resolved: add daemon to manage resolv.conf Also remove the equivalent functionality from networkd.

units: fix typo in systemd-resolved.service There's no network.service unit, we actually mean network.target here. Reported by Fco. Eduardo Ramírez.

After=systemd-networkd.service network.target
units: systemd-resolved should start before network-online.target and nss-lookup.target (#5691) systemd-resolved provides 1. local API via NSS and D-Bus 2. kind of a local "DNS proxy" through its stub listener The 1st item should be started before nss-lookup.target. The 2nd item should be started before network-online.target, because if the networking works in general, then DNS (and DNS proxy) should too. Fixes #5650

units: make use of the new !! ExecStart= prefix in systemd-resolved.service Let's make use of !! to run resolved with ambient capabilities on systems supporting them.

ExecStart=!!@rootlibexecdir@/systemd-resolved
units: further lock down our long-running services Let's make this an excercise in dogfooding: let's turn on more security features for all our long-running services. Specifically: - Turn on RestrictRealtime=yes for all of them - Turn on ProtectKernelTunables=yes and ProtectControlGroups=yes for most of them - Turn on RestrictAddressFamilies= for all of them, but different sets of address families for each Also, always order settings in the unit files, that the various sandboxing features are close together. Add a couple of missing, older settings for a numbre of unit files. Note that this change turns off AF_INET/AF_INET6 from udevd, thus effectively turning of networking from udev rule commands. Since this might break stuff (that is already broken I'd argue) this is documented in NEWS.

units: switch on ProtectSystem=strict for our long running services Let's step up the protection a notch
2017-02-09 12:58:28 +03:00
ProtectSystem=strict
core: rename ReadOnlySystem= to ProtectSystem= and add a third value for also mounting /etc read-only Also, rename ProtectedHome= to ProtectHome=, to simplify things a bit. With this in place we now have two neat options ProtectSystem= and ProtectHome= for protecting the OS itself (and optionally its configuration), and for protecting the user's data.
