I found a couple of suspected bugs related to (source) address
handling while rummaging around the code...
When binding to a link-local address, inet6_bind() and raw6_bind() only
check that an interface is specified and that the address exists, but
they don't check if it actually exists on the specified interface.
Similarly, in datagram_sent_ctl() we don't check for the possibility of a
link-local address when we receive the source address from userspace.
The attached patch should fix this behavior.
