I'm developing a kernel module that will be doing inspection and
needed access to raw network frames,
But the module will never unload: ( but the UNLOAD and QUIESE event
handlers are invoked)
> #make unload :ro:~/tmp/
> food.ko:3:14:28:31
> /sbin/kldunload -vf food.ko
> Unloading food.ko, id=7
> kldunload: can't unload file: Device busy
> *** Error code 1
>
> Stop in /root/tmp/food.ko.
> Exit 1
> #Mar 18 03:14:31 kernel: quiesced :ro:~/tmp/
> food.ko:3:14:31:32
> Mar 18 03:14:31 kernel: foodmod unloaded
Thanks so much for looking at it Julian, I never could get my
netgraph module to unload, out of frustration I replaced the
interfaces if_input routine with my own. I don't share this interface
with the host's stack, so this measure seems appropriate.
Now I have to grab about 10Gb of ram for a data structure.. I hope
that's just tuning.
