This allows FFC groups to be used with SAE. Though, these groups are not
included in the default sae_groups value based on what is available
since the FFC groups have the additional requirement of using a safe
prime with the current implementation (or specification of the group
order).

hostapd can now be configured to use anti-clogging mechanism based on

The -N and -C command line parameters can be used to add arbitrary
RADIUS attributes to the messages. However, these were truncated to

of payload) to be used. [Bug 458]

Verify that the other BSS has actually received some valid ANQP
information before sharing the results from it. This fixes potential
issues with cases where some of the APs with the same HESSID has invalid
ANQP configuration.

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.

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 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.

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.

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.

Add some more functionality for BSS Transition Management:
- advertise support for BSS Transition Management in extended
capabilities element
- add hostapd.conf parameter bss_transition=1 for enabling support
for BSS Transition Management
- add "hostapd_cli disassoc_imminent <STA> <num TBTTs>" for sending
disassociation imminent notifications for testing purposes
- wpa_supplicant: trigger a new scan to find another BSS if the
current AP indicates disassociation imminent (TODO: the old AP needs
to be marked to use lower priority to avoid re-selecting it)

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.

Network blocks are disabled during a WPS provisioning step and 10
seconds after this to allow the newly provisioned network to be
selected. The disabled=1 flag gets written to the configuration file
when the credential is added since it happens during this process.
Update the file again after the networks have been re-enabled to avoid
leaving the configuration file into state that is not consistent with
the running configuration.

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.
