From 48a995da601f0b9037c652ca48337b4bf3f58d41 Mon Sep 17 00:00:00 2001 From: Brad House Date: Wed, 15 Nov 2023 09:33:47 -0500 Subject: [PATCH] test: dns test case failures after c-ares update to 1.21.0+ c-ares has made intentional changes to the behavior of TXT records to comply with RFC 7208, which concatenates multiple strings for the same TXT record into a single string. Multiple TXT records are not concatenated. Also, response handling has changed, such that a response which is completely invalid in formatting is thrown away as a malicious forged/spoofed packet rather than returning EBADRESP. This is one step toward RFC 9018 (EDNS COOKIES) which will require the message to at least be structurally valid to validate against spoofed records.
