It was possible for the RSN state machine to maintain old PMKSA cache
selection (sm->cur_pmksa) when roaming to another BSS based on
driver-based roaming indication. This could result in mismatching state
and unexpected behavior, e.g., with not generating a Suite B PMKSA cache
entry.

wpa_supplicant registered to process the Radio Measurement Request
frames unconditionally. This would prevent other location based
applications from handling these frames. Enable such a use case by
allowing wpa_supplicant to be configured not to register to process
these frames. This can now be done by adding "no_rrm=1" to the
driver_param configuration parameter.
In addition, wpa_driver_nl80211_init() does not have the provision to
take driver_params. Hence, resubscribe again with cfg80211 when this
driver parameter "no_rrm=1" is set after the initial setup steps.

While adding support for IGTK and BIGTK here, I tested this without
protections (i.e., with protections removed from both wpa_supplicant and

should have failed with "unexpected connectivity".
Fix this to be correct - we need to reset the GTK PN, not the PTK PN in
this test.

Use a shared wpa_alg_bip() function for this and fix the case in

with IGTK.

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..

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.
