From 3b5eaad3c8b49367d1812dbaf4182fc7282b7f00 Mon Sep 17 00:00:00 2001 From: Ian Gudger Date: Fri, 12 Jun 2020 20:47:28 -0700 Subject: Allow reading IP_MULTICAST_LOOP and IP_MULTICAST_TTL on TCP sockets. I am not really sure what the point of this is, but someone filed a bug about it, so I assume something relies on it.
