* [PATCH] selinux-testsuite:  Allow test domains to read /etc/passwd

Several test cases require the ability to read /etc/passwd to look
up usernames.  Recent Fedora introduced a separate type on /etc/passwd
and therefore we need to add an interface call to test_global.te.  Fixes
three test failures on Fedora 17.

Probably should use

auth_use_nsswitch(testdomain)

Since this will handle cases where users are listed in ldap or use sssd.

Also please try to not depend on distribution policies but rather
refpolicy. Other distributions don't use a separate type for passwd (yet?)
and I don't know if the interface suggested before is also supported.

No, it doesn't work - you cannot pass an attribute name to that
interface.

Ahh yes, you can not assign an attribute to an attribute.  That is right up
there with no assigning an attribute within a boolean as my least liked things
about our policy compiler.


I guess you need to add auth_use_nsswitch() for each type that gets set to
test_domain.

That would be rather painful.  For now, let's just use
auth_read_passwd(testdomain).  Works for me.

auth_use_nsswitch() might have undesirable side effects, like allowing
every test domain network access.  Which would then prevent testing
enforcement of the socket permission checks.

Can we please get auth_read_passwd defined in refpolicy then? If anything,
have it grant read access to etc_t. Otherwise tests in other distributions
but fedora will fail.

Wrap Fedora-specific policy with an ifdef.  Alternative would be to fork
a copy of the test policy per distro under policy/<distro>/<release> as
we have already done for redhat 4 and 5.
But I'd prefer to only do that for long-term stable/enterprise releases
that won't be changing very often.
