9ec876662b P2P: Allow GO P2P Device Address to be used for scan result matching
This is a better way of matching P2P groups based on the unique P2P

50589751bf Interworking: Reject BSS based on disallow_aps
If a BSS is disallowed temporarily with disallow_aps, the network
connection is going to fail. As such, there is not much point in
allowing Interworking network selection to try to connect with such BSS.
As such, do not consider disallowed networks for automatic network
selection and reject requests to connect to them through
INTERWORKING_CONNECT.

6ede8a7e4d Interworking: Avoid duplicated network blocks
Do not add multiple network blocks for the same network from a single
credential. INTERWORKING_CONNECT used to generate a new network block
for each instance regardless of what network blocks have already been
configured. While this allows the connection to go through, it is not
efficient to leave behind potentially large number of network blocks
with the same contents (or worse, changed contents). Address this by
removing an older network block for the same credential before adding a
new one.

It was possible for the wpa_s->show_group_started and wpa_s->go_params
to be left set when a P2P group was removed before group formation had
completed. In case a separate P2P group interface was not used, this
could rsult in all future scans using the hardcoded DIRECT-* SSID and as
such, not find the network they were trying to find. Fix this by

731ca6364e Update regulatory change to all virtual interface for the phy
wpas_p2p_setup_channels function uses the per interface information
(wpa_s->hw.modes) for setting up the available channel list for P2P
operation, but if a separate P2P interface is used (e.g., p2p0 on
Android), the wpa_s instance for that interface may not get an updated
channel list. This can result in some operations, like "P2P_SET
disallow_freq", using old channel list information (e.g., world roaming
information with passive-scan/no-ibss flags) which was initialized
during the start-up. This could result in P2P functionality using
conflicting or obsolete channel information.

To resolve this issue, update channel list information on regulatory
change events to all of the virtual interfaces sharing the same phy for
which the event is received.

frame by confirming that the TX status payload matches the pending frame

d259249762 Fix ENABLE_NETWORK not to reconnect in disconnected state
DISCONNECT followed by ENABLE_NETWORK ended up starting a scan for a new
connection due to wpa_supplicant_enable_one_network() setting
wpa_s->reassociate = 1. This was done regardless of wpa_s->disconnected
being 1 which should imply that wpa_supplicant should not try to connect
before asked explicitly with REASSOCIATE or RECONNECT.

Fix this by making ENABLE_NETWORK setting of reassociate = 1 and
starting of scans for connection conditional on wpa_s->disconnected ==
0. This will make ENABLE_NETWORK trigger a connection only if
wpa_supplicant is already in a state where it would try to connect if
there are any enabled networks.

5079392954 Increase buffer size and prevent write beyond buffer end
wpa_config_write_key_mgmt has a buffer size of 50. This is not enough
to fit the longest case. I used a network with "WPA-PSK WPA-EAP
WPA-NONE" and CONFIG_IEEE80211R=y + CONFIG_IEEE80211W=y to produce
a string longer than 50 chars. Increase the buffer size to 100 to
prevent truncated output.

Truncated output is not the only problem. If the buffer end is
reached when adding certain key mgmt types the function does not
return immediately. This leaves pos > end. When a second os_sprintf
is called the calculation of end - pos yields a large positive
number for buffer size. End result is a write beyond the buffer end.
Fix this by bailing out if buffer end is reached.

ctrl_interface parameter can be used to initiate some control interface
backends, so simpler designs were not available for this.

The format of the new parameter is not exactly cleanest due to

ctrl_interface=....
no_ctrl_interface=

would end up with ctrl_interface=NULL.

25b65a142d Make sure updated BSS entry does not get added twice to the list
When the BSS table is being updated based on new scan results, a BSS
entry could end up getting added into last_scan_res list multiple times
if the scan results from the driver includes duplicated values. This
should not happen with driver_nl80211.c since it filter outs duplicates,
but in theory, other driver wrappers could indicate such scan results.
Anyway, it is safer to make sure this cannot happen by explicitly
verifying the last_scan_res list before adding an updated BSS entry
there. A duplicated entry in the list could potentially result in freed
memory being used if there is large enough number of BSSes in the scan
results to cause removal of old BSS entries.

a3cbf82e6d Fix possible freed-memory use in BSS table updates
If there are large number of BSSes in the scan results, BSS table update
could have added a BSS entry to the last_scan_res in a case where that
BSS entry got just deleted. This would happen only if there are more
than bss_max_count (by default 200) BSSes and if at least bss_max_count
of those BSSes are known (match a configured network). In such a case,
wpa_bss_add() could end up allocating a new BSS entry and return a
pointer to that entry even if it was the one that ended up getting freed
to keep the BSS table length within the limit. This could result in
freed memory being used and the process crashing (likely with segfault)
when trying to access information from that BSS entry.

Fix the issue by removing the oldest BSS entry before linking the new
entry to the table. This makes sure the newly added entry will never get
picked up as the one to be deleted immediately.

connection. This allows the GO to remove the group automatically if the

89286e91bf Re-open ctrl_iface socket on some failure cases as a workaround
If wpa_supplicant ctrl_iface clients are misbehaving and refusing to
read replies or event messages from wpa_supplicant, the single socket
used in wpa_supplicant to send messages can reach the maximum send
buffer limit. When that happens, no more responses to any client can be
sent. Work around this by closed and reopening the socket in case such a
failure state is detected. This is obviously not desirable since it
breaks existing connected sockets, but is needed to avoid leaving
wpa_supplicant completely unable to respond to any client. Cleaner fix
for this may require more considerable changes in the ctrl_iface design
to move to connection oriented design to allow each client to be handled
separately and unreachability to be detected more reliably.

configuration fails after group negotiation. This is because of a
regression from commit 1075b29571 that

Fix this by using an eloop timeout to free remove the P2P group so that

callers do not need to know about interface getting possibly removed. In
addition, move the P2P specific code into p2p_supplicant.c where it
really belongs. This allows the already existing group formation timeout
to be used by reducing the timeout to zero.

5bf9a6c859 P2P: Add event messages for possible PSK failures on P2P groups
It is possible for the GO of a persistent group to change the PSK or
remove a client when per-client PSKs are used and this can happen
without the SSID changing (i.e., the group is still valid, but just not
for a specific client). If the client side of such persistent group ends
up trying to use an invalidated persistent group information, the
connection will fail in 4-way handshake. A new WPS provisioning step is
needed to recover from this.

Detect this type of case based on two 4-way handshake failures when
acting as a P2P client in a persistent group. A new
"P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to
indicate when this happens. This makes it easier for upper layers to
remove the persistent group information with "REMOVE_NETWORK <persistent
group id>" if desired (e.g., based on user confirmation).

In addition to indicating the error cases for persistent groups, all
this type of PSK failures end up in the client removing the group with
the new reason=PSK_FAILURE information in the P2P-GROUP-REMOVED event.

SCARD: Non-USIM card - cannot do UMTS auth
EAP-AKA: UMTS authentication failed (AUTN)
wlan0: CTRL-EVENT-EAP-FAILURE EAP authentication failed
------------------

This occurs because on the first EAP-SIM authentication, the SIM/USIM
card in the device was recognized as SIM card even if it is USIM card.

So this patch changes it to recognize as USIM card even if EAP-SIM
authentication was required.

I have tested these switching cases.

86bd141050 Change WEP network selection to reject WPA/WPA2 APs

mimic a device that is not aware of WPA/WPA2 and as such, it tried to
connect to a WPA/WPA2 AP with the assumption that the AP could be
providing support for both WEP and WPA/WPA2 stations in the same BSS.
Such APs could have been used during transition from WEP to more secure
options, but that type of deployment have not been used in large number
and are not really of much use anymore taken into account that more or
less all new devices support WPA/WPA2. That combined with the preference
to deprecate WEP justifies removing this use case and making WEP
networking matching more strict by using the knowledge of AP advertising
WPA/WPA2 as an indication of WEP not being supported.

13adc57b39 IBSS RSN: Add peer restart detection
To better support the IBSS/RSN mechanism, wpa_supplicant has to be able
to detect a possible peer reboot and in this case it should start a new
EAPOL handshake.

To perform such reboot detection wpa_supplicant has to perform an Open
Authentication by sending an Authentication frame and then replying to
it. IF an Authentication frame is received when the key have already
been exchanged, wpa_supplicant understands that the peer has rebooted
and can reset its state machine.

Whenever a new peer is added to the IBSS wpa_supplicant will start the
Open Authentication and only after having accomplished it will start the
key exchange. If the driver does not support Authentication frame
exchange initiated from user space, this step is skipped to maintain
previous behavior (just go through EAPOL-Key frame processing).

The Open Authentication was partly supported by the Linux kernel but now
wpa_supplicant can register for Authentication frames, handle it in
userspace and so avoid any possible race condition.

conditional on !p2p_mgmt, but forced p2p_mgmt=1 for cases where the
driver does not use the dedicated P2P Device. Fix this by making the
!p2p_mgmt condition apply only if the driver does indicate use of a
dedicated P2P Device.

2e5ba4b6d1 P2P: Derive group interface name bit more sensibly
The interface name for the P2P group interface is derived from the
P2P management interface. When the P2P management interface is a
P2P Device interface, i.e., p2p-dev-wlanX, the name for the group
interface is abbreviated to p2p-X (X being group index). When the
P2P management interface starts with p2p-dev- use its postfix
instead. So P2P management interface p2p-dev-wlan3 results in group
interface name p2p-wlan3-0.

080585c01a Add support for OCSP stapling to validate server certificate
When using OpenSSL with TLS-based EAP methods, wpa_supplicant can now be
configured to use OCSP stapling (TLS certificate status request) with
ocsp=1 network block parameter. ocsp=2 can be used to require valid OCSP
response before connection is allowed to continue.

hostapd as EAP server can be configured to return cached OCSP response
using the new ocsp_stapling_response parameter and an external mechanism
for updating the response data (e.g., "openssl ocsp ..." command).

This allows wpa_supplicant to verify that the server certificate has not
been revoked as part of the EAP-TLS/PEAP/TTLS/FAST handshake before
actual data connection has been established (i.e., when a CRL could not
be fetched even if a distribution point were specified).

The use of AID=1 for the nl80211 dummy STA case is specific to the

55a2df4389 HS 2.0: Include HS 2.0 Indication element only for HS 2.0 association
The Hotspot 2.0 specification seems to mandate this element to be
included in all (Re)Association Request frames if the station is Hotspot
2.0 capable. However, that results in conflicts with other requirements
like no TKIP use when this element is present. The design is really
supposed to include the indication element only for Hotspot 2.0
associations regardless of what the current specification implies.
Remove the HS 2.0 Indication element from (Re)Association Request frame
whenever the connection is not for Hotspot 2.0 purposes.

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.

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

for drivers that use the connect API, so remove the limitation and allow

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

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.

for the GO to stop the group before this happens (i.e., send

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

3887878e53 TDLS: Remove link, if any, on an implicit set up request
If an implicit TDLS set up request is obtained on an existing link or an
to be established link, the previous link was not removed. This commit
disables the existing link on a new set up request. Also,
wpa_tdls_reneg() function was invoking wpa_tdls_start() on an already
existing peer for the case of internal setup, which is incorrect. Thus
the invocation of wpa_tdls_start() is removed in wpa_tdls_reneg() and
also this function is renamed to wps_tdls_remove() as it does not
renegotiation rather shall remove the link (if any) for the case of

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.

6fbcbc07e4 WPS: Optimize post-WPS scan even if EAP-Failure is not received
Commit 17a4734dc4 shall optimize the
post-WPS scan based on the channel used during the provisioning only
when the EAP-Failure frame is received. In cases where the EAP-Failure
frame is missed, this optimization shall not happen resulting in the
scan in all the channels thus consuming more time for the connection.
This commit enhances this by storing the requisite information after
the M8 frame is received.

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.

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 proto RSN
set_network 0 key_mgmt WPA-PSK
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.

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 \
    /fi/w1/wpa_supplicant1/Interfaces/0 \
    org.freedesktop.DBus.Properties.Get \

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.

b363121a20 WPS: Reject invalid credential more cleanly
If WPS Registrar tries to provision a WPA/WPA2-Personal network without
including a valid Network Key, the network block cannot be used to
connect to the network. Reject such credential without adding the
network block. This makes wpa_supplicant send WSC_NACK as a response to
the invalid Credential and stop the provisioning process immediately
rather than only after trying unsuccessfully to connect to the network.

96beff11d1 P2P: Allow discoverable interval for p2p_find to be configured
The new P2P_SET parameter disc_int can now be used to configure
discoverable interval for p2p_find operations. The format of the command
for setting the values is "P2P_SET disc_int <minDiscoverableInterval>
<maxDiscoverableInterval> <max TUs for discoverable interval>". The
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".

23270cd8f5 Restore wpa_s->scan_req if scan trigger fails
If the driver rejects the scan request while handling an external
requested scan (e.g., SCAN command on ctrl_iface), wpa_s->scan_req gets
cleared in wpa_supplicant_scan(). This can results in issues when the
scheduled re-try of the scan in one seconds trigger another call to this
function. If ap_scan==2 mode is used, this would result in new
association attempt instead of a new scan. Avoid this by restoring value
of wpa_s->scan_req in case the scan trigger fails and a new scan attempt
is scheduled.

5fbddfdcf1 P2P: Fix default p2p_group_idle timeout for P2P client role
Commit 0d30cc240f forced
wpa_s->current_ssid to be cleared in wpa_supplicant_mark_disassoc()
which gets called from wpa_supplicant_event_disassoc(). This breaks the
P2P group idle mechanism for the case where p2p_group_idle is not set
(i.e., is the default 0) since wpas_p2p_group_idle_timeout() ignores the
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.
