From d4e209d35564eecdc006ab9f5b10bc8494c6f1f9 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Fri, 7 Feb 2020 18:48:04 +0100 Subject: resolv: Fix CNAME chaining in resolv/tst-resolv-ai_idn-common.c The second CNAME record optionally generated by the response function used the question name, not the redirected name from the first CNAME. This breaks the chain and results in failures of these IDNA tests if CNAME owner names are checked as expected (which the current implementation does not do). --- resolv/tst-resolv-ai_idn-common.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/resolv/tst-resolv-ai_idn-common.c b/resolv/tst-resolv-ai_idn-common.c index 9e8ed76..97eb617 100644 --- a/resolv/tst-resolv-ai_idn-common.c +++ b/resolv/tst-resolv-ai_idn-common.c @@ -219,8 +219,9 @@ response (const struct resolv_response_context *ctx, } if (with_idn_cname) { + const char *previous_name = next_name; next_name = ANDERES_NAEMCHEN_IDNA ".example"; - resolv_response_open_record (b, qname, C_IN, T_CNAME, 0); + resolv_response_open_record (b, previous_name, C_IN, T_CNAME, 0); resolv_response_add_name (b, next_name); resolv_response_close_record (b); } -- cgit v1.1
