From d0e8d6b9b566e9f0be64de0021b7c489e601a2fa Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Thu, 24 Oct 2019 04:08:16 +0200 Subject: fix OSMO_SOCKADDR_STR_FMT for IPv6 The format prints IP:port separated by a colon, which of course is confusing when the IPv6 address itself contains mostly colons. The new format adds square braces. cafe:face::1:42 -> [cafe:face::1]:42 The IPv4 format remains unchanged: 1.2.3.4:42 Change-Id: I161f8427729ae31be0eac719b7a4a9290715e37f --- include/osmocom/core/sockaddr_str.h | 8 ++++++-- tests/sockaddr_str/sockaddr_str_test.ok | 22 +++++++++++----------- 2 files changed, 17 insertions(+), 13 deletions(-) diff --git a/include/osmocom/core/sockaddr_str.h b/include/osmocom/core/sockaddr_str.h index d47b2a4e..6dd428c7 100644 --- a/include/osmocom/core/sockaddr_str.h +++ b/include/osmocom/core/sockaddr_str.h @@ -61,8 +61,12 @@ struct osmo_sockaddr_str { * struct osmo_sockaddr_str *my_sockaddr_str = ...; * printf("got " OSMO_SOCKADDR_STR_FMT "\n", OSMO_SOCKADDR_STR_FMT_ARGS(my_sockaddr_str)); */ -#define OSMO_SOCKADDR_STR_FMT "%s:%u" -#define OSMO_SOCKADDR_STR_FMT_ARGS(R) ((R)?
