b2ad4e6b24 D-Bus: Fix P2P NULL dereference after interface removal
When the P2P management interface is deleted, P2P is then disabled and
global->p2p_init_wpa_s is set to NULL. After that, other interfaces can
still trigger P2P functions (like wpas_p2p_find()) using D-Bus. This
makes wpa_supplicant terminate with SIGSEGV, because it dereferences a
NULL pointer. Fix this by adding proper checks, like it's done with
wpa_cli.

1b5865a53f SAE: Ignore commit message when waiting for confirm in STA mode
Previously, an unexpected SAE commit message resulted in forcing
disconnection. While that allowed recovery by starting from scratch,
this is not really necessary. Ignore such unexpected SAE commit message
instead and allow SAE confirm message to be processed after this. This
is somewhat more robust way of handling the cases where SAE commit
message might be retransmitted either in STA->AP or AP->STA direction.

50a2c8c906 Do not indicate possible PSK failure when using SAE
wpa_key_mgmt_wpa_psk() includes SAE AKMs. However, with SAE, there is no
way of reaching 4-way handshake without the password having already been
verified as part of SAE authentication. As such, a failure to complete
4-way handshake with SAE cannot indicate that the used password was
incorrect.

a82aee1f40 wpa_supplicant: Add support for EDMG channels
As part of a connection request, set EDMG parameters for the driver to
use in the association. The EDMG parameters are based on EDMG IE
received from the AP's Probe Response frames, the driver's EDMG
capability, and the EDMG configuration from the configuration.

As part of starting an AP, set EDMG parameters for the driver to use for
AP operation. The EDMG parameters are based on the driver's EDMG
capability and the EDMG configuration from the configuration.

This implementation is limited to CB2 (channel bonding of 2 channels)
and the bonded channels must be adjacent, i.e., the supported values for
edmg_channel are 9..13.

c349174035 MBO/OCE: Update disable_mbo_oce flag after association
After roaming to an AP, update disable_mbo_oce flag based on the current
BSS capabilities. This flag is used to check whether STA should support
MBO/OCE features and process BTM request received from the current
connected AP.

When a STA roams from a WPA2 MBO/OCE AP with PMF enabled to a
misbehaving WPA2 MBO/OCE AP without PMF, or if the driver chooses a BSS
in which PMF is not enabled for the initial connection, BTM requests
from such APs should not be processed by STA.

2e06cef80a MBO/OCE: Work around misbehaving MBO/OCE APs that use RSN without PMF
The MBO and OCE specification require the station to mandate use of PMF
when connecting to an MBO/OCE AP that uses WPA2. The earlier
implementation prevented such misbehaving APs from being selected for
connection completely. This looks like the safest approach to take, but
unfortunately, there are deployed APs that are not compliant with the
MBO/OCE requirements and this strict interpretation of the station
requirements results in interoperability issues by preventing the
association completely.

Relax the approach by allowing noncompliant MBO/OCE APs to be selected
for RSN connection without PMF to avoid the main impact of this
interoperability issue. However, disable MBO/OCE functionality when PMF
cannot be negotiated to try to be as compliant as practical with the
MBO/OCE tech spec requirements (i.e., stop being an MBO/OCE STA for the
duration of such workaround association). Also disable support for BTM
in this workaround state since MBO would expect all BTM frames to be
protected.

b10e01a795 DPP2: Connection status result (Configurator)
A new argument to the DPP_AUTH_INIT command (conn_status=1) can now be
used to set Configurator to request a station Enrollee to report
connection result after a successfully completed provisioning step. If
the peer supports this, the DPP-CONF-SENT event indicates this with a
new argument (wait_conn_status=1) and the Configurator remains waiting
for the connection result for up to 16 seconds.

Once the Enrollee reports the result, a new DPP-CONN-STATUS-RESULT event
is generated with arguments result, ssid, and channel_list indicating
what the Enrollee reported. result=0 means success while non-zero codes
are for various error cases as specified in the DPP tech spec. If no
report is received from the Enrollee, the event with "timeout" argument
is generated locally.

6e711e7ab3 mesh: Do not enable HE on 5 GHz without VHT
The commit ad9a1bfe78 ("nl80211: Share VHT channel configuration for
HE") always enforced that VHT is enabled when HE was enabled. This broke
the mesh functionality on 2.4 GHz with HE because ibss_mesh_setup_freq()
isn't setting up the VHT parameters for 2.4 GHz.

This problem was resolved for 2.4 GHz by commit df4f959988 ("nl80211:
Don't force VHT channel definition with HE"), but it is still possible
to disable VHT during the mesh/IBSS freq setup on 5 GHz - which would
result in the same problem as seen on 2.4 GHz.

The code enabling HE for IBSS/mesh must now make sure that it doesn't
enable HE when VHT could be enforced by the nl80211 driver code but
disabled by the user.

c724a0a16c EAP peer: Add a concept of a separate machine credential
This is an initial step in adding support for configuring separate user

parameters machine_identity and machine_password are similar to the

This commit alone does not change actual EAP peer method behavior as
separate commits are needed to determine when there is an explicit
request for machine authentication. Furthermore, this is only addressing
the username/password credential type, i.e., additional changes
following this design approach will be needed for certificate
credentials.

the external authentication case. This is required for roaming to a new
BSSID with driver-based-SME while the SAE processing happens with
wpa_supplicant.

e0b331d896 OWE: Update connect params with new DH attributes to the driver
A new DH public key is sent through this interface to the driver after
every successful connection/roam to a BSS. This helps to do OWE roaming
to a new BSS with drivers that implement SME/MLME operations during
roaming.

This updated DH IEs are added in the subsequent (Re)Association Request
frame sent by the station when roaming. The DH IE from the roamed AP is
given to wpa_supplicant in the roam result event. wpa_supplicant shall
further process these DH IEs to generate the PMK for the 4-way
handshake.

When required_roaming_consortium is set in a credential, station

to how it is matching for roaming_consortiums during Interworking
credentials availability check for roaming_consortium.

In the context of Hotspot 2.0 PPS MO, this means addressing matching

how HomeSP/HomeOIList/<X+>/HomeOIRequired is set (i.e., the required

The conditions for the eapol_sm_notify_eap_success(FALSE) calls did not
cover the case where eapol_sm_notify_eap_success(TRUE) had been called
based on offloaded 4-way handshake and driver notification of

result in eapSuccess and altSuccess state machine variables being left
TRUE when roaming to another BSS and that results in EAP failure if the

driver that it should offload the 802.1X handshake. However, this field
was existing and used for a different offload API. This causes
wpa_supplicant to send a connect request without the WANT_1X_HS flag and
the subsequent set-pmk is rejected causing the connection to fail. Fix
that by introducing a new flag req_handshake_offload so the offloads are
no longer entangled.

RFC 7170 has number of conflicting statements and missing details to
allow unambiguous interpretation. As such, there may be interoperability
issues with other implementations and this version should not be
deployed for production purposes until those unclear areas are resolved.

This does not yet support use of NewSessionTicket message to deliver a
new PAC (either in the server or peer implementation). In other words,
only the in-tunnel distribution of PAC-Opaque is supported for now. Use
of the NewSessionTicket mechanism would require TLS library support to

This increases the priority of the p2p-send-action radio work, i.e., the
radio work used for transmitting potentially offchannel P2P Action
frames by marking it as the next radio work to execute. This is to avoid
the delay in transmissions due to already queued offchannel radio work
items in the queue. In particular, this means not having to wait for a
pending p2p-scan radio work to be executed before the new P2P Action
frame can be transmitted. This helps in avoiding timeouts on the peer
device when a P2P Action frames is received during other activity on the

The previous implementation rejects the p2p-send-action work while there

called for it to start operation). Enhance the same to also consider any
p2p-send-action works pending in the radio work (i.e., waiting for that
wpas_send_action_cb() call).

This is considering the current behaviour of P2P to handle the state
corresponding to respective Action frame transmission:
pending_action_state. If a new P2P Action frame transmission is queued
while there is another one already in the queue, the transmit status of
the first frame is wrongly intepreted by the P2P state machine which has
already scheduled/queued another frame for transmission.

WPA_DRIVER_FLAGS_4WAY_HANDSHAKE_8021X capability flag, the EAP state
machine was not configured correctly and was waiting for EAPOL frames,
which leads to disconnection.

Fix this by reordering the if branches to set the EAPOL/EAP state
machines to success when FILS authentication was already completed.

2c129a1b71 Fix cipher suite selector default value in RSNE for DMG
According to IEEE Std 802.11-2016, 9.4.2.25 when fields of an RSNE are
not included, the default values are used. The cipher suite defaults
were hardcoded to CCMP in the previous implementation, but the default
is actually different for DMG: GCMP (per 9.4.2.25.2).

It is not possible to find out from the RSNE if the network is non-DMG
or DMG, so callers of wpa_parse_wpa_ie_rsn() need to handle this case
based on context, which can be different for each caller.

In order to fix this issue, add flags to the wpa_ie_data indicating
whether pairwise/group ciphers were included in the RSNE. Callers can
check these flags and fill in the appropriate ciphers. The
wpa_parse_wpa_ie_rsn() function still initializes the ciphers to CCMP by
default so existing callers will not break. This change also fixes some
callers which need to handle the DMG network case.

83ebf55865 wpa_supplicant: Support Multi-AP backhaul STA onboarding with WPS
The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the backhaul STA needs to add
a Multi-AP IE to the WFA vendor extension element in the WSC M1 message
that indicates it supports the Multi-AP backhaul STA role. The Registrar
(if it support Multi-AP onboarding) will respond to that with a WSC M8
message that also contains the Multi-AP IE, and that contains the
credentials for the backhaul SSID (which may be different from the SSID
on which WPS is performed).

Introduce a new parameter to wpas_wps_start_pbc() and allow it to be
set via control interface's new multi_ap=1 parameter of WPS_PBC call.
multi_ap_backhaul_sta is set to 1 in the automatically created SSID.
Thus, if the AP does not support Multi-AP, association will fail and
WPS will be terminated.

Only wps_pbc is supported.

This commit adds the multi_ap argument only to the control socket
interface, not to the D-Bus interface.

Since WPS associates with the fronthaul BSS instead of the backhaul BSS,
we should not drop association if the AP announces fronthaul-only BSS.
Still, we should only do that in the specific case of WPS. Therefore,
add a check to multi_ap_process_assoc_resp() to allow association with a
fronthaul-only BSS if and only if key_mgmt contains WPS.

3e949655cc Revert "mesh: Apply channel attributes before setup interface"
This reverts commit 2564184440.

Commit 2564184440 ("mesh: Apply channel attributes before setup
interface") triggers some channel configurations to result in leaking
memory. This seems to be caused by hapd->started not getting set when
going through a callback to start hostapd operation (e.g., when using
HT40 coex scan) due to hostapd_setup_bss() not getting called. This
results in hostapd_free_hapd_data() not clearing allocated
hapd->wpa_auth. This can be reproduced with the hwsim test case
mesh_secure_ocv_mix_legacy.

A more complete cleanup of the pending mesh patch for DFS support seems
to be needed to fix this properly, so the best approach for now is to
revert this patch and bring it back once rest of the mesh changes are
ready to be applied.

cc9c4feccc OpenSSL: Allow systemwide policies to be overridden
Some distributions (e.g., Debian) have started introducting systemwide
OpenSSL policies to disable older protocol versions and ciphers
throughout all programs using OpenSSL. This can result in significant
number of interoperability issues with deployed EAP implementations.

Allow explicit wpa_supplicant (EAP peer) and hostapd (EAP server)
parameters to be used to request systemwide policies to be overridden if
older versions are needed to be able to interoperate with devices that
cannot be updated to support the newer protocol versions or keys. The
default behavior is not changed here, i.e., the systemwide policies will
be followed if no explicit override configuration is used. The overrides
should be used only if really needed since they can result in reduced
security.

In wpa_supplicant, tls_disable_tlsv1_?=0 value in the phase1 network
profile parameter can be used to explicitly enable TLS versions that are
disabled in the systemwide configuration. For example,
phase1="tls_disable_tlsv1_0=0 tls_disable_tlsv1_1=0" would request TLS
v1.0 and TLS v1.1 to be enabled even if the systemwide policy enforces
TLS v1.2 as the minimum version. Similarly, openssl_ciphers parameter
can be used to override systemwide policy, e.g., with
openssl_ciphers="DEFAULT@SECLEVEL=1" to drop from security level 2 to 1
in Debian to allow shorter keys to be used.

In hostapd, tls_flags parameter can be used to configure similar
options. E.g., tls_flags=[ENABLE-TLSv1.0][ENABLE-TLSv1.1]

When the frame body subelement would cause the measurement report
element to exceed the maximum element size, the frame body subelement
used to be truncated. In addition, some elements were always truncated
in order to keep the reported frame body short (e.g. RSN IE).

Alternatively, IEEE P802.11-REVmd/D2.0, 9.4.2.21.7 extension to Beacon
reporting can be used: The frame body subelement is fragmented across
multiple beacon report elements, and the reported frame body fragment ID
subelement is added.

89a7cdd690 crypto: Add option to use getrandom()
According to random(4) manual, /dev/random is essentially deprecated on
Linux for quite some time:

"The /dev/random interface is considered a legacy interface, and
/dev/urandom is preferred and sufficient in all use cases, with the
exception of applications which require randomness during early boot
time; for these applications, getrandom(2) must be used instead, because
it will block until the entropy pool is initialized."

An attempt to use it would cause unnecessary blocking on machines
without a good hwrng even when it shouldn't be needed. Since Linux 3.17,
a getrandom(2) call is available that will block only until the
randomness pool has been seeded.

It is probably not a good default yet as it requires a fairly recent
kernel and glibc (3.17 and 2.25 respectively).

2fc0675683 mka: Fix lowest acceptable Packet Number (LPN) calculation and use
The purpose of the Lowest Acceptable PN (lpn) parameters in the MACsec
SAK Use parameter set is to enforce delay protection. Per IEEE Std
802.1X-2010, Clause 9, "Each SecY uses MKA to communicate the lowest PN
used for transmission with the SAK within the last two seconds, allowing
receivers to bound transmission delays."

When encoding the SAK Use parameter set the KaY should set llpn and olpn
to the lowest PN transmitted by the latest SAK and oldest SAK (if
active) within the last two seconds. Because MKPDUs are transmitted
every 2 seconds (MKA_HELLO_TIME), the solution implemented here
calculates lpn based on the txsc->next_pn read during the previous MKPDU
transmit.

Upon receiving and decoding a SAK Use parameter set with delay
protection enabled, the KaY will update the SecY's lpn if the delay
protect lpn is greater than the SecY's current lpn (which is a product
of last PN received and replay protection and window size).

f9da7505bf OCV: Include and verify OCI in SA Query frames
Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.

On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.

Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.

As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.

d514b50265 WNM: Collocated Interference Reporting
Add support for negotiating WNM Collocated Interference Reporting. This
allows hostapd to request associated STAs to report their collocated
interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.

For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".

For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".

This commit adds support for reporting changes in the collocated
interference (Automatic Report Enabled == 1 and partial 3), but not for
periodic reports (2 and other part of 3).

when the network block is configured with PMF set to required, but the

This fixes issues with drivers that use the NL80211_ATTR_USE_MFP
attribute to set expectations for PMF use. The combination of non-RSN
connection with claimed requirement for PMF (NL80211_MFP_REQUIRED) could
cause such drivers to reject the connection in OWE transition mode.

af835d75b7 FILS: Fix FILS connect failures after ERP key invalidation
If the RADIUS authentication server dropped the cached ERP keys for any
reason, FILS authentication attempts with ERP fails and the previous
wpa_supplicant implementation ended up trying to use the same keys for
all consecutive attempts as well. This did not allow recovery from state
mismatch between the ERP server and peer using full EAP authentication.

Address this by trying to use full (non-FILS) authentication when trying
to connect to an AP using the same ERP realm with FILS-enabled network
profile if the previous authentication attempt had failed. This allows
new ERP keys to be established and FILS authentication to be used again
for the consecutive connections.

20c2ea412a wpa_supplicant: Fix parsing of max_oper_chwidth
The max_oper_chwidth is parsed in wpa_config_set as INT_RANGE (see
ssid_fields). The actual parsing for INT_RANGE is done by
wpa_config_parse_int which can only store the result as full integer.

max_oper_chwidth is stored as u8 (a single byte) in wpa_ssid. This means
that on little endian systems, the least significant byte of the parsed
value are really stored in the max_oper_chwidth. But on big endian
system, the only most significant byte is stored as max_oper_chwidth.
This means that 0 is always stored because the provided range doesn't
allow any other value for systems with multi-byte-wide integers.

This also means that for common systems with 4-byte-wide integers, the
remaining 3 bytes were written after the actual member of the struct.
This should not have influenced the behavior of succeeding members
because these bytes would have been part of the padding between the
members on most systems.

Increasing its size to a full int fixes the write operations outside of
the member and allows to use the max_oper_chwidth setting on big endian
systems.

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).

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

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.

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.

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

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

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.

3031133983 mesh: Move writing of mesh_rssi_threshold inside CONFIG_MESH
Previously, the code that writes mesh_rssi_threshold to a network block
always executes, but the code that reads it from network block and the
code that initializes it to a default value in a new network block are
inside #ifdef CONFIG_MESH. As a result when writing a config file it
will write mesh_rssi_threshold (since it has a non-default value) and
later fail to read the network block.

Fix this by moving the write code under #ifdef CONFIG_MESH as well.
Note, network blocks which already have mesh_rssi_threshold because of
the bug will still fail to read after the fix.

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.

7612e65b9b mka: Add error handling for secy_init_macsec() calls
secy_init_macsec() can fail (if ->macsec_init fails), and
ieee802_1x_kay_init() should handle this and not let MKA run any
further, because nothing is going to work anyway.

On failure, ieee802_1x_kay_init() must deinit its kay, which will free
kay->ctx, so ieee802_1x_kay_init callers (only ieee802_1x_alloc_kay_sm)
must not do it. Before this patch there is a double-free of the ctx
argument when ieee802_1x_kay_deinit() was called.

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.

8d968351a0 Interworking: Add NULL checking for EAP name in phase2/autheap parameter
Add NULL checking for EAP name. If it is NULL, do not add the phase2
parameter autheap. This should not happen in practice due to earlier
checks for credential matching, but if there is a code path that would
allow this to be set, it is better to skip setting of the invalid value
and allow automatic selection of the Phase 2 parameters.

Change in any network configuration at runtime will cause flush to
PMKSA cache. For most of the network parameters if there is no change
in value, PMKSA flush is not performed except 'bssid' and 'priority'.

6136394545 Make CONFIG_MACSEC depend on IEEE8021X_EAPOL
When reducing the configuration for MACsec/MKA to the bare minimum, so
no EAP authentication, just MACsec/MKA SA use with preshared key/name,
the EAPOL engine is still needed to run the protocol for MKA. Without
any EAP authentication options the IEEE8021X_EAPOL option is not set,
resulting in a non-working Key Agreement Entity.

Therefore the CONFIG_MACSEC block needs to move up and set the
IEEE8021X_EAPOL option.
