Re: [libvirt] [PATCH v2] apparmor: QEMU bridge helper policy updates

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. For more details on the helper, please refer to: http://lists.gnu.org/archive/html/qemu-devel/2012-01/msg03562.html Signed-off-by: Corey Bryant <coreyb(a)linux.vnet.ibm.com&gt; --- examples/apparmor/libvirt-qemu | 22 +++++++++++++++++++++- 1 files changed, 21 insertions(+), 1 deletions(-) diff --git a/examples/apparmor/libvirt-qemu b/examples/apparmor/libvirt-qemu index 10cdd36..c5a11b6 100644 --- a/examples/apparmor/libvirt-qemu +++ b/examples/apparmor/libvirt-qemu @@ -1,4 +1,4 @@ -# Last Modified: Mon Apr 5 15:11:27 2010 +# Last Modified: Fri Mar 9 14:43:22 2012 #include <abstractions/base> #include <abstractions/consoles> @@ -108,3 +108,23 @@ /bin/dash rmix, /bin/dd rmix, /bin/cat rmix, + + /usr/libexec/qemu-bridge-helper Cx, + + # child profile for bridge helper process + profile /usr/libexec/qemu-bridge-helper { + #include <abstractions/base> + + capability setuid, + capability setgid, + capability setpcap, + capability net_admin, + + network inet stream, + + /dev/net/tun rw, + /etc/qemu/** r, + owner @{PROC}/*/status r, + + /usr/libexec/qemu-bridge-helper rmix, + }
