0059fa5bae 6 GHz: Fix secondary channel setting
center_idx_to_bw_6ghz() does not return the bandwidth in MHz and as
such, the check here against 20 (MHz) is never true. The returned value
is greater than 0 for the over 20 MHz cases.

4e86692ff1 AP: Fix 6 GHz AP setup after disable-enable
Once ACS picks a channel, iface->freq and iface->conf->channel are
updated. So, AP comes up in the last operating channel when 'ENABLED'
after 'DISABLED' though ACS is configured.

But this will fail for 6 GHz APs since configured_fixed_chan_to_freq()
checks if iface->conf->channel is filled or not irrespective of ACS
configuration, and the checks inside configured_fixed_chan_to_freq()
fail the AP setup. Fix this by clearing iface->freq and
iface->conf->channel in AP setup for ACS configuration.

1491fc64a8 Define QCA vendor per-enum 64-bit pad attributes
When writing 64-bit attributes into the netlink buffer, senders may
add a padding attribute to allow the payload of the 64-bit attribute
to be 64-bit aligned. For QCA vendor attributes, currently the
attribute QCA_WLAN_VENDOR_ATTR_PAD in enum qca_wlan_vendor_attr is
defined for this purpose.

Unfortunately, when adding attributes to the netlink buffer, all
attributes at a given level of nesting must be defined in the same
enum so that they can be unambiguously parsed. This means that
QCA_WLAN_VENDOR_ATTR_PAD can only be used to pad 64-bit attributes
defined in enum qca_wlan_vendor_attr.

There are many other QCA vendor enums which define 64-bit attributes,
so add a pad attribute to all of them so that the 64-bit attributes
can be unambiguously padded.

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.

b3921db426 nl80211: Add frequency info in start AP command
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.

ec02a0e936 hostapd: Output hw_mode when using STATUS
Adding the hw_mode config parameter to the STATUS output to easier
determine the current hw_mode of an hostapd access-point. Currently
neither STATUS, GET hw_mode, nor GET_CONFIG output it.

Useful if the hostapd access point has been created with
wpa_ctrl_request() without using a *.conf file, like hostapd.conf.

c91852044d MLD STA: Add support for SAE external authentication offload to userspace
Enable MLO for SAE authentication when the driver indicates the AP MLD
address in an external authentication request. The MAC address of the
interface on which the external authentication request received will be
used as the own MLD address.

This commit does below for enabling MLO during external SAE
authentication:
- 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.

ba150059d1 FT: Store PMK-R0/PMK-R1 after EAPOL-Key msg 2/4 MIC validation
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.

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.

d9d5e55c54 DPP: Respond to GAS on the same channel it was received on
When I was testing dpp_auth_init on an AP with Enrollee on a different
channel from the AP I was getting failures. This happened on hwsim in
UML with time-travel for me. I don't recall seeing this with real
devices, presumably because of lax offchan implementation.

The DPP authentication would succeed. However the station would then try
to get configuration through a GAS request and fail.

The AP reported the following logs (grepped):

> 1614762426.860212: RX_ACTION category 4 action 10 sa 02:00:00:00:01:00 da 02:00:00:00:00:00 len 227 freq 2412

> 1614762428.861186: DPP: Timeout while waiting for Configuration Result
> 1614762428.861186: wlan0: DPP-CONF-FAILED

While the STA reported the following logs (grepped):

> 1614762426.860193: wlan1: DPP-AUTH-SUCCESS init=0
> 1614762426.860195: DPP: Stop listen on 2412 MHz

> 1614762428.861189: DPP: GAS query did not succeed

AP would still receive the GAS request on ch1 but would then try to
respond on ch11 while STA was waiting on ch1.

c46351d10e DFS: Clear cac_started when AP is disabled
When AP is started on a DFS channel and DFS is offloaded to the driver,
AP setup will be separated to two stages. In the first stage, hostapd
will set frequency and initialize BSS, then waits the driver CAC to
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
during a driver CAC procedure because some steps such as setting
freq/beacon in the first stage are skipped due to cac_started not
cleared when the AP is disabled.

Avoid this by clearing cac_started when the AP is disabled.

af1528a128 hostapd: Add RELOAD_BSS
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.

98e9d553f2 nl80211: Check previous MAC address for locally-generated-deauth
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).

b6d3fd05e3 FT: Use SHA256 to derive PMKID for AKM 00-0F-AC:3 (FT-EAP)
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.

message frame from a STA: "An SAE Confirm message, with a status code
not equal to SUCCESS, shall indicate that a peer rejects a previously
sent SAE Confirm message. An SAE Confirm message that was not
successfully verified is indicated with a status code of
CHALLENGE_FAILURE."

hostapd, however, did not use this status code for this case. In
ieee802_11.c the function sae_check_confirm() is called and in case of
verification failure (-1 is returned), the response is set to
WLAN_STATUS_UNSPECIFIED_FAILURE (status code = 1). Fix this to use
CHALLENGE_FAILURE.

b6c38cee93 Skip CAC if the driver switches channel to non-DFS
If an AP is started on a DFS channel (or any channels within its
bandwidth require DFS) and DFS is offloaded to the driver, hostapd needs
to wait for CAC to complete. But the driver may not do CAC and just
switches to a non-DFS channel instead. This would result in a failure to
start the AP because hostapd fails to receive a CAC complete event and
cannot finish interface setup.

Skip CAC and complete AP setup in the channel switch event handler for
this case.

Commit 25b52e5f83 ("FT: Extend FTE parsing for FT-SAE-EXT-KEY") used
possible MIC length iteration to try to figure out the length of the MIC
field in FTE. That was the only option available at the time, but FTE is
now being extended in IEEE 802.11-REVme to explicitly indicate the
length of the MIC field for the new FT-SAE-EXT-KEY AKM to make this
easier.

Use the new design from the approved comment resolution (*) in
REVme/D2.0 ballot CID 3135 to simplify implementation. This gets rid of
the need to pass in key length and the somewhat strange need_{r0kh,r1kh}
parameters to wpa_ft_parse_ies().

5ea7a2f545 DPP: Drop PMKSA entry if AP reject association due to invalid PMKID

This was already handled for the SME-in-the-driver case in commit commit
50b77f50e8 ("DPP: Flush PMKSA if an assoc reject without timeout is
received"), but the wpa_supplicant SME case did not have matching
processing.

Add the needed check to avoid recover from cases where the AP has
dropped its PMKSA cache entry. Do this only based on the specific status
code value (53 = invalid PMKID) and only for the PMKSA entry that
triggered this failure to minimize actions taken based on an unprotected

if NL80211_CMD_SET_PMKSA fails with ERANGE try NL80211_CMD_SET_PMKSA

than 64 bytes.

This is needed for some newer cases like DPP with NIST P-521 and
SAE-EXT-KEY with group 21. The kernel change from 48 to 64 octets is
from February 2018, so the new limit should be available in most cases

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.

ae517789fa P2P: Allow PSC channel to be used for 6 GHz BW40
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.

9c830d9178 P2P: Track peer 6 GHz capability more robustly
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.

In pairing verification, Wi-Fi Aware devices uses PASN Authentication

e1105bab89 Add QCA vendor interface support for Spatial Reuse (SR) feature
Add a new vendor sub-command to implement Spatial Reuse feature.
Userspace enables SR feature with specific configuration parameters. The
driver/firmware upon receiving the command, enables the SR feature if it
is supported by the currently connected AP. The driver may reject the
command if it cannot enable the SR with the configured parameters. The
driver sends events to userspace to indicate when SR feature is enabled
or disabled internally. Userspace can also query SR feature related
parameters and statistics from the driver/firmware as needed.
