5025047ac3 Fix use after free warning introduced by gcc 12.1
gcc 12.1 complains about using pointer after realloc as it could
potentially be moved/freed, causing any uses after UB.

Fix this by doing checks before realloc and use those statuses and
update with new BSS.

c84388ee4c Compile-time config for dynamically loading libraries in wpa_supplicant
Prevent loading arbitrary executable code based on config at runtime,
while allowing libraries to be specified at compile time when they are
known in advance.

Add the ability to configure libraries to load at compile time.
	* CONFIG_PKCS11_ENGINE_PATH - pkcs11_engine library location.
	* CONFIG_PKCS11_MODULE_PATH - pkcs11_module library location.
	* CONFIG_OPENSC_ENGINE_PATH - opensc_engine library location.

Add flags with the ability to set each of the libraries to NULL and
prevent loading them at runtime.
	* CONFIG_NO_PKCS11_ENGINE_PATH - prevents loading pkcs11_engine
	  library.
	* CONFIG_NO_PKCS11_MODULE_PATH - prevents loading pkcs11_module
	  library.
	* CONFIG_NO_OPENSC_ENGINE_PATH - prevents loading opensc_engine

0776c51ed7 DPP: Handle wpas_dpp_connected() processing in eloop callback
wpas_dpp_connected() is called from wpa_supplicant_set_state(), i.e.,
from the middle of processing of the post 4-way handshake steps. Sending
a DPP Public Action frame at that point can delay other operations, so
allow those steps to be completed first before sending out the DPP
connection status result.

5c5f86900b DPP: Start next auth init from driver event to avoid race condition
It looks like mac80211 ROC handling can end up postponing offchannel TX
operation by the previously started and already canceled wait time if
the new NL80211_CMD_FRAME is issued immediately after
NL80211_CMD_FRAME_WAIT_CANCEL. Make this more robust by waiting for the
driver event that indicates completion of the cancel operation (i.e.,
NL80211_CMD_FRAME_WAIT_CANCEL as an event) before issuing
NL80211_CMD_FRAME for another channel. If the driver event is not
received within 10 ms, start the operation anyway to avoid unexpected
behavior if there are drivers that do not end up notifying end of the
wait.

This fixes some issues with authentication initiation for cases where
multiple channels are iterated. This can also significantly speed up
that process.

544801d74c wpa_supplicant: Add channel 140 to ht40plus allowed list for mesh/IBSS
When channel 140 is configured in mesh, interface fails to come up due
to channel bond (136,140). Since Channel 136 is not HT40+ capable,
validation for HT channel bonding fails when it checks whether first
channel in the bond (channel 136) is HT40+ capable.

In mesh, during channel setup, secondary channel offset for the
configured channel will be selected as +1 if primary channel is capable
of HT40+. In current code, channel 140 is not allowed as HT40+ and hence
secondary channel offset is selected as -1, which makes 136 as secondary
channel. But channel 136 is not HT40+ supported and fails in channel
bonding validation.

Add 140 to HT40+ allowed list as HT40+ is supported for the channel.

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.

a5d0bb42a2 Reduce delay between Association Request and Association Response
There is a delay between sending Association Response frame after having
received Association Request frame, due to the fact that between
receiving the request and sending the response the Beacon frame contents
is updated, after analyzing inputs from the STA. There may be several
updates if multiple fields need to change. This can cause issues with
some devices in noisy environments with many BSSs and connected STAs.

Optimize this by updating the beacon only once, even if there are
multiple reasons for updates.

42add3c27b Scan 6 GHz channels after change to 6 GHz-allowed regdom
Drivers will often report regdom changes in the middle of a scan if they
detect during that scan that the regulatory domain has changed. If this
happens and we enter a regdom that supports 6 GHz channels when the
previous one didn't (this often happens in 6 GHz-capable regdoms for
devices after suspend/resume), immediately trigger a 6 GHz-only scan if
we were not able to connect to an AP on a legacy band.

This should significantly improve connection time to 6 GHz AP after
regdom has been reset.

2bd8887e9f P2P: Pass the known BSSID to the driver to optimize scan time
After GO negotiation is completed, the P2P Client needs to scan the GO
before connecting. Only SSID was specified for this and the driver still
might need to scan all channels which wastes time. wpa_supplicant can
pass the known BSSID in the scan request in additional P2P cases and
this allows the driver sto stop the scan once the specific BSSID is
found. This helps reduce some time for P2P connection.

8e6485a1bc PEAP client: Update Phase 2 authentication requirements
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

199b44213c MLD STA: Allow auth frames without ML IE for failure status codes
In some cases like unknown-group rejection, AP MLD can't parse the
received Authentication frame to the point of the Multi-Link element if
the group used by the peer is unknown to the AP MLD.

In such cases, AP MLD not including Multi-Link element in rejection
Authentication frames can be considered as standard compliant since AP
MLD doesn't know whether the received Authentication frame has
Multi-Link element or not.

To avoid connection issues in such cases, don't reject Authentication

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.

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.

- Use MLD addresses for SAE authentication.
- Add Basic Multi-Link element with the own MLD address in SAE
  Authentication frames.
- Send SAE Authentication frames with the source address as the own MLD
  address, destination address and BSSID as the AP MLD address to the
  driver.
- Validate the MLD address indicated by the AP in SAE Authentication
  frames against the AP MLD address indicated in external authentication
  request.
- Store the PMKSA with the AP MLD address after completing SAE
  authentication.

72b8193f41 MACsec: Remove EAP Session-Id length constraint
The initial MACsec implementation required the EAP Session-Id to be at
least 65 octets long and by truncating the value to that length, the
practical limit of functional cases was limited to that exact length of
65 octets. While that happens to work with EAP method that use TLS, it
does not work with most other EAP methods.

Remove the EAP Session-Id length constraint and allow any length of the
Session-Id as long as the EAP method provides one. In addition, simplify
this be removing the unnecessary copying of the Session Id into a new
allocated buffer.

12de8112b7 Fix BSS age underflow
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,

authentication is started, if needed, to avoid this. While this is not
really ideal from the externally observable timing view point, this is

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.

If the CreateInterface command was used to create a virtual AP

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.

the event with additional metadata if it's generated in a single place.

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.

50a9b7d3d3 P2P: Include only 6 GHz PSCs in full scan
As P2P GOs are not expected to be collocated, i.e., they are not
expected to be announced in the RNR element of other APs, they can
operate only on preferred scanning channels (PSCs).

When performing a full scan for P2P discovery, include only the 6 GHz
PSCs (if supported) to avoid scanning channels on which P2P GOs are not
expected to reside.

While at it also fix couple of places that missed including 60 GHz
channels in P2P full scan.

2afb9b1a58 dbus: Add dbus notify when wpa_s->key_mgmt changes
For WPA2/WPA3 authentication mode, wpa_supplicant needs to notify
CurrentAuthMode property change when wpa_s->key_mgmt changes, so
NetworkManager can judge whether it needs to request a password based on
this.

Call wpas_notify_auth_changed() when starting a new connection item,
i.e., after having updated wpa_s->key_mgmt.

4163860605 Mark authorization completed on driver indication during 4-way HS offload
In case of drivers supporting 4-way handshake offload, mark port
authorized and state completion only if the driver advertizes authorized
state in the connect event. Otherwise there are fair chances of the
driver port authorization API getting called while 4-way handshake is in
progress at the lower layer.

In order to avoid this possible race condition always update port
authorization and supplicant state WPA_COMPLETED setting from
EVENT_PORT_AUTHORIZED context when the driver is done with the 4-way
handshake.
