Subject: wait-online: handle varlink connection errors while waiting for DNS (#37283)
X-Git-Tag: v258-rc1~709
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=366dd4a662dac18c1a5beabb8f0c4c576a378206;p=thirdparty%2Fsystemd.git

wait-online: handle varlink connection errors while waiting for DNS (#37283)

Currently, if systemd-networkd-wait-online is started with --dns, and
systemd-resolved is not running, it will exit with an error right away.
Similarly, if systemd-resolved is restarted while waiting for DNS
configuration, systemd-networkd-wait-online will not attempt to
re-connect, and will potentially never see subsequent DNS
configurations.

Improve this by adding socket units for the systemd-resolved varlink
servers, and re-establish the connection in systemd-networkd-wait-online
when we receive `SD_VARLINK_ERROR_DISCONNECTED`.
