commit 3e2f27e13b94f7302ad948bcacb5e02c859a25fc
Author: Daniel P. Berrange <berrange@redhat.com>
Date: Thu Oct 10 13:09:08 2013 +0100
Don't link virt-login-shell against libvirt.so (CVE-2013-4400)
The libvirt.so library has far too many library deps to allow
linking against it from setuid programs. Those libraries can
do stuff in __attribute__((constructor) functions which is
not setuid safe.
The virt-login-shell needs to link directly against individual
files that it uses, with all library deps turned off except
for libxml2 and libselinux.
Create a libvirt-setuid-rpc-client.la library which is linked
to by virt-login-shell. A config-post.h file allows this library
to disable all external deps except libselinux and libxml2.

Fix perms for virConnectDomainXML{To,From}Native (CVE-2013-4401)
The virConnectDomainXMLToNative API should require 'connect:write'
not 'connect:read', since it will trigger execution of the QEMU
binaries listed in the XML.
Also make virConnectDomainXMLFromNative API require a full
read-write connection and 'connect:write' permission. Although the
current impl doesn't trigger execution of QEMU, we should not
rely on that impl detail from an API permissioning POV.

Add helpers for getting env vars in a setuid environment
Care must be taken accessing env variables when running
setuid. Introduce a virGetEnvAllowSUID for env vars which
are safe to use in a setuid environment, and another
virGetEnvBlockSUID for vars which are not safe. Also add
a virIsSUID helper method for any other non-env var code
to use.
