From 6bd8283bf962126da73612737a5730082b70b5f3 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 17 Jul 2024 10:36:03 +1000 Subject: util: Add AF_UNSPEC support to sockaddr_ntop() Allow sockaddr_ntop() to format AF_UNSPEC socket addresses. There do exist a few cases where we might legitimately have either an AF_UNSPEC or a real address, such as the origin address from MSG_ERRQUEUE. Even in cases where we shouldn't get an AF_UNSPEC address, formatting it is likely to make things easier to debug if we ever somehow do.
