Add support for including multiple hostapd interfaces in the same AP
MLD, i.e., all using the same underlying driver network interface.
To do so, when a new hostapd interface is added, if there is already
another interface using the same underlying network interface, associate
the new interface with the same private data object, instead of creating
a new one.
As some of the BSSs are non-first BSSs, meaning that they reuse the

handle NO_IR scenarios, such as AFC, where the channels not allowed by
AFC will have HOSTAPD_CHAN_NO_IR flag set. In this state, AP is still

Some station devices are apparently sending the EAPOL-Logoff message in
some cases before the initial authentication for WPA2/WPA3-Enterprise.
hostapd would have forced a "post EAP-Failure" disconnection in 10 ms
for such cases while still allowing the EAP authentication to try to
complete.
This is not ideal and could result in interoperability issues, so skip
the forced disconnection in the particular case where the EAPOL-Logoff
message is received before the first authentication is completed.
In addition, disconnect the STA without starting new EAP authentication
and the 10 ms delay if an EAPOL-Logoff message is received after
authentication has been completed successfully. This results in cleaner
behavior by avoiding the extra start of a new EAP authentication in a
case where the STA is going to be disconnected shortly.

conf->secondary_channel does not hold the correct value and it leads to

filled using the hostapd config he_oper_centr_freq_seg0_idx. When AP is
configured to use ACS, the hostapd config he_oper_centr_freq_seg0_idx is
not valid as the channel is not known during bring up. So using the

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.

When ACS is configured in multiple BSS case, sometimes a virtual AP
interface does not come up as the channel context information between
different BSSs of the same band does not match.
Same behavior is observed in case of multiple band/hardware under a
single wiphy, when we bring up multiple virtual interface in various
bands simultaneously and the kernel maps a random channel as it has more
than one channel context, e.g., say a 2.4 GHz channel to a 5 GHz virtual
AP interface when the start AP command is sent. This is because the
frequency information is not present in the command.
Add the frequency information into the start AP netlink command so that
the kernel maps the appropriate channel context by parsing it instead of
using a previous set channel information.

Currently invitation request wait time is very long and not needed for
sending a single Action frame only. To not interfere with other parallel
channel activities, decrease the wait time to to 150 ms in case of an
active P2P GO on the system.
In addition, if a P2P GO tries to invite a client that doesn't respond,
it will attempt to invite again after 100 ms. This is too aggressive and
may result in missing beacon transmission and affecting GO activity on
its operating channel. Increase the timeout to 120 ms, to allow enough

hostapd was previously storing the derived PMK-R0 and PMK-R1 as soon as
these keys were derived. While that is fine for most purposes, it is
unnecessary to do that so quickly and if anything were to fail before
the supplicant is able to return a valid EAPOL-Key msg 2/4, there would
not really be any real use for the derived keys.
For the special case of FT-PSK and VLAN determination based on the
wpa_psk file, the VLAN information is set in the per-STA data structures
only after the EAPOL-Key msg 2/4 MIC has been verified. This ended up
storing the PMK-R0/PMK-R1 entries without correct VLAN assignment and as
such, any use of the FT protocol would not be able to transfer the VLAN
information through RRB.
Split local storing of the FT key hierarchy for the cases using the FT
4-way handshake so that PMK-R0 and PMK-R1 are first derived and then
stored as a separate step after having verified the MIC in the EAPOL-Key
msg 2/4 (i.e., after having confirmed the per-STA passphrase/PSK was
selected) and VLAN update. This fixes VLAN information for the
wpa_psk_file cases with FT-PSK.

When AP is started on a DFS channel and DFS is offloaded to the driver,

complete. Once CAC done, in the second stage,
hostapd_setup_interface_complete() will be called again from a callback
to continue AP/channel setup.
But the driver will fail to restart AP if it is disabled/reenabled

implementations that use the EAP-FAST-MSCHAPv2, instead of the
EAP-MSCHAPv2, way of deriving the MSK for IMSK. Use that design here to
interoperate with other implementations since that seems to be direction
that IETF EMU WG is likely to go with an RFC 7170 update.
This breaks interoperability with earlier hostapd/wpa_supplicant
versions.

EAP-FAST uses a special variant of EAP-MSHCAPv2 called EAP-FAST-MSCHAPv2
in RFC 5422. The only difference between that and EAP-MSCHAPv2 is in how
the MSK is derived. While this was supposed to be specific to EAP-FAST,
the same design has ended up getting deployed with EAP-TEAP as well.
Move this special handling into EAP-MSCHAPv2 implementation so that it
can be shared for both needs.

If wpa_supplicant receives a duplicate DPP chirp over a TCP connection

When using multiple BSSes on a single radio, it is sometimes desirable
to reconfigure one BSS, without disconnecting the stations already
connected to other BSSes on the same radio.
When a BSS is reconfigured using the SET command, there is no "old"
configuration we can compare to (so we cannot compare a hash of the
configuration for example).
One possible solution would be to make the current RELOAD command
reload only the current BSS. However, that could break the workflow of
existing users. Instead, introduce a new RELOAD_BSS command, which
reloads only the current BSS.

When using MAC randomization wpa_supplicant can change the local MAC
address during roaming scenario:
1. We attach to AP1 (with MAC1/SSID1).
2. Roaming to AP2 (with MAC2/SSID2) is started:
a) we send DEAUTH(for AP1, with MAC1)
b) we change MAC to MAC2 due to randomization
c) we start authentication for AP2
d) we get notification about DEAUTH for AP1 (which we ignore)
e) we complete association with AP2
In point 2d we completely ignore the notification which later causes
problems. This happens if the deauthentication event is generated by the
local driver (e.g., due to beacon loss) instead of AP2 sending an
explicit Deauthentication frame.
The intended behavior is as follows: during roaming we generate DEAUTH
(2a) and signal this event right away. To protect from handling of our
own DEAUTH for the 2nd time supplicant marks 'ignore_next_local_deauth'
variable. In point 2d we should receive this notification and clear the
flag but this does not happen because MAC1 in the notification is not
the current MAC address (it has been changed in 2b) so this notification
is ignored as a one with a "foreign" address.
So we end up successfully at AP2 but with 'ignore_next_local_deauth'
still set which causes problems. For example if AP2 shuts down it has
been observed on some drivers that the DEAUTH notification is generated
as a local one and since we have flag to ignore it nothing is reported
over D-Bus.
To address the problem let's store the previously used MAC address and
use it for checking for foreign address (in combination with the current
one).

PMKSA caching for the FT initial mobility domain association was fully
defined in IEEE Std 802.11-2020. The state before that was unclear and
there has been interoperability issues in this area, so use of PMKSA
caching with FT-EAP has been disabled in wpa_supplicant by default.
The wpa_supplicant and hostapd implementation of PMKSA caching for FT
ended up using an earlier default mechanism (SHA-1) for deriving the
PMKID when using the FT-EAP. This does not match what got defined in
IEEE Std 802.11-2020, 12.11.2.5.2 (SHA256). It is not really desirable
to use SHA-1 for anything with FT since the initial design of FT was
based on SHA256. Furthermore, it is obviously not good to differ in
behavior against the updated standard. As such, there is sufficient
justification to change the implementation to use SHA256 here even
though this ends up breaking backwards compatibility for PMKSA caching
with FT-EAP.
As noted above, this is still disabled in wpa_supplicant by default and
this change results in PMKSA caching not working only in cases where it
has been enabled explicitly with ft_eap_pmksa_caching=1. Those cases
recover by falling back to full EAP authentication.

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

Currently only accepted MLO links information is getting parsed from
(re)association events. Add support to parse all the requested MLO links
information including rejected links. Get the rejected MLO links
information from netlink attributes if the kernel supports indicating
per link status. Otherwise get the rejected MLO links information by
parsing (Re)association Request and Response frame elements.

Make sure the elements were present before trying to parse them. This
was already done for most cases, but be consistent and check each item
explicitly before use.

The previous version was using typecasting to ignore const marking for
the input buffer to be able to clear the MIC field for MIC calculation.
That is not really appropriate and could result in issues in the future
if the input data cannot be modified. Fix this by using an allocated
copy of the buffer.

The way type and subtype of the FC field was checked does not really
work correctly. Fix those to check all bits of the subfields. This does
not really make any practical difference, though, since the caller was
already checking this.
Furthermore, use a helper function to avoid having to maintain two
copies of this same functionality.

Document in src/crypto/crypto.h that compressed point format is expected
in DER produced by crypto_ec_key_get_subject_public_key(). This is the
format needed for both SAE-PK and DPP use cases that are the current
users of this function.

For the 6 GHz opclass 132, ch for loop only allows non-PSC channels { 1,
9, 17, 25, 33, 41, 49,... } to be used. This does not match the IEEE Std
802.11ax-2021 expectation of a 6 GHz-only AP "should set up the BSS with
a primary 20 MHz channel that coincides with a preferred scanning
channel".
Increase ch by 4 to allow PSC channel to be used for 6 GHz BW40.

It's necessary to maintain knowledge of the 6 GHz capability of the
peer. Since the Device Capability field migth change between frames
depending on the context in which they are used, loooking at the last
received message might not always provide accurate information.
Add supports_6ghz bool variable in struct p2p_device, initialize it to
false and set to true if the P2P_DEV_CAPAB_6GHZ_BAND_CAPABLE bit is set
to 1 in any P2P frame that includes the P2P Capability attribute. This
boolean would not be cleared to false at any point in time so that the
info doesn't disappear dynamically.

Add a new vendor subcommand
QCA_NL80211_VENDOR_SUBCMD_MLO_PEER_PRIM_NETDEV_EVENT to send notification
to application layer about primary netdev of an MLO peer association.
Also define the attributes present in this subcommand.

Introduce a run time roam configuration for "hand off delay for RX".
This value, in milliseconds, will delay the hand off for the specified
time to receive pending RX frames from the current BSS.

struct wpas_pasn is common to both initiator and responder, so rename it
to pasn_data to avoid the "wpas_" prefix that could be seen as a
reference to wpa_supplicant (PASN initiator).

Wi-Fi Aware uses PASN handshake to authenticate peer devices. Devices
can simply verify each other for subsequent sessions as long as the keys
remain valid after authentication has been successful and pairing has
been established.
In pairing verification, Wi-Fi Aware devices uses PASN Authentication
frames with custom PMKID and Wi-Fi Aware R4 specific verification IEs.
It does not use wrapped data in the Authentication frames. This function
provides support to construct PASN Authentication frames for pairing
verification.
