Commit 77dfafd07d cancels group formation
timeout on group removal case but failed to reset the
p2p_in_provisioning flag. This can lead to repeated p2p_find failures if
the group gets removed before completion of the WPS provisioning step
(e.g., GO tears down the group). Fix this by clearing
p2p_pin_provisioning when cancelling group formation.

The unprotected disconnection events were previously processed only for
drivers that used the wpa_supplicant SME implementation (separate
authentication and association commands). However, this can be useful
for drivers that use the connect API, so remove the limitation and allow
the same IEEE 802.11w SA Query mechanism to be used even without full
use of the wpa_supplicant SME.

Instead of using atoi(), use strtol() which allows checking if
the configuration values are valid integers and can understand
more than just decimal (also hexadecimal and octal). This not
only allows specifying some fields in hex (which can be useful)
but also rejecting invalid configurations, e.g.,
disassoc_low_ack=27 * 2
which was previously read as just 27.

If the whole ssid list was scanned, don't save the prev scheduled ssid

In case that the ssid list is longer than max number of ssids,
ths scheduled scan aborted after timeout and rescheduled again
with shorter timeout and longer interval. In case that the timeout
is shorter than the interval, only one scan iteration will

When p2p_invite persistent=<id> is used to request a persistent group to
be re-invoked, the peer may reply with status=1 (info not yet available)
if upper layer processing of the invitiation is requested. The peer is
ten expected to start another invitation exchanged within 120 seconds if
the user authorizes the connection. Allow this process to be used more
easily by automatically authorizing the peer that we tried to invite to
use this second invitation sequence even if persistent_reconnect=0.
For this mechanism to work, the device that starts the invitation needs
to start listen mode to be able to receive the invitation request from
the peer. At least for now, this is not done automatically, but future
changes could potentially enable this automatically at least if there
are no concurrent operations in progress.
Example sequence on the initiator:
cmd: P2P_INVITE persistent=1 peer=<addr>
event: P2P-INVITATION-RESULT status=1
cmd: P2P_LISTEN 120
wait for peer to start another invitiation round.. group will be
re-invoked automatically
On the peer (with persistent_reconnect=0):
event: P2P-INVITATION-RECEIVED sa=<addr> persistent=1 [freq=<MHz>]
wait for user approval
cmd: P2P_INVITE persistent=1 peer=<addr>
group will be re-invoked automatically

When a device that is a GO in a persistent group receives an Invitation
Request from a P2P client and persistent_reconnect=0, upper layer is
notified of this with P2P-INVITATION-RECEIVED event. The upper layer is
supposed to run another invitation exchange is this case, but if that
does not happen and the GO is started without successful (status=0)
invitation exchange, the operating channel for the group may end up
getting set in a way that the P2P client is not able to support. Provide
optional freq parameter in the P2P-INVITATION-RECEIVED event on the GO
side. If this parameter is received and the upper layer decides to issue
P2P_GROUP_ADD command, that command should include this freq parameter
to make sure the operating channel gets selected from the set that the
peer can support.

beacon_int (in TU) can now be used to configure Beacon interval for AP
mode operations (including P2P GO) in wpa_supplicant. This can be set
either in a network block or as a global parameter in the configuration
file (or with "SET beacon_int <value>" control interface command) to
apply for all networks that do not include the beacon_int parameter to
override the default.
In addition, this commits extends the dtim_period parameter to be
available as a global parameter to set the default value. dtim_period is
now stored in the configuration file, too, if it was set.

When re-invoking a persistent group in P2P client role, the new

Previously, the credential to use for a connection with a specific BSS
was picked arbitrary based on first found match of each matching
mechanism. While the credential priorities were used elsewhere, this did
not take into account that different mechanisms could find multiple
matching credentials. As such, the highest priority credential was not
always used in case more than one credential matched with the selected
BSS. Fix this by checking credential priorities again during connection
request.

For various P2P use cases, it is useful to have more accurate timestamp
for the peer information update. This commit improves scan result
handling by using a single timestamp that is taken immediately after

addition, more debug information is added for P2P peer updates to be
able to clearly see how old information is being used here.

Previously, only some P2P states were considered to postpone concurrent
station mode scans during group formation. Especially the WPS
provisioning step was skipped due to issues to scans run on the P2P
client interface (see commit fc6997b345).
This is not ideal since a concurrent scan can slow down group formation
considerably and potentially make it time out. Enforce p2p-in-progress
through all steps of group formation on another interface to address
this.
Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
Group formation timeout is normally canceled when 4-way handshake is
completed (WPA_COMPLETED -> wpas_p2p_completed). However, it is possible
for the GO to stop the group before this happens (i.e., send
Deauthentication frame with reason code 3 before 4-way handshake is
completed). This resulted in the group getting removed, but the group
formation timeout left behind. The unexpected timeout may then result in
undesired termination of the following operation. Fix this by canceling
the group formation timeout in wpas_p2p_group_delete() similarly to how
group idle timeout was canceled there.
