79488da576 wolfssl: Do not hardcode include directory in wpa_supplicant build
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.

eb595b3e3a wolfssl: Fix crypto_bignum_rand() implementation
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..

692bbd25b4 tests: Flush scan results before checking alloc failure
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.

3e1a130107 nl80211: Change AKM suite limit from warning to debug print
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
message level to debug.

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.

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.

04030e8c0d nl80211: Remove AP mode interface from bridge for STA-mode-scan
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.

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.

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.
