2015-01-07service: automatically create After= dependency from services to their ↵Lennart Poettering
.busname units, if BusName= is set
2015-01-07core: implement serialization/deserialization of fd store elementsLennart Poettering
2015-01-06core: add new logic for services to store file descriptors in PID 1Lennart Poettering
With this change it is possible to send file descriptors to PID 1, via sd_pid_notify_with_fds() which PID 1 will store individually for each service, and pass via the usual fd passing logic on next invocation. This is useful for enable daemon reload schemes where daemons serialize their state to /run, push their fds into PID 1 and terminate, restoring their state on next start from the data in /run and passed in from PID 1. The fds are kept by PID 1 as long as no POLLHUP or POLLERR is seen on them, and the service they belong to are either not dead or failed, or have a job queued.
2014-12-09core: rename unit_destroy_cgroup() to unit_destroy_cgroup_if_empty() since ↵Lennart Poettering
it's not quite as destructive as it sounds nowadays
2014-11-30core: warn and ignore SysVStartPriority=Zbigniew Jędrzejewski-Szmek
Option was being parsed but not used for anything.
2014-11-28core: convert log_unit_*() to log_unit_*_errno()Michal Schmidt
Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_unit_(debug|info|notice|warning|error|emergency)\(([^"]+), "(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_unit_\1_errno(\2, \5, "\3%m"\4);/'
2014-11-28log: fix order of log_unit_struct() to match other logging callsLennart Poettering
Also, while we are at it, introduce some syntactic sugar for creating ERRNO= and MESSAGE= structured logging fields.
2014-11-27log: rearrange log function namingLennart Poettering
- Rename log_meta() → log_internal(), to follow naming scheme of most other log functions that are usually invoked through macros, but never directly. - Rename log_info_object() to log_object_info(), simply because the object should be before any other parameters, to follow OO-style programming style.
2014-11-05core: introduce new Delegate=yes/no property controlling creation of cgroup ↵Lennart Poettering
subhierarchies For priviliged units this resource control property ensures that the processes have all controllers systemd manages enabled. For unpriviliged services (those with User= set) this ensures that access rights to the service cgroup is granted to the user in question, to create further subgroups. Note that this only applies to the name=systemd hierarchy though, as access to other controllers is not safe for unpriviliged processes. Delegate=yes should be set for container scopes where a systemd instance inside the container shall manage the hierarchies below its own cgroup and have access to all controllers. Delegate=yes should also be set for user@.service, so that systemd --user can run, controlling its own cgroup tree. This commit changes machined, systemd-nspawn@.service and user@.service to set this boolean, in order to ensure that container management will just work, and the user systemd instance can run fine.
2014-10-28service: add missing state table entryLennart Poettering
2014-10-28core: send sigabrt on watchdog timeout to get the stacktraceUmut Tezduyar Lindskog
if sigabrt doesn't do the job, follow regular shutdown routine, sigterm > sigkill.
2014-10-22sd-bus: rename sd_bus_get_owner_uid(), sd_bus_get_owner_machine_id() and ↵Daniel Mack
sd_bus_get_peer_creds() Clean up the function namespace by renaming the following: sd_bus_get_owner_uid() → sd_bus_get_name_creds_uid() sd_bus_get_owner_machine_id() → sd_bus_get_name_machine_id() sd_bus_get_peer_creds() → sd_bus_get_owner_creds()
2014-10-12Set $NOTIFY_SOCKET for control procs if NotifyAccess=allBrandon L Black
2014-10-09service: enter SERVICE_STOP_SIGTERM state after getting "STOPPING=1"Michal Schmidt
SERVICE_STOP would mean we're running the ExecStop command. That's not the case with "STOPPING=1". Instead we should enter the same state as if we just told the service to stop, i.e. SERVICE_STOP_SIGTERM. This fixes a bug where voluntarily exiting services would hang around in deactivating state until timeout.
2014-09-19socket: introduce SELinuxContextFromNet optionMichal Sekletar
This makes possible to spawn service instances triggered by socket with MLS/MCS SELinux labels which are created based on information provided by connected peer. Implementation of label_get_child_mls_label derived from xinetd. Reviewed-by: Paul Moore <pmoore@redhat.com>
2014-09-08service: hook up custom endpoint logicDaniel Mack
If BusPolicy= was passed, the parser function will have created an ExecContext->bus_endpoint object, along with policy information. In that case, create a kdbus endpoint, and pass its path name to the namespace logic, to it will be mounted over the actual 'bus' node. At endpoint creation time, no policy is updloaded. That is done after fork(), through a separate call. This is necessary because we don't know the real uid of the process earlier than that.
2014-09-05exec: factor out most function arguments of exec_spawn() to ExecParametersDaniel Mack
This way, the list of arguments to that function gets more comprehensive, and we can get around passing lots of NULL and 0 arguments from socket.c, swap.c and mount.c. It also allows for splitting up the code in exec_spawn(). While at it, make ExecContext const in execute.c.
2014-08-22core: add support for a configurable system-wide start-up timeoutLennart Poettering
When this system-wide start-up timeout is hit we execute one of the failure actions already implemented for services that fail. This should not only be useful on embedded devices, but also on laptops which have the power-button reachable when the lid is closed. This devices, when in a backpack might get powered on by accident due to the easily reachable power button. We want to make sure that the system turns itself off if it starts up due this after a while. When the system manages to fully start-up logind will suspend the machine by default if the lid is closed. However, in some cases we don't even get as far as logind, and the boot hangs much earlier, for example because we ask for a LUKS password that nobody ever enters. Yeah, this is a real-life problem on my Yoga 13, which has one of those easily accessible power buttons, even if the device is closed.
2014-08-21service: allow services of Type=oneshot that specify no ExecStart= commandsLennart Poettering
This is useful for services that simply want to run something on shutdown, but not at bootup. They should only set ExecStop= but leave ExecStart= unset.
2014-08-21service: use the right timeout for stop processes we forkLennart Poettering
2014-08-21core: allow informing systemd about service status changes with RELOADING=1 ↵Lennart Poettering
and STOPPING=1 sd_notify() messages
2014-08-21service,strv: introduce strv_find_startswith() and make use of itLennart Poettering
Unlike strv_find_prefix() the new call will return a pointer to the suffix of the item we found, instead of the whole item. This is more closer inline with what startswith() does, and allows us to simplify a couple of invocations.
2014-08-21service: don't invoke functions at the same time as declaring variablesLennart Poettering
2014-08-21service: remove some pointless linebreaks, to make things more readableLennart Poettering

2014-08-21core: unify how we generate the prefix string when dumping unit stateLennart Poettering
2014-07-18core: show timeouts when watchdog howlsZbigniew Jędrzejewski-Szmek
2014-07-07service: flush status text and errno values each time a service is startedLennart Poettering
We shouldn't show status texts from previous service starts
2014-07-07service: don't accept negative ERRNO= notification messagesLennart Poettering
2014-07-07service: minor modernizationLennart Poettering
2014-07-07core: Added support for ERRNO NOTIFY_SOCKET message parsing, and added ↵Miguel Angel Ajo
StatusErrno dbus property along StatusText to allow notification of numeric status condition while degraded service operation or any other special situation.
2014-07-03core: introduce exit_status_set_is_empty() to make things a bit easier to readLennart Poettering
2014-07-03exit-status: rename ExitStatusSet's "code" field to "status"Lennart Poettering
We should follow the naming scheme waitid() uses, not come up with our own reversed one...
2014-07-03core: introduce new RestartForceExitStatus= service settingLennart Poettering
This does the inverse of RestartPreventExitStatus=: it forces a restart of a service when a certain exit status is returned by a service process.
2014-06-07Remove sysv parser from service.cThomas Hindoe Paaboel Andersen
Parsing sysv files was moved to the sysv-generator in the previous commit. This patch removes the sysv parsing from serivce.c. Note that this patch drops the following now unused sysv-specific info from service dump: "SysV Init Script has LSB Header: (yes/no)" "SysVEnabled: (yes/no)" "SysVRunLevels: (levels)"
2014-06-05core: introduce new Restart=on-abnormal settingLennart Poettering
Restart=on-abnormal is similar to Restart=on-failure, but avoids restarts on unclean exit codes (but still doing restarts on all obviously unclean exits, such as timeouts, signals, coredumps, watchdog timeouts). Also see: https://fedorahosted.org/fpc/ticket/191

2014-05-14core: sysvcompat - avoid repeated function callTom Gundersen
2014-05-14core: sysvcompat - $network should be equivalent to network-online, rather ↵Tom Gundersen
than network target Most likely the facility needed is actual connectivity, rather than whether or not the network managment daemon is running. We also need to explicitly pull in the network-online.target, as it is not active by default. This means {systemd-networkd,NetworkManager}-wait-online.service, can be enabled by default as part of network-online.target, and only delay boot when some service actively pulls it in.

2014-04-24service: rename StartLimitAction enum to FailureActionMichael Olbrich
It's used for the FailureAction property as well.
2014-04-24service: add FailureAction= optionMichael Olbrich
It has the same possible values as StartLimitAction= and is executed immediately if a service fails.
2014-04-21service: add support for reboot argument when triggered by StartLimitAction=Michael Olbrich
When rebooting with systemctl, an optional argument can be passed to the reboot system call. This makes it possible the specify the argument in a service file and use it when the service triggers a restart. This is useful to distinguish between manual reboots and reboots caused by failing services.
2014-03-24service: don't take chkconfig priority into accountLennart Poettering
Given that native services do not carry a sysv priority anyway it is pointless reading them from chkconfig headers, and pretend they'd work. So let's drop this.
2014-03-24sd-event: rework API to support CLOCK_REALTIME_ALARM and ↵Lennart Poettering
CLOCK_BOOTTIME_ALARM, too
2014-03-19core: rework context initialization/destruction logicLennart Poettering
Let's automatically initialize the kill, exec and cgroup contexts of the various unit types when the object is constructed, instead of invididually in type-specific code. Also, when PrivateDevices= is set, set DevicePolicy= to closed.
2014-03-18util: replace close_nointr_nofail() by a more useful safe_close()Lennart Poettering
safe_close() automatically becomes a NOP when a negative fd is passed, and returns -1 unconditionally. This makes it easy to write lines like this: fd = safe_close(fd); Which will close an fd if it is open, and reset the fd variable correctly. By making use of this new scheme we can drop a > 200 lines of code that was required to test for non-negative fds or to reset the closed fd variable afterwards.
2014-03-17core, libsystemd, systemd, timedate, udev: spelling fixesMiklos Vajna
2014-03-16Use strlen even for constant stringsJosh Triplett
GCC optimizes strlen("string constant") to a constant, even with -O0. Thus, replace patterns like sizeof("string constant")-1 with strlen("string constant") where possible, for clarity. In particular, for expressions intended to add up the lengths of components going into a string, this often makes it clearer that the expression counts the trailing '\0' exactly once, by putting the +1 for the '\0' at the end of the expression, rather than hidden in a sizeof in the middle of the expression.
2014-03-03core: introduce new RuntimeDirectory= and RuntimeDirectoryMode= unit settingsLennart Poettering
As discussed on the ML these are useful to manage runtime directories below /run for services.
