wpa_supplicant signaling after scan in AP mode

[Jose Blanquicet]

Dear all,

When wpa_supplicant is connected as GO-P2P and a Scan request is done,
wpa_supplicant does not deny such request and forwards it toward the
driver. In my case, the full process is completed but once the results
arrives from the driver, wpa_supplicant is refuting to forward them
because it is in AP mode. At this point, upper layer applicants (e.g.
ConnMan) will remain waiting forever for a Interface.ScanDone D-Bus
signal because they successfully performed the Scan request through
Interface.Scan and saw the Scanning property moved to "True".

I am using one of the latest  versions:
wpa_supplicant v2.7-devel-hostap_2_6-979-g290834d

I would say that wpa_supplicant should either refuse the Scan request
from the very beginning or emit such ScanDone signal with the given
results, shouldn't it?

My logs:
