Even though this is a short timeout, it is at least theoretically
possible for the interface to be removed while waiting for
reconfiguration to start. Avoid issues with this by cancelling the
timeout on any WPS interface deinit. In theory, this should be postponed
until interface removal, but that does not fit very nicely to the
current wps_hostapd.c style.

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.

Action frame RX report through EVENT_RX_ACTION did not indicate whether
the frame was protected or not even though that information is available
in mlme_event_mgmt(). hostapd_rx_action() has a workaround for setting
the protected flag for SA Query frames, but that did not apply for other
frames, like FT Action. This broke FT-over-DS when PMF is enabled with
newer kernel versions (i.e., the ones that do not use monitor interface
for receiving management frames).

This adds first steps at processing a BSS Transition Management Query on
the AP side. Mainly, the message is parsed and printed out in the debug
log and a minimal BSS Transition Management Request frame is sent as a
response. BSS Transition Management Response frame is also parsed and

The previous version could end up calling WPA authenticator routines

Reduce race condition of the station trying to reconnect immediately

This enables more convenient protocol testing of station side
functionality in various error cases and unexpected sequences without
having to implement each test scenario within hostapd.

Wall time jumps shouldn't affect MMIC failure/TKIP countermeasures,
so use monotonic time. Change the michael_mic_failure variable to
struct os_reltime for type-safety.
Signed-hostap: Johannes Berg <johannes.berg@intel.com>
Since the PMKSA cache only uses relative time, use the monotonic time
functions instead of wall time to be correct when the clock jumps.
Signed-hostap: Johannes Berg <johannes.berg@intel.com>
For type-safety, make sta->acct_session_start a struct os_reltime
and then use monotonic time for accounting. For RADIUS reporting,
continue to use wall clock time as specified by RFC 2869, but for
the session time use monotonic time.
Interestingly, RFC 2869 doesn't specify a timezone, so the value
is somewhat arbitrary.

Until now DFS was simply restarting the AP when radar was detected. Now

This is needed for AP CSA. Since CSA must happen immediately after radar

It is possible for the authentication server to be configured with a

Some non-mac80211 drivers, such as ath6kl, support STA inactivity timer

We were not filtering the EVENT_CHANNEL_LIST_CHANGED events based on the
regulatory hint initiator. So wait for EVENT_CHANNEL_LIST_CHANGED event
after our own change was triggered even when regulatory hint initiator
was the driver. This could result in the wait for the channel list to be
updated to be terminated before the real change has occurred and as
such, old channel list remaining in use when configuring
hostapd/wpa_supplicant country parameter. Fix this by filtering the
hints according to the initiator and only regulatory hints initiated by
user will be used to stop the wait.
