From eae303ff23f51259eddc8856c71453d887ffe51a Mon Sep 17 00:00:00 2001 From: Guillaume Subiron Date: Sat, 19 Dec 2015 22:24:58 +0100 Subject: slirp: Make Socket structure IPv6 compatible This patch replaces foreign and local address/port couples in Socket structure by 2 sockaddr_storage which can be casted in sockaddr_in. Direct access to address and port is still possible thanks to some \#define, so retrocompatibility of the existing code is assured. The ss_family field of sockaddr_storage is declared after each socket creation. The whole structure is also saved/restored when a Qemu session is saved/restored. This prepares for IPv6 support.
