From 2e97e980b5653c23d01c911af6a0ab2d3431d7f1 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 26 Apr 2011 13:57:47 -0700 Subject: [PATCH] ipv4: Remove erroneous check in igmpv3_newpack() and igmp_send_report(). Output route resolution never returns a route with rt_src set to zero (which is INADDR_ANY). Even if the flow key for the output route lookup specifies INADDR_ANY for the source address, the output route resolution chooses a real source address to use in the final route. This test has existed forever in igmp_send_report() and David Stevens simply copied over the erroneous test when implementing support for IGMPv3. Signed-off-by: David S.
