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: 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

units: add ProtectClock=yes Add `ProtectClock=yes` to systemd units. Since it implies certain `DeviceAllow=` rules, make sure that the units have `DeviceAllow=` rules so they are still able to access other devices. Exclude timesyncd and timedated.

User=systemd-journal-remote
meson: allow WatchdogSec= in services to be configured As discussed on systemd-devel [1], in Fedora we get lots of abrt reports about the watchdog firing [2], but 100% of them seem to be caused by resource starvation in the machine, and never actual deadlocks in the services being monitored. Killing the services not only does not improve anything, but it makes the resource starvation worse, because the service needs cycles to restart, and coredump processing is also fairly expensive. This adds a configuration option to allow the value to be changed. If the setting is not set, there is no change. My plan is to set it to some ridiculusly high value, maybe 1h, to catch cases where a service is actually hanging.

units: bump the RLIMIT_NOFILE soft limit for all services that access the journal This updates the unit files of all our serviecs that deal with journal stuff to use a higher RLIMIT_NOFILE soft limit by default. The new value is the same as used for the new HIGH_RLIMIT_NOFILE we just added. With this we ensure all code that access the journal has higher RLIMIT_NOFILE. The code that runs as daemon via the unit files, the code that is run from the user's command line via C code internal to the relevant tools. In some cases this means we'll redundantly bump the limits as there are tools run both from the command line and as service.
