[IPV6]: ipv6_fl_socklist is inadvertently shared.
The ipv6_fl_socklist from listening socket is inadvertently shared with new socket created for connection. This leads to a variety of interesting, but fatal, bugs. For example, removing one of the sockets may lead to the other socket's encountering a page fault when the now freed list is referenced. The fix is to not share the flow label list with the new socket. Signed-off-by: Masayuki Nakagawa <nakagawa.msy@ncos.nec.co.jp> Signed-off-by: David S. Miller <davem@davemloft.net>
