It is capable up bridges, VLANs and bonding. This + currently provides no hookups for interactive network + configuration. Use this for your initrd, container, embedded + or server setup, if you need a simple, yet powerful network + configuration solution. This configuration subsystem is + quite nifty as it allows wildcard hotplug matching in + interfaces. For example, with a single configuration snippet + you can configure that all ethernet interfaces showing up + are automatically added to a bridge, or similar. It + optionally supports link-sensing and more. + + * A new tool "systemd-socket-proxyd" has been added which can + acts as a bidirectional proxy for TCP sockets. This is + useful for adding socket activation support to services that + do not actually support socket activation, including virtual + machines and suchlike. + + * Add a new tool to save/restore rfkill state on + shutdown/boot. + + * Save/restore state of kbd backlights in addition to display + backlights on shutdown/boot. + + * udev learned a new SECLABEL{} construct to label device + nodes with a specific security label when they appear. For + now only SECLABEL{selinux} is supported, but the syntax is + prepared for additional security frameworks. + + * udev gained a new scheme to configure link-level attributes + from files in /etc/systemd/network/*.link. These files can + match against MAC address, device path, driver name and type + and will apply attributes like the naming policy, link speed + MTU, duplex settings, WakeOnLan settings, MAC address, MAC + address assignment policy (randomized, ...). + + * When the User= switch is used in a unit file, also + initialize $SHELL= based on user database. + + * systemd no longer depends on libdbus. All communication is + now done with sd-bus, systemd's low-level bus library + implementation. + + * kdbus support has been added to PID 1 itself. When kdbus is + enabled this causes PID 1 to set up the system bus, and + enable support for a new ".busname" unit type that + encapsulates bus name activation on kdbus. It works a little + bit like ".socket" units, except for bus names. A new + generator has been added that converts classic dbus1 service + activation files automatically into native systemd .busname + and .service units. + + * sd-bus: add a light-weight vtable implementation that allows + defining objects on the bus with a simple static const + vtable array of its methods, signals and properties. + + * systemd will not generate nor install static dbus + introspection data anymore to /usr/share/dbus-1/interfaces, + as the precise format of these files are unclear, and + nothing makes use of it. + + * A proxy daemon is now provided to proxy clients connecting + via classic D-Bus AF_UNIX sockets to kdbus, to provide full + compatibility with classic D-Bus. + + * A bus driver implementation has been added that supports the + classic D-Bus bus driver calls on kdbus, also for + compatibility purposes. + + * A new API "sd-event.h" has been added that implements a + minimal event loop API built around epoll. It provides a + couple of features that direct epoll usage is lacking: + priorization of events, scales to large numbers of timer + events, per-event timer slack (accuracy), system-wide + coalescing of timer events, exit handlers, watchdog + supervision support using systemd's sd_notify() API, child + process handling. + + * A new API "sd-rntl.h" has been added that provides an API + around the route netlink interface of the kernel, similar in + style to "sd-bus.h". + + * A new API "sd-dhcp.h" has been added that provides a small + DHCPv4 client side implementation. This is used by + "systemd-networkd". + + * There's a new kernel command line option + "systemd.restore_state". When set none of the systemd tools + will restore saved runtime state to hardware devices. More + specifically, the rfkill and backlight states are not + restored. + + * The FsckPassNo= compatibility option in mount/service units + has been removed. The fstab generator will now add the + necessary dependencies automatically, and does not require + PID1's support for that anymore. + + * journalctl gained a new switch --list-boots, that lists + recent boots with their times and boot IDs. + + * The various tools like systemctl, loginctl, timedatectl, + busctl, systemd-run, ... have gained a new switch "-M" to + connect to a specific, local OS container (as direct + connection, without requiring SSH). This works on any + container that is registered with machined, such as those + created by libvirt-lxc or nspawn. + + * systemd-run and systemd-analyze also gained support for "-H" + to connect to remote hosts via SSH. This is particular + useful for systemd-run since it enables queuing of jobs onto + remote systems. + + * machinectl gained a new command "login" to open a getty + login in any local container. This works with any container + that is registered with machined (such as those created by + libvirt-lxc or nspawn), and which run systemd inside. + + * machinectl gained a new "reboot" command that may be used to + trigger a reboot on a specific container that is registered + with machined. This works on any container that runs an init + system of some kind. + + * systemctl gained a new "list-timers" command to print a nice + listing of installed timer units with the times they elapse + next. + + * Alternative reboot() parameters may now be specified on the + "systemctl reboot" command line and are passed to the + reboot() system call. + + * systemctl gained a new --job-mode= switch to configure the + mode to queue a job with. This is a more generic version of + --fail, --irreversible, --ignore-dependencies which are + still available but not advertised anymore. + + * systemd-activate gained a new --setenv= parameter to specify + additional environment variables to pass to the executed + program. + + * /etc/systemd/system.conf gained new settings to configure + various default timeouts of units, as well as the default + start limit interval and burst. These may still be overriden + within each Unit. + + * PID1 will now export profile data of security policy + uploading (such as SELinux policy upload to the kernel) + over. + + * journald: when forwarding logs to the console include + timestamps. + + * OnCalendar= in timer units now understands the special + strings "yearly" and "annually". (Both are equivalent) + + * The accuracy of timer units is now configurable with the new + AccuracySec= setting. It defaults to 1min. + + * A new dependency type JoinsNamespaceOf= has been added that + allows running two services within the same /tmp and network + namespace, if PrivateNetwork= or PrivateTmp= are used. + + * A new command "cat" has been added to systemctl. It outputs + the original unit file of a unit, and concatenates the + contents of addition "drop-in" unit file snippets to it, so + that the full configuration is shown. + + * systemctl now supports globbing on the various "list-xyz" + commands, like "list-units" or "list-sockets", as well as on + thsoe commands which take multiple unit names. + + * All systemd daemons now make use of the watchdog logic so + that systemd automatically notices when they hang. + + * If the $container_ttys environment variable is set + getty-generator will automatically spawn a getty for each + listed tty. This is useful for container managers to request + login gettys to be spawned on as many ttys as needed. + + * %h, %s, %U specifier support is not available anymore when + used in unit files for PID 1. This is because NSS calls are + not safe from PID 1. They stay available for --user + instances of systemd, and as special case for the root user. + + * When the kernel command line argument "kdbus" is specified + systemd will automatically load the kdbus kernel + module. This is useful for testing kdbus without having to + turn it on unconditionally. + + * loginctl gained a new "--no-legend" switch to turn off output + of the legend text. + + * The "sd-login.h" API gained three new calls: + sd_session_is_remote(), sd_session_get_remote_user(), + sd_session_get_remote_host() to query information about + remote sessions. + + * The udev device database now also carries vendor/product + information about SDIO devices. + + * The "sd-daemon.h" API gained a new sd_watchdog_enabled() to + determine whether watchdog notifications are requested by + the system manager. + + * "systemd-delta" will now also display changes made via .d/ + drop-ins for unit files. + + * Socket-activated per-connection services will now include a + short description of the connection parameters in the + description. + + * tmpfiles gained a new "--boot" option. When this is not used + only lines where the command character is not suffixed with + "!" are executed. When this option is specified those + options are executed too. This is useful to ensure that + specific lines are not executed by accident during runtime, + and only at boot (for example, a line that creates + /run/nologin). + + * A new API "sd-resolv.h" has been added, that provides a + simple asynchronous around glibc NSS host name resolution + calls, such as getaddrinfo(). In contrast to glibc's + getaddrinfo_a() it does not use signals. In contrast to most + other asynchronous name resolution libraries this one does + not not reimplement DNS, but reused NSS, so that alternative + host name resolution systems continue to work, such as mDNS, + LDAP, ... This API is based on libasyncns, but has been + cleaned up for inclusion in systemd. + + * journalctl's --unit= switch gained support for globbing. + + * The APIs "sd-journal.h", "sd-login.h", "sd-id128.h" are no + longer found in individual libraries libsystemd-journal.so, + libsystemd-login.so, libsystemd-id128.so. Instead we have + merged them into a single library libsystemd.so which + provides all symbols. The reason for this are cyclic + dependencies, as these libraries tend to use each other's + symbols. So far we maneged to work-around that by linking a + copy of a good part of our code into each of these libraries + again and again, which however makes certain things hard to + do, like sharing static variables. Also, it substantially + increases footprint. With this change there's only one + library for the basic APIs systemd provides. Also, + "sd-bus.h", "sd-memfd.h", "sd-event.h", "sd-rtnl.h", + "sd-resolve.h", "sd-utf8.h" are found in this library as + well, however are subject to the --enable-kdbus switch (see + below). Note that "sd-dhcp.h" and "sd-daemon.h" are not part + of this libraries (the former because it only consumes, + never provides services of/to other APIs, and the latter + because it is completely standalone). To make the transition + from the separate libraries to the unified one easy we + provide the --enable-compat-libs compile time switch which + will generate stub libraries that are compatible with the + old ones but redirect all calls to the new one. + + * All the kdbus logic and the new APIs "sd-bus.h", + "sd-memfd.h", "sd-event.h", "sd-rtnl.h", "sd-resolve.h", + "sd-utf8.h" is compile-time optional, via the + "--enable-kdbus" switch and is not compiled in by + default. To make use of you have to explicitly enable the + switch. Note however, that neither the kernel nor the + userspace API for all of this is considered stable yet. We + want to maintain the freedom to still change the APIs for + now. By specifying this build-time switch you acknowledge + that you are aware of the instability of the current + APIs. Also, note that while kdbus is pretty much complete, + it lacks one thing: proper policy support. This means you + can build a fully working system with all features, however + it will be highly insecure. Policy will be added in one of + the next releases, at the same time as we will declare the + APIs stable. + + * systemctl gained a new "import-environment" command which + uploads the callers environment (or parts thereof) into the + service manager so that it is inherited by services started + by the manager. This is useful to upload variables like + $DISPLAY into the user service manager. + + * A new PrivateDevices= switch has been added to service units + which allows running a service with a namespaced /dev + directory that does not contain any device nodes for + physical devices. More specifically it only includes devices + such as /dev/null, /dev/urandom and /dev/zero which are API + entry points. + + * logind has been extended to support behaviour like VT + switching on seats that do not support a VT. This makes + multi-session available on seats that are not the first seat + (seat0), and on systems where kernel support for VTs has + been disabled at compile time. + + * If a process holds a delay lock for system sleep or shutdown + and fails to release it in time we will now log about its + identity. This makes it easier to identify processes that + cause slow suspends or power-offs. + + * When parsing /etc/crypttab, support a new key-slot= option + as supported by Debian, which allows indicating which LUKS + slot to use on disk. + + * The boot-time has been improved to show information about + timeouts that are expiring as they are expiring. + + * The sd_journald_sendv() API call has been updated to be + async-signal-safe so that it may be invoked from signal + handlers for logging purposes. + + * Boot-time status output is now enabled automatically after a + short timeout if boot does not progress, in order to give + the user an indication what he is waiting for. + + * The KillMode= switch in service units gained a new possible + value "mixed". If set and the unit is shutdown then the + initial SIGTERM signal is sent only to the main daemon + process, while the following SIGKILL signal is then sent to + all remaining processes of the service. + + * When a scope unit is registered a new property "Controller" + may be set. If set to a valid bus name systemd will send a + RequestStop() signal to this name when it would like to shut + down the scope. This may be used to hook manager logic into + the shutdown logic of scope units. Also, scope units may now + be put in a special "abandoned" state in which case the + manager process which created them takes no further + responsibilities for it. + + * When reading unit files systemd will now implicitly verify + the access mode of these files, and warn about certain + suspicious combinations. This has been added to make it + easier to track down packaging bugs where unit files are + marked executable or world-writable. + + * systemd-nspawn gained a new "--setenv=" switch to set + container-wide environment variables. + + * systemd-nspawn has been updated to create a new kdbus domain + for each container that is invoked, thus allowing each + container to have its own set of system and user busses, + independently of the host. + + * systemd-nspawn gained a new --drop-capability= switch to run + the container with less capabilities than the default. Both + --drop-capability= and --capability= now take the specia + string "all" for dropping or keeping all capabilities. + + * systemd-nspawn gained new switches for executing containers + with specific SELinux labels set. + + * systemd-nspawn gained a new --quiet switch to not generate + any additional output but the container's own console + output. + + * systemd-nspawn gained a new --share-system switch to run a + container without PID namespacing enabled. + + * systemd-nspawn gained a new --register= switch to control + whether the container is registered with machined or + not. This is useful for containers that do not register full + OS images, but only specific apps. + + * systemd-nspawn gained a new --keep-unit which may be used + when invoked as only program from a service unit, and + results in registration of the unit service itself in + machined, instead of a newly opened scope unit. + + * systemd-nspawn gained a new --network-interface= switch for + moving arbitrary interfaces to the container. The new + --network-veth switch creates a virtual ethernet connection + between host and container. Thew new --network-bridge= + switch then additionally allows assigning the host side of + this virtual ethernet connection to a bridge device. + + * logind will now also track a "Desktop" identifier for each + session which encodes the desktop environment of it. This is + useful for desktop environments that want to identify + multiple running sessions of itself easily. + + * A new SELinuxContext= setting for service units has been + added that allows setting a specific SELinux execution + context for a service. + + * Most systemd client tools will now honour $SYSTEMD_LESS for + settings of the "less" pager. By default, these tools will + override $LESS to allow certain operations like + jump-to-the-end work. With $SYSTEMD_LESS it is possible to + influence this logic. + + * systemd's "seccomp" hook-up has been changed to make use of + the libseccomp library instead of using its own + implementation. This has benefits for portability among + other things. + + * For usage together with SystemCallFilter= a new + SystemCallErrorNumber= setting has been introduce that + allows configuration if a system error number to return on + filtered syscalls, instead of immediately killing the + process. Also, SystemCallArchitectures= has been added to + limit access to system calls of a particular architecture + (in order to turn off support for unused secondary + architectures). There's also a global + SystemcallArchitecture= setting in system.conf now to turn + off support for non-native system calls system-wide. + + Contributions from: Adam Williamson, Alex Jia, Anatol Pomozov, + Ansgar Burchardt, AppleBloom, Auke Kok, Bastien Nocera, + Chengwei Yang, Christian Seiler, Colin Guthrie, Colin Walters, + Cristian Rodríguez, Daniel Buch, Daniele Medri, Daniel J + Walsh, Daniel Mack, Dan McGee, Dave Reisner, David Coppa, + David Herrmann, David Strauss, Djalal Harouni, Dmitry Pisklov, + Elia Pinto, Florian Weimer, George McCollister, Goffredo + Baroncelli, Greg Kroah-Hartman, Hendrik Brueckner, Igor + Zhbanov, Jan Engelhardt, Jan Janssen, Jason A.
