This + should effectively protect the user from rebooting into a + black screen, should the brightness have been set to minimum + by accident. + + * sd-login gained a new sd_machine_get_class() call to + determine the class ("vm" or "container") of a machine + registered with machined. + + * sd-login gained new calls + sd_peer_get_{session,owner_uid,unit,user_unit,slice,machine_name}(), + to query the identity of the peer of a local AF_UNIX + connection. They operate similar to their sd_pid_get_xyz() + counterparts. + + * PID 1 will now maintain a system-wide system state engine + with the states "starting", "running", "degraded", + "maintenance", "stopping". These states are bound to system + startup, normal runtime, runtime with at least one failed + service, rescue/emergency mode and system shutdown. This + state is shown in the "systemctl status" output when no unit + name is passed. It is useful to determine system state, in + particularly when doing so for many systems or containers at + once. + + * A new command "list-machines" has been added to "systemctl" + that lists all local OS containers and shows their system + state (see above), if systemd runs inside of them. + + * systemctl gained a new "-r" switch to recursively enumerate + units on all local containers, when used with the + "list-unit" command (which is the default one that is + executed when no parameters are specified). + + * The GPT automatic partition discovery logic will now honour + two GPT partition flags: one may be set on a partition to + cause it to be mounted read-only, and the other may be set + on a partition to ignore it during automatic discovery. + + * Two new GPT type UUIDs have been added for automatic root + partition discovery, for 32bit and 64bit ARM. This is not + particularly useful for discovering the root directory on + these architectures during bare-metal boots (since UEFI is + not common there), but still very useful to allow booting of + ARM disk images in nspawn with the -i option. + + * MAC addresses of interfaces created with nspawn's + --network-interface= switch will now be generated from the + machine name, and thus be stable between multiple invocations + of the container. + + * logind will now automatically remove all IPC objects owned + by a user if she or he fully logs out. This makes sure that + users who are logged out cannot continue to consume IPC + resources. This covers SysV memory, semaphores and message + queues as well as POSIX shared memory and message + queues. Traditionally SysV and POSIX IPC had no life-cycle + limits, with this functionality this is corrected. This may + be turned off using the RemoveIPC= switch of logind.conf. + + * The systemd-machine-id-setup and tmpfiles tools gained a + --root= switch to operate on a specific root directory, + instead of /. + + * journald can now forward logged messages to the TTYs of all + logged in users ("wall"). This is the default for all + emergency messages now. + + * A new tool systemd-journal-remote has been added to stream + journal log messages across the network. + + * /sys/fs/cgroup/ is now mounted read-only after all cgroup + controller trees are mounted into it. Note that the + directories mounted beneath it are not read-only. This is a + security measure and is particularly useful because glibc + actually includes a search logic to pick any tmpfs it can + find to implement shm_open() if /dev/shm is not available + (which it might very well be in namespaced setups). + + * machinectl gained a new "poweroff" command to cleanly power + down a local OS container. + + * The PrivateDevices= unit file setting will now also drop the + CAP_MKNOD capability from the capability bound set, and + imply DevicePolicy=closed. + + * PrivateDevices=, PrivateNetwork= and PrivateTmp= is now used + comprehensively on all long-running systemd services where + this is appropriate. + + * systemd-udevd will now run in a disassociated mount + namespace. To mount directories from udev rules make sure to + pull in mount units via SYSTEMD_WANTS properties. + + * The kdbus support gained support for uploading policy into + the kernel. sd-bus gained support for creating "monitoring" + connections that can eavesdrop into all bus communication + for debugging purposes. + + * Timestamps may now be specified in seconds since the UNIX + epoch Jan 1st, 1970 by specifying "@" followed by the value + in seconds. + + * Native tcpwrap support in systemd has been removed. tcpwrap + is old code, not really maintained anymore and has serious + shortcomings, and better options such as firewalls + exist. For setups that require tcpwrap usage, please + consider invoking your socket-activated service via tcpd, + like on traditional inetd. + + * A new system.conf configuration option + DefaultTimerAccuracySec= has been added that controls the + default AccuracySec= setting of .timer units. + + * Timer units gained a new WakeSystem= switch. If enabled + timers configured this way will cause the system to resume + from system suspend (if the system supports that, which most + do these days). + + * Timer units gained a new Persistent= switch. If enabled + timers configured this way will save to disk when they have + been last triggered. This information is then used on next + reboot to possible execute overdue timer events, that + couldn't take place because the system was powered off. This + enables simple anacron-like behaviour for timer units. + + * systemctl's "list-timers" will now also list the time a + timer unit was last triggered in addition to the next time + it will be triggered. + + * systemd-networkd will now assign predictable IPv4LL + addresses to its local interfaces. + + Contributions from: Brandon Philips, Daniel Buch, Daniel Mack, + Dave Reisner, David Herrmann, Gerd Hoffmann, Greg + Kroah-Hartman, Hendrik Brueckner, Jason St. John, Josh + Triplett, Kay Sievers, Lennart Poettering, Marc-Antoine + Perennou, Michael Marineau, Michael Olbrich, Miklos Vajna, + Patrik Flykt, poma, Sebastian Thorarensen, Thomas Bächler, + Thomas Hindoe Paaboel Andersen, Tomasz Torcz, Tom Gundersen, + Umut Tezduyar Lindskog, Wieland Hoffmann, Zbigniew + Jędrzejewski-Szmek + + -- Berlin, 2014-03-25 + CHANGES WITH 211: * A new unit file setting RestrictAddressFamilies= has been |
