Jörg Krause acdf502197 WPS: Notify about WPS PBC event in Enrollee mode
Previously, the event "WPS-PBC-ACTIVE" was only generated when
wpa_supplicant is operating as WPS Registrar whereas "WPS-SUCCESS" or
"WPS-TIMEOUT" are generated for both, the Registrar and the Enrollee
roles.

Also generate the event when wpa_supplicant is operating as WPS Enrollee
to allow monitoring the begin and the end of a WPS PBC process.

Avraham Stern 13bf18eda5 WNM: Use a dynamically allocated buffer for BTM query and response
BSS transition management query and response use a large static buffer
for the frame because the candidate list may require a lot of space.
However, in most cases the actually used space will be much less than
the buffer (since the candidate list is short or completely missing).

Use a dynamically allocated buffer instead and allocate it according
to the actual space needed.

While at it, remove unneeded filling of the MAC header in the Action
frames, since this gets ignored and wpa_drv_send_action() adds the MAC
header anyway.

Jouni Malinen b696f791ac RRM: Fix wpas_rrm_send_msr_report() loop handling
The while (len) loop was updating the next pointer at the end even when
len == 0, i.e., when the new next value won't be used. This could result
in reading one octet beyond the end of the allocated response wpabuf.
While the read value is not really used in practice, this is not correct

Hu Wang 57d3c5913a Clear scan_res_handler on no-retry failure
Previously it was possible for wpa_s->scan_res_handler to remain set to
its old value in case wpa_drv_scan() failed and no retry for the scan
trigger was scheduled (i.e., when last_scan_req == MANUAL_SCAN_REQ).
This could result in getting stuck with the next connection attempt
after a failed "SCAN TYPE=ONLY" operation when wpa_s->scan_res_handler
was set to scan_only_handler().

Fix this by clearing wpa_s->scan_res_handler if wpa_drv_scan() fails and
no retry is scheduled.

difference was less than 5 dB. Since the throughput estimation take into
account SNR, this can be done in more cases. For now, add a conservative
2 dB more to the difference so that any SNR difference below 7 dB
results in BSS selection based on throughput estimates.

Add support to send GAS requests with a randomized transmitter address
if supported by the driver. The following control interface commands
(and matching configuration file parameters) can be used to configure
different types of randomization:

"SET gas_rand_mac_addr 0" to disable randomizing TX MAC address,
"SET gas_rand_mac_addr 1" to randomize the complete TX MAC address,
"SET gas_rand_mac_addr 2" to randomize the TX MAC address except for OUI.

A new random MAC address will be generated for every
gas_rand_addr_lifetime seconds and this can be configured with
"SET gas_rand_addr_lifetime <timeout>".

Günther Kelleter 41f140d386 Add hostapd options wpa_group_update_count and wpa_pairwise_update_count
wpa_group_update_count and wpa_pairwise_update_count can now be used to
set the GTK and PTK rekey retry limits (dot11RSNAConfigGroupUpdateCount
and dot11RSNAConfigPairwiseUpdateCount). Defaults set to current
hardcoded value (4).

Some stations may suffer from frequent deauthentications due to GTK
rekey failures: EAPOL 1/2 frame is not answered during the total timeout
period of currently ~3.5 seconds. For example, a Galaxy S6 with Android
6.0.1 appears to go into power save mode for up to 5 seconds. Increasing
wpa_group_update_count to 6 fixed this issue.

Sunil Dutt f47f936170 P2P: Override P2P_PEER group_capab with 0 if no matching BSS entry found
Relying on the group_capab from the P2P peer information can result in
improper information on whether the peer is currently operating as a GO.
However, there is a known implementation in Android that does this.

To reduce issues from this misuse in upper layer to try to determine
whether a specific peer is operationg a group, override the group_capab
value in P2P_PEER output with 0 if there are no BSS entries with the
peer P2P Device as a GO. This is not a perfect information since there
may not have been a recent scan on all channels, but this results in
less issues than trying to decide between new group formation and
joining an existing group based on stale or incorrect information.

Since no upper layer application is really supposed to use the
group_capab field value in P2P_PEER command, this change should not
cause any impact for properly design components and the possibility of
regressions is limited to cases that are already known to work
incorrectly in number of identifiable cases.

Jouni Malinen db5e53cb06 mesh: Fix struct hostapd_data initialization
The local custom version of allocating and initializing struct
hostapd_data within wpa_supplicant_mesh_init() is problematic. This has
already missed couple of initialization steps that are required. Instead
of trying to remember to keep this up to date, use
hostapd_alloc_bss_data() so that there is only one place for this
initialization.

This is fixing a recent issue where FILS HLP started using
hapd->dhcp_server and expected that to be initialized to -1. For the
mesh case, that did not happen and when removing the interface, the FILS
HLP implementation ended up unregistering eloop socket for
hapd->dhcp_server (= 0). This could result in missing socket callbacks
for an arbitrary socket.

Masashi Honma 4d77d80edd mesh: Add MESH_PMKSA_GET/ADD commands
These commnds are mesh version of PMKSA_GET/ADD commands. So the usage
and security risk is similar to them. Refer to
commit 3459381dd2 ('External persistent
storage for PMKSA cache entries') also.

The MESH_PMKSA_GET command requires peer MAC address or "any" as an
argument and outputs appropriate stored PMKSA cache. And the
MESH_PMKSA_ADD command receives an output of MESH_PMKSA_GET and re-store
the PMKSA cache into wpa_supplicant. By using re-stored PMKSA cache,
wpa_supplicant can skip commit message creation which can use
significant CPU resources.

The output of the MESH_PMKSA_GET command uses the following format:
<BSSID> <PMKID> <PMK> <expiration in seconds>

The example of MESH_PMKSA_ADD command is this.
MESH_PMKSA_ADD 02:00:00:00:03:00 231dc1c9fa2eed0354ea49e8ff2cc2dc cb0f6c9cab358a8146488566ca155421ab4f3ea4a6de2120050c149b797018fe 42930

Jouni Malinen b98706c14b RSN IBSS: Fix TK clearing on Authentication frame RX
When wpa_supplicant was processing a received Authentication frame (seq
1) from a peer STA for which there was already a TK configured to the
driver, debug log claimed that the PTK gets cleared, but the actual
call to clear the key was actually dropped due to AUTH vs. SUPP set_key
selection. Fix this by explicitly clearing the TK in case it was set
and an Authentication frame (seq 1) is received.

This fixes some cases where EAPOL-Key frames were sent encrypted using
the old key when a peer STA restarted itself and lost the key and had to
re-join the IBSS. Previously, that state required timing out the 4-way
handshake and Deauthentication frame exchange to recover.

Jouni Malinen 5cda350896 RRM: Move wpabuf_resize() call into wpas_rrm_report_elem()
wpabuf_resize() can handle the initial allocation of a wpabuf and all
the other callers of wpas_rrm_report_elem() were already using a pointer
to a pointer and a wpabuf_resize() call. Simplify this by resizing the
wpabuf (if needed) within wpas_rrm_report_elem() instead of having to
calculate the needed size in all the callers. Thsi is also fixing one of
the allocation sizes to use the correct size instead of a size of a
struct that has nothing to do with the allocation (but is larger than
the needed five octets, so does not break anything).

This could potentially result in get_ie() reading four octets beyond the

Jouni Malinen 3459381dd2 External persistent storage for PMKSA cache entries
This adds new wpa_supplicant control interface commands PMKSA_GET and
PMKSA_ADD that can be used to store PMKSA cache entries in an external
persistent storage when terminating a wpa_supplicant process and then
restore those entries when starting a new process. The previously added
PMKSA-CACHE-ADDED/REMOVED events can be used to help in synchronizing
the external storage with the memory-only volatile storage within
wpa_supplicant.

"PMKSA_GET <network_id>" fetches all stored PMKSA cache entries bound to
a specific network profile. The network_id of the current profile is
available with the STATUS command (id=<network_id). In addition, the
network_id is included in the PMKSA-CACHE-ADDED/REMOVED events. The
output of the PMKSA_GET command uses the following format:

<BSSID> <PMKID> <PMK> <reauth_time in seconds> <expiration in seconds>
<akmp> <opportunistic>

For example:

02:00:00:00:03:00 113b8b5dc8eda16594e8274df4caa3d4 355e98681d09e0b69d3a342f96998aa765d10c4459ac592459b5efc6b563eff6 30240 43200 1 0

The PMKSA_GET command uses the following format:

<network_id> <BSSID> <PMKID> <PMK> <reauth_time in seconds> <expiration
in seconds> <akmp> <opportunistic>

(i.e., "PMKSA_ADD <network_id> " prefix followed by a line of PMKSA_GET
output data; however, the reauth_time and expiration values need to be
updated by decrementing them by number of seconds between the PMKSA_GET
and PMKSA_ADD commands)

For example:

PMKSA_ADD 0 02:00:00:00:03:00 113b8b5dc8eda16594e8274df4caa3d4 355e98681d09e0b69d3a342f96998aa765d10c4459ac592459b5efc6b563eff6 30140 43100 1 0
PMKSA_ADD 0 02:00:00:00:04:00 bbdac8607aaaac28e16aacc9152ffe23 e3dd6adc390e685985e5f40e6fe72df846a0acadc59ba15c208d9cb41732a663 30140 43100 1 0

This functionality is disabled be default and can be enabled with
CONFIG_PMKSA_CACHE_EXTERNAL=y build configuration option. It should be
noted that this allows any process that has access to the wpa_supplicant
control interface to use PMKSA_ADD command to fetch keying material

would need to return more than P2P_MAX_PREF_CHANNELS (= 100) preferred

would need to return more than P2P_MAX_PREF_CHANNELS (= 100) preferred
channels for this to actually be able to read beyond the buffer. No
driver is known to return that many preferred channels, so this does not
seem to be reachable in practice.

Jouni Malinen 6e374bd44d Ignore scan results from ongoing scan when FLUSH command is issued
This makes wpa_supplicant behavior more consistent with FLUSH command to
clear all state. Previously, it was possible for an ongoing scan to be
aborted when the FLUSH command is issued and the scan results from that
aborted scan would still be processed and that would update the BSS
table which was supposed to cleared by the FLUSH command.

This could result in hwsim test case failures due to unexpected BSS
table entries being present after the FLUSH command.

Jouni Malinen cfadab269f nl80211: Move duplicate scan result removal to bss.c
The way the removal of duplicated (one per frequency) BSS entries in the
cfg80211 scan results were removed in driver_nl80211_scan.c
bss_info_handler() depended on having the full scan results available to
allow iteration through the other entries. This is problematic for the
goal of being able to optimize memory allocations for scan result
fetching in a manner that would not build the full result buffer in
memory.

Move this duplicate removal into bss.c since it has sufficient
information available for doing the same determination of which one of
two BSS entries is more current.

Sunil Dutt bf88401d23 Add support to abort vendor scan
This commit enhances the existing implementation of abort scan to also
abort concurrent active vendor scans. This is achieved by passing the
the scan_cookie to the driver interface with the intention to abort
the specific scan request. This scan_cookie is returned from the driver
interface when the scan request is scheduled.

This scan_cookie is 0 if the scan is triggered through the upstream
cfg80211 interface. Thus, the scan_cookie is used to determine whether
to abort the cfg80211 or vendor scan request.

Also, the previous implementation of relying on scan_work/p2p_scan_work
for the active work to trigger the abort scan is enhanced to check for
the started state of either of these work operations. This should also
help to abort the concurrent active scan/p2p-scan operations.

GHz band in cases where 2.4 GHz band has significantly higher signal
strength, but still a lower throughput estimate.

Make this less likely to happen by increasing/reducing the minimum

Sabrina Dubroca 6f551abdfc mka: Remove "channel" hacks from the stack and the macsec_qca driver
This is specific to the macsec_qca driver. The core implementation
shouldn't care about this, and only deal with the complete secure
channel, and pass this down to the driver.

Drivers that have such limitations should take care of these in their
->create functions and throw an error.

Since the core MKA no longer saves the channel number, the macsec_qca
driver must be able to recover it. Add a map (which is just an array
since it's quite short) to match SCIs to channel numbers, and lookup
functions that will be called in every place where functions would get
the channel from the core code. Getting an available channel should be
part of channel creation, instead of being a preparation step.

Jouni Malinen 4b5b8a53a1 WPS: Force BSSID for WPS provisioning step connection
This was already done for most driver cases, but it is possible that the
BSSID/frequency is not forced if the driver reports BSS selection
capability (e.g., NL80211_ATTR_ROAM_SUPPORT). That could potentially
result in the driver ignoring the BSSID/frequency hint and associating
with another (incorrect) AP for the WPS provisioning step if that
another AP in the same ESS is more preferred (e.g., better signal
strength) by the driver and only one of the APs (the not preferred one)
is in active WPS registrar state.

While most drivers follow the BSSID hint for the initial connection to
an ESS, not doing it here for the WPS provisioning would break the
protocol. Fix this by enforcing a single BSSID/frequency to disallow the
driver from selecting an incorrect AP for the WPS provisioning
association.

Avraham Stern 5ac8f8623d Fix PNO restart flow
PNO is sometimes restarted due to changes in scan parameters
(e.g., selected network changed or MAC randomization being
 enabled/disabled). Restart is done by stopping PNO and immediately
starting it again. This may result in the SCHED_SCAN_STOPPED event being
received after the request for new PNO, which will make wpa_supplicant
believe PNO is not active although it is actually is. As a result, the
next request to start PNO will fail because PNO is active and should be
stopped first.

Fix this by deferring the request to start PNO until the
SCHED_SCAN_STOPPED event is received in case sched_scan is being
stopped.

David Spinadel 1ac388633a Remove disconnected APs from BSS table if likely out-of-range
In some cases, after a sudden AP disappearing and reconnection to
another AP in the same ESS, if another scan occurs, wpa_supplicant might
try to roam to the old AP (if it was better ranked than the new one)
because it is still saved in BSS list and the blacklist entry was
cleared in previous reconnect. This attempt is going to fail if the AP
is not present anymore and it'll cause long disconnections.

Remove an AP that is probably out of range from the BSS list to avoid
such disconnections. In particular mac80211-based drivers use the
WLAN_REASON_DISASSOC_DUE_TO_INACTIVITY reason code in locally generated
disconnection events for cases where the AP does not reply anymore.

Jouni Malinen 5e993390f6 Initialize iface->sta_seen on allocation
Previously, struct hostapd_iface sta_seen list head was initialized only
when completing interface setup. This left a window for operation that
could potentially iterate through the list before the list head has been
initialized. While the existing code checked iface->num_sta_seen to
avoid this case, it is much cleaner to initialize the list when struct
hostapd_iface is allocated to avoid any accidental missing of the extra
checks before list iteration.

When starting a P2P GO, the struct p2p_go_neg_results may use
persistent_group == 2 to indicate use of persistent reconnect. Setting
ssid->p2p_persistent_group based on this did not take into account this
special case and that ended up in D-Bus code trying to encode 2 as a
DBUS_TYPE_BOOLEAN value which results in an assert from the library. Fix
this by setting ssid->p2p_persistent_group to 0 or 1 instead of raw
params->persistent_group value without any filtering.

This is similar to an earlier fix in commit
112fdee738 ('P2P: Fix D-Bus persistent
parameter in group started event') that addressed another code path in
sending out this D-Bus signal.

Nishant Chaprana 82b9ec3125 D-Bus: Add DeviceFoundProperties signal for discovered peers
This signal sends the peer properties to applications for discovered
peers. The signature of this event is "oa{sv}". This event is needed
because the current DeviceFound signal provides only the peer object
path. If there are many peers in range there will be many DeviceFound
signals and for each DeviceFound signal, applications would need to use
GetAll to fetch peer properties. Doing this many times would create
extra load over application as well as over wpa_supplicant, so it is
better to send peer properties in the event so that applications can
extract found peer information without extra steps.

The existing DeviceFound signal is left as-is to avoid changing its
signature.

The issue is not applicable to the control interface because the
P2P-DEVICE-FOUND event includes peer info in it, but over D-Bus
interface DeviceFound provides only the peer object.

Jouni Malinen c86bef2913 wpa_supplicant: Make GAS Address3 field selection behavior configurable
IEEE Std 802.11-2012, 10.19 (Public Action frame addressing) specifies
that the wildcard BSSID value is used in Public Action frames that are
transmitted to a STA that is not a member of the same BSS.
wpa_supplicant used to use the actual BSSID value for all such frames
regardless of whether the destination STA is a member of the BSS.

P2P does not follow this rule, so P2P Public Action frame construction
must not be changed. However, the cases using GAS/ANQP for non-P2P
purposes should follow the standard requirements.

Unfortunately, there are deployed AP implementations that do not reply
to a GAS request sent using the wildcard BSSID value. The previously
used behavior (Address3 = AP BSSID even when not associated) continues
to be the default, but the IEEE 802.11 standard compliant addressing
behavior can now be configured with gas_address3=1.

Lior David a26c9c2e71 Fix sending non-Public Action frames over P2P Device interface
The P2P Device interface can only send Public Action frames. Non-Public
Action frames must be sent over a group interface. The previous
implementation sometimes tried to send non-Public Action frames such as
GO Discoverability over the P2P Device interface, however, the source
address of the frame was set to the group interface address so the code
in offchannel.c knew to select the correct interface for the TX.

The check breaks when the P2P Device and group interfaces have the same
MAC address. In this case the frame will be sent over the P2P Device
interface and the send will fail.

Fix this problem in two places:
1. In offchannel, route non-Public Action frames to the GO
   interface when the above conditions are met.
2. When a TX_STATUS event arrives on such routed frame, it will
   arrive on the GO interface but it must be handled by the P2P Device
   interface since it has the relevant state logic.

Jouni Malinen 2a3f56502b Reject SET commands with newline characters in the string values
Many of the global configuration parameters are written as strings
without filtering and if there is an embedded newline character in the

This fixes an issue where wpa_supplicant could have updated the

accessible only for trusted users/applications, it may be possible that
an untrusted user has access to a management software component that
does not validate the value of a parameter before passing it to
wpa_supplicant.

This could allow such an untrusted user to inject almost arbitrary data
into the configuration file. Such configuration file could result in

1. Copy the NFC key data only if it was not set in the configuration

Hu Wang 3560b32ca3 Fix race condition with PNO stop followed immediately by PNO start
Commit dd271857a5 ('Skip normal scan when
PNO is already in progress') fixed issues with normal scans getting
rejected by the driver when PNO scan is already running. The part about
skipping such a scan request is fine, but the part about clearing
wpa_s->pno back to 0 in EVENT_SCHED_SCAN_STOPPED handler is problematic.

If PNO is stopped ("SET pno 0") and then restarted ("SET pno 1")
immediately, it is possible for the EVENT_SCHED_SCAN_STOPPED event from
the stopping part to be received only after the new PNO instance has
been started. This would have resulted in clearing wpa_s->pno and the
driver and wpa_supplicant getting out of sync. This would then prevent
PNO from being stopped with "SET pno 0" (that fails if wpa_s->pno == 0).

Fix this race condition by reverting the wpa_s->pno = 0 addition from
the EVENT_SCHED_SCAN_STOPPED handler.

Roshan Pius 7b4bbb9f94 binder: Add binder skeletal code for Android
Create the skeletal binder interface for wpa_supplicant. The interface
hierarchy is based off the existing dbus
interface(https://w1.fi/wpa_supplicant/devel/dbus.html).

Since we use libbinder, the binder interface codebase needs to be
written in C++ and can only be compiled on Android platform for now.

The aidl files define binder RPC interfaces. The Android build system
generates the corresponding C++ interface classes which needs to be
implemented by the server process.

The clients can obtain a reference to the binder service (root object)
using:
android::String16 service_name("fi.w1.wpa_supplicant");
android::sp<android::IBinder> binder =
  android::defaultServiceManager()->getService(service_name);

Once a reference to the root object is retrieved, the clients can
obtain references to other RPC objects using that root object methods.

Bala Krishna Bhamidipati 5cd317d381 Do not clear PMKSA entry or EAP session cache if config does not change
This avoids unnecessary flushing of the PMKSA cache entry and EAP
session data when processing SET_NETWORK commands that set a network
profile parameter to the same value that the parameter already has.

Introduce a new wpa_config_set() and wpa_config_set_quoted() return
value (==1) signifying that the new value being set for the
corresponding field equals to the already configured one so that the
caller can determine that nothing changed in the profile.

For now, this does not cover all the network profile parameters, but
number of the most commonly used parameters are included to cover the
Android use cases where the framework may have issued SET_NETWORK
commands that would have unnecessarily prevented use of PMKSA caching or
EAP fast reauthentication.

Masashi Honma 9f2cf23e2e mesh: Add support for PMKSA caching
This patch add functionality of mesh SAE PMKSA caching. If the local STA
already has peer's PMKSA entry in the cache, skip SAE authentication and
start AMPE with the cached value.

If the peer does not support PMKSA caching or does not have the local
STA's PMKSA entry in the cache, AMPE will fail and the PMKSA cache entry
of the peer will be removed. Then STA retries with ordinary SAE
authentication.

If the peer does not support PMKSA caching and the local STA uses
no_auto_peer=1, the local STA can not retry SAE authentication because
NEW_PEER_CANDIDATE event cannot start SAE authentication when
no_auto_peer=1. So this patch extends MESH_PEER_ADD command to use
duration(sec). Throughout the duration, the local STA can start SAE
authentication triggered by NEW_PEER_CANDIDATE even though
no_auto_peer=1.

This commit requires commit 70c93963ed
('SAE: Fix PMKID calculation for PMKSA cache'). Without that commit,
chosen PMK comparison will fail.

Lior David 94ad3c3389 P2P: Change order of P2P IE and frequencies set up
When setting up parameters for P2P scan, calculate the frequencies
for the scan before calculating the scan IE. This is because
the scan IE calculation may need information about the scan
frequencies in use.

Jouni Malinen bef5e9a862 Fix scan rescheduling from wpas_stop_pno to check postponed case
Commit 02e122a995 ('Reschedule scan from
wpas_stop_pno if it was postponed') uses wpa_s->scanning as the only
condition for automatically starting a postponed scan request from
EVENT_SCHED_SCAN_STOPPED event handler. However, wpa_s->scanning may be
set for sched_scan and as such, this can result in unexpected extra
scans without there having been any real postponed request.

Make this more accurate by verifying that there really is a pending
request for a scan before speeding up its start.

Lior David 96a26ab744 P2P: Support dedicated P2P_DEVICE without separate group interface
Add support for drivers with dedicated P2P_DEVICE interface, but without
group interface concurrency (only a single netdev is used). With such
devices, wpa_supplicant tried to use the p2p_dev interface instead of
the group interface and most P2P operations failed. Extend
wpa_supplicant to use the primary interface instead of a separate group
interface in such cases.

Lior David ba307f8528 P2P: Add a separate pointer to the P2P Device instance
In many places in the code there was a reference to wpa_s->parent to get
from group interface to p2p_dev interface. These places can break if
P2P_DEVICE interface would need to be used with the primary interface as
the group interface, since the parent of the primary interface points to
itself and not the p2p_dev interface.

Fix this by adding a separate "p2pdev" pointer to wpa_supplicant,
it will be the same as parent pointer in most cases but whenever
the primary interface is used as a group interface, change it to
point to the correct p2p_dev interface.
