97236cee6a WPS: Skip rescanning after provisioning if AP was configured
If WPS provisioning step is completed with an AP that is in WPS
configured state, we can skip a second scan after the provisioning step
since the AP is unlikely to change its configuration in such a case.
This can speed up WPS connection a bit by removing an unneeded scan.

4342326fc7 Add ignore_old_scan_res configuration parameter
This can be used to configure wpa_supplicant to ignore old scan results
from the driver cache in cases where such results were not updated after
the scan trigger from wpa_supplicant. This can be useful in some cases
where the driver may cache information for a significant time and the AP
configuration is changing. Many such cases are for testing scripts, but
this could potentially be useful for some WPS use cases, too.

407be00b6c P2P: Postpone P2P scan only if station mode scan is pending
sta_scan_pending was supposed to be accurate enough for determining
whether a P2P scan needs to be postponed. However, it has turned out
that there were cases where sta_scan_pending was not cleared properly.
While the known cases have now been addressed, it is possible that some
other cases may still exist. To avoid issues with P2P operationg getting
stuck, verify more carefully that there is a real pending station mode
scan (either in progress or scheduled to be requested).

cfd31b5026 Use special scan result processing steps only on requesting interface
Scan result events are shared between all virtual interfaces sharing the
same radio. However, some of the steps are not really appropriate on

b1cd021e29 P2P: Re-start P2P operation if station mode scanning is stopped
There were couple of code paths that could end up stopping station mode
scanning without clearing sta_scan_pending. This could result in P2P
search getting stuck waiting for completion of station mode scan which
would never show up. Fix this by calling wpas_p2p_continue_after_scan()
in cases where station mode scans are stopped. This allows
sta_scan_pending to be cleared and P2P search operation continued.

b277a2bebc P2P: Allow shared interface channel preference to be ignored
p2p_ignore_shared_freq=1 in the configuration file (or "SET
p2p_ignore_shared_freq 1" on control interface) can now be used to
configure wpa_supplicant to ignore the preference on shared operating
channel when the driver support multi-channel concurrency. The default
behavior is to try to start any new P2P group on an operating channel
that is already in use on another virtual interface to avoid extra cost
from hopping between multiple channels. If this new parameter is set to
1, such preference is not used and instead, the channel for the new P2P
group is selected based on other preferences while ignoring operating
channels of any concurrent connection.

the currently used operating channel on a virtual interface that is

aware of the shared channel and using that preference as the highest
priority when re-selecting the channel during negotiation.

77e4e85321 P2P: Mark peer authorized for persistent group invitation
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

cd1e2309a2 P2P: Indicate frequency for upper layer invitation processing

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.

c5f10e804a Use more accurate timestamps for scan results
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
fetching the results from the driver and then using that value to
calculate the time when the driver last updated the BSS entry. In
addition, more debug information is added for P2P peer updates to be
able to clearly see how old information is being used here.

ec01d5f6b0 P2P: Avoid concurrent scans during all steps of group formation
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.

77dfafd07d P2P: Cancel group formation timeout on group removal (on client)
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.

d1ec319f12 Interworking: Continue ANQP fetch after TX failure
If the driver rejected any of the offchannel Action frame TX requests,
the previous implementation terminated ANQP fetch process. While the
driver should not really reject the request normally, it is possible
that a request gets rejected for some reason. Allow the fetch process to
continue with the next AP in such case to avoid breaking networking
selection. This could result, e.g., in auto_interworking=1 process
failing to connect if any the driver rejects requests to any of the APs
in the scan result even if some other APs provided suitable information.

3ab35a6603 Extend EAPOL frames processing workaround for roaming cases
Commit 1ff733383f added a mechanism to
work around issues due to association events and EAPOL RX events being
getting reordered. However, this applied only for the case where
wpa_supplicant is not in associated state. The same issue can happen in
roaming case with drivers that perform BSS selection internally (or in
firmware). Handle that case similarly by delaying received EAPOL frame
processing if the source address of the EAPOL frame does not match the
current BSSID.

Since wired IEEE 802.1X do not have BSSID, make this additional
workaround conditional on BSSID match having been observed during the
previous association.

This fixes issues where the initial EAPOL frame after reassociation was
either dropped (e.g., due to replay counter not increasing) or replied
to with incorrect destination address (the BSSID of the old AP). This
can result in significantly more robust roaming behavior with drivers
that do not use wpa_supplicant for BSS selection.

d49ea68284 Android: Force group access to ctrl_iface directory
wpa_supplicant is started from /init.*.rc on Android and that seems
to be using umask 0077 which would leave the control interface
directory without group access. This breaks things since Wi-Fi
framework assumes that this directory can be accessed by other
applications in the wifi group. Fix this by adding group access even
if umask value would prevent this.

In most cases, this issue was not hit since the control interface
directory is normally created by that same init.*.rc file with suitable
mode and wpa_supplicant is killed in the way that does not allow it to
remove the file. However, if wpa_supplicant is allowed stop cleanly, it
will remove the directory and the next start could result with the Wi-Fi
framework not being able to use Wi-Fi (and GUI not showing Wi-Fi getting
enabled).

175171ac6c P2P: Retry PD Request in join-a-running-group case
The GO may be in sleep when we send a PD Request frame to indicate that
we are about to join a running group. Previously, this frame was not
retried more than normal low level retries. This can result in the GO
not getting the frame especially in cases where concurrent multi-channel
operations or aggressive sleep schedule is used since most drivers do
not yet synchronize with the GO's NoA before association.

Increase the likelihood of the GO receiving the PD Request frame by
retransmitting it similarly to the PD-for-GO-Negotiation case. Start
the actual join operation only after these retries have failed to get
an acknowledgment from the GO to give the connection attempt a chance
to succeed if the driver implements better NoA synchronization for it.

So I have reduced some steps.

I could boot a GO by this command sequence.
-------------
add_net
set_network 0 ssid '"DIRECT-XX"'
set_network 0 psk
'"123456789012345678901234567890123456789012345678901234567890123"'

set_network 0 pairwise CCMP
set_network 0 auth_alg OPEN
set_network 0 mode 3
set_network 0 disabled 2
p2p_group_add persistent=0 freq=2412
-------------

By this sequence, pbkdf2_sha1() was called three times and the function
calculates the same value each time. Reduce number of calls to
pbkdf2_sha1() from 3 to 1 by caching the previous result.

45ac5793fc new_dbus_handlers: Clear errno
There are a few instances where dbus handlers test the value
of errno to test whether strtoul completes successfully.
Since strtoul does not clear errno, and there's no strong
reason to suspect that errno is already clear, it is safer
to clear it right before calling strtoul.  Also, any failure
in strtoul (setting errno non-zero) should be considered a
failure.

While testing using dbus-send, I found that a malformed
network path can cause a crash due to net_id being left
NULL.  We should test for this before calling strtoul
on it.

Tested with:

dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply \

42d235477f Use wpa_drv_{disassociate,deauthenticate} while waiting for connection
wpa_supplicant_{disassociate,deauthenticate}() need to inform the driver
about decision to disconnect even if this happens during the time when
the driver is still trying to complete association. During that time,
wpa_s->bssid is not set, so the code in these functions needs to figure
out the correct BSSID based on that field or wpa_s->pending_bssid. In
addition, it is possible that the BSSID is not even known at
wpa_supplicant at this point in time when using drivers that perform BSS
selection internally. In those cases, the disconnect command needs to be
sent to the driver without the BSSID.

This fixes issues where the driver (or cfg80211 in particular) may be
left in mismatching state with wpa_supplicant when disconnection (e.g.,
due to a ctrl_iface command) happens between connection request and
association event.

10737aba22 Handle assoc reject events without wpa_supplicant SME
If the driver indicates the association (or authentication) was
rejected, wpa_supplicant should handle this connection failure similarly
to other cases. Previously, this was only handled with drivers that use
wpa_supplicant SME.

In case of cfg80211-based drivers, a rejected association was actually
already handled since cfg80211 generates a deauthentication event after
indicating connection failure. However, rejected authentication resulted
in wpa_supplicant waiting for authentication timeout to expire which is
unnecessary long wait.

Fix this by calling wpas_connection_failed() to use the common mechanism
to reschedule a new connection attempt with the previously attempted
BSSID blacklisted.

Commit 0d30cc240f forced

Fix this by making wpas_p2p_is_client() default to client case if

GO mode operation would not really clear the pointer without explicit

13ece96f70 P2P: Improve robustness against lost ctrl::ack frames
P2P includes two use cases where one of the devices is going to start a
group and likely change channels immediately after processing a frame.
This operation may be fast enough to make the device leave the current
channel before the peer has completed layer 2 retransmission of the
frame in case the ctrl::ack frame was lost. This can result in the peer
not getting TX status success notification.

For GO Negotiation Confirm frame, p2p_go_neg_conf_cb() has a workaround
that ignores the TX status failure and will continue with the group
formation with the assumption that the peer actually received the frame
even though we did not receive ctrl::ack. For Invitation Response frame
to re-invoke a persistent group, no such workaround is used in
p2p_invitation_resp_cb(). Consequently, TX status failure due to lost
ctrl::ack frame results in one of the peers not starting the group.

Increase the likelihood of layer 2 retransmission getting acknowledged
and ctrl::ack being received by waiting a short duration after having
processed the GO Negotiation Confirm and Invitation Response frames for
the re-invocation case. For the former, use 20 ms wait since this case
has been worked around in deployed devices. For the latter, use 50 ms
wait to get even higher likelihood of getting ctrl::ack through since
deployed devices (and the current wpa_supplicant implementation) do not
have a workaround to ignore TX status failure.

20 ms is long enough to include at least couple of retries and that
should increase likelihood of getting ctrl::ack through quite a bit. The
longer 50 ms wait is likely to include full set of layer 2 retries.

7a808c7eb7 P2P: Allow P2P functionality to be disabled per interface
By default, P2P is enabled globally for all virtual interfaces and this
makes wpa_supplicant include WSC and P2P IEs in Probe Request frames for
all scans even if this is for a non-P2P station connection to speed up
device discovery. If an interface is dedicated for non-P2P station mode
operations, it is now possible to disable addition of WSC and P2P IEs
into Probe Request frames with a per-interface p2p_disabled parameter.
This can be set either in the configuration file (p2p_disabled=1) or at
run time ("wpa_cli -i wlan0 set p2p_disabled 1"). Unlike the previous
mechanism ("wpa_cli p2p_set disabled 1"), the new parameter changes the
behavior only for the specified interface while other interfaces
continue to follow the global P2P enabled/disabled state.

initial scan from the first P2P_FIND command has completed,
sta_scan_pending may be left set without an automatic way of getting it

Fix this by clearing the sta_scan_pending flag whenever station mode scans
are stopped due to no enabled networks resulting in INACTIVE mode getting
entered. In addition, avoid setting sta_scan_pending flag when a special

c244dd2ec0 P2P: Fix PSK configuration for GO network
Setting just ssid->passphrase is not enough to complete the network
block for the GO entry. Also the PSK needs to be derived so that the
network is considered enabled by wpas_network_disabled(). The previous
version worked as long as something else allowed the scan request to be
performed (this is needed even though the actual scan is skipped when
starting GO).

The first GO start was allowed because wpa_s->scan_req is initialized to
1 in wpa_supplicant_alloc(). However, other attempts may fail if
wpa_s->scan_req is cleared. This failure shows up as "No enabled
networkas - do not scan" in debug log followed by state change to
INACTIVE when trying to start GO.

terminating the group.

Fix this by relaxing network block matching rules when figuring out

network blocks are removed once the P2P group is terminated.

the wpa_supplicant_mark_disassoc() call is in the second part, the above
mentioned issues are resolved. In addition, this cleans up the P2P group
interface removal case by not trying to use fast reconnection mechanism
just before the interface gets removed.

6f1ca696c7 P2P: Do not fail p2p_group_remove just based on current_ssid
The wpa_s->current_ssid pointer may get cleared, e.g., when
disconnected. Commit 30ee769235 made
wpas_p2p_group_delete() exit early before removing a P2P interface in
this type of case. That can cause number of issues from p2p_group_remove
command failing to busy loop when terminating wpa_supplicant if there is
a P2P group interface in client mode and that interface happens to be in
disconnected state. Fix these issues by allowing wpas_p2p_group_delete()
remove the P2P group interface regardless of whether wpa_s->currnt_ssid
is set.
