Strict policy on FC6 and F7

Hi,
I'm still having problems compiling the local.te module. The problem i'm facing seems to be different from Hal's:
--------------------
local.te:11:ERROR 'permission nlsms_relay is not defined for class netlink_audit_socket' at token '
;' on line 80809:
allow local_login_t self:netlink_audit_socket { { create { ioctl read getattr write setattr
append bind connect getopt setopt shutdown } } nlmsg_read nlsms_relay };
#line 11
/usr/bin/checkmodule: error(s) encountered while parsing configuration
make: *** [tmp/local.mod] Error 1
---------------------
My local.te file looks like this:
-------------
policy_module(local,1.0)
require {
type local_login_t;
class netlink_audit_socket { append bind connect shutdown ioctl getattr setattr shutdown ge
topt setopt write nlmsg_relay nlmsg_read create read };
}
logging_send_audit_msg(local_login_t)
logging_set_loginuid(local_login_t)
-------------
Seems like the problem is with logging_set_loginuid macro. I'm not sure how to solve this problem though.
BTW here are some details on my environment:
1. I'm using the stock policy for FC7 2.6.4-8
2. I did the compilation while running in targeted mode (will it affect?)
3. The macro logging_set_loginuid is defined in the file policy-20070501.patch
Here is an extract of how logging_set_loginuid is defined in the patch :
+########################################
+## <summary>
+## Set login uid
+## </summary>
+## <param name="domain">
+## <summary>
+## Domain allowed access.
+## </summary>
+## </param>
+#
+interface(`logging_set_loginuid',`
+ gen_require(`
+ attribute can_set_loginuid;
+ attribute can_send_audit_msg;
+ ')
+
+ typeattribute $1 can_set_loginuid, can_send_audit_msg;
+
+ allow $1 self:capability audit_control;
+ allow $1 self:netlink_audit_socket { create_socket_perms nlmsg_read nlsms_relay };
+')
Hope it helps in solving the problem...
Thanks,
Louis

I think F7 strict policy is broken.
Let's wait for a while until SELinux guys fix it.
I decided to play with FC6 this time.
