Because a delayed scheduled scan will access the members of struct
wpa_supplicant which is freed and this can result in a crash,
wpa_supplicant needs to cancel delayed scheduled scan during cleanups.

Adding a new wpa_supplicant control interface for the dedicated
P2P_DEVICE would be quite confusing for programs that manage P2P
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.

If the capability flag of the driver indicates a dedicated P2P Device is
supported, a P2P Device interface is created.
Create the P2P Device in main interface creation loop when the added
interface flags support and P2P supplicant is not yet initialized
avoiding recursion of add_interface.
Do not register l2_packet for P2P Device interface (both for EAPOL and
for TDLS).

This cleans up debug log by not trying to process the disconnection

There is no point in marking a BSS temporarily blacklisted based on a
connection failure or disconnection case if that happens as a result of
a local request to disconnect. The blacklist entry could result on
unexpected BSS getting selected on the next connection attempt. In
addition, the code to try to find another BSS within the ESS could
result in scanning a single channel on the next attempt. Fix these
issues by handling the connection failure events only if we are not in
disconnected state (i.e., would try to reconnect after this
automatically).

The Hotspot 2.0 specification seems to mandate this element to be
included in all (Re)Association Request frames if the station is Hotspot
2.0 capable. However, that results in conflicts with other requirements
like no TKIP use when this element is present. The design is really
supposed to include the indication element only for Hotspot 2.0
associations regardless of what the current specification implies.
Remove the HS 2.0 Indication element from (Re)Association Request frame
whenever the connection is not for Hotspot 2.0 purposes.

This fixes the lookup of a usable PMKSA entry in the cache. Using

If scan results are available when we perform a SelectNetwork, use
them to make an associate decision. This can save an entire scan
interval-worth of time in situations where something external to
wpa_supplicant (like a connection manager) has just previously
requested a scan before calling SelectNetwork.
Signed-hostap: Paul Stewart <pstew@chromium.org>
When the scan interval is changed the new interval is effective
after the old interval timer fires off one last time. This can cause
an unacceptable long delay when updating the interval.
Change this behaviour to use MIN(left of old interval, new interval)
for the scan interval following the interval change.

This was used to select between "(auth)" and "(reauth)" in
CTRL-EVENT-CONNECTED events. However, the variable was not cleared
anywhere else apart from the AP deinit case. As such, it did not really
provide correct information and is not really of much use even with
proper clearing added. As such, it is cleaner to just get rid of this
altogether.

Commit 1ff733383f added a mechanism to
work around issues due to association events and EAPOL RX events being
getting reordered. However, this applied only for the case where
wpa_supplicant is not in associated state. The same issue can happen in
roaming case with drivers that perform BSS selection internally (or in
firmware). Handle that case similarly by delaying received EAPOL frame
processing if the source address of the EAPOL frame does not match the
current BSSID.
Since wired IEEE 802.1X do not have BSSID, make this additional
workaround conditional on BSSID match having been observed during the
previous association.
This fixes issues where the initial EAPOL frame after reassociation was
either dropped (e.g., due to replay counter not increasing) or replied
to with incorrect destination address (the BSSID of the old AP). This
can result in significantly more robust roaming behavior with drivers
that do not use wpa_supplicant for BSS selection.

wpas_connection_failed() uses the blacklist count to figure out a

wpa_supplicant_{disassociate,deauthenticate}() need to inform the driver
about decision to disconnect even if this happens during the time when
the driver is still trying to complete association. During that time,
wpa_s->bssid is not set, so the code in these functions needs to figure
out the correct BSSID based on that field or wpa_s->pending_bssid. In
addition, it is possible that the BSSID is not even known at
wpa_supplicant at this point in time when using drivers that perform BSS
selection internally. In those cases, the disconnect command needs to be
sent to the driver without the BSSID.
This fixes issues where the driver (or cfg80211 in particular) may be
left in mismatching state with wpa_supplicant when disconnection (e.g.,
due to a ctrl_iface command) happens between connection request and
association event.
