f32f99df11 P2P: Send response frame on channel where the request is received
The rx_freq of Public Action frame was not maintained by the GO and the
GO always sent the response on the operating channel. This causes
provision discovery failure when a P2P Device is sending a PD Request on
a 2.4 GHz social channel and the GO is responding on a 5 GHz operating
channel.

Save the rx_freq and use it for GO to sent the response. This extends
commit c5cc7a59ac ("Report offchannel RX frame frequency to hostapd")

ff7e403f06 Fix channel switch wrapper when switching from HT to VHT/HE
Because ieee80211ac and ieee80211ax were not updated before channel
switch is done, hostapd didn't build the Channel Switch Wrapper element
when it switched from HT to bandwidth more than 40 MHz of VHT/HE. fix
this by allowing hostapd_eid_wb_chsw_wrapper() to determine internally
when the element needs to be added based on the new channel instead of
the old configuration.

GHz AP(s) are set. This is required for 6 GHz out-of-band discovery so
that lower band Beacon frames will include RNR element with 6 GHz AP

41ec97cd09 HE: Use a random BSS Color if not defined in the config file
Commit 0cb39f4fd5 ("HE: Extend BSS color support") sets the BSS Color
default value to 1 as "Interoperability testing showed that stations
will require a BSS color to be set even if the feature is disabled."

A new interop issue was observed with hardcoded BSS color value of 1:
- REF device using one interface (e.g., wlan0) to connect to an HE
  AP, whose BSS color is enabled and value is 1.
- REF device using another interface (e.g., p2p0) to connect to a
  P2P GO using BSS color default settings.
  (i.e., BSS color disabled and value is 1).
- REF device checks both AP's and P2P GO's BSS Color values even though
  GO's BSS color is disabled. This causes collision of the BSS
  color somehow causing RX problems.

For DUT as a P2P GO, its firmware uses default BSS color value 1 from
wpa_supplicant, then triggers a timer (e.g., 120 s) to update its BSS
color values based on its neighboring BSSes. To reduce the likelihood of
BSS color collision with REF device before that, use a random BSS Color
if not defined in the config file.

1071f75395 DPP2: Fix channel 6 inclusion for chirping with non-2 GHz interfaces
When the driver provides a list of supported modes, hostapd ended up
adding channel 6 even if the 2.4 GHz mode was not included. This
resulted in incorrect behavior of trying to transmit on a not supported
channel in case of 5 GHz only radios.

Fix this by adding the channel 6 by default only if the driver does not
provide a list of supported modes. Whenever the supported modes are
available, only add this channel if it is explicitly listed as an
enabled channel.

This is similar to an earlier wpa_supplicant change in commit
8e5739c3ac ("DPP2: Check channel 6 validity before adding it to chirp
channel list").

9557ba336b AP: Don't increment auth_transaction upon SAE authentication failure
IEEE Std 802.11-2016, 12.4.7.6 specifies:

An SAE Commit message with a status code not equal to SUCCESS shall
indicate that a peer rejects a previously sent SAE Commit message.

An SAE Confirm message, with a status code not equal to SUCCESS, shall
indicate that a peer rejects a previously sent SAE Confirm message.

Thus when SAE authentication failure happens, authentication transaction

84f8947735 PTKSA: Fix a potential hostapd memory leak during reconfiguration
Some of the reconfiguration cases (e.g., with WPS reconfiguration
enabling WPA/WPA2) might end up calling hostapd_setup_wpa() twice
without calling hostapd_deinit_wpa() in the middle. This would have
resulted in a memory leak since the PTKSA cache was being reinitialized
without freeing previous memory allocation.

Fix this by making PTKSA cachine initialization independent of
hapd->wpa_auth so that reinitialization does not happen in a manner that
would have overridden the old hapd->ptksa pointer without freeing the
referenced resources.

09fb9b0cb0 DFS offload: Use hostapd_is_dfs_required() to check if DFS required
hostapd_handle_dfs_offload() is the DFS handler for the offloaded case,
in which ieee80211_is_dfs() is used to check if the configured frequency
requires DFS or not.

When the configured channel width is not 20 (e.g., 160),
ieee80211_is_dfs() will not checked adjacent freqs, so it possibly makes
wrong conclusion for whether DFS is required.

hostapd_is_dfs_required() does similar thing with ieee80211_is_dfs()
except it supports checking whether the configured frequency and its
adjacent frequencies require DFS. So hostapd_is_dfs_required() is a more
robust and better option than ieee80211_is_dfs() to check DFS.

The issue is hostapd_is_dfs_required() is for non-offload case due to
the check of the configuration parameter ieee80211h. Add a check for
WPA_DRIVER_FLAGS_DFS_OFFLOAD to make it support the DFS offload case
(i.e., ieee80211h=0) as well.

For example, configuring the AP to start at freq=5240 with channel width
160:
- Existing hostapd checks freq=5240 is non-DFS, hence skip DFS CAC and
  transition to AP-Enabled which volatiles DFS-RADAR detection.

  LOG: "hostapd : hostapd_handle_dfs_offload: freq 5240 MHz does not
        require DFS. Continue channel/AP setup"

- This commit checks freq=5240 and its adjacent freqs are DFS required,
  hence remains in DFS state until DFS CAC completed.

        DFS for 4 chans"

c25b50306e hostapd: Reject 40 MHz channel config if regulatory rules do not allow it
When regulatory rules are configured not to support 40 MHz channels on
the 2.4 GHz band, hostapd_is_usable_chans() still allowed 40 MHz
channels (i.e., 1-9) to be used with ht_capab=[HT40+][HT40-].

Looking into hostapd_is_usable_chans():
1) Validate primary channel using hostapd_is_usable_chan()
2) Try to pick a default secondary channel if hostapd_is_usable_chan()
3) Try to pick a valid secondary channel if both HT40+/HT40- set, and
   further validate primary channel's allowed bandwidth mask.
4) Return channel not usable.

For example, for the 2.4 GHz channel 9 in Japan, its default secondary
channel is 13, which is valid per hostapd_is_usable_chan(), so step (2)
returns channel usable.

Add a more strict check to step (2) to clearly reject 40 MHz channel
configuration if regulatory rules do not allow the 40 MHz bandwidth,
which is similarly done in commit ce6d9ce15b ("hostapd: Add supported
channel bandwidth checking infrastructure").

end up resulting in undesired behavior. As such, drop such frames
instead of interpreting them as valid SA Query Request/Response.

827b43b3ca RADIUS client: Support SO_BINDTODEVICE
Allow the RADIUS client socket to be bound to a specific netdev. This
helps hostapd work better in VRF and other fancy network environments.

dc72854fe2 Fix handle_auth_cb() message length check regression
Reordering of code in handle_auth_cb() when adding support for full
station state messaged up frame length checks. The length was originally
tested before looking at the payload of the frame and that is obviously
the correct location for that check. The location after those full state
state changes was after having read six octets of the payload which did
not help at all since there was no addition accesses to the payload
after that check.

Move the payload length check to appropriate place to get this extra
level of protection behaving in the expected manner. Since this is a TX
status callback handler, the frame payload is from a locally generated
Authentication frame and as such, it will be long enough to include
these fields in production use cases. Anyway, better keep this check in
working condition.

6f92f81dac AP: Check driver's capability to enable OCV when driver SME is used
When the driver SME is used, offloaded handshakes which need Operating
Channel Validation (OCV) such as SA Query procedure, etc. would fail if
hostapd enables OCV based on configuration but the driver doesn't
support OCV. To avoid this when driver SME is used, enable OCV from
hostapd only when the driver indicates support for OCV.

This commit also adds a capability flag to indicate whether driver SME
is used in AP mode.

d36d4209fd Enable beacon protection only when driver indicates support
Enabling beacon protection will cause STA connection/AP setup failures
if the driver doesn't support beacon protection. To avoid this, check
the driver capability before enabling beacon protection.

This commit also adds a capability flag to indicate beacon protection
support in client mode only.

b1c23d3f25 HE: Fall back to 20 MHz on 2.4 GHz if 40 MHz is not supported
At least the ACS case of an attempt to pick a 40 MHz channel on the 2.4
GHz band could fail if HE was enabled and the driver did not include
support for 40 MHz channel bandwidth on the 2.4 GHz band in HE
capabilities. This resulted in "40 MHz channel width is not supported in
2.4 GHz" message when trying to configure the channel and failure to
start the AP.

Avoid this by automatically falling back to using 20 MHz bandwidth as
part of channel parameter determination at the end of the ACS procedure.
