Hi All,

I wrote a module that puts a netfitler hook on receiving IP packets (NF_IP_PRE_ROUTING).
I want to debug it using UML, but strangely, the skbuf I get in the hook is always NULL.

This looks strange to me as the module has worked in real linux pretty well.

I use linux version for the UML.

Is there some option I need to turn on in the configuration?
