8f38eed628 Android: Remove superfluous OpenSSL include paths
The libcrypto and libssl modules (and their respective static and host
versions) use LOCAL_EXPORT_C_INCLUDE_DIRS thus just including the module
is sufficient.

cbf8d181c3 HS 2.0R2: Clear fetch_anqp_in_progress if fopen fails
Clear wpa_s->fetch_anqp_in_progress when osu-providers.txt can't be
opened. An issue happens, for instance, when wpa_supplicant doesn't
have correct access permission to the directory specified by osu_dir.
If hs20_osu_fetch_done method returns without clearing the flag,
'FETCH_OSU' command will never work correctly.

bef5e9a862 Fix scan rescheduling from wpas_stop_pno to check postponed case
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.

debde14b5b RADIUS: Add Acct-Delay-Time into accounting messages
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.

where RADIUS message delivery fails. This allows the server to get up to

the old information from the time the first failed attempt was sent.

170c545ab4 FT: Check destination MAC address on RRB receive
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.

57b2c9140c RADIUS: Allow RADIUS server to provide PSK instead of passphrase
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

f8e09bc57e Defer passphrase-to-PSK hashing out of 802.11 authentication ACL check
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.

d48d1b88d0 FT: Use BSSID as r1_key_holder if no value is configured
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.

186ca4736d tests: FT RRB internal delivery to non-WPA BSS
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

0270bdedcc FT: Fix R0KH-R1KH protocol data length values
The FT RRB hostapd packets have a length field. For PULL frames, it
counted the bytes starting with nonce and up to the last before pad. For
RESP frames, it counted the bytes starting with nonce and up to the last
before pad except for 2 bytes. For PUSH frames, it counted the bytes
starting with nonce and up to including pad.

As rounding is done with AES encryption, including pad does not make
sense. Not including the last field before pad does not make sense
either. These were broken in the earlier addition of the 2 octet
pairwise field in commit 1b484d60e5 ('FT:
Include pairwise cipher suite in PMK-R0 SA and PMK-R1 SA').

AES encryption is not affected, as rounding hides the differences. The
packets data_length field is not used, so the differences have no effect
there.

This patch changes the constants to match the bytes used, thus excluding
the pad. To validate the changes, look at remainder modulo 8 of the sum
of the size constants and the padding sizes.

itself and not the p2p_dev interface.

Fix this by adding a separate "p2pdev" pointer to wpa_supplicant,
it will be the same as parent pointer in most cases but whenever

point to the correct p2p_dev interface.
