From 801ad6a6a9cd8fbd58b9f9c27f20dbb3c87d47dd Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Wed, 25 Nov 2015 20:47:27 +0100 Subject: resolved: fully support DNS search domains This adds support for searching single-label hostnames in a set of configured search domains. A new object DnsQueryCandidate is added that links queries to scopes. It keeps track of the search domain last used for a query on a specific link. Whenever a host name was unsuccessfuly resolved on a scope all its transactions are flushed out and replaced by a new set, with the next search domain appended. This also adds a new flag SD_RESOLVED_NO_SEARCH to disable search domain behaviour. The "systemd-resolve-host" tool is updated to make this configurable via --search=.
