From 44cf6731d6b9a48bcd57392e8cd6f0f712aaa677 Mon Sep 17 00:00:00 2001 From: Mathis Marion Date: Tue, 7 Mar 2023 16:42:55 +0100 Subject: [PATCH] linux-user: fix sockaddr_in6 endianness MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The sin6_scope_id field uses the host byte order, so there is a conversion to be made when host and target endianness differ.
