machined: split out machine registration stuff from logind Embedded folks don't need the machine registration stuff, hence it's nice to make this optional. Also, I'd expect that machinectl will grow additional commands quickly, for example to join existing containers and suchlike, hence it's better keeping that separate from loginctl.

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.

meson: use jinja2 for unit templates We don't need two (and half) templating systems anymore, yay! I'm keeping the changes minimal, to make the diff manageable. Some enhancements due to a better templating system might be possible in the future. For handling of '## ' — see the next commit.

units: set NoNewPrivileges= for all long-running services Previously, setting this option by default was problematic due to SELinux (as this would also prohibit the transition from PID1's label to the service's label). However, this restriction has since been lifted, hence let's start making use of this universally in our services. On SELinux system this change should be synchronized with a policy update that ensures that NNP-ful transitions from init_t to service labels is permitted. An while we are at it: sort the settings in the unit files this touches. This might increase the size of the change in this case, but hopefully should result in stabler patches later on. Fixes: #1219

machined: move logic for bind mounting into containers from machinectl to machined This extends the bus interface, adding BindMountMachine() for bind mounting directories from the host into the container.
2015-02-17 19:19:57 +03:00
# Note that machined cannot be placed in a mount namespace, since it
# needs access to the host's mount namespace in order to implement the
# "machinectl bind" operation.
