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.

Add support for VHT capability overrides to allow testing connections
with a subset of the VHT capabilities that are actually supported by
the device. The only thing that isn't currently supported (by mac80211
and this code) is the RX/TX highest rate field.

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
since we are going to start from beginning. Thos avoids starting sched
scan from prev_sched_ssid after scanning the full list, in case of
adding a network to ssid during scheduled scan.

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
be run. In this case, go back to the initial values.

The peer commit element needs to be validated to pass one of the steps
listed in IEEE 802.11, 11.3.5.4:
scalar-op(r, ELEMENT) = 1 modulo p
Similar step was present for ECC groups, but was missing for FFC groups.
This is needed to avoid dictionary attacks.
Thanks to Michael Roßberg and Sascha Grau for reporting this.

11.3.5.4 in a single location instead of splitting this between the

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
Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
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.

Peer device includes its list of allowed operating channels in the
Invitation Response frame. When we are becoming the GO, use that list

When re-invoking a persistent group in P2P client role, the new
pref=<MHz> parameter can now be used with the p2p_invite command to
indicate a preferred operating frequency. Unlike the older freq=<MHz>
parameter, this leaves GO an option to select another channel (from our
supported channels) if the GO cannot accept the channel.

Commit fb8984fd6f cleared wps_method to
WPS_NOT_READY in p2p_stop_find_for_freq() as an attempt to clear
authorization when a group formation is cancelled. However, this code
path is hit also in cases where the user did not actually cancel
anything (e.g., from p2p_process_go_neg_req()). As such, it is not fine
to clear wps_method here even if it could be proper for some cases. For
now, revert that part to avoid regressions and consider clearing
wps_method on cancel separately.

In case we have replied to a peer's GO Negotiation Request frame with a
GO Negotiation Response frame using status code
info-currently-unavailable (1), the peer is likely going to wait for us
to initiate GO Negotiation on its Listen channel. We were previously
using alternativing send-GO-Neg-Req and Listen phase when providing that
response after the user had authorized the connection. However, the
Listen phase here is unnecessary in this case and will make the
connection take longer time to go through. Skip the Listen phase and
make the wait-for-GO-Neg-Resp timeout random between 100 and 200 ms to
avoid getting in sync with the peer. In practice, this will make us
retry GO Negotiation Request frames more frequently and remain on the
peer's Listen channel for most of the time when initiating GO
Negotiation after status=1 response.

There may be environments in which large number of devices are operating
on the social channels. In such cases, it is possible for the Action
frame TX operation wait for quite long time before being able to get the
frame out. To avoid triggering GO Negotiation failures, increase the
timeouts for GO Neg Req (with TX ACK) and GO Neg Resp (with or without
TX ACK as long as status=0) to 500 ms.
