The code was iterating all the interfaces, and for each interface
iterated all the network blocks to count active P2P GO and P2P Client
interfaces.
Change the code to reuse wpas_p2p_get_go_group() to get a P2P GO
interface and add wpas_p2p_get_cli_group() and use it to find a
P2P Client interface, and use these objects when evaluating the
group capability.

Re-factor wpas_p2p_get_go_group() to:
1. Skip the dedicated P2P Device management interface if it is used.
2. Instead of iterating all the interface configured networks,
only access the current_ssid pointer to check if the current
interface is acting as a persistent P2P GO.
To avoid code duplication, also re-factor wpas_p2p_group_go_ssid()
to call wpas_p2p_get_go_group().

Add a test case verifying deferred P2PS provision discovery when an
advertiser sends the status 11 (Fail: reject by user) in the follow-on
PD Request.
Signed-off-by: Max Stepanov <Max.Stepanov@intel.com>
When a follow-on PD request is received, peer should not send a
follow-on PD response except the case when the PD request status value
is 12 (Success: accepted by user). Previously, the wpa_supplicant
implementation behaved differently sending the follow-on PD Response on
any follow-on PD Request.
Fix the issue by adding the following changes:
1. Don't send PD Response if the follow-on PD Request status is
different than 12 (seeker side).
2. Don't wait for the follow-on PD Response if the follow-on PD
Request was sent with the status different than 12 (advertiser
side).
3. If the follow-on PD Request was sent with the status different
than 12 use the follow-on PD Request ACK as PD completion event
(advertiser side).
4. Notify ASP about the PD completion by sending P2PS-PROV-DONE with
the PD Request status (advertiser side).

Not doing so may result in a deferred PD flow failure (currently the
hwsim tests succeeded because seeker never stopped find, spending enough
time listening, so the follow-on PD would succeed).
Fix this by calling p2p_ext_listen when the seeker receives a deferred
PD failure event. Cancel extended listening when PD is done and also
stop find when seek is done.

It is expected that p2p_flush() should stop any ongoing p2p operation.
However, this was not the case with extended listen which was not

The new hostapd configuration parameter anqp_elem can now be used to
configure arbitrary ANQP-elements for the GAS/ANQP server. In addition
to supporting new elements, this can be used to override previously
supported elements if some special values are needed (mainly for testing
purposes).
The parameter uses following format:
anqp_elem=<InfoID>:<hexdump of payload>
For example, AP Geospatial Location ANQP-element with unknown location:
anqp_elem=265:0000
and AP Civic Location ANQP-element with unknown location:
anqp_elem=266:000000

This allows wpa_supplicant to expose internally unknown ANQP-elements in
the BSS command. For example, "ANQP_GET <BSSID> 265" can be used to
fetch the AP Geospatial Location ANQP-element and if the AP has this
information, the "BSS <BSSID>" command will include the response as
"anqp[265]=<hexdump>".

This ensures that group key is set as long as the interface exists.
Additionally, ifconfig_up is needed as wpa_group will enter

Some operations like a new scan result processing can result in large
number of wpa_supplicant control interface messages being generated.
Especially with multiple control interface monitors, this could result
in hitting the output queue length maximum and event messages getting
dropped. In worst case, that could even result in hitting ten
consecutive sendto() errors which could result in an attached monitor
socket getting detached.
Avoid this type of issues by throttling monitor event transmission based
on the output queue length. If more than half of the maximum send buffer
is used, postpone sending of following event messages until the pending
output queue has dropped below the limit.

The hostapd_hw_get_channel() function can't be used to convert center
frequencies to channel numbers, because the hw mode lists don't have all
the center frequencies. The hw mode lists have the main channel
frequencies and flags to indicate the channel topography.
For instance, channel 5805 with VHT80- has the channel center frequency
segment 0 at 5775. This segment is only indicated indirectly in the hw
mode list by the HOSTAPD_CHAN_VHT_50_30 flag. The hw mode list doesn't
have any elements with frequency 5775 to allow the conversion to a
channel number. Thus, we need to use ieee80211_freq_to_chan() instead.

wpas_p2p_move_go_csa() uses wpas_p2p_init_p2p_params() to select the
frequency to move to. However, it is possible that all the channels are
already used, so the selection of a new frequency would fail, although
the frequency used by the P2P GO should not be considered as used if it
is the only one using it.
To overcome this, allow the frequency selection to continue even if all
the frequencies are in use, but the frequency used by the P2P GO is not
used by any station interface.
