8bc84fceeb Allow MLO disabled connection to legacy open/WPA2-Personal-only AP MLDs
wpa_supplicant was skipping MLD APs from network selection when the AP
advertise legacy open, WPA2-Personal-only (PSK without SAE), or PMF
disabled. However, there are already some early Wi-Fi 7 APs in the
market which advertise legacy open, WPA2-Personal-only, or PMF disabled
even though these combinations are unlikely to be allowed for Wi-Fi 7 in
the end.

To avoid connectivity issues with such APs, allow stations to connect
with MLO disabled when an AP MLD is detected to advertise legacy open,
WPA2-Personal-only (PSK without SAE), or PMF disabled.

This reverts commit 7d8b96dcfd ("wpa_supplicant: Apply same
restrictions for MLD as for 6 GHz BSS") except WEP and TKIP checks,
i.e., AP MLDs which advertise only WEP or TKIP are still skipped from
network selection.

For the SME-in-wpa_supplicant case, skip configuring MLD parameters to
the driver if the STA can connect only in legacy open,
WPA2-Personal-only, or PMF disabled mode. For the SME-in-driver case, it
is the driver's responsibility to initiate connection with MLO disabled
with such APs.

b9c3b57a99 Update AP RSNE/RSNXE to RSN state machine on driver-selected BSS cases
The driver-initiated BSS selection case and the "Network configuration
found for the current AP" case ended up clearing the RSN state machine
information on AP RSNE/RSNXE. That could result in incorrect behavior if
some key management operations depended on accurate information. For
example, this could result in not deriving the KDK as part of the PTK
derivation and failing to complete 4-way handshake if both the AP and
the STA indicated support for Secure LTF.

If the scan results for the selected BSS are available, use those to
update the RSN state machine AP RSNE/RSNXE similarly to the way this is
done with wpa_supplicant selects the BSS instead of clearing that
information in the RSN state machine.

6972b0fa2b OWE: Update transition mode information on selecting a new BSS
It is possible for a new BSS entry to be added for the
hidden-SSID-OWE-BSS when running a new scan after having previously
learned the hidden SSID during a previous OWE connection attempt. That
new entry would not necessarily have the WPA_BSS_OWE_TRANSITION flag set
and that would result in not being able to recognize the appropriate OWE
profile when checking the association event against the transition mode
configuration.

Fix this by updating the BSS entry for OWE transition mode information
for the cases where this might happen.

07a7bcd7ea WMM: Advertise support for 16 PTKSA replay counters for non-AP STA
In theory, each device that supports WMM (or the IEEE 802.11 QoS for
that matter) is expected to advertise how many replay counters it
supports and the peer device is supposed to use that information to
restrict the total number of different MSDU priorities (AC/UP) that
might be used. In practice, this is not really done in deployed devices
and instead, it is just assumed that everyone supports the eight
different replay counters so that there is no need to restrict which
MSDU priorities can be used.

hostapd implementation of WMM has advertised support for 16 PTKSA replay
counters from the beginning while wpa_supplicant has not had any code
for setting the supported replay counter fields in RSNE, i.e., has left
the value to 0 which implies that only a single replay counter is
supported. While this does not really result in any real issues with
deployed devices, this is not really correct behavior based on the
current IEEE 802.11 standard and the WMM specification.

Update wpa_supplicant to use similar design to the hostapd RSNE
generation by setting the number of supported PTKSA replay counters to
16 whenever WMM is enabled. For now, this is done based on the
association being for HT/VHT/HE/EHT and also based on the AP supporting
WMM since it is much more likely for the local device to support WMM and
eight replay counters (which can be indicated only with the value that
implies support for 16 counters since there is no separate value for 8).

6b9c86466c nl80211: Replace the channel flags for VHT support
The flags that indicate that a channel is allowed for 80/160 MHz use
are divided according to the position of the control channel (e.g.,
HOSTAPD_CHAN_VHT_10_70, HOSTAPD_CHAN_VHT_30_50, etc.).

However, the position of the control channel does not add any extra
regulatory information because when trying to use a 80/160 MHz channel
all the desired bandwidth has to be allowed for 80/160 MHz use,
regardless of the control channel position.

In addition, these flags are set only if the driver reports one
regulatory rule that allows the entire 80/160 MHz bandwidth.
However, even when a 80/160 MHz channel is allowed, in some cases the
bandwidth will be split into several regulatory rules because
different segments of the bandwidth differ in other flags (that don't
affect the use of the bandwidth for VHT channels). So, in such cases
these flags will not be set, although VHT channels are allowed.

As the result, VHT channels will not be used although they are allowed
by the regulatory domain.

Fix this by introducing new flags that indicate if a 2 0MHz channel is
allowed to be used as a part of a wider (80/160 MHz) channel.
The new flags are set for each 20 MHz channel independently and thus
will be set even if the regulatory rules for the bandwidth are split.

A 80/160 MHz channel is allowed if all its 20 MHz sub-channels are
allowed for 80/160 MHz usage.

the current interface is actually in active PBC mode. Furthermore, the
wpa_s->wps_overlap variable needs to be cleared in additional places to
avoid leaving it set indefinitely.

This was found with the following test case sequence:
dbus_wps_pbc_overlap dbus_p2p_two_groups

bdbb6e0035 wpa_supplicant: Handle MAC address randomization changes for same ESS
When MAC address randomization settings change we should use a new MAC
address even if we are associating to the same ESS.

For example, consider this scenario:
- hardware MAC is being used,
- we disconnect from the network,
- policy/style is changed via D-Bus to turn randomization on,
- we reconnect to the same network.

In the last step a randomized MAC address should be used.

Changes to the randomization settings include both changes to the
policy/style to be used and changes to the pregenerated MAC address
value in case of mac_addr==3.

4bd1efe073 dbus: Do not bring down primary interface when removing created AP interface
If the CreateInterface command was used to create a virtual AP
interface, deleting this interface using the RemoveInterface command was
also bringing down the primary interface.

wpa_supplicant never uses hostapd style multi-BSS setup with
type=WPA_IF_AP_BSS and setup_ap=1 to if_add() when creating an AP
interface in wpa_driver_nl80211_if_add(), so it should not go through
the multi-BSS tear down procedure in wpa_driver_nl80211_if_remove(). The
virtual AP resources init and deinit are well handled in
wpa_driver_nl80211_init() and wpa_driver_nl80211_deinit().

Collapse the interface type to WPA_IF_STATION for the D-Bus interface to
skip the multi-BSS cleanup procedure. This is inline with the control
interface design. Add comments before the code to avoid confusion.

d8d2b3a338 Implement read-only mode for SSIDs from the additional config (-I)
On NixOS[1] - a Linux distribution which allows to configure a full OS
declaratively - it's possible to configure SSIDs for `wpa_supplicant`
like this:

    networking.wireless.networks = {
      myssid = {
        pskRaw = "<redacted>";
      };
    };

It's also possible to add networks "imperatively" using `wpa_gui` or
`wpa_cli`. However it's not possible to do both because if the first
option is used, NixOS creates a read-only symlink at
`/etc/wpa_supplicant.conf` and then it's not possible for
`wpa_supplicant` anymore to write to it.

This patch aims to help us changing this: while "declarative" SSID
configuration can be quite useful, it's a bad idea for e.g. sensitive
stuff like a WPA2 enterprise network.

The original idea was to use `-I`[2] for immutable configs (including
"declarative" networks) on NixOS and `-c /etc/wpa_supplicant.conf` for
anything "imperative".

However this doesn't really work out because if a wifi network from a
config file specified with `-I` is changed by e.g. `wpa_gui`, it's
silently overwritten in `/etc/wpa_supplicant.conf` (specified with
`-c`) which is IMHO unintuitive (in our case at least). This patch
basically declares each network defined in a config file passed via `-I`
to `wpa_supplicant` as "read-only" and doesn't write these "read-only"
networks to `/etc/wpa_supplicant.conf`.

A bit more context can be found on GitHub in the PR where I implemented
this[3].

The main difference between this policy and policy 1 is the ability to
control persistence of the MAC address used.  For example if there is
a requirement to always use the same (but random) MAC address for given
SSID (even if user removes/forgets the network) this could be handled
outside of the wpa_supplicant by using some SSID based hashing scheme to
generate MAC (or by just storing the randomly generated one) and
providing it to wpa_supplicant together with mac_addr=3 policy.

roaming_consortium option) and one required home OI (with
required_roaming_consortium option). To improve the compliance with
Passpoint specification, add the support for multiple home and required
OIs.

The lists of OIs are provided using two new configuration options
home_ois and required_home_ois that expect a list of OIs formatted as
the roaming_consortiums list. It allows to keep the old options to avoid
breaking currently running configurations and better fits the vocabulary
used in the spec.

The OI match algorithm is updated to implement the behavior described in
Passpoint specification v3.2 section 9.1.2 (Home OIs nodes description
PerProviderSubscription/<X+>/HomeSP/HomeOIList/<X+>).

received, even if there might have been a more recent Beacon frame with
an updated WPS IE. This could result in using stale information about

Prefer WPS IE from a Beacon frame over the default selection of Probe
Response frame (if one has been received) in cases where the Beacon

65c8633d90 Allow a lower priority BSS to be tried after network disabling
If a higher priority BSS has invalid security parameters, e.g., an
invalid SAE password, and a lower priority BSS is discovered only after
the local network profile has been temporarily disabled, the BSSID
ignoring mechanism is not sufficient to allow the lower priority BSS to
be tried and all consecutive attempts will continue to use the higher
priority BSS. This might prevent connection in some unexpected cases
with invalid network configuration.

Extend BSSID ignoring mechanism to work in this type of a case by
ignoring the BSSID that resulted in disabling the SSID temporarily
during the first connection attempt after having re-enabled the SSID.
This allows a lower priority BSS, if any is available in scan results,
to be tried next to see if it might have working security parameters.

Add the needed check to avoid recover from cases where the AP has

bbe5f0c1eb FT: Do not try to use FT protocol between mobility domains
wpa_supplicant has support for only a single FT key hierarchy and as
such, cannot use more than a single mobility domain at a time. Do not
allow FT protocol to be started if there is a request to reassociate to
a different BSS within the same ESS if that BSS is in a different
mobility domain. This results in the initial mobility domain association
being used whenever moving to another mobility domain.

While it would be possible to add support for multiple FT key hierachies
and multiple mobility domains in theory, there does not yet seem to be
sufficient justification to add the complexity needed for that due to
limited, if any, deployment of such networks. As such, it is simplest to
just prevent these attempts for now and start with a clean initial
mobility domain association.

Add the `sae_check_mfp` global option to limit SAE when PMF will
not be selected for the connection.
With this option SAE is avoided when the hardware is not capable
of PMF due to missing ciphers.
With this option SAE is avoided on capable hardware when the AP
does not enable PMF.

Allows falling back to PSK on drivers with the
WPA_DRIVER_FLAGS_SAE capability but do not support the BIP cipher
necessary for PMF. This enables configurations that can fall back
to WPA-PSK and avoid problems associating with APs configured
with `sae_require_mfp=1`.

Useful when `pmf=1` and `sae_check_mfp=1` are enabled and networks
are configured with ieee80211w=3 (default) and key_mgmt="WPA-PSK SAE".
In this configuration if the device is unable to use PMF due to
lacking BIP group ciphers it will avoid SAE and fallback to
WPA-PSK for that connection.

The initial wpa_drv_get_mlo_info() implementation cleared only the
valid_links information within struct driver_sta_mlo_info before trying
to fetch the information from the driver. While this is likely going to
work fine in practice, this can result in static analyzer warnings on
use of uninitialized memory (e.g., mlo.assoc_link_id could have been
read if wpa_s->valid_links was set to a nonzero value). In any case, it
is better to avoid such unnecessary warnings by clearing the full data

48c620829c Update PSK after cross AKM roaming to WPA-PSK when driver's SME in use
4-way handshake was failing after the driver roam from SAE to WPA-PSK
due to wpa_sm having an old PMK which was generated during previous SAE
connection.

To fix this update PSK to wpa_sm when AKM changes from SAE to WPA-PSK
for the target AP to have a correct PMK for 4-way handshake. Also,
update PSK to the driver when key management offload is enabled.

encoding profiles are added into wpa_supplicant to make sure the
connection succeeds. In this situation, wpa_supplicant_select_network()

Android monitors the WPA_EVENT_STATE_CHANGE event to get the SSID and
BSSID. When connecting to a Chinese SSID, in case of association
rejection happens, Android will report null SSID to OEM APP because
current_ssid is updated after wpa_supplicant_set_state(wpa_s,

3c2fbe9f56 Discard unencrypted EAPOL-EAP when TK is set and PMF is enabled
RSN design is supposed to encrypt all Data frames, including EAPOL
frames, once the TK has been configured. However, there are deployed
implementations that do not really follow this design and there are
various examples from the older uses of EAPOL frame where those frames
were not encrypted. As such, strict filtering of unencrypted EAPOL
frames might results in undesired interoperation issues.

However, some of the most important cases of missing EAPOL frame
encryption should be possible to handle without causing too significant
issues. These are for cases where an attacker could potentially cause an
existing association to be dropped when PMF is used. EAP-Request is one
potential candidate for such attacks since that frame could be used to
initiate a new EAP authentication and the AP/Authenticator might not
allow that to complete or a large number of EAP-Request frames could be
injected to exceed the maximum number of EAP frames. Such an attack
could result in the station ending up disconnecting or at minimum,
getting into somewhat mismatching state with the AP.

Drop EAPOL-EAP frames when it is known that it was not encrypted but
should have been and when PMF is enabled. While it would be correct to
drop this even without PMF, that does not provide any significant
benefit since it is trivial to force disconnection in no-PMF cases. It
should also be noted that not all drivers provide information about the
encryption status of the EAPOL frames and this change has no impact with
drivers that do not indicate whether the frame was encrypted.

566ce69a8d EAP peer: Workaround for servers that do not support safe TLS renegotiation
The TLS protocol design for renegotiation was identified to have a
significant security flaw in 2009 and an extension to secure this design
was published in 2010 (RFC 5746). However, some old RADIUS
authentication servers without support for this are still used commonly.

This is obviously not good from the security view point, but since there
are cases where the user of a network service has no realistic means for
getting the authentication server upgraded, TLS handshake may still need
to be allowed to be able to use the network.

OpenSSL 3.0 disabled the client side workaround by default and this
resulted in issues connection to some networks with insecure
authentication servers. With OpenSSL 3.0, the client is now enforcing
security by refusing to authenticate with such servers. The pre-3.0
behavior of ignoring this issue and leaving security to the server can
now be enabled with a new phase1 parameter allow_unsafe_renegotiation=1.
This should be used only when having to connect to a network that has an
insecure authentication server that cannot be upgraded.

The old (pre-2010) TLS renegotiation mechanism might open security
vulnerabilities if the authentication server were to allow TLS
renegotiation to be initiated. While this is unlikely to cause real
issues with EAP-TLS, there might be cases where use of PEAP or TTLS with
an authentication server that does not support RFC 5746 might result in
a security vulnerability.

Add support for IMSI privacy in the EAP-SIM/AKA peer implementation. If
the new wpa_supplicant network configuration parameter imsi_privacy_key
is used to specify an RSA public key in a form of a PEM encoded X.509v3
certificate, that key will be used to encrypt the permanent identity
(IMSI) in the transmitted EAP messages.

734fa392f7 MBO: Check association disallowed in Beacon frames, if newer
When a station receives either a Beacon frame or a Probe Response frame
from an AP that contains an MBO element with the Association Disallowed
attribute, the station should prevent association to that AP. When using
passive scanning, it is possible for the scan results to contain the
latest information in the Beacon frame elements instead of the Probe
Response frame elements. That could result in using old information and
not noticing the AP having changed its state to disallowing new
associations.

Make it more likely to follow the AP's change to disallow associations
by checking the Beacon frame elements instead of Probe Response frame
elements if the scan results are known to contain newer information for
the Beacon frame.

0adc67612d wpa_supplicant: Use unique IDs for networks and credentials

wpa_config_read() function is called, which is fine as long as it is
only called once. However, this is not the case when using both the -c

This is a problem because the GUI, since commit eadfeb0e93 ("wpa_gui:

(and increasing), and might get into an infinite loop otherwise.

This is solved by simply making the variables static.

5b093570dc D-Bus: Add 'wep_disabled' capability
Since commit 200c7693c9 ('Make WEP functionality an optional build
parameter'), WEP support is optional and, indeed, off by default.

The distributions are now catching up and disabling WEP in their builds.
Unfortunately, there's no indication prior to an attempt to connect to a
WEP network that it's not going to work. Add a capability to communicate
that.

Unlike other capabilities, this one is negative. That is, it indicates
lack of a WEP support as opposed to its presence. This is necessary
because historically there has been no capability to indicate presence
of WEP support and therefore NetworkManager (and probably others) just
assumes it's there.

3a157fe92f dbus: Set CurrentAuthMode to INACTIVE only if network is not selected
CurrentAuthMode should be set as a real auth type when authentication is
in progress. wpa_supplicant has a property "State" which indicates the
authentication stage already. I think setting auth mode as "INACTIVE" in
all auth progress stages is not a good idea, because sometimes we need
to handle this connection according to the auth type even when
authentication is not complete. For example, NetworkManager may recall
ask-password-dialog when auth mode is "wpa-psk" and "sae", try next
access point when auth mode is "EAP-xx" when password is incorrect.
Since "CurrentAuthMode" is set as "INACTIVE" in all not fully completed
situations, we do not know how to handle it.

build target libwpa_client.so is not built regardless of whether the
option CONFIG_BUILD_WPA_CLIENT_SO is set or not. This happens because
this config option is used before it is imported from the configuration
file. Moving its use after including build.rules does not help: the
variable ALL is processed by build.rules and further changes are not
applied. Similarly, option CONFIG_NO_WPA_PASSPHRASE also does not work
as expected: wpa_passphrase is always built regardless of whether the
option is set or not.

Re-enable these options by adding both build targets to _all
