15251c6584 hostapd: Fix dynamic ACCEPT_ACL management over control interface
hostapd_disassoc_accept_mac() was called after a new accept MAC address
was added (ACCEPT_ACL ADD_MAC), but this function should have been
called after an accept MAC address was removed and accept MAC list was
cleared to disconnect a STA which is not listed in the update accept MAC
address list. Fix this by moving the call to places where a connected
STA can actually end up losing its previously present accept entry.

0f8994b11d tests: Extend Multi AP tests
Add option to:
 - add a new AP on the same phy that the backhaul-sta uses
 - run CSA from the parent

Adding a new AP (backhaul/fronthaul) on the same phy we have for
backhaul-sta is closer to the real repeater implementation.

Add a test case for that and run CSA.

This is a common problem when we have on the same phy:
 - connected backhaul STA
 - we started fronthaul/backhaul AP
 - we receive (from parent) CSA on the STA interface

This is multi_ap_wps_shared_apdev_csa test case, which fails today with
both mac80211_hwsim and ath9k. To avoid always failing test cases,
ignore this failure for now. Full validation can be enabled once the
issue behind this is fixed.

Since a running hostapd is not necessarily using the settings that are
in the configuration file (if they were changed at runtime, or the file
was changed but not reloaded, etc.), being able to get their value at

3a00a86bb9 hostapd: Fix dpp_listen in DPP responder scenario
Some time ago it was found some drivers are setting their hw/ucode RX
filters restrictively enough to prevent broadcast DPP Action frames from
being received at upper layers in the stack.

A set of patches was introduced to the kernel and
ath9k driver as well as wpa_supplicant, e.g.,

  a39e9af90 ("nl80211: DPP listen mode callback")
  4d2ec436e ("DPP: Add driver operation for enabling/disabling listen mode")

However, the hostapd code itself was not calling the new multicast
registration. As such the AP side of things wasn't working as expected
in some scenarios. I've found this while trying to get ath9k working as
an AP Responder/Configurator.

The problem wasn't seen on, e.g., mac80211 hwsim driver.

Extend the wpa_supplicant mechanism to work with hostapd as well.

4a7e0ac268 hostapd: Add an option to notify management frames on ctrl_iface
In some contexts (e.g., Multi-AP) it can be useful to have access to
some of the management frames in upper layers (e.g., to be able to

Add 'notify_mgmt_frames'. When enabled, it will notify the ctrl_iface
when a management frame arrives using the AP-MGMT-FRAME-RECEIVED event
message.

Note that to avoid completely flooding the ctrl_iface, not all
management frames are included (e.g., Beacon and Probe Request frames
are excluded).

Add option 2 to the p2p_device_random_mac_addr configuration option to
support device drivers which use by default random MAC adresses when
creating a new P2P Device interface (for instance, the BCM2711 80211
wireless device driver included in Raspberry Pi 4 Model B). In such
case, this option allows to create the P2P Device interface correctly
when using P2P permanent groups, enabling wpa_supplicant to reuse the
same MAC address when re-invoking a P2P permanent group.

update_config=1 is required.

test data that would not be possible in real use cases due to MMPDU size
limits. The implementation for storing vendor IEs with such
unrealisticly long IE buffers can result in huge number of memory

11355a122d Reset external_scan_running on interface deletion
Currently, the external_scan_running flag is not reset when an interface
is removed. Thus, if a connection attempt is made on another iface, it
will fail due to wpa_supplicant incorrectly assuming the radio is still

To fix this, convert external_scan_running to a pointer to the interface
that started the scan. If this interface is removed, also reset the
pointer to NULL so that other operations may continue on this radio.

  2. Remove wlan0
