Patrick McHardy 5fd96123ee netlink: implement memory mapped sendmsg() ... Add support for mmap'ed sendmsg() to netlink. Since the kernel validates received messages before processing them, the code makes sure userspace can't modify the message contents after invoking sendmsg(). To do that only a single mapping of the TX ring is allowed to exist and the socket must not be shared. If either of these two conditions does not hold, it falls back to copying.
