When using mesh we have incoherent
MESH-PEER-CONNECTED/MESH-PEER-DISCONNECTED messages when we restart one
of the devices without disconnecting it first. Sometimes we have the
right behavior, a peer disconnect and then a peer connect, sometimes we
only have a a peer connected without a peer disconnected first, and
sometimes we have nothing at all.
As the plink count seem to be correctly tracked and because we only send
the connected event on plink count increase, lets send the peer
disconnected event on plink count decrease.

The previous PEAP client behavior allowed the server to skip Phase 2
authentication with the expectation that the server was authenticated
during Phase 1 through TLS server certificate validation. Various PEAP
specifications are not exactly clear on what the behavior on this front
is supposed to be and as such, this ended up being more flexible than
the TTLS/FAST/TEAP cases. However, this is not really ideal when
unfortunately common misconfiguration of PEAP is used in deployed
devices where the server trust root (ca_cert) is not configured or the
user has an easy option for allowing this validation step to be skipped.
Change the default PEAP client behavior to be to require Phase 2
authentication to be successfully completed for cases where TLS session
resumption is not used and the client certificate has not been
configured. Those two exceptions are the main cases where a deployed
authentication server might skip Phase 2 and as such, where a more
strict default behavior could result in undesired interoperability
issues. Requiring Phase 2 authentication will end up disabling TLS
session resumption automatically to avoid interoperability issues.
Allow Phase 2 authentication behavior to be configured with a new phase1
configuration parameter option:
'phase2_auth' option can be used to control Phase 2 (i.e., within TLS
tunnel) behavior for PEAP:
* 0 = do not require Phase 2 authentication
* 1 = require Phase 2 authentication when client certificate
(private_key/client_cert) is no used and TLS session resumption was
not used (default)
* 2 = require Phase 2 authentication in all cases

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.

The driver-initiated BSS selection case and the "Network configuration

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.

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).

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.

While checking for stale BSSes, the current time is used as a basis and
then based on age the stale check time is calculated, but if this is
done too early in the boot and if either BOOTTIME/MONOTONIC (the one
Zephyr uses by default) are used then the stale check time underflows
and goes to future causing active BSS entries in the scan to be treated
as stale and flushed.
Fix this by adding a check before calculating stale time and ignore this
check till the system reaches the BSS expiration time (this would never
happen with REALTIME clock).

It was possible to hit a case where the SAE PT had not yet been derived,
e.g., when using P2P group re-invocation. Update PT use at the time

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].

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.

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

During cross SSID roaming wpa_supplicant ended up using the default

To avoid this skip copying the default RSNE/RSNXE if the driver

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.

It is possible for a Controller to receive a copy of its own PKEX
Exchange Request in the case where the Controller is initiating a PKEX
exchange through a Relay. The Configurator role in the device would have
a matching PKEX code in that case and the device might reply as a PKEX
responder which would result in going through the exchange with the
Controller device itself. That is clearly not desired, so recognize this
special case by checking whether the Encrypted Key attribute value
matches a pending locally generated one when processing a received PKEX
Exchange Request.

We are not supposed to reuse these without being explicitly requested to
perform PKEX again. There is not a strong use case for being able to
provision an Enrollee multiple times with PKEX, so this should have no
issues on the Enrollee. For a Configurator, there might be some use
cases that would benefit from being able to use the same code with
multiple Enrollee devices, e.g., for guess access with a laptop and a
smart phone. That case will now require a new DPP_PKEX_ADD command on
the Configurator after each completion of the provisioning exchange.

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.

Send the status code from the AP authentication response instead of
sending the hardcoded WLAN_STATUS_UNSPECIFIED_FAILURE when the external
SAE authentication failure is due to an explicit rejection by the AP.
This will allow the driver to indicate the correct status in connect
response.
For example, an AP can send WLAN_STATUS_AP_UNABLE_TO_HANDLE_NEW_STA in
SAE authentication response. With this change the driver gets the real
status for the SAE authentication failure and it can fill the correct
status in the connect response event.

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.

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.

elements if the scan results are known to contain newer information for
