+Subject: [PATCH 01/19] HE/VHT: fix frequency setup with HE enabled
+
+Some places in the code base were not using the
+wrappers like hostapd_set_oper_centr_freq_seg0_idx
+and friends. This could lead to errors, for example when
+joining 80 MHz mesh networks. Fix this, by enforcing
+usage of these wrappers.
+
+wpa_supplicant_conf_ap_ht now checks for HE capability
+before dealing with VHT in order for these wrappers to work,
+as they first check HE support in the config.
+
+While doing these changes, I've noticed that the extra
+channel setup code for mesh networks in wpa_supplicant/mesh.c
+should not be necessary anymore and dropped it.
+wpa_supplicant_conf_ap_ht should handle this setup already.

+Subject: [PATCH 02/19] mesh: fix channel init order, disable pri/sec channel
+ switch
+
+wpa_supplicant_conf_ap_ht has to happen before hostapd_setup_interface
+in order for its configuration settings to have effect on interface
+configuration.
+
+Disable primary and secondary channel switch because of missing tie
+breaking rule/frames in mesh networks. A rather long comment about
+this issue is placed in mesh.c in the corresponding place.
+
+In consequence, remove mesh coex test, which contradicts this change.
+
+I was not able to reproduce the memory corruption during
+mesh_secure_ocv_mix_legacy, which lead to a revert of a similar patch
+in the past.

-
-mesh join function is the last function to be called during
-mesh join process, but it's been called a bit earlier than
-it's supposed to be, so that some mesh parameter values
-such as VHT capabilities not applied correct when mesh join
-is in process.
-Moreover current design of mesh join that is called directly
-after mesh initialization isn't suitable for DFS channels to use,
-since mesh join process should be paused until DFS CAC is
-done and resumed after it's done.
-The callback will be called by hostapd_setup_interface_complete_sync.
-There is possiblity that completing mesh init fails, so add error
-handle codes.

+Subject: [PATCH 08/19] mesh: use setup completion callback to complete mesh
+ join
+
+mesh join function is the last function to be called during
+mesh join process, but it's been called a bit earlier than
+it's supposed to be, so that some mesh parameter values
+such as VHT capabilities not applied correct when mesh join
+is in process.
+Moreover current design of mesh join that is called directly
+after mesh initialization isn't suitable for DFS channels to use,
+since mesh join process should be paused until DFS CAC is
+done and resumed after it's done.
+The callback will be called by hostapd_setup_interface_complete_sync.
+There is possiblity that completing mesh init fails, so add error
+handle codes.

+Mesh interface has used its channel parameters that configured

-
-This limitation isn't backed by standard, but it is known that
-mesh doesn't have capability to handle 20/40 coex change in
-current implementation and it will not able to establish
-PLINK when channel switch between primary and secondary happens.
-
-Since it's unknown when we will have the implementation of handling
-20/40 coex change for mesh, it'd better to avoid them from happening

+Subject: [PATCH 15/19] mesh: fix DFS deinit/init
+
+The hostapd DFS code deinitializes and initializes the
+AP interface, if a clean channel switch is not possible.
+In this case the AP code paths would deinit the driver, for
+example nl80211, without wpa_supplicant code paths getting
+notice of this.
+
+Therefore add callbacks for wpa_supplicant mesh methods,
+which are called on init/deinit of the AP bss. These
+callbacks are then used to handle the reset in the mesh
+code.

-Subject: [PATCH 5/7] mesh: fix channel switch error during CAC
-
-Mesh interface has used its channel parameters that configured
-during its initialization even after channel switched due to
-DFS radar detection during CAC which caused channel switch error.
-This change fixes the error by updating its channel parameters
-when channel's been changed from initial one.

+Subject: [PATCH 19/19] mesh: use deterministic channel on channel switch
+
+This patch uses a deterministic channel on DFS channel switch
+in mesh networks. Otherwise, when switching to a usable but not
+available channel, no CSA can be sent and a random channel is choosen
+without notification of other nodes. It is then quite likely, that
+the mesh network gets disconnected.
+
+Fix this by using a deterministic number, based on the sha256 hash
+of the mesh ID, in order to use at least a different number in each
+mesh network.
