d6bbcce411 Make wpas_select_network_from_last_scan() static
Addition of wpa_supplicant_fast_associate() made it unnecessary to call
wpas_select_network_from_last_scan() directly from other files.

cecdddc184 wpa_supplicant: Implement fast-associate on SelectNetwork
If scan results are available when we perform a SelectNetwork, use
them to make an associate decision.  This can save an entire scan
interval-worth of time in situations where something external to
wpa_supplicant (like a connection manager) has just previously
requested a scan before calling SelectNetwork.

9e737f08d4 Update scan interval gracefully
When the scan interval is changed the new interval is effective
after the old interval timer fires off one last time. This can cause
an unacceptable long delay when updating the interval.

Change this behaviour to use MIN(left of old interval, new interval)
for the scan interval following the interval change.

085b29f1fe hostapd: Fix crash when scan fails
When scan failed, the wpa_driver_nl80211_scan method tried
to recursively call itself, but it passed in the wrong argument
for the void*, and so then it crashed accessing bad memory.

With this fix, hostapd still will not retry the scan later, but
at least it will exit cleanly and won't polute the file system
with core files.

624b4d5a64 P2P: Use the same Dialog Token value for every GO Negotiation retry
Each GO Negotiation Request is (re)tried with an unique dialog token and
a GO Negotiation Response / Confirmation from the peer with a mismatched
dialog token is ignored which could result in a failure in this group
formation attempt. Thus, the P2P device would continue retrying the GO
Negotiation Request frames till the GO Negotiation Response frame with a
matching dialog token is received. To avoid the failures due to the
dialog token mismatch in retry cases if the peer is too slow to reply
within the timeout, the same dialog token value is used for every retry
in the same group formation handshake.

It should be noted that this can result in different contents of the GO
Negotiation Request frame being sent with the same dialog token value
since the tie breaker bit in GO Intent is still toggled for each
attempt. The specification is not very clear on what would be the
correct behavior here. Tie breaker bit is not updated on
"retransmissions", but that is more likely referring to the layer 2
retransmission and not the retry at higher layer using a new MMPDU.
