Re: [libvirt] [TCK] nwfilter tests and libvirt commit 4f209434

Hi, As I've been looking through libvirt-tck tests, I found that commit 4f209434 (in libvirt) changes a condition that the nwfilter/050-apply-verify-host.t relies on. Specifically, the 050-apply-verify-host.t test creates a number of filters with invalid values (such as dscp='64', and protocol='256'). Without commit 4f209434, these invalid values are silently dropped off the end of the rule, as in the following example: #virsh nwfilter-define <xml with illegal value:> <filter name='tck-testcase'> <uuid>5c6d49af-b071-6127-b4ec-6f8ed4b55335</uuid> <rule action='accept' direction='in'> <ip srcipaddr='10.1.2.3' srcipmask='255.255.255.254' dstipaddr='10.1.2.3' dstipmask='255.255.255.128' protocol='255' dscp='64' /> </rule> #virsh nwfilter-dumpxml tck-testcase <rule action='accept' direction='in' priority='500'> <ip srcipaddr='10.1.2.3' srcipmask='31' dstipaddr='10.1.2.3' dstipmask='25' protocol='255'/> </rule> With commit 4f209434 in place, the entire filter is rejected with the following error: 'internal error: dscp has illegal value 64'. As the filter is not created, the testing of that filter by the 050-apply-verify-host test fails. I agree that the change is the right thing to do, but I'm wondering how best to handle the now failing tests. This test (050-apply-verify-host.t) runs ~1200 subtests, and about 10% of those tests fail due to the change. I'm thinking that the illegal options (and only those illegal options) should be removed from the now broken tests, and a few new tests added to specifically test for the failure to add the entire rule when illegal data is passed. Thoughts?
