net/unix: don't show information about sockets from other namespaces
socket_diag shows information only about sockets from a namespace where a diag socket lives. But if we request information about one unix socket, the kernel don't check that its netns is matched with a diag socket namespace, so any user can get information about any unix socket in a system. This looks like a bug. v2: add a Fixes tag Fixes: 51d7cccf0723 ("net: make sock diag per-namespace") Signed-off-by: Andrei Vagin <avagin@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
