Hi, Marco
I have tried to use this patch in open mesh, no problem.
But if testing with secured mesh (authsae), it causes the following
kernel panic.
Appreciate if you can take a look on this. Thanks
Regards,
Chun-Yeow

Hi,
thanks for reporting this; I can confirm that bug.
It is triggered by
BUG_ON(!timer->function);
in timer.c after calling mod_timer in mesh_peer_init.
Ok, so I have to dig into, what is different in peering when userspace
tools are involved.
Regards,
Marco
