Not trying to discourage you, but I assume your "filtering" function will be engaged many many times in the case of rapid traffic...thus, the buffer might grow rapidly too, right? In that case, are you sure direct mapping could cope with it? Well unless you're ready to loose some data ..... Anyway, I think you can do that by reserve the buffer in user space and the get_user_page() them. As the bridge, a unique device with ioctl() might do the job. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
