While being associated, if an ANQP request is received for a different
AP that doesn't exist in the BSS list, the ANQP request will be sent on
the frequency of the AP that we are currently associated to.
In such a case, it is possible that the ANQP request would be sent on
a channel different than that of the requested AP, potentially delaying
other requests/activities.
Avoid sending the ANQP request to an AP that is not in the BSS list.

Commit 21efc940f6 ('wpa_supplicant: Do not

management interface from D-Bus. However, it did not take into account
the possibility of wpa_s->dbus_path and wpa_s->dbus_new_path being NULL
in such cases on number of code paths within the D-Bus handlers. This
could result in invalid arguments (NULL path) being provided to D-Bus
functions (mainly, dbus_message_iter_append_basic) and NULL pointer
dereference when iterating over all interfaces. Either of these could
make wpa_supplicant process terminate.
Fix this by explicitly checking that the interface-specific D-Bus path
has been registered before using it anywhere with D-Bus handlers. In
addition, find the correct wpa_s instance to fix P2P operations through
D-Bus when the P2P Device interface is used.

When iterating through WPS APs that do not advertise Selected Registrar
TRUE, limit the authentication timeout to 10 seconds instead of the full
70 second value used with IEEE 802.1X/EAP/WPS in general. This helps
speed up AP iteration for cases where a selected AP misbehaves and does
not reply to EAP exchanges. This should not really be needed, but there
seems to be deployed APs that do not implement WPS correctly and with
such APs in the radio range, this extra timeout can speed up the
iteration to allow the correct AP to be found before the WPS operation
times out.

Previously, wpa_supplicant was using number of scan iterations
(WPS_PIN_SCAN_IGNORE_SEL_REG = 3) to give some time for finding a WPS AP
with Selected Registrar TRUE before starting to iterate through all WPS
APs. While this works fine in most cases, some drivers may return the
initial three scan results so quickly that the total amount of time is
only couple of seconds in case none of the APs are initially advertising
Selected Registrar TRUE. To give some more time for APs (WPS Registrars)
to become ready, add an additional constraint on the iteration based on
time (WPS_PIN_TIME_IGNORE_SEL_REG = 5 seconds).

Previously, within-ESS roaming was skipped if the selected BSS did not

higher rates (HT/VHT MCS).

This modifies the BSS selection routines to calculate SNR and estimated
throughput for each scan result and then use the estimated throughput as

taking into account higher throughput rates if both the AP and local
device supports HT20, HT40, or VHT80. In addition, the maximum rate is
restricted based on SNR.
In practice, this gives significantly higher probability of selecting
HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not
low enough to prevent higher MCS use.

When an EVENT_SIGNAL_CHANGE occurs the bgscan is informed about this
change but the new RSSI value is not stored. In consequence, when
roaming candidates are evaluated, the RSSI value of the current BSS used
to compare is an old one obtained during the last scan rather than the
new one given by the signal change event. This leads sometimes to bad
decision when selecting a new BSS for roaming.

receiving a signal change event in order to have a very up-to-date

This can be used to provide more control to upper layers on network
blocks generated as part of Interworking network selection.
INTERWORKING_ADD_NETWORK behaves otherwise identically to
INTERWORKING_CONNECT, but it does not request a new connection after
having added the network block and it returns the network id of the
added network.
INTERWORKING_ADD_NETWORK followed by REASSOCIATE would behave more or
less identically to INTERWORKING_CONNECT, but this allows the created
network profile to be modified, if desired, and/or stored externally.
SELECT_NETWORK can also be used with the network id returned from
INTERWORKING_ADD_NETWORK to enforce that specific network profile to be
used for the next connection (though, it should be noted that this
behavior may not meet all Hotspot 2.0 requirements if there were other
enabled networks that could have higher priority).

Commit b31be3a0fd ('P2P: Add automatic GO
Negotiation vs. join-a-group selection') added this P2P_CONNECT 'auto'
parameter, but did not update any documentation on it.
Signed-off-by: Jouni Malinen <j@w1.fi>
If a separate P2P group interface was used, P2P_CONNECT-auto fallback to
GO Negotiation could result in use of freed memory and segmentation
fault. This happened in cases where the peer GO was found in some old
scans, but not in the first scan triggered by the P2P_CONNECT-auto
command ("P2P: Peer was found running GO in older scan -> try to join
the group" shows up in the debug log). In addition, the GO would still
need to reply to PD Request to allow this code path to be triggered.
When five scans for the GO were completed in this sequence, the P2P
group interface was removed as part of falling back to GO Negotiation.
However, that ended up dereferencing the freed wpa_s instance at the end
of scan event processing. Fix this by reordering code a bit and breaking
out from EVENT_SCAN_RESULTS processing if the interface could have been
removed.

When SAE authentication fails, wpa_supplicant retries four times. If all
the retries result in failure, SAE state machine enters BLOCKED state.
Once it enters this state, wpa_supplicant doesn't retry connection. This
commit allow connection retries even if the state machine entered
BLOCKED state.
There could be an opinion "Is this patch needed? User could know the SAE
state machine is in the BLOCKED mode by MESH-SAE-AUTH-BLOCKED event.
Then user can retry connection. By user action, SAE state machine can
change the state from BLOCKED to another.". Yes, this is a true at the

When noise floor measurements are not available, compute SNR
using default values for the noise floor. This helps steer us
towards 5 GHz BSSes in high signal strength environments.
In more detail...
Existing code prefers a 5 GHz BSS when the 5 GHz BSS's signal
strength is "close" to that of the 2.4 GHz BSS, or when both SNRs
are large. However, the mwifiex driver does not provide noise
floor measurements, so we can't compute SNRs.
Because mwifiex doesn't provide NF measurements, the "large SNR"
code wasn't effective. By using default values for the noise floor,
we can again compute SNRs, and decide that the SNR is high enough
that we shouldn't worry about the exact difference in SNR.
The default noise floor values (one for 2.4 GHz, and one for 5 GHz)
were chosen by measurement in a noisy environment, so they should be
conservative.
Note that while this patch is motivated by mwifiex, it affects
ath9k as well. Although ath9k provides noise floor measurements
in general, it will sometimes fail to provide a measurement for
one or more specific channels.
As a result of this patch, we'll always compare BSSes based on SNR
(either measured or estimated), rather than sometimes comparing
based on signal strength. ("Always" assumes that the
WPA_SCAN_LEVEL_DBM flag is set. It is for mwifiex and ath9k.)
While there:
- fix a whitespace issue (spaces -> tab)
- clean up existing comments
- update dump_scan_res to indicate whether the noise floor is
measured, or default

For wired IEEE 802.1X authentication, phase1="allow_canned_success=1"
can now be used to configure a mode that allows EAP-Success (and
EAP-Failure) without going through authentication step. Some switches
use such sequence when forcing the port to be authorized/unauthorized or
as a fallback option if the authentication server is unreachable. By
default, wpa_supplicant discards such frames to protect against
potential attacks by rogue devices, but this option can be used to
disable that protection for cases where the server/authenticator does
not need to be authenticated.
When enabled, this mode allows EAP-Success/EAP-Failure as an immediate
response to EAPOL-Start (or even without EAPOL-Start) and EAP-Success is
also allowed immediately after EAP-Identity exchange (fallback case for
authenticator not being able to connect to authentication server).

reasonable default behavior, but there may be cases where it is more

wait for user to do something.

retry behavior to be disabled. This will make wpa_supplicant abort

Linux kernel commit 576eb62598f10c8c7fd75703fe89010cdcfff596 ('bridge:
respect RFC2863 operational state') from 2012 introduced a regression
for using wpa_supplicant with EAPOL frames and a station interface in a
bridge. Since it does not look like this regression is going to get
fixed any time soon (it is already two years from that commit and over
1.5 from a discussion pointing out the regression), add a workaround in
wpa_supplicant to avoid this issue.
The wpa_supplicant workaround uses a secondary packet socket to capture
all frames (ETH_P_ALL) from the netdev that is in a bridge. This is
needed to avoid the kernel regression. However, this comes at the price
of more CPU load. Some of this is avoided with use of Linux socket
filter, but still, this is less efficient than a packet socket bound to
the specific EAPOL ethertype. The workaround gets disabled
automatically, if the main packet socket interface on the bridge
interface turns out to be working for RX (e.g., due to an old kernel
version being used or a new kernel version having a fix for the
regression). In addition, this workaround is only taken into use for the
special case of running wpa_supplicant with an interface in a bridge.

Currently, there is a race in open mesh networks where mesh STA A
receives a beacon from B and sends a peering open frame to initiate
peering. STA B, having not yet received a beacon from A and thus
created the corresponding station entry, will ignore all such open
frames. If the beacon interval is sufficiently long then peering
will not succeed as a result.
In fact B can simply create the station entry when the popen is
received, as is done in Linux's in-kernel MPM, avoiding the issue.

Previously, we would only free the station entry if a peering close
frame was received (freeing the station entry causes the kernel to
start sending peer candidate events again when suitable beacons are
received, triggering peering or authentication to restart).
The end result is the same in any case regardless of close reason:
if we leave holding state then peering has started again, so go
ahead and remove the station in all cases.

For Interworking connection to work, the SSID of the selected BSS needs

earlier scan with that AP has shown a hidden SSID configuration (e.g.,
when running hwsim test cases, but at least in theory, this could happen
with real use cases as well). When that happened, the incorrect BSS
entry may not have included RSN configuration and as such, it would get

not, try to find another BSS entry matching the same BSSID and use that,

Add WPA_DRIVER_FLAGS_HT_IBSS driver feature flag. Some drivers could not

When performing SAE authentication in mesh, one station may
initiate authentication by sending a COMMIT as soon as a peer
candidate is discovered. Previously we did this in mesh_rsn.c,
but this left some of the state initialization in a different
part of the code from the rest of the state machine, and we may
need to add other initializations here in the future, so move
that to a more central function.

It was possible for the interface not to be marked in INTERFACE_DISABLED
state in case the event was processed for P2P GO because the wpa_s
instance could have been removed in case of a separate group interface.
Change the state first to avoid leaving different state for the case
where separate group interface is not used.
Mark scan to be a normal scan on INTERFACE_ENABLED so that scanning
rules (e.g., skip scan if no networks enabled) get used consistently.

There is a race condition between receiving an AP stopped event and
netdev down event. These resulted in different group removal reasons on
a GO device (UNAVAILABLE for stop AP event coming first and REQUESTED
for netdev event first). Make this more consistent by reporting
UNAVAILABLE for both possible cases.

The new control interface command TEST_ALLOC_FAIL and GET_ALLOC_FAIL can
now be used to trigger memory allocation failures for testing purposes.
TEST_ALLOC_FAIL sets a failure conditions with
<count>:func[;func][;func]... string and GET_ALLOC_FAIL returns the
current state using the same format. Whenever an allocation is made with
a matching backtrace of calling functions, the count is decremented by
one and once zero is reached, the allocation is forced to fail.
Function names can be prefixed with either '=' or '?' to get different
matching behavior. '=' requires this specific function to be the next
one in the backtrace (i.e., do not skip any other functions in the list
which is the default behavior). '?' allows the function to be optionally
present in the backtrace.

entry->strarray_value was left to point to freed memory in case
os_realloc_array() failed. This resulted in the following
wpa_dbus_dict_entry_clear() trying to free an already freed memory area.
In addition, the separately allocated strings in the array would have
been leaked in such a case. Furthermore, wpa_dbus_dict_entry_clear() was
not prepared for the possibility of the initial os_calloc() call failing
and entry->strarray_value being NULL without array_len being cleared to
zero. That would have resulted in reading uninitialized memory and NULL
pointer dereference.

The error reply needs to be sent out as a response. The "out" label was
in incorrect place to allow that to happen; instead, it ended up leaking

The supplicant code does not try to control the actual channel of the
radio at any point. It simply passes the target peer and channel
parameters to the driver. It's the driver's responsibility to
periodically initiate TDLS channel-switch operations when TDLS
channel-switching is enabled.
Allow enable/disable operations to be invoked via the control interface.

Previously, role="enrollee" was required to be used to allow the AP mode
WPS operation to be started. This is incorrect since the AP/GO will
operate in Registrar role. Fix this by ignoring the role parameter when
AP (including P2P GO) mode is enabled.
Signed-off-by: Jouni Malinen <j@w1.fi>
Start of station-mode WPS PBC/PIN/Registrar/NFC operation would result
in the AP mode getting disabled. This can be particularly confusing for
the P2P GO case where the group would need to be stopped cleanly. As
such, it is better to reject these invalid operations rather than trying
to handle all corner cases needed to allow this to work robustly.
