From: Sven Eckelmann <seckelmann@datto.com>

Some features of 802.11ax without central organizing (AP) STA can also be
used in mesh mode. hwsim can be used to assist initial development of these
features without having access to HW.

v6:

* rebased on top of 690c4509e980 ("mac80211_hwsim: Fix a typo in the name
   of function 'mac80211_hswim_he_capab()'")
* dropped incorrectly left "Forwarded" tag in commit message
* drop merged mac80211 patch
* drop ath11k patches will go to some special post-upstreaming branch and
  will be submitted separately

v5-v1:

* see https://lore.kernel.org/r/20190724163359.3507-1-sven@narfation.org

The patch was checked against hostapd's tests version 05822609d105
("HE: MCS size is always a minimum of 4 bytes") and the pending tshark < 3.1.0
workaround [1]. The latter is only affecting test "wpas_mesh_max_peering".

The other patch  [2] I had in my hostapd queue in earlier tests [3] was not
actually needed for hwsim+mesh.

I'm testing this now with a bit newer snapshot: 6a7ce95d752e
("staging/octeon: Fix build error without CONFIG_NETDEVICES").

And with the exact same snapshot of hostap.git.

Without [1] applied, this mac80211_hwsim patch to enable HE meshpoint
results in the following test cases failing:

mesh_secure_ocv_mix_legacy
wpas_mesh_open_ht40
wpas_mesh_max_peering
mesh_secure_ocv_mix_ht

[1] fixes wpas_mesh_max_peering

This leaves following three test cases failing ("Test exception:
Couldn't join mesh"):

mesh_secure_ocv_mix_legacy
wpas_mesh_open_ht40
mesh_secure_ocv_mix_ht

Am I missing a patch somewhere that would be needed to make those pass?


More specific reason for the failures:

wpas_mesh_open_ht40:

nl80211: mesh join (ifindex=3)
  * freq=5180
  * he_enabled=1
  * vht_enabled=0
  * ht_enabled=1
  * bandwidth=0
wlan0: mesh join error=-1

mesh_secure_ocv_mix_legacy:

same issues on dev1, but dev0 did complete join with a different set of
parameters:

nl80211: mesh join (ifindex=3)
  * freq=5200
  * he_enabled=1
  * vht_enabled=1
  * ht_enabled=1
  * bandwidth=80
  * channel_width=3
  * center_freq1=5210
  * center_freq2=0
  * Mesh ID (SSID)=wpas-mesh-sec
  * flags=0000000D
  * IEs - hexdump(len=22): 30 14 01 00 00 0f ac 04 01 00 00 0f ac 04 01 00 00 0f ac 08 c0 40
nl80211: mesh join request send successfully


(and same for mesh_secure_ocv_mix_ht)

So is that missing of vht_enabled=1 from some configurations the problem
here and if so, would you be able to point me to a hostap.git patch that
addresses this?

No, these also failed for me without the mac80211_hwsim patch [3] in a full 
test run. And thus not analyzed further by me.

Interestingly, they don't fail (without the hwsim patch) when running them
without the full test suite.

No, there is no hostap.git patch here. There was one in the past in 
patchwork [4] but there were concerns by John. So if you reapply the patch 
then you will see that it doesn't fail anymore.

    diff --git a/src/drivers/driver_nl80211.c b/src/drivers/driver_nl80211.c

So as a compromise, I can can propose a patch which tries to replicate this 
2.4GHz specific behavior from nl80211_put_freq_params also in 
ibss_mesh_setup_freq

Btw. thanks for pointing me towards specific test cases.

Kind regards,
	Sven
