e97d7c5a6a Only advertise MSCS and SCS in Association Request if supported by AP
Since wpa_supplicant version 2.10 the extended capabilities MSCS and SCS
are advertised in the (Re)Association Request frames.

This causes the association request to be rejected by several access
points. Issue was observed with:
- D-Link DIR600
- TP-Link AC1900
- Synology MR2200ac

To avoid this issue the extended capabilities MSCS and SCS shall only be
added if the bss also supports them. While this may not follow the exact
behavior described in IEEE 802.11, this is a reasonable compromise to
avoid interoperability issues since these capabilities cannot be used
with an AP that does not support them anyway.

Note: The Extended Capabilities element is only included in the
Association Request frames if the AP also sent its extended capabilities
(see wpas_populate_assoc_ies()) as a workaround for misbehaving APs.
This workaround exists since version 2.1.

wpa_supplicant postpones expired PMKSA deletion untillassociation is

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).

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.

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].

9025def55c wpa_supplicant: Add support for pregenerated MAC
Add new 'mac_addr' policy (3) with which supplicant expects to also
obtain 'mac_value' with pregenerated value of MAC address to be used for
given SSID.

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.

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.

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.

c6f8af507e Add option to disable SAE key_mgmt without PMF
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

2e73394426 P2P: Discount current operating frequency when scanning new connection
When scanning for a new connection, we currently optimize by scanning
all frequencies only when our MCC capabilities will allow an additional
operating frequency, and scan only the existing operating frequencies
otherwise. This is problematic when there the current operating
frequency singularly accounts for one of the shared radio frequencies
because we should be able to switch operating frequencies without adding
to the channel count. Fix this.

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,

49442194c4 SAE: Derive H2E PT while reconnecting to same SSID also
P2P connections in the 6 GHz band use SAE authentication algorithm after
getting credentials with WPS connection. During WPS connection as it
doesn't use SAE, SAE PT is not derived. After getting SAE credentials,
the STA connects to the same SSID using SAE auth algorithm. Earlier, SAE
H2E PT was not derived while connecting to the same SSID to which the
STA is connected last time. Due to this, the P2P group formation fails
for 6 GHz channels when H2E is enabled as the PT will not be setup by
the P2P client before proceeding to the SAE authentication. Same could
happen with infrastructure WPS when wps_cred_add_sae=1 is used.

Set up the SAE H2E PT while connecting to the same SSID again also to
make sure that the H2E PT is set up in the STA to derive the PWE for
successful SAE authentication. The PT derivation will be skipped in
wpa_s_setup_sae_pt() if PT is already available for that SSID.

b4f7506ff0 FILS: Flush external-PMKSA when connection fails without ERP keys
External applications can store PMKSA entries persistently and
reconfigure them to wpa_supplicant after restart. This can result in
wpa_supplicant having a PMKSA for FILS authentication without having

mechanism for dropping FILS PMKSA entries to recover from rejected

80bcd7ecd1 FILS: Flush PMKSA entries on FILS connection failure
wpa_supplicant generates both a PMKSA cache entry and ERP keys upon
successful FILS connection and uses FILS authentication algorithm for
subsequent connections when either ERP keys or a PMKSA cache entry is
available.

In some cases, like AP/RADIUS server restart, both ERP keys and PMKSA
becomes invalid. But currently when an AP rejects an association,
wpa_supplicant marks only ERP keys as failed but not clearing PMKSA.

Since PMKSA is not cleared, consecutive connection attempts are still
happening with FILS authentication algorithm and connection attempts are
failing with the same association rejection again instead of trying to
recover from the state mismatch by deriving a new ERP key hierarchy.

Clear PMKSA entries as well on association rejection from an AP to allow
the following connection attempt to go with open authentication to
re-establish a valid ERP key hierarchy. Also, since clearing PMKSA
entries on unprotected (Re)Association Response frames could allow DoS
attack (reduce usability of PMKSA caching), clear PMKSA entries only
when ERP keys exists.

ecaacb47b7 OCE: Remove AP from driver disallow list with sufficient AP RSSI
When a STA makes an association request that is rejected by an OCE AP
due to the RSSI being insufficient, the AP is added to the driver
disallow list by wpa_set_driver_tmp_disallow_list().

Once the AP increases TX power which makes the AP RSSI higher than
Association Rejection RSSI threshold, the AP is supposed to be removed
from the driver disallow list but that was not the case.

wpa_is_bss_tmp_disallowed() is called in the scan result handler, so it
is the best place to put the logic of removing the AP from the driver
disallow list with sufficient AP RSSI.

This is needed with drivers that use the temporarily disallowed BSS list
(which is currently supported only with a QCA vendor command). The
wpa_supplicant internal functionality was already taking care of this
with the wpa_is_bss_tmp_disallowed() return value even for cases where
the entry remaining in the list.

8ca330bd70 Flush pending control interface message for an interface to be removed
wpa_supplicant_ctrl_iface_deinit() was executed only if the
per-interface control interface initialization had been completed. This
is not the case if driver initialization fails and that could result in
leaving behind references to the freed wpa_s instance in a corner case
where control interface messages ended up getting queued.

Fix this by calling wpa_supplicant_ctrl_iface_deinit() in all cases to
cancel the potential eloop timeout for wpas_ctrl_msg_queue_timeout with
the reference to the wpa_s pointer. In addition, flush any pending
message from the global queue for this interface since such a message
cannot be of use after this and there is no need to leave them in the
queue until the global control interface gets deinitialized.

82a348eda4 wpa_supplicant: Don't process EAPOL frames while disconnecting
An EAPOL frame may be pending when wpa_supplicant requests to
deauthenticate. At this stage the EAP SM cache is already cleaned by
calling eapol_sm_invalidate_cached_session(). Since at this stage the
wpa_supplicant's state is still set to associated, the EAPOL frame is
processed and results in a crash due to NULL dereference.

This wasn't seen previously as nl80211 wouldn't process the
NL80211_CMD_CONTROL_PORT_FRAME, since wpa_driver_nl80211_mlme() would
set the valid_handler to NULL. This behavior was changed in commit
ab89291928 exposing this race.

Fix it by ignoring EAPOL frames while the deauthentication is in
progress.

73ebd58fc8 STA: Check driver capability to enable OCV when driver SME is used
When the driver SME is used, offloaded RSN handshakes like SA Query, GTK
rekeying, FT authentication, etc. would fail if wpa_supplicant enables
OCV in initial connection based on configuration but the driver doesn't
support OCV. To avoid such failures check the driver's capability for
enabling OCV when the driver SME used.

This commit also adds a capability flag for indicating OCV support
by the driver.
