in wpa_supplicant to send messages can reach the maximum send
buffer limit. When that happens, no more responses to any client can be
sent. Work around this by closed and reopening the socket in case such a
failure state is detected. This is obviously not desirable since it
breaks existing connected sockets, but is needed to avoid leaving
wpa_supplicant completely unable to respond to any client. Cleaner fix
for this may require more considerable changes in the ctrl_iface design

It is possible for the GO of a persistent group to change the PSK or
remove a client when per-client PSKs are used and this can happen
without the SSID changing (i.e., the group is still valid, but just not
for a specific client). If the client side of such persistent group ends
up trying to use an invalidated persistent group information, the
connection will fail in 4-way handshake. A new WPS provisioning step is
needed to recover from this.
Detect this type of case based on two 4-way handshake failures when
acting as a P2P client in a persistent group. A new
"P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to
indicate when this happens. This makes it easier for upper layers to
remove the persistent group information with "REMOVE_NETWORK <persistent
group id>" if desired (e.g., based on user confirmation).

To better support the IBSS/RSN mechanism, wpa_supplicant has to be able
to detect a possible peer reboot and in this case it should start a new
EAPOL handshake.
To perform such reboot detection wpa_supplicant has to perform an Open
Authentication by sending an Authentication frame and then replying to
it. IF an Authentication frame is received when the key have already
been exchanged, wpa_supplicant understands that the peer has rebooted
and can reset its state machine.
Whenever a new peer is added to the IBSS wpa_supplicant will start the
Open Authentication and only after having accomplished it will start the
key exchange. If the driver does not support Authentication frame
exchange initiated from user space, this step is skipped to maintain
previous behavior (just go through EAPOL-Key frame processing).

operations. Remove this control interface and require the global control
interface to be used since it will provide consistent interface for both
the new dedicated P2P_DEVICE (non-netdev) and old style P2P management
through a netdev.

Commit c68f6200a7 made these calls
conditional on !p2p_mgmt, but forced p2p_mgmt=1 for cases where the
driver does not use the dedicated P2P Device. Fix this by making the
!p2p_mgmt condition apply only if the driver does indicate use of a
dedicated P2P Device.

The interface name for the P2P group interface is derived from the
P2P management interface. When the P2P management interface is a
P2P Device interface, i.e., p2p-dev-wlanX, the name for the group
interface is abbreviated to p2p-X (X being group index). When the
P2P management interface starts with p2p-dev- use its postfix
instead. So P2P management interface p2p-dev-wlan3 results in group
interface name p2p-wlan3-0.
