With the previous improvements, networkd.service's "After=dbus.service" can now
be dropped. That ordering effectively forced networkd.service to run in late
boot only (dbus.service was rejected to run in early boot in
https://bugs.freedesktop.org/show_bug.cgi?id=98254).
Fixes#4504
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.
Add a line
SystemCallFilter=~@clock @module @mount @obsolete @raw-io ptrace
for daemons shipped by systemd. As an exception, systemd-timesyncd
needs @clock system calls and systemd-localed is not privileged.
ptrace(2) is blocked to prevent seccomp escapes.
Apparently, disk IO issues are more frequent than we hope, and 1min
waiting for disk IO happens, so let's increase the watchdog timeout a
bit, for all our services.
See #1353 for an example where this triggers.
./configure --enable/disable-kdbus can be used to set the default
behavior regarding kdbus.
If no kdbus kernel support is available, dbus-dameon will be used.
With --enable-kdbus, the kernel command line option "kdbus=0" can
be used to disable kdbus.
With --disable-kdbus, the kernel command line option "kdbus=1" is
required to enable kdbus support.
The daemon requires the busname unit to operate (on kdbus systems),
since it contains the policy that allows it to acquire its service
name.
