I'm testing this now with a bit newer snapshot: 6a7ce95d752e

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?
