[RTnet-users] rt_dev_ioctl causes kernel panic!

[Teresa Noviello]

Hi! I have wrote an RTT program, it's a little bit different from that in /examples/xenomai/posix, using rtnet and RTAI, in user space (LXRT module). It works fine but when i try to extend the socket pool of the sockets, i have no error messages but after the call the program causes kernel panic! The structure of the program is:

sock = rt_dev_socket(AF_INET, SOCK_DGRAM,0);
if (sock<0){
...
}

ret = ret_dev_ioctl(sock, RTNET_RTIOC_EXTPOOL, &add_rtskbs);

if(ret != add_rtskbs) {
 exit(1);
} else {
 printf("Buffer pool extended\n");
}

//...

//rt_task_init

//etc

You see that i create the socket before rt_task_init call, but all works fine without "rt_dev_ioct" call.
What can i do?
