*sax = (struct sockaddr_ax25 *)msg->msg_name;
Here, - *sax - seems to point to users `msg_name' object, no? Because of
the earlier copy_from_user in net/socket.h:
===
get_compat_msghdr(msg_sys, msg_compat)
OR
copy_from_user(msg_sys, msg, sizeof(struct msghdr)
===
Is - memset(sax, 0, sizeof(full_sockaddr_ax25)) - setting users memory area?
Thank you.
