Unsolicited broadcast Probe Response transmission is used for in-band
discovery in the 6 GHz band (IEEE P802.11ax/D8.0 26.17.2.3.2, AP
behavior for fast passive scanning). Add support for configuring the

Add hostapd configuration options for unsolicited broadcast
Probe Response transmission for in-band discovery in 6 GHz.
Maximum allowed packet interval is 20 TUs (IEEE P802.11ax/D8.0
26.17.2.3.2, AP behavior for fast passive scanning).
Setting value to 0 disables the transmission.

Number of the P2P+NFC test cases have been failing every now and then
and those failures seemed to be because of having somehow managed to
select the GO's operating channel as HT40+ on the channel 11 in the 2.4
GHz band, i.e., something that is clearly incorrect. The P2P check for
HT40 secondary channel is supported only on the 5 GHz band, so drop HT40
configuration if it shows up unexpectedly on the 2.4 GHz band to avoid
issues in GO being able to start.

nl80211_set_4addr_mode() could fail when trying to enable 4addr mode on
an interface that is in a bridge and has 4addr mode already enabled.
This operation would not have been necessary in the first place and this
failure results in disconnecting, e.g., when roaming from one backhaul
BSS to another BSS with Multi AP.
Avoid this issue by ignoring the nl80211 command failure in the case
where 4addr mode is being enabled while it has already been enabled.

There's a chance that prior to config reload being requested a scan work
was started. As such forcing wpa_supplicant to WPA_DISCONNECTED was
removing any hints that the actual driver is busy with work. That led to
wpa_supplicant reporting "Failed to initialize AP scan" over and over
again for a few seconds (depending on driver/capabilities) until the
untracked scan finished.
Cancelling a scan isn't really a solution because there's a bunch of
scanning state bits sprinkled across wpa_supplicant structure and they
get updated as driver events actually flow in in async manner.
As far as I can tell this is only preventing unnecessary warning
messages. This doesn't seem like it was crippling any logic per se.

The chirp scan could override the scan_res_handler. This could lead to
wpa_supplicant getting stuck in a scanning state while not scanning at
all until forced to, e.g., via an explicit SCAN control command.
The condition for trigerring this problem in my testing was when
(interface_count % 3) == 2. This introduced a two second delay before
actual scan was triggered after starting the wpa_supplicant instance up.
If DPP chirping was requested fast enough, in between the queueing and
triggering, it would punt the scan request, never to be resumed again.
Chirp scan handler wouldn't resume it leaving wpa_supplicant
inadvertently idle.

hostapd was already exposing this. There's no reason not to expose it in

The Authentication Request frames triggered by the reception of a
Presence Announcement frame were sent to the broadcast address. This is
not correct behavior since the source MAC address of the Presence

and one for 6 GHz channels. Since hw_get_chan() checks all the
