hostapd: update mesh DFS patches and add mesh HE support

Browse Source 
Drop outdated and by now broken patchset originally supplied by
Peter Oh in August 2018 but never merged upstream.
Instead add the more promissing rework recently submitted by
Markus Theil who picked up Peter's patchset, fixed and completed it
and added support for HE (802.11ax) in mesh mode.

This is only compile tested and needs some real-life testing.

Fixes: FS#3214
Fixes: 167028b750 ("hostapd: Update to version 2.9 (2019-08-08)")
Fixes: 0a3ec87a66 ("hostapd: update to latest Git hostap_2_9-1238-gdd2daf0848ed")
Fixes: 017320ead3 ("hostapd: bring back mesh patches")

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.

mode
This patch adds some missing pieces to the interface configuration
of AP/mesh mode in wpa_supplicant.
- check for secondary channel and HT40 capability
- try to downgrade to 11b if 11g is not available
Especially with the HT40 check, this code now performs all settings,
which the deleted/duplicated mesh code did.

Subject: [PATCH 6/7] mesh: don't allow pri/sec channel switch
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
until standard based implementation is introduced.

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 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.
