bindresvport() uses two static variables port and startport which are not
protected. It is not safe when in multithread circumstance. bindresvport() select a port number from the range 512 to 1023, when in multithread circumstance, the port may be 1024. So the static variables will be protected. Signed-off-by: Peng Haitao <penght@cn.fujitsu.com> Reviewed-by: Carlos O'Donell <carlos@systemhalted.org>
