The overlap condition cannot disappear before group formation timeout
hits, so there is no point in continuing in this case and failure can
be indicated immediately.
This allows the pending group interface to be removed if we fail
to join a running group. A longer than 15 second timeout is needed
here since the GO may not have authorized our connection yet.
A new ctrl_interface command, WPS_CANCEL, can now be used to cancel
a pending or ongoing WPS operation. For now, this is only available
with wpa_supplicant (either in station or AP mode). Similar
functionality should be added for hostapd, too.
If an authorized (p2p_connect used locally) GO Negotiation is
rejected when receiving GO Negotiation Request from the peer,
indicate the failure with a ctrl_interface P2P-GO-NEG-FAILURE
event. Previously, this event was only shown on the peer (i.e.,
the device receiving the GO Negotiation Response with non-zero
Status code).
Since this message now includes P2P Device Info attribute, it is
reasonable to learn the peer data and process the message instead of
rejecting the message.
Add (or complete Probe Request only) P2P peer entry when receiving
Provision Discovery Request from a previously unknown peer. This is
especially of use for a GO when a P2P client is requesting to join
a running group.
The scan operation before Provision Discovery Request may not include
the GO. However, we are likely to have the GO in our P2P peer table,
so use that information to figure out the operating channel if BSS
table entry is not available.
This should not really happen, but it looks like the Listen command
may fail is something else (e.g., a scan) was running at an
inconvenient time. As a workaround, allow new Extended Listen
operation to be started if this state is detected.
The previous version had a bug that could result in NULL pointer
dereference if the P2P IE included Manageability attribute, but no
Capability attribute.
This can happen, e.g., when a P2P client connects to a P2P group
using the infrastructure WLAN interface instead of P2P group
interface. In that case, the P2P client may behave as if the GO
would be a P2P Manager WLAN AP.
This is needed to make sure we do not try to accidentally enable GO
in channels that may not be allowed. In addition, this may help with
some driver that do not like channel 14 even as a passive scan
channel.
This command is supposed to return the PIN value that was generated
or passed in as an argument. In the AP case, the entered PIN was not
being returned.
This is needed to be able to change parameters for dynamically
created interfaces between the creation of the interface and
association/start AP commands.
Following ctrl_interface commands can now be used:
P2P_SET client_apsd disable
- disable configuration (i.e., use driver default) in client mode
P2P_SET client_apsd <BE>,<BK>,<VI>,<VO>;<max SP Length>
- enable UASPD with specific trigger configuration (0/1) per AC
(max SP Length is currently ignored)
P2P_SET go_apsd disable
- disable configuration (i.e., use driver default) in AP mode
P2P_SET go_apsd <0/1>
- disable/enable APSD in AP mode
P2P specification v1.15 fixed the description of the GAS fragmentation
to not duplicate NQP Query Response Field header in all fragments. This
change makes the fragmentation match with the description in IEEE
802.11u. The change is not backwards compatible with previous P2P
specification versions as far as fragmented SD responses are concerned.
This event indicates the Device Password ID that the peer tried
to use in GO Negotiation. For example:
P2P-GO-NEG-REQUEST 02:40:61:c2:f3:b7 dev_passwd_id=4
If enabled, cross connection allows GO to forward IPv4 packets
using masquerading NAT from the P2P clients in the group to an
uplink WLAN connection. This is disabled by default and can be
enabled with "wpa_cli p2p_set cross_connect 1" on the P2P device
interface.
When we receive Device Discoverability Response, we need to initiate
new GO Negotiation as quickly as possible to avoid the target client
from going back to sleep. Make sure we do not end up in
P2P_CONNECT_LISTEN state (short Listen mode) in this case.
For now, this applies to the test command that can be used to set
periodic NoA (p2p_set noa). The value are stored and periodic NoA
is enabled whenever there are no non-P2P STAs connected to the GO.
While this is not strictly speaking required by the P2P specification
for a not-P2P Managed Device, this can provide useful information for
the P2P manager AP and may be needed to pass certification tests.
