37547ad63c wpa_supplicant: Increase authentication timeout if CAC is started
Timeout is increased by dfs_cac_ms from channel data, or by max CAC time
(10 minutes) if dfs_cac_ms is not defined. This is needed for some more
complex cases, e.g., when STA is acting as an active slave with DFS
offload enabled and decided to start CAC after receiving CONNECT
command, in such a case the 10 second timeout is too small and
wpa_supplicant need to wait for CAC completion or CAC timeout (up to 10
minutes).

Without such timeout modification wpa_supplicant will be unable to
connect to an AP on DFS channel, since the default authentication
timeout (10 s) is smaller than the minimum CAC time (60 s).

Tested with nl80211 DFS offload implementation.

The recently introduced sae_password parameter was only handled properly

Explicitly check the PMKSA cache entry to have matching SAE AKMP for the
case where determining whether to use PMKSA caching instead of new SAE
authentication. Previously, only the network context was checked, but a
single network configuration profile could be used with both WPA2-PSK

06b1a10434 SAE: Fix default PMK configuration for PMKSA caching case
The RSN supplicant state machine PMK was set based on WPA PSK even for
the cases where SAE would be used. If the AP allows PMKSA caching to be
used with SAE, but does not indicate the selected PMKID explicitly in
EAPOL-Key msg 1/4, this could result in trying to use the PSK instead of
SAE PMK. Fix this by not setting the WPA-PSK as default PMK for SAE
network profiles and instead, configuring the PMK explicitly from the
found PMKSA cache entry.

ee2c6bb5e5 Remove CONFIG_IEEE80211R_AP=y build option from wpa_supplicant
There is no existing mechanism for setting up AP mode functionality with
FT enabled, so there is not really much point in having a build option
for trying to include the AP-to-AP FT functionality into wpa_supplicant
either. Since this build option results in failures to complete the
build, simply remove it completely. This can be restored if there is
ever desire to enable FT functionality in wpa_supplicant controlled AP
mode.

d89edb6112 wpa_supplicant: Don't reply to EAPOL if pkt_type is PACKET_OTHERHOST
When wpa_supplicant is running on a Linux interface that is configured in
promiscuous mode, and it is not a member of a bridge, incoming EAPOL
packets are processed regardless of the Destination Address in the frame.
As a consequence, there are situations where wpa_supplicant replies to
EAPOL packets that are not destined for it.

This behavior seems undesired (see IEEE Std 802.1X-2010, 11.4.a), and can
be avoided by attaching a BPF filter that lets the kernel discard packets
having pkt_type equal to PACKET_OTHERHOST.

8fb2b35735 Clean up setting of iface->p2p_mgmt flag
Previously we set this flag to one in wpa_supplicant_init_iface() if
Wi-Fi controller does not have a dedicated P2P-interface.

This setting had effect only in scope of wpa_supplicant_init_iface() and
it contradicts with comment to struct wpa_interface::p2p_mgmt field.
This comment says that this flag is used only if Wi-Fi controller has
dedicated P2P-device interface.

Also it contradicts with usage of similiar p2p_mgmt field in struct
wpa_supplicant. Again struct wpa_supplicant::p2p_mgmt is set only for
dedicated P2P-device interface.

After this change wpa_interface become input argument to
wpa_supplicant_init_iface() that we are not modifying.

d53401c54b dbus: Redirect signal processing to the management device if present
This fixes sending of FindStopped, GroupFormationFailure, and
InvitationReceived signals in the case of separate P2P-Device interface.
This extends the coverage of the earlier commit
745d62322b ("dbus: Redirect P2P request to
the managment device if present") to these three functions that were
missing the redirection.

Some wireless controllers might have separate P2P-Device interface, see
as example result of 'iw dev':

phy#0
        Unnamed/non-netdev interface
                ...
                type P2P-device
                ...
        Interface wlp2s0
                type managed
                ...

In this case there is separate 'struct wpa_supplicant' created for this
p2p-dev-* device as result of 'wpa_supplicant_add_iface >
wpas_p2p_add_p2pdev_interface > wpa_supplicant_add_iface'.

This instance of wpa_supplicant is not registered in D-Bus
(wpas_dbus_register_*) since for corresponding P2P device interface flag
'struct wpa_interface > p2p_mgmt' is set.

But this instance is saved in p2p_init_wpa_s and is used for handling
P2P related D-Bus commands. Therefore we should look for D-Bus path in
the parent of p2p_init_wpa_s instance.

Without this change test dbus_p2p_discovery starts failing if we set
support_p2p_device in vm-run.sh.

45f7574d31 Propagate the EAP method error code
In the current implementation, upon an EAP method failure, followed by
an EAP failure, the EAP Status is propagated up in wpa_supplicant with a
general failure parameter string "failure". This parameter is used for a
notification on the dbus.

This commit reports the EAP method failure error code in a separate
callback.

The solution in this commit is generic to all EAP methods, and can be
used by any method that need to pass its error code. However, this
commit only implements the reporting for EAP-SIM and EAP-AKA methods
where the Notification Code (in AT_NOTIFICATION) is used as the method
specific error code value.

77a020a118 wpa_supplicant: Fix auth failure when the MAC is updated externally
When connecting to a WPA-EAP network and the MAC address is changed

 WPA: Send EAPOL(version=1 secure=0 mic=0 ack=1 install=0 pairwise=1 kde_len=22 keyidx=0 encr=0)

That's because wpa_supplicant computed the PMKID using the wrong (old)
MAC address used during the scan. wpa_supplicant updates own_addr when
the interface goes up, as the MAC can only change while the interface
is down. However, drivers don't report all interface state changes:
for example the nl80211 driver may ignore a down-up cycle if the down
message is processed later, when the interface is already up. In such
cases, wpa_supplicant (and in particular, the EAP state machine) would
continue to use the old MAC.

Add a new driver event that notifies of MAC address changes while the
interface is active.

a0bf1b68c0 Remove all PeerKey functionality
This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.

This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.

Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

f516090228 P2P: Prefer 5/60 GHz band over 2.4 GHz during GO configuration
Previously, wpas_p2p_select_go_freq_no_pref() ended up selecting a 2.4
GHz band channel first before even considering 5 or 60 GHz channels.
This was likely done more or less by accident rather than by design when
the 5 GHz and 60 GHz band extensions were added. It seems reasonable to
enhance this by reordering the code to start with 5 and 60 GHz operating
classes and move to 2.4 GHz band only if no channel was available in 5
or 60 GHz bands for P2P GO use.

This does have some potential interop issues with 2.4 GHz only peer
devices when starting up an autonomous GO (i.e., without there being
prior knowledge of channels that the peers support). Upper layers are
expected to enforce 2.4 GHz selection if that is needed for some use
cases.

2efc672075 Fix RSN pre-authentication regression with pre-connection scan results
The introduction of radio works and a delayed callback to complete
association/connection requests ended up breaking RSN pre-authentication
candidate list generation for the case of pre-connection scan results.
Previously, wpa_supplicant_associate() set the RSN state machine
configuration before returning and the calls to
wpa_supplicant_rsn_preauth_scan_results() immediately after this
function call were working fine. However, with the radio work callback,
the RSN state machine configuration started to happen only in that
callback which would be called soon after this code path has completed.
This resulted in the RSN state machine not knowing the selected SSID and
as such, rejecting all pre-authentication candidates.

Fix this by setting the RSN state machine configuration from
wpa_supplicant_associate() so that the existing callers of
wpa_supplicant_rsn_preauth_scan_results() can be used as-is to add
candidates for pre-authentication.

for calling wpa_supplicant_event_assoc_auth() from EVENT_ASSOC handling
in case of FILS-completion with driver-based-SME. However, that checked
what placed outside the data != NULL case while data != NULL needs to
apply for this case as well due to wpa_supplicant_event_assoc_auth()
behavior. Move the data != NULL check to apply to both cases to avoid
potentially issues if a driver interface were to return EVENT_ASSOC
without the associate data. (CID 164708)

d4d76d9835 Fix offchannel TX done handling for sequence of TX frames
There could be multiple pending TX operations and if the earlier ones
have used wait_time, but the last one did not, the driver call for
canceling pending wait was not done. This could result in the driver
getting stuck waiting for the previously scheduled wait time and not
being able to do new operations until that. Fix this by canceling the
wait if any of the past offchannel_send_action() calls since the last
offchannel_send_action_done() used non-zero wait_time.

This was showing up as issues in certain DPP Public Action frame
sequences when the same offchannel operation is used with multiple
frames and the last frame in the sequence does not need wait_time.

618aa22900 P2P: Fix p2p_in_provisioning clearing in failure case
wpa_s->p2p_in_provisioning needs to be cleared when group formation
fully completes. The change to postpone GO side handling to the first
data connection in commit 41f853235f
('P2P: Extend group formation timeout on GO to first data connection')
resulted in making this not happen in one P2P Client side case: EAP-WSC
timeout in PBC case. While that is quite special case since it requires
30 second timeout without receiving new EAPOL frames and not getting
disassociation, it can apparently happen in some cases in practice. This
would result in new P2P operations (e.g., P2P_FIND) getting rejected
until wpa_supplicant is restarted.

Fix this by clearing wpa_s->p2p_in_provisioning whenever processing a
group formation failure case. For group formation success,
wpa_s->p2p_in_provisioning is left set to non-zero value to avoid
breaking the earlier limits on the GO side.

3c2bd55f03 P2P: wpas_p2p_select_go_freq() to check for supported pref_freq
This commit is similar to the commit
783c2920cc ('P2P: Check if the pref_freq
reported by the driver supports P2P') but extends the check for
supported pref_freq to wpas_p2p_select_go_freq().

This avoids issues with P2P_GROUP_ADD ending up selecting an unexpected
channel when get_pref_freq_list() (i.e.,
QCA_NL80211_VENDOR_SUBCMD_GET_PREFERRED_FREQ_LIST) is used. Filter the
list by removing channels that do not allow P2P operation at all.
Previously, only the explicitly disallowed channels were removed and
that could have resulted in selecting an operating channel that is not
allowed for P2P and failing to complete the operation to start the
group.

3d5f0e916d wpa_supplicant: Avoid associating to temp disabled SSID in ap_scan=2
In ap_scan=2 mode, wpa_supplicant_assoc_try() did not check whether the
SSID is temporarily disabled before trying to associate and this may
result in an infinite connect/disconnect loop. If the association
succeeds while the SSID is temporarily disabled, wpa_supplicant will
request to deauthenticate and that in turn will cause the SSID to be
temporarily disabled again. Fix that by postponing the association until
the SSID is no longer temporarily disabled.

b4d56efb1a Use throughput estimate-based BSS selection with larger SNR difference
Previously, the est_throughput comparison was done only when SNR
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.

In addition, the throughput estimates require SNR values to be
available, so separate this from the 5 GHz preference that can be done
based on either SNR or qual values.

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.

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.

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>

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.

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

incremented the request pointer by four within
wpas_rrm_build_lci_report() without decrementing len correspondingly.
This could potentially result in get_ie() reading four octets beyond the
buffer if a corrupted request is received. This would be applicable only
if the LCI reporting was enabled explicitly ("SET LCI ..." control
interface command).

Fix this by updating the len variable to match the request pointer

274e76f22f mesh: Fix channel configuration in pri/sec switch case
If 20/40 MHz co-ex scan resulted in switching primary and secondary
channels, mesh setup failed to update the frequency parameters for
hostapd side configuration and that could result in invalid secondary
channel configuration preventing creating of the mesh network. This
could happen, e.g., when trying to set up mesh on 5 GHz channel 36 and
co-ex scan finding a BSS on channel 40. Switching the pri/sec channels
resulted in hostapd code trying to check whether channel 32 is
available. Fix this by swapping the channels for hostapd configuration
when needed.

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
(PMK), so this is for environments in which the control interface access
is restricted.

Commit 8e84921efe ('P2P: Support driver
preferred freq list for Autonomous GO case') introduced this loop to go
through preferred channel list from the driver. The loop does bounds
checking of the index only after having read a value from the array.
That could in theory read one entry beyond the end of the stack buffer.

Fix this by moving the index variable check to be done before using it
to fetch a value from the array.

This code is used only if wpa_supplicant is build with
CONFIG_DRIVER_NL80211_QCA=y and if the driver supports the vendor
extension (get_pref_freq_list() driver op). In addition, the driver
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.

The way the removal of duplicated (one per frequency) BSS entries in the

bss_info_handler() depended on having the full scan results available to

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.

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.

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.

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.

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.

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.

3b208346ec ctrl_iface: BSS command to skip info items if parsing fails
In some cases parsing of the mesh scan info for a BSS or the P2P scan
info can fail. One reason can be that the Beacon/Probe Response frame
contained malformed length vendor IEs which are not parsed when adding
to the BSS table. Instead of skipping the whole BSS of the BSS command,
just skip the part that failed to parse.

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.

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.

73e4abb24a Reject psk parameter set with invalid passphrase character
WPA/WPA2-Personal passphrase is not allowed to include control
characters. Reject a passphrase configuration attempt if that passphrase
includes an invalid passphrase.

This fixes an issue where wpa_supplicant could have updated the
configuration file psk parameter with arbitrary data from the control
interface or D-Bus interface. While those interfaces are supposed to be
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 passphrase value before passing it to
wpa_supplicant.

This could allow such an untrusted user to inject up to 63 characters of
almost arbitrary data into the configuration file. Such configuration
file could result in wpa_supplicant trying to load a library (e.g.,
opensc_engine_path, pkcs11_engine_path, pkcs11_module_path,
load_dynamic_eap) from user controlled location when starting again.
This would allow code from that library to be executed under the
wpa_supplicant process privileges.

9b377be037 P2P: Copy config from p2pdev when not using dedicated group interface
When the P2P Device interface is used and an existing interface is used
for P2P GO/Client, the P2P Device configuration was not cloned to the
configuration of the existing interface. Thus, configuration parameters
such as idle_group_time, etc., were not propagated to the P2P GO/Client
interface.

Handle this by copying all configuration parameters of the P2P device
interface to the reused interface, with the following exceptions:

1. Copy the NFC key data only if it was not set in the configuration
   file.
2. The WPS string fields are set only if they were not previously set
   in the configuration of the destination interface (based on the
   assumption that these fields should be identical among all
   interfaces).

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.

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.

This avoids unnecessary flushing of the PMKSA cache entry and EAP

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

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

c3dc68e844 Do not invalidate EAP session cache on all network block parameter changes
The bssid and priority parameters in a network block do not have any
effect on the validity of an EAP session entry, so avoid flushing the
cached session when only these parameters are changed. This is mainly to
allow forced roaming or network selection changes without causing fast
reauthentication to be disabled if the changes are done during RSN
association that used EAP.

c6c29be1bd Interworking: Add credential realm to EAP-TLS identity
If the configured credential includes a username without '@' (i.e., no
realm) in it and a realm, combine these to form the EAP-Request/Identity
value as "<username>@<realm>" for EAP-TLS. This was already done for
EAP-TTLS as part of the anonymous NAI conversion, but EAP-TLS could have
ended up using a username without any realm information which would be
unlikely to work properly with roaming cases.

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

b907491281 wpa_supplicant: Basic support for PBSS/PCP
PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for IEEE 802.11ad devices.

Add a new "pbss" argument to network block. The argument is used
in the following scenarios:
1. When network has mode=2 (AP), when pbss flag is set will start
as a PCP instead of an AP.
2. When network has mode=0 (station), when pbss flag is set will
connect to PCP instead of AP.

The function wpa_scan_res_match() was modified to match BSS according to
the pbss flag in the network block (wpa_ssid structure). When pbss flag
is set it will match only PCPs, and when it is clear it will match only
APs.

NOTE: kqueue has to be closed and re-build after forking. epoll *should*
do the same, but it seems that wpa_supplicant doesn't need it at least.

I have re-worked a little bit of the epoll code (moved into a similar
kqueue function) so it's trivial to requeue epoll if needed in the
future.

df9e2c2a55 D-Bus: Don't do <deny send_interface="..." /> in dbus service file
It does more than intended; apart from denying messages to that
particular interface it also denies all messages non-qualified with an
interface globally. This blocks messages completely unrelated to
wpa_supplicant, such as NetworkManager communication with the VPN
plugins.

From the dbus-daemon manual:

  Be careful with send_interface/receive_interface, because the
  interface field in messages is optional. In particular, do NOT
  specify <deny send_interface="org.foo.Bar"/>! This will cause
  no-interface messages to be blocked for all services, which is almost
  certainly not what you intended. Always use rules of the form: <deny
  send_interface="org.foo.Bar" send_destination="org.foo.Service"/>

We can just safely remove those rules, since we're sufficiently
protected by the send_destination matches and method calls are
disallowed by default anyway.

9684c7567e mesh: Fix peer link counting when a mesh peer reconnects
When a mesh point reconnects by starting from Authentication frame
sequence, the plink count was not decremented from its last connection.
This resulted in leaking peer link count and causing wpa_supplicant to
reject the connection after max_peer_links (default: 99) reconnects.

This was reproduced by pre-configuring 2 mesh points with mesh
credentials. Boot both mesh points and make sure they connect to each
other. Then in a loop reboot one of the mesh points after it
successfully connects while leaving the other mesh point up and running.
After 99 iterations the supplicant on mesh point that is not rebooting
will reject the connection request from the other mesh point.

Fix this by decrementing num_plinks when freeing a STA entry that is
still in PLINK_ESTAB state.

83fe38b011 P2P: Fall back to no VHT when starting AP/P2P GO
In cases where the bandwidth is not set when starting an AP/P2P GO,
the code tries to use 160 MHz or 80 MHz channels. As a result, the
AP/P2P GO configuration is set to use these channel widths even if
they are not available, which may results in failing to start the
AP/P2P GO.

Fix this by changing the AP/P2P GO configuration not to use VHT channels
when they are not available. In this case the AP/P2P GO will use a 40
MHz channel, if available, or a 20 MHz channel, if this is the maximum
available width.

8fb718a748 GAS: Shorten the duration of the wait for GAS comeback response
When exchanging GAS frames with the AP, the initial response from the AP
may take a while to come, since the AP may need to fetch the info from a
server. The next fragments/comeback response frames should take much
less time since the AP already has all of the info, so the wait time
for these frames can be reduced.

In addition, some drivers, e.g., mac80211, try to combine ROC based flows,
to improve medium utilization. For example, if the requested ROC fits
entirely in a previous requested ROC they can be combined. Thus, reducing
the wait time for the next frames can improve medium utilization.

Shorten the duration of GAS comeback to improve medium utilization and
overall GAS exchange times.

8dd5c1b4e9 HS 2.0: Add a command to retrieve icon with in-memory storage
This adds a new command based Hotspot 2.0 icon retrieval option.

In short, here is the new command sequence:
1. REQ_HS20_ICON <bssid> <file-name>
2. event: RX-HS20-ICON <bssid> <file-name> <size>
3. GET_HS20_ICON <bssid> <file-name> <offset> <size>
   (if needed, repeat with larger offset values until full icon is
   fetched)
5. DEL_HS20_ICON <bssid> <file-name>

REQ_HS20_ICON is a new command that is analogous to HS20_ICON_REQUEST
with the slight difference that an entry to store the icon in memory is
prepared. The RX-HS20-ICON event has been augmented with BSSID,
file-name and size, and GET_HS20_ICON is used to retrieve a chunk of up
to <size> bytes of icon data at offset <offset>. Each chunk is returned
as a base64 encoded fragment, preceded by "HS20-ICON-DATA", BSSID, and
file-name as well as the starting offset of the data.

If there is no entry prepared for the icon when the ANQP result comes
back, hs20_process_icon_binary_file falls back to legacy behavior.

Finally the DEL_HS20_ICON command deletes (all) icons associated with
BSSID and file-name (there could be several if retries are used and they
have different dialog tokens).

disable monitoring. The hysteresis value is RSSI hysteresis in dB to
specify the minimum amount of change before a consecutive event is
reported.

With nl80211 driver interface, these values map to the
NL80211_CMD_SET_CQM command with NL80211_ATTR_CQM_RSSI_THOLD and
NL80211_ATTR_CQM_RSSI_HYST attributes to the driver.

This command cannot be used when bgscan module is in use since that
depends on being able to control the connection monitoring parameters.

2c0d0ae370 GAS: End remain-on-channel due to delayed GAS comeback request
During the sequence of exchanging GAS frames with the AP, the AP can
request to come back in X amount of time and resend the GAS request.

Previously, wpa_supplicant did not terminate the remain-on-channel
session, but rather waited until the requested comeback delay had
expired, and then tried to send the GAS frame (potentially to save the
time that is required to schedule a new remain on channel flow).

This might cause unnecessary idle time (can be close to 1000 ms) in
which the device might be off-channel. Ending the current
remain-on-channel session and then rescheduling makes better usage of
the time in this case.

End remain-on-channel session due to receiving a delayed GAS comeback
request from the AP.

685ea2f60c wpa_cli: Send ALL_STA command to the correct interface
wpa_ctrl_command_sta(), called by the "ALL_STA" handler, didn't consider
ifname_prefix, resulting in various commands being sent to the global
control interface, rather than the specified interface when IFNAME=
prefix was used.

This in turn caused the unexpected "UNKNOWN COMMAND" result be
considered as valid station, resulting in infinite loop while trying to
get all stations.

Fix it by considering ifname_prefix, similarly to _wpa_ctrl_command().

3c108b7573 EAP peer: External server certificate chain validation
This adds support for optional functionality to validate server
certificate chain in TLS-based EAP methods in an external program.
wpa_supplicant control interface is used to indicate when such
validation is needed and what the result of the external validation is.

This external validation can extend or replace the internal validation.
When ca_cert or ca_path parameter is set, the internal validation is
used. If these parameters are omitted, only the external validation is
used. It needs to be understood that leaving those parameters out will
disable most of the validation steps done with the TLS library and that
configuration is not really recommend.

By default, the external validation is not used. It can be enabled by
addingtls_ext_cert_check=1 into the network profile phase1 parameter.
When enabled, external validation is required through the CTRL-REQ/RSP
mechanism similarly to other EAP authentication parameters through the
control interface.

The request to perform external validation is indicated by the following
event:
CTRL-REQ-EXT_CERT_CHECK-<id>:External server certificate validation needed for SSID <ssid>

Before that event, the server certificate chain is provided with the
CTRL-EVENT-EAP-PEER-CERT events that include the cert=<hexdump>
parameter. depth=# indicates which certificate is in question (0 for the
server certificate, 1 for its issues, and so on).

The result of the external validation is provided with the following
command:
CTRL-RSP-EXT_CERT_CHECK-<id>:<good|bad>

It should be noted that this is currently enabled only for OpenSSL (and
BoringSSL/LibreSSL). Due to the constraints in the library API, the
validation result from external processing cannot be reported cleanly
with TLS alert. In other words, if the external validation reject the
server certificate chain, the pending TLS handshake is terminated
without sending more messages to the server.

63502c64e1 P2P: Fix P2P_CANCEL for p2p_in_invitation case
Commit f05cee9714 ('P2P: Clear
p2p_in_invitation on cancel') added a wpas_p2p_cancel() case to call
wpas_p2p_group_formation_failed() if wpa_s->p2p_in_invitation is set.
This is done in a loop going through wpa_s->next pointers. However, the
call here can result in removing the interface and freeing wpa_s. The
following attempt to read wpa_s->next is from freed memory and that can
result in process termination when using a separate P2P group interface
and issuing P2P_CANCEL on a group that was started through re-invocation
of a persistent group.

The recent commit 328f49acfe ('P2P:
Complete group formation on client data connection') "fixed" this by
accident since wpa_s->p2p_in_invitation gets cleared in the sequence
that could hit this issue and this results in P2P_CANCEL getting
rejected. However, the real bug here is in the loop that continues after
possible wpa_s instance deletion. Fix that by breaking out of the loop.

wpa_s->global->p2p_group_formation. However, in the P2P Client role,
that was done already at the completion of the WPS exchange. This can be
problematic since group formation timeout may still try to clear the

group interface may not be found.

it will be done by wpa_supplicant on wpa_drv_init() when setting

In addition, it may cause wpa_supplicant to fail initializing the

optional, and use it only when the interface is added by hostapd but not

the wpa_supplicant re-enable-networks-after-WPS 10 second timeout to

73ed03f333 wpa_supplicant: Add GTK RSC relaxation workaround
Some APs may send RSC octets in EAPOL-Key message 3 of 4-Way Handshake
or in EAPOL-Key message 1 of Group Key Handshake in the opposite byte
order (or by some other corrupted way). Thus, after a successful
EAPOL-Key exchange the TSC values of received multicast packets, such as
DHCP, don't match the RSC one and as a result these packets are dropped
on replay attack TSC verification. An example of such AP is Sapido
RB-1732.

Work around this by setting RSC octets to 0 on GTK installation if the
AP RSC value is identified as a potentially having the byte order issue.
This may open a short window during which older (but valid)
group-addressed frames could be replayed. However, the local receive
counter will be updated on the first received group-addressed frame and
the workaround is enabled only if the common invalid cases are detected,
so this workaround is acceptable as not decreasing security
significantly. The wpa_rsc_relaxation global configuration property
allows the GTK RSC workaround to be disabled if it's not needed.

67deaa582d l2_packet: Add build option to disable Linux packet socket workaround
Linux packet socket workaround(*) has an impact in performance when the
workaround socket needs to be kept open to receive EAPOL frames. While
this is normally avoided with a kernel that has the issue addressed by
closing the workaround packet socket when detecting a frame through the
main socket, it is possible for that mechanism to not be sufficient,
e.g., when an open network connection (no EAPOL frames) is used.

Add a build option (CONFIG_NO_LINUX_PACKET_SOCKET_WAR=y) to disable the
workaround. This build option is disabled by default and can be enabled
explicitly on distributions which have an older kernel or a fix for the
kernel regression.

Also remove the unused variable num_rx.

(*) Linux kernel commit 576eb62598f10c8c7fd75703fe89010cdcfff596
('bridge: respect RFC2863 operational state') from 2012 introduced a
regression for using wpa_supplicant with EAPOL frames and a station

cd571e14dd P2PS: Fix persistent group reporting in wpas_p2ps_prov_complete()
When one peer doesn't include a persistent group info in PD Request
the other peer shouldn't report a persistent group usage with this
peer even if such a persistent group exists locally. This condition
could be violated in the previous implementation.

In case a local persistent group exists and the
wpas_p2ps_prov_complete() function is called with persist_ssid parameter
set to NULL, wpa_supplicant reported P2PS-PROV-DONE with persist=<idx>
instead of conncap=<role> parameter.

This happened because the wpas_p2p_get_persistent() function was called
without verification whether the persist_ssid was set to NULL. In this
case the wpas_p2p_get_persistent() returns the first existing persistent
group matching the P2P Device Address without verifying the group's
SSID. After that the group ID is used as persist=<idx> parameter of
P2PS-PROV-DONE event.

Fix the issue by adding persist_ssid and persist_ssid_size verification
as a condition for the wpas_p2p_get_persistent() call.

23dcb302eb P2P: Relax wpas_p2p_init_go_params() for P2P GO CSA
wpas_p2p_move_go_csa() uses wpas_p2p_init_p2p_params() to select the
frequency to move to. However, it is possible that all the channels are
already used, so the selection of a new frequency would fail, although
the frequency used by the P2P GO should not be considered as used if it
is the only one using it.

To overcome this, allow the frequency selection to continue even if all
the frequencies are in use, but the frequency used by the P2P GO is not
used by any station interface.

Allow wpa_supplicant to use vendor scan (if supported by the driver)
together with the normal nl80211 scan and handling external scan events.
Since this results in possibility of concurrent scan operations, some of
the operations related to scan results need to check more carefully when

c9cfa6a9af Android: Avoid same per-iface and global ctrl socket
Android platform assigns the same socket id if the socket identifier in
conf->ctrl_interface and global->params.ctrl_interface (parameter for
android_get_control_socket) point to the same Android specific control
socket. This ends up having two eloop socket handlers registered for the
same file descriptor and thus, two attempt to receive and process each
command. This can result in unexpected failure, e.g., the prefix IFNAME=
for any command is valid for global socket handler, but results in
UNKNOWN COMMAND response from the per-interface ctrl socket handler).

Since it might be possible to end up with this type of invalid
configuration in OTA upgrade, compare the socket identifiers and do not
open the ctrl socket on the respective interface if both point to same.
This allows the Wi-Fi framework to use the global control interface.

5a1d9d1a8e Avoid reconnection on ENABLE_NETWORK if already connected
This was already the case for most command sequences, but it was
possible for wpa_s->reassociate to be set to 1 when CTRL-RSP-* commands
were used to set identity, password, or passphrase for EAP
authentication. In such cases, ENABLE_NETWORK issued after the
connection was completed could result in a new connection attempt
(likely reconnection back to the same BSS).

Fix this by checking whether an actual connection is already present
even if wpa_s->reassociate is set when processing the ENABLE_NETWORK
command.

ce7d0eb184 Update AP WPA/RSN IE on all associations if driver can select BSS
It is possible for driver-based BSS selection to end up reassociating
back to the current AP. If wpa_supplicant preferred another BSS, it
would have updated the internal knowledge of the AP's WPA/RSN IE when
requesting a new connection. In the special case of existing association
and new association being with the same BSS that is different from the
wpa_supplicant preference, association event processing skipped the
WPA/RSN IE update. This could result in the following 4-way handshake
getting rejected due to incorrectly detected mismatch with AP's RSN/WPA
IE between Beacon/Probe Response frame and EAPOL-Key msg 3/4.

Fix this by updating the AP WPA/RSN IE on all association events when
driver-based BSS selection is used regardless of whether the BSSID
changes. This could also cover a theoretical case of the AP changing its
RSN/WPA IE at the very moment we try to reassociate back to the same
BSS.
