Description Tom London 2008-02-20 14:37:13 EST
Description of problem:
Running selinux-policy-targeted-3.2.8-2.fc9.noarch targeted/permissive, I get
the following running a WinXP image (AVCs attached):

#============= qemu_t ==============
allow qemu_t http_port_t:tcp_socket name_connect;
allow qemu_t inaddr_any_node_t:udp_socket node_bind;
allow qemu_t kerberos_port_t:tcp_socket name_connect;
allow qemu_t ldap_port_t:tcp_socket name_connect;
allow qemu_t port_t:tcp_socket name_connect;
allow qemu_t reserved_port_t:tcp_socket name_connect;
allow qemu_t self:udp_socket { write bind create read getattr };
allow qemu_t smbd_port_t:tcp_socket name_connect;

I suspect there will be more, as I "exercise" the WinXP guest.

What I did: ran "qemu-kvm -m 400 image", logged in to windows domain, started
outlook, started browser (IE, sigh).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.  Start guest: qemu-kvm -m 400 image
2.  login to domain
3.  start Outlook, start browser
Actual results:

Expected results:

So I guess we need a boolean that says we are allowed to connect to anyport. 
This is interesting though.  Since we can begin to confine WinXP with
qemu/selinux.  If I want to write the policy equivalent of xguest for XP, I
would write a policy that runs qemu in a domain that is only allowed to connect
to the http ports/dns/ftp ports.

SELinux confining Windows...

What kind of networking did you setup to get this?
Comment 4 Tom London 2008-02-20 16:45:53 EST
We'll have to call it SEWindows..... Wonder if they've already locked in a
trademark for that .... ;)
Comment 5 Tom London 2008-02-20 16:53:23 EST
Network setup..... I believe I'm using whatever is the default.

The XP guest thinks it is connected to

The host is running on

I don't think I've ever specified any "-net" options..... Thinks the device is a
RealTek rtl8139.

I presume it is NAT-ing, but not sure.
