Subject: [Qemu-devel] [PATCH 0/5] linux-user: fake some /proc/self entries
Date: Wed, 2 Nov 2011 20:23:21 +0100 [thread overview]
Message-ID: <1320261806-13194-1-git-send-email-agraf@suse.de> (raw)
When running linux-user programs in QEMU, the guest program can examine
itself by checking /proc/self/ files. And some libraries really do use
this!
Unfortunately, when checking /proc/self/ today, the guest program sees
the QEMU files, exposing wrong information to the guest program.
This patch set fakes auxv, maps and stat to make gtk, pthread and boehm
gc happy.
