When p2p_find is stopped, send request to the driver

Currently, when scan is stuck in the kernel/driver/fw,
the nl80211 driver tries to recover by faking a SCAN_RESULTS flow.
However, the scan is still stuck in the kernel/driver/fw.
To avoid that stuck request, abort it upon scan timeout.

Test different delay intervals between the INTERFACE_DISABLED event
and the INTERFACE_ENABLED event for discovery_and_interface_disabled.
Previously, only a delay of 1 second was used, in which case the
scan results for the P2P_FIND operation were received after the
interface was enabled again, and the case the scan results were
received while the interface was disabled was not covered.
Signed-off-by: Ilan Peer <ilan.peer@intel.com>
An interface can be disabled while it has an ongoing scan request.
In such a case, when the scan results notification is received,
it was being ignored (as the interface is already disabled) so the
scan state was not cleared. This can cause undetermined behavior
for the next scan request.
To handle this, clear the scan state when EVENT_SCAN_RESULTS is
received and the interface is disabled.

Verify that when the Candidate List Included bit is set in a BSS
Transition Management Request frame, the candidate list actually
includes at least one candidate. If no candidates are included, reject
the request without scanning.
Signed-off-by: Avraham Stern <avraham.stern@intel.com>
In BSS Transition Management Request frame, it is possible that vendor
specific IEs are included after the candidate list. In this case the
candidates count was incremented for each IE although the candidate list
is already over which could result in adding all zeros candidates into
the neighbor list.
Fix that by incrementing the candidates count only for neighbor report
elements.

Commit 02e122a995 ('Reschedule scan from
wpas_stop_pno if it was postponed') uses wpa_s->scanning as the only
condition for automatically starting a postponed scan request from
EVENT_SCHED_SCAN_STOPPED event handler. However, wpa_s->scanning may be
set for sched_scan and as such, this can result in unexpected extra
scans without there having been any real postponed request.
Make this more accurate by verifying that there really is a pending
request for a scan before speeding up its start.

This tells to the server how long we have been trying to transmit the
message so that the actual time of the message generation can be
determined from receive time (ignoring network delays and only at
accuracy of one second).
For interim updates, only value 0 is used since there are no
retransmissions of the same message. For other accounting messages, the
initial attempt goes out with value 0 and the retransmissions, if
needed, show the number of seconds the message has been waiting in the
queue.
Update the Identifier and Authenticator in the messages whenever
updating the Acct-Delay-Time per RFC 2866, 4.1 requirements.

Instead of using the RADIUS client retransmission design with the old
RADIUS message contents for each retry, trigger a completely new interim
accounting update instance more quickly (using the same schedule as
RADIUS message retransmissions) to improve accounting updates in cases
where RADIUS message delivery fails. This allows the server to get up to
date information from the time the "retry" message was sent instead of
the old information from the time the first failed attempt was sent.

As the Linux variant of l2_packet_init() does not use its own_addr
argument and l2_packet_receive() does not filter on destination MAC
address, this needs to be checked in the callback.
If there are multiple BSSes listening for FT RRB packets, all their
BSSIDs need to be local to the bridge interface. As l2_packet_init() is
going to receive all of them going for any local address, those RRB
messages started turning up on BSSes that were not destinated for and
cluttering logs.

If the AP is slow, passphrase hashing takes too long to serve the client
before timeout. Extend the Tunnel-Password design to allow a 64
character value to be interpreted as a PSK and send SSID to RADIUS
server. This allows the RADIUS server to either take care of passphrase
hashing or to use raw PSK without such hashing.
This is especially important for FT-PSK with FT-over-air, where hashing
cannot be deferred.

Instead of copying the full struct hostapd_sta_wpa_psk_short, share the
existing entry and use reference counting to check when it needs to be
freed. This allows caching of PSKs derived from passphrases to avoid
having to perform the heavy hashing operation multiple times.

Hashing takes quite some time (can be about one second on a low-power
CPU for each passphrase provided), so hostapd can easily hit the 900 ms
Wi-Fi client authentication deadline (mac80211 uses 3x 300 ms). This can
be fixed by storing the passphrase instead of PSK with the STA and defer
the hashing into the WPA/RSN 4-way handshake, when enumerating all PSKs.
This applies for the case where a RADIUS server is used to store the
per-STA passphrases and this passphrase is delivered as part of the MAC
ACL check during IEEE 802.11 Authentication frame processing.

r1_key_holder is an identifier that was always set to zero if unless
configured before.
See 11.6.1.7.4 of IEEE Std 802.11-2012 which reads
"R1KH-ID is a MAC address of the holder of the PMK-R1 in the
Authenticator of the AP"
See 12.2.2 of IEEE Std 802.11-2012 which reads
"Each R0KH-ID and R1KH-ID is assumed to be expressed as a unique
identifier within the mobility domain."
"The R1KH-ID shall be set to a MAC address of the physical entity
that stores the PMK-R1 ..."
Defaulting this to BSSID is a more reasonable value since we have not
rejected the missing r1_key_holder as invalid configuration.

A malicious station could try to do FT-over-DS with a non WPA-enabled
BSS. When this BSS is located in the same hostapd instance, internal RRB
delivery will be used and thus the FT Action Frame will be processed by

hapd->wpa_auth is NULL.
This test implements such a malicious request for regression testing.
