relicense to LGPLv2.1 (with exceptions) We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.

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.

Drop kdbus bits Some kdbus_flag and memfd related parts are left behind, because they are entangled with the "legacy" dbus support. test-bus-benchmark is switched to "manual". It was already broken before (in the non-kdbus mode) but apparently nobody noticed. Hopefully it can be fixed later.

# Ask for the dbus socket.
units: systemd-logind fails hard without dbus That is, without --enable-kdbus and kdbus running. With --enable-kdbus things are more complicated, because dbus might be necessary, if kdbus is missing at runtime. If it is not necessary, the socket will be started, which is not imporant, but not the service.

units: increase watchdog timeout to 3min for all our services 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.

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: restrict namespace for a good number of our own services Basically, we turn it on for most long-running services, with the exception of machined (whose child processes need to join containers here and there), and importd (which sandboxes tar in a CLONE_NEWNET namespace). machined is left unrestricted, and importd is restricted to use only "net"

logind: save/restore session devices and their respective file descriptors This patch ensures that session devices are saved for each session. In order to make the revokation logic work when logind is restarted, the session devices are now saved in the session state files and their respective file descriptors sent to PID1's fdstore in order to keep them open accross restart. This is mandatory in order to keep the revokation logic working. Indeed in case of input-devices, the same file descriptors must be shared by logind and a given session controller in order EVIOCREVOKE to work otherwise multiple sessions can have device access in parallel. This should be the only remaining and missing piece for making logind fully restartable. Fixes: #1163

FileDescriptorStoreMax=512
units: increase LimitNOFILE a bit since we need one fd per session (for logind) and one fd per service (for stdout-syslog-bridge) increase the default rlimit a bit.
