Fix preset-all
2016-08-19units: install user units as real files, not symlinks to ../system/Zbigniew Jędrzejewski-Szmek
This was causing preset-all --global to create symlinks: $ systemctl preset-all --global --root=/var/tmp/inst1 Created symlink /var/tmp/inst1/etc/systemd/user/shutdown.target → /usr/lib/systemd/user/../system/shutdown.target. Created symlink /var/tmp/inst1/etc/systemd/user/sockets.target → /usr/lib/systemd/user/../system/sockets.target. Created symlink /var/tmp/inst1/etc/systemd/user/timers.target → /usr/lib/systemd/user/../system/timers.target. Created symlink /var/tmp/inst1/etc/systemd/user/paths.target → /usr/lib/systemd/user/../system/paths.target. Created symlink /var/tmp/inst1/etc/systemd/user/bluetooth.target → /usr/lib/systemd/user/../system/bluetooth.target. Created symlink /var/tmp/inst1/etc/systemd/user/printer.target → /usr/lib/systemd/user/../system/printer.target. Created symlink /var/tmp/inst1/etc/systemd/user/sound.target → /usr/lib/systemd/user/../system/sound.target. Created symlink /var/tmp/inst1/etc/systemd/user/smartcard.target → /usr/lib/systemd/user/../system/smartcard.target. Created symlink /var/tmp/inst1/etc/systemd/user/busnames.target → /usr/lib/systemd/user/../system/busnames.target. It is better to create units in a state that completely matches the presets, i.e. preset-all should do nothing when invoked immediately after installation. I'm sure it was confusing to users too, suggesting that system and user units may somehow alias each other.
2016-08-13units: do not start load-random-seed in containers (#3941)Zbigniew Jędrzejewski-Szmek
Random numbers are provided by the host kernel, we don't need to do anything. https://bugzilla.redhat.com/show_bug.cgi?id=1329124
2016-08-02units: add graphical-session-pre.target user unit (#3848)Martin Pitt
This complements graphical-session.target for services which set up the environment (e. g. dbus-update-activation-environment) and need to run before the actual graphical session.

2016-07-27vconsole: Don't do static installation under sysinit.targetMichal Soltys
Udev rules cover all the necessary initializations. As the service now is neither installed, nor installable - we can remove explicit dependencies and RemainAfterExit=yes option.
2016-07-25units: add graphical-session.target user unit (#3678)Martin Pitt
This unit acts as a dynamic "alias" target for any concrete graphical user session like gnome-session.target; these should declare "BindsTo=graphical-session.target" so that both targets stop and start at the same time. This allows services that run in a particular graphical user session (e. g. gnome-settings-daemon.service) to declare "PartOf=graphical-session.target" without having to know or get updated for all/new session types. This will ensure that stopping the graphical session will stop all services which are associated to it.
2016-07-25getty@.service.m4: add Conflicts=/Before= against rescue.service (#3792)Michal Soltys
If user isolates rescue target from multi-user or graphical target (or just starts the service), IgnoreOnIsolate will cause issues with sulogin which is directly started on current virtual console. This patch adds necessary Conflicts= and Before= against rescue.service. Note that this is not needed for emergency target, as implicit Requires= and After= against sysinit.target is in effect for this service (DefaultDependencies=yes).

2016-07-21nspawn: enable major=0/minor=0 devices inside the container (#3773)Alessandro Puccetti
https://github.com/systemd/systemd/pull/3685 introduced /run/systemd/inaccessible/{chr,blk} to map inacessible devices, this patch allows systemd running inside a nspawn container to create /run/systemd/inaccessible/{chr,blk}.
2016-07-20units: fix TasksMax=16384 for systemd-nspawn@.serviceLennart Poettering
When a container scope is allocated via machined it gets 16K set already since cf7d1a30e44bf380027a2e73f9bf13f423a33cc1. Make sure when a container is run as system service it gets the same values.

2016-06-23udev: bump TasksMax to inifinity (#3593)Franck Bui
udevd already limits its number of workers/children: the max number is actually twice the number of CPUs the system is using. (The limit can also be raised with udev.children-max= kernel command line option BTW). On some servers, this limit can easily exceed the maximum number of tasks that systemd put on all services, which is 512 by default. Since udevd has already its limitation logic, simply disable the static limitation done by TasksMax.
2016-06-22units: add nosuid and nodev options to tmp.mount (#3575)Martin Pitt
This makes privilege escalation attacks harder by putting traps and exploits into /tmp. https://bugs.debian.org/826377
2016-06-21units: machined needs mount-related syscalls for its namespacing operationsLennart Poettering
Specifically "machinectl shell" (or its OpenShell() bus call) is implemented by entering the file system namespace of the container and opening a TTY there. In order to enter the file system namespace, chroot() is required, which is filtered by SystemCallFilter='s @mount group. Hence, let's make this work again and drop @mount from the filter list.
2016-06-21emergency.service: Don't say "Welcome" when it's an emergency (#3569)Lennart Poettering
Quoting @cgwalters: Just uploading this as an RFC. Now I know reading the code that systemd says `Welcome to $OS` as a generic thing, but my initial impression on seeing this was that it was almost sarcastic =) Let's say "You are in emergency mode" as a more neutral/less excited phrase. This patch is based on #3556, but makes the same change for rescue mode.
2016-06-21resolved: respond to local resolver requests on 127.0.0.53:53Lennart Poettering
In order to improve compatibility with local clients that speak DNS directly (and do not use NSS or our bus API) listen locally on 127.0.0.53:53 and process any queries made that way. Note that resolved does not implement a full DNS server on this port, but simply enough to allow normal, local clients to resolve RRs through resolved. Specifically it does not implement queries without the RD bit set (these are requests where recursive lookups are explicitly disabled), and neither queries with DNSSEC DO set in combination with DNSSEC CD (i.e. DNSSEC lookups with validation turned off). It also refuses zone transfers and obsolete RR types. All lookups done this way will be rejected with a clean error code, so that the client side can repeat the query with a reduced feature set. The code will set the DNSSEC AD flag however, depending on whether the data resolved has been validated (or comes from a local, trusted source). Lookups made via this mechanisms are propagated to LLMNR and mDNS as necessary, but this is only partially useful as DNS packets cannot carry IP scope data (i.e. the ifindex), and hence link-local addresses returned cannot be used properly (and given that LLMNR/mDNS are mostly about link-local communication this is quite a limitation). Also, given that DNS tends to use IDNA for non-ASCII names, while LLMNR/mDNS uses UTF-8 lookups cannot be mapped 1:1. In general this should improve compatibility with clients bypassing NSS but it is highly recommended for clients to instead use NSS or our native bus API. This patch also beefs up the DnsStream logic, as it reuses the code for local TCP listening. DnsStream now provides proper reference counting for its objects. In order to avoid feedback loops resolved will no silently ignore 127.0.0.53 specified as DNS server when reading configuration. resolved listens on 127.0.0.53:53 instead of 127.0.0.1:53 in order to leave the latter free for local, external DNS servers or forwarders. This also changes the "etc.conf" tmpfiles snippet to create a symlink from /etc/resolv.conf to /usr/lib/systemd/resolv.conf by default, thus making this stub the default mode of operation if /etc is not populated.
2016-06-13units: tighten system call filters a bitLennart Poettering
Take away kernel keyring access, CPU emulation system calls and various debug system calls from the various daemons we have.
2016-06-09units: add a basic SystemCallFilter (#3471)Topi Miettinen
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.
2016-06-08units: enable MemoryDenyWriteExecute (#3459)Topi Miettinen

2016-06-01units: wait for plymouth to shut down in rescue.sevice (#3367)Franck Bui
In the same vein as commit ac59f0c12c117b9bb5b7e17f33987b0107791239 which added the --wait option to the emergency service, this patch makes sure that plymouth has exited before entering into the rescue mode.
2016-05-21units: restore ConditionNeesUpdate=/etc in ldconfig.service (#3311)Lennart Poettering
In order to support stateless systems that support offline /usr updates properly, let's restore the ConditionNeesUpdate=/etc line that makes sure we are run when /usr is updated and this update needs to be propagated to the /etc/ld.so.conf file stored in /etc. This reverts part of #2859, which snuck this change in, but really shouldn't have.
2016-05-12Create initrd-root-device.target synchronization point (#3239)Daniel Drake
Add a synchronization point so that custom initramfs units can run after the root device becomes available, before it is fsck'd and mounted. This is useful for custom initramfs units that may modify the root disk partition table, where the root device is not known in advance (it's dynamically selected by the generators).
2016-05-10units: make sure that fsck is executed before quotachecktblume
fsck determines wheter an automatic quotacheck should be executed. Hence fsck service needs to run before quotacheck service.
2016-04-27Stop syslog.socket when entering emergency mode (#3130)Martin Pitt
When enabling ForwardToSyslog=yes, the syslog.socket is active when entering emergency mode. Any log message then triggers the start of rsyslog.service (or other implementation) along with its dependencies such as local-fs.target and sysinit.target. As these might fail themselves (e. g. faulty /etc/fstab), this breaks the emergency mode. This causes syslog.socket to fail with "Failed to queue service startup job: Transition is destructive". Add Conflicts=syslog.socket to emergency.service to make sure the socket is stopped when emergency.service is started. Fixes #266

2016-04-22units: order systemd-user-sessions.service after network.targetLennart Poettering
That way we can be sure that local users are logged out before the network is shut down when the system goes down, so that SSH session should be ending cleanly before the system goes down. Fixes: #2390

2016-04-21units: Add "GuessMainPID=no" to compatibility unit for rc-local (#3018)Calvin Owens
With the current "Type=forking", systemd tries to guess the PID it should wait on at reboot (because we have no "PIDFile="). Depending on how wrong the guess is, we can end up hanging forever at reboot. Asking it not to do that eliminates the problem.
2016-03-17units: run ldconfig.service after we have mounted all local file systemsMichal Sekletar
Also drop ConditionNeedsUpdate=|/etc. Regardless if system is updated online or offline, updating dynamic loader cache should always be responsibility of packaging tools/scripts.
2016-02-26Don't escape the name of the container in instances ofElias Probst
When using `%I` for instances of `systemd-nspawn@.service`, the result will be `systemd-nspawn` trying to launch a container named e.g. `fedora/23` instead of `fedora-23`. Using `%i` instead prevents escaping `-` in a container name and uses the unmodified container name from the machine store.

This commit rips out systemd-bootchart. It will be given a new home, outside of the systemd repository. The code itself isn't actually specific to systemd and can be used without systemd even, so let's put it somewhere else.
2016-02-12remove bus-proxydDaniel Mack
As kdbus won't land in the anticipated way, the bus-proxy is not needed in its current form. It can be resurrected at any time thanks to the history, but for now, let's remove it from the sources. If we'll have a similar tool in the future, it will look quite differently anyway. Note that stdio-bridge is still available. It was restored from a version prior to f252ff17, and refactored to make use of the current APIs.

2016-02-10coredump: rework coredumping logicLennart Poettering
This reworks the coredumping logic so that the coredump handler invoked from the kernel only collects runtime data about the crashed process, and then submits it for processing to a socket-activate coredump service, which extracts a stacktrace and writes the coredump to disk. This has a number of benefits: the disk IO and stack trace generation may take a substantial amount of resources, and hence should better be managed by PID 1, so that resource management applies. This patch uses RuntimeMaxSec=, Nice=, OOMScoreAdjust= and various sandboxing settings to ensure that the coredump handler doesn't take away unbounded resources from normally priorized processes. This logic is also nice since this makes sure the coredump processing and storage is delayed correctly until /var/systemd/coredump is mounted and writable. Fixes: #2286
