2015-10-06core: add support for naming file descriptors passed using socket activationLennart Poettering
This adds support for naming file descriptors passed using socket activation. The names are passed in a new $LISTEN_FDNAMES= environment variable, that matches the existign $LISTEN_FDS= one and contains a colon-separated list of names. This also adds support for naming fds submitted to the per-service fd store using FDNAME= in the sd_notify() message. This also adds a new FileDescriptorName= setting for socket unit files to set the name for fds created by socket units. This also adds a new call sd_listen_fds_with_names(), that is similar to sd_listen_fds(), but also returns the names of the fds. systemd-activate gained the new --fdname= switch to specify a name for testing socket activation. This is based on #1247 by Maciej Wereski. Fixes #1247.
2015-09-29core: allow setting WorkingDirectory= to the special value ~Lennart Poettering
If set to ~ the working directory is set to the home directory of the user configured in User=. This change also exposes the existing switch for the working directory that allowed making missing working directories non-fatal. This also changes "machinectl shell" to make use of this to ensure that the invoked shell is by default in the user's home directory. Fixes #1268.
2015-09-16cgroup: add support for net_cls controllersDaniel Mack
Add a new config directive called NetClass= to CGroup enabled units. Allowed values are positive numbers for fix assignments and "auto" for picking a free value automatically, for which we need to keep track of dynamically assigned net class IDs of units. Introduce a hash table for this, and also record the last ID that was given out, so the allocator can start its search for the next 'hole' from there. This could eventually be optimized with something like an irb. The class IDs up to 65536 are considered reserved and won't be assigned automatically by systemd. This barrier can be made a config directive in the future. Values set in unit files are stored in the CGroupContext of the unit and considered read-only. The actually assigned number (which may have been chosen dynamically) is stored in the unit itself and is guaranteed to remain stable as long as the unit is active. In the CGroup controller, set the configured CGroup net class to net_cls.classid. Multiple unit may share the same net class ID, and those which do are linked together.
2015-09-10core: add support for the "pids" cgroup controllerLennart Poettering
This adds support for the new "pids" cgroup controller of 4.3 kernels. It allows accounting the number of tasks in a cgroup and enforcing limits on it. This adds two new setting TasksAccounting= and TasksMax= to each unit, as well as a gloabl option DefaultTasksAccounting=. This also updated "cgtop" to optionally make use of the new kernel-provided accounting. systemctl has been updated to show the number of tasks for each service if it is available. This patch also adds correct support for undoing memory limits for units using a MemoryLimit=infinity syntax. We do the same for TasksMax= now and hence keep things in sync here.
2015-09-06nspawn: add new .nspawn files for container settingsLennart Poettering
.nspawn fiels are simple settings files that may accompany container images and directories and contain settings otherwise passed on the nspawn command line. This provides an efficient way to attach execution data directly to containers.
2015-08-24core: optionally create LOGIN_PROCESS or USER_PROCESS utmp entriesLennart Poettering
When generating utmp/wtmp entries, optionally add both LOGIN_PROCESS and INIT_PROCESS entries or even all three of LOGIN_PROCESS, INIT_PROCESS and USER_PROCESS entries, instead of just a single INIT_PROCESS entry. With this change systemd may be used to not only invoke a getty directly in a SysV-compliant way but alternatively also a login(1) implementation or even forego getty and login entirely, and invoke arbitrary shells in a way that they appear in who(1) or w(1). This is preparation for a later commit that adds a "machinectl shell" operation to invoke a shell in a container, in a way that is compatible with who(1) and w(1).

2014-11-24smack: introduce new SmackProcessLabel optionWaLyong Cho
In service file, if the file has some of special SMACK label in ExecStart= and systemd has no permission for the special SMACK label then permission error will occurred. To resolve this, systemd should be able to set its SMACK label to something accessible of ExecStart=. So introduce new SmackProcessLabel. If label is specified with SmackProcessLabel= then the child systemd will set its label to that. To successfully execute the ExecStart=, accessible label should be specified with SmackProcessLabel=. Additionally, by SMACK policy, if the file in ExecStart= has no SMACK64EXEC then the executed process will have given label by SmackProcessLabel=. But if the file has SMACK64EXEC then the SMACK64EXEC label will be overridden. [zj: reword man page]
2014-09-08bus: parse BusPolicy directive in service filesDaniel Mack
Add a new directive called BusPolicy to define custom endpoint policies. If one such directive is given, an endpoint object in the service's ExecContext is created and the given policy is added to it.
2014-06-05kdbus: when uploading bus name policy, resolve users/groups out-of-processLennart Poettering
It's not safe invoking NSS from PID 1, hence fork off worker processes that upload the policy into the kernel for busnames.
2014-06-04core: rename ReadOnlySystem= to ProtectSystem= and add a third value for ↵Lennart Poettering
also mounting /etc read-only Also, rename ProtectedHome= to ProtectHome=, to simplify things a bit. With this in place we now have two neat options ProtectSystem= and ProtectHome= for protecting the OS itself (and optionally its configuration), and for protecting the user's data.
2014-06-04socket: add new Symlinks= option for socket unitsLennart Poettering
With Symlinks= we can manage one or more symlinks to AF_UNIX or FIFO nodes in the file system, with the same lifecycle as the socket itself. This has two benefits: first, this allows us to remove /dev/log and /dev/initctl from /dev, thus leaving only symlinks, device nodes and directories in the /dev tree. More importantly however, this allows us to move /dev/log out of /dev, while still making it accessible there, so that PrivateDevices= can provide /dev/log too.
2014-06-03core: add new ReadOnlySystem= and ProtectedHome= settings for service unitsLennart Poettering
ReadOnlySystem= uses fs namespaces to mount /usr and /boot read-only for a service. ProtectedHome= uses fs namespaces to mount /home and /run/user inaccessible or read-only for a service. This patch also enables these settings for all our long-running services. Together they should be good building block for a minimal service sandbox, removing the ability for services to modify the operating system or access the user's private data.
2014-05-22cgroup: rework startup logicLennart Poettering
Introduce a (unsigned long) -1 as "unset" state for cpu shares/block io weights, and keep the startup unit set around all the time.
2014-05-22core: add startup resource control optionWaLyong Cho
Similar to CPUShares= and BlockIOWeight= respectively. However only assign the specified weight during startup. Each control group attribute is re-assigned as weight by CPUShares=weight and BlockIOWeight=weight after startup. If not CPUShares= or BlockIOWeight= be specified, then the attribute is re-assigned to each default attribute value. (default cpu.shares=1024, blkio.weight=1000) If only CPUShares=weight or BlockIOWeight=weight be specified, then that implies StartupCPUShares=weight and StartupBlockIOWeight=weight.

2014-03-07busname: add parser for bus name policiesDaniel Mack
There are three directives to specify bus name polices in .busname files: * AllowUser [username] [access] * AllowGroup [groupname] [access] * AllowWorld [access] Where [access] is one of * 'see': The user/group/world is allowed to see a name on the bus * 'talk': The user/group/world is allowed to talk to a name * 'own': The user/group/world is allowed to own a name There is no user added yet in this commit.

2014-03-03core: move config_parse_set_status() into load-fragment.cLennart Poettering
Let's keep specific config parsers close to where they are needed. Only the really generic ones should be defined in conf-parser.[ch].
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.
2014-02-26core: add new RestrictAddressFamilies= switchLennart Poettering
This new unit settings allows restricting which address families are available to processes. This is an effective way to minimize the attack surface of services, by turning off entire network stacks for them. This is based on seccomp, and does not work on x86-32, since seccomp cannot filter socketcall() syscalls on that platform.
2014-02-21core: Add AppArmor profile switchingMichael Scherer
This permit to switch to a specific apparmor profile when starting a daemon. This will result in a non operation if apparmor is disabled. It also add a new build requirement on libapparmor for using this feature.

architecture support for system calls Also, turn system call filter bus properties into complex types instead of concatenated strings.
2014-02-12core: rework syscall filterLennart Poettering
- Allow configuration of an errno error to return from blacklisted syscalls, instead of immediately terminating a process. - Fix parsing logic when libseccomp support is turned off - Only keep the actual syscall set in the ExecContext, and generate the string version only on demand.

2013-11-25conf-parser: distinguish between multiple sections with the same nameTom Gundersen
Pass on the line on which a section was decleared to the parsers, so they can distinguish between multiple sections (if they chose to). Currently no parsers take advantage of this, but a follow-up patch will do that to distinguish [Address] Address=192.168.0.1/24 Label=one [Address] Address=192.168.0.2/24 Label=two from [Address] Address=192.168.0.1/24 Label=one Address=192.168.0.2/24 Label=two
2013-10-19mount/service: drop FsckPassNo supportTom Gundersen
We now treat passno as boleans in the generators, and don't need this any more. fsck itself is able to sequentialize checks on the same local media, so in the common case the ordering is redundant. It is still possible to force an order by using .d fragments, in case that is desired.
2013-07-11cgroup: split out per-device BlockIOWeight= setting into BlockIODeviceWeight=Lennart Poettering
This way we can nicely map the configuration directive to properties and back, without requiring two different signatures for the same property.
2013-06-27core: general cgroup reworkLennart Poettering
Replace the very generic cgroup hookup with a much simpler one. With this change only the high-level cgroup settings remain, the ability to set arbitrary cgroup attributes is removed, so is support for adding units to arbitrary cgroup controllers or setting arbitrary paths for them (especially paths that are different for the various controllers). This also introduces a new -.slice root slice, that is the parent of system.slice and friends. This enables easy admin configuration of root-level cgrouo properties. This replaces DeviceDeny= by DevicePolicy=, and implicitly adds in /dev/null, /dev/zero and friends if DeviceAllow= is used (unless this is turned off by DevicePolicy=).
2013-06-17core: add new .slice unit type for partitioning systemsLennart Poettering
In order to prepare for the kernel cgroup rework, let's introduce a new unit type to systemd, the "slice". Slices can be arranged in a tree and are useful to partition resources freely and hierarchally by the user. Each service unit can now be assigned to one of these slices, and later on login users and machines may too. Slices translate pretty directly to the cgroup hierarchy, and the various objects can be assigned to any of the slices in the tree.
2013-04-23unit: rework trigger dependency logicLennart Poettering
Instead of having explicit type-specific callbacks that inform the triggering unit when a triggered unit changes state, make this generic so that state changes are forwarded betwee any triggered and triggering unit. Also, get rid of UnitRef references from automount, timer, path units, to the units they trigger and rely exclsuively on UNIT_TRIGGER type dendencies.
2013-04-17Report about syntax errors with metadataZbigniew Jędrzejewski-Szmek
The information about the unit for which files are being parsed is passed all the way down. This way messages land in the journal with proper UNIT=... or USER_UNIT=... attribution. 'systemctl status' and 'journalctl -u' not displaying those messages has been a source of confusion for users, since the journal entry for a misspelt setting was often logged quite a bit earlier than the failure to start a unit. Based-on-a-patch-by: Oleksii Shevchuk <alxchk@gmail.com>
2013-02-27unit: rework resource management APILennart Poettering
This introduces a new static list of known attributes and their special semantics. This means that cgroup attribute values can now be automatically translated from user to kernel notation for command line set settings, too. This also adds proper support for multi-line attributes.
2013-02-11core: properly validate environment data from Environment= lines in unit filesLennart Poettering
2012-07-19use #pragma once instead of foo*foo #define guardsShawn Landden
#pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers
2012-07-17execute: support syscall filtering using seccomp filtersLennart Poettering
2012-06-22unit: drop the Names= optionLennart Poettering
Names= is a source of errors, simply because alias names specified like this only become relevant after a unit has been loaded but cannot be used to load a unit. Let's get rid of the confusion and drop this field. To establish alias names peope should use symlinks, which have the the benefit of being useful as key to load a unit, even though they are not taken into account if unit names are listed but they haven't been explicitly referenced before.

2012-05-24main: add configuration option to alter capability bounding set for PID 1Lennart Poettering
This also ensures that caps dropped from the bounding set are also dropped from the inheritable set, to be extra-secure. Usually that should change very little though as the inheritable set is empty for all our uses anyway.
2012-05-21units: introduce new Documentation= field and make use of it everywhereLennart Poettering
This should help making the boot process a bit easier to explore and understand for the administrator. The simple idea is that "systemctl status" now shows a link to documentation alongside the other status and decriptionary information of a service. This patch adds the necessary fields to all our shipped units if we have proper documentation for them.
