From 69ab640b6b8e74cb3de3e8f1ba43e34b75e644c5 Mon Sep 17 00:00:00 2001 From: trociny Date: Fri, 12 Jul 2013 19:08:33 +0000 Subject: A complete duplication of binding should be allowed if on both new and duplicated sockets a multicast address is bound and either SO_REUSEPORT or SO_REUSEADDR is set. But actually it works for the following combinations: * SO_REUSEPORT is set for the fist socket and SO_REUSEPORT for the new; * SO_REUSEADDR is set for the fist socket and SO_REUSEADDR for the new; * SO_REUSEPORT is set for the fist socket and SO_REUSEADDR for the new; and fails for this: * SO_REUSEADDR is set for the fist socket and SO_REUSEPORT for the new. Fix the last case.
