Re: [Xen-devel] [XSM] Can't Build Policies
Oops, right you are on the colon, but it still doesn't work correctly
(even updated, cleaned, rebuilt) which I'm guessing is something to do
with a broken checkpolicy install if it works for you. I'll explore
that.
--------------------
[tom@Mavlo policy]$ /usr/bin/checkpolicy -d -c 20 policy.conf -o policy.20
/usr/bin/checkpolicy: loading policy configuration from policy.conf
tmp/only_te_rules.conf":55:ERROR 'syntax error' at token ':' on line 491:
################################################################################
allow dom0_t xen_t:xen {kexec readapic writeapic mtrr_read mtrr_add
mtrr_del scheduler physinfo heap quirk readconsole writeconsole
settime microcode};
checkpolicy: error(s) encountered while parsing configuration
--------------------
