Hello qemu developers, This patch is from android emulator (which is based on qemu2.2) and I hope this patch is also useful to upstream qemu as well. bo From 021eac8c593a34a6a5e106d187a8e1fd22a1522f Mon Sep 17 00:00:00 2001 From: bohu <bohu@google.com> Date: Wed, 2 Nov 2016 15:56:26 -0700 Subject: [PATCH] slirp: fix ipv6 guest network access with windows host In tcp_input function, local sockaddr_storage variables lhost and fhost are used without being cleared to zero; and consequently tcp connect call fails on windows because there is some random data in those variables (windows complains with WSAEADDRNOTAVAIL); This CL calls memset to clear those two variables so that the address passed to connect does not have random data in it.
