From ab11edcd4c2325e62ea0e02c80f7630b8d191300 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Mon, 16 Nov 2015 18:15:00 +0000 Subject: [PATCH] musl: fix handling of point-to-point interfaces in getifaddrs() Current musl reports the peer (remote) address of a point-to-point interface and does not store the local address at all. Apply the same special treatment of IFA_LOCAL to musl's getifaddrs() which is also used in glibc and uclibc.
