Tom Herbert 0643ee4fd1 inet: Fix get port to handle zero port number with soreuseport set ... A user may call listen with binding an explicit port with the intent that the kernel will assign an available port to the socket. In this case inet_csk_get_port does a port scan. For such sockets, the user may also set soreuseport with the intent a creating more sockets for the port that is selected. The problem is that the initial socket being opened could inadvertently choose an existing and unreleated port number that was already created with soreuseport. This patch adds a boolean parameter to inet_bind_conflict that indicates rather soreuseport is allowed for the check (in addition to sk->sk_reuseport). In calls to inet_bind_conflict from inet_csk_get_port the argument is set to true if an explicit port is being looked up (snum argument is nonzero), and is false if port scan is done.
