Hi, There is a function move_addr_to_kernel() used by sys_bind() system call. You can see the definition of this function in net/socket.c file. This in fact used the call copy_from_user(). Hope this helps. Regards --gb Never trust an operating system you don't have sources for. ;-) On Thu, 1 Aug 2002, Jeremy Andrus wrote: > > Hello, > I have written a custom netfilter target that sends a small amount of > data out over the PCI bus.
