I'm attempting to change the behaviour of the inet_get_local_port_range function in the kernel, I've created a kprobe that sets regs->ip = (unsigned long)&inet_get_local_port_range_handler_fake in the pre_handler, and returns 1. I've specified a post_handler to avoid kprobe optimization. Unfortunately, I get a fault immediately after this. I saw in an earlier mailing list post (http://lkml.iu.edu/hypermail/linux/kernel/1310.2/02545.html) suggesting to call reset_current_kprobe(), and preempt_enable_no_resched(). Unfortunately these are not exported to my module. Is there any other way to detour the kernel execution path? _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
