-- Check that an NS in an authority section returned from a forwarder - which is above the name in a configured "forward first" or "forward - only" zone (i.e., net/NS in a response from a forwarder configured for - local.net) is not cached. -- Test that a DNAME for a parent domain will not be cached when sent - in a response from a forwarder configured to answer for a child. -- Check that glue is rejected if its name falls below that of zone - configured locally. -- Check that an extra out-of-bailiwick data in the answer section is - not cached (this was already working correctly, but was not explicitly - tested before). - -- v9_11 backport: Revert primary/secondary to master/slave, - backport rndc helper, backport ns8 config. - -(cherry picked from commit bf3fffff67e1de78e9387a93674d471bf4291604) -(cherry picked from commit 29f08170f05c2c96fb67f3b561b46aa0bae356f7) ---- - bin/tests/system/forward/ans11/ans.py | 136 ++++++++++++++++++ -

To be safe, we don't cache any responses if the -forwarding configuration has changed since the query was sent. - -(cherry picked from commit 590f8698fc876d6d72f75cf35359e7546c3af972) - -Check cached names for possible "forward only" clause - -When caching additional and glue data *not* from a forwarder, we must -check that there is no "forward only" clause covering the owner name -that would take precedence. Such names would normally be allowed by -baliwick rules, but a "forward only" zone introduces a new baliwick -scope. - -(cherry picked from commit 4a144fae16e70517be894a971cef1d085ee68ebe) - -Look for zones deeper than the current domain or forward name - -When caching glue, we need to ensure that there is no closer -source of truth for the name. If the owner name for the glue -record would be answered by a locally configured zone, do not -cache. - -(cherry picked from commit 42f8c538d3fb9d075b98d82688aeb71621798754) - -Avoid use of compound literals - -Compound literals are not used in BIND 9.11, in order to ensure backward -compatibility with ancient compilers. Rework the relevant parts of the -BIND 9.11 backport of the CVE-2021-25220 fix so that compound literals -are not used. - -(cherry picked from commit d4b1efbcbd4dfb8c6ef303968992440c5bdeed15) ---- - lib/dns/resolver.c | 130 +++++++++++++++++++++++++++++++++++++++++++-- - 1 file changed, 125 insertions(+), 5 deletions(-) - -diff --git a/lib/dns/resolver.c b/lib/dns/resolver.c -index c912f3aea8..2c68973899 100644 ---- a/lib/dns/resolver.c -+++ b/lib/dns/resolver.c -@@ -63,6 +63,7 @@ - #include - #include - #include -+#include - - #ifdef WANT_QUERYTRACE - #define RTRACE(m) isc_log_write(dns_lctx, \ -@@ -312,6 +313,8 @@ struct fetchctx { - bool ns_ttl_ok; - uint32_t ns_ttl; - isc_counter_t * qc; -+ dns_fixedname_t fwdfname; -+ dns_name_t *fwdname; - - /*% - * The number of events we're waiting for. -@@ -3393,6 +3396,7 @@ fctx_getaddresses(fetchctx_t *fctx, bool badcache) { - if (result == ISC_R_SUCCESS) { - fwd = ISC_LIST_HEAD(forwarders->fwdrs); - fctx->fwdpolicy = forwarders->fwdpolicy; -+ dns_name_copy(domain, fctx->fwdname, NULL); - if (fctx->fwdpolicy == dns_fwdpolicy_only && - isstrictsubdomain(domain, &fctx->domain)) { - fcount_decr(fctx); -@@ -4422,6 +4426,9 @@ fctx_create(dns_resolver_t *res, dns_name_t *name, dns_rdatatype_t type, - fctx->restarts = 0; - fctx->querysent = 0; - fctx->referrals = 0; -+ -+ fctx->fwdname = dns_fixedname_initname(&fctx->fwdfname); -+ - TIME_NOW(&fctx->start); - fctx->timeouts = 0; - fctx->lamecount = 0; -@@ -4480,8 +4487,10 @@ fctx_create(dns_resolver_t *res, dns_name_t *name, dns_rdatatype_t type, - domain = dns_fixedname_initname(&fixed); - result = dns_fwdtable_find2(fctx->res->view->fwdtable, fwdname, - domain, &forwarders); -- if (result == ISC_R_SUCCESS) -+ if (result == ISC_R_SUCCESS) { - fctx->fwdpolicy = forwarders->fwdpolicy; -+ dns_name_copy(domain, fctx->fwdname, NULL); -+ } - - if (fctx->fwdpolicy != dns_fwdpolicy_only) { - /* -@@ -6231,6 +6240,112 @@ mark_related(dns_name_t *name, dns_rdataset_t *rdataset, - rdataset->attributes |= DNS_RDATASETATTR_EXTERNAL; - } - -+/* -+ * Returns true if 'name' is external to the namespace for which -+ * the server being queried can answer, either because it's not a -+ * subdomain or because it's below a forward declaration or a -+ * locally served zone. -+ */ -+static inline bool -+name_external(dns_name_t *name, dns_rdatatype_t type, fetchctx_t *fctx) { -+ isc_result_t result; -+ dns_forwarders_t *forwarders = NULL; -+ dns_fixedname_t fixed, zfixed; -+ dns_name_t *fname = dns_fixedname_initname(&fixed); -+ dns_name_t *zfname = dns_fixedname_initname(&zfixed); -+ dns_name_t *apex = NULL; -+ dns_name_t suffix; -+ dns_zone_t *zone = NULL; -+ unsigned int labels; -+ dns_namereln_t rel; -+ /* -+ * The following two variables do not influence code flow; they are -+ * only necessary for calling dns_name_fullcompare(). -+ */ -+ int _orderp = 0; -+ unsigned int _nlabelsp = 0; -+ -+ apex = ISFORWARDER(fctx->addrinfo) ?
