From 56c7eb3b504ae4345c765a4f919d1be8192446c3 Mon Sep 17 00:00:00 2001 From: Roman Safronov Date: Mon, 25 Dec 2023 16:55:27 +0200 Subject: [PATCH] Add workaround for DHCP opts test and minor fixes This patch contains a workaround for one of extra dhcp opts test, test_extra_dhcp_opts_disabled_enabled_dhcp4, that uses a strict regex for getting domain_name between 'search' and eand of the line. In some cases the test is failing because of an extra entry 'n' before the end of the line. This still should be investigated. Meanwhile we apply a workaround in order to unblock the gates. The workaround makes the regex less strict and still checks for a proper value of the domain_name. This patch also handles 2 comments from the previous patch.
