Commit 50285f5ca8 ended up forcing channel
re-selection in number of cases where the peer would actually have
accepted our initial preference. Fix the parts related to best channel
information by using best_freq_overall as the highest priority and by
skipping the band changes if the peer supports the channel that we
picked since these were based on the assumption that
p2p_reselect_channel() is called only if the peer could not accept our
initial choice which is not the case anymore.

Commit 79879f4ae8 enabled all channels to
be used when negotiating channel with a driver that supports
multi-channel concurrency. Extend that to cover cases where the channel
is not being negotiated (e.g., p2p_group_add to start a GO).

If the previously started setup is terminated in case both peers
initiate TDLS link at more or less the same time, disable the old link
to allow the dummy station entry to be deleted from cfg80211 so that a
new entry can be added for the setup direction that will be allowed to

Add NL80211_CMD_UPDATE_FT_IES to support update of FT IEs to the
WLAN driver. Add NL80211_CMD_FT_EVENT to send FT event from the
WLAN driver. This will carry the target AP's MAC address along
with the relevant Information Elements. This event is used to
report received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).

It is possible for a P2P client to connect to an operating group without
exchanging any Probe Request/Response frames that would allow the GO to
discover the peer. To make sure there is a P2P peer entry at the GO, try
to add the peer information based on P2P IE in (Re)Association Request
frame.

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.

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.

It is clearer to keep all the validation steps described in IEEE 802.11
11.3.5.4 in a single location instead of splitting this between the
parsing and processing functions.

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.
