Jouni Malinen cc22fb1b86 SAE: Move H2E and PK flags to main sae_data
This maintains knowledge of whether H2E or PK was used as part of the
SAE authentication beyond the removal of temporary state needed during
that authentication. This makes it easier to use information about which
kind of SAE authentication was used at higher layer functionality.

Do not include the actual GTK/IGTK value in FT protocol cases in OSEN or
with DGAF disabled (Hotspot 2.0). This was already the case for the
EAPOL-Key cases of providing GTK/IGTK, but the FT protocol case was

would be possible to enable FT in a Hotspot 2.0 network that has DGAF

Hu Wang d578e890eb OWE: Skip beacon update of transition BSS if it is not yet enabled
When a single hostapd process manages both the OWE and open BSS for
transition mode, owe_transition_ifname can be used to clone the
transition mode information (i.e., BSSID/SSID) automatically. When both
BSSs use ACS, the completion of ACS on the 1st BSS sets state to
HAPD_IFACE_ENABLED and the OWE transition mode information is updated
for all the other BSSs. However, the 2nd BSS is still in the ACS phase
and the beacon update messes up the state for AP startup and prevents
proper ACS competion.

If 2nd BSS is not yet enabled (e.g., in ACS), skip beacon update and
defer OWE transition information cloning until the BSS is enabled.

Jouni Malinen 5a04a76aa2 Ignore Management frames while AP interface is not fully enabled
It is possible for drivers to report received Management frames while AP
is going through initial setup (e.g., during ACS or DFS CAC). hostapd
and the driver is not yet ready for actually sending out responses to
such frames at this point and as such, it is better to explicitly ignore
such received frames rather than try to process them and have the
response (e.g., a Probe Response frame) getting dropped by the driver as
an invalid or getting out with some incorrect information.

Jouni Malinen c82535edd6 Move deauthentication at AP start to be after beacon configuration
This allows nl80211-based drivers to get the frame out. The old earlier
location resulted in the driver operation getting rejected before the
kernel was not ready to transmit the frame in the BSS context of the AP
interface that has not yet been started.

While getting this broadcast Deauthentication frame transmitted at the
BSS start is not critical, it is one more chance of getting any
previously associated station notified of their previous association not
being valid anymore had they missed previous notifications in cases
where the AP is stopped and restarted.

Add a new hostapd control interface command "DPP_CHIRP own=<BI ID>

wpa_supplicant functionality from commit 562f77144c ("DPP2: Chirping

started without beaconing, i.e., with start_disabled=1 in hostapd
configuration, to allow iteration of channels needed for chirping.
