previously, rpz_rrset_find() behaved differently depending on whether a cache lookup returned DNS_R_DELEGATION or ISC_R_NOTFOUND. the former indicates the presence of a cached NS rrset, and the latter indicates that the cache is cold or that all NS rrsets above the query name have expired. both results indicate that the caller should recurse, but rpz_rrset_find() only recursed in the case of DNS_R_DELEGATION. the nsip-wait-recurse and nsdname-wait-recurse test cases in the rpzrecurse system test were dependent on this misbehavior. the test server was configured with a lame delegation, so that recursion always failed, but once the lame delegation was expired due to a zero TTL, the cache returned ISC_R_NOTFOUND, which caused the recursion not to be attempted. the test seemed to be observing a delay before recursion succeeded, but it was actually observing a delay before recursion was skipped. fixing this bug caused the test to fail. the test server has now been reconfigured so that recursion succeeds after a delay, instead of failing. now we're able to test that we're waiting for the successful completion of recursion. |
