From a51c10485af349eb15faa4d1a63b9818bcf3e589 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Tue, 24 Nov 2015 21:12:51 +0100 Subject: resolved: add a generic DnsSearchDomain concept With this change, we add a new object to resolved, "DnsSearchDomain=" which wraps a search domain. This is then used to introduce a global search domain list, in addition to the existing per-link search domain list which is reword to make use of this new object too. This is preparation for implement proper unicast DNS search domain support. --- src/resolve/resolved-dns-search-domain.h | 71 ++++++++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 src/resolve/resolved-dns-search-domain.h (limited to 'src/resolve/resolved-dns-search-domain.h') diff --git a/src/resolve/resolved-dns-search-domain.h b/src/resolve/resolved-dns-search-domain.h new file mode 100644 index 0000000000..20b441206c --- /dev/null +++ b/src/resolve/resolved-dns-search-domain.h @@ -0,0 +1,71 @@ +/*-*- Mode: C; c-basic-offset: 8; indent-tabs-mode: nil -*-*/ + +#pragma once + +/*** + This file is part of systemd. + + Copyright 2015 Lennart Poettering + + systemd is free software; you can redistribute it and/or modify it + under the terms of the GNU Lesser General Public License as published by + the Free Software Foundation; either version 2.1 of the License, or + (at your option) any later version. + + systemd is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
