It was apparently possible to hit the 20000 octet limit in some cases,
so increase the limit to avoid process termination due to insufficient
room for preparing a response to Introspect calls.

This is not really appropriate for any kind of cross compilations and is
not really needed in general since system specific values can be set in
.config.

The previous implementation used mp_rand_prime() to generate a random
value in range 0..m. That is insanely slow way of generating a random
value since mp_rand_prime() is for generating a random _prime_ which is
not what is needed here. Replace that implementation with generationg of
a random value in the requested range without doing any kind of prime
number checks or loops to reject values that are not primes.
This speeds up SAE and EAP-pwd routines by couple of orders of
magnitude..

When run after other tests, It was likely that the target
bss was already present in scan_fail, so the
scan_for_bss() wouldn't trip the allocation failure in
wpa_bss_add(). Flush the scan results before the scan to
ensure wpa_bss_add() is called and consistently pass
scan_fail.

Commit dd74ddd0df ("nl80211: Handle AKM suite selectors for AP
configuration") added warning log message "nl80211: Not enough room for
all AKM suites (num_suites=X > NL80211_MAX_NR_AKM_SUITES)" which in some
cases fills logs every 3 seconds, so fix this by increasing the log

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.
Signed-off-by: Jouni Malinen <j@w1.fi>
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.

cfg80211 takes care of key removal when link/association is lost, so

Linux bridging code does not allow a station mode WLAN interface in a
bridge and this prevents the AP mode scan workaround from working if the
AP interface is in a bridge and scanning can be only done by moving to
STA mode. Extend this workaround to remove the interface from the bridge
temporarily for the duration of the scan, i.e., for the same duration as
the interface needs to be moved into the station.

Address possible handover request collisions for cases where both
devices try to initiate handover simultaneously.
Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
The previous version was trying to force the handover roles based on the
--init-on-touch parameter on both sides. That is fine for some test
scenarios, but not appropriate for more normal use cases. Change this
design to enable handover server in all cases and only control starting
of the handover client based on --init-on-touch.

Add a new hostapd control interface command "DPP_CHIRP own=<BI ID>
iter=<count>" to request chirping, i.e., sending of Presence
Announcement frames, to be started. This follows the model of similar
wpa_supplicant functionality from commit 562f77144c ("DPP2: Chirping
in wpa_supplicant Enrollee"). The hostapd case requires the AP to be
started without beaconing, i.e., with start_disabled=1 in hostapd
configuration, to allow iteration of channels needed for chirping.

The driver can advertise supported AKMs per wiphy and/or per interface.
Populate per interface supported AKMs based on the driver advertisement
in the following order of preference:
1. AKM suites advertised by NL80211_ATTR_IFTYPE_AKM_SUITES
2. AKM suites advertised by NL80211_ATTR_AKM_SUITES
If neither of these is available:
3. AKMs support is assumed as per legacy behavior.
In addition, extend other driver interface wrappers to set the
per-interface values based on the global capability indication.

Since this functionality was not used for anything in practice, it is
