Sunil Dutt 6b947db103 P2P: Remove PD-before-join-timeout mechanism
The PD Request retry limit can be used to achieve the same behavior,
so drop this duplicated timeout mechanism and control the timeout
based on MAX_PROV_DISC_REQ_RETRIES.

Jouni Malinen 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.

Masashi Honma 30c371e8a5 P2P: Reduce redundant PSK generation for GO
The PSK generation done by pbkdf2_sha1() is one of the longest CPU time
users according to our profiling from boot to GO started.

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.

Paul Stewart 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 \

Jouni Malinen 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.

Jouni Malinen 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.

The new P2P_SET parameter disc_int can now be used to configure
discoverable interval for p2p_find operations. The format of the command

first two parameters are given in units of 100 TUs (102.4 ms). The third
parameter can be used to further limit the interval into a specific TU
amount. If it is set to -1, no such additional limitation is enforced.
It should be noted that the P2P specification describes the random
Listen state interval to be in units of 100 TUs, so setting the max TU
value to anything else than -1 is not compliant with the specification
and should not be used in normal cases. The default parameters can be
set with "P2P_SET disc_int 1 3 -1".

Commit 0d30cc240f forced
wpa_s->current_ssid to be cleared in wpa_supplicant_mark_disassoc()

timeout in that case if the interface is not recognized as a client
interface (which was based on wpa_s->current_ssid being set).

Fix this by making wpas_p2p_is_client() default to client case if
wpa_s->current_ssid is NULL. This is much more likely case since the P2P
GO mode operation would not really clear the pointer without explicit
request to disconnect.

Jouni Malinen 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.

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

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

Jouni Malinen 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.

Fix this by deriving PSK from the passphrase for GO mode.

terminating the group.

Fix this by relaxing network block matching rules when figuring out

network blocks are removed once the P2P group is terminated.

Jouni Malinen eb7719ff22 Add support for using GCMP cipher from IEEE 802.11ad
This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.

This commit does not included changes to WPS or P2P to allow GCMP to be
used.

The new gas_request and gas_response_get commands can be used to request
arbitary GAS queries to be performed. These can be used with ANQP or

gas_request <BSSID> <AdvProtoID> [Query]

For example, ANQP query for Capability list in interactive wpa_cli
session:

> gas_request 02:00:00:00:01:00 00 000102000101
<3>GAS-RESPONSE-INFO addr=02:00:00:00:01:00 dialog_token=0

It should be noted that the maximum length of the response buffer is
currently 4096 bytes which allows about 2000 bytes of the response data
to be fetched with a single gas_response_get command. If the response is
longer, it can be fetched in pieces as shown in the example above.

There is no need to mandate admission control (ACM=1) by default, so
clear that flag in the case the configuration file does not specify
wmm_ac_{vo,vi}_acm value. This gets closer to the values mentioned

Masashi Honma 0a0c38f63d Do not proceed with association if get_bssid() returns failure
This is the normal flow for association:

wpa_supplicant <--(EVENT_ASSOC event )--  device driver
wpa_supplicant  --( get_bssid()      )--> device driver
wpa_supplicant <--( return BSSID     )--  device driver

However, a device driver could return EINVAL for get_bssid() because it
recognizes it has already been disconnected. When the wpa_supplicant
received EINVAL, the bssid field could be used uninitialized in the
following flow:

wpa_supplicant <--(EVENT_ASSOC event )--  device driver
                                          device driver (receive deauth)
wpa_supplicant  --( get_bssid()      )--> device driver
wpa_supplicant <--( return EINVAL    )--  device driver

Prevent this by requiring the get_bssid() call to succeed when
processing association events.

Eyal Shapira 462a7439e1 Add p2p_go_max_inactivity config option
This enables setting a different max inactivity timeout for P2P GO.
This timeout is used to detect inactive clients. In some scenarios
it may be useful to have control over this and set a shorter timeout
than the default 300s. For example when running STA and P2P GO interfaces
concurrently, the STA interface may perform scans which may cause the
GO to miss a disassoc / deauth frames from a client and keep assuming
that the client is connected until the inactivity detection kicks in.
300 secs is a bit too long for such scenarios and creates a bad user
experience.

Tomasz Bursztyka 7c865c6853 Add automatic scanning support
Like bgscan, autoscan is an optional module based feature to automate
scanning but while disconnected or inactive.

Instead of requesting directly a scan, it only sets the scan_interval
and the sched_scan_interval. So, if the driver supports sched_scan,
autoscan will be able to tweak its interval. Otherwise, the tweaked
scan_interval will be used. If scan parameters needs to be tweaked, an
autoscan_params pointer in wpa_s will provide those. So req_scan /
req_sched_scan will not set the scan parameters as they usually do, but
instead will use this pointer.

Modules will not have to request a scan directly, like bgscan does.
Instead, it will need to return the interval it wants after each
notification.

if either a Probe Request or Probe Response frame is lost. Improve
robustness by assuming the peer is still operating the GO and starting
the join operation. If the GO is not found during PD-for-join or the
single-channel scans during the join, fall back to GO Negotiation.

Jouni Malinen fea7c3a055 Ignore network blocks that have invalid WEP key length
Do not try to associate with a network that has an invalid or incomplete
configuration because the association or at least data connection would
fail anyway. This commits adds a common function for checking whether a
network block is disabled to make it easier to check network blocks
without having to reject them during configuration file parsing (which
would prevent wpa_supplicant from starting). The only additional check
added in this commit is to verify the WEP key length. Similar checks for
other parameters can be added in future commits.

When forming a P2P group using WSC PIN method, if the PIN is entered
incorrectly the P2P client supplicant instance will crash as a result
of cleanup happening on data that is still in use in a case where a
separate P2P group interface is used.

For example, here is the path for the first crash:
eap_wsc_process():
- creates struct wpabuf tmpbuf; on the stack
- sets data->in_buf = &tmpbuf;
- calls wps_process_msg()
- which calls wps_process_wsc_msg()
- which, in case WPS_M4: calls wps_fail_event()
- which calls wps->event_cb()
- wps->event_cb = wpa_supplicant_wps_event()
- wpa_supplicant_wps_event()
- wpa_supplicant_wps_event_fail()
- which calls wpas_clear_wps()
- which calls wpas_notify_network_removed()
- which calls wpas_p2p_network_removed()
- which calls wpas_p2p_group_formation_timeout()
- which calls wpas_group_formation_completed()
- which calls wpas_p2p_group_delete()
- which calls wpa_supplicant_remove_iface()
- which calls wpa_supplicant_deinit_iface()
- which calls wpa_supplicant_cleanup()
- which calls eapol_sm_deinit()
- ... which eventually uses the ptr data->in_buf to free tmpbuf, our
stack variable and then the supplicant crashes

If you fix this crash, you'll hit another. Fix it and then a segfault.
The way we're cleaning up and deleting data from under ourselves here
just isn't safe, so make the teardown portion of this async.

For concurrency scenarios we should not update the scan results without
P2P IE to P2P group interfaces. This patch is to take care if a scan has
been requested on STA interface and scan results are getting updated
from sibling to P2P group interface. A P2P GO Probe Response for a
legacy STA scan would be without P2P IE. So it will wrongly update the
BSS list of P2P group interface too when results are updated from
sibling.

Since P2P group interfaces are used only for connecting to a P2P group,
it is fine to filter out all non-P2P entries from their BSS table.

My next patch will also require knowing the signal strength of probe
requests throughout the code (where available), so add it to the
necessary APIs.

Mukesh Agrawal c6e86b63d2 Create DBus getter/setter for ScanInterval
Enable control of wpa_s->scan_interval via D-Bus. This parameter
controls the delay between successive scans for a suitable AP.

Also, update dbus.doxygen with ScanInterval, and some other
parameters that were undocumented.

Nirav Shah 024d018b55 Clean up: Replace standard lib methods with os.h ones
Some of the standard lib functions being used directly are redefined in
src/utils/os.h thus providing an abstraction. Change code to use os_*
functions instead of directly using the lib functions.

Johannes Berg 4f68895e92 debug: Add option to log to Linux tracing
Add the option (-T) to wpa_supplicant to log all debug messages into the
kernel tracing, allowing to aggregate kernel debugging with
wpa_supplicant debugging and recording all with trace-cmd.

Since tracing has relatively low overhead and can be filtered
afterwards, record all messages regardless of log level. However, it
will honor the -K option and not record key material by default.

Jouni Malinen 21d996f775 P2P: Add support for preferred channel list
p2p_pref_chan configuration parameter can now be used to set the
list of preferred channel for P2P GO Negotiation. This will be used
in the priority order if the peer does not support the channel we
are trying to use as the GO (configured operating channel or the
best 2.4 GHz/5 GHz channel) for the case where a forced channel is
not used.

p2p_pref_chan=<op class:channel>,...

For example:
p2p_pref_chan=81:1,81:2,81:3,81:4,81:5,81:6

This would configure 2.4 GHz channels 1-6 as the preferred ones with
channel 1 the most preferred option.

These configuration parameters can be set in wpa_supplicant.conf and
dynamically updated with "wpa_cli set <param> <value>".
