See lp#1276719 for the bug description. As virt-aa-helper doesn't know
the VFIO groups to use for the guest, allow access to all
/dev/vfio/[0-9]* and /dev/vfio/vfio files if there is a potential need
for vfio

use_apparmor() was first designed to be called from withing libvirtd,
but libvirt_lxc also uses it. in libvirt_lxc, there is no need to check
whether to use apparmor or not: just use it if possible.
The security driver expects /etc/apparmor.d/libvirt/TEMPLATE but we
installed it to /etc/apparmor.d/libvirtd/TEMPLATE. Move the template to
the expected place since that code was here long before.
Make it easy to install the shipped examples. The aim is to have
reasonably working templates so that distros only need to minimally
patch these and can feed things upstream more easily.
This was prompted by http://bugs.debian.org/725144
This patch provides AppArmor policy updates for the QEMU bridge helper.
The QEMU bridge helper is a SUID executable exec'd by QEMU that drops
capabilities to CAP_NET_ADMIN and adds a tap device to a network bridge.

I went with the shorter license notice used by src/libvirt.c,
rather than spelling out the full LGPLv2+ clause into each of
these files.
* configure.ac: Declare copyright.
* all Makefile.am: Likewise.
In the Ubuntu development release we recently got a new udev that
moves /var/run to /run, /var/lock to /run/lock and /dev/shm to /run/shm.
This change in udev requires updating the apparmor security driver in
libvirt[1].
Attached is a patch that:
* adjusts src/security/virt-aa-helper.c to allow both
LOCALSTATEDIR/run/libvirt/**/%s.pid and /run/libvirt/**/%s.pid. While
the profile is not as precise, LOCALSTATEDIR/run/ is typically a symlink
to /run/ anyway, so there is no additional access (remember that
apparmor resolves symlinks, which is why this is still required even
if /var/run points to /run).
* adjusts example/apparmor/libvirt-qemu paths for /dev/shm

tests/virt-aa-helper-test and examples/apparmor are not included in
official tarballs, but should be. Attached is a patch to fix that
which works when apparmor is and is not available.
* examples/apparmor/libvirt-qemu: adds pulseaudio, alsa and preliminary
save/restore to the example apparmor abstraction
* examples/apparmor/usr.sbin.libvirtd: allows libvirtd access to inet
dgram, inet6 dgram, inet6 stream and /usr/lib/libvirt/*
* docs/drvqemu.html.in: include documentation for AppArmor sVirt
confinement
* examples/apparmor/TEMPLATE examples/apparmor/libvirt-qemu

examples/apparmor/usr.sbin.libvirtd: example templates and
configuration files for SVirt Apparmor when using KVM/QEmu
