d136c376f2 SAE: Add support for Anti-Clogging mechanism
hostapd can now be configured to use anti-clogging mechanism based on
the new sae_anti_clogging_threshold parameter (which is
dot11RSNASAEAntiCloggingThreshold in the standard). The token is
generated using a temporary key and the peer station's MAC address.
wpa_supplicant will re-try SAE authentication with the token included if
commit message is rejected with a token request.

d03f1e5d63 eapol_test: Allow full RADIUS attribute length to be used
The -N and -C command line parameters can be used to add arbitrary
RADIUS attributes to the messages. However, these were truncated to
about 128 bytes when the actually message was constructed. Fix this by
using larger buffers to allow the maximum attribute length (253 octets
of payload) to be used. [Bug 458]

d1ec319f12 Interworking: Continue ANQP fetch after TX failure
If the driver rejected any of the offchannel Action frame TX requests,
the previous implementation terminated ANQP fetch process. While the
driver should not really reject the request normally, it is possible
that a request gets rejected for some reason. Allow the fetch process to
continue with the next AP in such case to avoid breaking networking
selection. This could result, e.g., in auto_interworking=1 process
failing to connect if any the driver rejects requests to any of the APs
in the scan result even if some other APs provided suitable information.

1cfc678723 Remove reassociated_connection variable
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.

6350a148c4 P2P: Be more careful with wpa_config_update_psk() call
Commit bb4d4deb4b introduced a code path
that could potentially end up calling wpa_config_update_psk() with NULL
passphrase. While that may not happen in practice, it is better to make
sure it doesn't happen since that function will dereference the
passphrase pointer unconditionally.

bb4d4deb4b P2P: Allow PSK to be used instead of passphrase for persistent GO
This continues optimizations for use of CPU heavy pbkdf2_sha1() in GO
setup after the earlier commit 30c371e8a5
by allowing PSK to be used instead of passphrase when creating
persistent group information manually for the GO.

It should be noted that this would not meet the requirements in the P2P
specification (GO shall maintain the passphrase), so this should be used
only when there is no need to allow manual configuration of legacy STAs
using the passphrase.

3dfd0484fc P2P: Consider age for the P2P scan results
cfg80211 caches the scan results according the channel number. Due to
the 15 sec aging this might cause the user mode to see more than one
scan result with the same BSSID, e.g. - one scan result for the
P2P Device and one for the P2P GO (once it's enabled).

Fix this by updating the device entry only if the new peer entry is
newer than the one previously stored.

3ab35a6603 Extend EAPOL frames processing workaround for roaming cases
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.

Commit 17a4734dc4 shall optimize the
post-WPS scan based on the channel used during the provisioning only
when the EAP-Failure frame is received. In cases where the EAP-Failure
frame is missed, this optimization shall not happen resulting in the
scan in all the channels thus consuming more time for the connection.
This commit enhances this by storing the requisite information after
the M8 frame is received.
