aa189ac9dd Enable FT with SAE
It was already possible to configure hostapd and wpa_supplicant to use
FT-SAE for the key management, but number of places were missing proper
AKM checks to allow FT to be used with the new AKM.

759fd76b7f P2P: Select PSK based on Device Address instead of Interface Address
When using per-device PSKs, select the PSK based on the P2P Device
Address of the connecting client if that client is a P2P Device. This
allows the P2P Interface Address to be changed between P2P group
connections which may happen especially when using persistent groups.

This can be used to implement per-device PSK selection based on the
peer's P2P Device Address instead of P2P Interface Address.

901d1fe1e5 WNM: Remove PMKSA cache entry on ESS disassoc imminent notification
This is needed to avoid allowing the STA to reconnect using a cached
PMKSA. ESS disassoc imminent notification is normally used to indicate
that the STA session will be terminated and as such, requiring full
authentication through the authentication server after this is needed.

7af092a015 hostapd: Add Key MIC in group EAPOL-Key frames corruption test option
For some testing it can be useful to force the Key MIC in group
EAPOL-Key frames to be corrupt. Add an option to allow setting a
probability for corrupting the Key MIC and use it in the WPA code,
increasing the first byte of the MIC by one to corrupt it if desired.

ad3872a372 WNM: Use CONFIG_WNM more consistently
Replace CONFIG_IEEE80211V with CONFIG_WNM to get more consistent build
options for WNM-Sleep Mode operations. Previously it was possible to
define CONFIG_IEEE80211V without CONFIG_WNM which would break the build.
In addition, IEEE 802.11v has been merged into IEEE Std 802.11-2012 and
WNM is a better term to use for this new functionality anyway.

c772d054c2 hostapd: Fix a regression in TKIP countermeasures processing
Commit 296a34f0c1 changed hostapd to
remove the internal STA entry at the beginning of TKIP countermeasures.
However, this did not take into account the case where this is triggered
by an EAPOL-Key error report from a station. In such a case, WPA
authenticator state machine may continue processing after having
processed the error report. This could result in use of freed memory.
Fix this by stopping WPA processing if the STA entry got removed.

c10347f246 Add initial parts for SAE
This introduces new AKM for SAE and FT-SAE and adds the initial parts
for going through the SAE Authentication frame exchange. The actual SAE
algorithm and new fields in Authentication frames are not yet included
in this commit and will be added separately. This version is able to
complete a dummy authentication with the correct authentication
algorithm and transaction values to allow cfg80211/mac80211 drivers to
be tested (all the missing parts can be handled with
hostapd/wpa_supplicant changes).

8342185012 HS 2.0: Add mechanism for disabling DGAF
disable_dgaf=1 in hostapd.conf can now be used to disable downstream
group-addressed forwarding (DGAF). In this configuration, a unique
GTK (and IGTK) is provided to each STA in the BSS to make sure the
keys do not match and no STA can forge group-addressed frames.

An additional mechanism in the AP needs to be provided to handle some
group-addressed frames, e.g., by converting DHCP packets to unicast
IEEE 802.11 frames regardless of their destination IP address and by
providing Proxy ARP functionality.

bdffdc5ddb AP: Reorder WPA/Beacon initialization
Split WPA initialization into two parts so that the Beacon frames can be
configured fully before the initial keys (GTK/IGTK) are configured. This
makes it easier for drivers that depend on the AP security mode being
fully set before the keys are configured.

cb465555d4 Allow PMKSA caching to be disabled on Authenticator
A new hostapd configuration parameter, disable_pmksa_caching=1, can now
be used to disable PMKSA caching on the Authenticator. This forces the
stations to complete EAP authentication on every association when WPA2
is being used.

e4bf4db907 Work around SNonce updates on EAPOL-Key 1/4 retransmission
Some deployed supplicants update their SNonce for every receive
EAPOL-Key message 1/4 even when these messages happen during the
same 4-way handshake. Furthermore, some of these supplicants fail
to use the first SNonce that they sent and derive an incorrect PTK
using another SNonce that does not match with what the authenticator
is using from the first received message 2/4. This results in
failed 4-way handshake whenever the EAPOL-Key 1/4 retransmission
timeout is reached. The timeout for the first retry is fixed to
100 ms in the IEEE 802.11 standard and that seems to be short
enough to make it difficult for some stations to get the response
out before retransmission.

Work around this issue by increasing the initial EAPOL-Key 1/4
timeout by 1000 ms (i.e., total timeout of 1100 ms) if the station
acknowledges reception of the EAPOL-Key frame. If the driver does
not indicate TX status for EAPOL frames, use longer initial
timeout (1000 ms) unconditionally.

1b484d60e5 FT: Include pairwise cipher suite in PMK-R0 SA and PMK-R1 SA
This is needed to fix PTK derivation to use correct length. Previously,
64-octet PTK may have been derived if the authenticator did not already
have a STA entry. Now, the correct pairwise cipher suite is learned when
then PMK-R1 SA is received.

70f8cc8ec8 Share the same enum for MFP configuration
The three existing enums were already depending on using the same
values in couple of places and it is just simpler to standardize on
one of these to avoid need for mapping between different enums for
