From 1cb1c5d10bb9e180bd3f7be2c10b212ed86a97b4 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Thu, 5 Jul 2012 19:35:57 +0200 Subject: [PATCH] slirp: Enforce host-side user of smb share Windows 7 (and possibly other versions) cannot connect to the samba share if the exported host directory is not world-readable. This can be resolved by forcing the username used for access checks to the one under which QEMU and smbd are running.
